Evergreen Park Drive\nP.O. Box 47250\nOlympia, WA 98504-7250\nDear Mr. Curl:\nWe have considered your letter of December 30, 1992, notifying us the Washington Utilities and\nTransportation Commission (WUTC) waived the definition of \"main\" in 49 CFR 192.3 for the\nWashington Natural Gas Company. The waiver permits no more than two adjoining residential-\nbuilding customers to be supplied gas from a common pipeline without classifying that pipeline as\na \"main.\"\nWe have no objection to the waiver from a safety standpoint. The circumstance are comparable\nto those of previous waivers we approved that were granted in 1989 and 1990 by the Arizona\nCorporation Commission and the Public Service Commission of Nevada.\nAs you know, WUTC did not have a certification or agreement in effect under Section 5 of the\nNatural Gas Pipeline Safety Act of 1968, as amended (NGPSA), when the waiver was granted.\nBecause the authority of state agencies to waive a safety standard established under the NGPSA\ndepends on the existence of such certifications or agreements (49 App. U.S.C. 1674), we are\nconcerned about the legitimacy of the waiver. We believe this problem would be corrected if\nWUTC would reissue the waiver to the Washington Natural Gas Company. WUTC need not\nresubmit the waiver to us for further consideration after it is reissued.\nSincerely,\nGeorge W. Tenley, Jr.\nAssociate Administrator for\nPipeline Safety\ndal\\192.3\\93-04-01","truncated":false,"body_characters":1534}
