Federal Rulemaking

Comments on Federal Actions

In an effort to ensure that federal actions are responsive to our state's needs and concerns, DEEP submits comments to EPA on proposed federal actions that impact the air quality of Connecticut, the Northeast and the entire United States.  EPA provides a number of tools for you to track and participate in the development of new regulations, and to learn how to comply with existing regulations. 

The comments below have been submitted to EPA by DEEP on various federal rules.  (All documents are in pdf format unless noted otherwise.)
