Collins Pine Co generation Facility in Chester, California Announcement of Proposed Permit, and Request for Public Comment on the Proposed Minor Revision to Clean Air Act Prevention of Significant Deterioration Permit

PSD Permit No. SAC 8 4

- 0 2 The United States Environmental Protection Agency, Region 9 (EPA) provides notice of, and requests public comment on, EPA’s proposed action relating to a minor modification of the Prevention of Significant Deterioration (PSD) permit for Collins Pine Cogene ration (CPC). EPA is proposing to issue a revision to CPC’s current PSD permit that would grant approval to CPC, in accordance with EPA’s PSD regulations (40 CFR 52.21) , to replace the existing wet electrostatic precipitator (ESP) control equipment with a new, dry electrostatic precipitator. ESPs are air pollution control equipment typically used to reduce particulate matter from exhaust streams. Use of an ESP is required by CPC’s current PSD permit , issued by EPA in 1984, and amended in 19 9 7 because EPA concluded that installation of an ESP constituted Best Available Control Technology (BACT). CPC’s existing wet ESP is used to reduce particulate matter emitted by Boiler No. 4 , which is a woodwaste

- fired cogeneration boiler rated at 242.3 MMBtu/hour

. Th e proposed dry ESP will also reduce particulate matter emitted by Boiler No. 4 but will use less water and allow for elimination of a wastewater stream. The proposed change s will result in minor emissions increases, but will not trigger any additional federal regulatory requirements pursuant to 40 CFR 52.21

. The requested modification will not alter BACT determinations or emission limits of the existing PSD permit. The mailing address for CPC is P.O. Box 796, Chester, California 96020. The location of the CPC facility is 13 Collins Drive , Chester, CA 96020.

EPA has the authority to issue PSD permits for facilities in Plumas County, California, which is under the jurisdiction of the Northern Sierra Air Quality Management District.

Any interested person may submit written comments on EPA’s proposed PSD permit for this modification. All written comments must be received or postmarked by April 30 , 2016. Comments should address the proposed permit revision. Comments must be sent or delivered in wr iting to Manny Aquitania at one of the following address es :
