San Diego-Tijuana Diesel Emissions Reduction Project

Location: California: San Diego-Tijuana Border Region

The EPA is providing a $223,918 grant to the San Diego County Air Pollution Control District to evaluate the costs and effectiveness of emission control retrofit technologies on Mexican heavy-duty diesel vehicles operating in the San Diego County-Tijuana border region. Approximately 50 Mexico-domiciled heavy-duty diesel trucks operating in the border region will be retrofitted with diesel oxidation catalysts and crankcase filtration system to demonstrate their viability under Mexican operating conditions.
