Background Information Document (BID)
This Background Information Document (BID) provides information to assist stakeholders to participate in the Environment and Social Impact Assessment (ESIA) and environmental authorization process for the proposed 100MW Solar Power Plant Project at Bungudu L.G.A., Zamfara State (The Project);
What is the ESIA About?
Basically, the ESIA is the process of identifying, predicting, evaluating and mitigating the physical, biological, social and other relevant effects of the proposed project prior to major decisions being taken and commitments made.
In compliance to administrative/statutory guidelines/provisions of regulatory bodies, and as part of the licensing requirement to generate power in Nigeria, the Federal Ministry of Environment (FMEnv), the National Electricity Regulatory Commission (NERC), Nigeria Bulk Electricity Trading Company (NBET), Transmission Company of Nigeria (TCN), and in accordance to the Environmental Impact Assessment (EIA) Act CAP E12 LFN 2004 (formerly EIA Act 1992), the Electric Power Sector Reform Act, 2005, Nigerian Electricity Supply and Installation Standards Regulations, 2015, relevant/related National and International Regulations, as well as Good Utility Practice in the Nigerian Electricity Supply Industry, Yutai Li Nig. Limited (the project-proponent) has commissioned Richflood International to conduct an Environmental and Social Impact Assessment (ESIA) for the proposed 100MW Solar Power Plant (Constructing a Photovoltaic Technology) Project at Tazame village in Kwatarkwashi Community, Bungudu Local Government Area of Zamfara State.

Components of the PV-Plant’ Project
The project is to utilize solar energy to generate power with a capacity of 100MW to be connected to the national grid in Nigeria. The proposed (photovoltaic plant) project consists of the following main components:
- Site Preparation: Site preparation involves the Site Survey and Clearing. During Site Survey, the boundaries of the location shall be surveyed and the outlines indicated by means of coloured survey pillars.
- Civil Works: Civil Works entails the set up of basic infrastructure done before the installation of the solar panels. Plenty of Civil Work is required for ground based solar panel installations which includes the levelling of the site, building access roads, trenches for cabling. Foundation works anchoring the solar panels.
- Mechanical Works: Once the civil works are completed, mechanical works shall commence at site. Mechanical installations are required for mounting the solar panels and according to the required tilt angles. The structures required for installing solar panels can be of galvanized steel, hot galvanized steel or anodized aluminum. Ground anchors shall be used for mounting structures on flat terrain. The average length of the anchor is 1 to 1.6 meters. Concrete foundations shall be constructed in order to provide a strong base to the installations.
- Staff Strength: The project will need personnels/workers for security check and technical operations, professional persons for maintenance and plant engineers to administrate the daily operation/services, thus Staff Strength at the project facility will be an estimate of 200 workers.
- Access Roads: The proposed project site is accessible through the only/main road of Zaria – Gusau Highway; with a distance of 150m to the main road. Gusau – Zaria highway serves as a major access road to the study area. This express road links to the neighbouring states of Sokoto, Kebbi, Katsina, and Kaduna.
- Ancillary Facilities: The layout of the proposed project site will accommodate the following facilities: Eight Camps, One Store Room, Clinic Facility, and a Borehole.
- Connection to the grid: Routing energy generated from solar field (100MW) to the national electricity grid; through connection of an associate transmission line of 3km distance.

Objectives of the ESIA
The objectives of the ESIA for the project site are to:
- Provide information and evidence required for developing an Environmental Impact Statement for the project site;
- Establish baseline information for the project site.
- Identify associated/potential impacts of the project in the area;
- Recommend preventive, mitigative and control measures for the identified potential/associated adverse impacts of the project; and
- Develop an effective Environmental Management Plan (EMP) for the lifetime of the project.
POTENTIAL AND ASSOCIATED IMPACT ASSESSMENT
Environmental Impact Indicators
The environmental impact indicators for the study are easily observable parameters that will indicate change/deviation, which can be used to monitor the various environmental components.
The primary Biophysical Indicators for the on-going impact assessment are the following:
- Climate and meteorology;
- Air quality;
- Geology and geomorphology;
- Soils and soil erosion;
- Drainage patterns and flooding;
- Unique physical features; and
- Vegetation including economic trees and crops.
The primary Socio-Economic Indicators for the on-going impact assessment are the following:
- Land use;
- Employment and income;
- Community population and ethnicity;
- Community relations; and
- Services (e.g water and electricity supply).
The main environmental issues are as follows:
All construction and operation activities that are likely to cause environmental and social impacts will be identified, and evaluated to assess their magnitude, duration, and potential receptors.
The activities, which have the potential to cause impacts on surrounding environment and receptors during the Construction of the power plant, are identified as:
- Site preparation;
- Transportation of construction material, machinery, heavy machinery/ equipment for the power plant by road
- Excavation of equipment foundations and installation of power plant components;
- Laydown areas for temporary use during construction phase;
- Storage and handling of hazardous materials, waste and wastewater; and
- Accommodation and transportation for the construction workforce
During the construction phase, contamination of soil, sediment and ground water may result from potential leaks and spills of oil, lubricants, or fuel from heavy equipment, dust and exhaust emissions, clearance of vegetation, improper handling of sanitary effluent, or chemical/fuel storage and sanitary and construction wastes.
Some of the social impacts due to the operations of the Project are: Employment Generation and In-Migration of Skilled workforce, Demand for lodging, housing and civic services, Increments in cost of living, Opportunity for local transporters and Risks of industrial accidents and fatalities to workers. The impacts as employment generation, demand lodging, housing and opportunity for local transporters would be positive where as other would be creating negligible impacts.
Baseline studies for the ESIA will include, but not be limited to assessment of the following:
- Fauna and Flora;
- Air quality and Noise;
- Demographics, Population, Ethnicity; Language, Vulnerable Groups, Education
- Socio-Cultural Institutions, Leadership Patterns, Government Administration, and Other Institutions (NGOs/CBOs);
- Terrestrial Soils and Geology;
- Surface and Ground Water;
- Livelihoods and Micro-Economy, Key Livelihoods, and Employment;
- Transport and Access;
- Social Infrastructure and Cultural Sites; and
- Community Health and Safety.
The ESIA process aims to identify all the potential impacts of the proposed project, assess the significance of the impacts, and to present measures to mitigate these impacts.
