A detailed air emission analysis was not completed for this project. According to the Mn/DOT Hotspot Screening Method Flow Chart, the benchmark annual average daily traffic volumes (AADT) would not be reached nor does the proposed development site affect any of the MPCA monitored locations or top seven intersections in the Twin Cities Metropolitan Area. Furthermore, the City of Lino Lakes does not expect the projected average annual daily traffic volume from the study area to increase any particular roadway by 10,000 vehicles per day within a ten year timeframe. 23. Stationary source air emissions. Describe the type, sources, quantities and compositions of any emissions from stationary sources of air emissions such as boilers, exhaust stacks or fugitive dust sources. Include any hazardous air pollutants (consult EAW Guidelines for a listing) and any greenhouse gases (such as carbon dioxide, methane, nitrous oxide) and ozone - depleting chemicals (chloro- fluorocarbons, hydrofluorocarbons, perfluorocarbons or sulfur hexafluoride). Also describe any proposed pollution prevention techniques and proposed air pollution control devices. Describe the impacts on air quality. None. 24. Odors, noise and dust. Will the project generate odors, noise or dust during construction or during operation? X Yes _ No If yes, describe sources, characteristics, duration, quantities or intensity and any proposed measures to mitigate adverse impacts. Also identify locations of nearby sensitive receptors and estimate impacts on them. Discuss potential impacts on human health or quality of life. (Note: fugitive dust generated by operations may be discussed at item 23 instead of here.) Construction related impacts such as dust, odors and noise have been considered. Some air pollution is expected to be generated during times of construction. These temporary impacts will be present only during construction. The only existing receptors that could experience impacts are those residences located immediately east of the site. Temporary construction impacts to these receptors are anticipated to be minimal. Following the complete build -out of site, air pollution will be generated by traffic moving along the local and regional street system. Dust is expected to be generated by on -site construction equipment during times of construction. Dust generation will be minimized by enforcing best management practices during construction along with any other applicable permits required by the City of Lino Lakes. Practices that may be enforced include: 1) minimizing the periods and extent of areas being exposed or graded; 2) watering construction areas and haul roads during periods of high winds or high levels of construction activity; 3) minimizing the use of vehicles on unpaved surfaces; and 4) covering and/or spraying material piles and truck loads. No substantial odor sources are expected within the proposed development site. The only sensitive noise receptors near the study area are existing residential properties located east of the proposed development site. While the proximity of these existing residences to the proposed site could be cause for concern, the associated increases in traffic volumes are not anticipated to cause a substantial change in noise levels. Traffic noise increases must be 3 decibels or greater in order to be detectable by the average human ear. A 3- decibel increase occurs when traffic volumes approximately double (100 percent increase). Because the traffic generated by the development would increase traffic volumes on Lake Drive (CSAH 23) by less than 10 percent, no discernible increase in noise would result.
