Monitoring Activities for the 210 MW Mindanao Power Plant

Apercu’s main client since the start of its operation is the STEAG State Power Inc. (SPI) 210 MW Mindanao Power Plant located in a 55-hectare area along Macajalar Bay, within the PHIVIDEC Industrial Estate Brgy. Balacanas – San Martin, Villanueva, Misamis Oriental. Apercu conducted all environmental monitoring in the MPP from 2003 until early 2010. The following are brief descriptions of the environmental monitoring conducted:

  • Ambient Air & Noise Monitoring – The frequency of sampling in the 5 stations is for a 1-hour averaging period twice a day (morning & afternoon) weekly. The stations, additionally, were monitored for a 24-hour averaging period once a month.
  • Water Quality Monitoring – Monitoring of water quality in the vicinity of the power plant include groundwater, freshwater and marine environs. Two (2) groundwater stations, one freshwater station (Tagoloan River) and 3 marine stations (Macalajar Bay) were sampled on a monthly basis.
  • In plant Water Quality Monitoring – Water samples and/or effluents were collected from the boreholes which were monitored on a quarterly basis and the leachate from the ash disposal area, the waste water treatment plant, the multifunction retention basin and the Sewage Treatment Plant which were monitored on a monthly basis.
  • Quarterly Marine Monitoring – The marine environment in the immediate vicinity of the power plant site was characterized by the presence of corals and associated reef fish, seagrass, seaweed, soft bottom fauna and plankton communities. Additionally, the surfaces of the pier piles of the jetty harbor corals and other benthic fauna that in turn serve as food sources for fish. The status of these marine resources was assessed on a quarterly basis.
  • Quarterly Stack Emissions Sampling – Stack emissions sampling were conducted on the power plant’s 2 boilers and 1 stand-by generator set. The parameters sampled include particulate matter, sulfur dioxide, nitrogen dioxide, carbon monoxide, oxygen and mercury. The boilers were sampled for all the enumerated parameters. The generator sets were sampled for all parameters except mercury.
  • Annual Environmental Audit – The Audit Team reviewed the ECC, the EIS and formulates a list of commitments and stipulations relevant to the audit period. Visits to the site, the resettlement area and areas where SPI’s livelihood and environmental projects are on-going were conducted. Key informant interviews were conducted during the site visits, as required.
  • Annual Public Health Monitoring – The Rapid Epidemiological Assessment framework by Douglas Stockman was used for the annual survey. This method looked into the demographics, water and sanitation, food preparation and nutrition, resources, health and endemic diseases of the local community. The abovementioned information is vital for determining the health status of individuals in the community and for assessing the public health concerns of the affected community.

Ambient Air and Emissions Quality Monitoring for the Filminera Power Plant in Masbate (2011)

Monitoring activities for ambient air quality and noise for Masbate Gold Project (MGP) were conducted in April 2009 and October 2010. The MGP of Filminera Resources Corporation is located in Brgy. Puro, Aroroy, Masbate. One of the major facilities of the mine site is a 30 MW Power Plant, which supplies sufficient power to the mine site. MGP maintains and operates five units of Wartsila generator sets. The emission tests for the five units of generator sets were undertaken by Apercu as part of the annual emission monitoring requirements. Ambient air quality and noise monitoring were also undertaken to assess the existing air quality of areas in the vicinity of the power station. Ambient air quality and noise measurements were taken at 7 sampling stations for 1-hour monitoring period. Three of these stations were monitored for 24 hours.

Beach Sediment Characterization Study for the Mindanao Coal-Fired Power Plant of Steag State Power Inc. (2005)

In 2005, Apercu conducted a Beach Sediment Characterization Study for the 210 MW Mindanao Coal-Fired Power Plant of Steag State Power, Inc. in Villanueva, Misamis Oriental. The study aimed to provide a baseline characterization of the sediments samples taken from the beach of the SPI property up to two kilometers towards Tagoloan River and determine source of any pollutant sediments, if present. Analyses conducted for the study included:

  • Petrographic and Mineragraphic Analyses
  • Geochemical and Structural Analyses
  • Scanning Electron Microscopy
  • Pollutant Level Determination

Development of a Predictive Emissions Monitoring System for the Bauang Power Plant (2006)

The Bauang Private Power Corporation commissioned Apercu to conduct a study to explore means of bringing BPPC’s 225 MW Diesel-Fired Power Plant into compliance with the PCAA-IRR emission standards and Continuous Emissions Monitoring System (CEMS) provision at the least cost. A Predictive Emissions Monitoring System (PEMS) software program was developed utilizing existing historical data from the plant’s operations. The reliability and value of PEMS as an alternative to CEMS was established by the study and available options and cost-effective measures for reducing pollutant emissions were determined. A cost benefit analysis of the various options was included in the report. A Compliance Plan was also developed based on the results of the study.

EIA for 100 km CALABARZON Natural Gas Transmission Pipeline Project for First Gas Holdings Inc. (2004)

An Environmental Impact Statement was prepared by Apercu for a proposed Calabarzon Natural Gas Transmission Pipeline Project. The pipeline was to originate from the Onshore Gas Treatment Plant (OGP) of Shell Philippines Exploration BV (SPEX) in Tabangao, Batangas City, would traverse Batangas, Cavite and Laguna and end at the Sucat Thermal Power Plant in Muntinlupa City. The highlights of the study were as follows:

  • 100 km long underground pipeline
  • Social engineering of 14 cities and municipalities
  • Water ecological assessment of 12 creeks/rivers and 3 major basins
  • Engineering, geological and geohazard assessment report (EGGAR)
  • Traffic Study
  • Landslide Studies

The project was issued an ECC in April 2004 by the DENR Central Office. For an overview of the EIA system, please visit our Services page.

Integrated Environmental Risk Assessment for the Sta. Rita and San Lorenzo Natural Gas Power Plants (2007)

Apercu undertook an Integrated Environmental Risk Assessment for the 1000 MW Santa Rita Power Plant and the 500 MW San Lorenzo Power Plant owned by both First Gas Power and FGP Corp. Both power plants are located in a contiguous property in Batangas. The study followed the general framework for risk assessment. In addition, the following scope and coverage established by First Gas were also covered:

  • Risk screening activity including all bulk and non-bulk substances used, handled or stored at the power plants
  • Consequence analysis based on actual plant conditions, actual hazardous substance properties and meteorological data
  • Application of valid consequence scenarios and endpoints
  • Use of appropriate model for consequence analysis, and
  • Generation of consequence hazard zone maps

Contour maps were developed to show the potential impact areas for:

  • Thermal Radiation forecasts
  • Flammable Threats
  • Overpressure Threats
  • Explosion Overpressure Injuries
  • Toxic Cloud Threats
  • Toxic Vapor Cloud Fatalities
  • Oil Spill Forecast Trajectory

Reports were generated both for internal and regulatory purposes. For a backgrounder on ERAs, you may visit our Services page.

IEE for 12 MW Rice hull/Coal power plant for Bataan 2020 (2007)

Apercu prepared an Initial Environmental Examination (IEE) Report for Bataan 2020 Inc. in 2006. The Bataan 2020 project is a 12.5 MW Rice Hull Power Cogeneration Project in its paper mill plant compound in Samal, Bataan. A detailed assessment of the probable impacts of the project was undertaken. Foremost of this was the conduct of air quality modeling to assess the impacts to ambient air. Air quality and deep well water quality assessment were also conducted, as well as flora and fauna surveys. A public consultation was also conducted and was attended by DENR representatives, the Proponent, the preparers and stakeholders. Other key issues related to the power plant development were considered with significant impacts being identified for each phase of the project. Appropriate mitigation measures for the identified impacts were then formulated. ECC was acquired in 2007
