Title

Proposed Amended Rule 1171 - Solvent Cleaning Operations

Description

The proposed project would: 1) extend the Rule 1171 final compliance date to lower the volatile organic compound (VOC) content limit until January 1, 2010 for cleaning solvents used in ultraviolet or electron beam (UV/EB) ink application equipment; 2) extend the Rule 1171 exemption to comply with a lower VOC content limit until January 1, 2010 for: a) cleaing of UV/EB lamps and reflectors, b) cleaning of UV/EB ink application equipment (applicable only to metering rollers, dampening rollers, and printing plates), and c) on-press cleaning cleaning of screens subject to an interim limit of 300 grams per liter effective on date of adoption; and 3) permanently exempt cleaning products for photocurable resins from stereolithography equipment from complying with any VOC content limit in both Rules 1171 and 1122. the delay in emission reductions from extending the final compliance date and the emission reductions foregone from providing permanent exemptions would exceed the SCAQMD's daily VOC operational significance threshold, so the air quality impacts have been determined to be significant. Impacts to all other environmental topic areas were determined to be not significant.
