Title: Improvement of emissions inventories for industrial coatings and thinning and cleanup solvents.

Principal Investigator / Author(s): Rogozen, Michael B

Contractor: Mactec/Harding, ESE, Inc

Contract Number: 00-314


Research Program Area: Emissions Monitoring & Control

Topic Areas: Stationary Sources


Abstract:

Much of the current emission inventory for industrial coatings and associated thinners and cleanup solvents, as well as for thinners and cleanup solvents associated with architectural and industrial maintenance (AIM) coatings, is outdated or based upon undocumented assumptions. To improve the inventory, we surveyed industrial coating manufacturers, users of industrial coatings, commercial painters and homeowners who did their own house painting. From the survey findings, we developed new emission factors and speciation profiles, and established several new factors for relating solvent use to coating use. Using our results in conjunction with the ARB's 2001 architectural coatings survey, we developed estimates of solvent use by county and air basin, and total organic gas (TOG) and reactive organic gas (ROG) emissions by county, air basin, and air pollution control district. Our thinning and cleanup solvent emissions estimates are higher than stated in the current inventory for architectural and industrial maintenance coating use. We developed growth factors to project architectural coating and solvent emissions. Finally, we identified data sources, software, and an algorithm for allocating county AIM coatings to grid squares, using census block population and numbers of owner-occupied households as surrogate variables.
