It can be seen from the above table that the CO standards are not projected to be exceeded at any of the receptor locations assuming the project to be developed as envisioned, and using the information and methods outlined above. Thus, it is not anticipated that traffic improvements or other mitigation measures will be required to address air quality issues associated with the proposed project. Stationary Source Air Emissions: Will the project involve any stationary sources of air emissions (Such as boilers or exhaust stacks)? Yes No If yes, describe the sources, quantities, and composition of the emissions; the proposed air pollution control devises; the quantities and composition of the emissions after treatment; and the effects on air quality. The project will involve installation of small, natural gas-fired space heating devices in new buildings. Natural gas-fired space heaters exhaust small amounts of PM, NOx, CO, and HC. These space-heating devices are not expected to adversely affect air quality in the area. 25. Will the project generate dust, odors, or noise during construction and lor operation? Yes No 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. The project will not generate significant odors. The proposed development has the potential to generate noise from two types of sources: · Construction activities; · Additional traffic generated by the development. Significant noise impacts occur when: · Noise levels increase by ~ 3 decibels (dBA); · Noise levels exceed state standards. There are two descriptors for state noise standards: · L 1 0 - the 90th percentile, in which noise levels are exceeded 10 percent of the time. · L50 - the 50th percentile, in which noise levels are exceeded 50 percent of the time.
