020-1 Wyo. Code R. § 1-22
(a) Cleanup and 24-Hour Reporting. Owners and/or operators of storage tank systems shall contain and immediately clean up a spill or overfill. Spills and overfills shall be reported to the department within 24 hours by telephone (307) 777-7097 (STP) and (307) 777-7781 (spill response) and by logging into the spill response database on the DEQ website. The owner and/or operator shall begin corrective action in accordance with Sections 23 through 25 in the following cases:
(b) Owner's and/or Operator's Costs. Costs incurred by owners and/or operators to contain and/or cleanup surface spills and/or overfills are not eligible for the state Corrective Action Account funds. Releases that occur within a dispenser cabinet at or above the fire valve are considered surface spills and are not eligible for cleanup under the Corrective Action Account. Releases that occur below the fire valve are considered releases from piping and are eligible for cleanup under the Corrective Action Account.
(c) Small Spills. Owners and/or operators of storage tank systems shall contain and immediately cleanup a spill or overfill of petroleum that is less than 25 gallons and a spill or overfill of a hazardous substance that is less than the reportable quantity. If cleanup cannot be accomplished within 24 hours, owners and/or operators shall immediately notify the department.
(d) Other Reporting. A release of a hazardous substance equal to or in excess of its reportable quantity must also be reported immediately (rather than within 24 hours) to the National Response Center in accordance with CERCLA (1980) and to appropriate state and local authorities under Title III of the Superfund Amendments and Reauthorization Act of 1986.
