Appendix 6.1 Social and Environmental Considerations

1. Environmental Impact Assessment

1-1 General Project Components Affecting Environmental and Social Aspects

The major Project components requested by the Government of Ghana are, improvement of

existing lay-by wharf, construction of access driveway, renovation of administration compound,

construction of additional ice making facilities and pavement of in-port road. The followings

briefly describe the contents of the Project’s components.

(1) Improvement of Existing Lay-By Wharf

There are sunken vessels abandoned near the existing lay-by wharf. These vessels will not

only be nuisance for Project’s construction activities also cause some trouble if they are salvaged

and scrapped without permission from their owner. Those vessels may also cause nuisance during

construction period especially for the mooring spaces for canoes and inshore fishery vessels

which utilize the existing Sekondi Harbour.

(2) Construction of Additional Ice Making Facilities

There are several used boat engines, which are left on the back yard of existing ice making

facilities, will be cleared upon the construction phase. It may cause trouble if they are cleared and

scrapped without permission of their owners.

(3) Pavement of In-Port Road

The Project plans to connect the existing in-port roads to access road. There are several fuel

tanks, which are set on the ground close to the existing in-port road, have no appropriate fences

which prohibit the intruders. This situation poses a safety hazardous issue thus it is essential for

the Government of Ghana to plan the amalgamation of the fuel tanks and setting appropriate

fences for safety reasons.

(4) Construction of Access Driveway

The existence of the sunken vessels, of which may cause some trouble if they are salvaged

and scrapped without permission from owner of vessels, will also pose nuisance for the

construction of an access driveway. Moreover, construction of the access road will cause temporal

relocation of existing several small shops called “kiosk” and “container”.

(5) Renovation of Administration Compound

As the result of renovation of administration compound which will have toilet sewerage, will

cause water contamination.

A-43

Important items, which shall be noted from an environmental and social consideration point

of view, are briefly summarized below.

(1) Temporal and Permanent Relocation of Kiosks and Container

Temporal Relocation of Kiosks and Container

The Project plans to construct the access road from the existing canoe jetty to southward

along the shoreline. The construction of the road will require temporal and permanent relocation

of several small shops called “kiosks” and “containers” thus a meeting was held by GPHA to

discuss the temporal relocation places and procedures with the participants on 13th, July, 2013

while the Study Team conducted survey at the Sekondi Harbour.

GPHA has carried out surveys to figure out the number of kiosks and containers which will

be subject to temporal relocation including the size, selling items and name of owners as well as

A-44

the places for the temporal relocation and the possible assistance such as provision of forklift

GPHA. As the result, GPHA has found that there would be 15 kiosks and containers owned by

13 people for the temporal relocation. GPHA explained the results of the survey to the

participants at the meeting held for the consultation for temporal relocation and could reach

agreement for the procedure of temporal relocation on 1st, August, 2013. GPHA would provide

temporal relocation places which locate in Sekondi Harbour and could accommodate all of them.

It has also been anticipated that 11 of them would be able to return the original places upon the

completion of the construction of access road. The followings briefly describe the small shops

which will be anticipated for permanent relocation upon the completion of the access road.

Permanent Relocation of Kiosks and Container

Among the above 15 small shops, 3containers and one kiosk have been anticipated for

permanent relocation upon the completion of the access road. The four small shops (3containers

and one kiosk) would be able to shift to some of the spaces within Sekondi Harbour which could

accommodate for them. GPHA also plans to provide forklift as well as some staff to drive it.

Indemnity

GPHA is going to indemnify all matters to the people suffering from the new location place,

relocation means, non-business period caused by the relocation in conjunction with “Temporal

and Permanent Relocation of Kiosks and Containers” in this project and so described in attached

Appendix 5.2.2 .

(2) Clearance of Sunken Vessels

Several sunken vessels left on the Sekondi Harbour will be salvaged and scrapped upon the

commencement of construction activities. GPHA has held meetings to explain about the clearance

of those sunken vessels by the following procedures to canoe owners and inshore vessel owners.

GPHA has succeeded to reach agreement with those people to do so.

First, GPHA will contact vessels owners to remove sunken vessels. If they agree to remove

them within a time frame, then they would be no problem.

If vessel owners don’t agree due to some constraints, still GPHA would insist on the removal of

the vessels. If they say they cannot remove and they give up ownership of the vessels, then

GPHA would salvage them, then scrap them or otherwise.

(3) Clearance of Abandoned Vessels

Abandoned vessels left on the ground of both Old Beach area and sandy beach located

northward from the harbour will be cleared by the following procedures which are explained by

GPHA, and agreed by the canoe owners and inshore vessel owners attended at meetings held by

GPHA.

A-45

1) Abandoned Inshore Vessels

The Ghana Inshore Fisheries Association (GIFA) would inform all vessels owners about the

removal of their abandon vessels within a time frame.

If they don’t agree to remove them after the stipulated time then GPHA and GIFA would mark

them and demolish them and give the woods to the fish smokers to be used as fire wood or give

the woods to the prison service.

2) Abandoned Canoes at Old Beach

The chief fisherman would inform all abandon canoe owners for the removal of their canoes

with in a given time.

If they don’t remove them and the time elapses then GPHA and the chief fisherman would

mark the abandon canoes and demolish them and give to the local people for firewood.

(4) Removal of Engines

The following procedures of clearance of used boat engines left on the west side of ice

making facilities were explained by GPHA to the inshore boat owners attended meetings also

held by GPHA.

Ghana Inshore Fisheries Association (GIFA) to inform boat owners to remove all engines.

If they don’t remove them then GPHA and GIFA would remove them from the harbour with in

one (1) month, and sell them as scraps to defray the cost of fuel used by the forklift and the

truck hired.

(5) Removal of Existing Fuel Tanks

Altogether of 15 fuel tanks at Sekondi Harbour will be cleared upon the commencement of

construction activities. GPHA has held meetings with existing fuel dealers to discuss the issue.

GPHA has explained that GPHA planned to install two fuel tanks upon the completion of new

harbour but has not been able to reach agreement with them. GPHA plans to continue dialogue

with them by holding some meetings in order to reach agreement.

(6) Present Situation of Waste Treatment and Sewerage Treatment at Sekondi Harbour

As the results of our interview survey and field survey conducted during this mission, the

following key items have been revealed.

There are mainly three sewerage pipes flushing sewerage directly into seawater of Sekondi

Harbour. Currently, GPHA plans to divert sewerage water to prevent this sewerage water from

flowing directly into Sekondi Harbour based on the results of discussion between GPHA and

STMA.

Toilet sewerage of both Takoradi and Sekondi Harbour will be collected into one cesspit at

each of the harbour. The toilet sewerage is regularly transported and treated at the STMA’s

designated are by GPHA’s trucks. Frequency of the treatment is almost daily basis during high

A-46

fishing season and 3times per week during low fishing season. The cost of the treatment is

20GHC per unit and the expense is paid to STMA. Total frequency of treatment for both of two

harbours is approximately 50-70 units per week.

Used boat engines left on the west side of ice making facilities supposed to be re-used as spare

parts of engines, however, it seemed that they were hardly used.

There are at least of around 100 households living on Old Beach. The Project has no plan to

construct or install some things over there thus it will be NO involuntary resettlement caused

by the implementation of the Project.

GPHA has been entrusted the task of cleaning of harbour, collection of garbage and mowing

grass to some private entities. Total cost of these tasks is approximately 3,000 GHC per month.

Transporting and dumping of the garbage is also entrusted to some private entities. It costs

GPHA approximately altogether 9,000GHC per month for the two harbours.

Water quality monitoring has not been carried out at Sekondi Harbour. However, GPHA did the

water quality sampling once in year 2010, but it was hard to collect the results.

(7) STMA’s Dumping Site

Toilet sewerage and garbage/ wastes are transported and dumped at the STMA’s designated

area by the private entities entrusted by GPHA. The dumping area was constructed by World

Bank’s assistance and was completed in 2010. The dumping area, which is called Sofokrom

(Engineer Landfill Site) with approximately 36ha of surface area and located 7km onward to

Accra from the Project site, has a capacity of accommodating all kinds of wastes including

industrial hazardous wastes except for the medical wastes up until year 2025. Garbage is sorted

by the following three categories at Sofokrom except for the medical wastes.

Solid wastes (general garbage: both organic wastes and nonorganic wastes): Some private

individual come to visit to separate plastics, bins, wooden materials, concrete materials, metals

which are worth to sell as recycled materials.

Liquid wastes mostly toilet sewerage: 6 pools for processing and 2 pools for the final

processing are installed.

Industrial hazardous wastes (oil, contaminated soil with heavy metals): The site is ready to be

sealed for several layers by the special plastic protection sheets for each of the waste. This is

the place for the sledge of Sekondi Harbour generated by construction activities will be treated.

1-3 Outline of Relevant Agency Responsible for Environmental and Social Considerations

(1) Outline of Relevant Agency Responsible for Environmental and Social Considerations

The Ministry of Science and Environment has Environmental Protection Agency (EPA),

which is the Ghana Government’s main body responsible for environmental conservation and its

policy, related laws and regulations, coordination and assessment of policies on environment. EPA

was established based on the Environmental Protection Agency (EPA) Act (Act 490) in 1994.

A-47

Environmental Assessment Regulations LI1652, which plays a basic role for implementing EIA

process, was officially enforced in 1999.

EPA’s organization chart is shown on the figure A6.1(1). EIA contents are assessed by EPA’s

Environmental Assessment and Audit Department coming under Environmental Compliance and

Enforcement Division. EPA headquarter executes the task of registration of project proponents,

review of scoping reports and TOR approval. There are 20 staff allocated at Environmental

Compliance & Enforcement Division, and EPA’s 13 regional offices handle for field survey for

the registered projects for the environmental permit. Overall, there is 360 staff at all of the EPA

offices. Breakdown of the 13 regional offices is 10 regional offices, one regional office in Accra,

one in Tema and another one in Takuwa.

(3) Ghana’s Procedure of Environmental Requirements

Project proponents are required to obtain an environmental permit issued by EPA to

implement projects. Ghana’s Environmental Assessment Regulations are applied upon the

assessment of the required procedures set out by EPA. There are 37 project items required to

obtain the permit listed by the regulations. As for the Project, item No 22 for construction of

roads and infrastructure including sewerage treatment facilities and hydroelectric power stations,

No 31 for land reclamation of water bodies, No 32 for construction of fisheries infrastructure such

as fishing harbours, are related to the procedures of obtaining the permit.

Ghana’s responsible government agency for the execution of environmental policy,

environmental conservation and its laws is EPA which is described on the above section.

Ghana’s Environmental Assessment Regulations list up the projects for each sector being for

subject to the assessment and EPA judges the environmental category based on the regulations.

The procedures of assessment of the project proponent’s application of the permit and issuing the

permit are shown on the figure A6.1(2) below.

A-49

Source：EPA

Figure A6.1(2) Procedures of EPA Environmental Permit

The environmental category judged by EPA has two folds, which are Schdule-1 and

Schdule-2. Schdule-1 is designated for the projects which generate minor or negligible negative

impacts, whereas Schdule-2 for the projects which generate some or serious negative impacts.

EIA is obligated to carry out for the Schdule-2, whereas Schdule-1 is not required EIA.

It normally takes 90 working days which is equal to 18 weeks for the assessment of EIA by

EPA plus some more days to be prepared EIA by project proponents. Length of preparation of

EIA varies depending on the project proponents and the scale of the projects. Upon conducting

EIA which is instructed by EPA to project proponents, a public consultation is required to hold at

either the time of scoping reports preparation period or preparation of EIA reports. When submit

the results of the public consultation report to EPA, the results must show the minutes of meeting

and list up all the participants’ name, address and contact phone number.

Ghana’s Environmental Assessment Regulations, 1999 do not include the clear guideline of

social aspects such as, of involuntary resettlement, impacts to people in poverty, gender issues

A-50

and rights of children. However, along the process of conducting EIA and obtaining the EPA’s

environmental permit, project proponents are obligated to deal with the issues of these social

aspects plus wide range of environmental issues such as pollution controls. For instance, on the

event of relocation of residents and commercial facilities occupying the site illegally, EIA process

requires to project proponents to deal with these issues. The compensation of these people will be

either the payment of cash equivalent value for each case or providing alternative places and

houses for living or commercial facilities to continue business. Discrepancy of the compensation

for relocation between the illegal residents / commercial facilities and legal residents /

commercial facilities is that the payment is calculated based on the assessment of each of the

house and commercial facility and this automatically sets out the discrepancy because the illegal

ones are relatively low value due to the nature of the houses and facilities.

As for the related ports and harbour construction projects, which has been through EPA’s

environmental permit procedures, Study Team could collect some documents of Takoradi Harbour

Reconstruction Project in 2012 implemented by GPHA and the Londhro Port Development

Project included the oil refinery facilities implemented by some private entity.

1-4 Initial Environmental Examination (IEE)

The project has carried out Initial Environmental Examination (IEE) with GPHA staff, and

proposed monitoring items and contents for the aspects on the environmental and social

consideration together with the planning of the environmental check list. The following describes

the results of IEE and the contents of negative impacts on the aspects of environmental and social

consideration.

(1) Environmental Category

The Project will not have serious negative impacts on the aspects of environmental and

social consideration. However, the Project will cause some negative impacts on the aspects thus

the Project is judged to be Category B for JICA’s environmental and social consideration

guideline.

(2) Anticipated Negative Impacts

Implementation process of the Project will cause some negative impacts on both

environment and social aspects at and around the project site. The table shown below is the

1-7 Results of Survey for Environmental and Social Consideration

The results of survey for environmental and social consideration are summarized below.

Table A6.1(6) Results of Survey for Environmental and Social Consideration Likely Impacts Results of Survey

Air Pollution The project will generate dust during construction period. There are approximately 200 small shops and kiosks operating business. It is anticipated to be a little effect for those people except for the several shops locating near the construction site of access roads. Project plans to prepare the temporal yards for the construction which will be located GPHA’s Sekondi Harbour thus it will have very little impact to the local residents. There are some residential areas around the roads between the Project site and the waste treatment area and excavation pit holes thus heavy vehicles will generate dust.

Water Quality Water quality samplings carried out during this mission reveal the existence of coliforms, nitrogen, phosphorus, dissolved oxygen which exceed well over the international standards for the fishing harbour water quality. This could be attributed to the existence of sewerage water generated by the surrounding commercial and residential areas flowing to the Sekondi Harbour as well as the local people’s open defecation including people operating small shops and kiosks. Sewerage water generated from the administration building which will have some annex is anticipated to have some negative impact on the water quality of the Sekondi Harbour but not as serious.

Wastes GPHA has been entrusted the business of treatment of waste within Sekondi Harbour to private entities which collect and transport the waste on daily basis. GPHA plans to continue the entrustment thus the treatment of the waste during the construction period will be handled properly and cause hardly any problems. GPHA also plans to salvage sunken ships and clean the abandoned boats on the land as well as used boat engines left on the land, which will be mostly sold and recycled. This action will generate a little amount of waste. Project will be able to handle the wastes generated by the construction activities by transporting them to the STMA’s designated waste dumping site.

Soil Contamination

It is anticipated that the sledge from the Sekondi Harbour sediment generated by construction activities will cause soil contamination. The sledge will be treated at the STMA’s designated dumping site thus it will not cause any soil contamination.

Noise and Vibration

It is anticipated to cause noise and vibration during construction activities. However, there is no residential area located within 200m from the Project site. Some small shops and kiosks operated their business close to the planned access road area will be affected.

Offensive Odor Organic wastes which cause offensive odour are collected and transported to the designated area by the entrusted private entities on daily basis, and GPHA plans to continue this practice. Fish landed on the Sekondi Harbour are processed only for cutting fins and removing scales by the middlemen (fishmonger) upon the landing at the harbour, and those organic wastes are also collected by the private entities thus those organic wastes will be also caused any problems during construction activities as well as upon the operation of the new harbour.



Temporal relocation of 15 small shops and kiosks during construction for the access road. GPHA has already had series of meetings with those who will be affected to discuss the contents of assistance, temporal places for relocation and procedures GPHA will take. It is anticipated that 11 small shops will be able to be back to the original places and 4 small shops be required to relocate to the new places within Sekondi Harbour. Upon the operation of the new harbour, GPHA plans to amalgamate the fuel tanks to 2 to 4 thus the existing fuel dealers will be affected, and GPHA plans to hold meetings to discuss this issue with those fuel dealers.


The existing Sekondi Harbour is utilized by canoe boats and inshore fishing vessels for landing their catch and mooring their canoes and vessels. These two groups have some conflicts on the issues of the sharing space which will be continued during construction. It is necessary for GPHA to have meetings to discuss the issue and to instruct the space for each group in order to solve this issue. Harbour Advisory Committee, which will handle the management of the new harbour including utilization of the new harbour, will be established upon the operation of the new harbour. It is expected that the forthcoming Harbour Advisory Committee will also handle this issue and thus the conflicts will be mitigated.

Labour Condition

It is anticipated that accidents may occur to the construction workers and people engaging construction activities during construction because of the operation of heavy vehicles and construction activities. The occurrence of accidents will be prevented by implementing safety education and safety practices.

Accidents It is anticipated that accidents may occur not only to the people involved in construction activities but also to the visitors to the harbour and people operating small shops and kiosks because of the operation of heavy vehicles and construction activities. The occurrence of accidents will be prevented by implementing safety education and safety practices as well as installing fences, allocating security personnel, informing construction activities and its duration. Upon the operation of the new harbour, the forthcoming Harbour Advisory Committee will implement the accidents prevention instruction thus the maritime accidents will be reduced.

The following Table A6.1(8) describes the mitigation measures.

Table A6.1(8) Mitigation Measures

Likely Impacts

Rat

ing Impact Severity(e.g. magnitude, area

extent, duration, frequency, reversibility, likelihood of occurrence)

Assumed Mitigation Measures

Air Pollution B

During the reconstruction of the Sekondi Harbour, operation of heavy vehicles and machineries will generate dust and gas emission thus it will cause air pollution.

Construction Phase: Plan appropriate measures, such as, cut the

engines of heavy vehicles and machineries when they are not in use, frequent watering to the site, in order to minimize dust and gas emission from the vehicles and other machineries during construction. Implement them.

Water Contamination

B

Construction activities will cause water contamination to the sea around the project site.

Operation of the new Sekondi Harbour will generate sewerage water which will affect water quality around the project site if it is untreated.

The Project requested GPHA to manage the existing three sewerage pipes at Old Beach area, which are the major source of sewerage effluents to the Sekondi Harbour. GPHA will divert sewerage water to prevent the flow into the Sekondi Harbour. Thus this treatment will reduce the water contamination at Sekondi Harbour.

Planning Phase: Plan appropriate sewerage treatment septic

tanks to comply with Ghana’s effluent standard to treat the sewerage generated by the new administration building.

Construction Phase: Using machineries minimising water turbidity

and installing oil fences. Operation Phase: Check the GPHA’s construction activities on

the improvement (diversion of sewerage) of existing three sewerage pipes set on the Old Beach.

Soil

Contamination B

Construction activities will generate sledge which will cause soil contamination.

Construction Phase: Plan the treatment of the sledge to carry to

STMA’s designated dumping site and accommodate and bury on the sealed places which prevent soil contamination. Implement the plan.

Wastes B

Construction process will generate waste and some of them will be recycled and the rest will be carried to STMA waste dumping site.

Operation of the new Sekondi Harbour, harbour users and visitors may litter some garbage around the site.

Construction Phase: Plan the wastes management plan which will

recycle for most of the construction wastes and be able to carry the rest to the STMA’s designated dumping site. Implement the wastes management plan.

Operation Phase: GPHA hires both local staff such as task force

who clean the harbour and local contractors who collect garbage from the pit and carry to the STMA’s designated area. GPHA shall continue this system to treat garbage.

Also, GPHA will conduct some local awareness campaigns and education on littering by closely working with local people including NGOs.

A-59

Noise and

Vibration B

During the construction of the new Sekondi Harbour, operation of heavy vehicles and machineries will generate noise and vibration in and around the proposed Project site. However, there is no residential area located within 200m from the Project site.

Operation of the new Sekondi Harbour, increase of noise and vibration in and around the site will not occur.

Construction Phase: Use the vehicles and machineries of low noise type. Install noise reduction walls. Implement maximum speed limits within the

site and around the site. Control reconstruction works at night.

Offensive Odour B

During the construction and upon the operation of the new Sekondi Harbour, some organic materials will cause offensive odour if they are left untreated.

Construction and Operation Phase: GPHA hires local staff such as task force who

clean the harbour and local contractors who collect garbage from the pit and carry to the STMA’s designated area. GPHA shall continue this system to treat garbage.

Conduct some local awareness campaign and education to treat garbage appropriately by closely working with local people including NGOs.



B

Some small shops called kiosks and containers at the existing Sekondi Harbour will be negatively affected by the temporal relocation process. The total number of those shops has been estimated as 15 and people own those shops as 13. The Project will require the site clearance including existing small fuel tanks which are operated by about 10 individual private fuel distributers.

Upon the completion of the new harbour, GPHA will amalgamate those tanks into two to four thus those people will be affected.

Planning Phase: GPHA have had a series of meetings with

small shop owners to discuss the temporal places to relocate and assistance measures such as providing forklift together with and operation personnel.

Construction Phase: Hold meetings between GPHA and those

people prior and during the construction to confirm the procedures.

Operation Phase: Hold meetings between GPHA and existing

fuel dealers to discuss the issue of amalgamation and its process in order to reach agreement on this issue.


Local conflicts of interests may be caused between fisher folks operating canoe fishery and inshore fishery for the usage of available landing space and mooring space during construction period.

Also, upon the operation of new Sekondi Harbour, same conflicts may occur.

Construction Phase: GPHA intervene fisher folks operating canoe

fishery and inshore fishery for the usage of available landing space and mooring space during construction period.

Operation Phase: GPHA will establish the Harbour

Management Committee which will encourage and assist the fair utilization of landing and mooring spaces between fisher folks operating canoe fishery and inshore fishery.

Labour Condition BDuring construction activities, some accidents may occur.

Construction Phase: Conduct education to the drivers of the

construction vehicles to drive safely.

Accidents B

During the construction of the new Sekondi Harbour, operation of heavy vehicles and machineries may cause traffic accidents in and around the Project site. Also, accidents may occur to the workers during construction.

Upon the operation of the new harbour, increased frequency of vessels to the new harbour may cause maritime accidents.

Construction Phase: Conduct education to the drivers of the

construction vehicles to drive safely. Operation Phase: GPHA will establish the Harbour

1-10 Procedures of Environmental Permit and its Schedule

(1) GPHA’s Responsible Unit

GPHA has a special unit named ”Port Estate and Environment” which handles the

environmental management and management of ports and harbours land. Both Takoradi Harbour

and GPHA’s headquarter in Tema Harbour have this unit which altogether has 38 staff including 2

administrative staff. Followings describe the major tasks carried out by this unit. In addition to the

following description, the unit also handles the task of obtaining the environmental license from

EPA thus the unit is anticipated to play a major role to obtain the environmental license from EPA

for the Project.

Harbour land (within GPHA’s harbour) lease

Harbour development

Management of harbour facilities

Management of wastes and sewerage treatment generated in harbour

Management of oil leakage in harbour

Environmental awareness

Environmental monitoring of harbour

(2) Schedule of Procedures of EPA’s Permit

The Project site locates at the STMA’s administrative area so that the EPA headquarter and

EPA’s Western Region Office as regional office of EPA will closely working with the procedure of

issuing environmental permit. The EPA headquarter will coordinate the whole process of the

permit and the Western Region Office will assist to hold local stakeholders meetings as well as

conducting local field survey.

EPA has predicted that the Project’s EPA’s environmental category will be “Schedule 2”

mainly because the Project is an expansion of the existing Sekondi Harbour thus the Project will

be required to conduct EIA. On the other hand, GPHA has anticipated that the Project’s EPA’s

environmental category will be “Schedule 1”, for which the EIA is not compulsory, based on their

previous experiences of similar construction projects for ports and harbours and the scale of the

proposed Project.

It is anticipated that the Project’s whole duration of obtaining EPA’s environmental permit is

approximately 8 to 9 months as the table shown below if the Project is judged to be “Schedule 2”

by EPA. However, the whole duration of up to 9months will be shortened.

As for the progress of obtaining an EPA’s environmental permit for the Project, the study team

has confirmed that GPHA would be able to obtain the permit by the end of July, 2014 as the final

deadline. Upon the study team’s visit to Ghana for the explanation of draft report on December, 2013,

the team also confirmed that GPHA had commenced the preparation for the required procedures of

obtaining the EPA’s environmental permit including selection of a local consulting firm to carry out

EIA.

As for the procedure of obtaining the Project’s environmental permit, Mr. Anamo, Director

General of GPHA, made promise to obtain the Project’s environmental permit by the end of July,

2014 when Mr. Anamo discussed the Project contents with the JICA Study Team on 4th, August,

2013 at Sekondi Harbour. An environmental and social consideration staff of the JICA Study

Team explained the matter to the Manager of Port Estate and Environment at Tema GPHA

headquarter, and confirmed their action of sending e-mail to the Study Team to inform the

commencement of the procedures of EPA environmental permit including appointing the local

consultant for the procedures after the team returned back to Accra. The Team has contacted with

GPHA relevant person by e-mail at the end of October, 2013 to confirm the progress of the

obtaining EPA environmental permit, GPHA informed that GPHA appointed the local consultant

to engage the procedures as well as the contents of EIA TOR being set, therefore GPHA would

plan to commence EIA process from November, 2013 and expect to be able to obtain the permit

by the end of March, 2014.

(3) Cost

The Project’s process of obtaining EPA’s environmental permit is described on the above.

The followings describe the cost for the procedure.

Major cost of obtaining EPA’s environmental permit are hiring local consultant to carry the

required tasks and the fee for the assessment by EPA. One of the examples of those costs is the

case of Takoradi Harbour reconstruction project on the year of 2012, which was applied and

obtained the permit by GPHA. This project took almost 9months to be able to obtain the permit

from the time of completion of appointing a local consultant, and cost of GPHA US$205,000 for

hiring the consultant.

According to the local consultant who has conducted EIA and EIS report preparation for the

Takoradi Harbour reconstruction project, for the cost of conducting EIA and EIS report

preparation for the Project, which will be carried by some local consultant, may cost

A-63

US$80,000~95,000.

There are both Assessment Fee and Permission Fee, which shall be paid to EPA for obtaining

EPA’s environmental permit. Ghana’s Environmental Law stipulates that 1% of the total cost of a

project shall be paid to EPA for obtaining the permit by the project proponent. However, this is a

high cost for the project proponent to pay for this kind of fee thus the fee system has been altered

to a system for the Assessment Fee and Permission Fee based on the scale of a project and

severity of its negative impacts, which regulated by amendment of Fees and Charges

(Amendment)Instrument, 2011(L1-1986).

As for the Project, the following fees shall be paid to EPA. In addition to these fees, upon the

issuing the permit, project proponent (GPHA) shall pay the cost for preparation of stakeholder

meetings such as, booking for the places, food and beverage, invitation of the expertise including

daily allowances and accommodation for those persons.

Assessment Fee: 7,790 Cedi

Permission Fee: 2,000 Cedi

1-11 Stakeholder Meeting

A stakeholder meeting for the Project was held at Sekondi Harbour outside of GPHA’s

administration compound on 10th, July, 2013. There were 58 participants attended for the meeting,

who were, GPHA staff at both Sekondi Harbour and Takoradi Harbour, representative of inshore

fishery association, representative of canoe fishery association, representative of middlemen

association, representative of smokers association, representative of Sekondi Harbour commercial

association, representative of Ghana fishermen association, NGOs, local police, department of

immigration, representative of task force of Sekondi Harbour, as well as JICA Study Team

member. The followings describe the major items of the agenda of the meeting.

Explanation of GPHA’s request to Japanese Government

Explanation of time schedule and duration of construction activities

Request of cooperation and understanding of causing inconvenience during the construction

period

Request of cooperation and understanding of clearance of the abandoned boats on both at sea

and on the land as well as used boat engines left over the land

Explanation of time schedule for the group meetings commenced from 11th, July to 13th

July,2013 and request of cooperation for the interview and other forms of survey conducted by

the Study Team

Request of cooperation and understanding of causing inconvenience to the small shops and

kiosks during the construction period

Question and Answer

After the stakeholder meeting, five groups, which are, inshore fishery association, canoe

fishery association, middlemen (fishmonger) association, smokers association and Sekondi

A-64

Harbour commercial association, were invited to attend the stakeholder meeting for each group

commenced from 11th, July to 13th July. Purpose of meetings was to ask their needs and to have

question and answer session. Environmental and social consideration point of view, the key items

and conclusion of the meetings can be summarized as follows.

Members of both inshore fishery association and canoe fishery association attended the

meetings as participants showed understandings of causing inconvenience, and reached

agreement of causing inconveniences of minor relocation of landing space and mooring space

during construction period.

Members of middlemen association, smokers association and Sekondi Harbour commercial

association, who attended the meetings as participants, showed understandings of causing

inconvenience and causing dust and noise during the construction period and reached

agreement of causing these inconveniences.

2. Involuntary Resettlement and Land Acquisition

Involuntary resettlement will not be occurred by the implementation of the Project.

3. Environmental Monitoring and Environmental Check List

(1) Project Proponent’s Monitoring System

GPHA has the unit named “Port Estate and Environment” as mentioned on the above section

which is responsible for the environmental management as well as land management. This unit is

expected to execute the monitoring for water quality and waste treatment. As for the monitoring

activities for social aspects, they will be carried out by both the unit and Sekondi Harbour

Administration of GPHA.

(2) Monitoring Forms

Monitoring items both for construction phase and operation phase are shown on Table

A6.1(11), (12). As for the water quality monitoring for construction phase, country of Ghana has

yet to set standard of water quality at ports and harbours thus the standards shown on the table are

only international one. Moreover, as the results of the water quality survey conducted by this

study mission on July, 2013 revealed that the water quality in Sekondi Harbour exceeded well

over the international standard limits thus the Project shall not have the targeted numerical values

in order to prevent water contamination. For this reason, the water quality monitoring for the

Project aims to monitor the water quality rather than set standard for the limit. Stations set out for

the water quality monitoring shall be the same location set out by the July’s survey.

Appendix 6.2 Natural Conditions

1. Climate Condition

The climate of Ghana is a tropical climate and subject to the influence of north-eastern trade

wind called Hamattan blown from Sahara Desert and south-western monsoon wind.

Seasonally, it is divided roughly into the rainy season and wet season, rainy season as from

April to October, dry season from November to March.

In this study, the weather condition of the Project site is arranged based on the observation

results in the Takoradi Meteorological Observatory nearest to the project sitr.

1-1 Temperature and Precipitation

Figure A6.2(1) shows the yearly changes of monthly average temperature and precipitation

at Takoradi Meteorological Observatory. Average temperature is about 27°C and little fluctuated

from 25°C to 29°C as well as maximum temperature is 30.5°C and minimum temperature is

23.0°C. Range of temperature is rather small as difference of maximum and minimum

temperature in a month is about 3°C as shown in Table A6.2(1).

Yearly precipitation is about 1,200mm. Monthly precipitation is much from April to July in

rainy season and total precipitation of this four months is about half of yearly volume. Number of

days exceeding 10mm in a day is shown in Table A6.2(2). These are about 30 days in a year, and

many in May and June.

1-2 Winds and Atmospheric Pressure

Wind feature around Sekondi is analysed by wind data which is observed at meteorological

observatory of Takoradi airport every hour. Dominant wind direction is SW and rather calm as

wind speed is almost less than 10m/s and frequency less than 5m/s is about 90%.

Moreover, the appearance ratio of the Easterly wind which affects calmness off the fishing

harbour and vessel damage is about 1%. The wind rose at the Takoradi point is shown in Figure

A6.2(2).

Monthly average atmospheric pressure is shown in Table A6.2(3), although there is lack of

data, it is from 1010 hPa to 1011 hPa through a year, there is a tendency it goes up in rainy

season and falls at dry season.

2. Geographical Feature

The topographical survey and bathymetric survey at the project site are carried out in July,

2013, of which results are shown in Figure A6.2(3). Moreover, in order to evaluate a

geographical change of the adjacent area, past geographical feature carried out in April, 1996 is

shown in Figure A6.2(4).

Although the forms of the both contour lines are almost same, depth of the area of -3.0m

contour line at the centre of the breakwater in July, 2013 turn out to the depth of -2.5 m in April,

1994. Moreover, depth at the tip of breakwater is changed from -3.5m in April, 1994 to -3.0m in

July, 2013.

As it is described, about 50cm deep deposition in the area of Sekondi Bay and Sekondi

Fishing Harbour in about 17 years. It means that it was accretion tendency of about 3cm per

every year.

According to the interview survey, these tendencies also appeared in the Takoradi

Commercial Harbour and Sekondi Naval Harbour, and dredging works are carrying out at

north-side of the breakwater.

On the other hand, the situation around the Sekondi Naval Harbour is shown in Figure

A6.2(5), rubble type revetment shore protection is installed on the south of the naval harbour as

shown in Figure A6.2(6). This is considered to be shore protection maintenance for protecting a

hinterland and a road from beach erosion.

stormy wave data are obtained as described in below.

1. The wave database of US Navy calculated by spectrum wave model which is used by

previous project, 2. The design wave used for "The Takoradi Harbour Master Plan (June, 2012)",

3. Stomy wave data hindcasted by spectrum wave model and gloval wind database. Wave heights

are 3.7 m, 3.0 m and 3.3 m, respectively. In this project, offshore wave height of 3.7 m of US

Navy wave database shall be used for design wave height on the danger side.

Wave deformation analysis is carried out to set the incident wave condition at Project Site.

Energy balance equation model are applied for wave deformation by water depth changes at

shallow water area and wave diffraction model are used for wave reduction by the naval harbour

breakwater. In energy balance equation model, a large size calculation area and a small size

calculation area around the Project Site are set up to simulate precisely.

(2) Wave Condition of the Project Site

1) Incident Wave at the Tip of Naval Harbour Breakwater

Wave deformation calculation results are shown in Figure A6.2(8) and (9). According to the

results, the specifications of offshore wave and incident wave conditions are described in Table

A6.2(4) and (5).

Diffraction analysis from the tip of the naval harbour breakwater to harbour entrance is

carried out. Result is shown in Figure A6.2(10). Incident wave direction is set as S47°E changed

10° East direction side in consideration of the danger side. In this analysis, wave reflection by the

naval harbour breakwater is considered, because the breakwater’s alignment is long straight line,

influence of reflected wave may have become large. Incident wave specifications of harbour

Ordinary waves are hindcasted for 5 years period by spectrum wave model and global wind

database, and wave frequency table is integrated. Wave direction of E and wave period of 8 s are

used in this calculation in consider of these wave characteristics.

Result is shown in Figure A6.2(12). Average wave height ratios of each area are described in

Table A6.2(8). In the case of the present condition, wave height ratio by incident wave height is

higher for E direction wave, and is highest at area A of around the preparation berth as 0.74.

Unexceedance frequency ratio in each point is calculated by using ordinary wave frequency

table and above results of harbour calmness analysis. Figure A6.2(13) shows the simulation

process of unexceedance frequency ratio. Rate of operational days of each area for critical wave

height of from 0.3 to 0.6m are calculated as Table A6.2(9).

Unexceedance frequency ratio to the wave height of 0.5 m is 85% in offshore wave, but it is

already 97% or more in the present condition in the harbour.

This frequency situation of wave height, for example about several times exceed 0.5m per

year is similar to the situation of wave conditions estimated by local interview surveys and

fishing vessel damage records.

Rate of operation at area A is about 90% or over for critical wave height of 40cm in

consideration of preparation works or fish landing works.

3-4 Current Conditions

Current observations are carried out at eight points in Sekondi Bay using the

electromagnetic current meter.

Observation is conducted at spring tide (July 21, 2013) and neap tide (July 6-7, 2013)

periods and flood tide and ebb tide, respectively. Current direction and speed are observed at

upper, middle and lower layers in depth.

The current vectors in spring tide situation are shown in Figure A6.2(14). Current directions

and speeds in spring tide and neap tide situation are shown in Table A6.2(10) and (11). Average

current speed is about 20cm/s, current direction goes toward inside of the harbour and has no

connection with flood or ebb tide situations.

3-5 Sediment Transport and Shoreline Change

Situation of sediment transport and shoreline change at Sekondi Bay are analysed by

comparison of bathymetric survey results performed at 1996 and 2013. Figure A6.2(15) shows

the comparison of contour lines of 0.0,-1.0, -2.0 and -3.0m water depth.

According to this, water depth in the north side of the fishing harbour becomes shallower

about 50cm generally. North-side of the naval harbour area including the fishing harbour area is

rather calm area because there is wav sheltered area of the naval harbour from incident wave

direction.

It is generally recognized that sand deposition easily occurred at calm area. Above water

depth changes are concerned with this situation.

Moreover, contour line of -3.0m depth moves toward offshore, and contour line of -1.0m

depth moves toward nearshore. It means mild slope cross section topography called “bar” is

formed at -2m water depth area.

It is surmised that sand bar will be formed at the wave breaking area because bottom

sediments are rolled up there and moved offshore and nearshore area. The formed bar will be

disappeared if a calm wave affects continuously after that. That bar shaped bottom topography is

observed this time suggests that a certain high waves attacked before this time bathymetric

survey.

Since the water depth of wave breaking point is about 2 times of the incident wave height,

waves of 1.0 m wave height is considered to attack by a certain amount of frequency around

Project Site.

4. Seabed Material Survey

Seabed material survey is performed at seven points shown in Figure A6.2(16). Laboratory

tests of moisture contents, specific gravity and sieve analysis are carried out on July 8, 2013.

Moreover, examination of heavy metal contents is carried out at the point of S-1, S-2 and S-3.

Laboratory test results of moisture contents, specific gravity, and sieve analysis are shown in

Table A6.2(12) and a heavy metal content results are shown in Table A6.2(13).

At the point S-3 and S-5 where are outside of the fishing harbour, specific gravity is light

and particle diameter size is small than that of point S-1, S-2 and S-3 where are inside of the

harbour.

Heavy metal contents are mostly less than the standard value of Japan or Australia, however,

disposal in the predetermined dumping site will be needed in excavation at construction work.

5. Soil Investigation

Soil conditions around the breakwater area by previous study are described below. Soil

qualities of surface layer are clay including 30% silt up to the depth of 2m and N value is from 5

to 15. At the layer of deeper than 2m., the soils are weathered sandstone and shows N value of 50

or more.

Soil investigation results performed by this study are described below. Standard penetration

tests are carried out at 4 points (B-1 to B-4). B-1, B-2 and B-3 are sea area and B-2 is land area.

Plate bearing tests are carried out at 2 points (P-1 and P-2).

Figure A6.2(18), (19) show the boring logs of N values and soil characteristics in each point.

Water depth at B-1 and B-3 are almost -3m and surface layer are silty clay up to 1m or 1.3m

below seabed. Water depth of B-2 is about -5m, and surface layer is silty clay up to 0.4m below

seabed and layer of deeper up to 10.5m below seabed is sandstone or shale stone including gravel

and N value is from 20 to 58 getting greater as it became deeper.

Point B-4 is located near the breakwater base, surface is silty sand including gravel up to

4.5m below ground level, N value is from 14 to 50 getting greater as it became deeper. Layer

deeper up to 15m is hard sandstone.

Table A6.2(14) to (16) show the results of unconfined compression test, moisture content

test and specific gravity test. Unconfined compression strength shows 85 to 90MPa (N/mm2) for

sand, and 150 to 155MPa (N/mm2) for sandstone. Moisture contents shows about 10 to 20%.

Moreover, specific gravity shows 2.57 to 2.65.

6. Water Quality Survey

Water quality survey is performed on July 10, 2013 in six points shown in Figure A6.2(21).

Moreover, the water quality survey of tap water at ice making plant and sewage which flows into

Old Beach are also performed. The water quality result in sea area is shown in Table A6.2(17).

Test result of tap water and sewage are shown in Table A6.2(18) and (19).

Tap water qualities are within the Japanese Standard value for tap water, especially, it is

without most crystal exposure of the calcium which will cause a trouble at ice making process.

Around the project site, the content values such as COD, suspended solids, phosphate and

nitrogen are exceeding the standard value of Japan except PH and salinity concentration.

The high value is especially detected from near to the harbour of W-1, W-2 and W-3.

It is considered that main causes are household waste water or human waste which is

discharged directly. Because GPHA is processing periodically and appropriately the waste

generated in the fishing harbour and human waste. Moreover, wastes which are generated on the

simple treatment process at the harbour by fishmonger such as fins, and scales etc. is discharged

appropriately.

There is no big change in the water quality of the project site by comparison with previous

report results.

7. Construction Material Investigation

Construction material analysis is carried out. Two samples of sand, gravels and quarries

from two quarry sites are sampled namely SOFOKROM and JUSTMAC. JUSTMAC VENTURE

LIMITED of quarry-1 is already used as the quarry site for construction work around the site,

because it is only 2.5km distance from the project site and is also large scale for quarry site.

It is confirmed that main kind of this quarry material is granite, and quality and quantity are

considered to be satisfactory for this project.

The results of material investigation are shown in Table A6.2(20).
