The implementation of the proposed Ramsey <br />Town Center project will increase the amount of vehicle -related carbon monoxide <br />emissions. This increase is due to the increase in traffic volume along the Highway 10 <br />corridor. Peak CO emissions were modeled along Highway 10 for the year 2008 (one <br />year after anticipated build -out) under a worst -case (p.m. traffic, no road improvement) <br />scenario. The CO concentrations modeled were less than the state air quality standards of <br />30 ppm for one -hour and 9 ppm for eight -hours. The modeled CO concentrations are <br />summarized in Tables 22.5 and 22.6. <br />Mitigation Element. There are no specific air quality mitigation measures proposed for <br />the Ramsey Town Center Development, because implementation of the project does not <br />22-7 <br />
