The Celanese Wastewater Treatment Plant is the first facility to be completely upgraded to enhanced nutrient removal (ENR) under the Chesapeake Bay Restoration Fund (BRF). The $15.8 million Celanese Wastewater Treatment Plant, originally constructed in the 1960’s, will dramatically reduce the level of nitrogen and phosphorus being discharged directly to the Potomac River a tributary to the Chesapeake Bay.
This enhanced nutrient removal upgrade is capable of achieving an effluent with a Total Nitrogen goal of 3 milligrams per liter (mg/l) and Total Phosphorus of 0.3mg/l. Upon completion of all 66 major wastewater treatment plants, upgraded with the use of the landmark Bay Restoration Funds, an impact to the bay will be a 7.5 million pound annual reduction in nitrogen and a 260,000 pound annual reduction in phosphorus.
The Maryland Department of the Environment’s (MDE) wastewater treatment plant improvement program is the centerpiece of the Ehrlich-Steele Administration's holistic approach to bay restoration which includes nutrient reduction, bay grasses and oyster restoration. At this time, 10 other wastewater facilities are under design to be upgraded and 29 other wastewater facilities have initiated the planning phase to be upgraded to enhanced nutrient removal.
By 2007, construction will be underway at nearly half the major wastewater plants in the state. The Chesapeake Bay is Maryland’s greatest economic and environmental treasure and the citizens of Maryland have an obligation to preserve and protect the bay for future generations.
