ENVIRONMENTAL RELEASES ESTIMATE SUMMARY IRER Note: The daily releases listed for any source below may coincide with daily releases from the other sources to the same medium. Note: Based on information from past case P14

- 0089c: no releases are expected from "Cleaning Liquid Residuals from Tank Tr ucks Used to Transport the Raw Material". Standard industry practices do not undertake tank truck cleaning operations; this is substantiated with support letters from trucking companies. EPA also did not assess equipment cleaning releases because the subm ission states that once the PMN is incorporated into the asphalt emulsion, the PMN substance is becomes a part of the asphalt itself.
