(a) The CO₂ authorized account representative of a CO₂ budget unit that co-fires eligible biomass as a compliance mechanism under this Part shall report the following information to the department or its agent for each calendar quarter:

1. (1) For each shipment of solid eligible biomass fuel fired at the CO₂ budget unit, the total eligible biomass fuel input, on an as-fired basis, in pounds.
2. (2) For each shipment of solid eligible biomass fuel fired at the CO₂ budget unit, the moisture content, on an as-fired basis, as a fraction by weight.
3. (3) For each distinct type of gaseous eligible biomass fuel fired at the CO₂ budget unit, the density of the biogas, on an as-fired basis, in pounds per standard cubic foot.
4. (4) For each distinct type of gaseous eligible biomass fuel fired at the CO₂ budget unit, the moisture content of the biogas, as a fraction by total weight.
5. (5) For each distinct type of gaseous eligible biomass fuel fired at the CO₂ budget unit, the total eligible biomass fuel input, in standard cubic feet.
6. (6) For each distinct type of eligible biomass fuel fired at the CO₂ budget unit, the dry basis carbon content of the fuel type, as a fraction by dry weight.
7. (7) For each distinct type of eligible biomass fuel fired at the CO₂ budget unit, the dry basis higher heating value, in MMBtu per dry pound.
8. (8) For each distinct type of eligible biomass fuel fired at the CO₂ budget unit, the total dry basis eligible biomass fuel input, in pounds, calculated in accordance with subdivision (b) of this section.
9. (9) The total amount of CO₂ emitted from the CO₂ budget unit due to firing eligible biomass fuel, in tons, calculated in accordance with subdivision (c) of this section.
10. (10) For each distinct type of eligible biomass fuel fired at the CO₂ budget unit, the total eligible biomass fuel heat input, in MMBtu, calculated in accordance with paragraph (d)(1) of this section.
11. (11) The total amount of heat input to the CO₂ budget unit due to firing eligible biomass fuel, in MMBtu, calculated in accordance with paragraph (d)(2) of this section.
12. (12) Description and documentation of monitoring technology employed, and description and documentation of fuel sampling methodology employed, including sampling frequency; and
13. (13) For each distinct type of eligible biomass fuel fired at the CO₂ budget unit, chemical analysis, including heating value and carbon content.

(b) An owner or operator of a CO₂ budget unit shall calculate and submit to the department or its agent on a quarterly basis the total dry weight for each distinct type of eligible biomass fired by the CO₂ budget unit during the reporting quarter. The total dry weight shall be determined for each fuel type as follows:

1. (1) For solid fuel types: ​ where: F_j = Total eligible biomass dry basis fuel input (lbs) for fuel type j; F_i = Eligible biomass as fired fuel input (lbs) for fired shipment i; M_i = Moisture content (fraction) for fired shipment i; i = fired fuel shipment; j = fuel type; and, m = number of shipments.

   ​

2. (2) For gaseous fuel types: F_j = D_j x V_j x (1 - M_j) where: F_j = Total eligible biomass dry basis fuel input (lbs) for fuel type j; D_j = Density of biogas (lbs/scf) for fuel type j; V_j = Total volume (scf) for fuel type j; M_j = Moisture content (fraction) for fuel type j, j = fuel type.

(c) CO₂ emissions due to firing of eligible biomass shall be determined as follows:

1. (1) for any full calendar quarter during which no fuel other than eligible biomass is combusted at the CO₂ budget unit, as measured and recorded in accordance with sections 242-8.1 through 242-8.6 of this Subpart; or

2. (2) for any full calendar quarter during which fuels other than eligible biomass are combusted at the CO₂ budget unit, as determined using the following equation: ​ where: CO₂ tons = CO₂ emissions due to firing of eligible biomass for the reporting quarter; F_j = Total eligible biomass dry basis fuel input (lbs) for fuel type j, as calculated in subdivision (b) of this section; C_j = carbon fraction (dry basis) for fuel type j; O_j = Oxidation factor for eligible biomass fuel type j, derived for solid fuels based on the ash content of the eligible biomass fired and the carbon content of this ash, as determined pursuant to paragraph (a)(12) of this section; for gaseous eligible biomass fuels, a default oxidation factor of 0.995 may be used; 44/12 = The number of tons of carbon dioxide that are created when one ton of carbon is combusted (44/12); 0.0005 = The number of short tons which is equal to one pound; j = fuel type; and, n = number of distinct fuel types.

   ​

(d) Heat input due to firing of eligible biomass for each quarter shall be determined as follows:

1. (1) For each distinct fuel type: H_j = F_j x HHV_j where: H_j = Heat input (MMBtu) for fuel type j; F_j = Total eligible biomass dry basis fuel input (lbs) for fuel type j, as calculated in subdivision (b) of this section; HHV_j = Higher heating value (MMBtu/lb), dry basis, for fuel type j, as determined through chemical analysis; j = fuel type.

2. (2) For all fuel types: ​ where: H_j = Heat input (MMBtu) for fuel type j; j = fuel type; and, n = number of distinct fuel types.
