Change to Bacteria Total Maximum - Pamunkey River

Posted on 06/28/2008

NOTICE OF PUBLIC COMMENT BACTERIA TOTAL MAXIMUM DAILY LOAD FOR THE PAMUNKEY RIVER BASIN ISSUED: JUNE 23, 2008 COMMENT PERIOD ENDS: JULY 23, 2008 Notice is hereby given that the State Water Control Board seeks comment on the proposed modifications to the bacteria Total Maximum Daily Load (TMDL) developed for the Pamunkey River Basin in Louisa, Caroline, Hanover, Orange, King William, and New Kent Counties. The total maximum daily load of E. coli was developed to address bacterial impairment in the Pamunkey River Basin. The TMDL was approved by the Environmental Protection Agency (EPA) on 8/2/06 and can be found at the following websites: www.deq.virginia.gov/tmdl www.epa.gov/reg3wapd/tmdl/VA_TMDLs/PamunkeyRiverBac/PamunkeyRvBac_DR.pdf The Virginia Department of Environmental Quality (VDEQ) seeks written comments from interested persons on the modification of this TMDL. In the Pamunkey River Basin bacterial TMDL approved by the U.S. Environmental Protection Agency and the State Water Control Board in 2006, the Missionary Learning Center Sewage Treatment Plant (STP) , VA0067105, was issued a waste load allocation of 4.4E+10 cfu/year, based on the design flow (25,000 gallons per day or gpd) at the time of issuance. DEQ proposes to revise the TMDL by increasing the bacteria waste load allocation to 1.17E+11 cfu/year to accommodate this facility at a maximum design flow of 65,000 gpd and an E. coli concentration of 126 N/100mL. This increase will neither cause nor contribute to the non-attainment of the Pamunkey River Basin, as documented in the EPA approved TMDL report. The EPA considers a less than 1% change to the TMDL to be insignificant. The proposed increase in the waste load allocation for this facility will be 0.37% of the TMDL. The public comment period for this modification will end on July 23, 2008. Questions or information requests should be addressed to Margaret Smigo. Written comments should include the name, address, and telephone number of the person submitting the comments and should be sent to Margaret Smigo, Piedmont Regional Office, Department of Environmental Quality, 4949-A Cox Road, Glen Allen, VA 23060, telephone (804) 527-5124, or email mjsmigo@deq.virginia.gov.
