                 NEW YORK STATE NONPOINT SOURCE METHODOLOGIES

Nonpoint Sources (formerly referred to as `Area Sources') are sources considered too small to be included in the Annual Point Source Inventory Survey.  They are not required to obtain a Title V permit pursuant to 6 NYCRR 201-6. Some of the Nonpoint Source categories must have point source emissions subtracted out to avoid double counting depending on the Standard Industrial Classification (SIC) code. For example: Graphic Arts is a nonpoint source category, but there are Graphic Arts facilities that have high emission potentials such that they are required to obtain Title V permits. An activity like structure fires will not have point sources and therefore will not be subject to double counting.

The New York State (NYS) Nonpoint Source Inventory is part of the Periodic Inventory that is mandated by the 1990 Clean Air Act (§7502(c)(3) and §7511a(a)(3)(A)).  The Periodic Inventory is mandated to be completed every third year beginning with 1990 as the original base year. The Nonpoint Source Inventory for the 2008 Ozone National Ambient Air Quality Standard (NAAQS) Attainment State Implementation Plan (SIP) consists of categories with emissions calculated per county for each of the contaminants associated with the respective category.  The contaminants include three criteria contaminants:  carbon monoxide (CO), oxides of nitrogen (NOx) and volatile organic compounds (VOCs).  The base year for this inventory was 2011.

Emission factors utilized to calculate emissions from the various categories were derived or taken directly from Federal (United States Environmental Protection Agency, EPA) and State resources.  Federal references included EPA's AP-42, Factor Information Retrieval (FIRE 6.25) database, Emissions Inventory Improvement Program (EIIP), Landfill Air Emissions Estimation Model v2.01 (LAEEM) and "Technical Support Document, Emission Inventory Development for 2011 and 2017 for the Northeastern U.S., Beta Version".  The Federal references can be accessed at https://www.epa.gov/chief.  For each category, the basis of the emission factor(s) (employment, per capita (population), fuel use, etc.) and the respective reference(s) will be noted. If a category depended on a per capita emission factor, then the New York State population per county for the respective Periodic Inventory Year was downloaded from the New York Data Center located at Empire State Development.  The population data by county was obtained from the 2010 United States Census.

Architectural Coatings.  SCC: 2401001000
 
 	Emissions estimation was based on population and emissions factors. For the state of New York, that has architectural coatings regulations, an emission factor of 1.88 lbs. VOC / capita was used.
 
 	This activity is higher in the summer, (EPA's default adjustment: 1.3). A point source adjustment is not required for this nonpoint source category.  Total VOC emissions are reported in this inventory.

Asphalt Paving.  SCC: 2461022000

Estimating VOC emissions from Asphalt Paving are based on actual data obtained from the New York State Department of Transportation's Environmental Analysis Bureau, Air Quality Section for each county in the state. The data included the total amount of asphalt concrete, crack fill, and emulsions that was applied in each county during 2011.  The emission factor (9.2 lbs. VOC/barrel) was derived from the emission factor for emulsified asphalt listed in EIIP's Asphalt Paving (Page 17.5-8, Table 17.5-2, Volume III: Chapter 17). Since cutback asphalt is prohibited in New York State (See 6NYCRR Part 211.4(a)), there are no Hazardous Air Pollutants (HAPs) associated with this process. 

A point source adjustment is not required for this area source category.

Autobody Refinishing.  SCC: 2401005000

	Emissions for this category were estimated based on employment, SIC 7532. Based on federal and state's regulations, an emission factor of 94.69 lb VOC / employee was used. According to County Bureau Patterns, there were 6802 employees in Nassau County in 2011 under this SIC code. Therefore the VOC emissions listed under this category is 6802 employees X 94.69 lb VOC / employee = 644081.4 lb of VOC = 322.04 tons of VOC.

       Combustion (Commercial/Institutional, Industrial and Residential)

 The New York State Department of Environmental Conservation (NYSDEC) estimated emissions from nonpoint fuel combustion sources for three sectors: commercial/institutional, industrial and residential. The emission estimates were developed on a county-basis for eight fuels per sector (Area Source Codes (ASCs)) for a total of 23 ASCs. The 10-digit ASCs begin with 2102 for industrial, 2103 for commercial/institutional, and 2104 for residential source categories.

 State-wide fuel use estimates for calendar year 2011 were obtained from the New York State Energy Research and Development Authority (NYSERDA) for each sector.  Fuel usage at major facilities in 2011 in the State was determined from a NYSDEC database. The difference between the fuel usage reported by NYSERDA and by major facilities for each sector/fuel combination was allocated on a county-basis. The allocation was based upon census records or employment data and heating degree data (residential and commercial/institutional sectors only).

 The emission estimates for each county were calculated by multiplying the fuel allocation by the appropriate emission factors for each ASC. Emission factors were obtained from EPA (AP- 42 and FIRE 6.25 databases).  The emission factors were for boilers for each sector/fuel combination with one exception. Commercial sector distillate oil use was split between boilers and engines (93.8 percent boilers and 6.2 percent engines).

 There is no point source adjustment for the sector residential but point source adjustments were made by subtracting fuel use at major sources for the commercial/institutional and industrial sectors.  NOx, CO and VOC emissions were reported for this inventory.
 
Consumer and Commercial Solvents
 
Overview:

All emission factors are from EPA's Emission Inventory Improvement Program (EIIP), Volume III, Chapter 5, Consumer and Commercial Solvent Use. The consumer and commercial solvent source category includes a wide array of products including personal care products, household cleaning products and household pesticides.  However, all VOC emitting products used by businesses, institutions and numerous industrial manufacturing operations are also included.  Products included in this category are shown in Table 1 (see page 6). The majority of VOC's introduced into the atmosphere from this category is a result of evaporation of the solvent contained in the product or from the propellant.  There are two methods for estimating emissions for consumer and commercial solvent use that are recommended by the EIIP: 1) use of national average per capita emission factors (population based method) adjusted for state or local emission limits; and 2) surveying consumer and commercial product use or sales in the inventory area. The choice as to which one is employed depends on the desired level of accuracy as well as available data and resources. 

Methodology:

      The population based method was the method used to calculate the emissions per county for this category in 2011. The procedure for the population based method is outlined below:

       1.) Identify applicable state and local regulations.
          2.) Create a database (See Table 1: (EIIP, Volume III, Chapter 5, Section 4, Page 5.4-3, Table 5.4-1)) or spreadsheet with per capita emission factors for the source categories of interest.
          3.) Obtain population data for the base year of interest and allocate it to county level. 
          4.) Multiply per capita emission factors by the population per county to obtain overall emissions estimates.
          5.) Adjust estimated emissions for applicable regulations as needed.


Estimating VOCs:

       Sample Calculation:  To estimate VOC emissions from personal care products, (SCC 2460100000): 
       
       VOCs Emissions = (Population)*(Per Capita Emission Factor)
       
       Given a population of 1,339,532 for Nassau County, the VOC emissions from personal care products would be: 
       
       (1,339,532 persons)*(1.9 lb. VOC's/person/year) = 
       
       (2,545,110 lb. VOC/year)/ (2000lb/ton) =1273 tons VOC/year.

Dry Cleaning  SCC: 2420010000

Actual facility data were used furnished by the NYSDEC's Division of Air Resources' Bureau of Stationary Sources. Dry cleaning machines (transfer and dry-to-dry) using perchloroethylene (perc) are the main concern. Coin Operated and Petroleum Solvents machines are negligible in this inventory. A point source (SIC 7216) adjustment by county is necessary for this area source category. VOCs were reported for this category using the relation:  lb VOC = lb perc x10/85.

       Sample Calculation:  26,620 gallons of perc were consumed in Nassau County in 2011. The  amount of perc emitted was: 

26,620 gal*13.51 lb/gal = 359,636.2 lb of perc.

The amount of VOCs emitted was: 
359,636.2 lb perc*10 lb VOC / 85 lb perc = 42,329.2 lb of VOC.

Forest and Prescribed Fires

      EPA estimated emissions from these nonpoint source categories based on fires information and on software developed for this purpose. (These are day specific emission estimates for the above-mentioned fires).
      
      The emissions are estimated using the BlueSky/SMARTFIRE2 framework, as has been the case for this sector for several NEI cycles. Therefore NYSDEC is no longer involved in these calculations. 
      
Portable Fuel Containers (Gas Can) SCCs: 2501011011, 2501011012, 2501012011 and 2501012012.
      
Emissions estimated by this inventory come from residential and commercial containers. These emissions are generated in permeation, diurnal (storage), and transport-spillage (can filling). Emissions from equipment refueling, spillage, and refueling vapor displacement were estimated by NYSDEC's Mobile Source Program.
      
To estimate the emissions from residential containers, a California Air Resources Board (CARB) survey, EPA emission factors and New York State household data from "New York State 2011 Residential Housing Units" were used. To estimate emissions from commercial containers we used the CARB survey, EPA emission factors and number of business, (establishments), from "County Business Patterns", US Census Bureau. 
      
       A point source adjustment is not required for this area source category.
      
      Sample Calculation (SCC: 2501011011).  Nassau County in 2011 had 468,651 households and 46% of them had an average of 1.8 portable fuel containers. Therefore the total number of residential cans is:
      
      (468,651) * (0.46) * (1.8) = 388,043 cans.
      
      If we know the percentage of cans that contain fuel (70%), and the percentage that remain closed (53%), the average fill level (43%), the average volume of the cans (2.34 gals) and the permeation factor (1.57 g/gal-day), then we can calculate the permeation/day:
      
      388,043 cans * (0.7) * (0.53) * (0.43) * (1.57 g/gal-day) * (2.34 gal/can) = 227,425 g/day 
      
      227,425 g/day *1/453 lb/g *365 day/yr. = 183,370.8 lb. VOC / yr.
      
Gasoline Marketing (Stages I and II)
      The calculation methodology followed for estimating area source emissions for this category was taken from the Emission Inventory Improvement Program (EIIP), Volume 3, Chapter 11, Gasoline Marketing (Stage I and II), April 2001.  This methodology involves employing an emission factor relating emissions to the volume of gasoline distributed.
      
      There are three primary sources of information that contain emission factors regarding gasoline service operations:
      
                AP-42, Chapter 5, Section 2,
                EIIP, Volume III, Chapter 11, and
                FIRE 6.25
               
  These sources offer factors which are applied to gasoline consumption rates for each county in order to estimate emissions of toxic substances from tank filling, tank breathing, tank emptying, and vehicle fueling operations.  Tank filling operations are further broken out to include splash filling, submerged filling without controls, and balanced submerged filling. Information from the bureau of stationary sources gave us the percentage applied to each kind of tank filling activity. 
  
  VOC emissions for tank breathing, tank emptying, and vehicle fueling operations were speciated according to USEPA, Technical Guidance  -  Stage II Vapor Recovery Systems for Control of Vehicle Refueling Emissions at Gasoline Dispensing Facilities, Volume I, EPA-450/3-91-022a, November 1991.  Toxic emission estimates are provided for each county according to appropriate area source code.

A point source adjustment is not required for these area source categories.  

      Sample Calculation: 511,557 * 10[3] gallons of gasoline were downloaded into gas stations in Nassau County in 2011 distributed this way: 30,693.4 * 10[3] gal in splash filling (6%), 20,462.3 * 103 gal in submerged filling (4%), and 460,401.3 * 103 gal in balanced submerged filling (90%). 
      
      Therefore their corresponding emissions were:
      
      SCC: 2501060051 (Submerged filling): 
      20,462.3x103 gal * (7.3 lb VOC /10[3] gal) = 149,374.6 lb VOC
      
      SCC: 2501060052 (Splash filling): 
      30,693.4x10[3] gal * (11.5 lb VOC /10[3] gal) = 352,974.3 lb VOC 
      
      SCC: 2501060053 (Balanced Submerged filling): 
      460,401.3x103 gal * (.3 lbs. VOC / 10[3] gal) = 138,120.4 lb VOC.

Using the same EIIP methodologies, emissions were also calculated for Pipelines, SCC: 2505040120, Bulk Terminals, SCC: 2501050120, Bulk Plants, SCC: 2501055120, and Tank Trucks in transit, SCC: 2505030120. Bulk Terminals Emissions were adjusted for point sources.

 Graphic Arts  SCC: 2425000000

 Volatile Organic Compounds (VOCs) emissions for the area source category Graphic Arts were calculated using an emission factor based on per capita (population) which was 1.3 lb VOC/person/year (0.00065 tons VOC/person/year). The emission factor was taken from EPA's Emission Inventory Improvement Program (EIIP), Volume III, Chapter 7, pages 7.5-10 thru 7.5-11.

 VOC's speciation was accomplished using EPA's program SPECIATE (version 3.2).  Profile Code: 2424 with TOG = 1.068719*VOC. The program can be downloaded from: www3.epa.gov/ttnchie1/software/speciate/
 
	A point source adjustment is required for this area source category.

Human Cremation  SCC: 2810060100

Emissions from human cremation in New York State (NYS) were calculated using the following equation:  
Emissions = (Bodies Cremated*Average Weight/Corpse (lb.)*Emission Factor (lb./ton))*ton/2000 lb.

The number of bodies cremated in NYS was calculated based on the number of deaths in NYS for 2011, which was provided by the New York State Department of Health and the NYS cremation rate (22%), which was provided by the Cremation Society (United States Cremation Statistics): 

Number of Bodies Cremated = (2011 Deaths in NYS)*(NYS Cremation Rate). The average weight per corpse is 150 lb. 

 Emission Factors were based on the California Air Resources Board's (CARB) test report No. C-90-004. Listed below are the emission factors in lb/ton for the respective contaminants which were inventoried for this category.

      Sample Calculation: According to DOH Nassau County, 11,190 deaths were reported in 2011. Assuming 22% of those bodies were cremated, we have: 
      11,190 * 0.22 = 2462 bodies cremated. 
      The tons cremated are: 
      2461 *150/2000 = 184.635 tons. 
      Therefore the VOC emissions due to cremation are: 
      184.635 tons * 0.083333336 = 15.4 lb VOC.
 
 Industrial Surface Coatings
 
 Emissions estimated from industrial surface coating processes (11 processes) were based on employment data and EPA emission factors (EIIP, Volume III, Chapter 8, Industrial Surface Coating, Table 8.5-1 (see below), page 8.5-2, September 1997).  Throughput for the per employee emission factors was provided by the New York State Department of Labor (NYDOL), Division of Research and Statistics and was compiled based on the North American Industry Classification System (NAICS) which replaced the SIC system of codes. The respective SIC Codes listed in Table 8.5-1 were matched with the equivalent NAICS code provided by the United States Census and forwarded to the NYSDOL for compilation. The NAICS codes can be accessed at the following website: www.census.gov/. Using the appropriate emission factor (lb VOC/year/employee) for the respective process, which already includes control efficiency, if any existed for the process, VOC emissions for each process were calculated for each county.

      Sample Calculation: According to Department of Labor in 2011 we had 1505 employees working in Aircraft 
      
      Manufacturing in Nassau County:  Since according to table it is assumed 12.98 lb VOC / Employee, then the total VOC emissions allocated to this activities are: 
      1505 employees * 12.98 lb VOC / employee = 19534.9 lb
      

 Municipal Solid Waste (MSW) Landfills  SCC: 2620030000
      
 Estimating emissions from MSW Landfills were based on actual MSW Landfill data compiled from NYSDEC's Division of Solid and Hazardous Materials for the years 1988 through 2011.  Utilizing the landfill data and the appropriate default values from Section 2.4, Pages 2.4-3 and 2.4-4 of EPA's AP-42 the emissions for NMOCs and the associated Hazardous Air Pollutants (HAPs) were calculated using EPA's Landfill Air Emissions Estimation Model (LAEEM). It was assumed that the landfill data was for co-disposal, therefore the C (NMOC) value of 2,420 ppmv as hexane was entered into the LAEEM.  Since New York receives 25 inches or more of rain per year the default value 0.04/yr was used for k and entered into the LAEEM.  

      
 Point source emissions will have to be subtracted from nonpoint emissions by county for MSW landfills.
      
Open Burning: Yard Waste: Leaf and Brush Species SCCs: 2610000100 and 2610000400 

	The amount of leaf and brush waste burned was estimated using data from EPA's report entitled "Municipal Solid Waste Generation, Recycling, and Disposal in the United States: Facts and Figures for 2011". The report presents the total mass of waste generated from the residential and commercial sectors, including yard waste, in the United States by type of waste for the calendar year 2011.  According to the EPA report, residential waste generation accounts for 55-65 percent of the total waste from the residential and commercial sectors. For the calculation of per capita yard waste subject to burning, the median value of 60 percent was assumed.  This information was used to calculate a daily estimate of the per capita yard waste of 0.36 lb/person/day.  Of the total amount of yard waste generated, the yard waste composition was assumed to be 25 percent leaves, 25 percent brush, and 50 percent grass, by weight. 

	Open burning of grass clippings is not typically practiced by homeowners, and as such only estimates for leaf burning and brush burning were developed.  Approximately 25 to 32 percent of all waste that is subject to open burning is actually burned. A median value of 28 percent is assumed to be burned in all counties in the United States.

      The per capita estimate was then multiplied by the 2011 population in each county that is expected to burn waste.  Since open burning is generally not practiced in urban areas, only the rural population of each county was assumed to practice open burning.  The ratio of urban to rural population was obtained from 2011 U.S. Census data. This ratio was then multiplied by the 2011 U.S. Census Bureau estimate of the population in each county to obtain the county-level rural population for 2011.

Emission Factors for leaves:  28 lb VOC / ton burned. 112 lb CO / ton burned. 6.2 lb NOX / ton burned.

Emission factors for brush:  19 lb VOC / ton burned. 140 lb CO / ton burned. 5 lb NOX / ton burned.

Open Burning: Land Clearing Debris SCC: 2610000500.    

      Open burning of land clearing debris is the purposeful burning of debris, such as trees, shrubs, and brush, from the clearing of land for the construction of new buildings and highways. Criteria air pollutant (CAP) and hazardous air pollutant (HAP) emission estimates from open burning of land clearing debris are a function of the amount of material or fuel subject to burning.

      Sample Calculations:
      
      VOC emissions in a county from open burning of land clearing debris:

      Rural fraction of that county population = 0.42, so no emission controls
      
      Acres disturbed by residential, non-residential, and road construction in the county = 84.83
      Weighted average fuel loading factor for the county = 65.48 tons/acre
      
      Mass of land clearing debris burned = 84.83 acres * 65.48 tons/acre = 5,555 tons
      
      VOC emission factor = 11.6 lb/ton
      Factor to convert from lbs. to tons = 1/2000
      
      VOC emissions = tons of land clearing debris burned * VOC emission factor
      
      VOC emissions from land clearing debris burning = 5,555 tons * 11.6 lb /ton
      
      VOC emissions from land clearing debris burning in the county in 2011 = 32.2 tons
      
      CO Emission Factor: 169 lb/ ton
      
      CO emissions from land clearing debris burning = 5,555 tons * 169 lb/ton
      
      CO emissions from land clearing debris burning in the county in 2011 = 469.4 tons
      
      NOX Emission factor:  5 lb/ ton burned.
      
      NOX emissions from land clearing debris burning = 5,555 tons * 5 lb/ton
      
      NOX emissions from land clearing debris burning in the county in 2011 = 13.9 tons.
      
 Public Owned Treatment Works (POTW)  SCC: 2630020000
      
 Publicly owned treatment works (POTW) facilities are owned by the State, municipalities, inter-municipality or interstate agencies, and departments/agencies of the federal government.  The definition of a POTW facility includes intercepting sewers, outfall sewers, sewage collection systems, pumping, power, and other equipment.  A typical POTW usually consists of a grit chamber for storage, a lift station for collection, a primary clarifier for settling solids, a bio-treatment process for biological waste treatment, a secondary clarifier for settling, a sludge digester, and a chlorine tank for disinfecting.  The wastewater treated by these POTWs is generated from industrial, commercial, and domestic sources.  The emission estimates for POTW facilities were calculated using 2011 flow rates provided by the Division of Water and then applying emission factors for VOCs, ammonia, and 53 HAPs.   Great Lakes issued a table of emission factors for estimation of HAPs generated through volatilization at the surface of the wastewater during treatment processes. Emissions were allocated to the county-level by the county flow rate. Point source emissions were subtracted from the county totals.  
VOC Emission Factor: 0.85 lb VOC/million gallons.
 
 Solvent Cleaning  SCC: 2460000000
 
 The method used to estimate VOC emissions from the solvent cleaning category was described in The Emission Inventory Improvement Program's (EIIP), Volume 3 (Area Sources and Area Source Method Abstracts), Solvent Cleaning Chapter (Chapter 6; Section 5.1.2; Pages 6.5-1 thru 6.5-4).  The emission factors used were the Per Employee Emission Factors (lb/yr./employee) listed in Table 6.5-2 (Page 6.5-4). Throughput for the per employee emission factors was provided by the New York State Department of Labor (NYDOL), Division of Research and Statistics and was compiled based on the NAICS codes.  The respective SIC Codes listed in Table 6.5-2 were matched with the equivalent NAICS code provided by the United States Census and forwarded to the NYSDOL for compilation.  The NAICS codes can be accessed at the following website: www.census.gov.
