(c) The department shall review whether adjustments to the renewable heating standards for the following 2 compliance years are necessary to ensure that the increase in customer bills remains affordable. This review shall assess the total incremental annual cost to meet the renewable heating standards, including accounting for (i) any value received by a natural gas utility upon any resale of eligible resources, such as any environmental credits or other credits associated with environmental attributes; and (ii) any savings achieved through avoidance of conventional gas purchases or development, such as avoided pipeline costs or carbon costs. (d) The department may adjust prospective compliance year targets described in subsection (a); provided, however, that the cumulative annual percentage of natural gas sold shall comply with the 2035 target. (e) If the department determines that there are not enough eligible resources to meet the targets identified in subsection (a) within the constraints of subsections (b) to (d), inclusive, the department may recommend natural gas utilities develop qualified investments sufficient to meet the targets. (f) The department shall ensure that the reductions in carbon intensity in subsection (a) are consistent with Section 3A of Chapter 21N. Section 3. (a) Compliance of an obligated entity with the renewable heating standard may be demonstrated through: (i) sale of qualified renewable heating fuels or useful thermal energy from a renewable thermal resource and their associated environmental attributes to customers in Massachusetts; (ii) procurement of environmental attributes by obligated entities representing qualified GHG emissions reductions in a system of record designated by the department (iii) payment of alternative compliance payments to the renewable heating solutions development fund established in section 2PPPPP of chapter 29; or (iv) any combination of qualified renewable heating fuel procurement, renewable thermal resource procurement, environmental attribute procurement, or alternative compliance payments.. The commissioner shall promulgate rules and regulations for the payment of alternative compliance payments. (b) To procure environmental attributes an obligated entity’s production source shall be certified by the department as using eligible resources. Use of eligible resources shall be evidenced by reports issued by the commissioner of energy resources. (c) In meeting the obligations of the renewable heating standards, to the extent feasible and consistent with state and federal law, all investments, projects and activities undertaken pursuant to this chapter by any person or the department shall provide employment opportunities for all segments of the population and workforce, including minority-owned and female-owned business enterprises, and utilize labor and materials within the commonwealth to ensure the environmental benefits of avoided carbon emissions are not diminished by emissions associated with the transportation of labor or materials. The investments, projects and activities shall not discriminate based on race or socioeconomic status. (d) The commissioner of energy resources shall promulgate rules and regulations for the implementation of the renewable heating standards on or before July 1, 2025. The rules and regulations shall include, but be limited to, provisions for: (i) verification of eligibility and production of eligible resources, as well as the energy content of qualified renewable heating fuels and useful thermal energy from a renewable thermal resource, including requirements to notify the department in the event of a change in status, monitor qualified facilities to ensure annual average energy content matches the expected generation of environmental attributes; (ii) certification of eligible resources by issuing statements of qualification within 90 days of application, including prospective reviews for applicants seeking to determine whether a facility would be eligible; (iii) annual compliance filings to be made by all obligated entities within 1 month after tracking system data is available for the fourth quarter of each calendar year; provided, that all obligated entities shall cooperate with the department in providing data necessary to assess the magnitude of obligation and verify the compliance of all obligated entities; (iv) sanctions for obligated entities that, after investigation, have been found to fail to reasonably comply with the renewable heating standards or department rules and regulations; provided, that no sanction or penalty shall relieve or diminish an obligated entity from liability for fulfilling any shortfall in its compliance obligation; provided further, that no sanction shall be imposed if compliance is achieved through alternative compliance payments; provided further, that the department may suspend or revoke the certification of eligible resources that provide false information or fail to notify the department in the event of a change in eligibility status or otherwise comply with department rules; and provided further, that financial penalties resulting from sanctions from obligated entities shall not be recoverable in rates; (v) mechanisms for the purposes of easing compliance burdens, facilitating bringing new eligible resources on-line and avoiding or mitigating conflicts with state-level source disclosure requirements and green marketing claims throughout the region; provided, that mechanisms shall allow obligated entities to demonstrate compliance over a compliance year and bank excess compliance for 2 subsequent compliance years, capped at 20 per cent of the current year's obligation; and (vi) public reporting on the status of the implementation of standards, including the comparative use of environmental attributes and alternative compliance payments and the amount of rate increases authorized by the standards.
