[Federal Register: May 10, 1999 (Volume 64, Number 89)] [Notices] [Page 25039-25040] From the Federal Register Online via GPO Access [wais.access.gpo.gov] [DOCID:fr10my99-69] ----------------------------------------------------------------------- ENVIRONMENTAL PROTECTION AGENCY [FRL-6338-8] Use of Monitored Natural Attenuation at Superfund, RCRA Corrective Action, and Underground Storage Tank Sites; OSWER Directive 9200.4-17P; Final AGENCY: Environmental Protection Agency (EPA). ACTION: Notice of availability. ----------------------------------------------------------------------- SUMMARY: This Directive replaces the Interim Draft that was released December 1, 1997. The Directive clarifies the U.S. Environmental Protection Agency's (EPA) policy regarding the use of Monitored Natural Attenuation for the remediation of contaminated soil and groundwater at sites regulated under Office of Solid Waste and Emergency Response (OSWER) programs. These include programs administered under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or ``Superfund''), the Resource Conservation and Recovery Act (RCRA), the Office of Underground Storage Tanks (OUST), and the Federal Facilities Restoration and Reuse Office (FFRRO). The Directive is intended to promote consistency in how monitored natural attenuation remedies are proposed, evaluated, and approved. As a policy document, it does not provide technical guidance on evaluating Monitored Natural Attenuation remedies. It provides guidance to EPA staff, to the public, and to the regulated community on how EPA intends to exercise its discretion in implementing national policy on the use of Monitored Natural Attenuation. The Directive does not, however, substitute for EPA's statutes or regulations, nor is it a regulation itself and, thus, it does not impose legally-binding requirements on EPA, States, or the regulated community, and may not apply to a particular situation based upon the circumstances. EPA may change this guidance in the future, as appropriate. ADDRESSES: Electronic Access.
