California Senate Bill 529 requires the California Environmental Policy Council to identify <strong>and</strong> evaluate all significant<br />
beneficial <strong>and</strong> adverse impacts on the environment that may result from any fuel specification proposed or established by the<br />
California Air Resources Board (CARB); this requirement includes impacts associated with the production, use, <strong>and</strong> disposal<br />
of the compound or compounds that may be used to meet the fuel specification. Additionally, California Senate Bill 989<br />
prohibits the CARB from adopting new fuel specifications until a ‘multimedia’ evaluation has been performed <strong>and</strong> submitted<br />
to the California Environmental Policy Council for final review <strong>and</strong> approval. The California State Water Resources Control<br />
Board (SWRCB) is concerned with the lifecycle impacts that any new fuels may have on, <strong>and</strong> beneficial uses of, surface water<br />
<strong>and</strong> groundwater in California. In the case of PuriNOx, the SWRCB needs information that will allow an informed decision<br />
to be made regarding the relative risk of PuriNOx to California water resources <strong>and</strong> beneficial uses as compared to ultra-low<br />
sulfur diesel (ULSD). The SWRCB has made a good-faith effort to identify all of the information that may be needed <strong>and</strong> has<br />
provided this guidance to Lubrizol.<br />

Indoor exposure to particles of outdoor origin constitutes an important exposure pathway. We conducted an intensive set<br />
of indoor particle measurements in an unoccupied house under differing operating conditions. Real-time measurements were<br />
conducted both indoors <strong>and</strong> outdoors, including PM2.5 nitrate, sulfate, <strong>and</strong> carbon. Because the time-scale of the fluctuations<br />
in outdoor particle concentrations <strong>and</strong> meteorological conditions are often similar to the time constant for building air<br />
exchange, a steady state concentration may never be reached. The time-series experimental data were used to determine the<br />
effect of changes in air exchange rate <strong>and</strong> indoor/outdoor temperature <strong>and</strong> relative humidity differences on indoor particle<br />
concentrations. A multivariate regression was performed to investigate the difference between measured indoor concentrations<br />
<strong>and</strong> results from a simple time-dependent physical model. Environmental conditions had a significant effect on indoor<br />
concentrations of all three PM2.5 species, but did not explain all of the model variation.<br />

NOx, Fine Particle <strong>and</strong> Toxic Metal Emissions from the Combustion of Sewage Sludge/Coal Mixtures: A Systematic<br />
Assessment<br />
Wendt, J. O. L.; Jan. 2003; 16 pp.; In English<br />
Report No.(s): DE2004-820750; No Copyright; Avail: Department of Energy Information Bridge<br />
This research project focuses on pollutants from the combustion of mixtures of dried municipal sewage sludge (MSS) <strong>and</strong><br />
coal. The objective is to determine the relationship between (1) fraction sludge in the sludge/coal mixture, <strong>and</strong> (2) combustion<br />
