Emission Standards:
1. New Snowmobiles: All new snowmobiles sold in California must meet the state's emission standards. These standards are designed to limit the emission of pollutants such as hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx) from snowmobile engines.
2. Emission Control Systems: Snowmobiles must be equipped with emission control systems, such as catalytic converters, to reduce pollutants. These systems must be maintained in proper working condition.
3. Exhaust Systems: Snowmobiles must have properly functioning exhaust systems that direct emissions away from the rider.
4. Tampering: It is illegal to tamper with or modify the snowmobile's emission control systems or exhaust systems in a manner that increases emissions.
Noise Standards:
1. Noise Limits: Snowmobiles must meet specific noise level limits to mitigate noise pollution. The maximum allowable noise level varies depending on the type of snowmobile and the testing procedure used.
2. Mufflers: All snowmobiles must be equipped with properly functioning mufflers to reduce noise. Modifying or removing mufflers to increase noise levels is prohibited.
Other Requirements:
1. Spark Arrestors: Snowmobiles must be equipped with spark arrestors to prevent the emission of hot particles and sparks that could start wildfires.
2. Visual Inspection: Law enforcement officers or authorized personnel may conduct visual inspections of snowmobiles to ensure compliance with emission and noise regulations.
3. Reporting Requirements: Manufacturers must submit annual reports to the California Air Resources Board (CARB) detailing the emission control systems and noise control systems used in their snowmobiles.
It is important to note that these regulations may be updated or amended over time, so it's recommended to refer to the latest version of the California Code of Regulations for the most current requirements. Additionally, some local jurisdictions may have additional regulations and ordinances related to snowmobile use and emissions.
