The Massachusetts Dept. of Public Utilities hired Dynamic Risk Assessment Systems Inc. on Nov. 1 to analyze the state's entire gas distribution system. The Texas-based firm will also look into the operational and maintenance functions of natural gas companies operating in Massachusetts.
The hire comes about six weeks after the state announced that it would hire an independent firm to examine the natural gas distribution system in the wake of a series of spectacular gas explosions in the Merrimack Valley on Sept. 13.
