Dec. 3 -- EPA clarifies policy on natural attenuation

 U.S. EPA posted on the World Wide Web a clarification of its policy
regarding the use of monitored natural attenuation for the remediation of
contaminated soil and groundwater at sites regulated under the agency's Office 
of Solid Waste and Emergency Response. Remediation projects covered by 
the directive include those conducted under EPA's Superfund, corrective 
action and underground storage tank programs. Although the directive does 
not contain technical guidance or new regulations, it should be used 
beginning immediately to guide development of proposals, evaluations and 
agency approvals of natural attenuation remedies, EPA said. The directive 
may be downloaded in a variety of formats on
the World Wide Web at http://www.epa.gov/OUST/directiv/d9200417.htm .
