On December 12, 2003, RSPA/OPS published a notice of proposed rulemaking in the Federal Register (68 FR 69368) to amend the pipeline safety regulations at 49 CFR parts 192 and 195 to require owners and operators of pipeline facilities to develop procedures to conduct periodic underwater depth of burial inspections of underwater pipelines. The procedures would assess the risk of a pipeline becoming exposed or a hazard to navigation by taking into account the dynamics of the waterway, including the probability of flotation, scour, erosion, and major storms. The operator would also be required to establish a risk-based timetable for inspection of underwater pipelines.

In response to the NPRM the Interstate Natural Gas Association of America (INGAA) submitted a request for extension of the comment period. It noted that the end of year holidays and ongoing efforts to implement other regulatory requirements minimized the opportunity for the public to provide meaningful comments on the NPRM by the published due date.
