Subject: Certification of SIP Elements for the 2006 24-hour PM2.5 NAAQS under Clean

Air Act Sections llO(a)(l)-(2)

Dear Dr. Armendariz:

In a letter dated March 30, 20 II, Governor Mary Fallin appointed me as her designee for

the purpose of submitting documents to the U.S. Environmental Protection Agency

(EPA) for approval and incorporation into the State Implementation Plan (SIP) for the

State of Oklahoma.

Section 11O(a)(I) and (2) of the Clean Air Act required that states review and revise as

necessary their SIP following EPA's 2006 promulgation of a revised 24-hour PM25

National Ambient Air Quality Standard (NAAQS). EPA issued the "Guidance on SIP

Elements Required Under Sections I lO(a)(I) and (2) for the 2006 24-hour Fine Particle

(PM2.

5) National Ambient Air Quality Standards (NAAQS)" on September 25, 2009.

Under this guidance, states may certify that their existing SIPs meet the "infrastructure"

elements of Section llO(a)(2), rather than submitting a revised SIP for the PM25

NAAQS.

Oklahoma's SIP is codified in 40 CFR Part 52, Subpart LL. As indicated in the enclosed

table titled "Oklahoma's State Implementation Plan (SIP) Submittal 'Infrastructure'

Checklist," Oklahoma's SIP meets the infrastructure obligations for the 2006 24-Hour

PM25 standard. It is our understanding that the final results of EPA's review of this

submittal will be determined through rulemaking and will be published in the Federal

Register.

This letter and its supporting documentation do not address section 110(a)(2)(I), which

pertains to the nonattainment planning requirements of Title I, Part D of the Clean Air

Act and is not governed by the three year SIP submission deadline under section

lIO(a)(1), because Oklahoma currently has no PM25 nonattainment areas and no

nonattainment plans are due.

addressed in a separate, previous submittal.

Updated for the 2006 24·Hour PMZ•

5 National Ambient Air Quality Standard

A State Implementation Plan (SIP) identifies how that state will attain and/or maintain the primary and secondary National Ambient Air Quality

Standards (NAAQS). The SIP contains state regulations, source-specific requirements, and non-regulatory items such as plans and inventories. The

initial SIPs for states were approved by the U.S. Environmental Protection Agency (EPA) on May 31, 1972 (46 FR 40005). The federally

enforceable SIP for Oklahoma is compiled in 40 CFR Part 52, Subpart LL, including revisions approved on December 29, 2008 (73 FR 79400).

Approval of additional submittals is pending. The miscellaneous requirements of Section 11O(a)(2)(A)-(M) of the Clean Air Act (CAA) relevant to

the National Ambient Air Quality Standards (NAAQS) are addressed in the current SIP or pending SIP revisions. The following table summarizes

where these "infrastructure" requirements of Section 11O(a)(2)(A)-(M) are addressed.

SIPs are reviewed and revised by the state from time to time as necessary to accommodate changes in State and Federal statutes, rules, policies, and

program requirements. CAA Section 11O(a)(1) requires the state to review and revise the SIP as necessary each time a NAAQS is issued or revised.

In addition to SIP revisions to address specific program requirements (e.g., PSDINSR Program), EPA requires the state to demonstrate that the " ...

plan provides for implementation, maintenance and enforcement of ..." each NAAQS. In addition to a summary of infrastructure elements as they

relate to the various existing NAAQS, the table lists any changes or pertinent information specific to the subject change.

This NAAOS Revision:

Any transport issues specific to the 2006 24-Hour PM2., NAAQS would be

addressed through a separate SI P submission. However, EPA's analysis

for the proposed Transport Rule (75 FR 4521 0, 8/2/2010) indicates that, for

the 2006 24-Hour PM2' NAAQS, Oklahoma does not contribute significantly

to nonattainment in, nor interiere with maintenance by, any other stateI ,

beginning on page 45255)

Any specific PM2,-related issues related to Oklahoma's pennitting program

(e.g., PM2' increments and significance impact levels) would be addressed

through a separate submission.

Oklahoma's Regional Haze Implementation Plan Revision, submitted in

Guidance provided by EPA (dated 3/24/2008) expresses EPA's intent to

propose a Significant Harm Level (SHL) for PM,., of 500 ~g/m' (24-hour

maximum), with Priority I (& IAi and II classification levels of 210.5 - 280.4

~g/m' and 140.5 - 210.4 ~g/m , respectively. Oklahoma's EEP will be

updated once EPA has promulgated the SHL for PM,., in 40 CFR §51.151

and the priority ciassification ievels in 40 CFR §51.150, as well as the

episode criteria in Appendix L to Part 51. It should be noted that the highest

monitored PM,., vaiue for the 3 years of 2007 to 2009 was 53.1 ~g/m'

(latest certified data), which is well below the expected Priority II
