An air quality analysis was conducted for the indirect source permit application. The analysis was conducted using U.S. Environmental Protection Agency approved models to assess impacts from carbon monoxide (CO) emissions generated by traffic one year after completion of the proposed project. Results of the air quality analysis indicate that after the project is completed, state CO standards will continue to be maintained. The maximum predicted 1- and 8 -hour average CO impacts, including monitored background concentrations, are parts per million (ppm) and ppm, respectively. Further details can be found in Appendix D, the air quality analysis from the Indirect Source Permit application cited above. Report pending. To be provided by PTG 24. Stationary Source Air Emissions: Will the project involve any stationary sources of air emissions (Such as boilers or exhaust stacks)? Stationary sources of air emissions will include only natural gas space heaters. The emissions from these units will not have a significant impact on the ambient air quality. 25. Will the project generate dust, odors, or noise during construction and /or operation? If yes, describe the sources, characteristics, duration, and quantities or intensity, and any proposed measures to mitigate adverse impacts. Also identify the locations of sensitive receptors in the vicinity and estimate the impacts on these receptors. Dust During construction, particular emissions will temporarily increase due to the generation of fugitive dust. The following dust control measures will be undertaken as necessary: 1. Minimize the period and extent of areas being exposed and regarded at any one time. 2. Spraying construction areas and all roads with water, especially during periods of high wind or high levels of construction activity. 3. Minimize the use of vehicles on unpaved surfaces. Odors Covering or spraying material piles and /or truck loads. The project has the potential to generate noise from four types of sources: • construction activities, • additional traffic generated by the project, • loading dock operations, and • roof -top fans.
