MTB RECOGNIZES THAT THIS IS ONLY PART OF THE INTENT OF THE RECOMMENDATION.

Addressee Acronym: RSPA Addressee Organization Type: G-Federal Government Communication Date: 1982-06-25 Communication Type: Official Correspondence Communication Contents: RESEARCH & SPECIAL PROGRAMS ADMINISTRATION LTR: WE DO NOT BELIEVE IT FEASIBLE TO ATTEMPT TO MANDATE BY REGULATION A PRECISE SET OF PROTECTIVE MEASURES WHICH PIPELINE OPERATORS MUST TAKE TO ENSURE THEIR FACILITIES FROM THE RISK OF POSSIBLE DAMAGE DUE TO BLASTING IN THE VICINITY. NEVERTHELESS, WE FEEL THE POTENTIAL FOR HARM AND CONSEQUENT DAMAGES CAN BE REDUCED SIGNIFICANTLY IF OPERATORS COMMUNICATE IN ADVANCE WITH BLASTERS AND MONITOR THEIR PIPELINES AFTER BLASTING OCCURS. THESE STEPS CAN BE ACCOMPLISHED THROUGH 0PERATOR PARTICIPATION IN A DAMAGE PREVENTION PROGRAM SUCH AS A "ONE-CALL" SYSTEM. THEREFORE, MTB HAS INCLUDED IN THE FINAL RULE IN DOCKET PS 59, "DAMAGE PREVENTION PROGRAM," REQUIRED STEPS THAT AN OPERATOR MUST TAKE WHENEVER BLASTING OPERATIONS MIGHT AFFECT THE PIPELINE. WE BELIEVE THIS APPROACH SHOULD BE GIVEN AN OPPORTUNITY BEFORE ANY FURTHER CONSIDERATION IS GIVEN TO ADDITIONAL MANDATORY REGULATION OR PIPELINE OPERATORS. CONSEQUENTLY WE HAVE REMOVED THE SCHEDULED RULEMAKING ON BLASTING FROM OUR AGENDA.
