Washington, D.C. 20590 Re: Subpart I of Federal Safety\nStandards; Subject Corrosion\ncontrol\nDear Sir:\nPlease accept this letter as a petition to seek a waiver for compliance of Subpart I of the Federal\nSafety Standards concerning corrosion control.\nAt this time, the City of Bay City has only a few areas which have electrolysis and we have begun\na program of changing out existing corroded lines with plastic pipe. This will eliminate need for\nelectrodes in these areas.\nSince plastic pipe is more economical than steel pipe and does not have corrosive qualities, the\npublic will be better served by the City using plastic pipe.\nThe City of Bay City's gas lines are for the most part very old and we are today having the system\ncompletely checked for leaks. After the survey, we will determine which part of the system needs\nupgrading, and begin a systematic program of replacement.\nWe have contacted people in the cathodic protection field and are beginning negotiations to put\nthe required portion of the system under cathodic protection.\nWe have just recently (1975) changed department heads and the present department heads are\nstudying the necessary requirements and all safety acts will be complied with at the earliest\nopportunity.\ndal\\192\\457\\76-05-21\n2\n\n<<<PAGE 3>>>\n\nWe respectfully request a waiver from the time period of August 1, 1976 until August 1, 1981,\nwhich will give the company time to comply with regulations.\nSincerely,\nMildred Nelsen\nSupt. of Utilities\ndal\\192\\457\\76-05-21\n3","truncated":false,"body_characters":2412}
