Current through Register 2024 Notice Reg. No. 38, September 20, 2024

(a) Fuel and Oil Requirements. The applicant must specify the fuel and lubricating oil requirements necessary for proper functioning of the LSI retrofit emission control system. The applicant must also specify any consequences that will result from failure to comply with these requirements, as well as methods for reversing any negative consequences.

(b) Maintenance Requirements. The applicant must identify all normal maintenance requirements for the LSI retrofit emission control system and specify the recommended intervals for cleaning and/or replacing components. Components to be replaced within the defects warranty period must be included with the original LSI retrofit emission control system package or provided free of charge to the customer at the appropriate maintenance intervals. Any normal maintenance items that the applicant does not intend to provide free of charge must be approved by the Executive Officer (the applicant is not required to submit cost information for these.)

(1) The applicant must either affix legible and durable labels, or provide such labels to the installer along with instructions on how to affix them, on both the retrofit emission control system and the engine on which the retrofit emission control system is installed, except as noted in (3) below. The required labels must identify the name, address, and phone number of the manufacturer, the LSI retrofit emission control group name (defined in (2) below), a unique serial number for the LSI retrofit emission control system and the month and year of manufacture. The month and year of manufacture are not required on the label if this information can be readily obtained from the applicant by reference to the serial number. A scale drawing of a sample label must be submitted with the verification application. Unless an alternative is approved by the Executive Officer, the label information must be in the following format:

Name, Address, and Phone Number of Manufacturer

LSI Retrofit Emission Control Group Name

Product Serial Number

ZZ-ZZ (Month and Year of manufacture, e.g., 11-05)

(2) LSI Retrofit Emission Control Group Name. Each LSI retrofit emission control system shall be assigned a name defined as below:

CA/V/MMM/LL##/NHP## or NHL##/APP/XXXXX

Where:

CA: Designates an LSI retrofit emission control system verified in California

V: Year of verification

MMM: Manufacturer code (assigned by the Executive Officer)

LL##: Verified LSI Level (e.g., LL2 means the retrofit system was verified to the "LSI Level 2", LL3a means the retrofit system was verified to "LSI Level 3a).

NHP##: Verified HC + NOx reduction percent (e.g., NH75 means HC + NOx reduction of 75 percent).

NHL##: Verified HC + NOx absolute emissions in units of g/kW-hr, (e.g., NH4.0 means verified HC + NOx emission level of 4.0 g/kW-hr).

APP: Verified application includes a combination of Off-road (OF), or Stationary (ST)

XXXXX: Five alphanumeric character code issued by the Executive Officer

(3) The applicant may request that the Executive Officer approve an alternative label. In reviewing this request, the Executive Officer may consider all relevant information including, but not limited to, the informational content of an alternative label as proposed by the applicant.

(d) Additional Information. The Executive Officer may require the applicant to provide additional information about the LSI retrofit emission control system or its implementation when such information is needed to assess environmental impacts associated with its use.

(e) Owner's Manual. The applicant must provide a copy of the LSI retrofit emission control system owner's manual, which must clearly specify at least the following information:

Warranty statement including the warranty period over which the applicant is liable for any defects.

Installation procedure and maintenance requirements for the LSI retrofit emission control system.

Fuel consumption improvement or penalty, if any.

Fuel requirements, if any.

Requirements for lubrication oil quality and maximum lubrication oil consumption rate

Contact information for replacement components and cleaning agents.

Maintenance Requirements

(f) Noise Level Control. Applicants must ensure that the LSI retrofit emission control system complies with all applicable local government requirements for noise control.

(g) Limit on CO. In order for an LSI retrofit emission control system to be verified, it must comply with one of the following two limits on CO:

(1) For an LSI retrofit emission control system designed to be installed in a certified engine, the system must not increase the emissions of CO greater than the CO emission standards for new, emission-certified, off-road LSI engines adopted by the Air Resources Board and in effect for the model year in which the engine certification was issued;

(2) For an LSI retrofit system designed to be installed in an engine that is not emission-certified, the system must not cause the CO emission level to exceed the greater of 37 g/bhp-hr or ten percent above the engine's baseline CO emission level as determined in accordance with sections 2783 and 2784.

(h) Emission Sampling Ports. To facilitate in-field and normal maintenance diagnostic emission measurements, the applicant may choose to design the LSI retrofit emission control system to have a minimum of two sampling ports where emissions measurements could be made. Guideline suggestions for the sampling port criteria are presented here:

(1) The sampling ports are to be designed to allow for measurements of uncontrolled, engine-out emissions and controlled, tailpipe emissions;

(2) The sampling ports are to be 1/4 inch NPT half couplings, either welded to the exhaust system, or manufactured into the retrofit emission control device where possible;

(3) The sampling port to be used for measuring uncontrolled, engine-out emissions is to be located in a straight section of the exhaust pipe upstream from the retrofit emission control device, after the turbocharger, if so equipped, with a minimum of one to two pipe diameters from any elbows upstream of the sampling port. It is acceptable to locate the sampling port adjacent to the oxygen sensor threaded port, if so equipped;

(4) The sampling port to be used for measuring controlled, tailpipe emissions is to be placed on the muffler body, after the catalyst, if so equipped, or if in the exhaust pipe, should be located a minimum distance of 10 inches from the tailpipe opening, if feasible, otherwise, it should be located as far as possible from the tailpipe opening;

(5) The locations of the sampling ports are to be designed to be accessible to test personnel without removing major engine or equipment components, such as the forklift counterweight, for example;

(6) The sampling ports are to be equipped with threaded plugs.

(7) If the sampling ports are designed to be installed by the retrofit system installer, the applicant must provide all necessary parts and complete instructions for proper installation;
