- (A) Spill prevention equipment. Visually check for damage, remove liquid or debris, check for and remove obstructions in the fill pipe, check the fill cap to ensure it is securely on the fill pipe; and for double-wall spill prevention equipment with interstitial monitoring, check for a leak in the interstitial area; and
- (B) Release detection equipment. Check to ensure the release detection equipment is operating with no alarms or other unusual operating conditions present, and ensure records of release detection testing are reviewed and current; or
- (ii) Conduct operation and maintenance walkthrough inspections according to PEI RP900, as referenced in Section 2.
- (iii) Owners and/or operators who monitor their release detection system remotely may check the release detection equipment and records remotely every 30 days as long as the release detection system at the facility is determined to be in communication with the remote monitoring equipment.
(e) Monthly Inspection Documentation. The Class A or B Operator or licensed tank tester shall provide the facility owner and/or operator with a copy of each monthly inspection documentation and alert the owner and/or operator of any condition discovered during the monthly visual inspection that may require follow-up actions.
(f) Monthly Inspection Records. The owner and/or operator shall maintain a copy of the monthly inspection documentation and all attachments for the previous 12 months. Records shall include a list of each area checked, whether or not each area checked was acceptable or needed action taken, a description of actions taken to correct an issue, and delivery records if spill prevention equipment is checked less frequently than every 30 days due to infrequent deliveries. The records shall be maintained on-site, off-site at a readily available location within the State of Wyoming, or electronically in accordance with Section 13(i).
(g) Operator's Annual Inspection. Storage tank system owners and/or operators shall provide an annual inspection report to the department for the entire facility within 60 days of the inspection. This annual inspection shall be conducted by the owner, the operator, or a licensed tester within 1 year of the previous inspection. The inspector shall meet all qualifications of a CP tester if he or she inspects a CP system. The results of the operator's annual inspection and all associated documentation shall be maintained by the facility for at least 3 years. Records shall include a list of each area checked and each component tested, whether each area checked and each component tested was acceptable or needed action taken, a description of actions taken to correct an issue, and delivery records if spill prevention equipment is checked less frequently than every 30 days due to infrequent deliveries. This inspection shall: - (i) Test all CP systems on site that are due for testing in accordance with Section 11.
- (ii) Provide pressure tests of pressurized piping or U.S. suction piping in accordance with Section 14(g).
- (iii) Test all automatic line leak detectors as follows:
- (A) Provide a simulated leak test for mechanical line leak detectors that demonstrates the leak detector meets the requirements of Section 14(g).
- (B) Provide a simulated leak test for electronic line leak detectors that demonstrates the leak detector meets the requirements of Section 14(g). An internal electrical test of the system is not sufficient to meet this requirement.
- (C) The annual inspection shall include a manual tripping of each sump sensor. A record shall be made showing the date when the test was done, the facility number, and recording whether or not the sensor operated as required. The sensor shall be placed in accordance with Section 14(h)(v).
