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 P of 40 CFR Part 98 (40 CFR §§
													98.160 to
						  98.168) in reporting emissions and
						  other data from molecular hydrogen production to ARB, except as otherwise
						  provided in this section. GHG emissions and output associated with hydrogen
						  production must be reported separately from other emissions and output
						  associated with a petroleum refinery.
(a)
Definition of Source
						Category.
This source category is defined consistent with
						40 CFR §
													98.160(b) and(c). This
						category is further defined as a hydrogen production source that produces
						molecular hydrogen whether sold to other entities or consumed
						on-site.
(b)
						CO2
from Fossil Fuel Combustion
. When
						calculating CO2 emissions from fuel combustion under
						subpart C as specified at 40
						CFR §
													98.162(b)-(c),
						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.
(c)
Monitoring, Data and
						Records
. For each emissions calculation method chosen under section
						95114(b), 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 95114(h),
						95115, and
						95129 of this article.
(d) CO2
Emissions from Hydrogen Production Units.
When calculating
						CO2 emissions from hydrogen production units under the
						fuel and feedstock material balance approach specified at
						40 CFR §
													98.163(b), the operator must
						apply the weighted average carbon content values (the term
						CCn in Equations P-1 through P-3) and, for gaseous fuels
						and feedstocks, the weighted average molecular weight values obtained according
						to the frequencies specified in section
						95114(e)(2).
(e)
Fuel and Feedstock
						Contents
. For each hydrogen production unit, operators must report the
						following information:
(1) When monitoring GHG
						emissions with a CEMS as specified in
						40 CFR §
														98.163(a), the operator must
						report the monthly carbon content, atomic hydrogen content (excluding hydrogen
						atoms contained in steam), and molecular hydrogen content for each feedstock.
						The reported values must be weighted averages from the results of one or more
						analyses per month.
(2) When
						monitoring GHG emissions without a CEMS as specified in
						40 CFR §
														98.163(b), the operator must
						report the monthly weighted average atomic hydrogen content (excluding hydrogen
						atoms contained in steam) and weighted average molecular hydrogen content for
						each feedstock from the results of one or more analyses per month. The operator
						must also report the monthly carbon content for each fuel and feedstock, and
						the molecular weight for each gaseous fuel and feedstock as follows:
(A) The reported values must be weighted
						averages from the results of one or more analyses per month for natural gas or
						standardized materials specified in Table 2-3 of section
						95115.
(B) The reported values must be weighted
						averages from the results of daily sampling for each month for nonstandard
						materials not specified in Table 2-3 of section
						95115, such as refinery fuel gas.
						For liquid and solid fuels and feedstocks, daily samples may be combined to
						generate a monthly composite sample for carbon content
						analysis.
