Chapter 1 : ENVIRONMENT MANAGEMENT PLAN
The Environmental and Social Management Action Plan (ESMP) is required to ensure sustainable
development of the road during construction and operational phases. ESMP is site and time
specific. For the proposed construction packages of the project road, ESMP has been designed for
each cluster. The ESMP has two main component (i) Generic ESMP and (ii) Specific ESMP. The
generic ESMP is applicable for all the road clusters, but the specific ESMPs are applicable only to
the specific clusters. The generic and Specific ESMPs are being developed considering the
operation policies of World Bank as well as the National Policies on Environment.
The implementation of ESMP is important. For this an institutional framework has been developed
and roles and responsibilities of the various line departments are made. Some capacity
development program are also identified as part of the ESMP as sub-project. The essence of the
project is its proper maintenance during and post rainy season. This is also to be considered and
need of community based implementation program suggested.
In general, SPIU of Osun state, Nigeria (with assistance from Contractor and Independent
Engineer/Supervision Consultant) is the responsible entity for ensuring that the mitigation measures
are carried out. Mitigation measures for generic impacts are listed in Table 1.1. The list provides
reference implementing organisation and responsible entity.
1.1 SPECIFIC ACTIVITIES BY SPIU
The role of SPIU in the implementation of ESMP involves the following activities:
ESIA clearance from Federal Ministry of Environment, if required;
Clearance of ESIA from World Bank;
Disclosure of ESIA document in Nigeria as well as in the info shop of World Bank and
Permission from Forest Department for felling of trees, wherever applicable.
1.2 SPECIFIC ACTIVITIES BY CONTRACTOR
The activities to be performed by the contractor to implement the ESMP shall comprise the
following:
Confirm the Tree Cutting Schedule based on the final design and provide modified schedule to SPIU.
Fell the trees after SPIU secures Forest Department permission, wherever applicable;
Fell the trees in farm land after SPIU provides necessary compensation to the farm land owners;
Finalizing the selection of material sources (quarry and borrow material, water, sand etc.) ;( refer Annexure 1.1, 1.2, 1.3 and 1.4).
Selection, design and layout of construction areas, labour camps etc. (Refer Annexure 1.6)
1.3 SITE SPECIFIC MANAGEMENT PLAN-CLUSTER-A (IWO Region)
1.3.1 Cultural Properties
In this project there is no impact on cultural property (e.g. church, mosque etc.). Impact on cultural
| Page (2)
SECL, Nigeria in JV with VSPL, India
in JV with
properties during the road construction phase in the Corridor of Impact will be avoided through
adequate scheduling of vehicles and construction machineries. Care shall be taken for the chance
found cultural properties. It is the prime responsibility of the contractor to inform the SPIU’s
Environment and Social safeguard specialist regarding the chance found cultural property so that
necessary safeguard measure can be taken up.
1.3.2 Sensitive Features
Along the various roads identified for development in IWO region, it has been observed that in
Road 2, there exists Ogboagbaa hospital (from chainage 3+125 to 3+175). At this place a noise
barrier may be required to minimize the future increase in traffic noise level from induced traffic.
Noise barriers in the form of compound walls have been proposed to a height of 2m.
1.3.3 Community properties
As such in this section no such community property is going to get affected due to the proposed
construction of project road. There is no impact on ground water resources, bus-shelter/bus stop,
school, water tank, palm oil production unit.
1.3.4 Farm Lands, Bushes and Tree cutting:
As such in this section no such farm land is adjacent to project has been identified. The farm land is
at least 2-3m apart from the road sections and there are naturally grown bushes along the project
roads. Private farm land owners shall be compensated if their land is going to be taken for this
project for the loss of livelihood, if any.
1.4 IMPLEMENTATION OF ESMP
The Environmental Officer of the contractor should be available for the entire duration of the project
and shall be primarily responsible for compliance of ESMP. The Environmental Specialist from the
Independent Engineer/ Supervision Consultant shall monitor the compliance of the ESMP and all
the design drawings of various civil structures shall be implemented after his approval. The
proposed organogram for the implementation and monitoring of ESMP is presented in figure 1.1.
The details of the implementation and monitoring schedule of ESMP are described in Chaper-2.
The key issues that require special attention along with the mitigations to be implemented have
been detailed in Table 1.1.

1.5 ENVIRONMENTAL MONITORING PROGRAMME
The Environmental Monitoring Programme has been detailed out in chapter 3. Successful
implementation of the Environmental Monitoring Program is contingent on the following:
The Independent Engineer is to request the Contractor to commence all the initial tests for monitoring (i.e. for Air, Water Quality and Noise Levels) early in the Contract to establish 'base' readings (i.e. to assess the existing conditions prior to effects from the Construction activities being felt).
The Independent Engineer is to request the Concessionaire / Contractor to submit for approval a proposed schedule of subsequent periodic tests to be carried out.
Monitoring by the Independent Engineer’s Officer of all the environmental monitoring tests, and subsequent analysis of results.
Where indicated by testing results, and any other relevant on-site conditions, IE to instruct the Concessionaire / Contractor to:
o Modify the testing schedule (dates, frequency)
o Modify (add to or delete) testing locations
o Verify testing results with additional testing as/if required
o Require recalibration of equipment, etc., as necessary
o Request the Concessionaire to stop, modify or defer specific construction equipment,
processes, etc., as necessary, that are deemed to have contributed significantly to
monitoring readings in excess of permissible environmental "safe" levels.
1.5.1 Monitoring of Earthworks Activities
Most of the environmental problems related to the construction works are anticipated to be
associated with the earthworks, particularly for the Quarries and Borrow Areas. Details
regarding the guidelines and procedures adopted to minimise the environmental impacts of
opening, operating and closing of Quarries and Borrow Areas are presented in Annexure 1.1
to 1.4. Other environmental effects associated with the earthworks including the development
of adequate temporary drainage to minimise detrimental effects (e.g. erosion) due to run-off,
and safety aspects related to Works implementation.
1.5.2 Monitoring of Concessionaire / Contractor's Facilities, Plant and Equipment
All issues related to negative environmental impacts of the Contractor's Facilities, Plant
and equipment are to be controlled through:
The Contractor's self-imposed quality assurance plan
Regular / periodic inspection of the Concessionaire / Contractor’s plant and equipment
Monthly appraisal of the Contractor.
Other environmental impacts are to be regularly identified and noted on the monthly appraisal
inspection made to review all aspects of the Contractor's operation. The officer is to review all
monthly appraisal reports, and through the team leader is to instruct the Contractor to rectify
all significant negative environmental impacts.

the reporting time of the contractor shall be decided upon by the concessionaire. The SPIU
Site Office will be responsible for setting the targets for the various activities anticipated
during construction phase in consultation with the IE/SC and obtaining agreement from the
Contractor after mobilisation but before beginning of works on site. The contractor will report
from then on regarding the status on each of these. The SPIU Site Office will monitor the
activities through its own staff or the consultant’s Environmental Specialist after it has
obtained the Contractor’s report with the Consultant’s remarks on it during the construction
phase. During the operation phase, the supervision as well as reporting responsibilities will lie
with the SPIU Site Office.

Chapter 3 ENVIRONMENTAL MONITORING PROGRAM
Environmental monitoring is an effective tool in making necessary recommendations and adopt
suitable control strategies so that menace of rising environmental pollution could be minimized and
a relief be extended to the people including labours in case of any damage caused under
occupational health hazards. The monitoring is necessary for the following reasons:
To assess what impacts have occurred;
To evaluate the performance of mitigation measures proposed in the ESMP.
To ensure that the conditions of necessary consent and approvals are adhered to.
To suggest improvements in management plan, if required
To see that benefits expected from the EA are achieved as the project proceeds.
To meet legal and community obligations.
3.1 PERFORMANCE INDICATORS (PI) OF MONITORING
The physical, biological and social components, which are significant in affecting the environment
at critical locations, have been suggested as Performance Indicators. The following specific
environmental parameters can be qualitatively measured and compared over a period of time and
therefore selected as Performance Indicators for monitoring due to their regulatory importance and
the availability of standardized procedures and relevant expertise.
Ambient Air Quality
Noise Levels
Water Quality
Soil Quality
Plantation and Survival Rate
3.2 MONITORING OF PERFORMANCE INDICATORS
3.2.1 Ambient Air Quality (AAQ) Monitoring
The baseline air quality in these project sections do not show any significant pollution as the areas
is still in a virgin condition. However, with the construction of roads there is estimation of
movement of heavy vehicles during the construction phase as well chance of increase in induced
traffic during the operation phase.
The major increase of pollution in the region during the construction phase would be dust as the
existing roads are earthen in nature. Hence constant monitoring of PM10 and PM2.5 may be
required. These parameters are to be monitored at selected locations such as plant and machinery
sites, concrete mixer site excavation works, etc. starting from the commencement of construction
activity. The chance of increase in other pollutants like SO2, NOx and CO but are estimated to be
negligible and will be intermittent in nature during the construction stage.
However, during the operation stage monitoring is required to be done for all the parameters like
Particulate Matter (Size less than 10micron or PM10), Particulate Matter (Size less than 2.5 or
PM2.5), Sulphur Dioxide (SO2), Oxides of Nitrogen (NOx) and Carbon Monoxide (CO). These
parameters need to be monitored at the first 5 years of the operation stage to establish a data
bank to ensure that the project has not made any significant impact to the nearby settlements and
vegetation. The monitored results are to be checked with the standards of FMEnv/State Ministry of
Environment.
3.2.2 Ambient Noise Monitoring

SECL, Nigeria in JV with VSPL, India in JV with
The measurement for monitoring the noise levels to be carried out at sensitive locations and at
construction sites along the project road in accordance to the Ambient Noise Standards of FMEnv.
Sound pressure level would be monitored on twenty-four hour basis.
3.2.3 Water Quality
Water quality of local water resources that is used by local community shall be monitored.
The water quality during the construction phase shall be monitored at the major culvert
construction site at the downstream mainly for pH, total solids, total suspended solids, total
dissolved solids. In addition, the parameters like BOD, COD, Phosphate, Nitrate as well as E.Coli
be monitored during the construction stage.
During the operation stage in order to capture information on impact on surface and ground water
quality at least a trend shall be set for the first 3 years of the operation stage for 2 seasons in the
year for the parameters as suggested in American Public Health Association (APHA)/State
Ministry of Environment (Osun).
3.2.4 Soil Quality
The soil quality of the surround fields close to the construction site and plant site will be monitored
to understand the impact of soil quality. The physic-chemical parameters recommended for
analysis are physical Parameter: Texture, Grain Size, Gravel, Sand, Silt, Clay; Chemical
Parameter: pH, Conductivity, Calcium, Magnesium, Sodium, Nitrogen, Absorption Ratio.
3.2.5 Plantation and Survival Rate
The widening and up gradation of the project requires felling of roadside trees. This loss will be
compensated by compensatory afforestation. The compensatory avenue plantation shall be made
as per the guidelines of forest department. Two times of the tree cutting will be compensatory
afforested (cost of the plantation budgeted in ESMP).
3.3 ENVIRONMENTAL MONITORING COST
A separate budgetary provision has been made for implementation of Environmental Monitoring
Plan. The environmental monitoring cost is estimated based upon the environmental monitoring
program being considered in Table 3.1. A budgetary provision of Naira 4.755 million has been kept
for environmental monitoring during construction stages. For operation stage Naira 3.91 Million
has been considered for first 5 years of operation stage.

Annexure 1.2: Guideline for Rehabilitation of Quarries and Borrow Areas
Quarries and Borrow Areas
The contractor shall use materials from the existing and licensed quarry areas only. In case any new
quarries are opened by the contractor, he shall secure permissions for the same and shall follow the
rehabilitation plan.
The objective of the rehabilitation programme is to return the borrow pit sites to a safe and
secure area, which the general public should be able to safely enter and enjoy. Securing borrow
pits /quarry sites in a stable condition should be a fundamental requirement of the rehabilitation
process. This could be achieved by filling the quarry / borrow pit floor to approximately the
access road level.
It is important to plan restoration from the outset and coordinate restoration with quarrying
activities. In addition to the bio-diversity issues, land planning considerations are also taken into
account when defining a rehabilitation project in order both to preserve the environment and to
generate income for the local communities. In this framework quarry rehabilitation often leads to
the creation of wetlands and natural reserves or recreation areas.
Special quarry / borrow pit rehabilitation plan should be specified according to the location and
shaping of the mining slopes after exploitation and overburdened dump, with different
subsequent uses e.g. forest, meadow, water body etc., the re-greening and replanting methods..
Other criteria which should be followed for rehabilitation of quarry/ borrow pits are as given
below:
Quarries and borrow pits will be backfilled with rejected construction wastes and will be given a
vegetative cover. If this is not possible, then slopes will be smoothed and depression will be filled
in such a way that it looks more or less like the original ground surface.
During works execution, the contractor shall ensure preservation of trees during piling of
materials; spreading of stripping material to facilitate water percolation and allow natural
vegetation growth; reestablishment of previous natural drainage flows; improvement of site
appearance; digging of ditches to collect runoff; and maintenance of roadways where a pit or
quarry is declared useable water source for livestock or people nearby. Once the works are
completed, and at own expense the contractor and contractor shall restore the environment
around the work site to its original splits.
To create a safe environment, the faces of borrow pit excavation sites have to be reduced to a
naturally stable slope or be adequately fenced to prevent access to the top and bottom of the
faces. Such a fence must be of a height as prescribed under local mine act with a barbed wire
top strand designed to exclude the public from the quarry area. Depending on the location of the
site presence of a permanent lake is considered to be a satisfactory alternative to a fence.
Appropriate plant species for the planting programme have to be selected in consultation with
ecological consultant and local forest department and farm land owners for the loss of economic
trees made during the quarry and borrow operations.

sources are not available. The Contractor shall prepare a Redevelopment Plan for the quarry site and
get it approved by the IE.
The construction schedule and operations plans to be submitted to the IC prior to commencement of
work shall contain a detailed work plan for procuring materials that includes procurement,
transportation and storage of quarry materials.
CONSTRUCTION STAGE
Development of site: To minimise the adverse impact during excavation of material following
measures are need to be undertaken:
i) Adequate drainage system shall be provided to prevent the flooding of the excavated area
ii) At the stockpiling locations, the Contractor shall construct sediment barriers to prevent the
erosion of excavated material due to runoff
iii) Construction of offices, laboratory, workshop and rest places shall be done in the up-wind of
the plant to minimize the adverse impact due to dust and noise.
i) The access road to the plant shall be constructed taking into consideration location of units
and also slope of the ground to regulate the vehicle movement within the plant.
iv) In case of storage of blasting material, all precautions shall be taken as per The Explosive
Rules, 1983.

Vegetative Cover:
Vegetative cover must be established on all affected land.
Topsoil must be placed, seeded, and mulched within 30 days of final grading if it is within a
current growing season or within 30 days of the start of the next growing season.
Vegetative material used in reclamation must consist of grasses, legumes, herbaceous, or
woody plants or a mixture thereof.
Plant material must be planted during the first growing season following the reclamation phase.
Selection and use of vegetative cover must take into account soil and site characteristics such as
drainage, pH, nutrient availability, and climate to ensure permanent growth.
The vegetative cover is acceptable if within one growing season of seeding:
The planting of trees and shrubs results in a permanent stand, or regeneration and succession
rate, sufficient to assure a 75% survival rate;
The planting results in 90% ground coverage.
The site shall be inspected when the planting is completed and again at one year to ensure
compliance with the reclamation plan.
Certificate of Completion of Reclamation
Contractors have to obtained certificate of satisfaction from the landowner and submit it to the
Engineer before final payment is to done.

Annexure 1.5: Guidelines for Sediment Control
Prior to the start of the relevant construction, the Contractor shall submit to the Engineer for approval,
his schedules for carrying out temporary and permanent erosion / sedimentation control works as are
applicable for the items of clearing and grubbing, roadway and drainage excavation, embankment /
sub-grade construction, culverts and other structures across water courses, pavement courses and
shoulders. He shall also submit for approval his proposed method of erosion / sedimentation control
on service road and borrow pits and his plan for disposal of waste materials. Work shall not be started
until the erosion / sedimentation control schedules and methods of operations for the applicable '
construction have been approved by the Engineer.
The surface area of erodible earth material exposed by clearing and grubbing, excavation, borrow and
fill operations shall be limited to the extent practicable. The Contractor may be directed to provide
immediate control measures to prevent soil erosion and sedimentation that will adversely affect
construction operations, damage adjacent properties, or cause contamination of nearby streams or
other watercourses. Such work may involve the construction of temporary berms, dikes, sediment
basins, slope drains and use of temporary mulches, fabrics, mats, seeding, or other control devices or
methods as necessary to control erosion and sedimentation.
The Contractor shall be required to incorporate all permanent erosion and sedimentation control
features into the project at the earliest practicable time as outlined in his accepted schedule to
minimize the need for temporary erosion and sedimentation control measures.
Temporary erosion, sedimentation and pollution control measures will be used to control the
phenomenon of erosion, sedimentation and pollution that may develop during normal construction
practices, but may neither be foreseen daring design stage nor associated with permanent control
features on the Project.

Silt fencing may be provided to prevent sediments from the construction site entering into the nearby
watercourses. The silt fencing consists of geo textile with extremely small size supported by a wire
mesh mounted on a panel made up of angle / wooden frame and post. It is expected a single person
will be able to drive the angles by pressing from the top. The frame will be installed at the edge of the
water body along which construction is in progress. Silt fencing is proposed for a length of 150m. This
is based on the primary survey data inventory of cross drainage structures to be developed/replaced
in the project. Depending on the length of the individual water body, the number of units of silt fencing
to be installed is decided by the Independent Engineer. A typical drawing of silt fencing is given
below:
