Dear Mr. Garvm:

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

pertaining to an amendment to the Allegheny County Health Department (ACHD) Rules and

Regulations, Article XXI, Air Pollution Control, relating to the revision by ACHD of an existing

regulation for fiberglass boat manufacturing materials. The revised regulation is contained in the

ACHD Rules and Regulations, Article XXI, Air Pollution Control, Section 2105.86, "Control of

VOC Emissions from Fiberglass Boat Manufacturing Materials." The regulation was revised to

include the previously omitted Table 2105.86, labeled, "Monomer VOC Content Limitations for

Open Molding Resin and Gel Coat Operations." This SIP revision is identified as a supplement

to revision 74 for ACHD's internal tracking.

On November 15, 2013, DEP submitted to EPA for approval a SIP revision for the ACHD

Fiberglass Boat Manufacturing Materials regulation and three other ACHD regulations

implementing Control Techniques Guidelines (CTGs). Upon review ofthe SIP revision, EPA

found that Table 2105.86 was missing from the Fiberglass Boat Manufacturing Materials

regulation. To address the situation, EPA offered a "conditional approval" ofthe SIP revision, if

ACHD committed to amending and DEP committed to submitting to EPA a revised

Section 2105.86 within one year ofthe publication ofthe conditional approval in the Federal

Register. After consideration, DEP requested in a letter (dated July 16, 2014) to EPA, the

conditional approval of ACHD SIP revision 74. EPA published the conditional approval ofthe

SIP revision in the Federal Register on November 26, 2014 (79 FR 70470). This supplemental

SIP revision satisfies the obligation to submit an amended Section 2105.86 to include the

previously omitted Table 2105.86.

The ACHD is a local health agency organized under Local Health Administration Law, Act 315

of August 24, 1951, P.L. 1304, as amended, whose powers and duties include the enforcement of

laws relating to public health within Allegheny County. The ACHD has an air pollution control

program that has been approved by DEP in accordance with Section 12 ofthe Air Pollution

Control Act.
