Questions

MEPA ENF Threshold Check for Massachusetts: what people ask

Who files the ENF?

The proponent completes and files the ENF, circulates it, and publishes public notice.

How long is the comment period?

Comments are due within 20 days after the ENF notice is published in the Environmental Monitor. The Secretary then issues a certificate saying whether an EIR is required.

What if environmental justice populations are nearby?
