by Erin Tiernan The state Department of Public Utilities on Wednesday lifted a moratorium on gas work by National Grid, but a series of new regulations means it’s unlikely development projects that have been stalled for months will be able to resume any time soon. Quincy is one of a handful of cities and towns that imposed its own local moratorium on all non-emergency gas work by National Grid after the company locked out 1,200 workers in June when contract negotiations broke down. It’s also a city in the midst of a massive development boom that is suffering as developers wait to finish projects that require gas connections. The state followed suit with its own moratorium on Oct. 8 after state regulators were spooked by an incident in Woburn in which gas lines were over-pressurized. A series of explosions in the Merrimack Valley a month earlier were also blamed on excessive pressure. Though the state on Wednesday lifted that moratorium, it ordered the utility to comply with what officials said is “an unprecedentedly high standard” as it proceeds with non-critical gas line work while workers are still locked out. The company would face hefty fines if it violates the new rules. National Grid has already said it will not perform any new service connections in Massachusetts until it is able to review and fully understand the scope of the new requirements and verify that it is interpreting them correctly. “We know we have current and hopeful customers that are awaiting gas service, and we apologize for delays,” National Grid spokeswoman Christine Milligan said in a statement. Milligan gave no timeline for when the utility company might resume making connections, but said the company is hoping to reach an agreement with union members before Christmas. In Quincy, there are several large apartment buildings and road re-paving projects that have been held up for months because they cannot get gas connections or gas line work completed. Though the city has instituted its own moratorium on National Grid gas work, Quincy mayor’s Chief of Staff Christopher Walker said that while the local moratorium would remain in place, the city is ready to start looking at and allowing projects on a case-by-case basis. “It’s gone on for far too long and it’s having very real impacts on the people of this community and on people across the commonwealth,” Walker said. Tamara Small, incoming CEO of NAIOP Massachusetts, a real estate trade group that represents commercial and residential developers across the state, said that she is pleased to see the moratorium lifted, but expressed doubts that National Grid could catch up with its backlog until it allows its union workers back on the job. “We obviously hope work will be able to move forward but in those sites where the state is requiring workers with a certain number of years of experience, I think it remains to be seen if those workers exist without ending the lockout,” she said. The order from the Department of Public Utilities would essentially apply the parameters of Gov. Charlie Baker’s gas safety bill and other new safety protocols to National Grid work. The order requires that any non-emergency National Grid gas work be reviewed by an engineer and given a professional engineer’s seal before taking place. The company will also be required to lay out step-by-step instructions for its work in “task specific operating procedures” and employees must now have specific levels of experience to conduct certain work. National Grid employees must now have at least five years of experience to conduct work on low-pressure gas service lines, 10 years of experience to work on intermediate-pressure service lines and 15 years of experience to work on high-pressure service lines, according to the administration. The order also requires the company to report each day to the the state’s Department of Public Utilities, or DPU, the number of inspectors present at every location where it conducted gas pipeline work. If National Grid does not follow the new directives, it will face fines of up to $200,000 per violation and $2 million for each continuing violation. The new restrictions apply only to National Grid for now, but an administration official said the parameters of the new requirements are similar to how the governor’s gas safety bill would be implemented across all utilities if the Legislature passes it. “We will be requesting further clarification from the DPU to ensure we can meet all expectations set forth in its letter,” Milligan of National Grid said in a statement.
