## Abstract

The Environmental Protection Agency ("EPA," "the Agency" or "we" in this preamble) today is granting a petition submitted by the ConocoPhillips Billings, Montana Refinery ("ConocoPhillips", "Refinery" or "Petitioner") to exclude or "delist," from the list of hazardous wastes, a maximum of 200 cubic yards per year of residual solids from sludge removed from two storm water tanks at its Billings, Montana refinery and processed in accordance with the petition. After careful analysis we have concluded that the petitioned waste is not a hazardous waste. This exclusion conditionally excludes the petitioned waste from the requirements of hazardous waste regulations under the Resource Conservation and Recovery Act (RCRA) when processed in accordance with the petition and disposed in a Subtitle D landfill permitted, licensed, or otherwise authorized by a State to accept the delisted processed storm water tank sludge. This rule also imposes testing conditions for future processed storm water tank residuals to ensure they continue to qualify for delisting.
