What is an ESIA?
An ESIA is a study to identify and assess the possible environmental and social impacts associated with a proposed development – in this case the quarry and cement plant project. In order to commence with the Project, an ESIA must be done. This ESIA must be done in accordance with the relevant in-country legislation as well as international good practice guidelines such as the IFC’s Performance Standards.

An ESIA process typically aims to answer five key questions regarding the proposed development. These questions are illustrated in Figure 1 below.

Southport Cement Limited, a wholly Nigerian owned private limited liability company, is planning to develop, construct and operate a cement plant in Ewekoro Local Government Area (LGA) within Ogun State, Nigeria. This cement plant and quarry is being developed to meet the growing demand for cement locally as well as markets in Northern Nigeria.

The planned facility requires an Environmental and Social Impact Assessment (ESIA).

Project Location
The cement plant and limestone quarry will be located on a 580 hectare and a 614 hectare sites respectively both adjacent to Onigbedu Community and the near Itori in Ewekoro LGA, Ogun State, Nigeria (refer to Figure 2 below). Furthermore the plant will be located approximately 10 km from the Dangote cement plant and 14 km from the Lafarge Wapco cement plant.

Proposed Project description and facilities
Southport is in the process of acquiring the land for the quarry and the cement plant.

The capacity of the plant is based on a rated kiln output of 5.000 t/d clinker, providing a nominal production capacity of 1.68 Mt/year CEM I and 2,13 Mt/y ear CEM II (CEMI and CEM II are types of cement). The raw materials for the plant will be sourced from the limestone quarry adjacent to the proposed plant location.

The plant components will comprise:

  • Intake hopper and silo;
  • Raw mill feeding equipment;
  • Raw mill;
  • Raw meal blending and storage silo;
  • Kiln with calciner and pre-heater (dry process);
  • Clinker cooler;
  • Clinker transport and clinker silo;
  • Exhaust gas de-duster; and 
  • A bagging plant.

Water will be secured via onsite boreholes it is anticipated that the cement plant will use approximately 50 000 l/h.

The quarry will consist of various earth moving and blasting equipment with a conveyor system to transfer raw limestone to the plant for milling and processing.

The plant will be powered by a small captive power plant comprised of a number of power generators fuelled by gas or diesel.

A new access road will be built from Itori on the A5 to the Project Site. The new road will be of 5 m wide asphalt cover on 35 cm compacted gravel sub-base and 1.5 m shoulders along both sides. The road will be used to transport construction materials and equipment as well as the finished product once the plant is operational.

The Project will employ both skilled and unskilled labourers. Workers will housed in accommodation near the Project site.

Project Activities
The Pre-construction and Construction Phase activities will include the construction of the cement plant and associated infrastructure, and development of the quarry. The preparation and clearing of the site, will be followed by the construction of access roads, cement plant and ancillary facilities. Finally, the transport installation of equipment, including fuel and water storage facilities will take place.

During the Operational Phase the cement plant and quarry will be operated on an 8 hour, 7 days a week basis. There will traffic bringing supplies to the cement plant and the finished product leaving the plant during commercial operations. General maintenance and servicing of the facility will also take place on a regular basis.

Decommissioning Phase
During the decommissioning phase all project infrastructure will be removed and the site will be returned to its previous state. A mine closure plan will be compiled for the quarry.

Project Schedule and Life of Mine
The construction of the cement plant and development of the quarry is estimated to take approximately 25 months. Site preparation is expected to begin in 2017 and with production expected to begin in 2019. The life of the mine is expected to be 40 years.

Potential benefits
The construction of the plant will meet the growing demand for cement in Nigeria, in particular local areas as well as markets in the north of the country. The plant will increase industrial activity and create jobs outside of Lagos.

Potential Issues
A cement plant can affect the environment by its construction and its operation. These effects or impacts can either be temporary or permanent. Below are the potential issues or impacts which could result from Project.

  • Air Quality: Air pollutants from the operating the cement plant and mining at the quarry could decrease ambient air quality, therefore the plant and quarry will need to be undertake pollution control measures to reduce emissions.

  • Noise: Operating the power plant could increase noise levels in the area and may be a concern particularly to nearby communities.

  • Vegetation: Vegetation Impacts can be of two basic types, including direct impacts of vegetation removal and damage during construction and indirect impacts on vegetation from influx of people into the area, habitat fragmentation, and disruption of ecosystem services.

  • Soil: The construction of the plant and mining at the quarry could lead to erosion and impact soil resources in the area.

  • Water Quality: Pollution and pollutants discharged from the plant can result in adverse surface water and groundwater quality impacts.

  • Fauna: Impacts on habitats could create a chain of wildlife impacts. Impacts on local wildlife could occur when their habitat and source of food is removed or damaged.

  • Resettlement Action: Due to the location of the plant it is possible that physical and economical resettlement may be required.

  • Community Health and Safety: The Project could result impacts on communities due to changes in livelihoods, influx of people from other areas, and sociocultural changes to local communities.

The ESIA Process
Under the Nigeria Environmental Impact Assessment (EIA) Act (CAP E12, LFN 2004), Southport Cement is required to submit an Environmental and Social Impact Assessment (ESIA) in order to construct and operate the cement plant and quarry. Southport Cement has appointed Environmental Resources Management (ERM) in conjunction with Nigeria-based EnvironQuest Nigeria Limited and Translantic Development Limited (TDL) to undertake the ESIA for this project.

The ESIA will describe the project, the affected areas, assess the likely positive and negative impacts of the project and describe the proposed plans to manage these impacts. The ESIA Report, along with comments received from stakeholders will be submitted to the Federal Ministry of Environment (FMEnv) who will decide whether or not to authorise the proposed project.

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. The ESIA process is presented in Figure 3

Baseline studies for the ESIA will include, but not be limited to assessment of the following:

  • Terrestrial Soils and Geology;
  • Surface and Ground Water;
  • 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);
  • Livelihoods and Micro-Economy, Key Livelihoods, and Employment;
  • Transport and Access;
  • Social Infrastructure and Cultural Sites; and
  • Community Health and Safety.
