    The Center for Watershed Protection (CWP) and Dr. Robert Pitt (Univ. of Alabama) recently completed the Illicit Discharge Detection and Elimination (IDDE) Guidance Manual, prepared under an EPA cooperative agreement. The final guidance has just been posted on two web sites - www.cwp.org(scroll down on right hand side) and www.stormwatercenter.net(on left menu select program resources and illicit discharges) and is free to download. This guidance is particularly useful for Phase II NPDES MS4 communities and others seeking to establish IDDE programs and investigate non-storm water entries into storm drainage systems. The manual also has application for Phase I communities looking to modify existing programs, and for groups interested in conducting public outreach and awareness activities as part of watershed restoration projects.

    On December 6, 2005, EPA released the National Management Measures to Control Nonpoint Source Pollution from Urban Areas. This comprehensive document will help local governments and others protect water resources from polluted runoff that can result from everyday activities and urban development. The guidance will also help municipalities and other regulated entities implement their Phase I and Phase II NPDES Stormwater programs. This publication includes voluntary guidance on 12 management measures designed to prevent and control runoff pollutants from urban and suburban lands. The management measures cover topics such as watershed assessment and protection runoff from new and existing development, road networks, and construction sites septic system impacts pollution prevention and inspection and maintenance of urban runoff management practices. This new guidance document is available at www.epa.gov/owow/nps/urbanmm.
