PTTGCA-Daelim U.S Petrochemcial Project’s Commitment to Protecting the Environment
PTTGCA-Daelim’s U.S. Petrochemical Complex is being designed and will be constructed and operated to be protective of human health and the environment in a socially responsible and environmentally sustainable manner. This is and will continue to be achieved by the following actions.
Protection of Land Natural Resources and Local History
- The cleanup and redevelopment of more than 400 acres of industrial land: Land use since the 1920s included a coal mine, sand and gravel quarry, asphalt batch plant and coal-fired power plant. Portions of the site were used for the storage and/or disposal of coal refuse material, coal bottom ash and fly ash and former underground petroleum strorage tanks.
- Protection of the biodiversity by avoiding impacts to threatened and/or endangered species.
- Protection and avoidance of sensitive archeological and cultural resources through the completion of cultural resource surveys and archaeological and geoarchaeological field surveys and investigations.
- Protection, preservation and improvement of Dilles Bottom Cemetery for the local community in memory of the first families that settled in Dilles Bottom: We will work with Mead Township to support the restoration and resetting of gravemarkers, construction of a protective decorative fence around the cemetery, and ongoing maintenance of the Cemetery.
Protection of Water Quality
- Increasing the net acreage of U.S. waters (i.e., wetlands and surface waters) of equivalent or better quality through the in-lieu fee mitigation program of the Stream and Wetlands Foundation.
- Improving the water quailty of Big Run Stream by reshaping, adding soil cover and revegetating the unreclaimed portions of the GOB piles facing Big Run Stream.
- Obtaining a wastewater discharge permit: The discharge limits and continuous monitoring requirements protect the Ohio River so it can continue to be used for drinking, recreation, other water supply needs and to support a healthy aquatic life.
- Providing Best Available Demonstrated Control Technology treatment levels that will produce effluent quality that will not degrade the Ohio River.
- Minimizing freshwater consumption by using closed-cycle cooling systems, recycling excess process water back to the cooling tower water basin, and using mist eliminators in the cooling towers to minimize water losses.
Protection of Air Quality
- Obtaining air permit: Air emissions from the plant will not prevent or interfere with the attainment or maintenance of National Ambient Air Quality Standards that were established by the U.S. and Ohio Environemntal Protection Agencies to protect human health and the environment. Emissions will be within the allowable Prevention of Significant Deterioration Class II area standards and will not cause adverse impacts on soil and vegetation or decrease visibility in the surrounding area.
- Providing Best Available Control Technology to minimize the amount of air emissions.
- Using natural gas and ultra Low-NOx burners to minimize the emissions from the steam boilers.
- Using recycled tail gas as the primary fuel source for the ethane cracking furnaces: The recycled tail gas is a byproduct of the ethane cracking furnaces.
- Using Low-NOx burners and Selective Catalytic Reduction to minimize the ethane cracking furnace NOx emissions.
- Using Thermal Oxidizers to destroy hydrocarbons from the ethane cracker unit and HDPE process vents, and vents from the hydrocarbon storage tanks, hydrocarbon liquid railcar loading and wastewater treament operations.
