Re: Revision to New Hampshire State Implementation Plan to Meet the Requirements of the Clean 

Air Act, Section 110(a)(2) for the 2008 Ozone, 2010 Nitrogen Dioxide, and 2010 Sulfur Dioxide 

NAAQS 

Dear Mr. Conroy: 

In acknowledgement of the fact that EPA's September 13, 2013 1 guidance to states regarding i-SIPs 

does not require states to make SIP submittals to address the visibility provisions found at section 11 O(a)(2)(J) 

of the Clean Air Act, New Hampshire Department of Environmental Services (NHDES) requests withdrawal 

of the submittals made to address this aspect of 11 O(a)(2)(J) within the following infrastructure SIP 

submittals: 

I. 2008 ozone NAAQS submittal dated 12/3 1/20 12, wherein on page 11 of13 reference is made 

regarding visibility protection in several areas under the heading, "Subparagraph 11 O(a)(2)(J): PSD and 

Visibility Protection"; 

2. 2010 N02 NAAQS submittal dated 1/28/2013, wherein on page 10of12 reference is made 

regarding visibility protection in several areas under the heading, "Subparagraph 11 O(a)(2)(J): PSD and 

Visibility Protection"; and, 

3. 20 10 S02 NAAQS submittal dated 9/13/2013, wherein on page 13of45 reference is made 

regarding visibility protection in several areas under the heading, " Subparagraph 11 O(a)(2)(J): PSD and 

Visibility Protection". 

Attached are replacement pages for the above referenced submittals that have the reference to visibility 

provisions removed. 

If you have any questions regarding this submittal, please contact Felice Janelle at (603) 27 1-4848.

deterioration of air quality and visibility protection); ... " 

Applicable NH Laws and Regulations: 

• RSA 125:81 , XIV (recodified as RSA 125-C:6, XIV) authorizes the agency to establish and operate a 

statewide system under which permits shall be required for the construction and operation of new and 

modified stationary sources. 

• Env-A 619: Prevention of Significant Deterioration addresses PSD and visibility protection and is essential 

to meeting the requirements of 40 CFR 51.166 and 40 CFR 52.21. 

I Additional Information: 

Revisions to Env-A 619 (and Env-A 100: Organizational Rules) pertaining to the regulation of greenhouse 

gases were approved by EPA in a final rule published on February 6, 2012. (See 77 FR 5700.) Subsequent 

revisions to Env-A 619 were submitted as a SIP revision for EPA's approval on November 15, 2012 .

CAA Citation: 

"Each such plan shall. .. "provide for - (i) the performance of such air quality modeling as the Administrator 

may prescribe for the purpose of predicting the effect on ambient air quality of any emissions of any air 1 pollutant for which the Administrator has established a national ambient air quality standard, and (ii) the 

submission, upon request, of data related to such air quality modeling to the Administrator." 

Applicable NH Laws and Regulations: 

• RSA 125:81 (recodified as RSA 125-C:6) authorizes the department to exercise general supervision of the 

administration and enforcement of the statute and all rules adopted and orders promulgated under it; to 

develop a comprehensive program and provide services for the study, prevention, and abatement of air 

pollution; to conduct and encourage studies relating to air quality; to collect and disseminate the results of 

studies relating to air quality; to advise, consult, and cooperate with the cities and towns and other agencies 

of the state, federal government, interstate agencies, and other affected agencies or groups in matters 

relating to air quality; and, among other authorities, to exercise all incidental powers necessary to carry out 

the purposes of the statute . 

• Env-A 613.02: Denial of Permit Issuance authorizes NHDES to deny the issuance of a construction permit 

if modeling shows that a major source proposing to construct or make modifications in a nonattainment area 

will cause or contribute to a violation of the NAAQS for a pollutant for which that area is in attainment. 

• Env-A 619 .03: PSD Program Requirements incorporates by reference numerous paragraphs of 40 CFR 

52.21 , including (k)(l), (1), and (m), which require modeling by major sources prior to construction or major

Additional Information: 

N02 and other oxides of nitrogen (NOx) are chemical precursors to ground-level ozone and 

presumed precursors to fine particle formation. On days when ambient ozone or PM2.

concentrations are predicted to be high, NHDES exercises the authority granted under RSA 

125:81 (recodified as RSA 125-C:6) to issue public alerts. NHDES makes press releases and 

posts website notices advising people on how to help prevent air pollution and minimize the 

worst health effects of poor air quality. NHDES is one of the state partners in EPA's AIRNOW 

and Enviroflash Air Quality Alert programs. (See www.aimow.gov.)
