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.
