1The HHV for components of LPG determined at 60 °F and saturation pressure with the exception of ethylene.

2Ethylene HHV determined at 41 °F (5 °C) and saturation pressure.

3Use 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.

...

4Reporters 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.

...

5Use 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.
