Underground piping that conveys regulated substances under suction must: (i) Have a line tightness test conducted at least every three years and in accordance with section 11-280.1-44(2);(ii) Use a monthly monitoring method conducted in accordance with section 11-280.1-44(3); or(iii) Meet the standards in paragraph (6) (A) to (E).(2) Not later than ten years after the effective date of these rules, piping installed before August 9, 2013, for UST systems other than airport hydrant fuel distribution systems and UST systems with field-constructed tanks, must meet one of the following: (A) Pressurized piping. Underground piping that conveys regulated substances under pressure must: (i) Be monitored for releases at least every thirty-one days in accordance with section 11-280.1-43(7); and(ii) Be equipped with an automatic line leak detector in accordance with section 11-280.1-44(1).(B) Suction piping. Underground piping that conveys regulated substances under suction must: (i) Be monitored for releases at least every thirty-one days in accordance with section 11-280.1-43(7); or(ii) Meet the standards in paragraph (6)(A) to (E).(3) Piping installed on or after August 9, 2013, for UST systems other than airport hydrant fuel distribution systems and UST systems with field-constructed tanks, must meet the technical specifications in paragraph (2)(A) or (B).(4) Piping for UST systems with field-constructed tanks with a capacity less than or equal to 50,000 gallons and not part of an airport hydrant fuel distribution system: (A) Piping installed before the effective date of these rules must meet the technical specifications in paragraph (1) (A) or (B).(B) Not later than twenty years after the effective date of these rules, piping installed before the effective date of these rules must meet the technical specifications in paragraph (2)(A) or (B), unless an alternative design is approved by the director under section 11-280.1-21(c).(C) Piping installed on or after the effective date of these rules must meet the technical specifications in paragraph (2)(A) or (B).(5) Piping for airport hydrant fuel distribution systems and UST systems with field-constructed tanks with a capacity greater than 50,000 gallons must meet one of the following: (A) Pressurized piping.
