INTRODUCTION
1.1 Background
The Urban Water and Sanitation Improvement and Expansion Project (UWSIEP)contributes to the Government of Indonesia's objective of improving the qualityof water and sanitation services in Indonesia. It will help to establish andconsolidate viable local water utilities, expand wastewater collection in urbanareas and establish a regulatory entity and framework for on-lending to the watersector. Consequently there are three project components: a water component;sanitation component; and technical assistance component.
1.2 Objectives
The Government of Indonesia requires all projects to be 'screened' in order todetermine potential levels of environmental impact, and for suitable measures toaddress these impacts to be designed in, as necessary. The World Bank alsoapplies its own safeguard policies to all projects.
This document provides an environmental management framework for proposedactivities associated with the sanitation component of UWSIEP. Environmentalissues associated with the water component are covered under a separatedocument - "Consolidated Environmental Management Plan".
The separation of these two documents recognises that the sanitation componentfollows a community-based approach, and that decisions regarding location andscale of sanitation options are, as yet, undecided.
1.3 Environmental Screening Category
USWIEP has been classified as a Bank environmental "Category B" project.Consequently no projects with the potential to cause significant adverseenvironmental impacts (Category A) will be approved. Table 3 summarises theBank's environmental screening categories and related Government of Indonesiaenvironmental requirements.

II PROJECT DESCRIPTION
2.1 The Sanitation Component
The sanitation component will develop strategies for citywide sanitation and pilottest community based approaches to sanitation services in 12 small communitiesacross three urban centres. Community schemes will be based on the Water andSanitation Programme "SANIMAS" approach.
2.2 The SANIMAS Concept
SANIMAS is a Community-Based Sanitation (CBS) Program, the objective beingto improve individual sanitary facilities and related habits for low-income urbancommunities. Sanitary facilities in many urban areas in Indonesia can be found asseptic tanks with or without proper seepage area; while in slum areas, there isfrequently nothing at all.
Contrary to the Clean/Drinking Water Programs, people are not interested insanitary programs, because the benefit can not be felt directly, even if waste wateris hazardous to health. This fact only points to the inadequate health knowledge ofthe community. The SANIMAS approach therefore applies the followingprinciples:
* health education,* attractive program which increases income/benefit, and* participatory approach.
Additional income can be obtained from participation in SANIMAS, e.g., toprovide opportunities for the community to conduct aquatic culture. Sludgetreatment can be done in such away that it will benefit the community, sincedomestic waste is in fact full of potential resources. It need only be treated tomake it safe to handle. The required construction skill is also very important tomake them able to maintain, operate, and replicate the systems by themselves.Replication being a measure of a success of a participative program.
The participation aspect of the project is the key to success. Communityparticipation should start from the education process, selection of technology,planning, preparation, construction, operation, maintenance, and managementstages.

2.3 Implementation Arrangements
Existing guidance on SANIMAS implementation identifies the following steps:
* Preparation of implementation options* Selection of municipalities* Selection of communities* Finalising community action plan* Implementation of community based sanitation* Evaluation.
Once communities have been selected, a two phase planning and implementationprocess is envisaged, as follows:
* improvement of household sanitation facilities,- participative health education to motivate the community to participate
in the program- self-survey to get data on environmental support system, demography,
and health conditions- sanitation technology selection together with the community- community involvement in construction, such that they acquire
knowledge and skill in sanitation facilities construction, maintenanceand operation.
* establishment of sludge treatment and disposal system,- selection of treatment technology- selection of location- cost benefit analysis (technical, social, environmental and financial)- permitting and support from local officials (including environmental
clearance)- construction, operation, maintenance, management and monitoring.
III PROCEDURES FOR ENVIRONMENTAL REVIEW
3.1 Regulatory context
Applicable environmental regulations and policies in determining potential levelof impact and necessary management response include:
* World Bank: Environmental Assessment (OP/BP/GP 4.01)* World Bank: Pollution Prevention and Abatement Handbook, 1998.
General Environmental Guidelines (see Attachment B)* Government of Indonesia Law no. 23/1997 concerning Environmental
Management
5
* Government of Indonesia Regulation (Peraturan Pemerintah, or PP) no.27/1999 concerning AMDAL
* Decree of the State Minister of the Environment No. 17/2001 concerningTypes of Activities which should be accompanied by AMDAL (seeAttachment A)
* Decree of the Ministry of Settlement and Regional Infrastructure No.17/2003 on Types of Activities which should be accompanied byUKIJ/UPL (see Attachment A)
* Decree of the State Minister of the Environment No. 86/2002 concerningGuidance for the Preparation of UKIJUPL
* Decree of the State Minister of the Environment No. 112/2003 on effluentquality standards
* Decree of the Ministry of Settlement and Regional Infrastructure No.534/2001 on guidance for minimum service standards on spatial planning,housing, settlement and public works (see Attachment C).
The Ministry of Settlements and Regional Infrastructure also routinely appliesStandard Operating Procedures associated with contracts issued for constructionpurposes. SOPs cover a range of onsite management, health, safety andenvironmental management requirements. It is the responsibility of the contractorto ensure compliance with these requirements.
3.2 Potential environmental impacts
The sanitation component seeks to address critical environmental and publichealth concerns. Indonesia has one of the lowest rates of urban seweragecoverage in Asia leading to widespread contamination of surface andgroundwater, as well as high incidence of environmentally attributable disease. Inthis sense, the sanitation component is clearly 'environmental' in its approach andobjectives.
However, it is also recognised that sanitation options themselves, ifinappropriately designed or located, may lead to significant (albeit localised)impacts. Therefore proposed options must be designed to meet applicableenvironmental standards relating to safe disposal/discharge of residues, and thenmanaged to achieve these standards. Key areas of concern1 include:
resulting from collection systems,* public health hazards from sewer overflows and backups;
resulting from treatment systems,
A useful summary of potential environmental impacts associated with sanitation programs is provided inthe Bank's 1991 Environmental Assessment Source Book (Volume II: Wastewater Collection, Treatment,Reuse and Disposal Systems).
6
* degradation of neighbourhoods or receiving water quality from treatmentwork by-passes, or treatment process failures;
* degradation of receiving water quality, despite normal system operation,from inappropriate siting and design;
resulting from disposal systems,* soil and groundwater contamination and disease vector breeding at sludge
storage, reuse or disposal sites;* existing solid waste management problems exacerbated by sludge
disposal.
These issues are made particularly acute where water quality problems are alreadysevere and in densely populated areas.
3.3 Environmental review process
The environmental review process for sanitation sub-projects will be closelylinked to the SANIMAS decision making process (see Table 3), and will includethe following steps:
* Environmental screening in accordance with LH KepMen 17/2001 andKimpraswil KepMen 17/2003; following section of technology and siteselection.
* Where required, completion of draft UKLIUPL in line with LH KepMen86/2002; in parallel with cost benefit analysis.
* Review and approval of UKL/UPL, ensuring that design specificationsmeet all relevant environmental standards2 in relation to siting anddischarges; prior to issuance of principal permit.
* Implementation of UKL/UPL recommendations and Standard OperatingProcedures; during construction and operational phase.

IV ENVIRONMENTAL MITIGATION AND MONITORING
4.1 Mitigation and Monitoring
Community-based sanitation systems generally comprise the followingcomponents: toilets; collection systems; treatment systems; disposal; andoperation & maintenance. Their environmental impacts are well known as arerelated mitigation and monitoring requirements.
Environmental impacts tend to accumulate at or around points of discharge/disposal, providing a focus for monitoring efforts. Mitigation measures can beapplied across all components, though key opportunities generally relate to designand siting of treatment and disposal systems.
Table 4 provides a framework for identifying suitable mitigation and monitoringmeasures, based on a range of design options available under SANIMAS. Thistable will be further developed based on the proposed study of lessons learnedfrom SANIMAS (see section 4.2).

Implementation of mitigation and monitoring measures will primarily be theresponsibility of the community, while monitoring responsibilities will be sharedwith the local environmental office. Typically, the community will be responsiblefor non-technical monitoring while the local environmental office will carry outdischarge monitoring of raw water and treated water.
4.2 Lessons Learned from SANIMAS in Indonesia
SANIMAS is a system that has been implemented in Indonesia under the Waterand Sanitation Programme. Experience to date is positive with communitiescontinuing to manage the systems, while local authorities are responsible formonitoring performance and providing technical advice.
Lessons learned both from communities and local authorities will be collated andintegrated into an operational guideline (based on Table 4) to assist preparation ofproposed community based sanitation options under UWSIEP. The centralProject Coordinating Unit will be responsible for ensuring that these measures aretaken.
4.3 Evaluation
A review of the environmental performance of selected CBS schemes will beundertaken as part of routine project evaluation, with participation both from localcommunities and local environmental authorities. As a pilot scheme, it isimportant that the results of environmental review are disseminated and caneffectively feed into the process of replication in other urban areas in Indonesia.Effective environmental compliance will ensure the long term sustainability of theSANIMAS approach and help to address critical human health concerns.

Attachment C: Excerpts from Decree of the Ministry of Settlement andRegional Infrastructure No. 534/2001 on guidance for minimum servicestandards on spatial planning, housing, settlement and public works(including waste water and sanitation).
The Decree contains the following guidance:
- Grey water should be separated from black water- Black water should be discharged into a septic tank with no leaks or smell- There should be no contamination of ground water- Removal efficiencies for BOD and SS > 85%- No complaint on sludge treated in sludge treatment plant
On site sanitation should be provided to cities with population density of 2 200persons/ha, with groundwater level >2 meter and its potential cost recovery is notsupporting full sewerage system
Off site sanitation could only be implemented in the metropolitan city with a density of 2200 persons/ha, groundwater level <2 meter, where potential cost recovery is notsupporting a full sewerage system with sewer network and wastewater treatment plant.
The quality of the facility should not have blockage, removal of BOD and SS inWastewater treatment plant > 90%, and Escherichia coli >+99.9%.
