Treasure Steel Corporation (TSC) operates the largest steel billet plant in the country at a current annual production of 300,000 MT. The plant is located in the compound of the former National Steel Corporation in Sitio Nonucan, Barangay Ma. Cristina, Iligan City, Lanao del Norte. TSC proposes to build and operate a 1000-MTPD blast furnace facility to produce pig iron using local iron ore for its billet plant. Apercu conducted an air dispersion modeling, which is a mathematical simulation of the transport, dispersion, and transformation of pollutants in the atmosphere. The air modeling conducted focused on the stack serving the blast furnace facility for SO2, NOx, CO, TSP, and PM10 emissions. To quantitatively describe the dispersion of the thermal effluents from the plant and the levels of water temperature, a thermal plume modeling was also conducted.
Apercu was commissioned to conduct a habitat assessment within the vicinity of the 1,200MW KEILCO Combined-Cycle Power Plant in Brgy. Ilijan, Batangas City. The study examined the status of the benthic communities and their associated fish assemblage in the intake structure, supporting columns of the jetty, and the Giant Clam reserve area. A rapid survey of the beach in the vicinity of the plant was also conducted. The report included recommendations on how to improve the beach area to make it more suitable for the nesting activities of hawksbill turtles that have been observed in the area over the past years. Additionally the underwater video documentation of the habitat assessment was developed into a 15 minute Video IEC material showcasing the marine biota in the vicinity of the power plant. Photos of the various species of corals, fish and other benthic organisms observed during the survey were also compiled into a coffee table book, for use also as an IEC material.
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.
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.
In preparation for the implementation of the second phase of Accion Contra El Hambre’s project, Apercu was engaged to conduct an Environmental Capacity Study of Land and Marine Resources. The study covered fifteen (15) barangays in Vigan and two (2) barangays in Caoayan. The three major components and scope of work of the study were as follows:
- Marine Resource Survey (Oceanography, Coral Communities, Associated Reef Fishes, Fish Catch)
- Land Resource Study (Land Use, Vegetation, Wildlife, Soil Analysis and Capacity)
- Social Resource Scanning (Focused Group Discussions for Livelihood Options, Workshops)
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
Apercu carried out Bathymetric Mapping of Macajalar Bay in Misamis Oriental to confirm ocean floor depths in the jetty area for docking of coal delivering ships. The area was surveyed using an echo sounder connected to a mapping software and a Global Positioning System (GPS) unit. The final product was a 3D map of the bathymetry in the vicinity of the power plant pier.
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.
In 2006, Petron Corporation implemented the PetroFCC Project to enable production of at least 140,000 MT per year of polymer grade propylene product by converting an existing Thermofor Catalytic Cracking Unit (TCCU) into a high propylene yield producing Fluidized Catalytic Cracking Unit (FCCU). The project is located inside the existing refinery compound in Barangay Alangan, Limay, Bataan. Since the PetroFCC is an expansion within an already existing operation, Apercu prepared an Environmental Performance Report and Management Plan (EPRMP). The EPRMP included the documentation of the actual environmental performance of PBR based on current and past environmental management measures being implemented. The detailed comparative description of the proposed process modifications, corresponding material balances and the pollution control devices were also discussed in the report. Since the activities in oil refinery operations include handling substances classified as combustible and/or flammable, an Environmental Risk Assessment was also undertaken to assess the likelihood or probability of a hazardous accident. The PetroFCC Project ECC was secured in November 2006.

A year after the PetroFCC Project, the Refinery Division of Petron Corporation invested in a benzene, toluene and xylene (BTX) Project. The BTX Project involves both the revamp of existing process units as well as the addition of a new unit. The EPRMP scope essentially covered updating the data provided for the PetroFCC EPRMP. Since the ECC issued for the PetroFCC required the conduct of a full Quantitative Risk Assessment (QRA) of the existing refinery, as well as future projects, Petron commissioned a foreign entity to undertake the QRA. Preliminary results from the QRA were included in the EPRMP report prepared by Apercu. The ECC was acquired in July 2007.
