| Abstract |
Section 303(d) of the Federal Clean Water Act requires each state to identify waters not attaining water quality standards, and to establish total maximum daily loads (TMDLs) for such waters for the pollutant of concern. The TMDL establishes the allowable pollutant loading from all contributing sources at a level necessary to attain the applicable water quality standards. TMDLs must account for seasonal variability and include a margin of safety that accounts for uncertainty of how pollutant loadings may impact the receiving water's quality. Once the public has had an opportunity to review and comment on the TMDL, it is submitted to the U.S. Environmental Protection Agency (USEPA) for approval. Upon approval, the TMDL is incorporated into the state's water quality management plan. This TMDL establishes a scientifically based water quality target for Potash Brook that, when attained, will allow the stream to meet or exceed the established Vermont Water Quality Standards (VTWQS) for which it is impaired. This TMDL has been established in accordance with Section 303(d) of the Federal Clean Water Act, implementing regulations (40 CFR Section 130) regarding TMDL development, and other relevant USEPA guidance documents. The basis for this TMDL was initially explained in the final report produced by the Vermont Water Resources Board Investigative Docket (Vermont Water Resources Board, 2004). More specifically, Appendix A of that document ('A Scientifically Based Assessment and Adaptive Management Approach to Stormwater Management)(Stormwater Cleanup Plan Framework') outlined the necessary steps to develop a scientifically sound approach in creating TMDLs for stormwater-impaired waters. Henceforth, this approach is referred to as the 'Framework'. The Vermont Department of Environmental Conservation (VTDEC) adhered to the Framework's approach for developing cleanup targets in this TMDL. |
