Page 1February 26, 1976 Mr. T. K. Spalding Director, Gas Pipeline Safety Division West Virginia Public Service Commission Charleston, WV 25305 Dear Mr. Spalding: This responds to your letter dated November 5, 1975, in which you questioned "How often must individual anodes be monitored on an unprotected bare transmission or distribution pipeline that has 'hot spot' protection, which 'hot spot' protection would include the anodes installed in connection with corrosion-leak repair clamps?" Under 49 CFR Part 192, Subpart I, Requirements for Corrosion Control, there are no monitoring requirements for monitoring individual anodes. However, Sections 192.457 and 192.465 provide requirements for the corrosion control and monitoring of bare transmission or distribution pipelines. We trust that this will answer your question. Sincerely, Cesar DeLeon Acting Director Office of Pipeline Safety Operations dal\192\465\76-02-26 1#
