DEEP: Historical Version - Abatement of Air Pollution Regulations

Historical Regulatory Revisions and Hearing Reports
(for reference use only)

Regulations of Connecticut State Agencies (RCSA)
Sections 22a-174-1 to 22a-174-200
Abatement of Air Pollution

For reference purposes, the following table includes historical regulatory text for regulations amended before July 1, 2017, the date the eRegulation System became certified by the Secretary of the State.  Since July 1, 2017, the eRegulation System is the official version of the Regulations of Connecticut State Agencies and the electronic repository for the regulation-making records.
 
Each listed regulation section is provided in its current form in the left hand column.  The center column link provides the collected historical versions of the relevant regulatory section, listed by the effective date (The historical versions do not include the June 1972 regulations that are available as one PDF collection: 1972 Regulations). The right hand column provides available hearing reports.  Hearing reports include the comments submitted during the regulatory adoption process and the Departmentís responses to such comments and thereby provide insight into the Department's intention concerning regulatory language.
