Section 195.302 - General requirements(a) Except as otherwise provided in this section and in § 195.305(b) , no operator may operate a pipeline unless it has been pressure tested under this subpart without leakage. In addition, no operator may return to service a segment of pipeline that has been replaced, relocated, or otherwise changed until it has been pressure tested under this subpart without leakage.(b) Except for pipelines converted under § 195.5 , the following pipelines may be operated without pressure testing under this subpart: (1) Any hazardous liquid pipeline whose maximum operating pressure is established under § 195.406(a)(5) that is-(i) An interstate pipeline constructed before January 8, 1971;(ii) An interstate offshore gathering line constructed before August 1, 1977;(iii) An intrastate pipeline constructed before October 21, 1985; or(iv) A low-stress pipeline constructed before August 11, 1994 that transports HVL.(2) Any carbon dioxide pipeline constructed before July 12, 1991, that- (i) Has its maximum operating pressure established under § 195.406(a)(5) ; or(ii) Is located in a rural area as part of a production field distribution system.(3) Any low-stress pipeline constructed before August 11, 1994 that does not transport HVL.(4) Those portions of older hazardous liquid and carbon dioxide pipelines for which an operator has elected the risk-based alternative under § 195.303 and which are not required to be tested based on the risk-based criteria.(c) Except for pipelines that transport HVL onshore, low-stress pipelines, and pipelines covered under § 195.303 , the following compliance deadlines apply to pipelines under paragraphs (b)(1) and (b)(2)(i) of this section that have not been pressure tested under this subpart: (1) Before December 7, 1998, for each pipeline each operator shall-(i) Plan and schedule testing according to this paragraph; or(ii) Establish the pipeline's maximum operating pressure under § 195.406(a)(5) .(2) For pipelines scheduled for testing, each operator shall-(i) Before December 7, 2000, pressure test-(A) Each pipeline identified by name, symbol, or otherwise that existing records show contains more than 50 percent by mileage (length) of electric resistance welded pipe manufactured before 1970; and(B) At least 50 percent of the mileage (length) of all other pipelines; and(ii) Before December 7, 2003, pressure test the remainder of the pipeline mileage (length).Amdt. 195-51, 59 FR 29384, June 7, 1994, as amended by Amdt. 195-53, 59 FR 35471, July 12, 1994; Amdt. 195-51B, 61 FR 43027, Aug. 20, 1996; Amdt. 195-58, 62 FR 54592, Oct. 21, 1997; Amdt. 195-63, 63 FR 37506, July 13, 1998; Amdt. 195-65, 63 FR 59479, Nov. 4, 1998
