.34 ) An owner or operator conducting spray application equipment cleaning that meets or exceeds the applicability threshold ofsubdivision (2) ofthis subsection shall maintain daily records ofall cleaning solvents used, as follows: (i) Name and description ofeach cleaning solvent, (ii) VOCcontent ofeach cleaning solvent, as-applied, and the associated calculations

. As-applied VOCcontent shall be determined using an EPA reference method, a California Air Resources Board reference method or other method approved by the commissioner, (iii) VOCcontent ofeach cleaning solvent, as supplied, (iv) The amount ofeach cleaning solvent, (v) AMaterial Safety Data Sheet for each cleaning solvent, (vi) Adescription ofthe type ofcleaning equipment and process, (vii) Documentation ofcontrol device efficiency and capture efficiency, if applicable, using an applicable EPA reference method or alternate method as approved by the commissioner, and (viii) Date and type of maintenance performed on air pollution control equipment, if applicable

. (C) An owner or operator that is conducting spray application equipment cleaning subject to an exemption or exception in subdivision (3) of this subsection shall maintain records sufficient to verify the applicability ofthe exemption or exception

. Section 22a-174-32(b)(3) of the Regulations of Connecticut State Agencies is amended to read as follows: (3) When calculating potential emissions to determine the applicability of this section, the owner or operator of a premises shall include potential emissions ofvolatile organic compounds fromall sources located at such premises excluding those sources which are: (A) subject to regulation under 40 CFR [Parts] 61 and 63; ) required to use Best Available Control Technology or Lowest Achievable Emission Rate for VOCs pursuant to a federally enforceable order or permit which contains specific VOCemission limitations; (C) subject to regulation under 40CFR [Part] 264, Subparts AAor BB, or 40 CFR [Part] 265, Subparts AAor BB ; (D) fuel burning equipment; or35

(E) subjectto Reasonably Available Control Technology required pursuant to: (i) any one of the following subsections [(a), (b) or (1) through (y) inclusive] ofsection 22a-174-20 of the Regulations of Connecticut State Agencies[ ;]

- (a) (b) (Z) through (y) or (f) through (ji), (ii) section 22a-174-30 of the Regulations of Connecticut State Agencies[ ;] 1 or (iii) an order or permit requiring the implementation of Reasonably Available Control Technology issued by the commissioner prior to November 15, 1992 and approved by the Administrator priorto May 31, 1995

. Sec

. 9

. Section 22a-174-33(f)(6) of the Regulations of Connecticut State Agencies is amended to read as follows: (6) [Notwithstanding any other provision of this subsection, the owner or operator ofa Title Vsource subject to 40 CFR72 to 78, inclusive, which becomes subject to this section after January 1, 1998 shall submit a Title Vapplication to the commissioner within the time provided by 40 CFR72.30 or within ninety (90) days of receipt of notice fromthe commissioner that such application is required, whichever is earlier.] Reserved

. Statement of purpose: This amendment serves the primarypurpose of updating Connecticut's reasonably available control technology (RACT) requirements for volatile organic compounds (VOCs) in response to the U .S

. Envirornnental Protection Agency's issuance of control techniques guidelines (CTG) in 2006for 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, filmand foil ooating [72 FR57215]
. 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 formetal furniture and paper, filmand foil coating operations in section 22a-174-20 of the Regulations of Connecticut State Agencies (RCSA) are enhanced through the adoption of the CTGrequirements, which include lower VOC content requirements for coatings and work practices designed to reduce VOCemissions

. (Section 4) " New

requirements, consistent with the CTG, are added to RCSAsection 22a-174-20 for five source categories (flexible package printing; offset lithographic printing; letterpress printing; large appliance coating; general solvent cleaning)

. The requirements include VOCcontent limits for coatings, inks and solvents; an alternative compliance route through the operation ofair pollution control equipment; and work practices to limit VOCemissions fromcoating and solvent storage and handling

. (Section 7) " New requirements regulating the cleaning of spray application equipment to limit VOC emissions are added to RCSAsection 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 ofmore comprehensive requirements in RCSAsection 22a-174-41

. (Section 2)

### 36

. The amendment also updates internal references, exemptions and applicability determinations ofRCSA section 22a-174-20 with respect to additions made in the amendment; refines definitions; and updates the applicability deterrnination of RCSA section 22a-174-32 given the adoption ofthe new requirements

. (Sections 1, 3, 5, 6, 8) The VOCreductions associated with the RACTupdate 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 respectto Connecticut's compliance with the national fine particulate matter standards

. Section 9 of the amendment eliminates the reference to the federal Title Vapplication timelines for Acid Rain program sources fromRCSAsection 22a-174-33(f), as the federal timing requirements apply independently
