RE: Submittal of State Implementation Plan Revision- Air Quality Rules Governing

Emissions from Existing and New Nonpoint Sources (Article 6);

Existing Stationary Source Performance Standards (Article 7); and

Emissions from Mobile Sources (New and Existing) (Article 8)

Dear Ms. Marcus:

The Arizona Department of Environmental Quality (ADEQ) is submitting for approval by the

U.S. Environmental Protection Agency (EPA), Region IX, five (5) copies of those portions of the

Arizona Administrative Code that update and complete the State Implementation Plan (SIP).

Approval of these administrative regulations will close the “SIP gap” that currently exists.

On August 15, 1994, ADEQ provided a SIP submission to EPA that covered Articles 1 through 5

(New Source Review/Prevention of Significant Deterioration) of the Arizona Administrative

Code, Title 18, Environmental Quality, Chapter 2, Department of Environmental Quality, Air

Pollution Control. Today’s submittal covers Articles 6, 7, and 8 (Emissions from Nonpoint

Sources, Existing Stationary Source Performance Standards, and Emissions from Mobile

Sources).

For your information, Articles 9 and 11 deal with Hazardous Air Pollutants. Article 10 relates to

the Vehicle Inspection Program. Article 14 is the Transportation Conformity Rule and will be

submitted as a SIP revision at a later date this year. Article 15 is the Prescribed Forestry Bum

rule. The following presents the progression from the original SIP to the current regulations and

details the actions that have occurred affecting and transforming the SIP. The pertinent

documents reflecting these actions are enclosed as appendices.

1977 SIP submitted to EPA by Arizona Department of Health Services (ADHS).
