DEPARTMENT OF ENVIRONMENTAL PROTECTION 

Notice of Two Revisions to the State Implementation Plan for Air Quality: 

Visibility Protection and Reasonably Available Control Technology (RACT) 

The Commissioner of the Department of Environmental Protection (DEP) hereby gives notice of 

a public hearing as part of a proceeding to revise the State Implementation Plan (SIP) for air 

quality to : (1) address the visibility protection requirements of section 169A of the federal Clean 

Air Act (CAA); and (2) update RACT requirements, given the promulgation of eleven federal 

control techniques guidelines (CTGs) in 2006 through 2008. Both the visibility and RACT 

elements of this proposal will be submitted to the U.S . Environmental Protection Agency (EPA) 

for review and approval as a revision to the SIP. 

Visibility Protection 

The visibility protection SIP revision is a plan consistent with the national goal of restoring 

natural visibility conditions to mandatory Class I Federal Areas by 2064. The proposed SIP 

revision also satisfies the Regional Haze Rule (40 Code of Federal Regulations (CFR) 51 .300-

309), which seeks to protect mandatory Class I Federal Areas by addressing the combined 

visibility impacts of various air pollution sources over a large geographic region . 

The proposed plan includes an assessment of baseline and natural visibility conditions, an air 

monitoring strategy, an alternative program for Best Available Retrofit Technology, a set of 

reasonable progress visibility goals, and a long-term strategy for achieving those goals . 

RACT 

On February 1, 2008, DEP submitted to EPA an attainment demonstration for the 1997 8-hour 

ozone national ambient air quality standard . That attainment demonstration includes an analysis 

of how Connecticut complies with the RACT requirements of the CAA. EPA's adoption of 

eleven CTGs in 2006 through 2008 requires that DEP update its RACT analysis. In the proposed 

SIP revision, DEP makes negative declarations for three CTG source categories (flat wood 

paneling coating, fiberglass boat manufacturing, automobile and light-duty truck assembly 

coating) ; provides a statement of equivalency for one CTG (miscellaneous industrial adhesives); 

and indicates the status of pending DEP regulatory revisions for the seven remaining CTGs 

(industrial cleaning solvents ; offset lithographic printing and letterpress printing; flexible 

package printing; paper, film and foil coating; large appliance coating; metal furniture coating; 

miscellaneous metal and plastic parts coating) . 

All interested persons are invited to comment. Comments should be submitted to DEP, Bureau 

of Air Management, Engineering & Enforcement Division, 79 Elm Street, Hartford, Connecticut 

06106-5127 . All comments should be directed to the attention of Merrily Gere and must be 

received by 4:30 PM on August 28, 2009. Comments may be submitted by post, facsimile to 

(860) 424-4064 or by electronic mail to merrily. g-ere-&ct. og-v . 

In addition to accepting written comments, DEP will also hold the public hearing described 

below. Any person speaking at the hearing is requested to submit a written copy of his or her
