Union Carbide - Seadrift Plant

Year Submitted: 2003

Process: Wastewater Treatment

Industry: Chemical Manufacturing

Wastes Reduced: VOC Emissions

Equipment: Liner

Location: Port Lavaca TX

No. of employees: 1150

Contact: Rick Curtis

Phone: (512) 553-2435


Union Carbide's Seadrift Plant has completed an extensive project to improve our wastewater treatment system. Two earthen water treatment lagoons have been replaced with modern fully enclosed, 5.5 acre wastewater treatment reactor. The new system will improve the biodegradation of organics and will essentially eliminate organic off-gas emissions normally associated with treatment systems.

P2 Application:

The replacement lagoon itself is designed and constructed in accordance with federal surface impoundment guidelines. While not mandatory, the system has a 5.5 acre 100 ml floating HDPE cover over the entire area to contain odors that would be generated.

Environmental Benefits:

This project benefits the environment as a result of the protection which it provides for the earth and groundwater, as well as the air and water. A total reduction of 800 tons/year of hydrogen sulfide and 12.5 tons/year of VOC's to the air has been achieved.

Details of Reductions

Additional Information :

In addition to the environmental benefit, the odors from the treatment system are dramatically reduced, which also benefits employees and near-neighbors.
