ACTION:

Final rule.

SUMMARY:

EPA is approving State Implementation Plan revisions submitted by the States of Connecticut, Massachusetts, and Rhode Island. These revisions establish 2002 base year emission inventories and reasonable further progress emission reduction plans for areas within these states designated as nonattainment of EPA's 1997 8-hour ozone standard. The intended effect of this action is to approve these states' 2002 Base Year Inventories and reasonable further progress (RFP) emission reduction plans, and to approve the 2008 motor vehicle transportation budgets and contingency measures associated with the RFP plans. EPA also is approving three rules adopted by Connecticut that will reduce volatile organic compound emissions in the state. This action is being taken in accordance with the Clean Air Act.

I. Background and Purpose

On September 20, 2010 (75 FR 57221), EPA published a Notice of Proposed Rulemaking (NPR) for the States of Connecticut, Massachusetts, and Rhode Island. The NPR proposed approval of 2002 base year emission inventories and reasonable further progress emission reduction plans for areas within these states designated as nonattainment of EPA's 1997 8-hour ozone standard. Additionally, the NPR proposed approval of the 2008 motor vehicle transportation budgets and contingency measures associated with the RFP plans. EPA also proposed approval of three rules adopted by Connecticut that will reduce volatile organic compound emissions in the state. In today's final rule we are approving the items for which we proposed approval in the NPR. Today's final rule was originally signed on May 2, 2012, but due to a clerical error was not published.

On April 30, 2004, EPA designated portions of the country as being in nonattainment of the 1997 8-hour ozone national ambient air quality standard (NAAQS) (69 FR 23858).[1] All parts of Connecticut, Massachusetts, and Rhode Island were designated as nonattainment for ozone, and all were classified as moderate. There were five nonattainment areas created that encompassed the entirety of these states, as shown in Table 1.

Table 1—8-Hour Ozone Nonattainment Areas in Connecticut, Massachusetts, and Rhode Island

MASpringfield (W. MA) areaBerkshire, Franklin, Hampden, Hampshire.
RIProvidence areaStatewide.

As discussed in our September 20, 2010 NPR, the Act contains air quality planning and control requirements for ozone nonattainment areas. For more information about these requirements and our evaluation of each state's means of addressing them, please refer to the more detailed analysis presented within the September 20, 2010 NPR.

II. 2002 Base Year Emission Inventories

A. What is a base year inventory and why are these states required to prepare one?

The Act contains a number of requirements for moderate ozone nonattainment areas. One requirement, found at section 182(a)(1) of the Act and made applicable to moderate ozone nonattainment areas through section 182(b), compels the preparation and submittal of a “comprehensive, accurate, current inventory of actual emissions from all sources.” In August, 2005, EPA published supplemental guidance for states to use in development of their base year inventories entitled, “Emission Inventory Guidance for Implementation of Ozone and Particulate Matter National Ambient Air Quality Standards (NAAQS) and Regional Haze Regulation” (EPA-454/R-05-001). This guidance describes for states the requirements for development of comprehensive emission estimates from stationary point and area sources, and from mobile on-road and non-road sources, such that complete emission inventories are available to support SIP development for the 8-hour ozone standard. Each state complemented these emission estimates from man-made sources with biogenic (naturally occurring) emission estimates from plants, trees, grasses and crops prepared by EPA. The guidance directs states to prepare their emission estimates on a “typical summer day” basis to reflect emissions that occur during high ozone episodes, which occur predominantly during the warm summer months.

As mentioned above, Connecticut, Massachusetts, and Rhode Island all contain ozone nonattainment areas designated as moderate for the 1997 8-hour ozone standard. Therefore, they were required to develop 2002 base year emission inventories of VOC and NOX, as these compounds react in the presence of heat and sunlight to form ozone.

B. Summary of 2002 Base Year Inventories

The 2002 VOC and NOX base year inventories prepared by Connecticut, Massachusetts, and Rhode Island are shown below in Tables 2a through 2e. EPA has concluded that these states have adequately derived and documented the 2002 base year VOC and NOX emissions for these areas, and our intention is to approve these inventories into the SIP for each state.

C. What action is EPA taking on these inventories?

We are approving the 2002 base year inventories listed in Tables 2a through 2e above.

III. Reasonable Further Progress Plans, Contingency Plans, and State VOC Rules

A. What is a Reasonable Further Progress (RFP) plan and why were these states required to prepare one?

A reasonable further progress (RFP) plan illustrates how an ozone nonattainment area will make emission reductions of a set amount over a given time period. EPA's Phase 2 implementation rule for the 1997 ozone standard interpreted how Section 182(b)(1) of the CAA would apply to areas designated as moderate (or higher) nonattainment of the 1997 8-hour ozone standard. See 40 CFR part 51 subpart X. Of relevance for Connecticut, Massachusetts and Rhode Island is what the Phase 2 rule required for areas with attainment dates greater than 5 years from designation that previously accomplished a 15% reduction in VOC emissions pursuant to one-hour ozone nonattainment requirements, as all three of these states meet these criteria. For such areas, the Phase 2 rule indicates that RFP will be met if the area can demonstrate a 15% reduction in ozone precursor emissions (VOC and/or NOX) will occur between 2002 and 2008.[2] See 40 CFR 51.910(b)(2)(ii)(A)-(B). These states prepared RFP plans for each of the nonattainment areas shown in Table 1 above, and our September 20, 2010 notice of proposed rulemaking contains a summary of these plans and the results of our evaluation of them.

B. What action is EPA taking on these RFP plans?

We are approving the RFP plans submitted by Connecticut, Massachusetts, and Rhode Island for the moderate ozone nonattainment areas shown in Table 1 above, as revisions to these states' SIPs. Note that regarding the NY-NJ-CT moderate area, we are taking action today only on the Connecticut portion of the RFP plan for that area. The VOC and NOX emission target levels and modeled, controlled 2008 emissions for each nonattainment area are shown within Table 3 below.

Table 3—2008 RFP Emission Target Levels and Modeled, Controlled Emissions

Nonattainment areaVOC emissions target; modeled 2008 emissions (tons/day)NOX emissions target; modeled 2008 emissions (tons/day)
NY-NJ-CT area184.6; 167.6167.9; 142.6
Greater Connecticut area159.4; 149.3130.0; 107.1
Bos-Law-Wor area588.1; 525.7562.7; 440.6
Springfield area94.4; 84.292.0; 66.9
Providence area113.7; 115.457.8; 55.3

Note that in Table 3 above, all of the modeled 2008 emission levels are lower than the corresponding 2008 emission target levels with the exception of the Providence area's VOC emissions which are 1.5% higher than the 2008 VOC target. In light of this, Rhode Island allocated an additional 1.5% NOX reduction (which translates to 1.1 tons) to cover this shortfall. Thus, Rhode Island has set its 2008 NOX target to 57.8 tons/day rather than 58.9 tons/day. In essence, Rhode Island has selected a 16.6% reduction in NOX emissions and a 1.5% increase in VOC emissions, resulting in a combined reduction of 15.1%. A more detailed discussion of this is contained within our September 20, 2010 proposal.

Additionally, a typographical error within our September 20, 2010 proposal occurred within step 6 of Table 3d, where the detailed RFP target level calculations for the Springfield area are shown. The error is that the information for step 5 is repeated and appears as step 5 and also as step 6, resulting in the correct information for step 6 not being shown. The correct step 6 information that should have been shown within our September 20, 2010 action for VOC emissions in tons/day is: 100.2 − 5.8 = 94.4; and for NOX emissions, also in tons/day, is: 113.1 − 21.1 = 92.0.

C. Is EPA approving any state control measures in this action?

We are approving three VOC control measures from Connecticut. Two of these rules consist of amendments to existing rules. The two amended rules are a solvent metal cleaning rule, located at section 22a-174-20(l) of the Regulations of Connecticut State Agencies, and the second rule is the state's asphalt paving rule, located at 22a-174-20(k) of the Connecticut regulations. We are approving the amended solvent metal cleaning rule and the amended asphalt paving rule as they were submitted to EPA, with the exception of the bracketed text as that language represents regulatory text from a prior version of the rule which Connecticut has retracted. The third rule we are approving is Connecticut's architectural and industrial maintenance (AIM) coatings rule, located at section 22a-174-41 of the Connecticut regulations. The solvent metal cleaning and AIM coatings rules have compliance dates in May of 2008, and so achieve emission reductions that help Connecticut demonstrate compliance with its RFP obligation. The amendment to the asphalt paving rule has a May 1, 2009 compliance date and was submitted to help the state demonstrate that it meets the Clean Air Act section 182(b)(2) requirement that sources in the state use reasonably available control technology (RACT) to control air pollution. We are not taking action on Connecticut's overall RACT or reasonably available control measure (RACM) submittals at this time. Additional details regarding our approval of these three Connecticut rules are available within our September 20, 2010 proposal. Our approval of these rules makes them part of Connecticut's federally enforceable SIP.

D. Have these states met their contingency measure obligation?

Section 172(c)(9) of the CAA requires, in part, that nonattainment areas provide for contingency measures “to be undertaken if the area fails to make reasonable further progress, or to attain the national primary ambient air quality standard by the attainment date applicable under this part.” As noted in our September 20, 2010 proposal, for Connecticut and Massachusetts we are approving each state's use of the surplus emission reductions that are documented within their RFP emission target level calculations.

For Rhode Island, we are approving use of the emission reductions from two stationary source measures as meeting the state's contingency plan requirement. In 2009, Rhode Island adopted VOC control regulations establishing emission limits for consumer and commercial products, and for architectural and industrial maintenance coatings. A public hearing on these proposed rules was held on February 20, 2009, and they were promulgated as final state regulations May 15, 2009, with an effective date of June 4, 2009. Rhode Island submitted these regulations to EPA as SIP revisions, and we approved them in a direct final rule published in the Federal Register on March 13, 2012 (77 FR 14691).

E. How do these plans affect transportation conformity?

Section 176(c) of the CAA, and EPA's transportation conformity rule at 40 CFR part 93 subpart A, require that transportation plans, programs, and projects conform to state air quality implementation plans. States are required to establish motor vehicle emission budgets in any control strategy SIP that is submitted for attainment and maintenance of the NAAQS. The RFP plans submitted by Connecticut, Massachusetts, and Rhode Island are control strategy SIPs, and they contain 2008 motor vehicle budgets for VOCs and NOX by nonattainment area. Table 4 contains these VOC and NOX transportation conformity budgets in units of tons per summer day:

Table 4—Conformity Budgets in the Connecticut, Massachusetts, and Rhode Island RFP Plans

Area name2008 Transportation conformity budgets (tons/day)
VOCNOX
NY-NJ-CT area (CT portion)29.760.5
Greater Connecticut28.554.3
Bos-Law-Wor (E. MA) area68.30191.30
Springfield (W. MA) area11.8031.30
Providence24.6428.26

In today's action, we are approving the 2008 conformity budgets for VOC and NOX for the areas shown in Table 4 above.

Other specific requirements of these state's inventories, RFP plans, and Connecticut's VOC control regulations and the rationale for EPA's proposed action are explained in the NPR and will not be restated here. No public comments were received on the NPR.

IV. Final Action

EPA is approving 2002 emission inventories and reasonable further progress plans as revisions to the Connecticut, Massachusetts, and Rhode Island SIP. We are also approving the 2008 motor vehicle emission budgets and contingency measures associated with these RFP plans. Additionally, we are approving three Connecticut VOC control regulations, Sections 22a-174-20(k), 22a-174-20(l), and 22a-174-41 as revisions to the Connecticut SIP.

V. Statutory and Executive Order

Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. 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:

  • 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 information 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 of small 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 Reform Act of 1995 (Pub. L. 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 Clean Air Act; and
  • Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible 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 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 defined by 5 U.S.C. 804(2).

Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by October 22, 2012. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial 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 may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)

* * * * *

(e) The state of Rhode Island submitted base year emission inventories representing emissions for calendar year 2002 from the Providence moderate ozone nonattainment area on April 30, 2008 as revisions to the State's SIP. The 2002 base year emission inventory requirement of section 182(a)(1) of the Clean Air Act, as amended in 1990, has been satisfied for this area. The inventory consists of emission estimates of volatile organic compounds and nitrogen oxides, and cover point, area, non-road mobile, on-road mobile and biogenic sources. The inventory was submitted as a revision to the SIP in partial fulfillment of obligations for nonattainment areas under EPA's 1997 8-hour ozone standard.

9. Section 52.2088 is amended by adding paragraph (e) to read as follows:

Control strategy: Ozone.
* * * * *

(e) Revisions to the State Implementation Plan submitted by the Rhode Island Department of Environmental Management on April 30, 2008. The revision is for the purpose of satisfying the rate of progress requirement of section 182(b)(1) from 2002 through 2008, and the contingency measure requirement of sections 172(c)(9) and of the Clean Air Act, for the Providence moderate ozone nonattainment area. The revision establishes motor vehicle emission budgets for 2008 of 24.64 tons per day of volatile organic compounds and 28.26 tons per day of nitrogen oxides to be used in transportation conformity in the Providence moderate 8-hour ozone nonattainment area.

2.  If the area wishes to use NOX reductions to meet part or all of this 15% requirement, the calculation is not done by measuring the overall percent of combined VOC and NOX reductions, but rather by separately calculating the percent of VOC reductions and the percent of NOX reductions, and adding those percentages together.
