Sample Calculations for Nonpoint SourcesAPPENDIX I- Sample calculations for several NonPoint Sources are below:

2007 Prescribed Burning

AMS: 2810014000 Suffolk County, NY (FIPS: 36103)

PM2.5 Flaming Fuel Em ission Calculations:

((Acres burned) 1 × (Fuel Loading Factor (tons/acre burned)) 2 × (PM2.5 Flaming Fuel Emission Factor (lb/ton))) 2 × 0.75 = PM2.5 Flaming Fuel Emissions (lbs/yr)

((77.5 acres burned) × (8.2 tons/acr e burned) × (24.1 lb/ton)) × 0.75 = 11,490 lbs/yr

PM2.5 Smoldering Fuel Emission Calculations:

((Acres burned) 1 × (Fuel Loading Factor (tons/acre burned)) 2 × (PM2.5 Emission Factor (lb/ton))) 3 × 0.25 = PM2.5 Smol dering Fuel Emissions (lbs/yr)

((77.5 acres burned) × (8.2 tons/a cre burned) × (24.1 lb/ton)) × 0.25 = 3,830 lbs/yr

PM2.5 Annual Emissions = PM2.5 Flaming Fuel Emissions + PM2.5 Smoldering Fuel Emissions = 11,490 lbs/yr + 3,830 lbs/yr = 15,320 lbs/yr = 7.66 tons/yr

Conservation’s Division of Lands And Forests.

1996 Base Year National Toxics Inventor y for Area Sources dated May 31, 2001 (Appendix A; Pages A-31 and A-32).

3. PM2.5 Emission Factor : The PM2.5 emission fact or (24.1 lbs/ton) was forwarded to the Department’s Division of Air Resources in an email from Randy

Strait of E. H. Pechan & A ssociates, Inc. on 08/02/2004.2007 Residential Heating (Oil)

AMS: 2104004000 & 2104011000 Nassau, NY (FIPS: 36059)

1. County: Nassau

2. Allocation of Fuel to County Level

a. Raw Data

i number of households heated w/oil: 247,586 (2000 Census) ii heating degree days (2007 cal endar year): 5,252 days (NOAA) iii statewide fuel usage for sector:

distillate oil: 1,338,120 x 10 3 gallons
kerosene: 52,164 x 10 3 gallons

b. Weighted Average Allocation

For each county, the product of c ensus data times heating degree days was determined. For Nassau County:

= (247,586 homes)(5,2 52 heating degree days)
= 1,300,321,672 homes -heating degree days

The statewide sum: 12,925, 564,782 homes-heating degree days

The Nassau County allocation factor (AF) for residential fuel oil then is calculated by dividing the county-specif ic value by the statewide value:

AF = (1,209,210,024)/(11,988,704,610)

AF = 0.1006

The residential fuel oil allocation for Nassau County is then determined by multiplying the statewide fuel usage for the sector by AF:

distillate oil: (0.1006)(1,338,120 x 10 3 gallons)

= 134,615 x 10 3 gallons

kerosene: (0.1006)(52,164 x 10 3 gallons)

= 5,248 x 10 3 gallons

3. Emission Factors

a. sulfur content of fuel oil:distillate oil: 0.21 percent kerosene: 0.053 percent

NOTE: Sulfur content in fuel oil as reported on 2007 Emission Statements submitted by fac ilities in Rockland and Nassau

Counties.

b. Area Source Classifications:

distillate oil: 2104004000

kerosene: 2104011000

c. Emission Factors (EF)

distillate or kerosene.

4. Emissions Calculations – Resi dential Heating O il – Nassau County

a. Annual

Emissions calculated by multiplying f uel allocation by emission factors. Sample calculations presented below:

PM 10 (5,248 x 10 3 gallons)(2.38 lb/10 3 gallons) = 12,490 lb = 6.2 tons
