EXECUTIVE SUMMARY

Tulsa County was designated a Flexible Attainment Region (FAR) for ozone in August 1995. This designation was achieved through the development of a plan to improve air quality in Tulsa County contained in a FAR Memorandum of Agreement (MOA). The MOA was signed by EPA, ODEQ, ODOT, ODPS, INCOG, Tulsa County, and various other entities. This document presents the 1995 base year Tulsa Special Emission Inventory for ozone in the Tulsa Management Area (TMA).

The inventory addresses volatile organic compound (VOC), oxides of nitrogen (NOx), and carbon monoxide (CO) emissions from stationary point, stationary area, on-road mobile, non-road mobile and biogenic sources. The Oklahoma Department of Environmental Quality, Air Quality Division, was the lead agency responsible for the compilation of the inventory. The area sources and a portion of the non-road mobile source inventory were completed by Enercon, Inc., a Tulsa-based contractor.

Total annual ozone precursor emissions and total average daily peak ozone season precursor emissions for the 1995 base year were determined for each source category. The description and documentation for each source category is provided. The tables below summarize the results of the inventory:

1. 0 BACKGROUND AND EMISSIONS SUMMARY

 

1.1 BACKGROUND

Tulsa County was designated a Flexible Attainment Region (FAR) for ozone in August 1995. This was achieved through the development of a FAR Memorandum of Agreement (MOA) providing a plan to improve air quality in Tulsa County. The MOA was signed by EPA, ODEQ, ODOT, ODPS, INCOG, Tulsa County, and various other entities. This document presents the 1995 base year Tulsa Special Emission Inventory for ozone in the Tulsa Management Area (TMA). The inventory addresses volatile organic compound (VOC), oxides of nitrogen (NOx), and carbon monoxide (CO) emissions from stationary point, stationary area, on-road mobile, and non-road mobile emission sources. Emissions of VOC and NOx are also addressed for biogenic sources.

The emissions inventory for the Tulsa Management Area covers the City of Tulsa and the area surrounding Tulsa County, extending 24 miles from the center of downtown Tulsa. In addition to Tulsa County, the area encompasses parts of Creek, Muskogee, Okmulgee, Osage, Pawnee, Rogers, Tulsa, Wagoner, and Washington Counties. A strict 24-mile boundary does not coincide with county or other jurisdictional lines. The area inside the 24-mile boundary was converted to a percentage for each county and used in calculations. The TMA is illustrated in Figure 1-1. A detailed map is provided in Appendix C of Section 3.0

The agency with the direct responsibility for preparing and submitting the Tulsa Special Emissions Inventory for the FAR is the Oklahoma Department of Environmental Quality (DEQ), Air Quality Division (AQD). The AQD was directly responsible for coordinating and supervising the completion of each segment of the inventory. Several other state and local agencies contributed information that was necessary for preparing emission estimates. For example, the Oklahoma Department of Transportation provided information on the total length and location of state highway projects to determine emissions from asphalt paving. The Oklahoma Corporation Commission provided information on the number of oil and gas wells in the TMA.

The AQD staff completed the emissions inventory for the stationary point, on-road mobile, biogenic, and the majority of the non-road mobile sources. The stationary area sources and a portion of the non-road mobile sources were completed by Enercon Services, Inc. who was contracted to complete these sections of the inventory. The contact persons for the major contributors to the inventory are listed in Table 1-1. The exact mechanisms by which each of these groups supported the development of the base year inventory are explained in detail in the appropriate source type documentation section.

 

1.2 EMISSIONS SUMMARY

Total annual ozone precursor emissions from the TMA for the 1995 base year are shown below:

VOC emissions = 53,246 tons/year

NOx emissions = 56,667 tons/year

CO emissions = 226,478 tons/year

Figure 1-2 illustrates the relative magnitude of the annual emissions in the TMA.

Total average daily peak ozone season precursor emissions from the TMA for the 1995 base year are shown below:

Daily emissions were averaged for the 3-month peak ozone season for the TMA, which was determined as June 1 to August 31 (based on the highest ozone violations for the years 1993-1995). Figure 1-3 illustrates the relative magnitude of daily emissions from different sources for the TMA.

Table 1-2 and Table 1-3 summarize annual and ozone season daily emissions, respectively, by county. Figure 1-4 illustrates the distribution of annual emissions by county. Table 1-4 and Table 1-5 summarizes annual and ozone season daily emissions, respectively, for the entire study area according to the five major source type categories: stationary point sources, stationary area sources, non-road mobile sources, on-road mobile sources, and biogenic sources. The percentage contribution of each of the source types to the total inventory emissions for VOC, NOx, and CO are as follows (see Figure 1-5):

VOC (%) NOx (%) CO(%)

Stationary Point Sources 6.3% 45.2% 2.2%

Stationary Area Sources 32.1% 7.4% 1.4%

On-Road Mobile Sources 46.1% 35.0% 79.3%

Non-Road Mobile Sources 15.6% 12.4% 17.1%

Table 1-6 through Table 1-8 summarize emissions for each pollutant for each individual county by major source type class.
