The 1990 production of VC at each facility as estimated by first dividing the total annual production by total annual capacity for 1990, as reported tn "Chemical Products Synopsis - Vinyl Chloride", February, 1991. This factor was then multiplied by the capacity of each facility identified in the " 1990 Directory of Chemical Producers" to estimate the production at each facility. The emission factors from FIRE have units of "lb VC emitted per ton ethylene dichloride (EDC) * VC produced". Vinyl chloride is made from EDC, so these emission factors were assumed to be for the VC production part of the process, not EDC production. Hence, only VC production data was used to estimate emissions. The facility estimates for each chemical were summed to produce the 1990 national estimate of emissions from chemical manufacturing of vinyl chloride. Spatial allocation of the estimates for each chemical was based on the location of each facility identified in the "1990 Directory of Chemical Producers". Data Qualifiers: The emission factors in FIRE (0.720, 2.4 and 5.8 lb/ton) are representative of uncontrolled operations. These factors were added together to estimate VC emissions. Emission factors were only available for certain emission points, so this estimate may not include the entire amount of emissions from this source category. Example Calculations: Annual Production, VC produced: 10600 (million lbs VC produced) / 10200 (million lbs capacity to produce VC) = 1.039 1.039 x 800 (million lbs capacity to produce VC in 1990)9 831 million lbs VC produced at one facility VC Emission Factors: Uncontrolled EF = (0.720 + 2.4 + 5.8 lb/ton) " 8.920 lb VC / ton VC produced Emissions Estimate: 831 (million lbs VC produced) x (1 ton / 2000 lbs) x 8.92 lbs VC / ton VC produced = = 3707922 lbs VC x (1 ton / 2000 lbs) = 1854 tons vinyl chloride from chemical manufacturing of VC at a facility.

The 1990 production of TCEA at each facility was estimated by first dividing the total annual production by total annual capacity for 1990, as reported in "Chemical Products Synopsis -1,1,1-Trichloroethane", November, 1992. This factor was then multiplied by the capacity of each facility identified in the "1990 Directory of Chemical Producers" to estimate the production at each facility. The facility estimates for each chemical were summed to produce the 1990 national estimate of emissions from chemical manufacturing of 1,1,1-trichloroethane. Spatial allocation of the estimates for each chemical was based on the location of each facility identified in the "1990 Directory of Chemical Producers". Data Qualifiers: Vinyl chloride emission factors in FIRE are applicable to distillation column vent emissions. Factors for uncontrolled emissions (0.0140 lb/ton) and controlled by incineration (0.0002 lb/ton) are presented. The factors are based on engineering judgement and are representative of a hypothetical plant with 38 lb/yr production capacity. The average of the uncontrolled and controlled emission factors was used to estimate emissions. Emission factors were only available for certain emission points, so this estimate may not include the entire amount of emissions from this category.

The 1990 production of EDC at each facility was estimated by first dividing the total annual production by total annual capacity for 1990, as reported in "Chemical Products Synopsis - Ethylene Dichloride", February, 1991. This factor was then multiplied by the capacity of each facility identified in the "1990 Directory of Chemical Producers" to estimate the production at each facility.

The 1990 production of PERC at each facility was estimated by first dividing the total annual production by total annual capacity for 1990, as reported in "Chemical Products Synopsis - Perchloroethylene", August, 1992. This factor was then multiplied by the capacity of each facility identified in the " 1990 Directory of Chemical Producers" to estimate the production at each facility. The vinyl chloride emission factors is applicable to facilities that co-produce both PERC and trichloroethylene (TCE). Production for these facilities was estimated by the same procedure described above. Only the capacity of the facilities identified in the 1990 Directory of Chemical Producers as co-producing these chemicals were included when estimating production for these chemicals. Capacity and production data for each chemical produced at a facility were added together when facilities co-produced the chemicals. The national production data used to estimate the production of TCE at each facility was reported in "Chemical Products Synopsis - Trichloroethylene", May 1995. The facility estimates for each chemical were summed to produce the 1990 national estimate of emissions from chemical manufacturing of perchloroethylene. Spatial allocation of the estimates for each chemical was based on the location of each facility identified in the "1990 Directory of Chemical Producers". Data Qualifiers: Emission factor in FIRE (1.04 lb VC/ton PERC & TCE produced) is representative of uncontrolled emissions from the oxychlorination process drying column vent. It is based on data from one source test from one producer. Production data for the only facility identified in the "Directory of Chemical Producers" to produce both PERC and TCE were included in this estimate. Emission factors were only available for certain emission points, so this estimate may not include the entire amount of emissions from this source category. Example Calculations: Annual Production, PERC and TCE Co-produced: 371 (million lbs PERC produced) + 183 (million lbs TCE produced / (630 + 230) million lbs capacity to produce PERC and TCE, 1990) = 0.6442 0.6442 x (200 million lbs capacity to produce PERC + 200 million lbs capacity to produce TCE, in 1990) = = 257.67 million lbs PERC and TCE at one facility Emissions Estimate: 257.67 (million lbs PERC & TCE produced) x (1 ton / 2000 lbs) x 1.04 lb vinyl chloride / ton PERC & TCE produced = 133988 lbs vinyl chloride x (1 ton / 2000 lbs) = 66.9942 tons vinyl chloride from chemical manufacturing of PERC & TCE at one facility.

The 1990 production of TCEA was estimated at each facility by first dividing the total annual production by total annual capacity for 1990, as reported in "Chemical Products Synopsis - 1,1,1-Trichloroethane", November, 1992. This factor was then multiplied by the capacity of each facility identified in the "1990 Directory of Chemical Producers" to estimate the production at each facility. The facility estimates for each chemical were summed to produce the 1990 national estimate of emissions from chemical manufacturing of 1,1,1-trichloroethane. Spatial allocation of the estimates for each chemical was based on the location of each facility identified in the "1990 Directory of Chemical Producers". Data Qualifiers: 1,2-Dichloroethane emission factors in FIRE are applicable to uncontrolled and controlled emissions from the production of TCEA from ethane (0.138 and 0.00200 lb/ton) and from vinyl chloride (0.360 and 0.00800 lb/ton). The average of the uncontrolled and controlled emission factors was used to estimate emissions. The "Chemical Products Synopsis - 1,1,1-Trichloroethane" reports the dominate process involves the hydrochlorination of vinyl chloride (VC). The " Chemical Product Synopsis - Ethylene Dichloride" identifies Vulcan Chemical as the only producer of TCEA that does not also manufacture vinyl chloride monomer. Based on this information, the factors applicable to production from ethane were used to estimate emissions from Vulcan Chemicals, and the factors applicable to production from vinyl chloride were used to estimate emissions from the other two facilities. Additional emission factors for hydrochlorinator vent (3.40 lb/ton) and hydrochlorinator vent condenser and steam stripper vent condenser (9.00 lb/ton) are also in FIRE. Due to the possibility of double counting emissions from the production of TCEA from VC, and the magnitude and age of these factors, they were not used to estimate emissions. Emission factors were only available for certain emission points, so this estimate may not include the entire amount of emissions from this source category. Example Calculations: Annual Production, TCEA produced 801 (million lbs TCEA produced) / 1050 (million lbs capacity to produce TCEA) = 0.7629 0.7629 x 500 (million lbs capacity to produce TCEA , 1990) = 381.43 million lbs TCEA produced at one facility Emissions Estimate: 0.360 + 0.008 (lb EDC / ton TCEA produced) / 2 = 0.184 lb EDC / ton TCEA produced 381.45 (million lbs TCEA produced) x (1 ton / 2000 lbs) x 0.184 lbs EDC / ton TCEA produced = = 35093 lbs EDC from chemical manufacturing of TCEA x (1 ton / 2000 lbs) = = 17.5467 tons EDC from chemical manufacturing of TCEA at one facility.

The 1990 production of PERC at each facility was estimated by first dividing the total annual production by total annual capacity for 1990, as reported in "Chemical Products Synopsis - Perchloroethylene", August, 1992. This factor was then multiplied by the capacity of each facility identified in the " 1990 Directory of Chemical Producers" to estimate the production at each facility. The emission factors for 1,2-dichloroethane (EDO) are applicable to facilities that co-produce both PERC and carbon tetrachloride. Production for these facilities was estimated by the same procedure described above. Only the capacity of the facilities identified in the 1990 Directory of Chemical Producers as co-producing these chemicals were included when estimating production for these chemicals. Capacity and production data for each chemical produced at a facility were added together when facilities co-produced the chemicals. The national production data used to estimate the production of TCE and carbon tetrachloride at each facility was reported in "Chemical Products Synopsis - Carbon Tetrachloride", October 1992. The facility estimates for each chemical were summed to produce the 1990 national estimate of emissions from chemical manufacturing of perchloroethylene. Spatial allocation of the estimates for each chemical was based on the location of each facility identified in the "1990 Directory of Chemical Producers". Data Qualifiers: Emission factors in FIRE are representative of the hydrocarbon chlorinolysis process, hex waste handling. Factors for EDC from uncontrolled sources (0.0S20 lb EDC/ton PERC & Carbon Tet. produced), and for sources controlled with activated carbon adsorption and miscellaneous control devices (0.000S2 lb EDC/ton PERC & Carbon Tet. produced) are listed. Since it is unknown which facilities employ controls, an average of the controlled and non-controlled emission facton was used to estimate emissions. Emission factors were only available for certain emission points, so this estimate may not include the entire amount of emissions from this source category. Production data for only those facilities identified in the "Directory of Chemical Producers" to produce both PERC and carbon tetrachloride were included in this estimate. Example Calculations: Annual Production, PERC and Carbon Tetrachloride Co-produced: 371 (million lbs PERC produced) + 409 (million lbs Carbon Tetrachloride produced / (630 x 2) million lbs capacity to produce PERC and Carbon Tet, 1990) = 0.6190 0.6190 x (50 million lbs capacity to produce PERC + 80 million lbs capacity to produce Carbon Tet, in 1990) = = 80470000 lbs PERC and Carbon Tetrachloride at one facility Emissions Estimate: (0.052 lb EDC/ton + 0.00052 lb EDC/ton) 12 = 0.0286 lb EDC / ton emission factor 80470000 (lbs PERC and Carbon Tetrachloride produced) x (1 ton / 2000 lbs) x 0.0286 lbs EDC / ton PERC & Carbon Tet produced = = 1150 lbs EDC x ( 1 ton / 2000 lbs) = 0.575 tons EDC from a facility References: U S.

The 1990 production of TCE was estimated by dividing the total annual production by total annual capacity for 1990, as reported in "Chemical Products Synopsis - Trichloroethylene", May, 1995. This factor was then multiplied by the capacity of each facility identified in the "1990 Directory of Chemical Producers" to estimate the production at each facility. The facility estimates for each chemical were summed individually to produce the 1990 national estimate of emissions from chemical manufacturing of trichloroethylene. Spatial allocation of the estimates for each chemical was based on the location of each facility identified in the "1990 Directory of Chemical Producers". Data Qualifiers: The ethylene dichloride emission factor from the L & E document, (5.0 kg EDC / Mg TCE produced) is applicable to controlled emissions from the production of TCE. This factor was calculated for the L & E document by dividing the 1977 reported TCE emissions by 90 percent of the total TCE production quantity in 1977. Emission factos were only available for certain emissin points, so this estimate may not include the entire amount of emissison from this source category. Example Calculations: Annual Production, TCE produced 183 (million lbs TCE produced) / 230 (million lbs capacity to produce TCE) = 0.79565 0.79565 x 120 (million lbs capacity to produce TCE , 1990) = 95.478 million lbs TCE produced at a facility Emission Factor: 5.0 (Kg EE>C / Mg TCE produced) x 1 Mg/1 metric ton x 1 metric ton/2200 lbs x 2000 lbs/ short ton= 4.545 Kg/ton 4 545 (Kg EDC / ton TCE produced) x 1.102E-3 /1 Kg = 0.0050091 tons EDC / ton TCE produced 0.0050091 tons EDC / ton TCE produced x 2000 lbs / ton = 10.018 lbs EDC / ton TCE produced Emissions Estimate: 95.478 (million lbs TCE produced) x (1 ton / 2000 lbs) x 10.018 EDC / ton TCE produced = = 485993 lbs TCE from chemical manufacturing of TCE x (1 ton / 2000 lbs)* = 242.99 tons TCE from chemical manufacturing of TCE at one facility.

Compilation of Air Pollutant Emission Factors, 5th Edition, AP-42, Volume 1: Stationary Point and Area Sources. Research Triangle Park, North Carolina. 1995. The HAP concentrations provided in the above reference are based on the EPA's Landfill Air Emissions Estimation model. In order to calculate mass emissions for each HAP, a total estimate of landfill gas has to be calculated. This calculation was done using the total mass of methane emitted on a national level. A national estimate of methane (CH4) generated (9.25E+9 kg/yr) from MSW landfills in the United States was obtained from the following reference: U.S. Environmental Protection Agency. Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-1994. Office of Policy, Planning and Evaluation, Washington, D.C. EPA-230-R-96-006. November 1995. The methane emissions estimate of 9.25E+9 kg/yr represents the average of the range (7.5 to II million metric tonnes) reported for U.S. methane emissions from landfills in 1990, excluding emissions from industrial landfills. Industrial landfills were excluded because the HAP concentrations provided in AP-42 do not represent industrial landfills. Using the AP-42 guidance, the national volumetric flow rate of CH4 (m3fyr) was calculated based on the national mass flow rate of CH4 (kg/yr), assuming that the average landfill gas temperature is 25C. Next the national volumetric flow rate of landfill gas (m3/yr) was calculated, based on the national volumetric flow rate of CH4 (m3/yr), assuming the landfill gas consists of 50 percent CH4 and 50 percent COj by volume. Landfills are generally considered uncontrolled sources so no emission reduction controls were assumed in estimating HAP emissions. Using equations provided in the AP-42 document to determine benzene (as an example) emissions, the national volumetric emission rate of benzene (m3/yr) was then calculated based on the national volumetric flow rate of landfill gas (m3/yr), assuming the benzene concentration in landfill gas is 2.25 ppmv (i.e., the benzene emission concentration provided in the AP-42 document for a MSW landfill with an "unknown" status with regard to co-disposal with hazardous waste). Similarly, the AP-42 concentrations of other pollutants addressed in this inventory were used to calculate their emissions. Finally, the national mass emission rate of benzene (kg/yr) was calculated, based on the national volumetric emission rate of benzene (m3/yr), assuming the landfill gas temperature is 25C.

A national estimate of methane (CH4) generated (9.25E+9 kg/yr) from MSW landfills in the United States was obtained from the following reference: U.S. Environmental Protection Agency. Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-1994. Office of Policy, Planning and Evaluation, Washington, D.C. EPA-230-R-96-006. November 1995. The methane emissions estimate of 9.25E+9 kg/yr represents the average of the range (7.5 to 11 million metric tonnes) reported for U.S. methane emissions from landfills in 1990, excluding emissions from industrial landfills. Industrial landfills were excluded because the HAP concentrations provided in AP-42 do not represent industrial landfills. Using the AP-42 guidance, the national volumetric flow rate of CH4 (m3/yr) was calculated based on the national mass flow rate of CH4 (kg/yr), assuming that the average landfill gas temperature is 25C. Next the national volumetric flow rate of landfill gas (m3/yr) was calculated, based on the national volumetric flow rate of CH4 (m3/yr), assuming the landfill gas consists of 50 percent CH4 and 50 percent CO2 by volume. Landfills are generally considered uncontrolled sources so no emission reduction controls were assumed in estimating HAP emissions. Using equations provided in the AP-42 document to determine benzene (as an example) emissions, the national volumetric emission rate of benzene (m3/yr) was then calculated based on the national volumetric flow rate of landfill gas (m3/yr), assuming the benzene concentration in landfill gas is 2.25 ppmv (i.e., the benzene emission concentration provided in the AP-42 document for a MSW landfill with an "unknown" status with regard to co-disposal with hazardous waste). Similarly, the AP-42 concentrations of other pollutants addressed in this inventory were used to calculate their emissions. Finally, the national mass emission rate of benzene (kg/yr) was calculated, based on the national volumetric emission rate of benzene (m3/yr), assuming the landfill gas temperature is 25*C.
