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 SPIUThe 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 CONTRACTORThe 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) in JV with | Page (6) 1.3 SITE SPECIFIC MANAGEMENT PLAN-CLUSTER-A (IWO Region)1.3.1 Cultural PropertiesIn this project there is no impact on cultural property (e.g. church, mosque etc.). Impact on cultural 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 FeaturesAlong 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 propertiesAs 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 ESMPThe 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.

In case of emergency the Plant Engineer shall immediately notify the Environmental officer for necessary actions.2.3 REPORTING SYSTEMReporting system provides necessary feedback for project management to ensure quality of the works and that the program is on schedule. The rationale for a reporting system is based on accountability to ensure that the measures proposed as part of the Environmental Management Plan get implemented in the project. Reporting system for the suggested monitoring program operates at two levels as: Reporting for environmental condition indicators and environmental management indicators  Reporting for operational performance indicators at the SPIU site level. in JV with | Page (42) Detailed engineering design, safeguards studies and Preparation of bidding documents for prioritized 222.83km rural roads in osun state of Nigeria ESMP (IWO Region)The reporting system will operate linearly – contractor who is at the lowest rung of the implementation system reporting to the Concessionaire, who in turn shall report to IE and the SPIU as per figure 8-1. All reporting by the concessionaire shall be on a quarterly basis, while 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. in JV with | Page (43) Detailed engineering design, safeguards studies and Preparation of bidding documents for prioritized 222.83km rural roads in osun state of Nigeria ESMP (IWO Region)Table 23: Summary of Reporting of Environmental components and ResponsibilitiesSPIU PIU / Independent Engineer Format Site office Item Timing No. Overseeing / Supervision Reporting Compliance CONTRACTOR MOBILIZATION AND SITE CLEARANCE Reporting by contractor to IC for dumping Before start of M1 As required Quarterly As required locations & construction construction and labour camp site Reporting by contractor Before start of M2 to IC for construction As required Quarterly As required construction and labour camp site Target sheet for Tree Before start of After M3 As required As required cutting work cutting Reporting for borrow Before start of M4 As required Quarterly As required areas construction CONSTRUCTION PHASE After Target sheet for As per C1 As required Monitorin As required Pollution Monitoring Monitoring Plan g Before start of C2 Top soil Conservation As required Quarterly As required work OPERATION PHASE After Target sheet for During O1 As required Monitorin As required Pollution Monitoring Operation g After After Redevelopment of completion of O2 As required Monitorin As required Borrow Areas usage of Borrow g Area After During O3 Survival Rate of Trees As required Monitorin As required Operation g in JV with | Page (44) Detailed engineering design, safeguards studies and Preparation of bidding documents for prioritized 222.83km rural roads in osun state of Nigeria ESMP (IWO Region)2.4 ENVIRONMENTAL CAPACITY BUILDINGTraining of staff will be done at a number of levels. Some short-term training is required for the Environment Manager, other staff members of the Environment Unit and the contractor staff to raise their levels of environmental awareness. The training can be conducted by either some external agency or through the help of in-house expertise of the SPIU and the consultants and help of Federal Ministry of Environment and World Bank. In the long-term training, special environmental issues will be examined and likely solutions provided to the Environment Unit.The main focus of future training programmes has to be on implementation with special ESMP basis. Since project preparation is drawing to a close, the officials can concentrate on the progress of the project. The following modules can be taken up: in JV with | Page (45) Detailed engineering design, safeguards studies and Preparation of bidding documents for prioritized 222.83km rural roads in osun state of Nigeria ESMP (IWO Region)Table 24: Modules for TrainingS l.

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 MONITORINGThe 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 INDICATORS3.2.1 Ambient Air Quality (AAQ) MonitoringThe 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. in JV with | Page (47) Detailed engineering design, safeguards studies and Preparation of bidding documents for prioritized 222.83km rural roads in osun state of Nigeria ESMP (IWO Region) 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 likeSO2, 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 MonitoringThe 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 QualityWater 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 QualityThe 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 in JV with | Page (48) Detailed engineering design, safeguards studies and Preparation of bidding documents for prioritized 222.83km rural roads in osun state of Nigeria ESMP (IWO Region) 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 COSTA 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. in JV with | Page (49) Detailed engineering design, safeguards studies and Preparation of bidding documents for prioritized 222.83km rural roads in osun state of Nigeria ESMP (IWO Region)Table 35: Environmental Monitoring Plan in JV with | Page (50) Detailed engineering design, safeguards studies and Preparation of bidding documents for prioritized 222.83km rural roads in osun state of Nigeria ESMP (IWO Region)Environ Institutional Responsibilities ment Project Compo stage Parameters Standards Locations Frequency Implementation Supervision nent Contractor Once in a season Plant site, and at through approved Constr PM g /m3, PM for 2 seasons 10 μ 2.5 locations of baseline monitoring IE & SPIU u-ction g/m3, SO , NO , CO (dry, wet ) for 20 μ 2 X FMEnv/State monitoring agency/Lab months Ministry of Air Environment Contractor Once in a season through approved Operat PM g /m3, PM At locations of baseline for 2 season in a 10 μ 2.5 monitoring IE & SPIU ion g/m3, SO , NO , CO monitoring year for the first μ 2 X agency/Lab 5 years.

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 in JV with | Page (62) Detailed engineering design, safeguards studies and Preparation of bidding documents for prioritized 222.83km rural roads in osun state of Nigeria ESMP (IWO Region) 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. in JV with | Page (63) Detailed engineering design, safeguards studies and Preparation of bidding documents for prioritized 222.83km rural roads in osun state of Nigeria ESMP (IWO Region)Annexure 1.3: Guidelines for Existing Quarry ManagementThe Contractor will finalise the locations from the list given by Consultant's for procuring materials.
