Rockefeller had cosponsored many of the proposals included in the law, which took effect last January. But he said officials need to look into strengthening the law.
"Passing comprehensive pipeline safety legislation was a good step, but I did push for even stronger provisions in that bill - and we must assess where implementation of that law stands, and whether future actions are needed," he said.
Officials will also use the hearing to review the findings of a new Government Accountability Office study researching transmission pipeline operators' ability to respond to a hazardous liquid or gas release.
Rockefeller said that study is due to be released Jan. 23.
Additional hearing details - including time, location and a witness list - will be announced at a later date.
"This will be the fourth Senate Commerce Committee hearing on this issue during my tenure as chairman, and it's an important one to West Virginia - because we know how much worse things could have been in Sissonville," Rockefeller said.
"And West Virginians want to know everything is being done to prevent accidents - and disasters."
