1. Background information
In September 2019, China Communications and Construction Company Limited (CCCC)
prepared and submitted to KPA an Environmental Management and Monitoring Plan (EMMP)
as well as a Baseline Environmental Monitoring Report for the new Kipevu Oil Terminal
(KOT) Pipeline Marshalling Yard at Dongo Kundu Special Economic Zone (SEZ). Afterwards
CCCC engaged Envasses Environmental Consultants Limited, a Firm of Experts registered by
NEMA and Polucon Services (K) Limited who are a gazetted testing laboratory by NEMA to
implement the EMMP. Between October and November 2019, a total of five (5) weekly
monitoring reports were prepared consistent with the schedule agreed upon between CCCC,
KPA, NEMA and the consultants. It had been previously agreed among the stakeholders that
the reporting frequency would be reviewed with time as informed by the weekly reports and
findings of the monitoring activities. This was done in November when KPA communicated
to CCCC that the monitoring reports can be prepared and submitted on a monthly basis for
the remaining part of their contract.
This is therefore the eighth monthly report covering the period between 1st – 30
th April 2021
on implementation of the EMMP for the new KOT Pipeline Marshalling Yard at Dongo
Kundu SEZ. The main activities of the project include excavations and levelling of the yard,
construction of the campsite and jetty, dredging of a temporary access channel to the jetty,
welding and X-Ray tests for the welded pipes and delivery of the welded pipes to the
trenches connecting new KOT to the Mombasa Port. The EMMP upon which the report is
based focuses on four environmental media which are water quality, biological monitoring,
air quality and noise and vibration measurements. Water quality monitoring includes physical
parameters and chemical parameters; the physical parameters were pH, Dissolved Oxygen
(DO) and turbidity while the chemical ones were Chemical Oxygen Demand (COD), Total
Suspended Solids (TSS) and Perspective Degree. Biological monitoring includes mangroves and
fauna including fish, crustacean and endangered species. The two other environmental media
are air quality and noise measurement at the camp site.
2. Water quality monitoring
Water quality monitoring was undertaken daily from 1st – 30
th April 2021 at two (2) of the
monitoring stations as per the EMMP (MS1-MS2) for the following parameters; pH, dissolved
oxygen and turbidity, total suspended solids (TSS), chemical oxygen demand (COD) and
perspective degree.
Monitoring at MS-3 (campsite) is scheduled to be undertaken in May.
3. Biological monitoring
Biological monitoring was carried out on 17th and 30
th April 2021 at two (2) of the
monitoring stations as per the EMMP and focused on MS-1 and MS-2. MS-1 and MS-2 are
located at the temporary jetty and within the mangrove area respectively.
4. Air quality and noise/vibration measurements
Air quality and noise/vibration measurements are scheduled to be carried out quarterly at the
project site and will be included in the monthly report when reporting times coincide.

5. Results
5.1. Water quality monitoring from 1st – 30
th April 2021
This section presents the results for water quality monitoring for both monitoring stations (MS
1-2) for the monthly report period. These are summarized in Table 1 and 2 below and the
summary of the raw data pooled for both the monitoring stations for the entire month (Table
3). Both the physical water quality parameters i.e. pH, dissolved oxygen and turbidity, and
the chemical water quality parameters i.e. Total Suspended Solids (TSS), Chemical Oxygen
Demand (COD) and Perspective Degree were reported. There was no significant change in
parameters reported except for TSS values reported at both monitoring stations which
decreased by 25.84% and 30.44% at MS1 and MS2 respectively as shown in figures 1 and 2.
This is attributed to decreased sediment load into channel.

5.2. Biological monitoring undertaken on 17th and 30
th April 2021
Biological monitoring was undertaken on two days during the monitoring period. These are 17th
and 30th April 2021 and targeted Monitoring Station 1 at the temporary jetty area and
Monitoring Station 2 within the mangrove area through site visits on land and sea, observations
and interviews with the local fishermen and the Mombasa Kilindini Community Forest
Association (MOKICFA).
5.2.1. Mangroves
There were no changes observed in respect of the status and condition of the mangrove forest
stands at both MS-1 and MS-2.
5.2.2. Interviews with fishermen on biological communities
The EMMP implementing team interviewed local fishermen using a questionnaire to obtain data
and information on impacts of ongoing construction activities on the fishery, their livelihoods
and any possible marine fauna strandings reported in the area since commencement of the
project (Figure 3). Like in the previous interviews, all the fishermen interviewed said that the
project has led to the decline of their daily fish catch. However, this may not be the correct
position since the proponent hasn’t started any dredging works at the site and their response is
probably influenced by anticipated compensation as possibly seasonal variations in availability of
fish and crustaceans. There were no reports of strandings of marine fauna or sighting of
endangered species within the project site or neighboring areas. The filled in questionnaires are
attached to this report.
