[1]The HHV for components of LPG determined at 60ºF and saturation pressure with the exception of ethylene.
[2]Ethylene HHV determined at 41ºF (5ºC) and saturation pressure.
[3]Use of this default HHV is allowed only for: (a) Units that combust MSW, do not generate steam, and are allowed to use Tier 1; (b) units that derive no more than 10 percent of their annual heat input from MSW and/or tires; and (c) small batch incinerators that combust no more than 1,000 tons of MSW per year.
[4]Reporters subject to subpart X of this part that are complying with §98.243(d) or subpart Y of this part may only use the default HHV and the default CO2 emission factor for fuel gas combustion under the conditions prescribed in §98.243(d)(2)(i) and (d)(2)(ii) and §98.252(a)(1) and (a)(2), respectively. Otherwise, reporters subject to subpart X or subpart Y shall use either Tier 3 (Equation C - 5) or Tier 4.
[5]Use the following formula to calculate a wet basis HHV for use in Equation C-1: HHVw=((100-M)/100)*HHVd where HHVw = wet basis HHV, M = moisture content(percent) and HHVd=dry basis HHV from Table C-1.

[a]Recirculated leachate (in inches/year) is the total volume of leachate recirculated from company records or engineering estimates divided by the area of the portion of the landfill containing waste with appropriate unit conversions. Alternatively, landfills that use leachate recirculation can elect to use the k value of 0.057 rather than calculating the recirculated leachate rate.
[b]Use the lesser value when precipitation plus recirculated leachate is less than 20 inches/year. Use the greater value when precipitation plus recirculated leachate is greater than 40 inches/year. Use the average of the range of values when precipitation plus recirculated leachate is 20 to 40 inches/year (inclusive). Alternatively, landfills that use leachate recirculation can elect to use the greater value rather than calculating the recirculated leachate rate.
[c]Use the lesser value when the potential evapotranspiration rate exceeds the mean annual precipitation rate plus recirculated leachate. Use the greater value when the potential evapotranspiration rate does not exceed the mean annual precipitation rate plus recirculated leachate. Alternatively, landfills that use leachate recirculation can elect to use the greater value rather than assessing the potential evapotranspiration rate or recirculated leachate rate.

Table HH - 4 to Subpart HH of Part 98 -- Landfill Methane Oxidation Fractions
Under these conditions:
Use this landfill methane oxidation fraction:

I.For all reporting years prior to the 2013 reporting year
C1: For all landfills regardless of cover type or methane flux
0.10
II. For the 2013 reporting year and all subsequent years
      * C2: For landfills that have a geomembrane (synthetic) cover with less than 12 inches of cover soil for the majority of the landfill area containing waste
      * 0.0

C3: For landfills that do not meet the conditions in C2 above, and for which you elect not to determine methane flux
0.10
C4: For landfills that do not meet the conditions in C2 above and that do not have a soil cover of at least 24 inches for a majority of the landfill area containing waste
0.10
C5: For landfills that have a soil cover of at least 24 inches for a majority of the landfill area containing waste and for which the methane flux rate is less than 10 grams per square meter per day (g/m[2]/d)
0.35
C6: For landfills that have a soil cover of at least 24 inches for a majority of the landfill area containing waste and for which the methane flux rate is 10 to 70 g/m[2]/d
0.25
C7: For landfills that have a soil cover of at least 24 inches for a majority of the landfill area containing waste and for which the methane flux rate is greater than 70 g/m[2]/d
0.10
[a]Methane flux rate (in grams per square meter per day; g/m[2]/d) is the mass flow rate of methane per unit area at the bottom of the surface soil prior to any oxidation and is calculated as follows:

For Equation HH-5 of this subpart, or for Equation TT-6 of subpart TT of this part,

For Equation HH-6 of this subpart,

For Equations HH-7 of this subpart,

For Equation HH-8 of this subpart,

Where:

MF = 	Methane flux rate from the landfill in the reporting year (grams per square meter per day, g/m[2]/d).

K = 	unit conversion factor = 10[6]/365 (g/metric ton per days/year) or 10[6]/366 for a leap year.

SArea = 	The surface area of the landfill containing waste at the beginning of the reporting year (square meters, m[2]).

GCH4 = 	Modeled methane generation rate in reporting year from Equation HH - 1 of this subpart or Equation TT-1 of subpart TT of this part, as applicable, except for application with Equation HH-6 of this subpart (metric tons CH4). For application with Equation HH-6 of this subpart, the greater of the modeled methane generation rate in reporting year from Equation HH - 1 of this subpart or Equation TT-1 of this part, as applicable, and the quantity of recovered CH4 from Equation HH - 4 of this subpart (metric tons CH4).

CE = 	Collection efficiency estimated at landfill, taking into account system coverage, operation, and cover system materials from Table HH - 3 of this subpart. If area by soil cover type information is not available, use default value of 0.75 (CE4 in table HH - 3 of this subpart) for all areas under active influence of the collection system.

N = 	Number of landfill gas measurement locations (associated with a destruction device or gas sent off-site). If a single monitoring location is used to monitor volumetric flow and CH4 concentration of the recovered gas sent to one or multiple destruction devices, then N=1.

Rn = 	Quantity of recovered CH4 from Equation HH - 4 of this subpart for the n[th] measurement location (metric tons).

fRec,n = 	Fraction of hours the recovery system associated with the n[th] measurement location was operating (annual operating hours/8760 hours per year or annual operating hours/8784 hours per year for a leap year).

[1]In the case of products blended with some portion of biomass-based fuel, the carbon share in Table MM - 1 of this subpart represents only the petroleum-based components.
[2]Products that are derived entirely from biomass should not be reported, but products that were derived from both biomass and a petroleum product (i.e., co-processed) should be reported as the petroleum product that it most closely represents.
[3]The density and emission factors for components of LPG determined at 60ºF and saturation pressure (LPGs other than ethylene)
[4]The density and emission factor for ethylene determined at 41ºF and saturation pressure.

aThe applicable climate classification is determined based on the annual rainfall plus the recirculated leachate application rate. Recirculated leachate application rate (in inches/year) is the total volume of leachate recirculated from company records or engineering estimates and applied to the landfill divided by the area of the portion of the landfill containing waste [with appropriate unit conversions].
(1) Dry climate = precipitation plus recirculated leachate less than 20 inches/year
(2) Moderate climate = precipitation plus recirculated leachate from 20 to 40 inches/year (inclusive)
(3) Wet climate = precipitation plus recirculated leachate greater than 40 inches/year
Alternatively, landfills that use leachate recirculation can elect to use the k value for wet climate rather than calculating the recirculated leachate rate.
