Announcement of an extension of the public comment period due to revisions in the draft TMDL allocations for the Total Maximum Daily Load (TMDL) study to restore water quality in the tidal Potomac River, including selected tributaries to the tidal Potomac River in Maryland, Washington, D.C. and Virginia, that are impaired by the pollutant polychlorinated byphenyl (PCBs). The Potomac PCB Steering Committee discovered that certain aspects of the TMDL needed to be revised. These revisions include changes to the allocation loads for several stream segments. Due to these changes, the public comment period for this draft TMDL has been extended until close of business on August 23, 2007. A public meeting is not planned. However, if stakeholders review the revisions and feel that a meeting is necessary, a public meeting will be scheduled if a request is received by close of business on August 13, 2007. The revisions to the report can be found at: (http://www.potomacriver.org/water_quality/pcbtmdlpubmeet.htm
). DEQ accepts written comments by e-mail, fax, or postal mail. Written comments should include the name, address and telephone number of the person commenting, and be received by DEQ at the address provided below by August 23, 2007.
