Finnan\nSupervisor, Gas Safety Division\nBureau of Transportation and Safety\nPennsylvania Public Utility Commission\nP.O. Box 3265\nHarrisburg, PA 17105\nDear Mr. Finnan:\nThis responds to your letter of December 18, 1995, asking whether American Meter Regulator\nModel 1833, when used as a district regulator, complies with 49 CFR § 192.199(g). Model 1933\nincorporates control and overpressure protection in the same body. Section 192.199(g) requires a\nregulator, when used as a district regulator, to be designed and installed to prevent any single\nincident such as an explosion in a vault or damage by a vehicle from affecting the operation of\nboth the overpressure protection device and the regulator.\nWe have reviewed the July1 3, 1995, letter from John O. Graham, General Manager, North East\nHeat & Light Co. concerning the installation of Model 1933 at regulator station #1 at Weaver's\nHillside Mobile Homes. The letter fails to explain how Model 1933, which incorporates the\noverpressure assembly as part of the regulator, would be precluded from a single incident such as\nan explosion in a vault or damage by a vehicle from affecting the operation of both the\noverpressure protection device and the regulator.\nIn the absence of any additional rationale, we agree with you that the installation does not comply\nwith § 192.199(g).\nSincerely,\nRichard D. Huriaux, P.E.\nDirector for Technology and Regulations\nOffice of Pipeline Safety\nLWUlrich:jmd:64046:2-21-96\ncc: DPS-1,2,10,Regions,TSIEMail,StateMailing\n05/12/99 192.199\n96-02-21.doc","truncated":false,"body_characters":1562}
