Opportunity for Public Participation:

ADEC specifically invites the public to comment regarding a computer modeling technique used by ExxonMobil to estimate their one-hour nitrogen dioxide (NO₂) air quality impacts. The U.S. Environmental Protection Agency lists approved methods in their Guideline on Air Quality Models (Guideline).  ExxonMobil used the non-Guideline Ozone Limiting Method to refine their estimated one-hour NO₂ impacts. ADEC invites the public to comment regarding the use of this method.

Notice is also given that any interested person may present written statements relevant to the draft documents within 30 days after the first publication date. ADEC will consider all comments received and make any changes ADEC finds beneficial or necessary to assure compliance with 18 AAC 50 or State Law. ADEC will issue a final decision to issue or deny the permit after the close of the public comment period. Any person may request a public hearing and that hearing will be held if ADEC finds that good cause exists.
