The Sac & Fox Tribe of the Mississippi in Iowa owns and operates the Meskwaki Bingo Casino Hotel (MBCH).  

The MBCH facility includes the operation of six diesel-fired engine-generators (also referred to as RICE(s), Reciprocating Internal Combustion Engines) and one natural gas fired backup generator. Four of the diesel-fired RICE  are non-emergency RICE used for peak load management, storm avoidance, and emergency backup power. Two diesel fired RICE  are used as backup units only. This synthetic minor source permit previously incorporated the replacement of an existing non-emergency RICE with a new non-emergency RICE manufactured and installed in 2019. The new RICE was certified by the manufacturer to meet EPA Tier 4 emissions requirements.

 Additionally, MBCH has several storage tanks 

for fuel, several natural gas combustion units (NGCUs) consisting of boilers, furnaces, water heaters used for space heating and water heating at the hotel/casino, collections of units associated with the cooking 

units, and four (4) induced draft cooling towers that provide comfort cooling for the MBCH buildings.

Air pollutants emitted from this facility's operations include nitrogen oxides (NOx), carbon monoxide (CO), sulfur oxides (SOx), volatile organic compounds (VOC), particulate matter (PM), PM with aerodynamic diameter equal to or less than 10 microns (PM10), PM with aerodynamic diameter equal to or less than 2.5 microns (PM2.5), hazardous air pollutants (HAP), and greenhouse gases (GHG).  The uncontrolled potential emissions of NOx are above the major source thresholds established under the Prevention of Significant Deterioration (PSD) permitting program regulations and the federal operating permit program regulations at 40 CFR Part 71 (Title V or Part 71).

A synthetic minor source permit was issued on September 10, 2019 under the authority of the Tribal Minor New Source Review Permit Program at 40 CFR Part 49 (TMNSR), (Permit Number R7-TMNSR-2019-002).  Under 40 CFR 49.158, a synthetic minor source permit may be obtained under this program to establish a synthetic minor source for nonattainment major New Source Review (NSR), PSD and Title V purposes and/or a synthetic minor HAP source for CAA standards established for maximum achievable control technology (MACT) and Title V purposes.

 Hence, the 2019 permit established federally enforceable nitrogen oxide (NOx) emission limitations for RICE-generators and several NGCUs operating at the facility to avoid PSD and/or Title V permitting requirements for major sources in 40 CFR parts 51 and 71 by limiting and monitoring the hours of operation and fuel usage of those emission units.  Table (B)(2) and Technical Support Document (TSD) of this permit contains the list of all NGCUs located at the site.


In 2020 and 2022 MBCH submitted permit applications to incorporate two new projects  -  laundry dryer and HVAC/heating replacement  -  into the synthetic minor source permit. The PTE for both projects by themselves were below the minor source thresholds (Table 1 of 40 CFR Part 49.153). However, a modification of the synthetic minor source permit was needed to revise the compliance formula. In addition, revisions are also being made to make some requirements more robust and relevant with the new project scope. Thus, this current permitting action incorporates these changes at the facility into the synthetic minor permit issued in 2019 to MBCH.

The MBCH facility is currently under contract to serve as a peaking power plant throughout the year and must be available to operate upon demand. Regardless of the extent that such contract (or another similar contract in the future) affects the MBCH operations, the facility is required to comply with the conditions of this permit unless and until the permit is modified.

- GENERAL PERMIT REQUIREMENTS


Definitions

Terms and conditions in this permit have the meaning assigned to them in 40 CFR 49.152 unless other regulations or statutes are referenced or applicable.

Issuance and Effective Date of Permit

EPA is issuing this permit pursuant to the Federal Minor New Source Review Program in Indian Country, 40 CFR 49.151-49.161.

The Effective Date is specified on the first page of this permit.

Construction without a Permit

If the permittee constructs or operates any source or modification not in accordance with the terms of any approval to construct, the permittee shall be subject to appropriate enforcement action.

Construction Approval

Nothing in this permit shall alter the requirement for the permittee to obtain a construction permit prior to beginning construction or modification of an emission unit.

Approval for construction or installation shall not relieve the permittee of the responsibility to comply fully with applicable provisions of any other requirements of federal law or regulation, including Title V of the CAA.

Modifications to Existing Permitted Emissions Units/Limits

For proposed modifications, as defined at 40 CFR 49.152(d), that would increase an emissions unit's allowable emissions of pollutants above its existing permitted annual allowable emissions limit, the permittee shall first obtain a permit modification pursuant to the TMNSR regulations approving the increase. For a proposed modification that is not otherwise subject to review under the PSD or TMNSR regulations, such proposed increase in the annual allowable emissions limit shall be approved through an administrative permit revision as provided at 40 CFR 49.159(f).

Compliance with Permit Requirements

The permittee shall comply with each term and condition in this permit.  Failure to comply with any term or condition of this permit constitutes a violation of the permit, and may constitute a violation of the CAA and serve as grounds for:

An enforcement action under Section 113 of the CAA; or

Termination, revocation and reissuance, or modification of this synthetic minor permit.

This permit currently requires monthly calculations of emissions.  Should EPA determine that calculated emissions are approaching or exceeding an emission limit, or should EPA determine that the permittee is failing to maintain adequate monitoring and recordkeeping requirements, EPA may revise, reopen or modify the permit to require daily calculations of emissions and/or require additional control technologies and emission reduction measures.  A revision that requires more frequent reporting of daily calculations of emissions is an administrative permit revision under the TMNSR program, 40 CFR 149.159(f) (2).

It is not a defense in an enforcement action for violation of this permit that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this permit.

Compliance with the terms of this permit does not relieve or exempt the permittee from compliance with other applicable Clean Air Act requirements or other applicable federal requirements, tribal, state or local laws or regulations.

National Ambient Air Quality Standards (NAAQS) / Prevention of Deterioration (PSD) Protection

The permitted source must not cause or contribute to a NAAQS violation or, in an attainment area, must not cause or contribute to a PSD increment violation.
