November Question of the Month

Question of the Month: Which states have adopted the California Air Resources Board (CARB) aftermarket conversion certification requirements?
Answer: In the United States, all aftermarket conversion systems (except pure battery electric vehicles) must meet current applicable U.S. Environmental Protection Agency (EPA) standards. EPA instituted these standards to assure that a vehicle’s tailpipe emissions do not increase as a result of the conversion. For more information on EPA standards for vehicle and engine conversions, please refer to the EPA Alternative Fuel Conversion website (http://epa.gov/otaq/consumer/fuels/altfuels/altfuels.htm).
CARB has set its own standards for alternative fuel conversion systems, which are more stringent than those of EPA. Manufacturers that wish to sell aftermarket conversion systems for use in California must meet CARB standards and obtain approval from CARB. While EPA accepts all CARB certifications to meet their standards, EPA certificates of conformity and tampering exemptions are not required by CARB and cannot take the place of CARB certification.
In addition to impacting the sale and use of aftermarket conversion systems in California, the CARB conversion standards also impact some of the 13 other states that have adopted CARB’s overall motor vehicle emissions regulations. The table below shows the states that have adopted CARB’s vehicle emissions standards in whole or in part. It also indicates whether each state enforces EPA or CARB aftermarket conversion standards.

  2. Many of the older properties in London and even some of the newer ones are prone to drainage problems. With everything from root growing into pipes, your own home waste blocking the pipe, to leaves and gravel being washed into the storm drains, there are a million and one things that can cause pipes inside and outside your home to be blocked.........
