DEC recently adopted revisions to the Oil and Other Hazardous Substances Pollution Control regulations in 18 AAC 75. These regulations serve as the basis for decisions which are made to prevent and clean up spills and contaminated properties in Alaska. The changes took effect October 9th, 2008.

Tables of cleanup levels have been updated to reflect new toxicity information, and a number of chemicals found or suspected at Alaska contaminated sites have been added. Other substantive modifications include repeal of the groundwater "10-times rule" and technical updates to the department's Cleanup Levels Guidance and Cumulative Risk Guidance documents.

If you are a consultant currently working on a cleanup project, please contact your assigned DEC project manager regarding implementation of the revised cleanup levels.
