4901:1-16-04. Records, maps, inspections, and leak classifications
-
(A) Each operator and gas gathering/processing plant pipeline operator shall establish and maintain all plans, records, reports, information, and maps necessary to ensure compliance with applicable sections of the pipeline safety code, and keep suchplans, records, reports, information, and maps in Ohio at the operator's head quarters or appropriate company office(s) readily available for inspection, examination, and copying by the commission, its staff, or its authorized representative(s).
(B) Each operator and gas gathering/processing plant pipeline operator shall provide and make available its plans, records, reports, information, and maps, as the commission, its staff, or its authorized representative(s) may require to administer and enforce the pipeline safety code.
(C) Each operator and gas gathering/processing plant pipeline operator shall permit the commission, its staff, and authorized representative(s) to: enter and inspect its premises, operations, and intrastate gas pipeline facilities; and inspect, examine, and copy its plans, records, reports, information, and maps, which the commission, its staff, or its authorized representative(s) may require to administer and enforce the pipeline safety code.
(D) Each operator and gas gathering/processing plant pipeline operator shall make its premises, operations, and intrastate gas pipeline facilities readily accessible to the commission, its staff, and its authorized representative(s).
(E) Except for an operator of a master meter system, each operator shall establish and maintain maps of the operator's service area which identify the operator's intrastate gas pipeline facilities, excluding service lines as defined in 49 C.F.R. 192.3 as effective on the date referenced in paragraph (D) of rule 4901:1-16-02 of the Administrative Code.
(F) Unless otherwise provided by this chapter, each operator and gas gathering/processing plant pipeline operator shall establish and retain records for three years to show compliance with the requirements of 49 C.F.R. 192 as effective on the date referenced in paragraph (D) of rule 4901:1-16-02 of the Administrative Code.
(G) Each operator shall retain records of each leak survey, as required by 49 C.F.R. 192.723 as effective on the date referenced in paragraph (D) of rule 4901:1-16-02 of the Administrative Code, for five years.
(H) Each operator shall classify all leaks utilizing leak detection equipment. As used in this rule, leak detection equipment means any device capable of detecting and measuring the concentration of natural gas in the atmosphere. The operator shall classify all hazardous leaks immediately and classify all other leaks within two business days of discovery. The operator shall classify leaks utilizing the following:
(1) A grade-one classification represents an indication of leakage presenting an existing or probable hazard to persons or property, and requires immediate repair or continuous action until the conditions are no longer hazardous.
(2) A grade-two classification represents an indication of leakage recognized as being nonhazardous at the time of detection, but requires scheduled repair based upon the severity and/or location of the leak.
(3) A grade-three classification represents an indication of leakage recognized as being nonhazardous at the time of detection and can be reasonably expected to remain nonhazardous.
(I) Upon discovery of the corresponding leak(s) from above, each opertor shall take the following actions:
(1) Take immediate and continuous action on leaks classified as grade one to protect life and property until the condition is no longer hazardous. Continuous action is defined as having personnel at the scene of the leak with leak detection equipment attempting to locate the source of the leak and taking action to prevent migration into structures, sewers, etc. If the hazardous condition associated with the leaks classified as grade one is eliminated, such as by venting, temporary repair, etc., but the possibility of the hazardous condition returning exists, the condition must be monitored as frequently as necessary, but at least once every eight hours, to protect life and property until the possibility of the hazardous condition returning no longer exists.
Leaks classified as grade one may be reclassified by performing a physical action to the pipeline (clamp, replacement, tape wrap, etc.) or pipeline facility. Reclassification must be in accordance with the criteria in paragraph (H) of this rule and by an individual who is qualified to classify leaks under the company's operator qualification plan. Venting, holes, aerators, or soil purging of a leak are not considered physical actions to the pipeline. If a leak is reclassified after performing a physical action, the timeframe for any required repair(s) and/or reevaluation(s) at the resulting classification will be calculated from the date the leak was reclassified. All grade one leaks repaired or reclassified, other than by the replacement of the affected section of pipe, must be reevaluated after allowing the soil to vent and stabilize but not more than 30 calendar days after such physical action.
(2) Repair or clear leaks classified as grade two no later than fifteen months from the date the leak is discovered, unless the pipeline containing the leak is replaced within twenty-four months from the date the leak is discovered. If a replacement project that will clear a leak classified as grade two is cancelled after the fifteenth month after classification of the leak(s), the associated leak(s) must be cleared within forty-five days of the cancellation of the project, not to exceed twenty-four months from the date of the leak classification. Leaks classified as grade two shall be reevaluated at least once every six months until cleared.
(3) Reevaluate leaks classified as grade three during the next scheduled survey or within fifteen months from the date of the last inspection, whichever is sooner, and continue to reevaluate such leaks on that same frequency until there is no longer any indication of leakage, the leak is reclassified, or the pipeline is replaced.
