Re: Connecticut State Implementation Plan with Regard to the

Infrastructure Requirements ofClean AirAct Section 110(a)(1) and (2) for the

2010 Nitrogen Dioxide National AmbientAir Quality Standards

Dear Mr. Conroy:

Pursuant to Clean Air Act (CAA) section 110(a)(1) and (2), all states are required to submit

plans to implement, maintain and enforce the 2010 nitrogen dioxide (N02) primary national

ambient air quality standards (NAAQS), including such basic requirements as emissions

inventories, monitoring and modeling to assure attainment and maintenance ofthe NAAQS.

As described in the enclosed explanation, Connecticut's State Implementation Plan (SIP), as

identified in 40 CFR 52, subpart H, satisfies the required CAA section 110(a)(1) and (2)

infrastructure requirements for the 2010 primary N02 NAAQS after completion ofthe identified

regulatory updates. This submission also includes the necessary documents to satisfy the public

participation requirements of 40 CFR 51, Appendix V, Section 2.1. The structure ofthis

submission is as follows:

• Enclosure A: Explanation ofthe Adequacy ofConnecticut's SIP with Regard to the

Infrastructure Elements for the 2010 Primary N02NAAQS

• Enclosure B: Connecticut General Statutes (CGS) section 1-85, satisfying the conflict of

interest requirements of CAA Section 128(a)(2), as specified by CAA Section

110(a)(2)(E)

• Enclosure C: Public Participation Documentation

- Attachment 1: Notice of public hearing and comment period

- Attachment 2: Attendees at the public hearing

- Attachment 3: Certification of public hearing

- Attachment 4: Hearing report, addressing all comments received

The enclosed materials meet the infrastructure requirements for the 2010 N02NAAQS.

However, if you need additional information to approve this SIP, please do not hesitate to

contact me.

We look forward to working with EPA as a critical partner in our continuing mission to

conserve, improve and protect the environment and public health for the citizens ofConnecticut.

Adequacy Determination of the Connecticut State Implementation Plan for

Clean Air Act Section 110(a) Infrastructure Elements:

2010 National Ambient Air Quality Standard for Nitrogen Dioxide (NO2)

On January 22, 2010, the U.S. Environmental Protection Agency (EPA) revised the primary national 

ambient air quality standard (NAAQS) for oxides of nitrogen, as measured by nitrogen dioxide 

(NO2). Specifically, EPA established a new 1-hour standard at a level of 100 parts per billion, based 

on the 3-year average of the 98th percentile of the yearly distribution of 1-hour daily maximum 

concentrations, to supplement the existing annual standard. EPA finalized initial designations in 

February 2012, assigning all of Connecticut as unclassifiable/attainment for the new NAAQS, based 

on available monitoring data from the 2008-2010 period. EPA‟s January 22, 2010 rulemaking also 

required Connecticut and other states to establish near-road monitoring networks to better assess NO2

levels near heavily traveled roadways. Connecticut expects to begin phase-in of its near-road 

monitoring network by early 2013.

Pursuant to Clean Air Act (CAA) Section 110(a)(l) and (2), all states are required to submit any 

necessary revisions to their State Implemenation Plans (SIP) to provide for the implementation, 

maintenance and enforcement of any revised or new NAAQS. States are required to maintain a 

comprehensive air quality management infrastructure, including enforceable emission limitations, an 

ambient monitoring program, an enforcement program, air quality modeling, and adequate personnel, 

resources, and legal authority. Section 110(a)(2)(D)(i) also requires each SIP to prohibit emissions 

from within the state that contribute significantly to nonattainment or maintenance areas in any other 

state, or which interfere with programs to prevent significant deterioration of air quality or to achieve 

reasonable progress toward the national visibility goal for Federal class I areas (national parks and 

wilderness areas). The infrastructure SIP revisions are due by January 22, 2013, three years after 

promulgation of the revised NO2 NAAQS.

The Connecticut Department of Energy and Environmental Protection (DEEP) hereby reviews its 

program infrastructure in relation to the revised 2010 NO2 NAAQS for each of the required CAA 

section 110(a)(2) infrastructure elements. Details of how Connecticut‟s SIP now satisfies or will, 

after revision, satisfy the infrastructure requirements are set out in Table 1 below.

Currently, DEEP is implementing the suggested significant impact levels and other Prevention of 

Significant Deterioration (PSD) requirements in EPA‟s June 29, 2010 “Guidance Concerning the 

Implementation of the 1-hour NO2 NAAQS for the Prevention of Significant Deterioration Program”. 

DEEP recognizes that EPA may, at some point in the future, establish a short-term PSD increment, 

significant impact level, significant emission rate, and/or significant monitoring level for the 2010 1-

hour NO2 NAAQS. If that occurs, DEEP commits to pursue adoption of appropriate regulatory 

revisions within a reasonable period following EPA‟s final adoption of required PSD program 

parameters

In addition, DEEP is drafting revisions to Section 22a-174-24 of the Regulations of Connecticut State 

Agencies (RCSA) to ensure consistency with the 2010 1-hour NO2 NAAQS, as well as other 

NAAQS recently revised by EPA. DEEP commits to pursue adoption of these regulatory revisions, 

with a goal of completion by September 30, 2013.

the State (or, except where the 

Administrator deems inappropriate, the 

general purpose local government or 

governments, or a regional agency 

designated by the State or general purpose 

local governments for such purpose) will 

have adequate personnel, funding, and

“shall (1) initiate and supervise programs for the purposes of determining the causes, 

effect and hazards of air pollution; (2) initiate and supervise state-wide programs of 

air pollution control education; (3) cooperate with and receive money from the 

federal government and, with the approval of the Governor, from any other public or 

private source; (4) adopt, amend, repeal and enforce regulations as provided in 

section 22a-174 and do any other act necessary to enforce the provisions of this

Environmental Protection will secure appropriations sufficient, in conjunction with 

federal assistance, to maintain the projected state funding levels.” 

CGS section 1-85 CAA section 128(a)(2) requires SIPs to contain adequate 

provisions requiring the DEEP commissioner to disclose any potential conflicts of 

interest. Connecticut has in place conflict of interest provisions that are broader than 

EPA‟s minimum requirements and that apply to all state employees and public

officials. These requirements, which are set out in section 1-85 of the Connecticut

General Statutes (CGS), prevent DEEP‟s commissioner from acting on a matter when 

a substantial conflict of interest exists. CGS section 1-85 is attached for approval by 

EPA as a part of this SIP revision.

The State of Connecticut is the sole authority implementing the SIP and does not rely 

on local or regional governments or agencies to carry out this responsibility.

Connecticut Statute Addressing Conflict of Interest

Inclusion in Revision of State Implementation Plan for Air Quality:

Infrastructure Requirements for the 2008 Ozone and 2010 NO2 NAAQS

Sec. 1-85. (Formerly Sec. 1-68). Interest in conflict with discharge of duties. A public official, including 

an elected state official, or state employee has an interest which is in substantial conflict with the proper 

discharge of his duties or employment in the public interest and of his responsibilities as prescribed in 

the laws of this state, if he has reason to believe or expect that he, his spouse, a dependent child, or a 

business with which he is associated will derive a direct monetary gain or suffer a direct monetary loss, 

as the case may be, by reason of his official activity. A public official, including an elected state official, 

or state employee does not have an interest which is in substantial conflict with the proper discharge of 

his duties in the public interest and of his responsibilities as prescribed by the laws of this state, if any 

benefit or detriment accrues to him, his spouse, a dependent child, or a business with which he, his 

spouse or such dependent child is associated as a member of a profession, occupation or group to no 

greater extent than any other member of such profession, occupation or group. A public official, 

including an elected state official or state employee who has a substantial conflict may not take official 

action on the matter.

HEARING REPORT

Prepared Pursuant to

Code of Federal Regulations Part 40, Section 52

Regarding Revisions to the

State Implementation Plan for Air Quality

Hearing Officer: Alison A. Rau

On November 19, 2012, the Commissioner of the Connecticut Department of Energy and 

Environmental Protection (DEEP) signed a notice of intent to amend the State Implementation 

Plan (SIP) for air quality to address the infrastructure requirements of Section 110(a)(1) and (2) 

of the federal Clean Air Act (CAA) with respect to the 2008 8-hour ozone and 2010 nitrogen 

dioxide (NO2) national ambient air quality standards (NAAQS). Pursuant to such notice, DEEP 

provided an opportunity for a public hearing and written comment. The public hearing was held 

at DEEP headquarters in Hartford, Connecticut on December 20, 2012. Written comments were 

accepted through the end of the public comment period on December 21, 2012.

I. Overview

This report describes the revisions to the SIP as proposed for hearing, the comments received 

through the comment period and DEEP’s responses. 

II. Summary of the Revisions as Proposed

The CAA requires states to submit SIP revisions to address the requirements of CAA section 

110(a)(1) and (2) within three years of promulgation of a revised NAAQS. The 8-hour ozone 

NAAQS were revised on March 27, 2008 and the NO2 NAAQS were revised on February 9, 

2010, resulting in the preparation and proposal of the subject SIP revision. The CAA section 

110(a)(1) and (2) requirements, which are referred to as infrastructure requirements, provide that 

a state must demonstrate its ability to implement, maintain and enforce revised NAAQS.

The proposed SIP revisions include tables of existing Connecticut and federal regulations that 

satisfy the CAA 110(a)(2) infrastructure requirements for both the ozone and NO2 NAAQS. 

DEEP concludes that the provisions of current regulations and the proposed adoptions currently 

in progress (described below) meet all of EPA’s required elements:

1. DEEP is implementing the suggested significant impact levels and other Prevention 

of Significant Deterioration (PSD) requirements in EPA’s June 29, 2010 “Guidance 

Concerning the Implementation of the 1-hour NO2 NAAQS for the Prevention of 

Significant Deterioration Program.” If in the future EPA establishes a short-term 

PSD increment, significant impact level, significant emission rate, and/or significant 

monitoring level for the 2010 1-hour NO2 NAAQS, DEEP commits to pursue such 
adoptions within a reasonable period following EPA’s final adoption of such required 

parameters. 

2. DEEP is pursuing revisions to RCSA 22a-174-24 to ensure consistency with the 2008 

ozone NAAQS, 2010 1-hour NO2 NAAQS and other recent EPA NAAQS revisions.

DEEP seeks to complete such regulatory revisions by September 30, 2013. 

3. DEEP is incorporating the existing statute, CGS section 1-85, to fulfill the 

requirements of 110(a)(2)(E).

III. Summary of Comments

The only comments received were from Anne Arnold, Manager, Air Quality Planning Group, 

EPA Region 1, Boston, Massachusetts, on December 20, 2012. The comments address four

subject areas:

1. Updating 2008 ozone and 2010 NO2 standards;

2. Addressing prongs 1 and 2 of portion D(i) at a later time;

3. Incorporating Connecticut statutes into the SIP; and

4. Referencing compliance assurance monitoring requirements.

A phone call was also received on December 3, 2012 from U.S. Army Regulatory Affairs 

Specialist Charlene Beairsto, who inquired about the meaning of and reference to section 1-85 in 

the SIP. 

All comments submitted are summarized below with DEEP's responses. 

1. EPA Comment: In order to receive full approval of its infrastructure State Implementation 

Plan (SIP) for the 2008 ozone and 2010 NO2 standards, Connecticut must update its Section 22a174-24 regulation to include the 2008 ozone and 2010 NO2 standards. We note that under 

Element A, the proposal states that Connecticut plans to complete this rulemaking by September 

2013. 

DEEP Response: DEEP plans to complete this rulemaking for the 2008 ozone and 2010 NO2

standards by the end of September 2013. 

2. EPA Comment: In light of ongoing litigation, we suggest Connecticut address the 

“significantly contribute to nonattainment or maintenance in another state” portion of element 

D(i), also sometimes referred to as prongs 1 and 2, at a later time. For the reasons explained in 

the November 19, 2012, EPA memorandum entitled “Next Steps for Pending Redesignation 

Requests and State Implementation Actions Affected by the Recent Court Decision Vacating the 

2011 Cross-State Air Pollution Rule,” at this time, EPA does not plan to make findings with 

respect to CAA section 110(a)(2)(D)(I), prongs 1 and 2. 

DEEP Response: As documented by EPA’s CSAPR modeling, Connecticut’s ability to attain 

the 2008 8-hour ozone NAAQS is substantially compromised due to the overwhelming influence 

of transported air pollution from upwind states. Monitoring data confirm the dominating role of 

transport, with measured values often exceeding the NAAQS at monitors located along the 
state’s most upwind boundaries, before any interaction with in-state emissions. Connecticut has 

done its fair share to reasonably control in-state emissions, and cannot continue to shoulder a 

disproportionate burden while upwind states fail to fulfill their CAA obligations. EPA’s CSAPR 

modeling supports that conclusion. CSAPR modeling projections for 2014 (a year before 

marginal areas are required to attain) indicate that Connecticut will no longer contribute 

significantly to out-of-state nonattainment issues in any area currently designated by EPA as 

nonattainment for the 2008 ozone NAAQS, with the exception of the NY/NJ/CT area. Rather 

than continuing to disadvantage Connecticut’s competitiveness and further the past inequity, 

DEEP will wait for EPA to address the CAA section 110(a)(2)(D) obligation of upwind states to 

assure the airshed wide control strategy focuses on the most cost effective and largest 

contributors.

EPA has a responsibility under the CAA to ensure that states meet the requirements of section 

110(a)(2)(D)(i)(I) in a timely fashion. EPA’s November 19, 2012 memorandum is not consistent 

with that responsibility and will result in additional delays in securing upwind reductions. EPA 

should instead issue findings of failure to submit for any state that has not addressed the transport 

provisions, thereby starting the two-year sanctions clock for imposition of a Federal 

Implementation Plan (FIP) that would mandate the necessary reductions and ensure continued 

progress toward attainment.

The technical support document should be revised to reflect the above discussion.

3. EPA Comment: The discussion for several elements includes reference to a number of state 

laws. Under element E, we note that Connecticut specifically requests that one of these laws

(CGS section 1-85) be incorporated into the SIP. Connecticut should ensure that when law(s) are 

the only program element(s) on which the state must rely to meet a specified CAA element, the 

law(s) are incorporated into the SIP. 

DEEP Response: DEEP has included CGS section 1-85 in this SIP revision to satisfy the 

conflict of interest requirements of CAA section 128(a)(2), as identified by CAA section 

110(a)(2)(E)(ii). DEEP understands that all the other Connecticut statutes used to satisfy 

program elements have been submitted to the SIP. If EPA believes that additional statutes are 

required, we invite EPA to get in touch with us so that we might address any gap.

4. EPA Comment: Although Connecticut references 22a-174-5 for meeting 110(a)(2)(F), the 

state should consider also referencing the compliance assurance monitoring requirements 

contained in section 22a-174-33 in meeting 110(a)(2)(F)(i). 

DEEP Response: Section 22a-174-33 implements the Title V operating permit program in 

Connecticut. DEEP understands Title V as standing outside the requirements of CAA sections 

110(a)(1) and (2), and as a result, DEEP has not proposed to include this rule in the Connecticut 

SIP. 
~Comment from U.S. Army Regulatory Affairs Specialist Charlene Beairsto: Called and

requested a citation and more information concerning section 1-85 in the SIP.

DEEP Response: DEEP provided Ms. Beairsto with full COS section 1-85 citation and

explained the conflict ofinterest provision via email.

IV. Conclusion

I recommend that the SIP revision as proposed, together with the above revisions made in

response to comments, be submitted to the EPA for approval.
