(a) Applicability: The standards in this section apply to all solid waste management facilities which manage petroleum storage tanks, unless one of the following conditions are met: - (i) The provisions of this section do not apply to the temporary storage of petroleum storage tanks at the point of generation if the following standards are met:
- (A) The time of the waste management activity does not exceed thirty (30) days;
- (B) Public access to the solid waste management unit is controlled;
- (C) The petroleum storage tanks are identified by Department of Transportation (DOT) placards which identify the original contents on the tanks;
- (D) Measures are taken to insure that the atmospheres in the petroleum storage tanks are maintained at levels less than twenty-five (25) percent of the lower explosive limit.
- (ii) Upon request by a solid waste management facility operator, the administrator may waive application of the provisions of this section where the administrator finds that the petroleum storage tanks are of a limited volume, the management event is likely to be a nonrecurring event, and the operator demonstrates that the management can occur in a manner that is protective of the public health and safety;
- (iii) The provisions of this section may be waived by the administrator if the petroleum storage tank owner can demonstrate that the petroleum storage tank contains de minimis quantities of petroleum products, sludges and scale, and has an ambient atmosphere which is less than ten (10) percent of the lower explosive limit (LEL);
(b) Location standards: All facilities which transfer, treat and store petroleum storage tanks shall belocated in accordance with the following standards, as well as any other applicable facility location standards; - (i) Facilities shall not be located within 100 feet of any occupied dwelling house, school or hospital except with the written consent of the owner or school district board of trustees, as applicable;

- (iii) Facilities shall not be located in an area which is not approved by the governing fire marshall;
- (iv) The administrator may authorize any existing solid waste management facility which does not conform with the location requirements of this subsection to manage petroleum storage tanks, provided the operator demonstrates that the facility design and construction, operating procedures, monitoring procedures and closure procedures are protective of human health and the environment.
(c) Design & construction standards: All facilities which transfer, treat and store petroleum storage tanks shall be designed and constructed in accordance with the following standards, as well as any other applicable facility design and construction standards: - (i) Solid waste management units shall be constructed in an area of the facility which is physically isolated from other areas of the facility which are frequented by the general public;
- (ii) Solid waste management units shall be designed and constructed to prevent the migration of contaminants to soils, ground water and surface water.
(d) Operating standards: All facilities which transfer, treat and store petroleum storage tanks shall be operated in accordance with the following standards, as well as any other applicable facility operating standards: - (i) Petroleum storage tanks shall be managed in conformance with American Petroleum Institute Publications 1604, 1631, 2015 and/or other relevant publications as recommended by Subtitle I of the Resource Conservation and Recovery Act as amended as of September 23, 1988, unless equivalent procedures are approved by the administrator;
- (ii) Petroleum storage tanks shall be managed within forty-eight (48) hours unless measures are taken to insure that atmospheres in the petroleum storage tanks areless than twenty-five (25) percent of the lower explosive limit;
- (iii) Petroleum storage tanks shall be managed to meet the following objectives:
- (A) Residual petroleum products shall be removed;
- (B) Residual sludge and scale shall be removed;
- (C) Ambient tank atmospheres shall be less than ten percent (10%) of the lower explosive limit and contain a minimum of nineteen and one-half (19.5) percent by volume oxygen.
- (iv) All wastes generated by the petroleum storage tank management process shall be collected, containerized and properly managed in compliance with applicable local, state and federal requirements;
- (v) Any spill(s) or leak(s) of refined product which is greater than twenty-five (25) gallons shall be reported to the Water Quality Division within forty-eight (48) hours following the spill(s) or leak(s). The operator shall submit to the Solid and Hazardous Waste Division a written remedial plan describing the steps taken to abate the problem within seven (7) days after the spill or leak;
- (vi) The operator shall provide the waste generator with written certification at the completion of the petroleum storage tank management process. Written certification shall contain, at a minimum, the following information:
- (A) The name and address of the generator of the petroleum storage tanks;
- (B) The location at which the petroleum storage tanks were generated, including the Wyoming Department of Environmental Quality/Water Quality Division registration numbers, if applicable;
- (C) The dimensions and capacity of the petroleum storage tanks;
- (D) The volume and disposition of any wastes generated by the petroleum storage tank management process; and
- (E) The date on which management of the petroleum storage tanks was completed.
- (vii) The following records shall be marked with the appropriate date and time and maintained at the facility or an approved alternative location and available for inspection and copying as specified by Chapter 1, Section 1(g):
- (A) Copies of any analytical testing done to characterize any wastes generated by the petroleum storage tank management process;
- (B) Copies of all written certifications which are issued to generators.
