NAME OF AGENCY 

Environmental Protection 

Statement of purpose: This amendment serves the primary purpose of updating Connecticut's 

reasonably available control technology (RACT) requirements for volatile organic compounds 

(VOCs) in response to the U.S . Environmental Protection Agency's issuance of control 

techniques guidelines (CTG) in 2006 for offset lithographic and letterpress printing, industrial 

cleaning solvents and flexible package printing [71 FR 58745] and in 2007 for metal furniture 

coating, large appliance coating and paper, film and foil coating [72 FR 57215]. The amendment 

also refines the requirements for metal cleaning ; adds requirements specific to spray application 

equipment cleaning ; and makes minor and technical revisions. 

Specifically : 

" The existing requirements for metal furniture and paper, film and foil coating operations 

in section 22a-174-20 of the Regulations of Connecticut State Agencies (RCSA) are 

enhanced through the adoption of the CTG requirements, which include lower VOC 

content requirements for coatings and work practices designed to reduce VOC emissions. 

(Section 4) 

" New requirements, consistent with the CTG, are added to RCSA section 22a-174-20 for 

five source categories (flexible package printing; offset lithographic printing; letterpress 

printing; large appliance coating; general solvent cleaning). The requirements include 

VOC content limits for coatings, inks and solvents ; an alternative compliance route 

through the operation of air pollution control equipment; and work practices to limit 

VOC emissions from coating and solvent storage and handling. (Section 7) 

" New requirements regulating the cleaning of spray application equipment to limit VOC 

emissions are added to RCSA section 22a-174-20 . (Section 7) 

" The reactivity-based architectural coating requirements of subsection (g) of RCSA 

section 22a-174-20 are deleted, given the adoption in July 2007 of more comprehensive 

requirements in RCSA section 22a-174-41 . (Section 2) 

" The amendment also updates internal references, exemptions and applicability 

determinations of RCSA section 22a-174-20 with respect to additions made in the 

amendment; refines definitions ; and updates the applicability determination of RCSA 

section 22a-174-32 given the adoption of the new requirements . (Sections 1, 3, 5, 6, 8) 

The VOC reductions associated with the RACT update portion of this amendment will assist 

Connecticut to attain the federal 8-hour ozone national ambient air quality standards and serve as 

directionally correct measures with respect to Connecticut's compliance with the national fine 

particulate matter standards. 

Section 9 of the amendment eliminates the reference to the federal Title V application timelines 

for Acid Rain program sources from RCSA section 22a-174-33(f), as the federal timing 

requirements apply independently.
