Dr. John P. Carrol — Pipeline Safety Interpretation

Page 1August 1, 1975 Dr. John P. Carroll Route 1, Box 21 Gravois Mills, Missouri 65037 Dear Dr. Carroll: This refers to your letter of July 12, 1975, concerning the safe level that pipelines carrying gasoline should be buried. Enclosed is a copy of 49 CFR Part 195, Section 195.248 of which prescribes minimum cover requirements for construction of new, relocated, or replaced pipelines carrying hazardous liquids. cover requirements are not mandatory for pipelines in operation before April 1, 1970. The In general, the need for cover or other means of protecting a pipeline depends on conditions which may adversely affect its operation. We will be glad to investigate the safety of the lines in question at 55th and State Avenue, Kansas City, if you will first tell us the basis for your belief that the lines are currently placed at an unsafe level. What adversities are affecting their operation? In this regard, do you have a newspaper or other account of the explosion which occurred indicating its relation to operation of the pipelines in question? We appreciate your concern for pipeline safety. Sincerely, \signed\ Cesar DeLeon Acting Director Office of Pipeline Safety Operations dal\195\248\75-08-01 1#
