California Code of Regulations › Title 13 - Motor Vehicles › Division 3 - Air Resources Board › Chapter 15 - Additional off-Road Vehicles and Engines Pollution Control Requirements › Article 3 - Verification Procedure, Warranty, and in-Use Compliance Requirements for Retrofits to Control Emissions from off-Road Large Spark-Ignition Engines › Section 2789 - In-Use Compliance Requirements

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
Applicability
. These in-use compliance requirements apply to
				  all LSI retrofit emission control systems for off-road applications. It is the
				  responsibility of the applicant to perform in-use compliance testing for each
				  verified LSI retrofit emission control group. Testing is required when 50 units
				  within a given LSI retrofit emission group have been sold or leased in the
				  California market.
(b)
Test
				  Period.
Applicants must obtain access to and test LSI retrofit
				  emission control systems, as described below in (c), (d), and (e), once they
				  have been operated between 1,500 and 2,000 hours or between 22 and 29 months,
				  whichever comes first.
(c)
Selection of LSI Retrofit Emission Control Systems for
				  Testing.
For each LSI retrofit emission control group, the Executive
				  Officer will identify a representative sample of engines or equipment equipped
				  with LSI retrofit emission control systems for in-use compliance testing. The
				  engines or equipment with the selected LSI retrofit emission control systems
				  installed must have good maintenance records and may receive a tune-up or
				  normal maintenance prior to testing. The applicant must obtain information from
				  the end users regarding the accumulated hours of usage, maintenance records (to
				  the extent practicable), operating conditions and a description of any
				  unscheduled maintenance that may affect the emission results. If the specified
				  information is not available for the engine or equipment selected, the
				  Executive Officer may select a different engine or equipment for testing. Upon
				  notification that an engine or equipment has been selected, an applicant would
				  have 6 months to provide an in-use compliance testing proposal for approval by
				  the Executive Officer. Testing would begin when the engines had accumulated
				  sufficient hours of service; testing must be completed within one year of
				  notification.
(d)
Number of
				  LSI Retrofit Emission Control Systems to be Tested.
The number of LSI
				  retrofit emission control systems an applicant must test will be determined as
				  follows:
(1) A minimum of four LSI retrofit
				  emission control systems in each LSI retrofit emission control group must be
				  tested. For every system tested that does not reduce emissions by at least 90
				  percent of the lower bound of its initial verification level, two more LSI
				  retrofit emission control systems from the same group must be obtained and
				  tested. The total number of systems tested shall not exceed ten per LSI
				  retrofit emission control group.
(2) At the discretion of the Executive
				  Officer, applicants may begin by testing more than the minimum of four LSI
				  retrofit emission control systems. Applicants may concede failure of an
				  emission control system before testing a total of ten LSI retrofit emission
				  control systems.
