Assistant Attorney General Air Quality Control Plan

Legislation/Regulations Section—Juneau (18 AAC 50.030)

Under AS 44.62.060, we have reviewed the attached amendment to regulations by the

Department of Environmental Conservation, and approve the changes for filing by the lieutenant

governor. I have reviewed this project under a specific delegation dated June 6, 2012 from the

Regulations Attorney. A duplicate original of this memorandum is being furnished to the

lieutenant governor, along with the one page of regulations and the related documents.

To facilitate the filing of those regulations that are ready the earliest, the department has

split this project into two parts. You might wish to contact the lieutenant governor’s office to

confirm the filing date and effective date of the attached regulation changes.

The March 4, 2012 public notice, the April 8, 2012 supplemental public notice, and the

May 29, 2012 adoption order all state that this action is not expected to require an increased

appropriation. Therefore, a fiscal note under AS 44.62.195 is not required.

In accordance with AS 44.62. 125(b)(6), a correction has been made to the regulations, as

shown on the attached copy.
