Effective January 1st, 2008, EHS will no longer require monthly sewer logs to be submitted online. Please continue to maintain sewer logs posted at the approved disposal sink. RUDs (Receipt for Use & Disposal forms) will be used to report sewer disposal activities to EHS, and to have material removed from your inventory limits. Please ensure all RUDs are properly filled out, and returned to EHS promptly, when the source material has been completely accounted for.
