E. Purvis\nGleason Romans Pipe Line\nPatrol Company\nP. O. Box 51283\nTulsa, Oklahoma 74151\nDear Mr. Purvis:\nI wish to apologize for the lengthy delay in answering your letter. Your letter concerned various\napplications of the class location definitions located in Section 192.5 of the Minimum Federal Gas\nPipeline Safety Standards.\nIn your first question you asked whether the terminal point of a class 2 location would be 1/8 mile\nfrom the point where the last residence is located, or 1/8 mile from the nearest point on the\npipeline to the last residence.\nParagraph 192.5(c) states that a class 2 location is one where the class location unit has more than\nten but less than forty-sox buildings intended for human occupancy. The dividing point between a\nclass 2 and class 1 location, therefore; would be where the class location unit, as defined in\nParagraph 192.5(a), contains more than ten buildings.\nYour second question concerned three examples where two buildings or groups of buildings were\nlocated within one mile of each other but where there are a substantial distance between the two\nbuildings or groups of buildings. You requested our indication of the class location in each\nexample.\nIn your example, Figure 2(a), the \"ten units apartment\" and \"single unit\" would initially be\nclassified as a class 2 location due to having more than ten units. However, under sub-paragraph\n192.5(f)(3) this classification could be changed to a class location 220 yards both from the\napartment building and the single unit. This same reasoning would apply to your other two\nexamples, Figure 2(b) and Figure 2(c).\nthe definition of a gathering place that is occupied by twenty or more persons during normal use if\nleft to the reasonable consideration and judgment of the operator. The main point that the\noperator must consider is what the \" normal use\" of the building or area is. For example, a\nfactory which houses forty persons during an 8-hour shift per day operation would be considered\nby us to be a building occupied by twenty or more persons during normal use. A cemetery in a\nDB\nC:\\WP51\\INTERPRT\\192\\5\\71-08-05\n1\n\n<<<PAGE 2>>>\n\nsmall town used infrequently, on the otherhand, would not require the application of class 3\nrequirements, since the normal use of the cemetery would be for no living people to be present.\nThe answer to your last question, a place where twenty or more people work within 100 yards of\na pipeline would require that the line fulfill class 3 requirements.\nIf we can be of any further assistance, please let us know.\nSincerely,\n/signed/\nJoseph C. Caldwell\nActing Director\nOffice of pipeline Safety\nDB\nC:\\WP51\\INTERPRT\\192\\5\\71-08-05\n2","truncated":false,"body_characters":2682}
