Abstract

Environment management has been widely applied by policy makers and relevant authorities particularly in industry sector. 111e objectives of this research arc to investigate and determine the environmental and operational perfomlances of a coal-fired power plant Sarawak, and to determine and recommend the impacts of landfill ef1lucnt Ql,;cnar~,e on water quality of Batang Kemc;na and the siting (selection of location) of Maskai Landfill's effluent discharge point, respectively. The parameters are air quality, generating efficiency, power availability and reliability for the first case study. The envirorunental parameters are air quality parameters which include total suspended particulate, particulate matters up to 10 11m in size and sulfur oxides. 111emlal Efficiency and Equivalent Availability Factor were selected as parameters for generating efficiency and availabilily. For reliability, the parameters arc Equivalent Unplanned Outage Factor and Equivalent Planned Outage F actor. Overall findings show (hat better perfonnance was recorded on environmental suggesting more were put on regulatory concerns to ensure high environmental compliances. This case study also demonstrates some relevant toward treating operational improvement as equally significant and benef1cial efforts lor economic gain and environmental enhancement The second ca.'iC study inclucles physicochemical as well as metals parameters such as DO, BODs. uBOD (represented as fast-BOD in QUAL2K), NH,-N, NO,-N, total suspended solids (TSS), lead (Pb), arsenic (As), cadmium (Cd), mercury (Hg) and nickel (Ni). spatial modeling res1:!I!s illustrated the land till leachate discharge would not significantly deteriorate the water quality of both Sg. Besai and Btg. Kelllcna during normal operations either under nonnal or low now conditions (Scenarios 1 and However, leakages or untreated and sudden release of leachate (Scenarlo 3 and Scenario 4) would certainly result in serlous contamination of these flvers as the concentrations of water quality parameters would degrade to Class lllV. This case study suggests Sg. Sesalak as the immediate stream to receive the leachate before it is subsequently channeled to Btg. Kemena. It makes recommendations in the effort to have a more implementable measures for managing Btg. Kemena river system. This work also defines a coordinating structure in aligning key roles and responsibilities of relevant stakeholders involving in environmental management of energy industrial in Sarawak.
