Current through Register 2024 Notice Reg. No. 28, July 12, 2024
The operator of a facility who is required to report
						  under section
						  95101 of this article, and who is
						  not eligible for abbreviated reporting under section
						  95103(a), must
						  comply with Subpart H of 40 CFR Part 98 (§§
												98.80 to
						  98.88) in reporting annual
						  stationary combustion and process emissions and other data from cement
						  production to ARB, except as otherwise provided in this section.
(a) CO2
from
						Fossil Fuel Combustion
. When calculating CO2
						emissions from fuel combustion, the operator must use a method in
						40 CFR §
													98.33(a)(1) to §
												98.33(a)(4) as
						specified by fuel type in section
						95115 of this article.
(b)
Monitoring, Data and
						Records
. For each emissions calculation method chosen under section
						95110(a), the
						operator must meet the applicable requirements for monitoring, missing data
						procedures, data reporting, and records retention that are specified in
						40 CFR §
													98.34 to §
												98.37, except as modified in
						sections 95110(c)-(d),
						95115, and
						95129 of this article.
(c)
Missing Data Substitution
						Procedures
. The operator must comply with
						40 CFR §
													98.85 when substituting for missing data,
						except as otherwise provided in paragraphs (1)-(3) below.
(1) To substitute for missing data for
						emissions reported under section
						95115 of this article (stationary
						combustion units and units using continuous emissions monitoring systems), the
						operator must follow the requirements of section
						95129 of this article.
(2) If data for the carbonate content of
						clinker or cement kiln dust as required by
						40 CFR §
														98.83(d) are missing, and a
						new analysis cannot be undertaken, the operator must apply a substitute value
						according to the procedures in paragraphs (A)-(C) below.
(A) If the data capture rate is at least 90
						percent for the data year, the operator must substitute for each missing value
						using the best available estimate of the parameter, based on all available
						process data.
(B) If the data
						capture rate is at least 80 percent but not at least 90 percent for the data
						year, the operator must substitute for each missing value with the highest
						quality assured value recorded for the parameter during the given data year, as
						well as the two previous data years.
(C) If the data capture rate is less than 80
						percent for the data year, the operator must substitute for each missing value
						with the highest quality assured value recorded for the parameter in all
						records kept according to section
						95105(a).
(3) For each missing value of the monthly raw
						material consumption or monthly clinker production used to calculate emissions,
						the operator must apply a substitute value according to paragraphs (A)-(B)
						below.
(A) If the data capture rate is at
						least 80 percent for the data year, the operator must substitute for each
						missing value according to 40 CFR §
															98.85(c) or
						40 CFR §
															98.85(d), as
						applicable.
(B) If the data capture
						rate is less than 80 percent for the data year, the operator must substitute
						for each missing value with the maximum short tons of clinker per day capacity
						of the system or the maximum short tons per day raw material throughput of the
						kiln, as applicable, and the number of days per month.
(4) The operator must document and retain
						records of the procedure used for all missing data estimates pursuant to the
						recordkeeping requirements of section
						95105.
