Surface coating facilities are major sources of volatile organic compounds (VOCs) in urban areas. These VOCs can
contribute to ground-level ozone formation, and many are hazardous air pollutants (HAPs), including xylene, ethylbenzene, and toluene. This project was conducted in order to provide information for updating the Texas Commission on
Environmental Quality (TCEQ), USA, permit by rule for Surface Coating Facilities. Project objectives were: 1) To develop a database of information regarding surface coating facilities in Texas; 2) To estimate maximum emission rates
for various VOC species from surface coating facilities in Texas; 3) To conduct dispersion modeling to estimate off-site
impacts from surface coating facilities. The database was developed using 286 TCEQ permit files authorizing surface
coating facilities in Texas during 2006 and 2007. The database was designed to include information important for estimating emission rates, and for using as inputs to the dispersion model. Hourly and annual emissions of volatile organic
compounds (VOCs), particulate matter (PM), and exempt solvents (ES) were calculated for each permitted entity/
company in the database, according to equations given by TCEQ. Dispersion modeling was then conducted for 3 facility configurations (worst-case stack height, good practice stack height, and fugitive emissions), for urban and rural dispersion parameters, for 8-hour and 24-hour operating scenarios, and for 1-hour, 24-hour, and annual averaging times,
for a total of 36 scenarios. The highest modeled concentrations were for the worst-case stack height, rural dispersion
parameters, 24-hour operation scenario, and 1-hour averaging time. 108 specific chemical species, which are components of surface coatings, were identified as candidates for further health impacts review.

Biodiesel has generated increased interest recently as an alternative to petroleum-derived diesel. Due to its high oxygen
content, biodiesel typically burns more completely than petroleum diesel, and thus has lower emissions of hydrocarbons
(HC), carbon monoxide (CO), and particulate matter (PM). However, biodiesel may increase or decrease nitrogen oxide
(NOx) and carbon dioxide (CO2) emissions, depending on biodiesel feedstock, engine type, and test cycle. The purpose
of this study was to compare emissions from 20% blends of biodiesel made from 4 feedstocks (soybean oil, canola oil,
waste cooking oil, and animal fat) with emissions from ultra low sulfur diesel (ULSD). Emissions of NOx and CO2 were
made under real-world driving conditions using a Horiba On-Board Measurement System OBS-1300 on a highway
route and arterial route; emissions of NOx, CO2, HC, CO, and PM were measured in a controlled setting using a chassis
dynamometer with Urban Dynamometer Drive Schedule. Dynamometer test results showed statistically significant
lower emissions of HC, CO, and PM from all B20 blends compared to ULSD. For CO2, both on-road testing (arterial,
highway, and idling) and dynamometer testing showed no statistically significant difference in emissions among the
B20 blends and ULSD. For NOx, dynamometer testing showed only B20 from soybean oil to have statistically significant higher emissions. This is generally consistent with the on-road testing, which showed no statistically significant
difference in NOx emissions between ULSD and the B20 blends.; Biodiesel has generated increased interest recently as an alternative to petroleum-derived diesel. Due to its high oxygen
