1.0 INTRODUCTION
1.1 Project Background
This document presents the Environmental & Social Management Plan (ESMP) for the
proposed Substation reinforcement/rehabilitation projects under the World Bank
sponsored National Electricity and Gas Improvement Project NEGIP.
The NEGIP by environmental screening is a category ‘A’ project according to World
Bank standards requiring a full environmental impact assessment for fresh subprojects
and environmental audit for existing Project sites. The likely over all impacts of NEGIP
considering the diversity of the scope are large scaled, covering a wide area, and
affecting a large population and diverse habitats and ecosystems. This document then
is aimed at improving the viability of investing in the Substation
rehabilitation/reinforcement from an environmental and social management perspective.
By using this tool effectively, the anticipated potential environmental and social impacts
associated with the substation projects will be minimized to the barest minimum thereby
making the projects more sustainable.
NEGIP is an Adaptable Program Loan (APL) aimed at assisting the Federal
Government of Nigeria, through a combination of partial risk guarantees (PRG), for gas
supply to generation stations and International Development Association (IDA)
investments and technical assistance aimed at improving and developing the Nigerian
power sector (substation reinforcement/rehabilitation, transformer repair shop and
distribution facilities improvement etc). It follows a programmatic approach, and will
consist of numerous investments broken into subprojects and guarantees over an
extended time period.
This ESMP provides the bases for managing the environmental and social issues
involved with the implementation of the substation subprojects activities, by
demonstrating how adverse and beneficial environmental as well as socio-economic
and health effects will be managed in all phases of the project implementation. It
therefore describes in specific terms how environmental, health and socio-economic
commitments to be encountered in the Project implementations will be handled.
1.2 Project Location
These rehabilitation projects are being carried out in the PHCN 132/33 kV transmission
Substation in Aba in Abia state. As part of the efforts to improve the Nigerian electricity
transmission infrastructure. Most of the facilities in this station are old and (on paper)
have out lived their life spans. More so, the technology used in manufacturing some of
5
the installed equipments is old and have since been phased out by the manufacturers
thereby making it almost impossible to source their spares.
As all PHCN transmission Substations are similar in lay out, equipment content and are
under the same management (TCN), the content of this ESMP is applicable to all
Substations owned and managed by TCN-PHCN. For the purpose of this write-up, the
Aba 132/33kV Substation at Abia state was visited for direct data gathering.
ESMP Goals and Objectives
The Environmental & Social Management Plan of this aspect of the NEGIP project was
developed in line with World Bank and ISO 14001 Environmental Management System
(EMS) Specifications; other national and international regulatory requirements; and
PHCN Health, Safety and Environmental & Social Management System as documented
in the filed Project ESMF with the Ministry of Environment of the Federal Republic of
Nigeria in 2009.
The ESMF Objectives are to:
Ensure that substation rehabilitation activities are carried out in such a way as to
avoid harms to PHCN employees, contractors and all other stakeholders that
may be affected directly or indirectly by the facility operations.
Ensure that all hazards associated with the S/S rehabilitation and operations
have all been properly identified and assessed. Barriers militating against the
project established and material recovery and emergency measures put in place.
Enforce safe and healthy procedures and practices in all operations and strive
towards an incident free workplace.
Ensure that appropriate trainings are given to staff and adequate equipments are
provided to enable staff work in a healthy and safe manner.
Maintain effective communication with all relevant parties and in particular
communicating ERSU issues to the entire workforce.
Demonstrate visible PHCN management commitment to ERSU issues.
Set clear ERSU targets to staff involved in the project.
Carry out regular review of ERSU performance against targets.
Ensuring that all operations are undertaken with proper regards for the
environment, and strive to reduce environmental risk to a level that is as low as
reasonably practicable.
These objectives shall be achieved by:
Ensuring compliance with all stipulated legislation on protection of the
environment.
6
Integrating social and environmental issues fully into the project development
and operational philosophies.
Promoting social and environmental awareness among workers and
communities around the project sites.
Rationalising and streamlining existing social and environmental activities to
add value, efficiency and effectiveness to the Projects
Ensuring that only environmentally sound procedures are employed during
the different project phases and associated activities
Continuous consultations with relevant regulatory bodies (FMENV, relevant
State environmental protection agencies and other stakeholders), throughout
the projects’ lifecycles.
This ESMP shall remain a dynamic working tool throughout the construction and
operational life span of these Stations. It shall be reviewed with possible changes in
regulatory regimes and in the event of new policies or guidelines from PHCN, WB or the
Nigerian Environmental regulatory bodies. Periodic reviews and updating shall also be
carried out throughout the project lifecycle, to incorporate better management systems
and economic policies.
ESMP Audit Programme
This audit shall be conducted on regular basis to monitor compliance with the project
ESMP. The scope will cover the major project activities including the overall
requirements throughout the life of the project. PHCN performance towards meeting
these requirement will be assessed.
Generally, the audit programme will be conducted bi-annually during construction and at
start up and every five (5) years during operations. The findings from these audits will be
reported to the site ERSU Manager and corrective action plans will be developed and
followed up for performance improvement.
2.0 INSTITUTIONAL ARRANGEMENTS
2.1 Resourcing
Environment, Resettlement and Social Units will be set up in PHCN-TCN and in all the
Substations to be rehabilitated. On site ERSU Manager shall be responsible for all
ERSU-related matters throughout the project period and later during project operations
in order to ensure compliance with environmental regulatory standards. For effective
project implementation, the site ERSU Manager shall work in liaison with the
Contractors’ Engineers & Environmental Officers, and TCN site Engineers to form the
7
Project Management Team (PMT) and the team will report directly to the Project
management Unit of PHCN during the construction period and later to TCN during
operations period.
The Project implementation Organogram defining the line of Communication in the
proposed Substation rehab/reinforcement (NEGIP) Project is presented below.
Responsibilities
Power Holding Company shall retain the primary responsibility of ensuring that
environmental and social commitments are met throughout the project lifespan. The
company shall establish a schedule of responsibility and improvement on matters
relating to social and the environment. Environmental and social issues shall be seen as
a line of responsibilities for which all levels of personnel are accountable.
ESMP Guidelines
The detailed preliminary ESMP guideline developed to cover the entire phases and
activities of the proposed NEGIP Project including responsibilities for implementation
are presented in the Table below.

3.0 DETAILS OF THE SUBSTATION REHABILITATION WORK
These will involve overhauling of the old 1 X 45MVA 132/33kV and 2X30 MVA
Transformers, overhauling of 132kV and 33kV Circuit Breakers, overhauling of 132kV
and 33kV Isolators and earth switches, overhaul of Protection and Control Scheme of
the Station, rehabilitation of the 2KM access road to the substation and extension of 33
KV switch yard Supply and installation of 1X60 MVA 132/33kV transformers with
associated Switch-Gears to replace.
In view of these activities, if proper management of the social, environmental, health and
safety issues are not taken care of, the projects might not be as sustainable as required
according to the World Bank standard. It is based on this that this ESMP becomes very
necessary.
This ESMP is therefore designed to address the environmental and social impacts that
might arise from the rehabilitation activities at the Aba Transmission Substation. It will
also proffer solutions to the lingering environmental issues like house keeping, security,
oil spillage and disposal of scrap materials, e.t.c and also put in place a well trained
Environment, Resettlement and Social Unit (ERSU) that will ensure strict compliance
with World Bank, Nigerian and other International environmental standards in the day to
day running of the PHCN owned Substations.
4.0 Substation Project Risk Assessment and Management
For any Projects of this nature, Risk management is an integral part of the project
execution. The risks related to these projects’ execution and operations were identified
by a structured approach during the project planning stage. Risk assessment visits by
ERSU/Safeguard specialists were conducted in advance of implementation activities to
allow for risk resolution without work interruption during implementation. Results of the
risk assessments and the associated risks reduction measures were evaluated and
documented by the PMU-ERSU and appropriate levels of the TCN site management
staff in the affected substations. This document therefore is a product to be used for
reducing project risks to an acceptable level at a reasonable cost to TCN. Upon project
completion, all other unforeseen risks and their associated resolutions shall be
documented for handover to the site operations personnel who will take over the Project
and continue the operations of the completed facilities.
The responsibility of risk management for these projects during implementation shall lie
with both the Project Management Team (PMT) comprising of the PMU, the rehab
Contractors and the TCN Site management. The environmental and social monitoring
by the PMU-ERSU will reveal if the Contractor project implementation processes are
being successful.
9
The majority of the workers involved in the construction phases of the project will be
Contractors staff, therefore Contractor will pay particular attention to applying
appropriately controlled mitigation measures for their work. Contractors shall ensure that
their HSE system are in line with this ESMP Guidelines. The Contractors working with
Job specifications developed by PMU-ERSU will have direct responsibility for executing
the work using sound engineering fabrication, installation and commercial practices
while maintaining adequate controls. The designs will take into account applicable
Nigerian environmental laws and regulations, and in the absence of such, generally
accepted industry standards shall be used. The Contractors will develop operating
manuals and appropriate documentation regarding the proper operation and
maintenance of the facility for approval by PMU-ERSU. This data will be provided to the
PMU in a timely manner that facility-specific training can be given to the concerned
personnel prior to start-up. Details of what is contained in the Contractors’
environmental manuals will be used by the ERSU in monitoring the job of the
Contractors.
4.1 Project Potential and Associated Impacts
The potential and associated impacts of the NEGIP Sub-station rehabilitation project is
based on observed issues during the risk assessment visits to the Substation and the
FMENV sustainability criteria. The visit to the mentioned Substation revealed the
following:
1. Poor gravelling of the switch yard.
2. Most of the cable trenches are broken and exposed.
3. Water logging of the substation and switch yard.
4. Poor condition of the access road to the station.
5. Dilapidated security fence of substation and switch yard.
6. The whole station is filled up with overgrown weeds.
7. PCB transformer oil leakages
8. There is no space for expansion.
9. The environmental management of this station is not satisfactory and ERSU unit
does not exist.
10. The environmental health and safety of the staffs is poor because the staffs do
not have personal protective equipments to work with.
The nature and duration of the various impacts of the project activities on the ecological
components were identified as follows:
10
4.2 Impact Characterisation
In order to further describe the nature and duration of the various project activities on
the biophysical and socio-economic environment, the identified impacts were further
characterised as direct / indirect, beneficial / adverse, normal / abnormal, short-term /
long-term, reversible / irreversible, cumulative and residual.
Beneficial Impacts: these are impacts that would produce positive effect on
the biophysical or socio-economic environment.
Adverse Impacts: these are impacts that may result in:
Irreversible and undesirable change(s) in the social and/or biophysical
environment;
Decrease in the quality of the biophysical or social environment;
Limitation, restriction or denial of access to or use of any component of the
environment to others, including future generations; and
Sacrifice of long-term environmental viability or integrity for short-term
economic goals.
Direct Impacts: these are impacts resulting directly (direct cause-effect
consequence) from a project activity.
Indirect Impacts: these are impacts that are at least one step removed from
a project activity. They do not follow directly from a project activity.
Normal Impacts: these are impacts that will normally be expected to follow a
particular project activity.
Abnormal Impacts: An impact is considered to be abnormal when it follows
a project activity as against sound predictions based on experience.
Short-term Impacts: these are defined as impacts that will last only within
the period of a specific project activity.
Long-term Impacts: these are impacts whose effects remain even after a
specific project activity.
Reversible Impacts: these are impacts whose effects can be addressed on
application of adequate mitigation measures.
Irreversible Impacts: these are impacts whose effects are such that the
subject (impacted component) cannot be returned to its original state even
after adequate mitigation measures are applied.
Cumulative Impacts: these are impacts resulting from interaction between
ongoing project activities with other activities, taking place simultaneously.
Incremental Impacts: these are impacts that progress with time or as the
project activity proceeds.
11
Residual Impacts: these are impacts that would still remain after mitigation
measures have been applied.

6.0 DETAILED GUIDELINES FOR THE SUBSTATION
REHABILITATION/REINFORCEMENT CONSTRUCTION AND INSTALLATION
This aspect of the ESMP is developed in such a way that it would be inserted in the Bid
documents for the intending Contractors to know what is expected of them during the
project implementation period. Based on their approved submission the PMU-ERSU will
monitor their site activities.
6.1 Project Design & Implementation
The design of the proposed Substation Rehabilitation Project of (NEGIP) is based on
Power Holding Company/TCN Operations, Maintenance and HSE guidelines as well as
relevant technical specifications in agreement with standard power and electrical
industry practices. These philosophies identify relevant standards, codes, practices and
specifications that apply to the technical/operating specifications to be used for the
design, construction and operations of the proposed NEGIP Project. The guidelines also
address controlling deviations from approved standards, codes, practices and
specifications, and providing feedback to improved standards.
6.2 Land Take & Vegetation Clearance
These Projects are to take place within existing TCN Substation and it is expected that
there will be no land take for this substation.
23
All clearing works at the construction site and access roads shall be carried out within a
defined perimeters and only when and where necessary. Clearing of vegetation shall be
kept to the minimum necessary to permit safe operations. Trees felled from site shall be
re-utilized for the benefit of the substation/host communities. Areas cleared in excess of
operational requirements shall be reinstated with indigenous topsoil and vegetation.
6.3 Foundation Works, Land / Sand Filling and Surfacing
Work along access roads and construction site shall be carried out in such a manner
that there is no damage or interference with existing water courses or drainage systems,
utilities, structures, roads or other property of public or private, vehicular or pedestrians
access, other than to the extent that is necessary for them to be removed or diverted to
permit the execution of work within the defined operational perimeter. Any facilities
disturbed or damaged directly or indirectly due to foundation works, site excavations,
land/sand/gravel filling and surfacing activities shall be restored to the original condition.
The clean up and restoration plan shall be in accordance with regulatory requirements.
If existing watercourses and drainage systems are required to be temporarily diverted to
enable the works to be carried out, approval for such diversions shall first be obtained
from the relevant authorities. The diversion shall be maintained while the work is being

9.0 Waste Management Plan
The manner in which wastes are handled, stored and disposed is dictated by the nature
of the waste and this waste management plan takes into consideration the nature of all
wastes that will be generated during the lifetime of the proposed project.
The following objectives form the basis for the waste management plan of the project.
Progressive reduction of wastes with the target to minimize overall
emissions/discharges, which have adverse impact on the environment
To meet the environmental requirements of FMENV and other national and international
waste management as well as PHCN corporate waste management guidelines
To establish, implement and maintain waste segregation aimed at enhancing recycling
To ensure that PHCN and Contractors are responsible for effective waste handling and
disposal process, which shall be monitored by relevant waste disposal authorities
To ensure that waste management programme is in line with the provisions of the
Environmental Management Programme of ISO 14001.
The standard for the plan are binding on all staff and Contractors involved in the
proposed project with respect to the:
Emission or release of pollutant and fugitive gases
Discharge or spill of untreated liquid effluent on land and into surface water
Discharge of solid waste on land and into surface water
Generation of noise.
9.1 Waste Handling Guidelines
For proper handling and disposal, wastes shall be well defined at source and the
definition transmitted along with the wastes to the final disposal points. PHCN and
Contractors personnel shall define and document all wastes generated in the course of
work in a monthly waste stream report, which shall be used to track/monitor wastes
generated from the Substations.
Basic information that must be provided as a minimum for adequate definition of wastes
include:
9.2 Waste type identification
The major categories of wastes envisaged from the Substation Projects are outlined as
follows:
30
Category/Definition
Solid wastes This include felled vegetation/trunks, woods from crates, metals, papers,
printer cartridges and other office services, domestic waste (waste generated from camp
kitchens, packing materials, boxes and plastics)
Liquid wastes This include non hazardous operational waste generated from
work construction sites e.g. lubes, lubricants, sanitary water, paints etc
Gaseous wastes This include combustion products from construction engines,
welding gas, natural gas leaks etc
Hazardous waste is any gaseous, liquid or solid, which due to quantity, physical,
chemical or infectious characteristics have the potential to harm human health,
environment when improperly handled, stored, disposed, transported or treated e.g.
acids, lead, phenols, etc.
9.3 Waste Minimization / Reduction
Waste minimization implies reduction to the greatest extent possible of the volume or
toxicity of waste materials. The four principles of waste minimization process are -
recycle, reduce, reuse and recover, shall be adopted as applicable. The key elements of
the four waste minimization/management principles practices are outlined.
Minimization Definition
Reduce Process modification / design change
Material elimination
Inventory control and management
Material substitution
Improved housekeeping
Reuse Chemical / Oil containers
Reuse waste heat
Recycle / Recover Recycle scrape materials
Recycle paper
Burn waste lubricating oil for energy recovery
Recover oil from tank bottom
31
Waste Segregation
Waste segregation and characterization shall be carried out on wastes that are similar
and may be combined to simplify storage, treatment, recycling and effective
implementation of appropriate waste disposal methods. Wastes shall be segregated,
preferably at source into clearly designated bins at strategic locations. Particular
attention shall be given to the work area where a variety of wastes including fast food
packaging shall be generated. The site HSE Coordinator shall be responsible for
maintenance of the waste segregation scheme at the site.
Waste Disposal
All debris, spoil materials, and other wastes shall be cleared regularly from the site and
dispose off at approved dump sites operated by designated waste disposal authorities.
Instructions on material safety handling sheet shall be strictly adhered to and shall form
basis for the disposal of wastes related to such products. Wastes in transits shall be
accompanied and tracked by waste disposal notes. The note shall as minimum contain
such information as date of dispatch, description of wastes, waste quantity, container
type, designated disposal site and method, consignee name, means of transport and
confirmation of actual disposal time and date
Waste management audit of facilities shall be carried out in consultation with the HSE
Department of PHCN, and findings shall be properly documented and followed up.
Accommodation, catering services areas and work site shall maintain acceptable
standard of hygiene and good house keeping.
10.0 GENERAL Security Plan
The project team led by the ERSU Manager shall ensure that adequate security
arrangements are made to handle security related incidents effectively. The project
team will identify, evaluate and manage risks to personnel and property arising from
theft, malicious practices, crime, civil disorder or armed conflict.
In addition, each Contractor will be required to prepare a project security plan and
submit to PHCN for review and approval before mobilization to site. The project will also
organize a security workshop to identify, evaluate and recommend contingency plans for
all security risks.
32
10.1 Journey Management Plan
PHCN and Contractor shall follow its journey management procedures strictly. Trips
shall be planned and combined to reduce driving exposures, mandatory use of seat
belts by drivers and passengers in company and Contractors vehicles shall be enforced.
All drivers shall attend defensive driving course while night driving (out of town limits)
shall be discouraged.
Each trip/journey to be undertaken during the proposed project shall be managed in
such a manner that will not result to harm to life or property. A journey management
plan specific to each trip shall be produced and submitted to the Site HSE Coordinator
for approval. The details of the journey management plan shall include proposed
mobilization date, mode of transportation, routes, type of cargo as well as the details of
the JHA conducted for the trip. The Site HSE Coordinator may only approve the trip if he
can confirm that all necessary precautions have been taken to forestall transport
accidents/incidents.
10.2 Accident/Incident Management Plan
Accidents do not just happen but are caused mainly due to human factors. They result
in pains to the victims and their families, and waste of money and resources and time to
the Company. Consequently, the main priority to PHCN shall be to prevent accidents
during mobilization, construction and operations stages of the proposed projects.
Prevention of workplace accidents during the proposed projects shall be achieved using
the JHA tool and approved work plan/instructions by supervisors.
Consequently, the technical team must conduct JHA for all HSE critical activities and
develop written and explicit work plans/instructions for such operations. The work
instructions shall integrate the recommendations of the JHA. It is only upon submission
of the written work instructions and the supporting JHA document that the Site HSE
Coordinator may consider the project activity for approval. Project activities may only be
approved if the site HSE Coordinator is objectively convinced that the Written Work
Instruction (WWI) are practicable, safe and in accordance with regulatory requirements.
The use of JHA and WWI as work management systems shall include job planning and
permitting, shift / tour handover meetings and logs, special procedures governing higher
risk activities, control of simultaneous activities, energy isolation and workplace
preparation, management controls for temporarily removing safety devices, and
reinstating the facilities and preparing to restart operations. It shall also include
33
requirements for reviewing completed jobs and capturing and communicating lessons
learned about the work and management system.
Accidents shall be reported and investigated to the ERSU Manager in line with PHCN
accident reporting procedure. All personnel shall be encouraged to report all
accidents/incidents and to cooperate in the investigation of such occurrence. Staff shall
be made to know that accidents/incidents investigation are “fact finding” and not “fault
finding” exercises and are particularly useful as lessons in preventing re-occurrence.
10.3 Emergency Response Plan
The PMT and Contractors will demonstrate that all potentially significant hazards and
potential impacts of the project activities have been identified, the associated
risks evaluated and understood, and that control and recovery measures to effectively
manage these risks and impacts are in place before mobilization to site. PHCN will
assist Contractors, where necessary, with the provision of a generic hazard list for
guidance.
In case of an emergency, Contractor emergency response procedure will be activated.
Its objectives are:
To ensure no loss of life
To ensure that the environment is protected
To ensure that manpower, equipment and funds are available to effectively contain the
emergency (fire, explosion, electrocution, shocks, accident, spill clean up for
oil/chemical, etc)
In order to ensure that good record keeping is maintained and accurate information
concerning emergency are disseminated to the workers, public and government,
the under mentioned procedures cover the information and issues on the following:
Transformer shut down
Search for leakages
Isolation of supply points
Notification of authorities
Safety precaution and environmental proceedings
Repair methods and procedures
Emergency repairs
Contractor arrangement
Re-commissioning and start up
34
The PMT and Contractors will identify all potential emergency situations and develop
procedures to use in such scenarios as explosions or fires, hydrocarbon/chemical spills,
weather related disasters, hostage taking, community disturbance, kidnapping, etc.
Emergency drills will be conducted to demonstrate preparedness for response and
schedule of drills and testing of emergency instruments will be prepared by
PHCN/Contractors on the proposed projects.
Every technical Contractor on the proposed projects will prepare and submit for
approval contingency plan for emergency situations and possible incidents beyond the
capability of site facilities.
10.4 Consultation Plan
This involves soliciting people’s views on proposed actions and engaging them in
dialogue. It is characterized by two way information flow, from project authorities to
people, and from people to project authorities. The overall aim of the consultation plan
for the project therefore is addressing the concerns and opinions of the stakeholders
with the ultimate view to assuring a smooth project implementation.
Consultation about these rehab/reinforcement projects have been initiated by the PMU-
ERSU to Federal Ministry of Environment, the World Bank Safeguard Team, PHCN-
TCN HQ & project sites, surrounding Communities and shall remain a continuous
process during implementation. The programme for the project construction and
operations stages include:
Visits and courtesy calls on community leaders and other stakeholders to discuss the
effectiveness of the addressed social issues on the lives of the host communities.
Direct visit to the affected populations to consider (through questionnaires, interviews
and visual observations.
Organizing large public meetings (participatory rural appraisal- PRA) to discuss public
welfare, clarify misconceptions and address new issues as regards the project.
Holding workshops and extension courses on resource management (using simply
written materials, visual representation, videos and scale models to decode technical
languages) and sensitising local people on the latest impact mitigation techniques.
Organizing public seminars aimed at identifying new ways of rendering socio-economic
assistance for the locals.
Establishing a voluntary participatory programme in the local media, television and
radio) through which NGOs, CBOs and other key stakeholders concerned and the
35
general public can comment on various aspects of the project and to ensure that all
socio-economic and environmental issues are adequately addressed.
In case of any Grievances, the affected person(s) should come to or write the CEO of
PHCN-TCN and copy the head of Substation who then will attempt to resolve any
grievance. He will liaise with the PMT in sorting out the grievance and notify the CEO
PHCN. When the CEO of PHCN-TCN cannot resolve the grievance himself, the
offended can then seek redress from any Court of Law in Nigeria.
10.5 Communication Plan
Effective two-way communication between PHCN and Contractor staff on HSE and
security issues will include awareness programmes to motivate staff and Contractors.
HSE and security information experiences will be shared between PHCN and
Contractors to facilitate improvement in HSE and security performance.
Contractor shall ensure its staff involved at all levels in the proposed projects become
familiar with the importance of compliance with the adopted HSE policy, regulatory
compliance plan, security plan and their individual roles and responsibilities in achieving
their compliance.
Each person shall be aware of his respective work activities, inherent job risks and
hazard and their controls, mitigation measures and emergency and response
procedures that have been established. They also need to be aware of potential
consequences of departure from agreed operating procedures. Consequently each
Contractors will have a project communications focal point to enhance communications
with the Contractor project team at various locations. Contractors will set up appropriate
procedures and lines of communication to handle HSE and security issues (e.g. direct
access to the nearest clinic, direct access to emergency services, etc).
Contractors should be able to communicate easily with their base offices, work site and
local PHCN in an emergency situation. Appropriate safety programmes and promotions
need to be employed in order to effectively promote HSE and create awareness e.g.
minutes of meetings, plans and performance targets, HSE performance on news board,
posters, bulletins, video, news flash, e-mail etc.
36
Appropriate HSE incentive programmes should be established to promote individual
HSE performance improvements e.g. suggestion boxes, personal recognition,
observation of annual safety week, HSE performance bonus schemes etc.
11.0 Commissioning/Hand over Plan
The risks associated with the commissioning and handover phase of the Projects will be
adequately evaluated and will be covered by detailed commissioning procedures and
guidelines. The Engineering, Procurement, Installation and Commissioning (EPIC)
contract strategy will allow time for familiarity of the commissioning/operation team. This
will allow for effective supervision and carryover of priority items into the operation
phase. A pre-commissioning audit will be carried by the PMT for the proposed projects.
Specific commissioning plans covering all significant Contractor commissioning
activities, particularly control of potential dangerous operations during the
commissioning will be developed. The proposed facility will not be put into operation
unless commissioning approval is received from PMU and PHCN-TCN.
12.0 Decommissioning / Abandonment Plan
The design and facilities shall take due recognition of the need to decommission the
Transmission Substation and the ancillary facilities at the end of their operational life,
the abandonment plan shall take due note of the current national and international
legislative requirements.
The following shall be consider at the end of the project lifecycle:
Need for facilities decommissioning and notification to FMENV.
Team shall be set up to study and plan the decommissioning/abandonment programme
in a manner that meets standard requirement.
An Environmental Evaluation Report (EER) to determine if the activities carried out at
the site have caused any detrimental effects and if any, discuss mitigations and
restoration measures.
In-depth Environmental Studies for the actual removal of equipment (demolition) has to
be carried out.
37
ANNEX 1
ENVIRONMENTAL INTERNAL AUDIT OF ABA 132/33 KV SUBSTATION ABA, ABIA
STATE
The Aba 132/33 KV substation is located in Aba town in Abia state with fifteen to twenty
minutes drive from the town. The access road to the substation is in a very poor state
and it is about 2-4 km. The station was commissioned in 1962 with all the equipments in
it and other associated substation facilities. This substation services Aba township,
Umuahia, Echie and every parts of Abia state except Arochukwu with power supply.
The substation has its surroundings over grown with weeds and the switch yard water
logged whenever it rains. The security of this station is poor has the fence is dilapidated.
Only very office spaces exist. Due to the age of the transformer, the oil contains PCB
and leakages exist. This is a serious environmental hazard. The access road to the
station is in a deplorable condition, the switch yard condition is very poor and not
illuminated. The cable trenches covers are broken and collapsed.
The environmental management of this station is not satisfactory and ERSU do not exist
in the substation. The environmental health safety of the staffs is poor as the staffs do
not have personal protective equipments to work with.
This ESPM is designed to address the environmental and social impacts that may arise
from the rehabilitation activities at the Aba transmission substation and as well establish
an ERSU within the substation that will supervise subsequent environmental audits of
the substation and implement the reports of same at the close of the rehabilitation
project.
