Except for WEC applicable facilities with a waste emissions threshold of zero as determined in § 99.20(e), the total facility applicable emissions and WEC applicable emissions for each WEC applicable facility for the reporting year will be calculated as described in paragraphs (a) through (d) of this section, as applicable. If the waste emissions threshold for a WEC applicable facility is zero as determined in § 99.20(e), then the total facility applicable emissions and WEC applicable emissions for the WEC applicable facility are zero and paragraphs (a) through (d) of this section do not apply to the WEC applicable facility.
(a) The total facility applicable emissions for each WEC applicable facility will be calculated using equation B-6 of this section.
Where:
ETFA,CH4 = The annual methane emissions equal to, below, or exceeding the waste emissions threshold for a WEC applicable facility prior to consideration of any applicable exemptions (i.e., total facility applicable emissions), mt CH4.
ESubpartW,CH4 = The annual methane emissions for a WEC applicable facility, as reported to § 99.7(b)(2)(ix), mt CH4.
THWAF = The waste emissions threshold for a WEC applicable facility, as determined in § 99.20(e), mt CH4.
(b) If the total facility applicable emissions calculated using equation B-6 of this section are less than or equal to 0 mt, then the WEC applicable emissions are equal to the total facility applicable emissions.
(c) If the total facility applicable emissions calculated using equation B-6 of this section are greater than 0 mt and the regulatory compliance exemption as specified in § 99.41 applies for the entire reporting year and to all sites at the WEC applicable facility, the WEC applicable emissions for that facility are equal to 0 mt.
(d) If the total facility applicable emissions calculated using equation B-6 of this section are greater than 0 mt and the regulatory compliance exemption as specified in § 99.41 does not apply for the entire reporting year or does not apply to all sites at the WEC applicable facility, the WEC applicable emissions for each WEC applicable facility will be calculated using equation B-7 of this section. If the result of this calculation is less than 0 mt CH4, the WEC applicable emissions for the facility are equal to 0 mt CH4.
Where:
EWA,CH4 = The annual methane emissions associated with a WEC applicable facility that are either equal to, below, or exceeding the waste emissions threshold for the WEC applicable facility (i.e., the WEC applicable emissions), mt CH4.
ETFA,CH4 = The annual methane emissions equal to, below, or exceeding the waste emissions threshold for a WEC applicable facility prior to consideration of any applicable exemptions for the reporting year, mt CH4.
EDelay,CH4 = The quantity of methane emissions exempted, as determined in equation C-1 of § 99.32, at the WEC applicable facility due to an unreasonable delay in environmental permitting of gathering or transmission infrastructure meeting the applicability provisions of § 99.30, mt CH4.
ERCE,CH4 = The quantity of methane emissions, as determined pursuant to § 99.43, at the WEC applicable facility attributable to the regulatory compliance exemption subject to the applicability provisions of § 99.41, mt CH4.
EPlug,CH4 = The total quantity of annual methane emissions, as determined in equation E-7 of § 99.52, at the WEC applicable facility attributable to all wells that were permanently shut-in and plugged during the reporting year meeting the applicability provisions of § 99.50, mt CH4.
