The point source data was obtained from the files of the Air Quality Section of the Utah State Division of Health. Data for about 80 sources was recorded on NEDS point source forms. Sources with the potential to emit over 25 tons/year of any of the five major pollutants, (particulates, sulfur dioxide, nitrogen oxides, hydrocarbons, and carbon monoxide) were included. The Air Quality Section of the Utah State Division of Health completed the NEDS area source forms during August 1973. GCA evaluated the methods used and thoroughly checked the area source forms. In order to present the geographical distribution of emissions in the area of the highest emissions, a grid system for the Davis, Salt Lake, Utah, and Weber County areas was developed by GCA. The grid consisted of 312 squares ranging in size from 400 km2 to L57 km2. Emissions from all sources were calculated for each grid. ------- SECTION II SUMMARY OF POINT AND AREA SOURCES The results of the emission inventory are summarized in tables 1 and 2. Table 1 summarizes the data by Air Quality Control Region and source type. Table 2 summarizes the data by county and source type. Figure 1 is a map of Utah, the Air Quality Control Regions, and the counties. A general discus- sion of the results for each of the five pollutants is presented in the fol- lowing sections. A. Particulates 1. Statewide, 36% of the calculated particulate emissions were from area sources. Combustion of coal by industry was responsible for over half of the area source parti- culate emissions. Point sources accounted for 64% of the particulate emissions. About one-third of the point source emissions were from coal combustion. 2. The particulate emissions rates from the three AQCR's were quite different. Only 3% of the total particulate emissions in Utah occurred in the Four Corners Interstate AQCR. Particulate emissions in the small Wasatch Front Intrastate AQCR accounted for 67% of the particulate emissions in Utah. B. Sulfur Dioxide 1. Area sources accounted for only 9% of the sulfur dioxide emissions in Utah. Industrial combustion of distillate oil, residual oil and coal was the primary area source of sul- fur dioxide. A copper smelting operation in the Wasatch Front AQCR was responsible for 65% of the sulfur dioxide emitted in Utah. The remainder of the point source sulfur dioxide emissions was caused by fuel burning. 2. Sulfur dioxide emissions from the Wasatch Front AQCR were 92% of the state total. Point sources in the Wasatch Front AQCR accounted for 85% of the sulfur dioxide emitted in Utah. C. Nitrogen Oxides 1. Area sources account for 77% of the nitrogen oxides emission in Utah. On and off highway fuel use accounts for over half the nitrogen oxide emissions. Point source emissions of nitrogen oxides are caused by fuel burning operations. The ------- largest point sources are petroleum refining and metal- lurgical industries. 2. The Wasatch Front Interstate AQCR accounts for 68% of the nitrogen oxide emissions in Utah. D. Hydrocarbons 1. Area sources account for 92% of the hydrocarbon emissions. Over 60% of the hydrocarbon emissions are from transpor- tation sources. Evaporative sources account for about 8% of the hydrocarbon emissions. Petroleum refining and the metallurgical industry are the primary hydrocarbon point sources. 2. The Wasatch Front AQCR accounts for 64% of the hydrocarbon emissions in Utah. Point sources in the Wasatch Front AQCR account for 99% of the point source hydrocarbon emis- sions in Utah. E. Carbon Monoxide 1. Area sources account for 97% of the carbon monoxide emis- sions. About 90% of the carbon monoxide emissions are from transportation sources. Point source emissions occur pri- marily from petroleum refining and the metallurgical industry with significant emissions also occurring from solid waste disposal and large fuel burning sources. Petroleum refineries and large metallurgical operations have carbon monoxide controls. 2. The Wasatch Front AQCR accounts for 65% of the carbon monoxide emissions in Utah. ------- SECTION III SUMMARY OF GRID RESULTS The study area for this grid system consisted of Davis, Salt Lake, Utah and Weber counties in the Wasatch Front Intrastate AQCR. The only county in the Wasatch Front AQCR not included in the grid system was Tooele county. The grid system, using UTM coordinates, consisted of 312 square grids rang- 9 £ 9 ing in size from 400 km • to 1.57 km . The smaller grids were located in the more densely populated areas. Figures 2-8 are maps of the grid system. Figure 2 is an overall map, while Figures 3-8 are maps of inset areas. The emission density maps, Figures 10-14, and Table 3 summarize the _3 results of the grid system study. Table 3 listing the emission rates (10 tons/day) for the overall area and each inset area shows that the majority of the emissions occur in the inset areas. Table 3 shows that 67% of the particulates, 27% of the sulfur dioxide, 59% of the nitrogen oxides, 78% of the hydrocarbons and 76% of the carbon monoxide emissions occur in the inset _3 areas. Figures 10-14 show the much higher emission densities (10 ton/day- 2 mi ) that occur in the densely populated inset areas. Emissions for each grid were calculated by a computer program. For each grid, Table 4 lists the area (square miles) and the emission density for each of the five major pollutants. Additional data including a table for each grid, listing emission densities for each pollutant and source type has been calculated and is available. The following source types are included in the above table: Point Sources Area Sources Residential Bituminous Coal •Distillate Oil Natural Gas Commercial-Institutional Bituminous Coal Distillate Oil Residual Oil Natural Gas ------- industrial Diesel Fuel Evaporation Incineration Bituminous Coal Distillate Oil Residual Oil Natural Gas Off Highway Railroads Solvent Gasoline Industrial Commercial Limited Access Roads Rural Roads Light Vehicles Heavy Vehicles Heavy Vehicles - Diesel Light Vehicles Heavy Vehicles Heavy Vehicles - Diesel Urban Roads Light Vehicles Heavy Vehicles Heavy Vehicles - Diesel Off Highway - Gasoline Airports Emissions from sources not Included in the above list are not significant or unknown. ------- SECTION IV POINT SOURCE METHODOLOGY The purpose of the point source emission inventory was to complete NEDS point source forms on all sources emitting over 25 tons/year (before control equipment) of any of the five major pollutants. The Air Quality Section of the Utah State Division of Health conducted the point source data collection. Information on approximately 80 plants was furnished to GCA. It was necessary to use 1970 data for about 6 sources as no new data had been collected. GCA designed a mailing list of potential sources in an effort to be sure that .all sources had been located. The mailing list was inspected by personnel of the Air Quality Section and they determined that it contained no additional sources. NEDS point source forms were completed for the following types of sources: solid waste disposal facilities, electric power generation plants, feed and grain elevators, phosphate fertilizer manufacturers, nitrate fertilizer manufacturers, copper smelting, iron and steel mills, gray iron foundries, secondary lead smelters, brick and clay products, portland cement manufac- turers, clay sintering plants, coal drying plants, concrete batch plants, lime manufacturing plants, gypsum manufacturing plants, asphalt concrete plants, perlite manufacturing plants, phosphate rock processing plants, sand and gravel processing plants, stone quarrys, petroleum refineries and various establishments with boilers. The largest individual sources were copper smelters, steel plants, petroleum refineries and electric power plants. NEDS point source forms were completed according to the directions in "Guide for Compiling a Comprehensive Emission Inventory" About 200 point I.D.*s were completed for the 80 plants included in this inventory. Whenever possible, plant data was broken down into individual source data and entered on separate point I.D. forms. UTM coordinates to the nearest one-tenth of a kilometer were generally available from Utah personnel. When necessary, GCA used 1/24,000 scale U.S.G.S. maps to obtain the UTM coordinates. Stack data when available was recorded. Pollution control efficiencies reported by sources were almost always used. In cases where the pollution control ------- efficiency was unreasonable or not given, the efficiency was estimated from 2 3 data in AP42-1 and AP42-2 . Emission data from stack sampling was avail- able from some sources and was always used. For sources not reporting emissions, the emissions were calculated from data in AP42-2. Utah air pol- lution control regulations were used to calculate allowable particulate emissions for sources not located in the Wasatch Front Intrast,ate AQCR and to calculate allowable sulfur dioxide emissions regardless of location. Allowable particulate emissions for sources located in the Wasatch Front 4 Intrastate AQCR were calculated according to new regulations issued by the EPA in May 1973. When the sulfur or ash content of a fuel was unavailable it was assumed to be equal to the area source sulfur or ash content as reported by Utah personnel. ------- SECTION V AREA SOURCE METHODOLOGY The NEDS area source forms were completed by the Air Quality Section of the Utah State Division of Health. The methods used generally followed chapter 5 of APTD 1135 and are outlined below. . A. Emission Estimates Emission estimates were calculated from emission factors found in AP42-12. Aircraft emissions, were calculated from data on LTO's, type of aircraft and number of engines per plane. B. Residential Fuel Residential use of bituminous coal, distillate oil and wood was calculated from census data on the number of dwelling units using each fuel in each county5, the average number of rooms per dwelling unit in Utah,5 degree day data and the fuel consumption factors in APTD 1135. Natural gas use was obtained from dealers. C. Commercial - Institutional Fuel Commercial-institutional bituminous coal, distillate oil and residual oil use was determined from the latest Bureau of Mines data.6,7 when necessary, the residential and point source commercial-institutional fuel use was subtracted from the Bureau of Mines data before apportioning to counties. „ The above fuel use was apportioned to counties by population. Commercial-institutional natural gas used by county was obtained by contacting natural gas dealers. D. Industrial Fuel Industrial bituminous coal, distillate oil and residual oil use was obtained from the latest Bureau of Mines data.6>7 After subtracting industrial point source fuel usage the remaining fuel use was apportioned to counties by manufactur- ing employees.^ Industrial natural gas usage was determined by contacting natural gas dealers. E. On Site Incineration and Open Burning On site incineration and open burning estimates were deter- mined from the national per capita averages as indicated in APTD 1135*. County and urban population was obtained from the 1970 census.^ Open burning by industrial and commercial- institutional sources is prohibited in Utah so zeroes, were 8 ------- entered in the appropriate spaces. Residential open burn- ing is prohibited in Davis, Salt Lake, Utah and Weber counties so zeroes were entered for open burning in those counties. F. Gasoline Fuel Data in "Vehicle Miles on Utah Highways 1972"9 and an 1Q additional table published by the Utah Highway Department was used to determine gasoline fuel used and measured vehicle miles. The first publication contains VMT data by county and vehicle type but only includes state or federally aided roads. The second publication includes all roads but only VMT data by road type for the whole state. Local rural roads, not state or federally aided, account for 17% of the rural VMT so the county VMT data in the first publication was increased by 17% to include these roads. Similarly, county VMT data for urban areas was increased by 30% in order to include local urban or municipal roads. Heavy vehicle gasoline usage was determined by subtracting the state diesel VMT from the state heavy vehicle VMT and then dividing by an average fuel consumption of 8.4 miles per gallon. The state heavy vehicle gasoline was apportioned to counties by heavy vehicle VMT data. Light vehicle gasoline was determined by subtracting the heavy vehicle gasoline from the total taxed gasoline and then adding the gasoline used by government vehicles. Light vehicle gasoline use was apportioned to counties by VMT data. Off highway gasoline consumption was calculated from the factors of 1000 gallons/tractor-year and 13 gallons/person . as specified in APTD 11351. Data on tractors in Utah was obtained from the "Census of Agriculture". Off highway gasoline was distributed to counties by population. G. Diesel Fuel On highway heavy vehicle diesel fuel consumption was obtained from the Utah State Tax Commission. Heavy vehicle diesel fuel was apportioned to counties by county heavy vehicle VMT data. Off highway diesel fuel was calculated by using the factors of 1000 gallon/tractor year, 5000 gallons/year per non- building construction employee and 7.4 galIons/person as specified in APTD 1135. In addition, it was known that a large open pit mining operation in Salt Lake county uses 7,000,000 gallons/year or 1000 galIons/employee. Therefore, an additional factor of 1000 gallon/mining employee was used. ------- Diesel fuel use for mining was only a small part of the total off highway diesel fuel use in all counties except Salt Lake County. County off highway diesel fuel consump- tion was calculated directly from each of the above factors. Diesel fuel usage by railroads was obtained by contacting railroad companies. . H. Aircraft Aircraft LTO cycles were determined from a study done by a university in Utah. Also military airfields were contacted. I. Vessels Fuel use by vessels was expected to be a very small source of air pollution in Utah, so it was assumed to be zero. J. Evaporation Solvent purchased was determined from the factor of 2.7 pounds per person per year for dry cleaning and the additional factors for surface coating and degreesing as listed in Table 5.2 in APTD 1135.l Gasoline marketed was calculated by summing the previously calculated gasoline use. K. Measured Vehicle Miles The data in Vehicle Miles on Utah Highways was adjusted as previously discussed in the section on gasoline fuel and was used as measured vehicle miles. Limited access road VMT was obtained from VMT on interstate highways. Rural road VMT were obtained from the rural category. The suburban and urban VMT total were assumed to equal the urban category in Vehicle Miles on Utah Highways. The suburban and urban road VMT were estimated by separating the inner city travel and the travel on the fringes of the city. L. Miscellaneous Sources 1. Dirt road vehicle miles traveled was estimated from data on the type of road, length of road and the average number of vehicles/week for each type of road. Each county was done separately by maps. 2. Dirt air strip data was obtained from the Utah Aeronautics Commission. 10 ------- 3. Construction land area was assumed to be the area likely to be damaged by wind as reported on U.S. Soil and Conservation maps. 4. Rock handling and storage data was obtained from replies to questionnaires by sources that were too small to be point sources. 5. Forest fire and stack burning data by county was obtained from the state forest service. 6. Frost control in Utah is very small and was assumed to be zero. 7. Structure fires were calculated by using the factor of 4 fires/1000 people as specified in APTD 1135.* 8. There is no coal refuse burning in Utah. GCA reviewed all area source categories. However, the emission estimates were not re-calculated. The total off highway diesel fuel use exceeded the published Bureau of Mines total by 82%; Off highway diesel fuel use cal- culated for mining was only a small contribution to all counties except Salt Lake where it is known to be accurate. Therefore, the numbers were not changed. Methods used to estimate suburban VMT may not have been accurate and the data entered in NEDS forms should really be measured vehicle miles travelled. No revisions on the NEDS area source forms were made by GCA. However, when the data was used for the grid system, suburban and urban VMT were combined and treated as urban. 11 ------- SECTION VI GRID SYSTEM METHODOLOGY The purpose and results of the grid system study have been previously described in section III. The purpose of this section is to describe the methods used to design the system and calculate the emissions. Since the grid data will be used in meteorological dispersion models, all grids must be square. Higher emissions usually occur in more densely populated areas, so to better present the distribution of emissions, smaller grids were drawn in those areas. Maps showing the grid system are presented in Figure 2-8. The population in each grid was determined from 1970 census tract 12,13,14 maps. » »• Figure 9 shows some of the census track that were used to determine the population of the grid in Figure 8. NEDS area source data, completed in August 1973 by the Air Quality Section of .the Utah State Division of Health was used extensively. Individual county totals for residential, commercial-institutional and industrial fuel use was apportioned to grids in the county by population. County totals for on site incineration, solvent purchased, and gasoline marketed were also apportioned to grids by population. Off highway diesel fuel and gasoline were apportioned to grids by area. However, before apportioning off highway diesel fuel, the 7,000,000 gallons used at the large open pit copper mine in Salt Lake county were assigned to the appropriate grid as a point source. Data was obtained from the Air Quality Section of the Utah State Division of Health on diesel fuel usage by railroads. The data included the amounts used in each-county in both railroad yards and on open tracks. The diesel fuel used in each county in railroad yards was apportioned to grids by the relative size of the railroad yards on 1/24,000 scale U.S.G.S. maps. Diesel fuel used on open tracks was apportioned to grids by track miles. Airport LTO cycles for each of the 9 airports in the grid study area were obtained from the Air Quality Section of the Utah State Division of Health. Airport locations were determined from 1/24,000 scale U.S.G.S. maps and assigned to the appropriate grids. 12 ------- Three methods were used to determine the vehicle miles travelled in the grid areas. Traffic flow maps were used for grids 117-120 and 124, 125 in Ogden and grids 289, 291, 298, 299, 301, 302, and 305 in the Provo area. Vehicle miles travelled in 239 traffic zones in the Salt Lake City area have been published. The grids for the present study were drawn over the 239 traffic zones and the VMT data was apportioned to grids 177, 179, 181, 186- 208, 211-230, 232, 237-2A6, 251-260. County VMT data were apportioned to all other grids by population. In Salt Lake county, 71% of the VMT were assigned to grids by the traffic zone method. Emissions from all of the above sources were calculated using area source emission factors and methods obtained from the Environmental Protection Agency in Durham, North Carolina. Tables 5 and 6 list the emission factors that were used. Appendix A describes the methods used to calculate motor vehicle emissions. A computer program was written and used to apportion sources to grids, to calculate emissipns, and to do the summations and calculations necessary for the final data output. .Point source emissions which had been previously calculated were assigned to grids by hand and included in the final computer outputs and summations. 13 ------- WASATCH FRONT INTRASTATE UTAH INTRASTATE (REMAINING AREA) FOUR CORNERS INTERSTATE (ARIZONA- COLORADO- NEW MEXICO- UTAH) Figure 1.

The first step in estimating motor vehicle emissions is to establish the mileage ratios for the different classes of vehicles: 1) Multiply gasoline fuel for light vehicles times 1000 times 13.6 (mpg) , 2) Multiply gasoline fuel for heavy vehicles times 1000 times 8.4 (mpg), 3) Multiply diesel fuel for heavy vehicles times 1000 times 5.0 (mpg). Add the products - SUM of vehicle miles: traveled. (M_) Obtain ratio of vehicle mile total for category of vehicle. (3) SUM If any measured vehicle miles are filled in, proceed as follows: Then multiply each ration from above times each "Measured Vehicle Miles" category, times appropriate emission factor, i.e. Limited Access Road - miles (M^) times 10,000 times ILD times appropriate emission factor plus M^ times 10,000 R,jnr, times appropriate emission factor plus M.. times 10,000 R,,nn times appropriate emission factor.
