Permit name: State operating permit issued by DEQ, under the authority of the State Air Pollution Control Board.
Name, address and registration number: O-N Minerals (Chemstone) Company, 1696 Oranda Rd, Strasburg, VA 22657-3731, Registration No. 80252.
Description of proposal: The proposed revision is related to the control of emissions of particulate matter (PM), nitrogen oxides (NOX), and sulfur dioxide (SO2) to the atmosphere from O-N Minerals located in Shenandoah County, Virginia.
Virginia’s regional haze regulation is found in Article 52 (9VAC5-40-7550 et seq.) of 9VAC5-40, Existing Stationary Sources. This regulation provides guidance for determining Best Available Retrofit Technology (BART). BART is required for any BART-eligible source which emits any air pollutant which may reasonably be anticipated to cause or contribute to visibility impairment in any federal Class I area. BART is an emission limitation based on the degree of reduction achievable through application of the best system of continuous emission reduction for each visibility-impairing pollutant emitted by an existing stationary facility established on a case-by-case basis. O-N Minerals is subject to these requirements, has undergone a BART analysis resulting in the application of BART controls, and has obtained a state operating permit containing BART controls, which was submitted to EPA as a SIP revision on January 14, 2010.
The current proposed revision consists of a mutual and final determination between the source and DEQ, signed on May 4, 2010 that the one calcimatic kiln (U-l2) rated at 8.3 tons per hour of lime production is permanently shutdown. The state operating permit associated with this facility was then revised to reflect this change, and signed on August 6, 2010.
Federal information: This notice is being given to satisfy the public participation requirements of federal regulations (40 CFR 51.102). The proposal will be submitted as a revision to the Commonwealth of Virginia SIP under §110(a) of the federal Clean Air Act in accordance with 40 CFR 51.104.
How to comment: DEQ accepts written comments by email, fax, and postal mail.
