Policy January 06, 2017

In response to the safety study on Integrity Management of Gas Transmission Pipelines in High Consequence Areas, the National Transportation Safety Board (NTSB) issued a series of recommendations, four of which were directed to the American Gas Association (AGA) and Interstate Natural Gas Association of America (INGAA). Two of these recommendations directed AGA and INGAA to work with each other “to develop and implement a strategy for increasing the use of in-line inspection tools as appropriate, with an emphasis on intrastate pipelines.” (P-15-24 and P-15-26)
