More on EPA’s New Recommendations on Sediment Cleanups
Last month, we wrote about a new memorandum from the EPA’s Office of Land and Emergency Management that sets forth 11 recommendations for the agency’s regional offices on how to clean up contaminated sediments. Here we discuss some of those recommendations in greater detail. The EPA’s recommendations are shown below in bold text, followed by our comments and analysis. Recommendation 1: Consider early actions during the remedial investigation/feasibility study in site areas presenting high risks to help reduce risks quickly. Here, the EPA advises its regional offices not to wait until the sediments at a site are well characterized before taking steps to reduce serious risks. In many situations, the EPA can use its removal authority to reduce serious risks while other portions of the site are studied. Recommendation 2: Ensure adequate data collection during the remedial investigation/feasibility study to support the evaluation of alternatives. It’s never too early to plan ahead. From the very start of the process, the focus should be on collecting data that will support an eventual evaluation of remedial alternatives. Avoid “study for study’s sake.” Recommendation 3: Evaluate the risks associated with exposures to contaminated sediments, including submerged sediments. While the greatest risks at many sites likely involve ingestion of fish and shellfish, site managers should not ignore more direct pathways, such as...
