Dear Mr. Conroy: 

Enclosed for your review is New Hampshire's certification of adequacy ("infrastructure" SIP) for the 

2006 24-hour fine particulate matter smaller than 2 .5 microns in diameter (PM2.5) standard . 

Under sections 110(a)(1) and (2) of the Clean Air Act (Act), after promulgation of a new or revised 

National Ambient Air Quality Standard (NAAQS), each state is required to submit a plan to provide for 

the implementation, maintenance, and enforcement of the NAAQS . States are required to address basic 

state implementation plan (SIP) requirements, including emissions inventories, monitoring, and modeling 

to assure attainment and maintenance of the standards . By statute, SIPs for sections 110(a)(1) and (2) are 

to be submitted by states within 3 years after promulgation of a new or revised standard . EPA advises 

that Section I 10(a) infrastructure SIPs are due 3 years from the date of signature of the NAAQS, as this 

represents widespread dissemination and therefore promulgation of the NAAQS under 307(d) of the Act. 

For the 2006 24-hour PM2,5 standard, the due date is Sept 21, 2009. 

The New Hampshire State Implementation Plan was originally submitted to EPA on January 27, 1972, 

and has undergone numerous revisions since that date. New Hampshire's EPA-approved SIP, which is 

published in the Code of Federal Regulations at 40 CFR 52 Subpart EE, explicitly fulfills most of the 

requirements of sections 110(a) (1) and (2) . Other section I 10(a) (1) and (2) requirements are fulfilled in 

applicable chapters and parts from the New Hampshire Revised Statutes Annotated (RSA) pertaining to 

the duties and powers of the Commissioner of the Department of Environmental Services (NHDES) and 

in applicable chapters and parts from the New Hampshire Rules Governing the Control of Air Pollution, 

NH Administrative Rules Env-A 100 et seq. 

There are fourteen elements within sections I 10(a) (1) and (2) that New Hampshire is required to meet in 

the certification of adequacy. The specific statutes and administrative rules of the New Hampshire 

pro-ram that address those elements are identified in the attached table. Please note that New Hampshire 

is in the process of amending Part Env-A 303 Primary and Secondary Standards for Particulate Matter 

and will issue the revised rule following resolution of petition No. 06-1410, American Farm Bureau 

Federation and National Pork Producers Council v. Environmental Protection Agency, before the U .S . 

Court of Appeals for the District of Columbia Circuit . 

If you have any questions, please contact me at (603) 271-1088 or Charlie Martone of my staff at (603) 

271-1089 .
