(6) Piping. As an exception to the double-walled piping requirement at 310 CMR 80.18(3)(a), Owners and Operators may use single walled piping when installing or replacing piping associated with airport hydrant systems. (7) Corrosion Protection. (a) In addition to the corrosion protection requirements in 310 CMR 80.22 and 80.29, Owners and Operators shall assess metal tanks greater than ten years old without cathodic protection to ensure the tank is structurally sound and free of corrosion holes prior to adding cathodic protection. The assessment shall be by internal inspection. (b) If the tank is not found to be structurally sound or free of corrosion holes, it shall be removed or closed in-place in accordance with 310 CMR 80.43. (8) Periodic Inspections. In addition to the periodic inspection requirements in 310 CMR 80.35, Owners and Operators shall inspect the following additional areas of airport hydrant systems at least once every 30 days if confined space entry according to the Occupational Safety and Health Administration (see 29 CFR part 1910) is not required or at least annually if confined space entry is required and keep documentation of the inspection according to 310 CMR 80.35(4). (a) Hydrant Fuel Pits – Visually check for any damage; remove any liquid or debris; manage the solid and liquid material removed from the tank in accordance with all applicable federal, state and local laws and regulations.; and check for any leaks; and (b) Hydrant Piping Vaults – Check for any hydrant piping leaks. (9) Leak Detection for Piping. (a) Methods of leak detection for underground piping associated with airport hydrant systems shall follow either the requirements in 310 CMR 80.19 and 80.26 or use one or a combination of the following alternative methods of leak detection: 1. Perform a semiannual or annual line tightness test at or above the piping operating pressure in accordance with the table below. Maximum Leak Detection Rate per Test Section Volume Test Section Volume (Gallons) Semiannual Test - Leak Detection Rate Not To Exceed (Gallons Per Hour) Annual Test - Leak Detection Rate Not To Exceed (Gallons Per Hour) < 50,000 1.0 0.5 ≥ 50,000 to < 75,000 1.5 0.75 ≥ 75,000 to < 100,000 2.0 1.0 ≥ 100,000 3.0 1.5 Piping segment volumes ≥ 100,000 gallons not capable of meeting the maximum 3.0 gallon per hour leak rate for the semiannual test may be tested at a leak rate of up to 6.0 gallons per hour according to the following schedule: Phase In For Piping Segments > 100,000 Gallons In Volume First test No later than October 13, 2022, may use up to 6.0 gph leak rate Second test Between October 14, 2022 and October 13, 2027, may use up to 6.0 gph leak rate Third test Between October 14, 2027 and October 13, 2028, shall use 3.0 gph for leak rate Subsequent tests After October 14, 2028, begin using semiannual or annual line testing according to the Maximum Leak Detection Rate Per Test Section Volume Table C above 2. Perform inventory control (conducted in accordance with Department of Defense Directive 4140.25; ATA Airport Fuel Facility Operations and Maintenance Guidance Manual; or equivalent procedures) at least every 30 days that can detect a leak equal to or less than 0.5% of flow-through and perform a line tightness test (conducted in accordance with 310 CMR 80.65(3)(b)1. using the leak rates for the semiannual test) at least every two years. (b) If a release or leakage is indicated by alarm other otherwise, the Owner or Operator shall immediately commence an investigation to determine whether there is a release or leakage. 1. The Owner or Operator shall conclude the investigation within 72 hours of the indication of release or leakage. 2. If the Owner or Operator is unable to determine that there is not a release or leakage, the Owner or Operator shall conduct a tightness test on the piping in accordance with 310 CMR 80.64(9)(a)1. 3. If the piping fails a tightness test pursuant to 310 CMR 80.32, the Owner or Operator shall comply with 310 CMR 40.0300: Notification of Releases and Threats of Release of Oil and Hazardous Materials; Identification and Listing of Oil and Hazardous Materials, as applicable. 4.
