On February 28, 2019, EPA provided notice of and requested public comment on EPA’s proposed action relating to the draft synthetic minor New Source Review (NSR) permit for the Cache Creek Casino Resort (“Source”). This draft permit, if finalized, will place enforceable restrictions on the potential to emit of the Source’s existing operations so that the provisions and requirements for major sources under the NSR and title V programs in 40 CFR parts 51, 52, and 71 do not apply. It will also authorize construction of three natural gas non-emergency generators, two diesel-fired emergency generators, and four boilers, consistent with the minor NSR regulations for Indian country (40 CFR 49.151-161). Cache Creek is a 415,000 square-foot gaming facility powered by the grid and four standby diesel engines. This permit action will establish the existing equipment at Cache Creek as an existing synthetic minor source at 24.19 ton per year (tpy) of NOx emissions and 6.72 tpy of CO emissions. The modification will increase NOx emissions by 14.68 tpy and CO emissions by 58.65 tpy. More information on the emission changes and limitations associated with this draft permit can be found in Section 5 of the technical support document for this action. Upon construction completion of the equipment, the Source will be a major stationary source as defined in Section II.A.4 of Appendix S to 40 CFR part 51.
The Administrative Record for this action can be accessed electronically through the online docket: EPA-R09-OAR-2018-0653, except for the following documents that are not compatible with the docket:
