Approval and Promulgation of Implementation Plans and Designations of Areas for Air Quality

Planning Purposes; Tennessee: Knoxville; Determination of Attaining Data for the 1997 8-Hour

Ozone Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

SUMMARY: On February 19, 2010, the State of Tennessee, through the Tennessee Department

of Environment and Conservation (TDEC), submitted a request to EPA to make a determination

that the Knoxville, Tennessee nonattainment area for the 1997 8-hour ozone National Ambient

Air Quality Standards (NAAQS) has attained these standards based on quality assured, quality

controlled monitoring data from 2007 through 2009. The Knoxville 1997 8-hour ozone

nonattainment area is comprised of Anderson, Blount, Jefferson, Knox, Loudon, and Sevier

Counties in their entireties, and the portion of Cocke County that falls within the boundary of the

Great Smoky Mountains National Park (hereafter referred to as "the Knoxville Area"). In this

action, EPA is taking final action to determine that the Knoxville Area has attained the 1997 8-

hour ozone NAAQS. This determination is based upon complete, quality assured, quality

controlled, and certified ambient air monitoring data for the years 2007-2009 showing that the

Knoxville Area has monitored attainment of the 1997 8-hour ozone NAAQS. This final action is

consistent with the CAA, and EPA policy and guidance.
EFFECTIVE DATE: This final rule is effective on [insert date of publication in the Federal

Register].

I. What Action is EPA Taking?

EPA is determining that the Knoxville Area (comprised of Anderson, Blount, Jefferson,

Knox, Loudon, and Sevier Counties in their entireties, and the portion of Cocke County that falls

within the boundary of the Great Smoky Mountains National Park) has attaining data for the

1997 8-hour ozone NAAQS. This determination is based upon quality assured, quality

controlled and certified ambient air monitoring data that shows the Knoxville Area has

monitored attainment of the 1997 8-hour ozone NAAQS based on the 2007-2009 data.

Other specific requirements of the determination and the rationale for EPA's final action

are explained in the notice of proposed rulemaking (NPR) published on August 3, 2010 (75 FR

45568) and will not be restated here. The comment period closed on September 2, 2010. No

comments, adverse or otherwise, were received in response to the NPR.

II. What is the Effect of this Action?

This final action, in accordance with 40 CFR 51.918, suspends the requirements for this

area to submit attainment demonstrations, associated reasonably available control measures

(RACM), reasonable further progress plans (RFP), contingency measures, and other planning

SIPs related to attainment of the 1997 8-hour ozone NAAQS as long as this Area continues to

3
meet the 1997 8-hour ozone NAAQS. Finalizing this action does not constitute a redesignation

of the Knoxville Area to attainment for the 1997 8-hour ozone NAAQS under section 107(d)(3)

of the Clean Air Act (CAA). Further, finalizing this action does not involve approving

maintenance plans for the Area as required under section 175A of the CAA, nor does it involve a

determination that the Area has met all requirements for a redesignation.

III. What is EPA's Final Action?

EPA is determining that the Knoxville Area has attaining data for the 1997 8-hour ozone

NAAQS. This determination is based upon quality assured, quality controlled, and certified

ambient air monitoring data showing that the Knoxville Area has monitored attainment of the

1997 8-hour ozone NAAQS during the period 2007-2009. This final action, in accordance with

40 CFR 51.918, will suspend the requirements for this Area to submit attainment demonstrations,

associated RACM, RFP plans, contingency measures, and other planning SIPs related to

attainment of the 1997 8-hour ozone NAAQS as long as the Area continues to meet the 1997 8-

hour ozone NAAQS.

IV. What is the Effective Date?

An expedited effective date for this action is authorized under both 5 U.S.C. 553(d)(1),

which provides that rule actions may become effective less than 30 days after publication if the

rule "grants or recognizes an exemption or relieves a restriction" and section 5 U.S.C. 553(d)(3),

which allows an effective date less than 30 days after publication "as otherwise provided by the

agency for good cause found and published with the rule." EPA finds that there is good cause for

4
this approval to become effective upon publication.

Approval of a clean data determination relieves the obligation for the State of Tennessee

to submit for the Knoxville Area an attainment demonstration and associated RACM, RFP plan,

contingency measures, and any other SIP-related planning requirements to attainment of the 1997

8-hour ozone NAAQS provided the Area does not monitor any violations of the ozone standard.

The relief from these obligations is sufficient reason to allow an expedited effective date of the

rule under 5 U.S.C. 553(d)(1). In addition, Tennessee's relief from these obligations provides

good cause to make this rule effective immediately upon publication, pursuant to 5 U.S.C.

553(d)(3). The purpose of the 30-day waiting period prescribed in 5 U.S.C. 553(d) is to give

affected parties a reasonable time to adjust their behavior and prepare before the final rule takes

effect. Where, as here, the final rule relieves obligations rather than imposes obligations,

affected parties, such as the State of Tennessee and the Knox County Department of Air Quality

Management, do not need time to adjust and prepare before the rule takes effect.

v. What are Statutory and Executive Order Reviews?

Under the CAA, the Administrator is required to approve a SIP submission or State

request that complies with the provisions of the Act and applicable Federal regulations. 42

U.S.C. 741O(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions or state requests, EPA's

role is to approve state choices, provided that they meet the criteria ofthe CAA. Accordingly,

this action merely approves state law as meeting Federal requirements and does not impose

additional requirements beyond those imposed by state law. For that reason, this action:

5
• is not a "significant regulatory action" subject to review by the Office of Management and

Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);

• does not impose an infonnation collection burden under the provisions of the Paperwork

Reduction Act (44 U.S.c. 3501 et seq.);

• is certified as not having a significant economic impact on a substantial number ofsmall

entities under the Regulatory Flexibility Act (5 U.S.c. 601 et seq.);

• does not contain any unfunded mandate or significantly or uniquely affect small

governments, as described in the Unfunded Mandates Refonn Act of 1995 (Public Law

104-4);

• does not have Federalism implications as specified in Executive Order 13132 (64 FR

43255, August 10, 1999);

• is not an economically significant regulatory action based on health or safety risks subject

to Executive Order 13045 (62 FR 19885, April 23, 1997);

• is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355,

May 22, 2001);

• is not subject to requirements of Section 12(d) of the National Technology Transfer and

Advancement Act of 1995 (15 U.S.c. 272 note) because application of those

requirements would be inconsistent with the CAA; and

• does not provide EPA with the discretionary authority to address, as appropriate,

disproportionate human health or environmental effects, using practicable and legally

pennissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).

In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65

6
FR 67249, November 9,2000), because the SIP is not approved to apply in Indian country

located in the state, and EPA notes that it will not impose substantial direct costs on tribal

governments or preempt tribal law.

The Congressional Review Act, 5 U.S.c. 801 et seq., as added by the Small Business

Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take

effect, the agency promulgating the rule must submit a rule report, which includes a copy of the

rule, to each House of the Congress and to the Comptroller General of the United States. EPA

will submit a report containing this action and other required information to the U.S. Senate, the

U.S. House of Representatives, and the Comptroller General of the United States prior to

publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after

it is published in the Federal Register. This action is not a "major rule" as defmed by 5 U.S.C.

804(2).

Under section 307(b)(l) of the CAA, petitions for judicial review of this action must be

filed in the United States Court of Appeals for the appropriate circuit by [Insert date 60 days from

date of publication of this document in the Federal Registerl. Filing a petition for

reconsideration by the Administrator of this fmal rule does not affect the fmality of this action for

the purposes ofjudicial review nor does it extend the time within which a petition for judicial

review may be filed, and shall not postpone the effectiveness of such rule or action. This action,

pertaining to the determination of attaining data for the 1997 8-hour ozone standard for the

Knoxville Area, may not be challenged later in proceedings to enforce its requirements. (See

section 307(b)(2».
