Proposed General Plan Approval and General Operating Permit (BAQ-GPA/GP-10); Nonheatset Web Offset Lithographic Printing Press
[29 Pa.B. 1662] The Department of Environmental Protection (Department) proposes to issue general plan approvals and operating permits for nonheatset web offset lithographic printing presses (hereinafter referred to as the ''Nonheatset Web Press General Permit''). This general plan approval and operating permit, authorized under section 6.1(f) of the Air Pollution Control Act, applies only to plants that are not major volatile organic compound (VOC) or major hazardous air pollutant (HAP) emitting facilities.
The proposed general plan approval and general operating permit contains conditions that prescribe applicable performance standards, emission limits, monitoring, recordkeeping and reporting requirements for nonheatset web offset lithographic printing presses. The proposed general plan approval and operating permit may also be used to authorize the construction of new nonheatset web offset lithographic printing presses. Major facilities, as defined in 25 Pa. Code § 121.1 (relating to definitions), may use the general plan approval/general permit as a plan approval so long as major source permitting requirements are not triggered.
The proposed Nonheatset Web Press General Permit is the second air quality general plan approval/general permit prepared in consultation with the Graphic Arts Association and the Graphic Arts Technical Foundation. The Graphic Arts Technical Foundation has prepared guidance for the industry to determine if graphic arts facilities are subject to the permitting requirements, as well as, recordkeeping and reporting forms for showing compliance with the Nonheatset Web Press General Permit requirements.
Prior to operating under the Nonheatset Web Press General Permit, the owner or operator of the source must notify the Department and receive prior written approval from the Department before commencing to operate the affected facility. The owner or operator of an affected facility proposing to operate under this general permit shall notify the Department on a form provided by the Department and receive prior written approval to operate under the Nonheatset Web Press General Permit. The owner or operator of nonheatset web offset lithographic printing presses operating under this general permit must comply with the terms and conditions of the general plan approval and general operating permit.
Authorization to operate under the Nonheatset Web Press General Permit will be valid for a term of 5 years.
