Current through Register 2024 Notice Reg. No. 38, September 20, 2024
(a) The applicant must demonstrate
compatibility of its diesel emission control strategy in the field with at
least one vehicle or piece of equipment belonging to the initial emission
control group for which it seeks verification. Note that if the durability
demonstration selected by the applicant is in-field, it may be used to satisfy
the field demonstration requirement for that emission control group.
(1) Compatibility is determined by the
Executive Officer based on the third-party statement (see part (c) of this
section) and any other data submitted including backpressure data. A diesel
emission control strategy is compatible with the chosen application if it:
(A) Does not cause damage to the engine or
engine malfunction
(B) Does not
cause backpressure outside of the engine manufacturer's specified limits or
which results in any damage to the engine
(C) Does not hinder or detract from the
vehicle or equipment's ability to perform its normal functions
(D) Is physically intact and well mounted
with no signs of leakage or other visibly detectable
problems
(2) To determine
whether additional emission control groups require separate field
demonstrations, the Executive Officer may consider all relevant information,
including, but not limited to existing field experience and engineering
justification and analysis.
(3)
Industrial Safety Requirements. The installation of a diesel emission control
strategy on an off-road vehicle or piece of equipment used for a field
demonstration within California must conform to all applicable industrial
safety regulations (California Code of Regulations, Title 8, Division 1,
Chapter 4). If all off-road field demonstrations are conducted outside of
California, at least one must conform to these regulations.
(b) Test Period.
(1) For on- and off-road engines, stationary
engines not used in emergency generators, marine, transport refrigeration unit,
and auxiliary power system engines, a vehicle or piece of equipment must be
operated with the diesel emission control strategy installed for a minimum
period of 200 hours or 10,000 miles, whichever occurs first.
(2) For stationary emergency standby engines,
the emission control system must remain in the field for at least 30 days and
operation must include:
(A) 12 maintenance
runs (allowing for engine cool down between runs), and
(B) a minimum of two separate 4 hour sessions
where the engine is operated under load (allowing engine cool down between
runs).
(c)
Reporting Requirements.
(1) Temperature and
Backpressure Measurement Requirements. For strategies that include exhaust
aftertreatment, engine backpressure, exhaust temperature, and engine speed must
be measured and recorded over the entire demonstration period. The applicant
must propose a measurement and recording protocol for approval by the Executive
Officer. The protocol may include, but is not limited to, measurement and
recording of values once every few seconds, or higher frequency measurement
with recording of averages, minima, and maxima over longer time intervals. The
data must include an accurate date and time stamp that corresponds with periods
of actual engine operation. Data must be submitted electronically in columns as
a spreadsheet or text file or another format approved by the Executive Officer.
Failure to submit in an approved format will terminate the application
process.
(2) NOx Emissions
Measurement Requirements. For strategies that include exhaust aftertreatment to
reduce emissions of NOx, the mass emissions of NOx both upstream and downstream
of the aftertreatment device must be measured and recorded over the entire
demonstration period. The applicant must propose a measurement method for
approval by the Executive Officer. The method may include, but is not limited
to, the use of NOx sensors before and after the device. Measurements of NOx
emissions must occur on at least a 1 Hertz basis. Data must be recorded as
averages over time intervals no greater than 10 seconds. The data must include
an accurate date and time stamp that corresponds with periods of actual engine
operation. Data must be submitted electronically in columns as a text file or
another format approved by the Executive Officer.
(3) Electronic System Codes. Error codes,
fault codes, and high backpressure codes, as defined in the applicants test
plan approval letter, that are generated by a diesel emission control
strategy's electronic control system and/or operational monitoring system
during the field demonstration must be submitted with the date and time each
code occurs.
(4) Third Party
Statement. The applicant must provide a written statement from a third party
approved by the Executive Officer, such as the owner or operator of the vehicle
or equipment used in the field demonstration. The written statement must be
provided at the end of the test period and must describe the following aspects
of the field demonstration: overall performance of the test application and the
diesel emission control strategy, maintenance performed, problems encountered,
and any other relevant information. The results of a visual inspection
conducted by the third party at the end of the demonstration period must also
be described. The description should comment on whether the diesel emission
control strategy is physically intact, securely mounted, leaking any fluids,
and should include any other evaluative observations. The third party statement
must clearly identify the demonstration engine and vehicle or equipment using a
unique identifier such as a vehicle identification number and engine serial
number along with the engine family name, and must provide the name and contact
information of the third party.
(5)
Photographic Documentation. For each field demonstration, the applicant must
submit digital photographs in electronic format of the following:
(A) The vehicle or piece of equipment before
installation of the diesel emission control strategy. Photographs must show:
1. The entire vehicle or piece of
equipment.
2. A close-up of the
location in which the diesel emission control strategy will be
installed.
3. All available vehicle
or equipment identification including the make, model, license plate, and
vehicle number.
4. All available
engine identification including the make, model, and engine
label.
(B) The vehicle or
piece of equipment after installation of the diesel emission control strategy.
Photographs must show:
1. The entire vehicle
or piece of equipment showing the diesel emission control strategy installed,
if possible.
2. A close-up of the
installed diesel emission control strategy.
3. All available diesel emission control
strategy identification including labels and logos.
(C) For a filter-based diesel emission
control strategy, the outlet face of the filter after completing the field
demonstration.
(d) Failure During the Field Demonstration.
If the diesel emission control strategy fails, requires repair or maintenance,
suffers any type of component failure, or the demonstration is aborted at any
point in the course of the field demonstration, the applicant must submit a
report explaining the circumstances within 45 days of the occurrence. The
Executive Officer may then determine whether to deny verification or allow the
applicant to correct the failed diesel emission control strategy and either
continue the field demonstration or begin a new field demonstration.
