The Texas Emissions Reduction Plan (TERP) was established by the 77th Texas Legislature in 2001, through the enactment of Senate Bill (SB) 5. Legislation defines the program objective to reduce nitrogen oxides (NOx) emissions from older heavy-duty on-road vehicles and non-road equipment by providing grants and rebates for voluntary upgrades and replacements. Lowering NOX emissions from TERP-eligible sources remains a critical strategy for the Texas State Implementation Plan (SIP).
TCEQ recently published and submitted to the Texas Legislature a biennial report on the status of implementing the Texas Emissions Reduction Plan (TERP) which includes information on each program.
The report notes, in sum, since fiscal 2002, the TCEQ has issued over $786 million under the primary TERP emissions reduction grant program, representing a total of 7,335 projects, or 12,672 individual pieces of equipment and/or vehicles. From fiscal 2002 through fiscal 2010, this level of activity represents a projected reduction of 158,072 tons of NOx , or the equivalent average daily reduction of 67.5 tons of NOx per day in 2011.
