OBJECTIVES & TERMS of REFRENCE THE OF THE PIA Studies

OBJECTIVES

Provision of instrument for establishing any activity that may likely or to a significant extent affect the environment adversely by the New Project.to promote the implementation of appropriate mitigation measures / policy that would lead to reduction of the negative environmental impacts.To encourage the development of procedures for information exchange, notification and consultation between the Company, NESTLE and other stakeholders wherever the New Project operations are / may likely to have significant adverse effects on the neighbouring establishments, towns and villages.To assist the company, NESTLE, in the establishment and achievement of long term management objectives of minimizing environmental risks and associated financial losses.

To ensure that the New Project does not lead to non compliance of the existing internal, NESTLE (where available), and statutory environmental laws and regulations.

TERMS OF REFERENCE

Measurement of the air quality and noise level within the TPP area.

Collection and analysis of liquid effluent, gaseous emissions from the TPP plant.

Establishment of compliance of the TPP with the standard limits set by FMENV / NESREA for gaseous emission, liquid effluent and noise level.

Assessment of the Safety, Health and Environmental (SHE) policy of Nestle as it relates to the TPP operation..

Assessment of the plants internal environmental management system to implement the above policies.

Examining the sanitary and aesthetic conditions of the TPP

Examination of sources of waste, existing waste disposal methods and waste reduction options available in the plant and specifically for the TPP.

Proposing appropriate and practicable recommendation on i - vii

Preparation of Post - Impact Assessment Studies Report for the TPP operation and submission to the appropriate Regulatory Authority

CHAPTER TWOPLANT DESCRIPTION

NATURE OF PLANTTri-generation Power Plant (TPP) is an integrated power (Electricity), Hot water (Heat) and Chilled water (Cooling) System facility.THE PLANT LOCATIONThe Trigeneration Power Plant is located inside the Nestle Agbara Factory Complex which has been in existence for over thirty years. It occupies approximately 2,713m2 of land, which is just about 1.4 % of the total area 192,500 m2 occupied by the factory.

THE PROCESS DESCRIPTION Natural gas or diesel is feed into the two (2) dual fuel Wartsila Reciprocator Engines. The gas or diesel is processed and converted by the engine to generate electricity as the main output. The heat generated as a bye product is circulated via a heat exchanger in jacketed pipes to supply hot water.The waste heat from the system exhaust is recovered to feed the absorption chiller to produce chilled water. Schematic Diagram of the Tri - generation Plant is shown below.

PLANT OPERATION AND PERSONNELThe TPP is managed by the Agbara Factory Project Department headed by the Project Manager.A model shift on duty consists of a control room operator, a mechanical technician, an Electrical technician. In addition there is always a mechanical and an Electrical team on general day duty.
