  • Water Quality Trading Assessment Handbook - EPA is releasing a document to help water quality managers and watershed stakeholders determine if trading can be used in their watershed to make cost-effective pollutant reductions that achieve water quality standards. Using a hypothetical river basin, the The Water Quality Trading Assessment Handbookillustrates an analytical framework that can be used in any watershed to evaluate the conditions and water quality problem(s) and determine if water quality trading might effectively address local conditions. You can order paper copies of the handbook free of charge through the National Service Center for Environmental Publications at (800)490-9198 or via email at ncepimal@one.net You can find additional information about water quality trading at www.epa.gov/owow/watershed/trading.htm For handbook questions you may contact Lynda Hall (202)566-1210 or Katharine Dowell (202)564-1515 (Office of Water).

  • Air Quality Criteria for Particulate Matter (October 2004) - EPA has completed the process of updating and revising, where appropriate, its Air Quality Criteria for Particulate Matter (PM) as issued in 1996 (usually referred to as the Criteria Document). Sections 108 and 109 of the Clean Air Act require that EPA carry out a periodic review and revision, where appropriate, of the air quality criteria (embodied in the Criteria Document) and national ambient air quality standards (NAAQS) for criteria air pollutants such as PM. The final version of the entire PM Criteria Document was issued in October 2004 (National Center for Environmental Assessment).

  • Standardized Analytical Methods for Use During Homeland Security Events - EPA's Homeland Security Research Center, in conjunction with EPA's Laboratory and Capability Committee, has developed a list of Standardized Analytical Methods (SAM) to be used by environmental laboratories in analyzing biological and chemical samples associated with threats to homeland security. SAM provides a standard by which to measure specific types of contamination that may be associated with future terrorist attacks. Ultimately, these procedures will be vitally important in assisting state and local government laboratories that are preparing to analyze samples associated with homeland security events. A 90 pp., 580 KB Adobe Acrobat (PDF) document from the Office of Ground Water and Drinking Water.
