The LDEQ, Office of Environmental Services, is accepting written comments on a draft Louisiana Pollutant Discharge Elimination System (LPDES) permit prepared for Westlake Chemical Corporation, Westlake Petrochemicals Complex, P.O. Box 3508, Sulphur, LA 70664. The facility is located at 900 Louisiana Highway 108 in Sulphur, Calcasieu Parish. Upon the effective date of the final permit, the LPDES permit shall replace the previously issued LPDES permit.
The principal discharge from this existing source is made into the Calcasieu River (Outfall 001) and Indian Marais (Outall 006), waters of the state classified for primary contact recreation, secondary contact recreation, and propagation of fish and wildlife. Under the SIC Codes 2869, 2821, and 2865, the applicant proposes to discharge combined wastewaters from the Styrene, Poly III, and Petro I & II Units including: treated process wastewaters; utility wastewaters; process area stormwater; treated sanitary wastewater from Internal Outfalls 101, 401, and 501; and miscellaneous wastewater including but not limited to general facility washdown, steam condensate, eye wash and safety shower station water, firewater, and pump seal water (Outfall 001) and non-process area stormwater runoff from throughout the Westlake Petrochemicals Complex including the secondary containment area around the hexane and butane tanks near the Co-Products Storage area; utility fire test water overflow; firewater pump cooling and test water; excess clarifier/utility water, demineralization unit overflow; excess post-first flush stormwater runoff from the process areas at the Petro II and Poly III Units; steam condensate; lay down yard; contractor areas; and other miscellaneous non-contact wastewater and wash waters (Outfall 006) from an existing chemical complex for styrene, ethylene, and polyethylene production.
During the preparation of this permit, it has been determined that the discharge will have no adverse impact on the existing uses of the receiving waterbody. As with any discharge, however, some change in existing water quality may occur.
