ENVIRONMENTAL PROTECTION AGENCY

[FRL-5932-8]


Use of Monitored Natural Attenuation at Superfund, RCRA 
Corrective Action, and Underground Storage Tank Sites; OSWER Directive 
9200.4-17; Interim Final

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: This 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. This Directive is being issued as Interim Final 
and may be used immediately. 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 document 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.
