Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) To confirm
				  that the performance-based evaporative certification option in section
				  2754(a)
				  and the design-based evaporative certification option in section
				  2754(b)
				  are achieving CARB's overall emission reduction goals, CARB will conduct an
				  inventory validation study utilizing diurnal test data from such
				  equipment.
(b) This validation
				  study will be conducted at two time periods:
(a) in 2010 for the years 2008, 2009 and 2010
				  and (b) in 2015 for the years 2013, 2014 and 2015.
(c) For each year in the study, the Executive
				  Officer will select engine and/or equipment evaporative families and request,
				  from the certificate holder, one production unit from each identified family
				  from production inventory according to a method specified by the Executive
				  Officer. Diurnal testing of each selected unit (including the complete
				  evaporative emission control system) will be conducted pursuant to TP-902,
				  including pre-conditioning. Unless otherwise directed by the Executive Officer,
				  three data points will be generated and submitted to the Executive Officer for
				  each engine and / or equipment tested.
(d) The number of data points and equipment
				  to be tested for this validation study is as follows:
Year

								(# of Equipment Tested) for Units Certified per the Performance-Based Standards
								Under Section
								2754(a)

(e) The costs for testing engines or
				  equipment certified under the design-based element of the validation study are
				  the responsibility of the certificate holder. The costs for testing engines or
				  equipment certified under the performance-based element of the validation study
				  are the responsibility of CARB. For each of the years 2010 and 2015, the
				  Executive Officer will also review the annual performance-based and
				  design-based certification submissions for that year and two prior years (i.e.,
				  2010, 2009, 2008 for the 2010 validation and 2015, 2014, 2013 for the 2015
				  validation) to supplement this validation study.
(f) The Executive Officer will evaluate the
				  data collected and, based on reasonable criteria, make a determination whether
				  the performance-based option in section
				  2754(a)
				  and the design-based option in section
				  2754(b)
				  are achieving CARB's overall emission reduction goals. In making this
				  determination, the Executive Officer will consider, among other things, whether
				  a particular product tested is in full compliance with the underlying standards
				  and whether the product configurations are non-representative (i.e., large
				  tanks).
