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.
