IMMEDIATE RELEASE December 20, 2002
NEWS FROM: Compliance Enforcement Division
The Nevada Department of
Motor Vehicles' Compliance Enforcement Division will begin enforcing stricter
opacity standards on exhaust from heavy-duty diesel trucks beginning January 1,
2003. The standards apply in all counties to all trucks and buses with a GVWR of
8,500 pounds or greater.
The new limits are more in line with the opacity standards recommended by the EPA and enacted by most neighboring states. The Nevada State Environmental Commission adopted the tiered limits in October but the Department of Motor Vehicles has issued only verbal courtesy warnings to date. The department's goal is voluntary compliance. Fines are waived on a first offense if the vehicle is repaired within 45 days.
Exhaust from trucks with
engines manufactured in 1991 or later must block no more than 40 percent of the
light passing through it. Engines made between 1977 and 1990 are held to a
standard of 55 percent opacity. Engines made between 1970 and 1976 must meet an
opacity standard of 70 percent. Engine families exempted by the California Air
Resources Board are also exempt in Nevada. Previously, all trucks with engines
1977 or newer were held to the 70
The department conducts
random testing at weigh stations and on the road side. While annual testing is
not required for Nevada-based fleets, the department does conduct courtesy
inspections at fleet yards. The department uses equipment which adheres to the
SAE J1667 standard for opacity measurements adjusted to ambient conditions.
