21. Traffic <br />Parking spaces added: <br />Up to 12 spaces added for employee parking and potentially 6 spaces for <br />overnight parking for dump trucks <br />Existing spaces (if project involves expansion): <br />None <br />Estimated total average daily traffic generated: <br />During typical operating season (normally April through November), the <br />estimated total daily traffic is anticipated to be 100 truck loads per day (200 truck <br />trips). <br />Estimated maximum peak hour traffic generated and time of occurrence: <br />Peak traffic typically occurs in the morning with up to 15 loads per hour (30 truck <br />trips). <br />Indicate source of trip generation rates used in the estimates. <br />Most trucking will be destined for nearby Gemstone ready-mixed concrete plants. <br />22. Vehicle-related air emissions <br />Estimate the effect of the project's traffic generation on air quality, including <br />carbon monoxide levels. Discuss the effect of traffic improvements or other <br />mitigation measures on air quality impacts. <br />Vehicle-related air emissions are comprised of emissions from employee vehicles, <br />loaders, and excavation equipment. These emissions contain carbon monoxide, <br />hydrocarbons, and particulate matter. The site is not expected to have an adverse <br />impact on air quality. <br />23. Stationary source air emissions <br />Describe the type, sources, quantities and compositions of any emissions from. <br />stationary sources of air emissions such as boilers, exhaust stacks or fugitive dust <br />sources. Include any hazardous air pollutants (consult EAW Guidelines for a listing) <br />and any greenhouse gases (such as carbon dioxide, methane, nitrous oxide) and <br />ozone-depleting chemicals (chloro-fluorocarbons, hydrofluorocarbons, <br />perfluorocarbons or sulfur hexafluoride). Also describe any proposed pollution <br />prevention techniques and proposed air pollution control devices. Describe the <br />impacts on air quality. <br />The crushing plant will create air emissions from both the generator required to <br />power the crushing plant and from the crushing activity itself. An air emissions <br />permit will be obtained for operation of the processing equipment. The wash <br />plant will also create emissions from the generator used to power the plant. The <br />process of washing the aggregates does not produce dust. The site will generate <br />-11- <br />
