SECTION I. INTRODUCTION

The Southeast Oklahoma City Landfill (Southeast) is an active municipal solid waste landfill for non-hazardous solid waste (SIC 4953) and asbestos containing wastes. The landfill began receiving refuse in 1965 and has a design capacity of 11,375,151 megagrams (Mg) of refuse. The facility is owned and operated by Oklahoma City Landfill, LLC. The facility was issued Title V Permit No. 99-401-TV on May 29, 2001. On August 22, 2002, the facility submitted an application for the installation of a soil vapor vent/flare. On December 17, 2002, the facility submitted a Tier 2 Non-methane Organic Compound (NMOC) Emission Rate Report to ODEQ. The report indicated that the 2002 NMOC emission rate was above the NSPS applicability threshold of 50 megagrams per year (Mg/yr). As a result, the facility submitted a Gas Collection and Control System (GCCS) Design Plan on December 12, 2003. The facility is currently operating under Permit No. 99-401-TV (M-1) which incorporated the GCCS into its Title V permit.

SECTION II. FACILITY DESCRIPTION

Southeast currently operates an active GCCS in the landfill. The GCCS conveys the extracted landfill gas (LFG) to an existing LFG processing/flare facility owned and operated by Oklahoma Gas Producers, LLC (OGP) which is owned by DTE Biomass Energy Services (DTE). The facility also has a soil vapor extraction system that collects vapor from soils and conveys it to a vent/flare to be combusted or directly vented to the atmosphere.

OGP owns the rights to extract the LFG from the facility and processes the majority of the extracted LFG to be sold as medium-Btu fuel to an offsite consumer. The remaining extracted LFG is diverted to the utility vent/flare.

SECTION III. EMISSIONS

The facility includes the following emission sources:

·  MSW Landfill – fugitive emissions from the decomposition of organic materials,

·  Vent/Flare – emissions generated from the combustion of soil vapors,

·  Earthmoving Equipment Operations – fugitive particulate emissions generated from landfill earthmoving equipment operations.

1. Uncontrolled NMOC emissions for the landfill (with no GCCS) were estimated using EPA’s Landfill Gas Emissions Model and calculated to be 73.26 Mg/year (80.77 TPY) in the year of closing, 2017.

2. The emission estimates for the vent/flare were based on a worst-case scenario where the maximum soil vapor flow rate to the vent/flare is 500 scfm. The concentration for Nitrogen Oxides (NOx), Sulfur Dioxide, (SO2), Hazardous Air Pollutants (HAPs), Carbon Monoxide (CO) and Particulates (PM10) are based on the Environmental Protection Agency's (EPA's) Compilation of Air Pollutant Emission Factors, AP-42, 11/98 for MSW landfills.

3. The concentration for Volatile Organic Compounds (VOCs) is based on site-specific sampling from the landfill and AP-42, 11/98 standards.

4. The vent/flare destruction efficiency of VOCs and all HAPs, except Hydrogen Chloride (HCl), is 98%. This destruction efficiency estimate is widely accepted within the industry for vent/flares similar to the one installed.

5. Estimates of HAP emissions are based on LFG constituent concentrations in AP-42, 11/98.

6. Estimates of emissions from earth moving equipment operation are based on EPA’s Compilation of Air Pollutant Emission Factors (AP-42) Chapters 11 and 13.

Part 5 was a state-only requirement governing sources of toxic air contaminants that have emissions exceeding a de minimis level. However, Part 5 of Subchapter 41 has been superseded by OAC 252:100-42, effective June 15, 2006.

OAC 252:100-42 (Toxic Air Contaminants (TAC)) [Applicable]

Part 5 of OAC 252:100-41 was superseded by this subchapter. Any work practice, material substitution, or control equipment required by the Department prior to June 11, 2004, to control a TAC, shall be retained unless a modification is approved by the Director. Since no Area of Concern (AOC) has been designated anywhere in the state, there are no specific requirements for this facility at this time.

OAC 252:100-43 (Testing, Monitoring, and Recordkeeping) [Applicable]

This subchapter provides general requirements for testing, monitoring and recordkeeping and applies to any testing, monitoring or recordkeeping activity conducted at any stationary source. To determine compliance with emissions limitations or standards, the Air Quality Director may require the owner or operator of any source in the state of Oklahoma to install, maintain and operate monitoring equipment or to conduct tests, including stack tests, of the air contaminant source. All required testing must be conducted by methods approved by the Air Quality Director and under the direction of qualified personnel. A notice of intent-to-test and a testing protocol shall be submitted to Air Quality at least 30 days prior to any EPA Reference Method stack tests. Emissions and other data to demonstrate compliance with any federal or state emission limit or standard, or any requirement set forth in a valid permit shall be recorded, maintained, and submitted as required by this subchapter, an applicable rule, or permit requirement. Data from any required testing or monitoring not conducted in accordance with the provisions of this subchapter shall be considered invalid. Nothing shall preclude the use, including the exclusive use, of any credible evidence or information relevant to whether a source would have been in compliance with applicable requirements if the appropriate performance or compliance test or procedure had been performed.
