Page 38 17. Air a) Stationary source emissions - Describe the type, sources, quantities and compositions of any emissions from stationary sources such as boilers or exhaust stacks. Include any hazardous air pollutants, criteria pollutants. Discuss effects to air quality including any sensitive receptors, human health or applicable regulatory criteria. Include a discussion of any methods used assess the project’s effect on air quality and the results of that assessment. Identify pollution control equipment and other measures that will be taken to avoid, minimize, or mitigate adverse effects from stationary source emissions. The development is not anticipated to include any stationary sources emissions from sources such as boilers or exhaust stacks. Hazardous air pollutants are not anticipated to be generated onsite post-development. New residences are expected to include heating and cooling systems operated by natural gas and electricity, which will be similar to those of other homes in the surrounding area. The emissions produced will be in alignment with the planned future land use outlined in the City’s Comprehensive Plan (Figure 5). b) Vehicle emissions - Describe the effect of the project’s traffic generation on air emissions. Discuss the project’s vehicle-related emissions effect on air quality. Identify measures (e.g. traffic operational improvements, diesel idling minimization plan) that will be taken to minimize or mitigate vehicle-related emissions. Motor vehicle emissions will be generated from vehicles traveling to and from the development site, and from construction equipment to perform the construction activities. Vehicle traffic contributes to an increase in carbon monoxide, carbon dioxide, nitrogen oxides, particulate matter, and ozone. No portion of Sherburne County is identified as a carbon dioxide maintenance area as defined by the U.S. Environmental Protection Agency (U.S. EPA), exceeding the moderate 1971 air quality standard for carbon monoxide (12.7 ppm) (41). No portion of Sherburne County is identified as exceeding the 2012 National Ambient Air Quality Standards (NAAQS) for particulate matter (42), the 1971 NAAQS for nitrogen dioxide (43), or the 2015 NAAQS 8-hour ozone (44). Minor emissions generated from construction equipment will occur during the construction phase. Contractors will be responsible for ensuring equipment is properly maintained and not contributing to excess emissions. c) Dust and odors - Describe sources, characteristics, duration, quantities, and intensity of dust and odors generated during project construction and operation. (Fugitive dust may be discussed under item 17a). Discuss the effect of dust and odors in the vicinity of the project including nearby sensitive receptors and quality of life. Identify measures that will be taken to minimize or mitigate the effects of dust and odors. Dust and odor production during and after development will be consistent with a typical residential/commercial development. During construction, temporary odors from gas machinery
