(192.8)\n\nA. An operator must use API RP 80 (incorporated by reference in 49 CFR 192.7 and adopted in (1)(D)), to determine if a pipeline (or part of a connected series of pipelines) is a gathering line. The determination is subject to the limitations listed below. After making this determination, an operator must determine if the gathering line is a regulated gathering line under paragraph (1)(E)1.\n\n(I) The beginning of gathering, under section 2.2(a)\n\n(1) of API RP 80, may not extend beyond the furthermost downstream point in a production operation as defined in section 2.3 of API RP 80. This furthermost downstream point does not include equipment that can be used in either production or transportation, such as separators or dehydrators, unless that equipment is involved in the processes of ''production and preparation for transportation or delivery of hydrocarbon gas'' within the meaning of ''production operation.''\n\n(II) The endpoint of gathering, under section 2.2(a)(1)(A) of API RP 80, may not extend beyond the first downstream natural gas processing plant, unless the operator can demonstrate, using sound engineering principles, that gathering extends to a further downstream plant.\n\n(III) If the endpoint of gathering, under section 2.2(a) (1)(C) of API RP 80, is determined by the commingling of gas from separate production fields, the fields may not be more than fifty (50) miles from each other, unless the administrator finds a longer separation distance is justified in a particular case (see 49 CFR 190.9).\n\n(IV) The endpoint of gathering, under section 2.2(a) (1)(D) of API RP 80, may not extend beyond the furthermost downstream compressor used to increase gathering line pressure for delivery to another pipeline.\n\n(V) For new, replaced, relocated, or otherwise changed gas gathering pipelines installed after May 16, 2022, the endpoint of gathering under sections 2.2(a)(1)(E) and 2.2.1.2.6 of API RP 80-also known as ''incidental gathering''-may not be used if the pipeline terminates ten (10) or more miles downstream from the furthermost downstream endpoint as defined in paragraphs 2.2(a)(1)(A) through (a)(1)(D) of API RP 80 and this paragraph. If an ''incidental gathering'' pipeline is ten (10) miles or more in length, the entire portion of the pipeline that is designated as an incidental gathering line under 2.2(a)(1)(E) and 2.2.1.2.6 of API RP 80 shall be classified as a transmission pipeline subject to rules 20 CSR 4240-40.020, 20 CSR 4240-40.030, 20 CSR 4240-40.033, and 20 CSR 4240-40.080.\n\nB. Each operator must determine and maintain for the life of the pipeline records documenting the methodology by which it calculated the beginning and end points of each gathering pipeline it operates, as described in the second column of table 1 to part (1)(E)1.C.(II), by-\n\n(I) November 16, 2022, or before the pipeline is placed into operation, whichever is later; or\n\n(II) An alternative deadline approved by the Pipeline and Hazardous Materials Safety Administration (PHMSA). The operator must notify PHMSA and designated commission personnel no later than ninety (90) days in advance of the deadline in part (1)(E)1.B.(I). The notification must be made in accordance with subsection (1)(M) and must include the following information: (a) Description of the affected facilities and operat- ing environment; (b) Justification for an alternative compliance dead- line; and (c) Proposed alternative deadline.\n\nC. For purposes of 20 CSR 4240-40.020 and paragraph (1) (E)2., the term ''regulated gathering pipeline'' means-\n\n(I) Each Type A, Type B, or Type C gathering pipeline (or segment of gathering pipeline) with a feature described in the second column of table 1 to part (1)(E)1.C.(II) that lies in an area described in the third column; and\n\n(II) As applicable, additional lengths of pipeline de- scribed in the fourth column to provide a safety buffer. Table 1 to Part (1)(E)1.C.(II) C • Type Feature Area Safety Buffer A • • • Metallic and the MAOP produces a hoop stress of twenty percent (20%) or more of SMYS. If the stress level is unknown, an operator must determine the stress level according to the applicable provisions in section (3). Non-metallic and the MAOP is more than one hundred twenty-five\n\n(125) psig (862 kPa). Class 2, 3, or 4 location (see subsection (1)(C)). None. B • Outside diameter greater than or equal to 8.625 inches and any of the following: -Metallic and the MAOP produces a hoop stress of twenty percent (20%) or more of SMYS; -If the stress level is unknown, segment is metallic and the MAOP is more than one hundred twenty-five\n\n(125) psig (862 kPa); or -Non-metallic and the MAOP is more than one hundred twenty- five\n\n(125) psig (862 kPa). Class 1 location. None. • Metallic and the MAOP produces a hoop stress of less than twenty percent (20%) of SMYS. If the stress level is unknown, an operator must determine the stress level according to the applicable provisions in section (3). Non-metallic and the MAOP is one hundred twenty-five\n\n(125) psig (862 kPa) or less. Area 1. Class 3 or 4 location. Area 2. An area within a Class 2 location the operator determines by using any of the following three (3) methods: (a) A Class 2 location; (b) An area extending one hundred fifty feet (150') (45.7 m) on each side of the centerline of any continuous one\n\n(1) mile (1.6 km) of pipeline and including more than ten (10) but fewer than forty- six (46) dwellings; or (c) An area extending one hundred fifty feet (150') (45.7 m) on each side of the centerline of any continuous one thousand feet (1000') (305 m) of pipeline and including five (5) or more dwellings. If the gathering pipeline is in Area 2(b) or 2(c), the additional lengths of line extend upstream and downstream from the area to a point where the line is at least one hundred fifty feet (150') (45.7 m) from the nearest dwelling in the area. However, if a cluster of dwellings in Area 2(b) or 2(c) qualifies a pipeline as Type B, the Type B classification ends one hundred fifty feet (150') (45.7 m) from the nearest dwelling in the cluster. R All other gathering lines. Class 1 and Class 2 locations. None.\n\n(III) A Type R gathering line is subject to reporting requirements under 20 CSR 4240-40.020 but is not a regulated gathering line under this rule.\n\n(IV) For the purpose of identifying Type C lines in table 1 to part (1)(E)1.C.(II), if an operator has not calculated MAOP consistent with the methods at paragraph (12)(M)1. or subparagraph (12)(M)3.A., the operator must either- (a) Calculate MAOP consistent with the methods at paragraph (12)(M)1. or subparagraph (12)(M)3.A.; or (b) Use as a substitute for MAOP the highest operat- ing pressure to which the segment was subjected during the preceding five (5) operating years.\n\n2.
