SOUTH COAST AIR QUALITY MANAGEMENT DISTRICT

RULE 1605 - CREDITS FOR THE VOLUNTARY REPAIR OF ON-ROAD MOTOR VEHICLES IDENTIFIED THROUGH REMOTE SENSING DEVICES
(Adopted October 11, 1996)

(a) Purpose
The purpose of this rule is to provide opportunities to generate VOC, NOx, and CO mobile source emission reduction credits (MSERCs) that could be used as an alternative means of compliance with District regulations. These credits would be generated based on voluntary emission reductions created by reducing the emissions of high-emitting vehicles through the repair of emissions related components. High-emitting vehicles would be identified through the use of remote sensing devices (RSDs). MSERCs would be based on emission reductions that are surplus to local, state, and federal emission reduction requirements, including the State’s Motor Vehicle Inspection Program and Accelerated Vehicle Retirement Program.

(b) Applicability
This voluntary rule is inoperative 60 days subsequent to a declaration by the Bureau of Automotive Repair (BAR) that the enhanced Inspection and Maintenance Program is operational in the District, and applies to 1966 and newer model-year gasoline-powered passenger cars and light-duty trucks that are registered as operable vehicles in the District by the California Department of Motor Vehicles (DMV).

(d) Rule 1605 MSERC Program Requirements

  1. In order to generate MSERCs, a program operator shall identify and repair high-emitting vehicles as follows:

    (A) The program operator shall use RSDs to initially identify potential high-emitting vehicles using cut points of 4 percent and 0.1 percent for exhaust CO and HC, respectively. The Executive Officer may approve alternative CO and HC cut points provided that data is submitted by the program operator to the District demonstrating that these alternative cut points are at least as effective in identifying high-emitting vehicles compared to cut points of 4 percent and 0.1 percent for exhaust CO and HC, respectively.

    (B) The program operator shall emission test vehicles identified as potential high-emitting vehicles at a Smog Test Station to determine compliance with Motor Vehicle Inspection Program requirements according to BAR90 emission test results. The program operator shall be responsible for obtaining permission to include a vehicle in the program from the vehicle owner. The program operator shall ensure that:

    (i) the vehicle engine is at its normal operating temperature (i.e., warmed-up) at the beginning of the emission test.

    (ii) the vehicle does not use accessory equipment which would result in an additional load on the vehicle’s engine during the BAR90 emission test, such as the use of air conditioning.

    (iii) the BAR90 emission test is conducted by a person authorized by BAR to conduct such tests.

    (iv) the emission test procedure includes BAR90 exhaust emission testing and all other procedures specified by BAR to determine compliance with Motor Vehicle Inspection Program requirements.

    (v) the initial pre-repair BAR90 emission test is conducted on the vehicle as received, without any adjustments or modifications to the vehicle that could affect its emissions prior to performing the smog check. The initial pre-repair emission test shall be conducted with the BAR90 test equipment in manual mode (i.e., without electronic notification of test results to BAR).

    (C) The program operator shall only identify vehicles failing BAR90 2500 rpm emission testing as high-emitting vehicles, and such vehicles shall be eligible for MSERC generation.

    (D) The program operator shall ensure the vehicle repairs performed under a Rule 1605 MSERC Program are conducted only by person(s) permitted by BAR to conduct vehicle repairs under the Motor Vehicle Inspection Program. Repairs shall include all procedures necessary to bring the vehicle into compliance with Motor Vehicle Inspection Program requirements.

    (E) The program operator shall have the vehicle retested subsequent to repairs for compliance with Motor Vehicle Inspection Program requirements. The post-repair emission test shall be conducted with the BAR90 test equipment in certification mode (i.e., with electronic notification of test results to BAR).

  2. The program operator shall not include any gasoline-powered passenger cars and light-duty trucks in the program for MSERC generation if one or more of the following occur:

    (A) A smog check has yet to be conducted as required by law or the owner has been notified that a smog check is required as part of the DMV registration renewal process.

    (B) The vehicle is scheduled to be smog checked due to DMV registration renewal requirements, within a three month period subsequent to its identification as a potential high-emitting vehicle.

    (C) The vehicle will be scrapped or retired as part of a local or statewide vehicle scrapping program.

  3. For Rule 1605 MSERC programs that utilize more than 10 smog test stations, program operators shall submit notice to the Executive Officer at least one week prior to emission testing and repairing vehicles at smog test stations, pursuant to paragraph (d)(1), indicating specific locations, dates, and times for emission testing and repair activities. The notice may be submitted either in writing or electronically. For Rule 1605 MSERC programs that utilize 10 or fewer smog test stations, the smog test facility or the program operator shall provide the Executive Officer with the projected number of vehicles to be emission tested or repaired for a specific day upon request at any time during that specific day.
  4. Program operators shall comply with all applicable regulations and obtain all necessary permits from applicable agencies with regard to conducting RSD measurements on public roads, and identifying and contacting vehicle owners.

(e) Issuance of MSERCs

  1. Rule 1605 Project Plan
    At least one month prior to initial implementation of a Rule 1605 remote sensing/vehicle repair project, the Program Operator shall submit a Rule 1605 Project Plan. The Rule 1605 Project Plan shall contain the following specific information:

    (A) description of RSD equipment, including HC, CO and NOx (if available) cut points to be used to identify potential high-emitting vehicles pursuant to subparagraph (d)(1)(A);

    (B) proposed RSD test locations and site configurations; and

    (C) identification of Smog Test Station(s) to be used to test and repair high-emitting vehicles and proof of BAR certification.

  2. To be eligible for MSERC generation, the Rule 1605 Project Plan must be approved by the Executive Officer prior to implementation of the project.
  3. Rule 1605 MSERC Application
    In order to generate MSERCs, the Program Operator shall submit a Rule 1605 MSERC Application for MSERCs for a vehicle not later than 6 months after a vehicle has been identified for inclusion in the program. The purpose of the Application is to document the identification and repair (if applicable) of all vehicles identified as high-emitting vehicles. The Application shall include at a minimum:
