Amendments to Smoke Inspection Programs

This page last reviewed April 12, 2018


Background

The Heavy-Duty Vehicle Inspection Program (HDVIP) and Periodic Smoke Inspection Program (PSIP), which began over two decades ago, are ARB's existing heavy-duty vehicle screening programs to detect potentially high-emitting in-use trucks and buses. These programs have been highly effective in identifying tampered heavy-duty vehicles and those with excessive smoke emissions. Since that time, CARB has adopted more stringent emission standards, and in-use rules that effectively require the use of exhaust aftertreatment, such as diesel particulate filters (DPFs) and selective catalytic reduction systems. In addition, on-board diagnostics (OBD) systems, which monitor engine and emission control systems performance, were fully required for on-road heavy-duty engines beginning with the 2013 model year. Amendments to the HDVIP and PSIP program which would require trucks to meet more stringent opacity limits, appropriate to today's modern trucks, are proposed. This webpage details ARB's activities related to potential regulatory revisions on the HDVIP and PSIP to reduce the opacity threshold.

On February 28, 2017, ARB staff will conduct a public workshop in Diamond Bar at the office of the South Coast Air Quality Management District to discuss potential regulatory changes to the ARB's HDVIP and PSIP. Staff also will briefly discuss progress toward developing a comprehensive inspection and maintenance program for heavy-duty diesel vehicles (HD I/M program) with a gross vehicle weight rating over 14,000 pounds, which is planned for implementation in the post-2020 timeframe. Earlier workshops were held on August 25, 2016, and September 9, 2016, in El Monte and Sacramento, respectively. Please see the workshop notice for more details.
