                 Environmental Protection          (4305)                      December. 1999

        The U.S. Environmental Protection Agency (EPA) is fulfilling its obligation to report
     progress on developing guidance to facilitate water quality and designated use reviews for CSO
     receiving waters by submitting an outline of the draft guidance to the House Appropriations
     Committee, the House Transportation and Infrastructure Committee, the Senate Appropriations
     Committee'and the Senate'Environment and Public Works Committee.  Congress in House
     Report 105-769, accompanying EPA's FY 1999 Appropriations, urged the Agency to develop
     guidance and to provide technical and financial assistance to States and EPA Regions to conduct
     water quality standards reviews for CSO-receiving waters.

        The outline of the draft guidance, Implementation of the Water Quality-Based Provisions of
     the CSO Control Policy (EPA-823-R-99-015) provides information on the policy, programmatic
     and' technical guidance the Agency is developing for public review and comment in April, 2000.
     The draft guidance will lay a strong foundation for integrating the development and
     implementation of long-term combined sewer overflow (CSO) control plans with water quality
     standards reviews for CSO-receiving waters. By working closely together, CSO communities
     along with their community-based organizations,  States and EPA can achieve the level of CSO
     control in a combined sewer system to  contribute to the attainment of water quality standards.

         State water quality standards reviews for CSO receiving waters and revision of the standards
     or implementation procedures, if appropriate, require sound scientific data and analyses. The
     data collected and the analyses conducted by CSO communities as they develop their long-term
     CSO control plan can be used to inform States water quality standards reviews, if there is early
     agreement on the data and analyses that would be required to support any water quality standards
     revision Both the development and implementation of CSO  control plans and water quality
     standards reviews are iterative processes. These iterative processes enable implementation ot
     high priority CSO controls while data, information and analyses are developed to support water
     quality standards reviews.

          In addition to the outline of the draft guidance, EPA is providing two additional documents -
      Summary of Participant Comments at the EPA-WEFExperts Workshop on Implementing the
      WQ-Bald Provisions in the CSO Control Policy (EPA-823-R-99-016) and.Summaryof the
      Listening Sessions - Observations & Recommendations for Guidance and Technical Assistance
      to Facilitate Water Quality and Designated Use Reviews for Waters Impacted by Combined
      Sewer Overflows (EP A-8i3-R-99-017).  These documents provide the perspectives ot

mdiuduals with whom EPA consulted to identity impediments to implementing the water1
quality-based provisions of the CSO Control Policy and the actions the Agency should take to
overcome the impediments.
