ECC Compliance Monitoring for the Atimonan One Energy 2x600MW Coal-Fired Power Plant Project

In 2018-2019 and 2020-2021, Aperçu Consultants conducted the environmental monitoring program (EMoP) for Atimonan One Energy (A1E). The EMoP was done to assess the impacts of the 2x600MW Coal-Fired Power Plant Project on Barangay Villa Ibaba, Atimonan, Quezon and the surrounding environment. Aperçu Consultants conducted quarterly monitoring for the water quality, marine ecology, ambient air and noise quality, and soil quality for contamination assessment. Semi-annual monitoring was done for terrestrial fauna ecology and annual monitoring for terrestrial flora ecology. 

Water Quality

The water quality of surface water, marine water, and groundwater were assessed and compared against the DENR standard (where applicable) and previous monitoring measurements. Parameters measured for water quality included: biochemical oxygen demand, chloride, color, dissolved oxygen, fecal coliform, nitrate, pH, phosphate, temperature, total suspended solids, salinity, total dissolved solids, sulfate, total coliform, turbidity, oil and grease, Cr+6, Pb, Cd, Hg, and As.

Marine Ecology

Various stations in Lamon Bay were assessed for the abundance, dominance, density, percent cover, species richness, and biomass of the plankton, corals, fish, and benthos communities. The findings were compared to previous monitoring reports to assess the impacts of the coal-fired power plant on the marine ecology of Atimonan. 

Ambient Air and Noise Quality

The ambient air quality parameters measured were: sulfur dioxide (SO2), nitrogen dioxide (NO2), total suspended particulates (TSP), and PM10. Heavy metals such as lead (Pb), cadmium (Cd), mercury (Hg), and arscenic (As) were also monitored. Data was gathered at multiple locations within and around the project site.

Soil Quality for Contamination Assessment

The stations established during the impact assessment study were reassessed to check for any contaminants such as oil, diesel, ash, and wastewater that may have originated from the coal-fired power plant. The soil was also assessed for pH, Cd, Cr+6, Pb, As, and Hg.

Terrestrial Fauna Ecology

Three major terrestrial vertebrate groups (mammals, birds, and herpeto-fauna) were assessed for species richness, diversity, abundance, and endemicity. All sampling stations were the same ones assessed during the first ECC compliance monitoring on A1E.

Terrestrial Flora Ecology

Terrestrial flora was assessed for ecosystem stability, productivity, growth and reproductive performance. Specific parameters measured were: population counts, density, occurrence, frequency, dominance, diversity, evenness, abundance, importance values, and species observed. Any presence of natural and anthropogenic disturbances were also noted.
