The identification of any potential CO hotspots, <br /> 3. The District uses the URBEMIS3 modeling program (as developed by the California Air <br /> Resources Board) to calculate the pollutant emissions resulting from various land uses due to <br /> motor vehicle trips. Emissions are calculated for total organic gases (TOG), carbon monoxide <br /> (CO), nitrogen oxide (NOx), and particulate matter of size 10 microns (PM 10) or less in size. <br /> For the purpose of estimating ozone precursor emissions,TOG should be converted to reactive <br /> organic compounds (ROG) by multiplying the TOG emissions by 0.9178. We recommend that <br /> URBEMIS3 be used in the EIR. The results from Urbemis3 should be expressed in pounds per <br /> day. The variables used in the analysis for Urbemis3 should be listed. Various types of land <br /> uses that are identified as future developments should utilize the ITE handbook which should <br /> produce the emissions factors necessary in calculating the pollutant emissions from the <br /> various types of land uses. <br /> 4. The ITE Handbook authored by the Institute of Transportation Engineers is a guide by <br /> which the amount of trip generations derived from the various land uses can be determined. <br /> This guide is a method of determining the emissions factors that results from various types <br /> of land uses associated with the proposed project. <br /> 5. The use of the Caline 4 (available from the California Air Resources Board) computer <br /> program should be used for predicting carbon monoxide, nitrogen dioxide, particulate matter <br /> or other inert gaseous pollutant concentrations near a roadway. <br /> 6. In the development of gasoline storage and dispensing facilities the applicant shall apply <br /> for an Authority to Construct and Permit to Operate pursuant to the District's Rules and <br /> Regulations. It is the applicant's responsibility to be in compliance with District's Rules and <br /> Regulations prior to operation. <br /> The District appreciates the opportunity to comment on this project.
