by Catherine Carlock Lawmakers on Beacon Hill are set to review a bill sponsored by Gov. Charlie Baker that could spur the department of public utilities to lift its moratorium on non-emergency natural gas work throughout the commonwealth. Baker introduced the bill, titled “An Act to Ensure the Safety and Soundness of the Commonwealth’s Natural Gas Infrastructure,” on Nov. 20. Both the House and Senate have referred it to the committee on telecommunications, utilities and energy, which meets Tuesday. The bill would require all engineering plans for natural-gas work that could pose a risk to public safety to be reviewed and approved by a certified engineer. That change — which was recommended by the National Transportation Safety Board following the deadly Merrimack Valley gas explosions earlier this fall — could make the DPU more comfortable to lift the moratorium. “We are filing legislation to require certified professional engineers to review and approve natural gas work in order to provide another critical check and balance on the Commonwealth’s gas infrastructure,” Baker said in a statement to the Business Journal. “We look forward to working with our colleagues in the legislature to pass this legislation without delay in order to ensure continued safety of Massachusetts’ residents and energy infrastructure.” The commonwealth’s real estate development community has been in a panic over the combined impact of the moratorium and National Grid’s ongoing lockout of around 1,200 union workers. Most of Eastern Massachusetts is blocked from getting gas connections to commercial and residential real estate developments, and the slowdown has had a profound ripple effect on developments of all types across the region. National Grid officials and union representatives met this week, but did not reach an agreement. The groups are scheduled to meet again on Monday for another negotiating session. “We want to reach a deal by Christmas,” a National Grid spokesperson said in an email. Tamara Small, the incoming CEO of commercial real estate development association NAIOP Massachusetts, has called the issue “the biggest crisis to affect real estate development in the past 15 years. ” NAIOP said it will support Baker’s bill. “NAIOP is eager for the lockout to end, the moratorium to be lifted and, once that occurs, for DPU and National Grid to ensure that the backlog is addressed very quickly so projects can open,” Small said.
