Cumulative Impacts Analysis
In March 2021, Governor Baker signed Chapter 8 of the Acts of 2021, An Act Creating a Next Generation Roadmap for Massachusetts Climate Policy. The Act requires the MEPA Office to develop new regulations by the end of 2021 that would require:
- Submission of an environmental impact report (EIR) for any project that is likely to cause damage to the environment and is located near an environmental justice (EJ) population;
- Assessment of potential existing unfair or inequitable environmental burden and related public health consequences for the EJ population; and
- Analysis of how the proposed project might result in a disproportionate adverse effect on the EJ population.
The Act also directed the Department of Environmental Protection (MassDEP) to incorporate cumulative impact analysis (CIA) for certain categories of air permits and approvals. MassDEP was directed to propose regulations for accomplishing this goal by 2022.
The MEPA Office will participate in MassDEP's stakeholder effort to evaluate and seek public comment on development of a CIA methodology. More information is available here.
