Public Notice: San Manuel Casino Draft Clean Air Act Synthetic Minor New Source Review (NSR) Permit in Indian Country

Publish Date: 04/30/2019


Proposed Action

The United States Environmental Protection Agency, Region 9 (EPA) provides notice of and requests public comment on the EPA’s proposed action relating to the revision to the synthetic minor New Source Review (NSR) permit for the San Manuel Casino (“Source”). The Source is located at 777 San Manuel Boulevard Highland, California 92346, within the San Manuel Reservation. The EPA is proposing to issue this modification of the existing synthetic minor NSR permit TA-0003-CA to the San Manuel Entertainment Authority (“Permittee”). The contact for the Source is Mike Hollingsworth, Facilities Director, 909-863-5899 x2454.

This draft permit, if finalized, will place enforceable restrictions on the Source’s potential to emit 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, as a modification to the existing Source, construction of 22 new and replacement emissions units: two new generators for a new 5-megawatt (MW) combined heat and power cogeneration system, six new cooling towers, a new emergency garage generator, 11 new water heaters, and two replacement Tier 4 emergency engines, consistent with the minor NSR regulations for Indian country (40 CFR 49.151-161). The Permittee is proposing to expand its existing casino operations as part of the Casino Expansion Project. This permit action will retain the existing synthetic minor limits at 9.87 ton per year (tpy) of NOx emissions and add additional synthetic minor limits on emissions of VOC and CO at 5.50 tpy and 10.63 tpy, respectively. More information on the emission changes and limitations associated with this draft permit can be found in Section 6 of the technical support document for this action.

The EPA will provide notice at least 30 days in advance of the date and time of any scheduled public hearing. The 30-day public comment period will be extended to the close of any public hearing on the San Manuel Casino.

Final Action

The EPA will send notice of our final permit decision to each person who submitted comments and contact information during the public comment period or requested notice of the final permit decision. The EPA will summarize the contents of all substantive comments and provide written responses in a document accompanying the EPA’s final permit decision. The EPA’s final permit decision will become effective 30 days after the service of notice of the decision unless:
  1. A later effective date is specified in the permit;
  2. The decision is appealed to the EPA’s Environmental Appeals Board pursuant to 40 CFR 49.159(d); or
  3. There are no comments requesting a change to the draft permit decision, in which case the final decision shall become effective immediately upon issuance.
