    Region 6 Fact Sheet
  • Annual Status Report
    This report was prepared by the Technology Innovation Office (TIO) to document the use of treatment technologies to remediate contaminated hazardous waste sites. The report contains a list and an analysis of Superfund sites (both remedial and removal actions), Resource Conservation and Recovery Act (RCRA) corrective action sites, and other non-Superfund sites (that is, sites addressed under other federal and state programs) where treatment technologies are being used.
• Policy Documents
  • OSWER Directive 9200.4-17P (April 21, 1999)
    "Use of Monitored Natural Attenuation at Superfund, RCRA Corrective Action, and Underground Storage Tank Sites." This version replaces the Interim Draft (December 1, 1997) and is distinguished from it by the "P" at the end of the Directive number. The Directive is 41 pages in length and consists of four parts: (1) cover sheet, (2) Directive Initiation Request (Form 1315-17), (3) transmittal memorandum--which contains a list of EPA Regional contacts (4 pages), and (4) directive text--which is 35 pages in length (counting the cover sheet, table of contents, and notice).
