Cal. Code Regs. tit. 17, § 95113
(d) Calculating CO2from Flares. For periods of normal flare operation, the operator must use Equation Y-1a, Y-1b, or Y-2 as specified in 40 CFR § 98.253(b)(ii)(A) or 98.253(b)(ii)(B). For periods of startup, shutdown, and malfunction (SSM) during which the operator was unable to measure the parameters required by Equations Y-1a, Y-1b, or Y-2, the operator must determine the quantity of gas discharged to the flare separately for each SSM, and calculate the CO2 emissions as specified in the equation shown below. For SSM periods the operator must use engineering calculations and process knowledge to estimate the carbon content of flared gas as required by § 98.253(b)(iii)(A). The terms of the equation below are defined as they are for Equation Y-3 in 40 CFR § 98.253(b)(iii)(C).
)
(k) Missing Data Substitution Procedures. The operator must comply with 40 CFR § 98.255 when substituting for missing data, except as otherwise provided in paragraphs (1)-(2) below.
(2) For all other data required for emissions calculations in this section, the operator must follow the requirements of paragraphs (A)-(C) below.
(l) Additional Product and Process Data.
(3) Complexity Weighted Barrel (CWB) Calculation.
(B) Total facility CWB. The total facility CWB production must be calculated according to the following formula.
CWBTotal = CWBProcess + CWBOff-Sites + CWBNon-Crude Sensible Heat
Where CWBTotal is the total complexity weighted barrels for a petroleum refinery, and CWBProcess, CWBOff-Sites, and CWBNon-Crude Sensible Heat must be calculated as follows:
CWBProcess = Σ(CWBFactor x Throughput)
CWBOff-Sites = (0.327) x (Total Refinery Input in thousands of barrels per year) + (0.0085) x (CWBProcess)
CWBNon-Crude Sensible Heat = (0.44) x (Non-Crude Input in thousands of barrels per year)
In these equations, CWBFactor is the CWB Factor for a CWB unit from Table 2-2 of this section. Throughput is the process throughput for each CWB unit identified in Table 2-2 of this section reported pursuant to section 95113(l)(3)(A). Total Refinery Input and Non-Crude Input are the annual volumes of raw materials as defined in section 95102(c) and must be reported in units of thousands of barrels per year. Total facility CWB is covered product data and subject to material misstatement evaluation during verification.
(C) Correction to CWBFactorfor Fluid Catalytic Cracking. The following equation must be used to adjust CWBFactor for Fluid Catalytic Cracking (FCC) units and mild residual FCC units that result in coke on the catalyst:
CWBFactor,FCC = CWBFactor + (A x COC)
Where:
CWBFactor,FCC = The corrected CWB factor used to calculate the contribution to CWBProcess for a fluid catalytic cracking unit.
CWBFactor = The uncorrected CWB factor for a catalytic cracking unit from Table 2-2 of this section.
A = The coke-on-catalyst factor for a fluid catalytic cracking unit listed in the fourth column of Table 2-2 of this section.
COC = The coke-on-catalyst volume percent reported to three significant figures and calculated by:
COC = 100 x (Volume of coke consumed in the FCC)/(Volume of fresh feed to the FCC)
(D) Density. In cases where a density measurement is needed for purposes of converting a throughput from barrel to mass units, the following applies:
(m) Reporting to Support the Cost of Implementation Fee Regulation. The operator must report the volume of:
(3) California Diesel, as defined by “California diesel fuel” in section 95202 of the AB 32 Cost of Implementation Fee Regulation, produced and imported for use in California and the volume of biodiesel and/or renewable diesel associated with the reported fuels.
