Re: Submittal of the Section 189(d) 5% Reasonable Further Progress PM-10 SIP Revisions 

for the Maricopa County and Apache Junction (Metropolitan Phoenix) Nonattainment 

Area 

Dear Mr. Nastri: 

Consistent with the provisions of Arizona Revised Statutes $9 49-104,49-404 and 49-406 

(Enclosure 1) and the Code of Federal Regulations, Title 40,$ $ 5 1.102 through 5 1.104 and 

Appendix V to Part 5 1, the Arizona Department of Environmental Quality (ADEQ) hereby 

adopts and submits to the U.S. Environmental Protection Agency (EPA), the 5% Plan for PM-I0 

for the Maricopa County Nonattainment Area [December] 2007, and Pinal County Resolution 

Nos. 12 1207-AQ1 and 121207AQ2 as revisions to the Ariz~na State Implementation Plan (SIP) 

to meet the December 3 1,2007, submittal deadline. 

Arizona obtained a 5-year extension of the attainment deadline for the referenced Serious 

Nonattainment Area through December 3 1,2006, in accordance with Section 188(e) of the Clean 

Air Act. Despite the adoption of Most Stringent Measures, in addition to Best Available Control 

Measures that had been adopted and implemented earlier, the area failed to attain the National 

Ambient Air Quality Standard (NAAQS) by the extended deadline. On June 6,2007, at 72 FR 

3 1 183, EPA finalized its findings that the Phoenix Serious PM- 10 Nonattainment Area had failed 

to attain the 24-hour (NAAQS) for particulate matter 10 microns in size or less by the applicable 

deadline. Section 189(d) requires that SIP revisions that provide for annual reductions of PM-10 

or PM-10 precursors of not less than 5% of the most recent emissions inventory, until the 

NAAQS is attained, be submitted to EPA by December 3 1,2007.

The enclosed SIP revisions, for portions of Maricopa County and Pinal County that comprise the 

Phoenix metropolitan area, demonstrate attainment by 201 0 through a combination of control 

measures and contingency measures. Numerous key stakeholders fiom both the private sector 

and government have participated in development of the SIP revision through a comprehensive 

collaborative effort, and with the strong support of Governor Napolitano the Arizona Legislature 

enacted Senate Bill 1552 earlier this year to facilitate attainment of the NAAQS as expeditiously 

as possible. ADEQ, the Maricopa County Air Quality Department, the Maricopa Association of 

Governments (MAG), and the Pinal County Air Quality Department continue to closely track 

monitored air quality in order to quickly respond to any evidence that the SIP revision is not 

adequate to achieve the NAAQS. ADEQ will continue to work with the MAG Air Quality 

Planning Team to implement and track implementation of the measures in the plan. 

Enclosure 2 is the SIP Completeness Checklist. Enclosure 3 contains two hard copies and one 

electronic copy of the 5% Plan for PM-10 for the Maricopa County Nonattainment Area 

[December] 2007, and five hard copies of Pinal County Resolution Nos. 121207-AQ1 and 

12 1207-AQ2 and related documents for your review and action. 

If you have any questions, please do not hesitate to contact Nancy Wrona, Director, Air Quality 

Division, at (602) 771 -2308.

Dear Mr. Nastri: 

As the designated Regional Air Quality Planning Agency, the Maricopa Association of Governments 

Regional Council adopted the MAG 2007 Five Percent Plan for PM- I0 for the Maricopa County 

Nonattainment Area on December 19, 2007. At this time, we are transmitting the MAG 2007 Five 

Percent Plan for PM- I0 for the Maricopa County Nottattainment Area to the Environmental Protection 

Agency by the federal deadline of December 3 I, 2007 for approval. 

In order to reduce PM- I 0, a broad range of commitments to implement measures were received from 

the State, Maricopa County, and the twenty-three local governments in the PM- I0 nonattainment area. 

Collectively, the Five Percent Plan for PM- I0 includes fifty-three committed control measures. The plan 

demonstrates that the committed measures will reduce PM- I0 emissions by at least five percent per year 

and demonstrates attainment of the PM- I0 standard as expeditiously as practicable which is 20 10. For 

conformity, the plan also contains the onroad mobile source emissions budget for 20 10. 

In accordance with the Clean Air Act, a public hearing was conducted on the plan on December 12, 

2007. The public hearing process documentation, including the response to comments, is contained in 

Appendix D, Exhibit I . For your convenience, two hard copies of the MAG 2007 Five Percent Plan for 

PM- I0 and one CD are provided. 

We are looking forward to working cooperatively with the Environmental Protection Agency in our 

continuing efforts to improve air quality. If you have any questions, please do not hesitate to contact Lindy 

Bauer or me at (602) 254-6300.
