Wiggs Marketing Manager Heath Consultants Incorporated 100 Tosca Drive Stoughton, MA 02072 Dear Mr. Wiggs: Thank you for your letter of October 3, 1974, asking whether public housing authorities are required to perform gas leakage surveys and, if so, how often. Where a public housing authority purchases gas from a public utility, and then sells and distributes the gas through its own mains and service lines to customers who may or may not be metered, the housing authority is the operator of a gas distribution system and is subject to the requirements of 49 CFR Part 192 (copy enclosed). Section 192.723, in conjunction with sections 192.603(b) and 192.13(c), requires an operator of a distribution system to periodically conduct leakage surveys. In business areas, a survey must be conducted at intervals of 1 year or less. Elsewhere, surveys must be conducted as often as necessary but not less frequently than at 5- year interval; We trust this satisfactorily responds to your inquiry. Sincerely, SIGNED Joseph C. Caldwell Director Office of Pipeline Safety <<>> Heath Consultants Incorporated 100 Tosca Drive Stoughton, Massachusetts 02072 October 3, 1974 Office of Pipe Line Safety Department of Transportation Office of the Secretary Washington, D. C. 20590 Gentlemen: Would you please define for us the responsibilities of Public Housing Authorities in performing gas leakage surveys in and around their properties? We are particularly interested in knowing if there is a regulation requiring these housing authorities to perform such inspections on a periodic basis, and if so, how often these inspections must be performed. Thank you for your help with this matter. We look forward to your response. Sincerely, John W. Wiggs Marketing Manager - **truncated:** false - **body characters:** 1820
