Data Source and Calculation
DEQ provides the EPA with periodic summaries of Total Maximum Daily Load (TMDL) development progress. The schedule agreed upon by EPA for fully or partially removing waters from the Impaired Waters List is as follows: by FY 2014 (total 1,175); and by FY2020 (total 1,289). Water quality monitoring data is used to assess compliance with Water Quality Standards and compared to the baseline, measured on 6/30/2005.These data are based on the expectation that waters will be at least partially restored to meeting water quality standards within 10 years of completing a TMDL. The Chesapeake Bay and Virginia Waters Clean-Up Plan (most recent update January 2012), developed pursuant to HB 1150 (2006) recognizes both fully and partially restored waters.
