RESOLUTION NO. 14596 <br /> <br /> A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF <br /> RIVERSIDE, CALIFORNIA, ADOPTING A POI,ICY IN <br /> 3 OPPOSITION TO TRE PROPOSED DEEMPH~SIS OF GOVERN- <br /> MRNT CONTROLS ON NITROGEN OXIDE (NOx) EMISSIONS, <br /> STATING THE REASONS THEREFOR AND REQUESTING THE <br /> SUPPORT IN OPPOSITION FROM TSE RIVERSIDE AND <br /> SAN BEPuNARDINO BOARDS OF SUPERVISORS AND THE <br /> CITRUS BELT LEAGUE O~ CALIFOP~NIA CITIES. <br /> 6 <br /> <br /> 7 WHEREAS, Dr. T. Relnsheimer, chairman of the South <br /> <br /> 8 Coast Air Quality Management District, has 6roposed a strategy <br /> <br /> whereby ozone levels are to be reduced through the deemphasis <br /> <br /> ]0 of qovernment controls on nitrogen oxide (NOx) emissions; and <br /> <br /> WHEP~EAS, while the Systems Application Inc. (SAI)Airshed <br />]2 Model may represent the "state of the art" in computer simulation <br />13 of photochemical atmospheric pollution, its use as a tool for <br /> <br />]4 evaluating air quality management strategies requires consideration <br />]5 of the accuracy ]t exhibits when tested against observed <br />16 measured) conditions - Some results of such testing are <br />17 summarized as follows: <br /> <br />]8 - The predicted location and time of maximum ozone <br /> <br /> concentration correspond fairly ~ell with observed <br /> <br />20 oonditions; <br /> <br />2] - The model under-estimates peak ozone in downwind <br /> <br />22 areas (e.g., San Bernardino Valley) by 20% to 30%-- <br /> <br /> a margin of error sufficient to erase the 30% reduction <br />24 of downwind ozone predicted by the model to result <br /> <br /> - The SAI Airshed Model cannot reliably predict (less <br /> <br />27 than 50% error) levels of nitrogen based pollutants; <br />28 - The Model cannot account for the multiple day air <br /> <br /> pollution episodes which are associated with the <br /> <br />30 highest pollutant levels; and <br /> <br /> <br />
