An Environmental Impact Statement (EIS) was prepared for Atimonan One Energy’s (A1E) application for an Environmental Compliance Certificate (ECC) of its proposed 2x600MW Coal-Fired Power Plant. The project is located in Barangay Villa Ibaba, Atimonan, Quezon and has approximately 139.31 kilometers in land area. The project is a response to the country’s growing demand for electrical power, especially in Luzon.
To prepare for the EIS, Aperçu Consultants Inc. conducted the following activities:
Land Use and Classification
Land use data from the Comprehensive Land Use Plan (CLUP) of Atimonan classified the location of the project site as mainly coconut and brushland, designated for agriculture use. The Sangguniang Bayan passed two ordinances to reclassify 70 hectares for industrial use for the project. A Foreshore Lease Agreement application was also filed for the 9 hectare foreshore area belonging to the project site.
Geology and Geomorphology
An assessment of the geology of the project site accompanied with a study of hazard maps was conducted to identify the potential impacts that may occur within the project location induced by geologic hazards, particularly those associated with mass movement, earthquakes, and flooding.
Soil within the project site was classified according to the soil map of Quezon Province. To determine soil quality, samples were collected from sampling stations within the project site and its vicinity and analyzed. Impacts to the soil quality were identified.
Sampling was conducted for the collection of floral data within the impact area. Vegetation was delineated according to their land use and the plants were identified and classified. Assessment of the fauna in the impact area was also conducted, which included birds, mammals, amphibians. Impacts to the flora and fauna during the pre-construction, construction, and operational were identified and the mitigating measures and management plan were established.
To determine the baseline conditions of the project area before the proposed project, information on the drainage morphology, hydrogeology, rainfall and streamflow measurements, spring and well point inventory, water availability, aquifers, and major water users were collected and summarized. Flood and drought occurrences were also studied.
Collecting information on the tides, bathymetry, and the conduct of a hydrographic survey are used to establish the baseline parameters within the impact area. Thermal plume modeling was done to assess the possible impacts of the project.
The baseline data of the water quality in the project site for the impact determination of the project were determined based on the parameters of the water samples from marine, freshwater and groundwater sampling stations collected from the project site and its vicinity.
Sampling stations were established in the rivers found near the project site where the habitat was assessed and plankton, macrobenthos, and fish samples were collected and identified. The impacts of the project to these organisms as well as the water quality of the river were determined and corresponding mitigating and management measures were established.
Assessments for the coral reef, fish communities, as well as marine water and sediment samples collected from sampling stations for benthos and plankton identification were conducted. These marine resources were characterized. Occurrences of red tide cases within the impact area were also studied. The threats to the existence of these species and other marine resources due to the project were identified and mitigating measures were established.
Information on the meteorological conditions at the project site were described and parameters that directly contribute to air pollution and climate change were established. Impacts from the project that affect climate change projections and greenhouse gas emissions were determined.
Ambient Air Quality
Measurement of the ambient levels of criteria pollutants were used to describe the existing ambient air conditions in the project area. Sources of air emissions and existing air pollutant levels were determined. Surveys to determine the pollutants (SO₂, NO₂, TSP, PM10, lead) and trace metals due to coal combustion emissions were conducted. The results were used for air dispersion modeling.
Ambient noise level measurements during the construction and operation phase of the project were described and were assessed by modeling and compared to the guidelines from DENR.
Collection of primary and secondary data to establish the baseline information in the impact area was carried out. Information on the population, gender and age, health, socio-economics, education, nutrition, employment, industry, crime, agriculture, and social services were summarized and perception surveys were conducted. Potential impacts from this information were identified and mitigating measures for the impacts were established.
Environmental Risk Assessment (ERA)
All probable risks and sources of accidents that might come from the project are identified and screened. Risk estimation and probability occurrence of these accidents due to the project are presented and emergency response measures were recommended to combat these risks.
The Environmental Compliance Certificate (ECC) for the project was issued by the Department of Environment and Natural Resources (DENR) in October 2015 with ECC Reference No. ECC-CO-1412-0029. The ECC is available at the following link.
