Massachusetts has no state-level GLB ban. MassDEP's 310 CMR 7.10 noise regulation exempts "domestic equipment such as lawn mowers and power saws" between 7am and 9pm — functionally a backstop rather than a front-line rule. Three 193rd-session incentive bills (S.555, H.909, H.3055) to create grant/loan/tax-credit programs for gas-to-electric swaps all died in committee; no 194th-session successor has advanced. All substantive regulation is municipal — 20+ cities and towns across Middlesex, Norfolk, Essex, Nantucket, and Dukes counties. Attorney General Municipal Law Unit approves town bylaws under G.L. c. 40 §32.
