EXECUTIVE SUMMARY

Introduction

The original Project, (NUWSRP-II) with an IDA credit of US$ 200 million (IDA Credit No. 4086-UNI), was approved on July 15, 2005 in order to address some of the above deficiencies in water supply services. The Project's Development Objectives were to (i) improve reliability of water supply produced by the water treatment works in Lagos State; (ii) increase access to piped water networks in four cities in Cross River State; and (iii) improve commercial viability of the urban water utilities in Participating States. The project was made up of four components: (a) rehabilitation and systems expansion, (b) public private partnership development, (c) service sustainability and project management, (iv) institutional development and policy reform. As a result of the successful implementation of NUWSRP 2 in the 2 states, the FGN is requesting an additional financing of US$150 million from the International Development Association (IDA) for Cross River state. The proposed additional credit will help finance the scaling up of the project activities in Cross River state by supporting the construction of 3 additional water supply systems in Itigidi, Obubra and Okpoma towns in the northern part of the state. A project extension of 3 years is proposed to cover the above activities.

The proposed civil works of the Water Supply Scheme include:- • Construction of Intake and Weir; • Construction of Low and High Lift Pumping Stations; • Construction of Water Treatment Plants; • Construction of Ground Level Reservoirs; • Construction of Elevated Water Tanks; • Constructions of Kiosk and house connections; • Supply and lying of water supply pipes to cover approximately over 100km of sizes ranging

from OD 75mm – OD 500mm including accessories etc; and • Construction of water kiosks and supply and installation of house connection, including

pipes, accessories, conventional credit water meters with automatic meter reading (AMR) capabilities.

Purpose and Scope of the ESIA

The purpose of the ESIA is to identify the major issues and impacts associated with the project and to identify mitigation measures required to limit any such impacts to acceptable levels. The scope of the ESIA may be summarized as follows: • Assess the potential environmental and social impacts of the sub-, whether positive or negative

and propose effective mitigation measures for the negative impacts; • Inform the project team- Cross River State Water Board Limited- Project Implementation Unit

(CRSWB-PIU) and the CRSG of the potential impacts of different projects activities and relevant mitigation measures and strategies to be undertaken;

• Develop an Environmental and Social Management Plan (ESMP) to ensure successful mitigation of all negative adverse impacts, a tangible monitoring indicator and plan, Estimate mitigation cost and institutional arrangements to execute this plan; and to provide clear instructions to works supervisors and contractors with regard to any measures that need to be implemented in order to limit any potential negative impacts to acceptable levels.

• Identify environmental policies, legal and institutional framework pertaining to the project. • Access the existing institutional capacity to implement the ESMP and suggest measures for

capacity gap development.

1.4 ESIA Process

The ESIA process details the methodology for the assessment and management of environmental issues in any development project. This includes screening, scoping, baseline/ data collection, identification of potential environmental impacts and required management action steps to be taken. The applied ESIA process is presented below, while further site details are shown in chapter 5 of this report. • Stage 1: Screening: This includes an analysis of the proposed project’s terms of activities to be

undertaken, and facility to be established in order to determine the suitability or otherwise of project and whether EA was needed and the scale of impact. This was done using the World Bank safeguards policies, ISO 14001 checklist criteria and best professional judgment. The outcome of this is that the proposed project requires environmental assessment, and is a category B project.

• Stage 2: Scoping: Determines any project activities and facilities that might potentially cause

interferences with the environment and society. Furthermore, determines any particular environmental sensitivities and conditions that are of relevance to the proposed project. This includes a reconnaissance level visit and full field visit to the various project locations.

• Stage 3: On the basis of the analysis in stages 1 and 2, identify any potential impacts of the

project on the environment. Depending on the nature of the project activities and facility, as well as specific environmental conditions, the potential significance of such impacts is determined.

• Stage 4: Identifies and reviews relevant measures to be taken in order to prevent or reduce any

potential adverse impacts to acceptable levels. Furthermore, measures for monitoring and control impacts, including verification of the proposed mitigations measures are determined.

• Stage 5: Where impacts may not be successfully prevented or reduced to acceptable levels,

measures are defined to either recover environmental conditions, or compensate for unavoidable damage.

• Stage 6: Summary of impacts- The predicted adverse environmental and social impacts for

which mitigation is required should be identified and summarized. • Stage 7: Description of mitigation measures - The ESMP identifies feasible and cost effective

measures to reduce potentially significant adverse environmental and social impacts to acceptable levels.

• Stage 8: Description of monitoring program- environmental performance monitoring should be

designed to ensure that mitigation measures are implemented, have the intended result, and remedial measures are undertaken if mitigation measures are inadequate or impacts have been underestimated within the ESIA report. It should also assess compliance with national guidelines and World Bank s OP 4.01 (Environmental Assessment).



4

• Stage 9: Institutional arrangements: Responsibilities for mitigation and monitoring should be clearly defined. The EMP will identify arrangements for coordination between the various actors responsible for mitigation.

• Stage 10: Cost estimates: These should both the initial investment and recurring expenses for

implementing all measures contained in the ESMP and then integrated into the total project costs.

1.5 Study Approach and Methodology

The ESIA will be prepared in accordance with:

• World Bank Safeguard Policy- Operational Policy (OP/BP 4.01): Environmental Assessment,

and • Nigerian Government - Environmental Impact Assessment (EIA) Act No. 86 of 1992

A multi-methodological approach was used for the ESIA study to cover the following principal areas: • Project organization and planning, • Environmental Assessment, and • Socio-economic Assessment

Details of the assessment methodologies are as follows:

1.5.1 Organization and Planning

Project organization and planning was undertaken by collecting relevant materials and information about the project; and a desk review of the literatures. The materials collected and reviewed include:

• The gazette of the Nigerian regulatory framework, • Project Appraisal Document (PAD) of the NUWSRP2,

• World Bank Safeguard Policies especially Environmental Assessment Safeguard Policy (OP 4.01),

• the general environmental management conditions for construction contracts, engineering and technical designs, work requirements of the treatment plants and other extension/densification of Cross River water distribution system,

• baseline information relating to the physical, biological and socio-cultural environment of Ikom, Obudu and Ogoja, and the entire Cross River State (including the climatic conditions),

• the Constitution of the Federal Republic of Nigeria, numerous relevant Federal, State, and local laws, regulations, decrees, acts, and guidelines,

• The harmonized Environmental and Social Management Framework (ESMF) of the National Urban Water Sector Reform Project (NUWSRP),

• Resettlement Policy Framework (RPF) of NUWSRP, and

• Baseline information relating to the physical, biological and socio-cultural environment of Cross River State (including the climatic conditions),

1.5.2 Environmental Study

Environmental study was based on:

Reconnaissance level survey

This was the first level visit to the project area to familiarize with the proposed facility sites and the geo-physical conditions of the project area. It also included visits to institutions and authorities who would partner in the implementation process as well as the various communities that this project would be impacting; being the first stage of public consultation. This occurred along side the socio-economic survey

Water quality study Water samples for analysis were collected daily from various sources of water used by the communities; including the proposed water extraction sources for the project. Water was collected as a composite sample at each sample station. At each time of water collection, two separated set of samples were collected, one for the determination of heavy metals and the other for the determination of physico-chemical parameters. Water samples were collected in plastic containers after being rinsed with ambient water from each station and labeled accordingly. Analysis of pyhsico-chemical parameters was determined in the laboratory, while heavy metals were determined using the Atomic Absorption Spectrometer (AAS). Water quality analysis in relation to the study is to determine the bacteria loads, level of metal composition and chemicals, and subject them to the WHO/Nigerian Federal Ministry of Environment standards for drinking water. Quality control of water collection was ensured by: • Ensuring that professionals only collect water samples • Wearing hand gloves • Immersing the container inside the water and stoppering below surface water

• Transporting samples to laboratory for analysis within 24 hours of collection.

Soil Quality study Soil samples were collected from locations of various proposed constructions and installations. This was also collected from the water resources sites being used or proposed for this water scheme project for the purpose of determining the existing physico-chemical soil conditions. Quality control of soil collection entailed;

o removing the topsoil, and collecting soil below 2cm from the surface soil-level, o Air drying soil samples o Labeling of each soil sample, o Transporting samples to laboratory for analysis within 24 hours of collection.

This involved visits to all the communities of project influence in the 3 project areas. All the proposed locations for facility constructions including the intake and weirs were visited to observe the nature of the environmental conditions.

Air and Noise Quality

Using air and noise quality equipment, the experts tested surveyed proposed sites in all the project areas. The analysis was subjected to the standards given by the Federal Ministry of Environment in Nigeria. This will help during implementation for pollution control and compliance monitoring.

1.5.3 Social, Economic and Health Study

The first step adopted was to visit authorities and communities that this project would be impacting. The community consultation as a tool of social study would not only community participation and sustainable development, but was used to create awareness of the questionnaire to be administered to the households in the project areas; and at the same time was useful for eliciting the communicable health concerns of the project communities. Semi Structured Interview (SSI) questionnaire, a tool of Participatory Rural Appraisal (PRA) was used for data collection from the respondents. A sample of the SSI Questionnaire used for the field study is presented in Appendix 5. To ensure quality control of the field work, the following steps were taken: Field Interviewers/Enumerators

The instrument was administered by well-trained and tested research assistants and enumerators, under close supervision. Field enumerators were recruited based on the following: � Graduate from a higher institution; � Ability to speak the local language; � Familiarity with the project area. Training was held for all field enumerators and supervisors by the experts in the consulting firm. The training included: � Detailed explanation of the entire project; � The importance, and how to administer the questionnaires; � Field practices/ reconnaissance survey using the SSI; � Cross Checking of questionnaire filled by the research assistants enumerators during the field

practice to ascertain their ability to use the SSI.

1.6 Project Classification

The classification phase involves a preliminary screening that categorizes the proposed project, so as to determine the nature and extent of the environmental assessment needed. Projects are classified as category A, B or C (high, medium and low social or environmental risks) depending on the type, location (nearness to ecologically vulnerable areas), sensitivity and scale of the project, as well as the nature and magnitude of its possible impacts. • Category A: A proposed project is classified in this category if it is likely to have significant

adverse environmental impacts that are sensitive (and may be irreversible), diverse or unprecedented. These projects may affect an area broader than the sites or facilities subject to physical work.



7

• Category B: A proposed project receives this classification if it has potential environmental

impacts on human populations or environmentally important areas –including wetlands, forests, grasslands, and other natural habitats –that are less adverse than those of Category A projects. These impacts are site-specific; few if any of them are irreversible; and in most cases mitigation measures can be designed more readily than for Category A projects.

• Category C: A proposed project is classified as a Category C if it is likely to have minimal or no

adverse environmental impacts.

This project is classified as a Category B project because: o Its impacts are site specific o Its impacts are reversible, or in most cases have practical mitigation measures o Most of its impacts fall within medium and low ratings.

As a result of the above justification and classification, this project is classified as a Category B (medium impacts) project. It is therefore required that an Environmental and Social Impact Assessment (ESIA) be prepared. This ESIA report is prepared as a stand alone document for ease of implementation by the CRSWBL.

2 PROJECT DESCRIPTION

2.1 Project Rationale

The Cross River State Government considers the provision of potable water as a critical element in its policy for sustainable economic development and poverty reduction. The project’s principal development outcomes are:

• Increased reliability and financial viability of selected urban water utilities; • Increased access to piped water networks in selected urban areas; and • Improve financial viability of the urban water utilities in the selected urban areas

of Cross River State. Progress toward these principal development outcomes will be measured through:

• The increase in water delivered through existing and extended networks; • Improvements in cost recovery, especially the degree to which operating costs

are recovered from water sales revenues in Cross River State; and • Increase in the number of households having access to the piped water network.

2.2 Project Components

The proposed civil works of the Water Supply Scheme include:-

• Construction of Intake and Weir; • Construction of Low and High Lift Pumping Stations; • Construction of Water Treatment Plants; • Construction of Ground Level Reservoirs; • Construction of Elevated Water Tanks; • Supply and lying of water supply pipes to cover approximately over 100km of sizes

ranging from OD 75mm – OD 500mm including accessories etc. • Construction of about 130 water kiosk and supply and installation of house

connection, including pipes, accessories, conventional credit water meters with automatic meter reading (AMR) capabilities for approximately 1,500 house connection.

The CRSWBL commissioned detailed engineering design for these civil works for these civil works to result in construction specifications and drawings for inclusion in the tender documents; this work has been carried by SGI Consulting Engineers Limited.

2.3 Project Environment

From field survey and expert review of the feasibility report of the proposed sites the site information of the various facilities across the three (3) project areas are presented as follows:

Obubra site information: Intake and Weir Site The intake and weir plant is located by the river bank of River Cross at Adun Beach. The land take is about 50m x 100m. Activities around the river bank include crop cultivation, while fishing is said to take place at a distance as a result of constant human activities by the community which have drove aquatic habitats afar–off. There are no buildings and/or habitations within the area. Access to the treatment plant is through motor-bike. Raw water extraction is from River Cross which bisects Itigidi, Obubra, Ikom and flows through to Republic of Cameroun. The River is massive, and has a historical record of large water resources at both dry and rainy seasons (SGI Ingenierie SA of Geneva, 2009).

Treatment Plant Site: The proposed treatment plant site is located at the left bank side of Adun Beach village about 500m away from the intake site. It is a communal land given to individuals for agricultural purposes. The total land space measures 350m x 250m. There is an uncompleted building project about 70m west of the proposed site. The site is located about 250m away from the regular settlements. Figure 2.1 shows the Obubra water treatment plant layout. Pipeline network route The water pipeline work is expected to follow along existing road path. The communities where the pipeline will pass through are mostly rural. Their major occupation is farming, with few people into petty trading. There are no private or community assets or means of livelihood to be affected by the pipeline work. However, intermittent obstruction to movement is expected. As a result of this, basic safety cautions for construction works will apply. Kiosk Construction sites The construction of kiosks will be done at various points within the settlements. It is expected to be situated on the Neighborhood on certification of feasibility study of proposed site. However, necessary sanitation plan and training is being proposed as an integral of the management plan.

Itigidi site information: Intake and Weir site The facility is using the existing intake site at Itigidi town, which lies about 200m away from the Itigidi town hall, and about 150m away from the existing water treatment plant. Raw water extraction is from River Cross which bisects Itigidi, Obubra, Ikom and flows through Republic of Cameroun. The River is massive, and has a historical record of large water resources at both dry and rainy seasons (SGI Ingenierie SA of Geneva, 2009)) Treatment Plant Site: The existing plant operating from that site is virtually redundant and will be replaced by the proposed new plant because the existing plant site is not large enough to accommodate the new plant. The new plant is about 300m away from the old site. It is on the side of the old market. The local authority has built a new market, and has offered the old market for the new water treatment plant. There is neither human habitation nor agricultural activities in the proposed site. Figure 2.2 shows the Itigidi water treatment plant layout. Pipeline network route The water pipeline work is expected to follow along existing road path for the most of the rural developing adjoining communities. In this area the settlement pattern is typically traditional with scattered and nucleated structures of houses made of mostly mud walls. However, pipeline in Itigidi town will follow the existing right of way. This will entail the rehabilitation of the existing pipeline network. This will obviously disrupt movement and affect private assets. Kiosk Construction sites The construction of kiosks will be done at various points within the settlements. It is expected to be situated on the Neighbourhood on certification of feasibility study of proposed site. However, necessary sanitation plan and training is being proposed as an integral of the management plan.

Okpoma site information Intake site The proposed intake site is situated on the Onwe River. The land is owned by the community and is located 4km away from settlement. The land was previously used for crop cultivation purpose until it was offered for use of the water scheme. Feasibility study carried out by SGI Ingenierie SA of Geneva (2009) on behalf Cross River State Water Board shows that Onwe River is large and feasible to serve the purpose of the scheme along with other competing local uses in both dry and rainy seasons.

Treatment Plant Site: The treatment plant is located in Idigbo-Okpoma, about 3 km distance away from settlement, and the land take is about 275M x 200M. The land is owned by the community, who has offered same for the facility. The site is located in a grass land space with no habitation. Surrounding land around the proposed site is used for farming by members of the community. The plan layout of the Okpoma water treatment plant is shown in figure 2.3. There is a road from Okpoma to the Onwe River that at present is motor-able only in the dry season but which, as part of the project, will be converted to an all-season laterite road. This will be of assistance to the farmers who till land in areas bordering this road and provide them an opportunity to move their produce to the market. Pipeline network route The water pipeline work is expected to follow along existing road path. The communities where the pipeline will pass through are mostly rural. The settlement pattern is typically traditional with scattered and nucleated structures of houses made of mostly mud walls. Their major occupation is farming. There are no private or community assets or means of livelihood to be affected by the pipeline work. However, intermittent obstruction to movement is expected.

The water supply system for Yala LGA and its surrounding communities is as follows:

• Surface water abstraction from Onwe River close to Udenyina by means of raw water

intake pumping station;

• A new water treatment plant will be built 1,700m inland from the water intake pumping

station ;

• From the new water treatment plant, a High Level Pumping Station (HLPS) will be

designed to supply water to 3 new Elevated Water Tanks (EWT) in Woleche

community (on the South West), Okpoma community (in the center) and close to the

LGA. In the height of Okpoma through a main pipe along the road to Okpinya to a T-

junction about 2km to these communities. From this junction, two pipes will be laid

down:

o The first will carry water to Woleche EWT straight south.

o The second pipe will convey water to Okpoma EWT through a HDPE pipe of

Ǿ450 and also convey water to EWT in the height of Okpoma close to LGA.

• At proposed treatment plant site, a small submersible pump will be installed in the clear

water tank to allow the filling of a small overhead reservoir to supply water to Udenyina

community.

Description of the proposed treatment work process The water treatment works will be a conventional process made up of pre-oxidation, flocculation/coagulation, settling tank/sedimentation, filtration and disinfection. Stage 1: Pre-oxidation and pH adjustment

• Pre-oxidation

The removal of metallic species in raw waters is possible by a physiochemical process: coagulation, flocculation and sedimentation. However, a pre-oxidation by chlorine gas improves this phenomenon: this reagent, effective over a wide pH range, is useful to oxidize metals, especially Iron, and Manganese. • pH adjustment Lime shall be added to get the optimal coagulation –flocculation pH (around 8.5). Stage 2: Coagulation The coagulation and flocculation processes facilitate the removal of total suspended solids (TSS), colloids and possibly precipitates of Iron and Manganese, which occurs in a final stage of solids-liquid separation (or sedimentation). Coagulation corresponds to the destabilization of colloidal particles brought about by the addition of a chemical reagent (a coagulant). Alum Sulphate will be dosed for this coagulation purpose.

Stage 3: Flocculation Flocculation process corresponds to the agglomeration of destabilized particles into microfloc, and later into bulky floccules which can be settled, called floc. The introduction of flocculants aid may promote the formation of flocs. The chosen and commonly used reagent is an anionic polymer (sold in powder form). This step requires a slow mixing tank (50 to 200 rmp).

Stage 4: Sedimentation The main purpose of settling is the separation technique most often used for TSS colloid, collected in the form of flocs after the coagulation and flocculation processes Sludge is composed of all the flocs settle on the bottom of the sedimentation tank. Sludge is extracted from this tank: 18h/day, and 7d/week; and will be sent to a special treatment for sludge, generated from water treatment. Stage 5: Sand filtration The use of rapid sand filter is a technique widely used in drinking water The purpose of sand filtration is to clear water by a physical removal of suspended solids (sludge) by passing through a medium (or more). A two layers filter, using two different media characteristics, is preferred to avoid the screening effect of a heterogeneous layer and to promote the penetration of impurities throughout the entire dept of the filter. The filter materials used have two layer and this are: anthracite and sand layer. The water flow is directed downwards, passing through the anthracite layer then the sand layer. The coarse particles are retained in the sand layer. A cleaning of the filter should be performed regularly to avoid clogging and bacteria growth. Backwashing is carried out with air and chlorinated waters.



29

Stage 6: Disinfection by chlorination In this stage, water flows from the sand filter to the chlorination tank. In this tank; chlorine is added to the water and allowed to settle for some time.

Chlorine is usually used in this stage because it is commonly applied to water for activation for most harmful micro-organisms.

Water Demand and Sludge treatment Water demand in the project area is estimated based on year 2025 estimate. The present population (based on 2006 Population Census figures) and nature of agricultural water demand was major considerations. Table 2.4 presents the water demand estimate and actual land proposed for treatment plant in each of the three (3) project areas.

Table 2.4: Water Demand and Treatment Plant Land Take

Sludge treatment must serve for the most to reduce these by-products in volume. The low organic load of raw waters induces a low fermenting capacity: a digestion process or a conditioning process is not required.

The chosen sludge treatment consists of: • A thickening by settling: sedimentation and homogenization of raw sludge

which produces a sludge that is still fluid; • A dewatering on drying beds: natural drainage.

o Thickening

The thickening process corresponds to an increase in the concentration of total solids (sludge) collected in the settling tanks. The sludge laden suspension is fed into a tank, where it remains for a lengthy retention time so that the sludge is compacted. The more concentrated sludge is extracted from the bottom, while the supernatant liquid is drawn off the top.

o Dewatering on drying beds

The use of drying beds requires no energy input and does not require much attention (maintenance). Only the natural phenomena of evaporation, drainage, perspiration can increase the dryness of the sludge.

• Sludge should be made toxic free for plant growth, and used as fertilizer for agricultural purposes.

Table 2.5 describes the proposed treatment process, with particular emphasis on the activities on waste/sludge generation. The table indicates the daily water intake and sludge production for each of the three (3) LGAs of project influence. Water intake for the facility is approximated by the daily water production quantity. Similarly, quantities of reagents used for water treatment which generate waste are also given. As seen table 2.5, when the proposed treatment plants are fully operational in 2035, Obubra LGA would generate the highest amount of sludge (1,291kg per day), then Abi LGA , with (637kg per day) and finally Yala LGA (573 kg / day).

3 BASELINE INFORMATION

This chapter gives an overview of the total project area of intervention and a visual imagery of the three (3) project sites in Cross River State. This imagery shows the various communities to be impacted by the project and various infrastructures of the proposed water scheme.

3.1 General overview

Nigeria is situated in West Africa and bordered to the north by Niger republic; north east by Chad; west by Benin; east by Cameroon and south by the Atlantic Ocean. The land mass of Nigeria is 923,768 sq km, and lies between latitudes 40 00’ N and 140 00’ N, and longitudes 20 50’ E and 140 45’ E.

Cross River state is a coastal in nature and located in the South Eastern Nigeria. This state was created in May 1967 from the former Eastern Region. It occupies 20,156m2 and shares boundaries with Benue state to the north, Enugu and Abia states to the west, Cameroon Republic to the east and Akwa-Ibom state and the Atlantic Ocean to the south.

Abi LGA

This project area comprises of Itigidi town and 12 communities (Table 2.1). Itigidi town serves as the headquarters of Abi L.G.A of Cross Rivers State. Itigidi town is located between latitude 050

53.083'N and longitude 80 8.25'E. The town is situated at upper course bank of the Cross River. Abi L.G.A had a population of 78,117 people (NPC, 2006). It has a clustered settlements pattern with scattering adjourning villages. The town accommodates a water pump station and treatment plant for the CRSWBL along the Old Park area and a reservoir along Hospital road.

Access to Itigidi town is through the Ugep-Ediba-Itigidi road that branches off the Calabar-Ikom highway at Ugep. Until recently, this road stopped at Ediba town, and Itigidi town could only be reached by ferry or speed boat: however the recently-commissioned bridge across the Cross River has made it possible to access Itigidi town by road.

Obubra LGA

Obubra town is about 175km north of Calabar with access through the Calabar – Ikom road from Apiapum. Obubra LGA has a population of 102, 294 people (NPC, 2006). Obubra Town, the headquarters of the Obubra L.G.A, is located about 175km North of Calabar, the State capital. Access to Obubra is through a branch off from the main Calabar-Ikom highway, at Apiapum. Obubra people are predominantly farmers and produce food crops such as garri, yam, groundnut and maize. Obubra can be classified as a semi-urban town and has a linear settlement pattern; with houses aligning along the main road. Obubra town has a record of being previously connected to the water board mains.



32

Yala LGA The project area in Yala LGA comprises of Okpoma town (LGA headquarters) and 11 other communities (see table 2.1). Okpoma town is situated along the major road from Ogoja to Abakaliki (capital of Eboinyi state), with a long stretch out of linear settlement along the road. Yala Local Government Area is carved out of Ogoja province and is situated approximately 300km North of Calabar and 20km from Ogoja. It has a population of 79, 400 people. Yala people are predominantly farmers and a little of small scale salt mining. It has many salt ponds which are of historic importance to the Yala people. The surrounding villages include Olachor, Itega, Okpodu, Alachor, Woleche etc.

3.2 Physical Environment

Geology The Coastal Plain of Cross River state is generally characterized by sandstones with lenses of clay and gravel. The major aquifers are mainly sandstone. Cross River state is blessed with abundant surface water (natural lakes, artificial reservoirs ponds, small perennial streams, springs and rivers) and ground water. The vast majority of the rural people obtain water for domestic use from the rivers, streams and wells. Ground water resources may vary depending on the location. On the coastal plain, in Akpabuyo, Calabar Municipality and part of Odukpani, there are excellent aquifers. Calabar and other major towns of Ogoja, Obudu, Ikom and Obubra are served by piped borne water from rivers and boreholes manned by the CRSWBL. Apparently, Cross River State occupies the catchments of River Cross which crosses down the Cameroon Mountain, across the flat-lying Cross River Basin, into vast estuary located along the Southern Nigeria- Cameroon boarder. Climate The state is situated in the tropical rain forest belt, characterized by monsoon rains, with dry periods in the part and a periodically dry savannah climate in the northern part. The mean annual rainfall in Cross River is 3,300 mm, of which about 70% occur during the months of June to October. The mean daily maximum and minimum temperature varies between 21.oC to 32oC in January and 25.05oC and 27.4oC in July and August respectively; the relative humidity ranges between a maximum of 98% throughout the year and a minimum of 60% in February; the average monthly evaporation ranges between 4.3 mm/day in February and 2.3 mm/day in July. Vegetation The vegetation of Cross River State is made up of tropical forest and the mosaic forest vegetation for most part of the southern areas which also extends to Itigidi, Obubra and Okpoma, while Ogoja has a combination of savannah and forest vegetations.



34

Agriculture The state has one of the most richly endowed agricultural lands in Nigeria. Natural rubber, pineapple and palm oil are already established plantation products and the main raw materials export in the state. Cocoa, soya beans, food crops such as cassava, yam, rice, plantain, banana and maize are produced in abundant quantities. Transport Cross River State enjoys excellent road network with the rest of Nigeria. It has a direct road link with the middle belt and the north-eastern part of the country. Its location on the south-eastern extremity of the country, almost entirely isolated by rivers, warrants the maintenance of good road networks.

The two major road transportation arteries are the east-west Ikang-Calabar-Itu road and the north-south Calabar-Ikom-Yola road which are both currently in a state of disrepair. Cross river towns have good intra-city transportation, in addition to a good system of inter-city and inter-local government transportation. Sometimes canoes, tree trunks and ropes are the only means used by the local people to cross large rivers in remote settlement. On the coastal plain, in Akpabuyo, Calabar Municipality and part of Odukpani, there are excellent aquifers. Calabar and the other towns of Ogoja, Obudu, Ikom and Obubra are served by piped water from rivers and boreholes manned by the Cross River State Water Board Limited. Population Structure and Distribution Cross River State has a total population of 2,888,966 people with 1,492,565 Males and 1,396,501 Females spread across the 18 LGAs of the state.

Environmental Issues in Cross River State

As in most part of Southern Nigeria, the major environmental problems are soil degradation, urban air and water pollution, and rapid urbanization.

3.3 Baseline Data Analysis

In order to prepare the Environmental Social Impact Assessment of this project, baseline data of the project areas was collected. This was with a view to determining the ambient environmental and social conditions of the project communities. This serves the following purposes: • Necessary for identifying critical environmental aspects that may impair project

sustainability • Helps to measure/evaluate/compare the performance of the project during project

operation stage. • It helps to determine the suitable mitigation measures that will be applied to the

environmental impacts of the project.

Therefore, the following baseline data aspects were collected: • Air quality • Physiochemical quality of surface and underground water • Noise level • Climatic data • Socio-economic data • Vegetation and endangered species.

Salinity: Samples from Ekureku borehole and Adadama borehole are above the permissible limits. Those within permissible limit include: Egboronyi pond, Imina stream and Itigidi treated water plant Dissolved oxygen (DO): The DO values were high, hence permissible for aquatic life for samples from Imina spring and Itigidi treatment plant. All other samples were low, and not permissible. Chemical Oxygen Demand (COD): All the samples, except Abi borehole and Itigidi treatment were within permissible limits. Hardness: All the sampled water bodies in this area are permissible in terms of hardness. Phosphate: All the sampled water bodies in this area are permissible in terms of phosphate content. Ammonia: Ammonium was generally permissible for all the samples. Metals: All the heavy metals were permissible across the sampled locations. Coliforms: Salmonella sp. was present in the water sample from Egboronyi pond and absent in all other samples. Shigella sp. was absent across the samples, while E.Coli sp was only present in Adadama borehole water.

Table 3.4 Yala LGA Project Area: Water Quality Result


Temperature: The Temperature was relatively lower which is attributed to the wet and rainy season. The minimum and maximum temperature of 20.5 0 C and 36 0 C across the project areas are normal for tropical waters and falls within WHO permissible limits of 40 0C.

pH: The pH values along sampling stations in Idigbo borehole, Itega pond, Ochochi stream and Enimiri River are below WHO/FMEnv permissible limit of 6-9. These water samples are acidic while the water samples from Ipuole stream and Ochochi borehole are within permissible limit for drinking water.

Colour: Colour of water from the boreholes in this area are generally clear (less than 16 TCU^ WHO/Canadian permissible limit) while those from streams and river are not clear. This can be attributed to the human activities around the water bodies. Conductivity: The permissible limit for conductivity by FMEnv/WHO is 50 -125. Values recorded from the field in Yala showed high values for Idigbo borehole sample while the rest of the sampling stations where within permissible limits.

Salinity: Idigbo borehole is slightly above limit (not permissible). Similarly, samples from Ipuole stream and Ochochi borehole are above permissible limit. However, those within permissible limit are Itega pond, Itega stream, Ochochi stream and Enimiri River. This explains why the villagers have abandoned the use of water from those boreholes. Dissolved oxygen (DO): The maximum limit for DO (WHO/FMEnv) is 7.5. Samples from Ochochi stream and Enimiri River are permissible, while the rest of the sample water bodies fall below permissible limit, hence not permissible. Chemical Oxygen Demand (COD): WHO maximum permissible limit for COD in fresh/surface water is 250. COD is not permissible for Idigbo borehole and Ochochi borehole, while the rest of the sampling points are permissible for drinking. Hardness: Permissible limit for Total Hardness is 75-150mg/L. All the sampled water bodies in this area are permissible in terms of hardness. Phosphate: All the sampled water bodies in this area are permissible in terms of phosphate content.. Ammonia: Ammonium is generally within permissible limit across sampled water bodies in Yala LGA, but absent in Itega stream. Metals: All the heavy metals were permissible across the sampled locations, except cadmium, which values were not permissible in Idigbo borehole and Enimiri River. Coliforms: Under this compound are Salmonella sp, Shigelle sp and E.Coli. These bacteria are not permissible in domestic used water. All the 3 bacteria species are absent in Idigbo borehole sample, Enimiri River, and Ipuole stream. Salmonella sp. was present in Itega pond, Itega stream, Ochochi stream and Ochochi borehole. Shigella sp was confirmed present in Itega stream. The outcome of the water analysis in the three project areas indicate that the water sources being depended at present for drinking are harmful. The results are summarized as follows:

• For Okpoma project area, the waters are characterized by low inorganic/organic dissolved substances, considering chemical oxygen demand, dissolved oxygen, salinity acidity and presence of microbial coli forms,

• Itigidi project area shows significant presence of microbial flora and acidity; as well as high

concentrations in conductivity, salinity and dissolved oxygen,

• Obubra project area shows significant presence of microbial flora and acidity; as well as high concentrations in salinity and dissolved oxygen.

As a conclusion of water analysis, a required treatment plant would be composed of the steps listed in section 2.5.

Abi LGA Project Areas

Temperature: The ambient temperature in this area is within the permissible limit for a tropical environment. Hydrogen ion Concentration (pH): Only the sample from Imina hill top fall within the permissible limit. Acidic soils included those of Akarafor borehole site, Itigidi treatment plant area and Egboronye site. Only the soil from Adadama spring area was biased towards alkalinity. Phosphate: This is one of the major components of fertilizer and exceeds permissible limit of 1 for the soil sample from a farm near Ababane stream. Samples from Obubra main town and Ogaga stream sites were slightly above the standard limit. Phosphorous: Soils from Obubra main town, Adun Beach site, Ogada farm site, Owakande Borehole site, Ababane stream site, Ofodua borehole site and Iyamoyong junction farm site are above standard limit. Sulphate: All the tested soil samples fall within permissible limit. Nitrate: All the tested soil samples fall within permissible limit. Potassium: Highest potassium value of .3 was recorded from Itigidi treatment plant and Egboronye site samples, and the lowest limit (2.2) came from Imina hill top sample. Cadmium: All the soils samples except that from Imina hilltop were above standard limit for cadmium. Lead: The standard limit for this metal in soil is <0.1. However, all the soil samples except that of Imina hilltop (Adadama Community) exceeded the limit. Copper: The concentration of copper was permissible for Imina hill soil sample and high in all other samples. The fact that that many parameters were within standard limit in Imina hilltop site (Adadama community) relative to other sites of soil collection, may be attributed to low human activities within the area due to its altitude.

3.3.3 Air Quality/Meteorological and Noise Measurement

General Background This is the report of air quality/Meteorological and Noise measurement for ESIA for CRSWBL proposed water project covering Yala, Obubra and Abi LGAs. This exercise was conducted between September 29th to October 1st 2009 in accordance with FMEnv requirements using scientific and standard methods following regulatory requirements. A detail assessment is shown in Table 3.9 Regional Climatic / Meteorological Characteristics The overview of climatic/meteorological features (rainfall, air temperature, relative humidity, wind direction/speed and sunshine) of the study area presented herein is based primarily on information from literature research and field study. Climatic Condition The weather and climate of the entire Niger Delta area is closely tied to the general mesoscale trend in Nigeria. It follows that the weather regime experienced at any given location in Nigeria during the year is determined primarily by geographical location in relation to the fluctuating position of the Inter Tropical Convergence Zone (ITCZ) (Ayoade, 1983). In this regard the predominant weather regime in the study area is warm and humid. The project area is within the humid tropical zone with defined dry (December – March) and wet (April – November) seasons. The wet season is brought about by the South – West (SW) trade wind blowing across the Atlantic Ocean. The dry, dusty and often cold North – East (NE) trade wind blowing across the Sahara desert dominates the dry season and brings a short spell of harmattan. Data on the climatic characteristics (rainfall, air temperature and relative humidity) of the area, collected over a 15 year period (1990 – 2005) from the Nigerian Meteorological Agency (NIMET) synoptic centre Calabar is presented below. Relative Humidity The mean monthly relative humidity of the study area is generally high and range between 71% and 88% (Figure 3.2) with a mean of 87.6%. Higher humidity values are recorded in July / August corresponding to the peak of the rainy season while lower values occur from December through February. The generally high mean relative humidity recorded within the study area could be attributed to the: nearness of the area to the coast; occurrence of cloud cover; influence of the moisture laden tropical maritime air mass; and influence of the south-west trade winds which dominate the area.

Rainy season commences in the study area around March and extends to November with July/August as the peak months, while the dry season occurs between December and February, reaching its peak in January when the harmattan wind sweeps across the entire area. More than 80% of the total annual rainfall is received between the months of May and October. A short dry period (August break) occurs between the last week of July and early August. The mean monthly rainfall over a 15 year period (1991–2005) ranged between 9.9mm in December and 377.9mm in July as shown in Figure 3.4. The total annual rainfall of the study area is in excess of 2,800mm.

Figure 3.4: Mean Monthly Rainfall in the Study Area

Winds The predominant wind direction in the area is south-west (SW) (210o - 240o) and this prevails for 8 months. Generally, wind speeds are between 1.5m/s and 2.0m/s and rarely exceed 2.5m/s. Wind speeds were observed to be lower at nights compared to values recorded during daytime hours. The highest wind speeds in the project area are recorded at the beginning of the rainy season - late March to early April. Visibility The weather in the project area on most days is cloudy owing to high relative humidity values recorded. Fogs are formed in the morning hours impairing visibility to less than 1000m. In June through September, being the most humid months, morning mist is usually prominent with visibility as low as 200m and remaining below 2000m for a number of days thus constituting a serious hazard to transportation. Generally, visibility, especially in the dry season is foggy in the early hours of the day and improves as the day progresses. Sunshine The mean daily sunshine in the area is between 5 and 6 hours in the dry season and 3 to 5 hours in the wet season. The area experiences a mean annual sunshine of 1,406 hours, which represents 31% of maximum possible amount of sunshine in the environment. The lowest values of sunshine are recorded between July and September with about 2 hours of sunshine per day due to greater amount of cloudiness in the sky.

Ambient Air Quality and Noise Level Air Quality The air quality assessment for the EBS of Cross River State Water Board (CRSWBL) proposed water project in Itigidi, Obubra and Okpoma is presented hereunder. The study areas are developed urban settlement with heavy transportation and industrial activities. Emissions from automobile and motor bike exhaust are the major sources of air pollution in the area. Air quality measurement was carried out in ten stations (PT1 – PT10) within the study area and data presented in Table 3.8. The FMENV limits for air emissions have been included for reference purpose.

Suspended Particulate Matter Suspended particulate matter (SPM) is finely divided particles which can originate naturally or be anthropogenic. It is present in ambient air in the form of dust, smoke and other aerosols. The most significant of these are less than 10µm in diameter and thus in the respirable size range (Canter and Hill 1977, SIEP 1995). High concentrations of suspended particulate matter (SPM) are known to irritate the mucous membranes and may initiate a variety of respiratory diseases. Fine particulates may cause cancer and aggravate morbidity and mortality from respiratory dysfunctions (CCDI, 2001). Also, it is known that dust coatings on leaf of plants reduces rate of photosynthesis and thereby reduces plants growth. It is also known that animals or humans that eat plants coated with SPM containing fluorides, arsenic, or lead may suffer some ill effects. SPM can also cause damage to materials by soiling clothing and textiles, corroding metals (at relative humidity above 75%), eroding building surfaces, and discoloring/destroying painted surfaces. The SPM levels recorded within the project area ranged from 10.3µg/m3 to 36.2µg/m3. The low SPM recorded in the area might be attributed to the time of sampling, low dust hays is usually recorded during the wet season due to wash down. The recorded levels are well below the FMENV recommended limit and thus do not pose any significant health effect. However, the proposed project implementation would result in dust generation and air emissions from the construction and operational phase of the water treatment plant. These may further lead to increases in SPM level of the areas.

Carbon Monoxide Carbon monoxide (CO) is a colorless odorless and tasteless gas produced by the incomplete combustion of carbonaceous materials or fossil fuels – gas, oil, coal and wood. Adverse health effect has been observed with carbon monoxide concentrations of 12 – 17ppm for 8 hours while prolonged (45 minutes to 3 hours) exposure to concentrations of CO between 200ppm and 800ppm often results in severe headache, dizziness, nausea and convulsions. However, the levels of CO recorded in the sampled areas were below equipment detection limit (0.1ppm), indicating an area free from CO pollution. Sulphur Oxides Sulphur dioxide (SOx) is a colourless gas produced from biological decay and forest fire releases. It is also produced from the combustion of sulphur-containing fuels, smelting, manufacture of sulphuric acid, incineration of refuse and production of elemental sulphur. The gas is known to be a causative agent of acid rain, it is harsh irritant and also capable of aggravating asthma, bronchitis and emphysema. It can also cause coughing and promote impaired functions in the human system (CCDI, 2001). Also, sulphuric acid aerosols (formed from dissolved sulphur dioxide) will readily attack building materials, especially those containing carbonates such as marble, limestone, and mortar. Sulphuric acid mists can also damage cotton, linen, rayon and nylon fabrics as well as paper. Excess exposure to sulphur dioxide accelerate corrosion rates for many metals such as iron, steel, zinc, and copper, especially at relative humidity over 70% (Peavy, et al, 1985). The colourless gas was not detected by the air pollutant equipment (detection limit 0.1ppm) during the field sampling exercise. Nitrogen oxides NOx are reactive gases called nitrogen oxides or oxides of nitrogen, which are formed during combustion processes. NOx results when fuel is combusted at high temperatures and occurs mainly from motor exhaust and stationary sources such as electric utilities and industrial boilers (Canter and Hill 1977). Nitrogen oxide is the only oxide of nitrogen that has been shown to have significant human health effects. Exposure to concentrations higher than 0.5ppm (1mg/m3) can trigger changes in pulmonary function in healthy people. At the time of survey, the NOx levels in the ambient air of the study area were below the equipment detection limit of 1.0ppm. Hydrogen Sulphide Hydrogen sulphide (H2S) is a toxic, odorous and corrosive gas, which is rapidly oxidized to SO2 in the atmospheres. Its presence in the atmosphere could result from storage tank and process vents. Exposure to concentrations in excess of 500ppm can be fatal (SIEP, 1995). H2S non-detection by the instrument used suggests that no activity leading to significant emission of the gas was going on in the vicinity of the study area at the time of survey. H2S level was below the equipment detection limit at the time of sampling. Hydrocarbons These include methane (CH4), ethane (C2H6), propane (C3H8) and other derivatives of aliphatic and aromatic organic compounds and are emitted from both man made and natural sources. Hydrocarbon vapour in the atmosphere arise from fugitive emissions, vents and incomplete combustion of fuels, particularly where fuel to air ratios are too high. Most members of this group are significantly toxic and exposure to high concentrations in the atmosphere (about 1000ppm or more) could result in interference with oxygen intake and acute leukemia. Members of the hydrocarbon family were not detected by the instrument used, indicating that no activity leading to significant hydrocarbon emission was taking place in the vicinity of the study area at the time of

this survey. The proposed project implementation will in no foreseeable way alter the ambient level of this gas in the area. Noise Level Noise is a periodic fluctuation of air pressure and noise pollution is defined as “unwanted sound”. The rate at which these fluctuations occur is the frequency, expressed in hertz (cycles per second). The range of sound pressures encountered is very large and to keep numbers in manageable proportions, noise levels are measured in decibels (dB) A, which have a logarithmic scale. In addition to causing a disturbance, excessive noise can damage health and have physiological effects. Environmental noise concerns focus on local communities and wildlife. Effects on local residents generally relate to the annoyance / nuisance caused by both short-and long-term high sound levels. Also, disturbance of wildlife is of significance particularly during breeding seasons. Noise measurement was carried out in ten (10) locations. These include all the air quality sample locations within the study area. The result of measurements is also presented in Table 3.9. The results of measurements showed that noise within the study area ranged from 53.9(dB) A to 95.8(dB) A. This result revealed that the noise levels were within the FMENV recommended limit all the sampled locations except at PT8 (old reservoir along Okpoma road) due to vehicular traffic and followed by PT1 (Itigidi Treatment Plant). The use of ear protective equipment is recommended for people working within this area as well as optimal maintenance of machines used in the area. However, the level of noise in the project area will be amplified during construction activities of the proposed project. This increase will however be short term and localized except around the treatment plant area during the operational period.

Sex Table 3.12 shows that about 86.8% of the respondents in the 3 LGAs of project influence are males while 13.2% are females. About 86.7% of respondents in Abi are males as against 13.3% for females. About 88% of the respondents in Obubra are males as against 12% for females. In Yala, 85.7% of the respondents are males while 14.3% are females. The general disproportionate in female representation is traced to:

• The survey technique in which head of household receives priority, while any other member of household responds if the household head is absent.

• Cultural practices in which females especially married women are not permitted to grant interview.

Age The field survey was administered to mostly household heads or to their adult relations, for those not present at the time of the survey. This informs that the field survey was biased towards adults from 30 years and above and this implies that the respondents come from an age category responsive enough to give detailed and valid data of their households and community.

Religion The overall mean result shows that Christianity is the dominant religion in the 3 LGAs. The practices of other religions are done by a few, and the overall mean representation is as follows:

• Christianity 95.4% • Traditional worshipping: 3.4%, • Islam: 0.3% • Others (not identified): 1%

Table 3.12 gives other religious statistics of the three project areas as follows:

• Christians are dominant across board, but 100% of Christian worshippers is found in Yala • Obubra has more percentage (6%) of traditional worshippers, while • Other private religions are prevailant in Abi (3%).

Marital Status Table 3.12 shows that the married persons are predominant among the respondents in all the project communities (79.2%). The percentages of divorce persons and widows are low ((1.46 and 3.97 respectively). The statistic is approximately even in the 3 LGAs of project areas.

Years Lived in the Community The field survey was administered to adults from 18 years and above. All the respondents are indigenes of their respective communities. This shows that the respondents are well acquainted with the socio-economic condition of the project areas, hence capable of given valid data. Household Size Table 3.12 shows a homogenous pattern of household sizes in the 3 project areas. The statistics shows that: • There are predominantly large household size (7 and above) across the project

communities. • Households with 1-3 persons are highest in Obubra (15%) and lowest in Abi (7%) • Large household size is highest in Abi (50.4%) and lowest in Obubra (47%).



60

The above implies high consumption of goods, and particularly, high need for water consumption in the project towns. It can also explain the reason for poverty in the area.

Highest Educational Qualification The survey (Table 3.12) shows that: • About 25% of the people of the 3 project areas are illiterates (did not attend primary school); • The percentage of people that attempted/finished primary school is highest in Abi (28.7%); • The percentage of those that attempted/finished secondary school is highest in Yala, while • People that went to tertiary institutions are highest in Abi (5.6%) and lowest in Yala (3.4%) Occupation Farming is the predominant occupation in the 3 local government areas of project influence. Other occupations practiced in the area are trading, civil/public service and self employment. The survey shows that: • Yala has the highest percentage of people whose primary occupation is farming (86.3), while

Obubra is least (66.7%) • Obubra has the highest number of people in trading (15.4%), while Yala has the least number

(7.2%). • The population of civil servants is highest in Obubra (17.9%) and lowest in Yala (9.3%). • The percentage of people in self employment is highest in Yala (9.3%) and lowest in Obubra

(5.6%). Annual Income The overall mean outcome of the survey shows that the proportion of people on income of N0 –N50,000 is predominant in the 3 project areas (60%), while those on income of N500,000 and above is lowest (2.2%). This indicates that the project area is dominated by people of low purchasing power. However, being a rural and agrarian area, the low income has less influence on their ability to feed their households and on their ability to respond to the proposed water utility bills.

Specifically the outcome of annual incomes in the 3 project areas is as follows: • Yala is the most impoverished with 79.3% of the people living on income of N0 - N50,000. • People on middle income of between N101,000 and N500,000 are highest in Obubra (16.9%);

the total frequency of 13.7% for the 3 project areas shows that the proportion is small. • The result shows that very little proportion (2.2%) of the population in the project area lives

on annual income of about N1,000,000 naira and above. In terms of the 3 project areas; Obubra has the highest proportion (3%), while Yala has the least (1.7%).

Source of Energy The survey shows that the entire project area is connected to the national grid, although power supply is sparingly across the project area. As a result of the unreliability of the public electricity, the study shows that: • Hurricane lamp is used by majority, while the highest frequency of this occurs inYala (78.7%),

and lowest in Obubra (48.7%) • The use of private generator as main source of energy is highest in Obubra (14%), and lowest

in Abi (3.1%).



61

In terms of energy used for cooking; • Fire wood is predominant in the 3 project areas; and its use is highest in Yala (86%) and lowest

in Obubra (70%) • The use of kerosene occurs mostly in Obubra (28%) and lowest in.Yala (14%). The predominant use of firewood has no significant effect on the project environment because: • The area is a rainforest zone with tall trees, • The woods in use are from farm sites, and • Shifting cultivation is practiced over the project area, in a 4-year rotation basis, which helps for

natural re-vegetation.

Source of Drinking Water The predominant source of water to the people of the project area is River, and serves about 50% of the population. Other available sources are: • Borehole (commercial and private); • Stream; and • Rain water. The survey gives the following details of sources of water in the 3 project areas: • Dependence on River water is highest in Obubra (78.1%) and lowest in Abi (22.6%); • Commercial borehole service is highest in Abi (21.5%) and lowest in Obubra (7.5%); • Dependence on stream or pond is most in Abi (45.6%) and lowest in Obubra ((9%), and • Private borehole is owned by very few people in Obubra (1%) and Yala (2.1%). It was found that households spend between N200 and N300 per day on the purchase of water during dry season.

The underlying outcome of this section is that the project is feasible in terms of recovery of its investment because water has an effective demand in the project area.

Willingness to Pay The people of the 3 project areas are generally willing to pay for water supply (Table 3.12). The highest amounts proposed to pay by the proposed consumers ranged from N200 to N1000. The average statistic shows that: • 56% of the household consumers from Yala want to pay N300 per month and makes up the

highest number in favor of that sum in the 3 project areas. • the highest in favor of N300 and this proportion is from Yala; • 72% of the proposed household consumers from Obubra are willing to pay N500 per

month. • The percentage of households willing to pay N1000 and more per month is relatively small

occurring highest in Abi (10%) and lowest in Yala (0%). The underlying outcome of this section is that the project investment outlay will be recovered according to plan.



62

Waste Disposal Practice Waste generated in the area is mainly domestic but lacks good waste management practices. Waste is disposed in the bush via open dump. This includes both degradable and non-degradable by-products.

Similarly, the predominant method of defecation is in the bush. This is common for the 3 local government areas. This finding is relevant for tracing the cause of some of the reported communicable disease, and particularly important for identifying the relevance of training and awareness on sanitation and hygiene during project implementation stage.

3.5 Health Impart Assessment

The outcome of the survey on health issues is shown on table 3.13 and shows the

following:

3.5.1 Obubra LGA Project areas

• The occurrences of Malaria and typhoid are high in this area and have led to several deaths of people, and have also been a drain on the household’s income.

• There are incidences of River blindness in this area, but the occurrence of River blindness is presently reduced following intervention from the .National Onchocerciasis Control Programme (NOCP).

• Guinea worm was a common health challenge in this area but the occurrence has been drastically reduced via the federal ministry of health’s intervention.

• Vibrio- cholera is said to occur in children under 5 years old. This is a form of diarrhoea in which patients experience frequent watery stool.

3.5.2 Abi LGA Project areas

• The occurrences of Malaria and typhoid are high in this area; leading loss of lives and incomes • The incidences of River blindness in this area are low. • Guinea worm was a common health challenge in this area but the occurrence has been

drastically reduced via the federal ministry of health’s intervention. • Vibrio- cholera is said to occur in children under 5 years old. • E.Coli sp related Dysentery occurs but with low frequency of incidences.

3.5.3 Yala LGA Project areas

• The occurrences of Malaria and typhoid are high in this area; leading loss of lives and incomes • The incidences of River blindness are absent. • There is no current history of Guinea Worm in this area.



63

• Vibrio- cholera is said to occur in children under 5 years old. Poor hygienic condition including drinking of bad water could be a major cause of Vibrio- choleric.

• E.Coli sp related Dysentery occurs but with low frequency of incidences. Unhygienic human activities and waste disposal within sources of drinking water or edible items could cause E.Coli sp Dysentery.

Details on the World Bank Safeguard Policies are presented in Appendix 1. With respect to this report, the following World Bank safeguard policy applies:

• Environmental Assessment (OP/BP4.01) The above-mentioned policy is reviewed below with regards to its applicability and implication. OP/BP4.01: Environmental Assessment This is a process whose breath, depth, and type of analysis depend on the nature, scale and potential environmental impact of the proposed project. It evaluates a project’s potential environmental risks and impacts in its area of influence; examines project alternatives; identifies ways of improving projects selection, siting, planning, design, and implementation by preventing, minimizing, mitigating, or compensating for adverse environmental impacts and enhancing positive impacts; and includes the process of mitigating and managing adverse environmental impacts throughout project implementation. The World Bank favours preventive measures over mitigatory or compensatory measures, whenever feasible. Environmental Assessment takes into account the following:

• natural environment; • human health and safety; • social aspects, and • trans - boundary and global environmental aspects.

4.2 Nigeria’ Regulatory Framework

With regards to management of the bio-physical environment throughout Nigeria, the overall responsibility was held by the now defunct Federal Environmental Protection Agency (FEPA), which was absorbed into the Federal Ministry of Environment (FME) in 1999. The State Environmental Protection Agencies or, as the case may be, State Ministries of Environment performs this function at state and local levels.

4.2.1 The Federal Ministry of Environment. (FMEnv)

The FMEnv’s mandate includes the establishment of federal water quality standards and effluent limitations, protection of air and atmospheric quality; protection of the ozone layer; control the discharge of hazardous substances; inter alia and ensures that all major development projects in Nigeria are subject to mandatory Environmental Impact Assessment (EIA) pursuant to EIA Act. No. 86 (Decree No. 86) of 1992. In the FMEnv, there is an Environmental Impact Assessment (EIA) Division, headed by a Director, to take all responsibility for EIA related issues. Also the EIA division in the FMEnv is the Impact Mitigation



65

Monitoring (IMM) branch, with a special responsibility for monitoring the implementation of Environmental Management Plans (EMP) contained in the approved EIAs. As contained in FEPA Acts 58 of 1988 and 59 of 1992. FME has put in place statutory documents to aid the monitoring, control and abatement of industrial waste. The statutory documents currently in place include: � National Policy on the Environment 1999 � National Environmental Protection (Effluent Limitations) Regulations (S.1.8) 1991 ; � National Environmental Protection (Pollution Abatement in Industries and Facilities Generating � Wastes) (S.1.9) 2004; � National Environmental Protection (Management of Solid and Hazardous Wastes) Regulations

(S.1.15) 1991; � Guidelines and Standards for Environmental Pollution Control in Nigeria 1991; � Sectoral Guidelines for EIA 1995 � Harmful Wastes (Criminal Provisions) Decree No. 42, 1988; � National Policy on the Environment, 1989; � Environmental Impact Assessment Procedural Guidelines 1995; � Environmental Impact Assessment (EIA) Act No. 86 of 1992; and � Environmental Impact Assessment (Amendments) Act 1999. � National Guidelines and Standards for Water Quality 1999 � National Guidelines on Environmental Management Systems (EMS) 1999 � National Guidelines on Environmental Audit in Nigeria 1999

These statutory documents clearly state the restrictions imposed on the release of toxic substances into the environment and the responsibilities of all industries whose operations are likely to pollute the environment. Such responsibilities include provision of anti-pollution equipment and adequate treatment of effluent before being discharged into the environment. The FMEnv has put in place procedural and Sectoral guidelines detailing the EIA process including a categorization of environmental projects into Categories I, II and III (referred to by the World Bank as categories A, B and C respectively). This project has been categorized as FMEnv -Category II or World Bank Category B. These guidelines require that a complete EIA be performed for Category I projects. Category II projects may not require an EIA depending on the screening criteria, while Category III projects do not require an EIA. The Sectoral guidelines on infrastructural development apply to this project. This water pipeline rehabilitation and installation project is classified as a category II project. ESIA’s are then submitted to the EIA Division of the FMEnv for approval and monitoring of the project during implementation and operation based on an Environmental Management Plan (EMP) in the ESIA.

4.2.2 International Guidelines and Conventions on Environment which Nigeria is signatory

• The United Nations Environmental Guidance Principles: This was adopted during Stockholm Convention on 16 June 1972. The principal objective of this convention was to provide guidelines (27 in number) for protecting the integrity of the global environment and the developmental system.



66

• Montreal Protocol on Substances that Deplete the Ozone Layer: The protocol was adopted in 1987 as an international treaty to eliminate ozone depleting chemical production and consumption. The protocol also called on industrialized countries to provide technical and financial assistance to developing countries and hence led to the Multilateral Fund for the Implementation of Montreal Protocol (MFMP).

• United Nations Convention on Biological Diversity: This convention was signed into law during the Rio Earth Summit in 1992. The convention places general obligations on countries to observe sustainable use and equitably share the plants and animals of the earth.

• United Nations Convention on Climate Change: The convention was signed in 1992 during the Rio Earth summit but put into force in 1994. The convention calls on developed countries and economies in transition to limit her emissions of the green house gases which cause global warming, although it does not impose mandatory emissions on developing countries.

• Convention to Regulate International Trade in Endangered Species of Fauna and Flora: This convention was signed into law in 1973 during the Washington summit and restricts the trade of fauna and flora species termed as endangered organisms.

• Convention on Conservation of Migratory species of Wild Animals: This convention also

known as the Bonn Convention of 1979 stipulates actions for the conversation and management of migratory species including habitat conservation.

• Vienna Convention for the Protection of the Ozone Layer: This convention was instituted in 1985 and places general obligation on the countries to make appropriate measures to protect human health and the environment against adverse effects resulting from human activities which tend to modify the ozone layer.

5.2.1 Impact Identification This involves characterizing the existing baseline environment and components of the

development project which are likely to impact the environment. A checklist of the associated and potential negative impacts from the water distribution project is presented in Table 5.1. The impacts identified have also been characterized as reversible or irreversible, direct or indirect, short or long term, permanent or temporary and cumulative as well as categorized as those under CRSWBL control and those which they have, influence over.

Reversible Impacts: the ability of the environmental components to recover their value after a

disturbance.

Irreversible Impact: impacts that permanently impair on the environmental component of the area.

Direct Impacts: these are impacts which follow as a direct cause-effect consequence of a

project activity. Indirect Impacts: Are environmental effects that are at least one step removed from project

activity in terms of cause-effect linkages.

Residual Impacts: These are impacts that remain even after mitigation measures have been applied.

Cumulative Impacts: Impacts arising from the interaction of project components or activities

with other activities of the past or those occurring simultaneously, or sequentially.

Beneficial Impacts: These are positive impacts.

Adverse Impacts: These are negative impacts. Long Term: Those predicted adverse impacts which remain after mitigating measures have been

applied.

Short Term: Impacts that are removed after mitigating measures have been applied.

Impacts under CRSWBL Control: impacts the organization has sole responsibility for.

Impacts under CRSWBL Influence: Impacts related to items provided by third party (contractor or supplier)

5.2.1 Determination of Impact Significance

An impact is said to be significant if it results in a change that is measurable in a statistically sound sampling program and if it persist, or expected to persist, more than several years at the population, community or ecosystem level (Buffington, 1976).

The determination of the significant associated and potential impacts of the proposed project was based on the ISO 140001 (EMS) framework using the criteria below:

5.2.2.1 Legal / Regulatory Requirements (L) – Is there a legal / regulatory requirements or

a permit required?

0 = There is no legal/regulatory requirement 3 = There is a legal/regulatory requirement 5 = There is a permit required

The legal/regulatory requirements were identified based on the World Bank Safeguards Policy, IFC performance standards and the Official Gazette of the Federal Ministry of Environment.

5.2.2.2 Risk (R) – What are risk / hazard rating based on risk assessment matrix (RAM)? 1 = Low risk 3 = Medium/intermediate risk 5 = High risk The risks were ranked based on three criteria namely, consequence, probability of occurrence and severity. These were determined using the RAM shown in Figure 5.2.

historical data and expert judgment? 1 = Low frequency 3 = Medium/Intermediate frequency 5 = High frequency The frequency of impact occurrence was determined using historical records of accidents/incidents, fatalities, etc, and consultation with experts. Importance of Affected Environmental Component and Impact (I) – what is rating of importance based on consensus of opinions? 1 = Low importance 3 = Medium/Intermediate importance 5 = High importance The importance of target environmental components on the potential impacts was determined through consensus among the project stakeholders.

5.2.2.4 Public Perception (P) – What is the rating of public perception and interest in proposed project and impacts based on consultation with stakeholders?

1 = Low perception and interest 2 = Medium/intermediate perception and interest 5 = High perception and interest Consensus of opinions among the project stakeholders was used to determine the public perception/opinion on the potential impacts.



75

The significant potential impacts of the proposed project (Table 5.2) were identified as those impacts to which the following conditions apply. (L + R + F +I + P) > 15 Sum of weight of legal requirements, risk factor, frequency of

occurrence, importance and public perception greater than or equal to the benchmark (15)

(F + I) is > 6: Sum of weights of frequency of occurrence and importance of affected environmental component exceeds the Benchmark (6). P = 5: The weight of the public perception/interest in the potential

impact exceeds the benchmark (5)

Itigidi, Obubra & Okpoma Water Distribution & Supply Scheme Environmental and Social Impact Assessment


5.5 Positive Environmental Impacts in the Locations

This sections looks at the main impacts identified, specifying these as much as possible according to the various infrastructural developments anticipated. The positive impacts for each phase are shown below.

Construction Phase

Increase in Business Opportunities and Employment: � Local subcontracts from the contractor during the project. � Demand for labour for digging the trenches where pipes will be laid, � Increased demand for food, drinks, and manufactured consumer products especially

telephone card from the construction workers.

Operation and Maintenance Phase

Social and Health Benefits: � Water would become available for the people in the areas thus distance to source of

water will be shortened � It will prevent or minimize time wastage by households in fetching water. � Reducing workload of households members, especially women, involved in fetching

water. In addition, � The incidence of water borne diseases especially diarrhea among children would be

reduced. This will help reduce child mortality. � General improvement in sanitation will also lead to a healthy environment.

National Development:

� The project will alleviate poverty, � It will enhance revenue generation of CRSG. � Improve economic well-being and health conditions of the people and will � Contribute to the attainment of the Millennium Development Goals (MDGs).

5.6 Potential Negative Impacts

An identification of potential impacts during the respective project phases is presented in tabular format in Table 5.8. Furthermore a rating of potential impacts is presented. It is noted that this rating is based on information that was gotten from the field survey. Impact significance has been categorized into three classes;

• Low • Medium • High

The criteria applied for the three classes are largely based on the expected magnitude of change caused by the project in combination with value/sensitivity of the receptor/resource.

5.7 Waste Water and Sludge Disposal

Sludge is to be treated and dried and be disposed in Local Authority registered landfill site for this purpose.



Sledges are classified according to the type of water treatment process adopted which may include: • Non-Chemical Sludge: derived from treatment plant using biological method such as

micro strainers,, pre-settlement unaided by chemicals, membrane backwash and sand washings from slow sand filters

• Coagulant sludge: arising from treatment plants using coagulation process. The treatment works for this water schemes project in Itigidi, Obubra and Okpoma employ coagulation, flocculation, clarification and filtration. In view of this, the projection of the quantities of dry solids in sludge produced area function of raw water quality and the chemical treatment being used. Generally, the sludge composition for this project consists of:

• Coagulant hydroxide • Suspended solids • Precipitated colour • Algae • Iron • Manganese • Powdered activated carbon • Impurities in lime and polyelectrolyte

Details of the types and sources of waste/sludge and applicable best treatment/disposal recommendations are contained as follows:

5.7.1 Estimation of the quantities of sludge

Estimation of the quantity of sludge for this project was made possible by estimating the quantity of raw water collection which is approximated by the quantity (m3/D) of water production. Water production on the other, is determined by any of the following:

a. Treatment plant capacity b. Daily water production (which is a function of water demand and water losses).

Daily water production estimate was applied in this study to approximate the amount of raw water intake, and shown as follows:

1. POLLUTION

(a) Air pollution

Air pollution will result from automobiles, light and heavy machines such as generators , and also from dusts being raised during clearing of bushes and felling of trees Burning of demolition and uprooted trees and grasses will also contribute to pollution.

Moderate

(b) Water pollution

Accidental spillage of fuel, lubricants and other chemicals may flow into surface waters leading to water pollution. Also project activities may lead to turbidity in surface watercourses due to run off of sediments resulting from increased erosion. Leaching of the fuels from the machines and automobiles into the underground water will result into water pollution.

Moderate

(c) Soil pollution

Soil pollution may occur as a result of accidental spillage of fuels such as diesel. In addition, there may be fuel, lubricants and other chemical leakages from improper storage facilities.

(d) Noise pollution Loud noise and vibrations may result from the use of equipment such as generators, vehicles, drilling machines (in the case of burrowing) etc.

Moderate

2. SOCIAL

(a) Safety of the public

Constructions sites, in particular, excavations as well as transportation, movement of heavy equipment and obstruction of roads may cause safety problems to the general public. The use of heavy equipment is expected to be limited. On the other hand, manually executed works will last longer, resulting in prolonged safety risks.

Furthermore, exposed trenches pose landslide hazards to humans and animals alike. The risk of such is common in the case of clearing works near frequented public buildings such as schools and religious centers.

Moderate

(b) Aesthetics

The aesthetics of the surroundings around the construction sites may be affected if not well managed. However, constructions in this project will take place in semi-urban and rural areas with moderate viewpoint sensitivity. Moreover, the impact is location specific and temporal.

Low

(c) Land take

The proposed construction of water intake tanks may result in the occupation of land used for other purposes (residential, agriculture, business etc), and which can possibly not be used as such after implementation of the works (e.g. because the ROW needs to be cleared of structures). The impact would be negligible, since most of the pipes will be laid along existing ROWs and all persons that could be affected by the project have been appropriately settled by the Cross River Sate Government.

(a) Public health

Given the tropical climate of Cross River State, stagnant water which may form in pits, holes, excavated ditches etc, at construction sites may create a habitat for insect disease vectors such as malaria, which poses a health concern to residents.

Moderate

(b) Health problems from construction camps and sites, and imported labour

In the case of badly managed construction camps and work sites public health problems may occur, although in this case it is not expected that large construction camps will be established, or that work sites will be large enough to cause important hazards to the general populace. Also, in view of the magnitude of works, the number of imported labourers may be quite low.

Low

(c) Occupational health and safety

Construction works such as: excavations; working with heavy equipment; working in confined spaces; working on and along the traffic roads; heavy lifting, storage, handling and use of dangerous substances and wastes, working under noisy conditions will expose the workers to occupational health and safety risks

Moderate

4. EROSION

(a) Soil erosion Water pipeline construction for the network extension and rehabilitation of water will entail clearance of the vegetation from site and the usage of heavy equipment for the work. The compaction of soil and loss of vegetation cover tends to accelerate erosion activity leading to secondary impacts such as soil instability, landslides in undulating landform and also surface water pollution due to runoff. Nevertheless most of the pipeline construction activities will take place along existing roads and not undulating landforms thereby reducing erosion impact to a minimum.

Moderate

5. FLORA AND FAUNA

(a) Impacts on flora and fauna

As the construction will require removal of natural vegetation for the proposed new pipeline extension which may lead to habitat destruction of natural existing fauna. Although most of the new pipeline extension work will occur along existing roads or ROWs with less bushes and shrubs removal making vegetation impact to be low due to low ecological value. Some economical tree will be affected

(a) Soil erosion and Contamination

The construction of the water distribution network (pipelines) requires the clearance of sites from vegetation, as well as the execution of excavation works using heavy equipments. Inappropriate construction practices and soil protection measures may induce or accelerate erosion, leading to soil instability and landslides in hilly areas, with possible water pollution due run-off to surface waters. Fortunately, the majority of construction which is related to pipe laying takes place along existing roads, and not on hill slopes. Nevertheless, it may be anticipated that the clearing of vegetation in the ROW will lead to temporary increase in soil erosion, until re-vegetation has occurred. Furthermore, contamination may occur as a result of accidental or structural spillage of fuels, lubricants chemicals, sanitary waste water, etc, as well as from leakages from inadequate protected solids waste storage facilities and sites. Good construction practices would however, largely avoid any such risks.

Moderate

Disturbance and interruption of commercial and social activities

Construction activities for the water distribution network may only be temporary, but construction activities may be spread over a long period of time. Without adequate planning and communication of activities, construction activities may cause traffic disruptions and congestion, resulting in temporary disturbance and interruption of commercial and social activities. This is particularly the case in the high density semi-urban environments. Construction activities may furthermore cause damage to other infrastructure (roads, sewerage pipes, drains, buildings etc.), and therewith lead to short-term disruption of certain public services.

In cases, excavated trenches may need to be kept dry through pumping out of ground water. The pumped water will need to be disposed off, but may be contaminated or high in suspended solids. Another issue related to water pollution is related to the fact that the extended distribution system will lead to increased water consumption and therewith wastewater production. This may, in turn, increase water pollution, since wastewater treatment facilities are in most cases absent. The impact is largely restricted to pipeline extensions.





2. SOCIAL

Nuisance and public health risks as a result of incidental and structural (institutional) operational failures of the distribution network

Piped water distribution systems are particularly sensitive to operational failures. Since drinking water is treated before entering the network and not at the actual distribution point in the houses, anything happening to the water in between will directly pose public health risks. Accidental ruptures of pipelines and structural degradation of pipelines as a result of ageing and poor maintenance, accompanied by low pressure in the pipes will allow the intrusion of potentially polluted groundwater into the drinking water distribution system. Another issue may be the realization of branched connections (e.g. for new areas or to households),if not done in a proper manner. Parts of such connections may be illegal. Particularly sensitive may be the impact in the case of or other areas of high level pollution such as landfills and industrial zones. Furthermore, accidents and leaks due to ruptures of pipelines may cause flooding with consequential effects, in particular in terms of disturbance of socio-economic activities. Flooding may also have its impact on insects and waterborne disease vectors, as well as public health risk due to overflowing of drainage systems and open sewers and is particularly hazardous in the vicinity of concentrated pollution sources such as landfills and industrial zones A third source of nuisance and public health risk is related to the fact that it may be expected that water consumption will increase as a result of the extended distribution system. Therewith, the production of wastewater will also increase. Since sanitary facilities in most areas are very basic, and centralized collection and treatment facilities do not exist, this may result in increased public health risks. In relative terms the increase in water production is not expected to be substantial, but local effects may be observed.

Loss of wild lands, forests and wildlife habitat.

The area of project activities is largely in the rural and semi-urban areas, and has consequently been greatly affected by human habitation. None of the project areas is of exceptional ecological value.

6 MITIGATION PLAN

6.1 Introduction

Environmental mitigation consists of measures that can reduce the negative environmental impacts associated with implementation (construction, expansion) of the project. Mitigation measures have been identified that would reduce both existing and potential impacts associated with existing facilities and upgrading/new construction.

For each of the identified impacts specific mitigation measures may be defined. The general rule in designing such measures is:

� Avoidance of major impacts: major impacts are generally considered unacceptable, certainly ones that

would endure into the long-term or extend over a large area; and

� Reduction of major and moderate impacts to as low as reasonably practicable by planning, designing and controlling mitigation measures. This Implies that mitigation measures will be applied up until the limitations of cost-effectiveness and practical application are reached. The limitations are established by best international practice.

� Implementation of good contractor practices for impacts rated as minor, in order to ensure that

impacts are management within good reason.

Table 6.1 Mitigation Hierarchy for Planned Project Activities

Avoid at Source; Reduce at Source Avoiding or reducing at source is essentially ‘designing’ the project so that a feature causing impact is designed out (e.g. pipeline re-route) or altered (e.g. reduced working width). Often called minimization. Abate on Site This involves adding something to the basic design to abate the impact- pollution controls fall within this

category. Often called end-of-pipe. Abate at Receptor If an impact cannot be abated on-site then measures can be implemented off-site. An example of this would be to instruct authorities in affected schools to increase the level of supervision of their pupils during the period of civil works. Repair or Remedy Some impacts involve unavoidable damage to a resource, e.g. agricultural land during pipeline construction. Repair essentially involves restoration and reinstatement type measures.

Mitigation measures related to construction of water treatment plants and extension of the distribution network.

5. FLORA AND FAUNA

(a) Impacts on flora and fauna � The Contractor should minimize the work site to the minimum possible size in an attempt to minimize the destruction on flora and fauna found and thus prevent ecological damages.

� The appropriate authority’s consent should be sought before any tree is fell. Also fees and fines should be paid where necessary to the appropriate institution.

� Ecological restoration through environmental engineering should be undertaken after any human intervention. This may include restoration of top soils and introduction of new species to restore the local ecology

6. WASTE MANAGEMENT � Collection and temporary storage of cleaning and sanitary wastes, as well as garbage, in containers. � The Contractor should prepare a Solid Waste Management Plan, which should include:

� A detailed list of the types and quantities of waste to be produced, including their hazard classes. � An assessment of any opportunities for reducing solid waste generation, in particular, hazardous and undesirable (persistent and non-re-

usable) types of wastes. � The most appropriate waste management plan should be determined for each type of solid waste. This should include details on

(temporary) storage, transport and a final destination for the waste. With regards to the latter, the most appropriate way would be reuse, followed by recycling/ recovery and finally disposal or incineration.

(a) Solid waste generation

� Records of types, quantities, origins, (temporary) storage, transport and elimination/ reuse of solid waste must be kept by the Contractor, and He/ She should make these available to the works supervisor upon his request, as proof of proper waste management practices.

� Waste disposals should occur at only site approved by the authorities. � Recycling companies should be used in transferring and, recycling and disposing of waste except for sludge that need to be recycled into the

water treatment systems. � Soils and underground waters should be taken into consideration when providing and constructing material storages.

(b) Sludge/ Waste water generation

� Sludge should be treated, and disposed off appropriately according to EPAD standards or re-used/recycled where feasible. Treated sludge/waste can also be economically useful for plant growth.

7. ENERGY CONSUMPTION

(c) Energy Consumption � Since the increase in energy consumption will not be substantial it is therefore advised that as much as possible the use of electrical power from PHCN be encouraged since it is more sustainable (cheaper and renewable) in place of diesel operated generators.

7 MONITORING PLAN

7.1 Monitoring Plan

The objective of the monitoring plan is to establish appropriate criteria to verify the predicted impact of the project, and to ensure that any unforeseen impacts are detected and the mitigation adjusted where needed at an early stage. The plan will ensure that mitigating measures are implemented during works: Specific objectives of the monitoring plan are to:

• check the effectiveness of recommended mitigation measures; • demonstrate that sub-project activities are carried out in accordance with the

prescribed mitigation measures and existing regulatory procedures; and • Provide early warning signals whenever an impact indicator approaches a

critical level. The oversight for the environmental and social management process of the sub-projects will be assured by the supervisory consultants in collaboration with the CRS-NUWSRP2 Project Implementation Unit via the Environmental Officer will be conducted during all phases of the project: design, construction, execution, operation and maintenance.

7.2 Monitoring Procedure:

A fundamental approach in monitoring and evaluation segment of this project will avoid the linear conceptual model, in which monitoring and evaluation come in the end of the implementation processes. However, it is recommended that monitoring will be a continuous process throughout the entire phases of the project.

Based on measurable indicators, the progress of the project will be assessed. The Environmental Officer will prepare a long term monitoring strategy that will encompass clear and definitive parameters to be monitored for each sub-project. The monitoring plan will take into consideration the scope of development, the environmental and social sensitivity and the financial and technical means available for monitoring. The plan will identify and describe the indicators to be used, the frequency of monitoring and the standard (baseline) against which the indicators will be measured for compliance with the EMP.

A number of indicators would be used in order to determine the status of the affected environment as follows: • Environmental Indicators:

o Loss of vegetation; o Land degradation; o Compliance with Legislations.

• Social indicators: o Population, o Income

8 ENVIRONMENTAL AND SOCIAL MANAGEMENT PLAN

8.1 Definition and Introduction

This involves environmental and social control and mitigation measures, monitoring programs, and responsibilities which must be developed based upon an assessment of environmental and social impacts and risks for the proposed project. This EMP is intended to ensure efficient environmental management of these activities. The EMP includes the following sections: • the potential environmental and social impacts, • the proposed mitigation measures, • arrangement for EMP implementation, • responsibilities for EMP and mitigation measures implementation; • capacity building needs; and • EMP implementation budget.

Summary of Impacts: The predicted adverse environmental and social impacts for which mitigation is required are identified and briefly summarised in tables 5.1 to 5.11.

Mitigation Measures: Feasible and cost effective measures to reduce potentially significant adverse environmental and social impacts to acceptable levels are defined. Details of the proposed mitigation measures can be found in Chapter 6.

Monitoring Measures: Activities to monitor the effectiveness of the defined mitigation measures are defined. These monitoring activities will allow for any additional remedial measures to be undertaken if mitigation measures are inadequate or the impacts have been underestimated within the EIA report, in particular where the results are not in compliance with the obtained permits, national standards and World Bank Group requirements and guidelines. Details of the proposed monitoring measures can be found in Chapter 7. Institutional Measures: Responsibilities for mitigation and monitoring will be clearly defined as well as arrangements for co-ordination between the various factors responsible for mitigation. Furthermore, training and capacity building requirement are presented. Implementation Schedule: The timing, frequency, and duration of mitigation measures are specified in an implementation schedule. Cost Estimates and Sources of Funds: For initial investment and recurring expenses for implementing of measures contained in the EMP, cost estimates are presented, in order to allow for integration into the total project costs.

Air pollution will result from automobiles, light and heavy machineries such as generators. and bulldozers Burning of wastes such as wood, paper etc. will also contribute to pollution. These pollution rates will also be minimal as construction would not be on a large scale and will be short term. As laying of the extension pipes will require the removal of the top soil i.e. digging in other to lay the pipes, there will be a substantial release of fine sand particles especially during the dry season, although this will be a short-termed impact since the removed earth will be replaced.

Operational failures are peculiar with piped water distribution system. Since drinking water is treated before entering the network and not at the actual distribution point in the houses (the traditional way), anything happening to the water in between will directly pose public health risks. Ruptures of pipelines and structural degradation of pipelines as a result of ageing and poor maintenance, accompanied by low pressure in pipes will allow the intrusion of potentially polluted groundwater into the drinking water distribution system. Another issue may be the realization of branched connections (e.g. for new area or to households), if not done in a proper manner. Part of such connections may be illegal. The impact in the case of ruptures in the vicinity of open or damaged sewers, the drainage system (often operating as an open sewer) or other areas of high level pollution such as landfills and industrial zones is particularly sensitive will pose a serious health risk to those who are supplied water from such network.

(i) Collection and temporary storage of cleaning and sanitary wastes, as well as garbage, in containers. (ii) The Contractor should prepare a Solid Waste Management Plan, which should include

+A detailed list of the types and quantities of waste to be produced, including their hazard classes. +An assessment of any opportunities for reducing solid waste generation, in particular of hazardous and undesirable (persistent and non-re-usable) types of wastes. +The most appropriate waste management plan should be determined for each type of solid waste. This should include details on (temporary) storage, transport and a final destination for the waste. With regards to the latter, the most appropriate way would be reuse, followed by recycling/ recovery and finally disposal or incineration. +How and by whom the waste management measures would be implemented Contractor or third party- specifying any such third party involvement.

(iii) Records of types, quantities, origins, (temporary) storage, transport and elimination/ reuse of solid waste must be kept by the Contractor, and He/ She should make these available to the works supervisor upon his request, as proof of proper waste management practices

9 PUBLIC CONSULTATION

9.1 Introduction

The consultation process and outcome was seen by the consultant as both an early and mandatory exercise in terms of the objective of project sustainability and as the best strategy to achieving the overall scope of the activities of the ESIA.

Consultation Strategy The Public Consultation process for the project began during the early stage of reconnaissance level-survey. The consultant, after familiarization meetings with the client (Cross River State Water Board Limited) requested for the contacts of all the area managers in the project areas. This was important not only to facilitate the reconnaissance survey of the project environment, but also to facilitate the process of meeting with other stakeholders. The consultant with the assistance of CRSWBL staff in the designated areas identified the stakeholders and they include:

• Community leaders, • Community associations; • Women Associations • Youths • Local Government Authorities, • Cross River State Water Board Limited.

A familiarization visitation was made to the various institutions and concerned stakeholders and the outcome were:

• Scheduling of meeting dates which was to incorporate a larger audience from the various stakeholders.

• Organization of locations for the public consultations.

Summary of the Public Consultations

The proceedings took the form of: • Introduction of the project to community members and stakeholders; • Informing them of the locations for the proposed installations/plants and the nature of the project; • Entertaining comments and questions from stakeholders, and • Addressing concerns raised by stakeholders.

The list of attendance at the public consultations is found in appendix 5, while Table 9.1 captures the summary of the proceedings and outcomes of the public consultations. It also provided comments/suggestions that may be suitable to the concerns raised and general observations made about the project areas.

Appendix 2: Summary of World Bank Environmental and Social Safeguard Policies

• Environmental Assessment (OP 4.01). Outlines Bank policy and procedure for the environmental assessment of Bank lending operations. The Bank undertakes environmental screening of each proposed project to determine the appropriate extent and type of EA process. This environmental process will apply to all CRS-NUWSRP 2 sub-projects.

• Natural Habitats (OP 4.04). The conservation of natural habitats, like other measures that protect and

enhance the environment, is essential for long-term sustainable development. The Bank does not support projects involving the significant conversion of natural habitats unless there are no feasible alternatives for the project and its siting, and comprehensive analysis demonstrates that overall benefits from the project substantially outweigh the environmental costs. If the environmental assessment indicates that a project would significantly convert or degrade natural habitats, the project includes mitigation measures acceptable to the Bank. Such mitigation measures include, as appropriate, minimizing habitat loss (e.g. strategic habitat retention and post-development restoration) and establishing and maintaining an ecologically similar protected area. The Bank accepts other forms of mitigation measures only when they are technically justified. Should the sub-project-specific EMPs indicate that natural habitats might be affected negatively by the proposed sub-project activities without suitable mitigation measures, such sub-projects will not be funded under the project.

• Pest Management (OP 4.09). The policy supports safe, affective, and environmentally sound pest

management. It promotes the use of biological and environmental control methods. An assessment is made of the capacity of the country’s regulatory framework and institutions to promote and support safe, effective, and environmentally sound pest management. This policy will most likely not apply to CRS-NUWSRP2 sub-projects.

• Involuntary Resettlement (OP 4.12). This policy covers direct economic and social impacts that both

result from Bank-assisted investment projects, and are caused by (a) the involuntary taking of land resulting in (i) relocation or loss of shelter; (ii) loss of assets or access to assets, or (iii) loss of income sources or means of livelihood, whether or not the affected persons must move to another location; or (b) the involuntary restriction of access to legally designated parks and protected areas resulting in adverse impacts on the livelihoods of the displaced persons. This policy will most likely not apply to the project, as it will not entail taking of land or restriction of access to sources of livelihood.

• Indigenous Peoples (OD 4.20). This directive provides guidance to ensure that indigenous peoples benefit from development projects, and to avoid or mitigate adverse effects of Bank-financed development projects on indigenous peoples. Measures to address issues pertaining to indigenous peoples must be based on the informed participation of the indigenous people themselves. Sub-projects that would have negative impacts on indigenous people will not be funded under CRS-NUWSRP2.

• Forests (OP 4.36). This policy applies to the following types of Bank-financed investment projects: (a)

projects that have or may have impacts on the health and quality of forests; (b) projects that affect the rights and welfare of people and their level of dependence upon or interaction with forests; and (c) projects that aim to bring about changes in the management, protection, or utilization of natural forests or plantations, whether they are publicly, privately, or communally owned. The Bank does not finance projects that, in its opinion, would involve significant conversion or degradation of critical forest areas or related critical habitats. If a project involves the significant conversion or degradation of natural forests or related natural habitats that the Bank determines are not critical, and the Bank determines that there are no feasible alternatives to the project and its siting, and comprehensive analysis demonstrates that overall benefits from the project substantially outweigh the environmental costs, the Bank may finance the project provided that it


.


132

incorporates appropriate mitigation measures. Sub-projects that are likely to have negative impacts on forests will not be funded under the project

• Cultural Property (OP 11.03). The term “cultural property” includes sites having archeological

(prehistoric), paleontological, historical, religious, and unique natural values. The Bank’s general policy regarding cultural property is to assist in their preservation, and to seek to avoid their elimination. Specifically, the Bank (i) normally declines to finance projects that will significantly damage non-replicable cultural property, and will assist only those projects that are sited or designed so as to prevent such damage; and (ii) will assist in the protection and enhancement of cultural properties encountered in Bank-financed projects, rather than leaving that protection to chance. The management of cultural property of a country is the responsibility of the government. The government’s attention should be drawn specifically to what is known about the cultural property aspects of the proposed project site and appropriate agencies, NGOs, or university departments should be consulted; if there are any questions concerning cultural property in the area, a brief reconnaissance survey should be undertaken in the field by a specialist.

• Safety of Dams (OP 4.37). For the life of any dam, the owner is responsible for ensuring that appropriate

measures are taken and sufficient resources provided for the safety to the dam, irrespective of its funding sources or construction status. The Bank distinguishes between small and large dams. Small dams are normally less than 15 m in height; this category includes, for example, farm ponds, local silt retention dams, and low embankment tanks. For small dams, generic dam safety measures designed by qualified engineers are usually adequate. This policy does apply to the project and the mitigatory measures via the preparation of a dam safety status report have already been undertaken.

• Projects on International Waterways (O 7.50). The Bank recognizes that the cooperation and good will

of riparian is essential for the efficient utilization and protection of international waterways and attaches great importance to riparian making appropriate agreements or arrangement for the entire waterway or any part thereof. Projects that trigger this policy include hydroelectric, irrigation, flood control, navigation, drainage, water and sewerage, industrial, and similar projects that involve the use or potential pollution of international waterways. This policy will not apply to the project.

• Disputed Areas (OP/BP/GP 7.60). Project in disputed areas may occur between the Bank and its

member countries as well as between the borrower and one or more neighbouring countries. Any dispute over an area in which a proposed project is located requires formal procedures at the earliest possible stage. The Bank attempts to acquire assurance that it may proceed with a project in a disputed area if the governments concerned agree that, pending the settlement of the dispute, the project proposed can go forward without prejudice to the claims of the country having a dispute. This policy is not expected to be triggered by CRS-NUSRP2 sub-projects.

Appendix 4: Construction Contracts Environmental Management Conditions

General

1. In addition to these general conditions, the Contractor shall comply with any specific Environmental Management Plan (EMP) or Environmental and Social Management Plan (ESMP) for the works he is responsible for. The Contractor shall inform himself about such an EMP, and prepare his work strategy and plan to fully take into account relevant provisions of that EMP. If the Contractor fails to implement the approved EMP after written instruction by the Supervising Engineer (SE) to fulfill his obligation within the requested time, the Owner reserves the right to arrange through the SE for execution of the missing action by a third party on account of the Contractor.

2. Notwithstanding the Contractor’s obligation under the above clause, the Contractor shall implement all measures

necessary to avoid undesirable adverse environmental and social impacts wherever possible, restore work sites to acceptable standards, and abide by any environmental performance requirements specified in an EMP. In general these measures shall include but not be limited to:

(a) Minimize the effect of dust on the surrounding environment resulting from earth mixing sites, asphalt mixing sites, dispersing coal ashes, vibrating equipment, temporary access roads, etc. to ensure safety, health and the protection of workers and communities living in the vicinity of dust producing activities.

(b) Ensure that noise levels emanating from machinery, vehicles and noisy construction activities (e.g. excavation, blasting) are kept at a minimum for the safety, health and protection of workers within the vicinity of high noise levels and nearby communities. (c) Ensure that existing water flow regimes in rivers, streams and other natural or irrigation channels is maintained and/or re-established where they are disrupted due to works being carried out. (d) Prevent bitumen, oils, lubricants and waste water used or produced during the execution of works from entering into rivers, streams, irrigation channels and other natural water bodies/reservoirs, and also ensure that stagnant water in uncovered borrow pits is treated in the best way to avoid creating possible breeding grounds for mosquitoes. (e) Prevent and minimize the impacts of quarrying, earth borrowing, piling and building of temporary construction camps and access roads on the biophysical environment including protected areas and arable lands; local communities and their settlements. In as much as possible restore/rehabilitate all sites to acceptable standards. (f) Upon discovery of ancient heritage, relics or anything that might or believed to be of archeological or historical importance during the execution of works, immediately report such findings to the SE so that the appropriate authorities may be expeditiously contacted for fulfillment of the measures aimed at protecting such historical or archaeological resources.

(g) Discourage construction workers from engaging in the exploitation of natural resources such as hunting, fishing, and collection of forest products or any other activity that might have a negative impact on the social and economic welfare of the local communities.

(h) Implement soil erosion control measures in order to avoid surface run off and prevents siltation, etc.

(i) Ensure that garbage, sanitation and drinking water facilities are provided in construction workers camps.

(j) Ensure that, in as much as possible, local materials are used to avoid importation of foreign material and long distance transportation.



138

(k) Ensure public safety, and meet traffic safety requirements for the operation of work to avoid accidents.

3. The Contractor shall indicate the period within which he/she shall maintain status on site after completion of civil

works to ensure that significant adverse impacts arising from such works have been appropriately addressed. 4. The Contractor shall adhere to the proposed activity implementation schedule and the monitoring plan / strategy

to ensure effective feedback of monitoring information to project management so that impact management can be implemented properly, and if necessary, adapt to changing and unforeseen conditions.

5. Besides the regular inspection of the sites by the Supervising Engineer for adherence to the contract conditions

and specifications, the Owner may appoint an Inspector to oversee the compliance with these environmental conditions and any proposed mitigation measures. State environmental authorities may carry out similar inspection duties. In all cases, as directed by the SE, the Contractor shall comply with directives from such inspectors to implement measures required to ensure the adequacy rehabilitation measures carried out on the bio-physical environment and compensation for socio-economic disruption resulting from implementation of any works.

Worksite/Campsite Waste Management 6. All vessels (drums, containers, bags, etc.) containing oil/fuel/surfacing materials and other hazardous chemicals

shall be bonded in order to contain spillage. All waste containers, litter and any other waste generated during the construction shall be collected and disposed off at designated disposal sites in line with applicable government waste management regulations.

7. All drainage and effluent from storage areas, workshops and camp sites shall be captured and treated before being

discharged into the drainage system in line with applicable government water pollution control regulations. 8. Used oil from maintenance shall be collected and disposed off appropriately at designated sites or be re-used or

sold for re-use locally. 9. Entry of runoff to the site shall be restricted by constructing diversion channels or holding structures such as

banks, drains, dams, etc. to reduce the potential of soil erosion and water pollution. 10. Construction waste shall not be left in stockpiles along the road, but removed and reused or disposed of on a

daily basis. 11. If disposal sites for clean spoil are necessary, they shall be located in areas, approved by the SE, of low land use

value and where they will not result in material being easily washed into drainage channels. Whenever possible, spoil materials should be placed in low-lying areas and should be compacted and planted with species indigenous to the locality.

Material Excavation and Deposit 12. The Contractor shall obtain appropriate licenses/permits from relevant authorities to operate quarries or borrow

areas. 13. The location of quarries and borrow areas shall be subject to approval by relevant local and national authorities,

including traditional authorities if the land on which the quarry or borrow areas fall in traditional land. 14. New extraction sites:



139

a) Shall not be located in the vicinity of settlement areas, cultural sites, wetlands or any other valued ecosystem component, or on high or steep ground or in areas of high scenic value, and shall not be located less than 1km from such areas.

b) Shall not be located adjacent to stream channels wherever possible to avoid siltation of river channels. Where they are located near water sources, borrow pits and perimeter drains shall surround quarry sites.

c) Shall not be located in archaeological areas. Excavations in the vicinity of such areas shall proceed with great care and shall be done in the presence of government authorities having a mandate for their protection.

d) Shall not be located in forest reserves. However, where there are no other alternatives, permission shall be obtained from the appropriate authorities and an environmental impact study shall be conducted.

e) Shall be easily rehabilitated. Areas with minimal vegetation cover such as flat and bare ground, or areas covered with grass only or covered with shrubs less than 1.5m in height, are preferred.

f) Shall have clearly demarcated and marked boundaries to minimize vegetation clearing.

15. Vegetation clearing shall be restricted to the area required for safe operation of construction work. Vegetation

clearing shall not be done more than two months in advance of operations. 16. Stockpile areas shall be located in areas where trees can act as buffers to prevent dust pollution. Perimeter drains

shall be built around stockpile areas. Sediment and other pollutant traps shall be located at drainage exits from workings.

17. The Contractor shall deposit any excess material in accordance with the principles of these general conditions,

and any applicable EMP, in areas approved by local authorities and/or the SE. 18. Areas for depositing hazardous materials such as contaminated liquid and solid materials shall be approved by the

SE and appropriate local and/or national authorities before the commencement of work. Use of existing, approved sites shall be preferred over the establishment of new sites.

Rehabilitation and Soil Erosion Prevention 19. To the extent practicable, the Contractor shall rehabilitate the site progressively so that the rate of rehabilitation

is similar to the rate of construction. 20. Always remove and retain topsoil for subsequent rehabilitation. Soils shall not be stripped when they are wet as

this can lead to soil compaction and loss of structure. 21. Topsoil shall not be stored in large heaps. Low mounds of no more than 1 to 2m high are recommended. 22. Revegetate stockpiles to protect the soil from erosion, discourage weeds and maintain an active population of

beneficial soil microbes. 23. Locate stockpiles where they will not be disturbed by future construction activities. 24. To the extent practicable, reinstate natural drainage patterns where they have been altered or impaired. 25. Remove toxic materials and dispose of them in designated sites. Backfill excavated areas with soils or

overburden that is free of foreign material that could pollute groundwater and soil.



140

26. Identify potentially toxic overburden and screen with suitable material to prevent mobilization of toxins. 27. Ensure reshaped land is formed so as to be inherently stable, adequately drained and suitable for the desired

long-term land use, and allow natural regeneration of vegetation. 28. Minimize the long-term visual impact by creating landforms that are compatible with the adjacent landscape. 29. Minimize erosion by wind and water both during and after the process of reinstatement. 30. Compacted surfaces shall be deep ripped to relieve compaction unless subsurface conditions dictate otherwise. 31. Revegetate with plant species that will control erosion, provide vegetative diversity and, through succession,

contribute to a resilient ecosystem. The choice of plant species for rehabilitation shall be done in consultation with local research institutions, forest department and the local people.

Water Resources Management 32. The Contractor shall at all costs avoid conflicting with water demands of local communities. 33. Abstraction of both surface and underground water shall only be done with the consultation of the local

community and after obtaining a permit from the relevant Water Authority. 34. Abstraction of water from wetlands shall be avoided. Where necessary, authority has to be obtained from

relevant authorities. 35. Temporary damming of streams and rivers shall be done in such a way avoids disrupting water supplies to

communities down stream, and maintains the ecological balance of the river system. 36. No construction water containing spoils or site effluent, especially cement and oil, shall be allowed to flow into

natural water drainage courses. 37. Wash water from washing out of equipment shall not be discharged into water courses or road drains. 38. Site spoils and temporary stockpiles shall be located away from the drainage system, and surface run off shall be

directed away from stockpiles to prevent erosion.

Traffic Management

43. Blasting activities shall be done during working hours, and local communities shall be consulted on the proposed

blasting times.



141

44. Noise levels reaching the communities from blasting activities shall not exceed 90 decibels.

Disposal of Unusable Elements

45. Unusable materials and construction elements such as electro-mechanical equipment, pipes, accessories and demolished structures will be disposed of in a manner approved by the SE. The Contractor has to agree with the SE which elements are to be surrendered to the Client’s premises, which will be recycled or reused, and which will be disposed of at approved landfill sites.

46. As far as possible, abandoned pipelines shall remain in place. Where for any reason no alternative alignment for

the new pipeline is possible, the old pipes shall be safely removed and stored at a safe place to be agreed upon with the SE and the local authorities concerned.

47. AC-pipes as well as broken parts thereof have to be treated as hazardous material and disposed of as specified

above. 48. Unsuitable and demolished elements shall be dismantled to a size fitting on ordinary trucks for transport.

Repair of Private Property

52. Should the Contractor, deliberately or accidentally, damage private property, he shall repair the property to the owner’s satisfaction and at his own cost. For each repair, the Contractor shall obtain from the owner a certificate that the damage has been made good satisfactorily in order to indemnify the Client from subsequent claims.

53. In cases where compensation for inconveniences, damage of crops etc. are claimed by the owner, the Client has

to be informed by the Contractor through the SE. This compensation is in general settled under the responsibility of the Client before signing the Contract. In unforeseeable cases, the respective administrative entities of the Client will take care of compensation

Contractor’s Health, Safety and Environment Management Plan (HSE-MP)

54. Within 6 weeks of signing the Contract, the Contractor shall prepare an EHS-MP to ensure the adequate management of the health, safety, environmental and social aspects of the works, including implementation of the requirements of these general conditions and any specific requirements of an EMP for the works. The Contractor’s EHS-MP will serve two main purposes: • For the Contractor, for internal purposes, to ensure that all measures are in place for adequate HSE

management, and as an operational manual for his staff. • For the Client, supported where necessary by a SE, to ensure that the Contractor is fully prepared for the

adequate management of the HSE aspects of the project, and as a basis for monitoring of the Contractor’s HSE performance.

55. The Contractor’s EHS-MP shall provide at least:

• a description of procedures and methods for complying with these general environmental management



142

conditions, and any specific conditions specified in an EMP; • a description of specific mitigation measures that will be implemented in order to minimize adverse impacts; • a description of all planned monitoring activities (e.g. sediment discharges from borrow areas) and the

reporting thereof; and • the internal organizational, management and reporting mechanisms put in place for such.

56. The Contractor’s EHS-MP will be reviewed and approved by the Client before start of the works. This review

should demonstrate if the Contractor’s EHS-MP covers all of the identified impacts, and has defined appropriate measures to counteract any potential impacts.

HSE Reporting

57. The Contractor shall prepare bi-weekly progress reports to the SE on compliance with these general conditions, the project EMP if any, and his own EHS-MP. An example format for a Contractor HSE report is given below. It is expected that the Contractor’s reports will include information on: • HSE management actions/measures taken, including approvals sought from local or national authorities; • Problems encountered in relation to HSE aspects (incidents, including delays, cost consequences, etc. as a

result thereof); • Lack of compliance with contract requirements on the part of the Contractor; • Changes of assumptions, conditions, measures, designs and actual works in relation to HSE aspects; and

• Observations, concerns raised and/or decisions taken with regard to HSE management during site meetings.

58. It is advisable that reporting of significant HSE incidents be done “as soon as practicable”. Such incident reporting shall therefore be done individually. Also, it is advisable that the Contractor keeps his own records on health, safety and welfare of persons, and damage to property. It is advisable to include such records, as well as copies of incident reports, as appendices to the bi-weekly reports. Example formats for an incident notification and detailed report are given below. Details of HSE performance will be reported to the Client through the SE’s reports to the Client.

Training of Contractor’s Personnel

59. The Contractor shall provide sufficient training to his own personnel to ensure that they are all aware of the relevant aspects of these general conditions, any project EMP, and his own EHS-MP, and are able to fulfill their expected roles and functions. Specific training should be provided to those employees that have particular responsibilities associated with the implementation of the EHS-MP. General topics should be: • HSE in general (working procedures); • emergency procedures; and • social and cultural aspects (awareness raising on social issues).

Cost of Compliance

60. It is expected that compliance with these conditions is already part of standard good workmanship and state of the art as generally required under this Contract. The item “Compliance with Environmental Management Conditions” in the Bill of Quantities covers these costs. No other payments will be made to the Contractor for compliance with any request to avoid and/or mitigate an avoidable HSE impact.

Appendix 8: Development of a Waste Management Plan

1.0. Background

Liquid waste is normally discharged from base-exchange softening plants, which are regenerated with brine. On the other hand, sludge waste is a highly concentrated suspension of solids in liquid. Tens of thousands of tons of waste water & sludge waste are generated annually from water treatment plants. Best management practices are essential for sludge wastes since these materials could be hazardous to human and environment. These practices include careful considerations of conditions for storage and treatment of the wastes. Storage condition is especially important in situation when immediate treatment of the wastes is not feasible. It is the goal of every waste water/sludge waste management plan to embark upon measures that re-use this waste whenever possible and embrace a disposal routes that shall minimize the adverse effects, on the environment. Waste water/Sludge Wastes Management Plan, is condition specific and takes cognizance of the chemical, physical, and biological characteristics of the wastes and it should tell you the following:

• Pollution potential of the sludge/wastes with respect to local environmental conditions

• Options for recovery of water from sludge

• Appropriate methods for storage and required storage conditions

• Competing options for stabilizing the sludge

• Types of bulking agent(s) to use

• How to prevent contamination of the environment by sludge leachate

• Factors to consider with respect to future treatment method

• Transportation planning when necessary

• Appropriate treatments options

• Sludge recycling options

2.0 Plans for Waste Water/Sludge Management

This plan for waste water sludge management shall be guided by the following steps:

• Collect baseline data on waste water/sludge waste properties



156

• Evaluate local regulations on sludge

• Construction of sludge processing facilities • Disposal

• Training Needs

• Interface with EMP in implementation

• Recycle Options

2.1. Baseline Assessment of Waste Water/Sludge Properties

A proper baseline assessment would need to be undertaken to gather precise information on the sludge/wastes, generated by this water treatment plant with the purpose of analyzing the liquid wastes and Sludge. The following baseline data will be collected and analyzed: • Composition types (Contained in table.1.) • chemical • physical • biological • Physiochemical quality of surface and underground water • Liquid waste Available data indicates Liquid waste is normally discharged from base-exchange softening plants, which are regenerated with brine. On the average about six percent (6%) of the total throughput of the plant is discharged to waste. The main pollutants are the chlorides and calcium and magnesium, in concentrations of about 20, 000mg L -1 Such effluents can generally be discharged into town sewers. They are difficult to treat and where they arise in inland sites, in arid countries, care should be taken to prevent polluting surface or underground sources.

• Sludge The basic composition of sludge at the Ikom, Ogoja and Obudu Water Supply Schemes project sites is contained in Table.5.10. of the EMP document, where the impact assessment and mitigation measures have been carefully undertaken to reveal that the sludge contains chemicals such as micro-organisms, arsenics and other metals, radio nuclides, lime and polymers, and this kind of sludge is consistent with the major portion of the effluent from a river abstraction. The total daily volume of sludge is normally in the range of 1.5 – 5.0% of the daily plant throughput.

2.2. Determine Local Regulations on Waste Water/Sludge Waste



157

To ensure sludge management practices are as in compliance with legislation, this plan would review relevant statutory documentation such as that of FEPA Acts 58 of 1988 and 59 of 1992, for conformity. Also, the Federal Ministry of Environment has put in place statutory documents to aid the monitoring, control and abatement of industrial waste that clearly state the restrictions imposed on the release of toxic substances into the environment and the responsibilities of all industries whose operations are likely to pollute the environment. Mitigation measures and monitoring impact have given due and necessary considerations to these statutory regulations in Table.9.3 (EMP document). • Such responsibilities include adequate treatment of effluent before being discharged into

the environment. 2.3. Construction of Sludge Storage/Processing Facility

The construction of a waste water/sludge storage processing plant (budget in appendix) will be discussed under the following:

• Waste water Treatment • Sludge water treatment • Effluent outfalls • Sewage Collection • Disposal Waste water Treatment For the waste water/sludge treatment plant for IItigidi, Obubra & Okpoma Water Distribution & Supply Schemes, treatment methods to be considered would include: • Activated sludge • Oxidation ditch • Bio-disc • Oxidation ponds At this stage, from experience, no single particular method can be adopted. This is because factors such as the composition of sewage, climate, groundwater and rainfall intensity and pattern may well influence the type to be selected.

Sludge Treatment Surface and ground waters undergo water treatment procedures in order to make them suitable for human consumption. Currently in some parts of the Europe, aluminium sulphate salt (alum) is used in a number of the Water Treatment plants for the treatment of surface and ground waters for drinking purposes. Treatment options used include sand filtration and or clarification with chemical coagulants and flocculants. The sludge generated from clarification procedures vary in type and quantity depending on the treatment methods used and the type and quality of the raw water abstracted.

Water treatment sludge are classified as a waste and therefore must be managed and disposed of appropriately.

2.4. Collection and Disposal

The handling and disposal of sludge is still a major challenge on several water treatment plants. Mitigation of impact with attendant costs is contained in table.9.3. Of the EMP document.

Federal Environmental Protection laws are currently being reviewed in the developing countries to curtail the erstwhile adopted practice of discharging untreated sludge back into the system (Sonuga and Oloke 1999). However, a range of choices are available, which shall be guided by Best Practice Environmental Options (BPEO) such as:

• Direct disposal into the river • Discharge into sewer • Lagooning • Concentration and drying – use of concentration tanks and drying beds. The sludge is

discharged to secondary fill and draw settling basins. The capacity of each tank would be about 200m3 in a 10,000m3 day -1 works.

• Modern techniques – usually practiced in developing countries involve vacuum filtration, centrifuging, freezing and filter pressing, precipitation and softening. However, this approach is usually expensive.

Disposal method adopted shall be in line with EPAD standards.

2.5. Training Needs

Based on assessment of institutional capacities, the EMP has identified that there is a need to train the PIU and other agencies involved in the EMP implementation. This responsibility is for action, by the Cross River Water Board Limited. This plan would therefore include training needs that shall support the waste water and sludge management plan. Course plan and corresponding costs are included in Table.9.1. (EMP document).

2.6. Interface with EMP

The waste water/sludge waste management issues are a component of the various activities that have undergone assessment under the Environmental management plan (EMP) and therefore possess an interface relationship with this plan. Implementation, Budgeting and Responsibility considerations will also be reviewed in this regard.

2.7. Recycle Option

The treatment and disposal of sludge will become an increasing environmental and financial issue as sludge production continues to increase as new Waste Water Treatment, and Water Treatment facilities are constructed and sludge quality standards become more stringent. The preferred option for dealing with sludge would be by recycling or use of sludge, as opposed to land-filling or incineration.

The composting of wastewater plant sludge appears to be the best option against other ways of elimination/disposal; this way they wouldn’t be such an economical and sanitary problem because the sludge would be recycled. Some techniques of recycling suppose a complex technological infrastructure, and a considerable energetic costs, but the agricultural reuse is justifiable by many and very important reasons; the cultivations nowadays and in this latitudes need a great amount of nutrients and they have to be replace periodically by fertilizing, without them the mechanical, physical and chemical properties of the soil would decrease, troubling the vegetal growth and affecting directly in the quality and quantity of the crops; fertilizing has become a main step in the agricultural activity and it use to be done with chemical fertilizers and with dung; because of that there is a good chance of using the sludge as a fertilizer and at the same time revalue this wastes. Not all the raw materials are suitable for the process; for example, it’s better to use sludge from urban water-treatment plants, avoiding this way contents of heavy metals and other inappropriate products inadequate for the agricultural use. With this objective of an agricultural use, the sludge must be processed to reduce the humidity, increase the ratio C/N, change the physical structure and decrease the presence of pathogen micro organisms

3.0 Conclusion and Recommendations

Environmental impacts and aspects of the waste water and sludge treatment plant, reviewed in line with the resource consumption, legal requirements and potential impact, from the Environmental Management Plan (EMP), is significant.

Thus, for efficiency and effectiveness of environmental management best practise, we would recommend that a waste water and sludge processing plant facility be constructed, separate from the water processing plant, which will operate in compliance with ISO standards. This would allow establishment of specific controls to enable implementation of these mitigation measures, in conformity with legislation, which would be audited regularly for on-track assessment. Furthermore, regarding re-cycle considerations, sludge from the various components of the sewage treatment can be digested and then dried on sludge drying beds, whereby the gas produced by the digestion of sludge can easily be used for alternative energy sources and the residual solid, through a proper nutrient management plan, can be integrated into agricultural/horticultural schemes.
