Section 170.590  Reporting and Cleanup of Spills and Overfills

a)         Owners or operators of UST systems shall contain and immediately clean up a spill or overfill and report either release to Illinois Emergency Management Agency within 24 hours (if the product released is a hazardous substance, see Section 170.600 of this Part), and begin initial response and initial abatement in accordance with Sections 170.600 and 170.610, in the following cases:

1)         Spill or overfill of petroleum that results in a release to the environment that exceeds 25 gallons or that causes a sheen on nearby surface water; or

2)         Spill or overfill of a hazardous substance that results in a release to the environment that equals or exceeds its reportable quantity under 40 CFR 302.1 and 302.5, incorporated by reference in Section 170.410.

b)         Owners or operators of UST systems shall contain and immediately clean up a spill or overfill of petroleum that is 25 gallons or less and a spill or overfill of a hazardous substance that is less than the reportable quantity. In doing so, procedures specified in Section 170.610 (a) through (d) shall be complied with.  If cleanup cannot be accomplished within 24 hours, owners or operators shall immediately notify Illinois Emergency Management Agency (IEMA).  (Under 40 CFR 302.1, incorporated by reference in Section 170.410, a release of a hazardous substance equal to or in excess of its reportable quantity shall also be reported immediately (rather than within 24 hours) to the National Response Center (800/424-8800).)  In addition, 35 Ill. Adm. Code 750.410 requires notification of IEMA (800/782-7860).
