Step 6:
Review by Attorney General’s Office.
Step 7:
DEEP submits final draft of regulation with any changes based on comments received from members of the public and the administration.
Step 8:
DEEP submits regulations to legislative regulations review committee for their consideration.
Step 9:
Upon receiving approval from the Legislative Regulations Review Committee (LRRC), DEEP submits its final regulation to be posted on the Secretary of State’s eRegulations System.

DEEP is committed to making the environmental rulemaking process as transparent and participatory as possible. We ensure the public is properly notified of regulatory proposals and has an opportunity to comment on those proposals. This multi-step process goes through various governmental offices for their review and approval. All approved regulations are filed with the Office of the Secretary of the State (SOTS) and can be reviewed on the SOTS eRegulations System.

Public Comment

DEEP encourages public participation in its regulatory activities. DEEP issues a “Notice of Intent to Adopt/Amend Regulations," to begin the public portion of the rulemaking process. The public is given a minimum of thirty days to submit comments, beginning the day notice is posted to the SOTS eRegulations System. Written comments should be submitted through the SOTS eRegulations System. If commenting through SOTS is not accessible, written comments may be submitted to DEEP by mail, email, or hand-delivery.

A hearing may be held if properly requested or at DEEP’s own initiative. Oral comment is only received if an agency holds a public hearing. 

How DEEP Addresses Public Comments

DEEP prepares a Hearing Report summarizing any comments received at the end of the public comment period, drafts a final proposed regulation and revised fiscal note that is sent to the Office of the Attorney General before going to the Legislative Regulations Review Committee ("LRRC") for review.
