This gas leak, currently on the books at #MassDPU as a grade 3 leak of Significant Environmental Impact (SEI), aka “superemitter”, and on the books as a known and documented leak at that address on June 20, 2022, when the injury explosion occurred, is the one that I discovered yesterday that was actually a grade 1 hazardous leak in an explosive condition. #DPUInvestigation

I’ve also learned that #MassDPU was mistaken in saying that NGrid is waiting on the #CityOfNewtonMA to fix the many leaks on Walnut Street. No Grant of Location request has been made to the City of Newton by NGrid for Walnut Street as of this writing.

I’m pleased to report that #MassDPU called me back today, although I was unable to pick up the call while on another call at work. I will return the call tomorrow morning.

Google “explosion Walnut Lakewood Newton” and you won’t get a single hit referencing the gas company, National Grid. But they quietly sent crews knocking on doors two nights after the explosion, to inspect basements, literally under the cover of darkness. And their unrepaired leaks were and are listed in its #MassDPU annual gas leaks filing. No one from the #CityOfNewton or any of the utilities have mentioned the possibility that leaking gas was a possible causal factor in the explosion.
