Effect of and Alternatives to Restricting Operation of Construction Equipment toImprove Regional Air Quality

摘要

Texas National Resource Conservation Commission (TNRCC) rules, now withdrawn,were to affect Texas Department of Transportation (TxDOT) by placing restrictions on construction equipment activity. One rule, which was to become effective in 2005, sought to reduce ozone formation by limiting the amount of oxides of nitrogen (NO-x) produced by heavy-duty diesel equipment in the early morning hours. This project reviewed TNRCC's analysis, evaluated potential project cost and schedule impacts, assessed alternative emission control technologies, and evaluated the impacts of work zone lane closures for on-road emissions.
