FOREWORD
PT Supreme Energy Muara Laboh (SEML) plans to conduct "Geothermal Development for Muaralaboh 250 MW Geothermal Power Plant (PLTP) in South Solok Regency, West Sumatra Province." This activity is expected to address a crisis of electrical energy in Indonesia and in particular in West Sumatra, to support the Indonesian government's policy of energy diversification and reduction in the consumption of fuel oil (BBM), reduction of electricity and fuel subsidies, as well as utilization of geothermal resources, which have high economic potential in Muara Labuh.
Geothermal development plans generally include construction and operation of geothermal wells and power plants, construction of supporting infrastructure, and electricity distribution. These activities have potential to cause environmental impacts such as reduced air quality and water quality, biodiversity changes, changes in land use, improved transportation, increased job and business opportunities, and modified public perceptions.
Based on Minister of Environment Regulation No. 05 of 2012 regarding Types of Business Plans and/or Activities Requiring EIA (AMDAL), the proponent plans to conduct the EIA study as part of the environmentsl feasibility study. The EIA study aims to maximize benefits and minimize negative impacts on communities and environment from the proposed geothermal power plant construction and operations.
This document, Environmental Management Plan (RKL), and Environmental Monitoring Plan (RPL), part of SEML commitment to the management of Health Safety and Environmental (K3LL).
It is expected that utilization of geothermal energy by the Muaralaboh 250 MW Geothermal Power Plant can provide benefits to all stakeholders. We would like to thank all those who have contributed to preparation of this RKL RPL document.

CHAPTER I INTRODUCTION
I.1 AIMS AND OBJECTIVES OF RKL-RPL
The Environmental Management Plan (abbreviated RKL in Indonesian) and Environmental Monitoring Plan (abbreviated RPL in Indonesian) compiled in this report are based on the documented prediction and evaluation of significant impacts. The aims and purposes of the RKL RPL report are as follows:
I.1.1 Aims
RKL is an action plan to manage significant impacts caused by the project activity, whereas RPL is a guidance to monitor the results of the environmental management. Thus the RKL RPL document is intended to:
. Develop management plans for the significant impacts identified to comply with the law and environmental quality standards and/or minimize environmental impacts, so as to avoid potential significant negative impacts that may develop and become environmental issues or social issues that may harm various stakeholders,
. Develop monitoring plans to determine the effectiveness of environmental management and to continuously evaluate and improve environmental management.
The RKL RPL shall control and manage any significant issues generated by the project activities, so that these impacts shall not develop into regional, national, or even international environmental issues.
I.1.2 Objectives
RKL RPL main goal is to control impacts to comply with the norms, standards, procedures and applicable laws and regulations. More detailed objectives of RKL RPL document are:
. Ensure that the proposed project of geothermal power plant development at Muara Laboh complies with environmental laws and regulations by managing natural resources to be utilized wisely for the local, regional, and national economic development,
. Manage significant impacts from the geothermal power plant development at Muara Laboh Power Plant to comply with applicable environmental standards and minimize the negative environmental and social impacts,
. Implement environmental management in accordance with the plans set forth in the FS/ Feasibility Study and DED / Detailed Engineering Design (impact mitigation),
. Provide a fund to manage environmental impacts according to the environmental management plans and involving all stakeholders in accordance with applicable laws and regulations,
PT Supreme Energy Muara Laboh I-1 RKL-RPL of Geothermal Developmennt for Muara Laboh Power Plant 250 MW
. Monitor the negative environmental impacts to ensure that the environmental management plan remains in accordance with the applicable laws and regulations,
. Inform environmental monitoring results to project stakeholders as a reference for further evaluation and follow-up plans for environmental management.
Thus all significant impacts and mitigated impacts shall be monitored and controlled to comply with applicable laws and regulations. Mitigated impacts are impacts known or expected since the project planning stage, which are identified in the FS and DED documents, to be managed and controlled. These mitigated impacts do not require further assessment in the ANDAL, but should be clearly stated in the RKL RPL.

III.5 OTHER IMPACT MONITORING
a. Environmental Impacts to be Managed
. Solid waste non industry: solid waste type and quantities collected, transported, disposed at landfill and recycled, . Domestic waste water: Biochemical Oxygen Demand, Chemical Oxygen Demand, Total Suspended Solids and pH, . Hazardous waste types and quantitities, . Spills: spill types and numbers, and quantities spilled.
b. Indicators of Environmental Monitoring Success
. Comply with Minister of Energy and Mineral Resources Regulation No. 045 of 2006 regarding Drilling Mud Requirement and Management,
. Comply with requirements of applicable hazardous management rules (Government Regulation No. 18 of 1999 and Government Regulation No. 85 of 1999).
c. Sources of Impact
. Municipal solid waste, . Domestic waste water from Waste Water Treatment Plant (WWTP), . Drilling wells, sump pits, production wells (during production testing) that potentially generate hazardous wastes and non-hazardous wastes.
d. Data Collection Methods and Analysis
. Measure the amount of solid waste generated by counting the numbers of trucks which carrying solid waste to dispose at landfill, . Collect, prepare, and analyze water samplea from all domestic waste water treatment plant outlets according to PT SEML protocol based on SNI, also conduct in situ measurement of pH, conductivity, and temperature, . Monitor the implementation of Standard Operating Procedures (SOP) for oil spills, . Monitor the implementation of Standard Operating Procedures (SOP) of hazardous waste handling and disposal,
PT Supreme Energy Muara Laboh III-33 RKL-RPL Geothermal Development for Muara Laboh Power Plant 250 MW
. Conduct toxicity characteristic leaching procedure tests for drilling mud, mud waste, and drilling dust.
e. Locations for Environmental Monitoring
. Municipal solid waste landfill,
. Domestic Waste Water Treatment Plant,
. Well location (sump pits and mud waste disposal).
f. Duration and Period of Environmental Monitoring
During construction stage until operation stage:
. Solid waste: every time solid waste is disposed to landfill,
. WWTP: once every month,
. Well location: two times, while drilling and after drilling.
