DearJ^KGarvnii

Enclosed for your approval is a revision to Pennsylvania's State Implementation Plan (SIP)

concerning an amendmentto 25 Pa. Code Chapter 129 (relating to standards for sources) for

implementationofreasonably available control technology (RACT) requirements for the control

of volatile organic compound (VOC) emissions from fiberglass boat manufacturingmaterials.

Recommendations of what constitutes RACT for the control of VOC emissions from these

materials are provided in the applicable control techniques guidelines issued by the United States

Environmental Protection Agency (EPA) in September 2008 (See Control Techniques

Guidelinesfor Fiberglass Boat Manufacturing Materials, EPA 453/R-08-004). The final

rulemaking adopting this regulatory amendment was effective upon publication in the

Pennsylvania Bulletin on December 19, 2015 (45 Pa. B. 7127).

The final rulemaking adds § 129.74 (relating to control ofVOC emissions from fiberglass boat

manufacturingmaterials) to adopt RACT requirementsand RACT emission limitations for

stationary sources ofVOC emissions from fiberglass boat manufacturing materials including

open molding resins, gel coats and cleaning materials. This final rulemaking also adds terms and

definitions to § 129.74 to support the interpretation ofthe measures. The requirements of

§ 129.74 supersedethe requirements of a RACT permit issued under §§ 129.91—129.95 (relating

to stationary sources ofNOx and VOCs) prior to December 19, 2015, to the owner or operator of

a source subject to § 129.74 to control, reduce or minimize VOCs from a fiberglass boat

manufacturing process, except to the extent the RACT permit contains more stringent

requirements.

Requirements for the control of VOC emissions from fiberglass boat manufacturing materials are

not currently set forth in Pennsylvania's SIP codified in 40 CFR Part 52, Subpart NN. The final

rulemaking Annex A sets forth new requirements to be approved and added to the SIP; the final

rulemaking does not make changes to existing approved SIP requirements.

This SIP revision submission includes one paper copy each ofthe final rulemaking notice, the

proposed rulemaking notice published in the Pennsylvania Bulletin at 44 Pa. B. 4502

(July 19, 2014), documentation ofthe public participation process including proof of public

notice and the proposed rulemaking notice, and the Department's public comment and response

document. This submission also includes one compact disc of electronic files that are exact

duplicates ofthe paper copy documents, including a copy ofthe signed transmittal letter.
