Aperçu Consultants Inc. evaluated the existing plant conditions and conducted the following activities to prepare for the EPRMP:

Land Module

Land Use and Classification

Primary and secondary data from  surveys were collected and used to reclassify the land use of the area. Previously, the project site was classified as a Built-Up Area in the Comprehensive Land Use Plan (CLUP) of Toledo City but was reclassified as an Industrial Zone through an application for reclassification by TVI. Impacts and mitigation measures because of this reclassification were identified.

Geology and Geomorphology

Information from previous geologic surveys and maps from several potential hazards were collected, reviewed, and used to identify the potential impacts associated with these geological hazards. 

Pedology

Soil analysis from samples taken from the project site was conducted to identify the various potential impacts of the project to the site which considered factors such as sediment sources and riverbank stability. The results of the analysis served as the baseline data for future soil quality monitoring activities in the plant.

Terrestrial Ecology

The biodiversity of the project location’s flora and fauna were surveyed. The distance of the project site with respect to established Important Bird Areas in Cebu were identified. The species were identified via bird-watching, observations, interviews, and literature reviews. The initial baseline environment within the project site was grassland but site development within the project area has altered its floral characteristics, however no major impact resulted from this.

Water Module

Hydrology/Hydrogeology

Information about the drainage morphology, hydrogeology, rainfall and streamflow measurements, surface water and well characteristics, aquifers, and major water users were obtained to  identify the impacts of the project as well as the mitigating and management factor.

Oceanography

Data gathering and analysis, bathymetry surveys, temperature and salinity profiles, water current measurements, hydrodynamic modeling, particle dispersion modeling, were conducted to characterize the oceanography of the area. These were used to assess the potential hazards and permanent impacts of the project such as changes in bathymetry, water circulation, and littoral current, as well as impacts on the coast, water quality, and climate.

Water Quality

Water samples from marine and groundwater sampling stations were collected from the project site and its vicinity and tested for various parameters which served as baseline information for the water quality. This information is used to pinpoint the future impacts of the project to the water quality.

Marine Ecology

A marine ecology survey was conducted to identify the marine habitats (coral reefs, seagrass and seaweed communities, mangrove forests, fisheries) and organisms (planktons, macroinvertebrates, marine mammals) within the impact area of the project site. The threats to the existence of these species as well as the marine resources due to the project were identified and mitigating measures were established.

The baseline geologic, pedologic, topographic conditions as well as current land use of the municipality of Limay was assessed in order to identify critical environmental parameters, assess possible impacts, and identify mitigating measures. 

Flora and Fauna

The flora and faunal biodiversity of the project site was assessed. The conservation status of each species observed was also identified. An emphasis was placed on the avifaunal assessments since Bataan is a declared Bird Sanctuary. Species found within the Petron Bataan Refinery compound were known to have high tolerance to areas with high human activities and high levels of industrial noise. 

Soil and Groundwater Quality Assessment

An Environmental Site Assessment was done for both the Benzene Tank Farm and Old Sludge Pint. Soil and groundwater samples were taken from appropriate sampling sites then shipped to MGT Environmental Consulting Pty. Ltd. in Victoria, Australia for analyses. Soil samples were tested for Total Petroleum Hydrocarbons (TPH) and Monocyclic Aromatic Hydrocarbons. Results from the soil analyses were compared to the DENR Screening Guidelines. Groundwater samples were taken from wells and sampled for TPH, BTEX compounds, and Methyl-tert Butyl Ether (MTBE). Results from groundwater analyses were compared to the DENR Screening Guidelines.

Water Module

Description of the Aquatic Environment

The nearest water bodies surrounding the Petron Bataan Refinery are Manila Bay (east), Limay Bay (north), and Lamao River (south). Previous studies on these water bodies were assessed and analyzed.

Marine Biology

Marine waters adjacent to the Petron Bataan Refinery were surveyed. Marine surveys were representative of the general conditions of the marine ecology in the vicinity of the project site. Benthic communities at risk of being affected by the project’s activities were identified. Spot dives and water sampling was also conducted in selected areas. 

Hydrology

Results from previously commissioned studies by the Petron Bataan Refinery relevant to the EPRMP were analyzed. Among these were the geo-resistivity surveys, pumping tests, aquifer hydraulic characterization, pump rating tests, safe yield estimates, sensitivity analysis, surface water availability, water quality, and status of new wells.

Water Quality

Water quality of the effluents from the sewage treatment facility (STF) and oily wastewater treatment plant (OWWTP) over the past five years were checked to see if it consistently conformed to the DENR standard.

Thermal Plume Modeling

The objectives of this study was to generate a local circulation model for the region of interest and to use the resulting current fields as forcing for the thermal plume model. The areal extent of distribution of warm water from the project’s outfall discharge was also examined. 

Air Module

Climate

The climate of the project was assessed in order to describe rainfall patterns, relative humidity, annual maximum and minimum temperatures, cloud cover, surface winds, sea and land breezes, and cyclone frequency.

The project is expected to address Mindanao’s need for additional energy by 2025.

The proponent for the project, the FGen Tagoloan Hydro Corporation is a subsidiary of the First Gen, created specifically for the Tagoloan Hydropower Project. In addition, the First Gen is considered the leading company in the Philippines in the field of clean and renewable energy and composing 16% of the total installed capacity in the country or 2,959MW. 

Aperçu Consultants Inc. conducted the following activities to prepare for the EPRMP:

Land Module

Land Use, Geology, and Pedology

Data from the municipal Comprehensive Land Use Plan (CLUP) of Impasug-ong was used to determine the land use of the area with relation to the location of the Tagoloan HPP. Information on the slopes and soil types was also collected. The geology of the project area was assessed and potential hazards and hazard-prone areas were identified.

Terrestrial Ecology

The flora assessment of the project site was taken from the Ecological Study and Sustainability Plan (ESSP) of the GHD of the Tagoloan HPP which was conducted through the commission of the FGen Tagoloan. The results of the ESSP were considered in the formulation of the EPRMP. The ESSP assessed the ecological parameters (i.e., density, frequency, dominance, plant diversity, and evenness indices) using the Magurran 1988 formulae, and the vegetation description of the area which includes the taxa richness, biodiversity indices, ecologically important species, and invasive species. This has helped in the development of mitigating and monitoring measures in terms of the possible impacts the project activities may cause to the identified species.

A faunal assessment of avian, mammalian, amphibians, and reptiles in the site were assessed during the dry season. The presence, distribution, and endemicity/conservation status were also identified to provide an assessment of the impact of the project to the identified species which were the basis in the development of mitigating measures and monitoring plans. 

Water Module

Hydrology/Hydrogeology

The hydrology which includes the hydrologic catchment, climate, rainfall, evaporation, streamflow, hydrological modelling was discussed and assessed. The hydrological modelling involved the streamflow and minimum ecological flow of the Tagaloan River which were used in determining the flow scenarios that are to occur to the river. 

Water Quality

Water samples were collected from the project site to be used for the baseline data for water quality to which the impacts of the project will be determined from. The potential impacts based on the results of the parameters for water quality were considered and given mitigation and management measures.

Air Module

Meteorology

The existing meteorological conditions at the project site were collected and assessed to identify which factors may impact the project area.

Ambient Air Quality

The existing ambient air quality in the project area was measured as a baseline to be compared to the ambient air quality standards during the construction and operation phases of the project. Sources of air emissions and existing air pollutant levels were determined.

Ambient Noise

The existing ambient noise levels in the vicinity of the proposed project site were measured and the potential noise impacts during the construction and operation of the plant were determined and compared to criteria values.

People Module

The baseline socio-economic conditions of the municipality were described and Information, Education, and Communication (IEC) programs were conducted to make the community aware of the proposed project. A Social Assessment Study (SAS) was also conducted to establish the economic, political, and cultural significance of the project.

Risks during the construction and operation of the project were identified and evaluated. Assessment studies were conducted to understand these risks and develop suitable mitigation strategies, management and emergency response plans.

The Environmental Compliance Certificate (ECC) for the project was issued by the Department of Environment and Natural Resources (DENR) Region X on 01 October 2012 with ECC Reference No. ECC-R10-1209-0178. The ECC is available at the following link.

EPRMP for Petron Bataan Refinery’s Petro-Fluidized Catalytic Cracking Unit Project (2006)

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.

EPRMP for Petron Bataan Refinery’s Benzene, Toluene and Xylene Project (2007)

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.

EPRMP for Balai sa Laiya and Tivona Beach Resorts (2009)

EPRMP studies were conducted for both Balai sa Laiya Beach Resort and Tivona Beach Resort. These tourism projects are located on the seaside community of Brgy. Laiya and Hugom in San Juan, Batangas. These 2 tourism projects have been operating without an ECC, hence, an EPRMP study was conducted for these resorts. The surroundings and existing environmental management measures being implemented by the resorts were characterized. Because the projects are situated in a coastal tourism area, many mitigation measures were added to diminish the effects of the development on the surrounding area. The ECCs for both the project sites were acquired in 2009.

EPRMP for Petron Bataan Refinery’s Upgrade Projects (2010)

An Environmental Performance Report and Management Plan was prepared for the Petron Bataan Refinery Upgrade Project. The Upgrade Project will convert PBR into a full-conversion refinery, the only one in the Philippines.

The upgrade involved 3 components:

  • a. Refinery Master Plan II involving the installation of new equipment for several process units ( e.g., mercaptan oxidatin unit, vacuum distillation,coker, hydrotreater, sulfur recovery unit and the waste water treatment plant)
  • b. Additional Tank Farm; and
  • c. 140 MW Refinery Solid Fuel Fired Power Plant.

The project is located in the existing Petron Bataan Refinery in Brgy. Alangan, Limay, Bataan. The major hurdles for this project involved the clear and concise comparisons of the base case against the various upgrades, and the impact of these on waste streams and environmental management measures of the refinery. The refinery’s historical performance going back 5 years were evaluated as to their compliance to the relevant environmental standards. Environmental Risk Assessments were conducted for the additional tanks of benzene, gasoline and propylene as well as for the proposed power plant. The proposed power plant intends to use coal as its initial fuel and eventually shift to petcoke that is a byproduct of the coker unit that is being upgraded. Due to the number of ECCs that the refinery has had for its various expansion projects, these were integrated into a single ECC that was released in April 2010.
