item 23 instead of here.) <br /> <br />Temporary noises and odors may occur from operating heavy equipment for construction activities. <br />Noises common to construction will be generated. Equipment will include trucks, backhoes, graders, Compactors, <br />bobcats, cranes, loaders, compressors, and possibly de-watering pumps. Construction activities will be conducted in <br />co~formance with the City's noise ordinance. Equipment used in the daily construction operations w/Il be muffled. <br />Noise from construction activities will be limited to 7 am to 10 pm weekdays, with weekend hours limited to 9 am <br />to 9 pm. <br />Dust will be controlled by periodic cleanup of the construction site and by limiting the amount of soil disturbance <br />at any given time. Dust will also be controlled through the establishment of permanent vegetative cover. <br />Consideration will he given to suppression of airborne dust by application of waterif significant dust generation <br />occurs during site grading. <br />Odors may also be generated from construction equipment exhaust. -_ _ <br />As in any sanitary sewer system, there is.potential for odors, to .form during operation of the proposed systerh. <br />Hydmget~ sulfide has the potential to form in sewage material under anaerobic conditions, and can produce a <br />rotten-egg odorl particularly where flow turbulence releases gas from solution in the wastewater.-The addition of <br />ehemicals to the sanitary system to suppress growth of the odor-causing bacteria is one option if hydrogen sulfide <br />be. comes a problem in the [uture. Filtering air ventilated from the sewer system through a biofilter is another <br />method of controlling odors, as is utilization of packaged carbon filtration systems. <br />Odor problems are not expected to result from the trunk sewer. The project is similar to many in the metropolitan <br />area. It is primarily a gravity system where slopes are mild and turbulence is not expected to be a problem. <br />The nearest sensitive receptors are the residential homes in the nearby existing housing developments. Average <br />expost~re thnes are estimated to be approximately four to eight weeks. <br /> <br />Are any of the following resources on or in proximity-to the site? <br /> <br />If yes, describe the resource and identify any project-related impacts on the resource. <br />Describe any measures to minimize or avoid adverse impacts. <br />Arc hacological, historical or architectural resources.'? [] No <br /> <br /> [] Yes <br /> <br /> No historic properties were identi fled in a search of the Minnesota Archaeological Inventory and Historic <br /> Structures Inventory for the search area requested. Two archaeological sites were identified: Site number <br /> 2 l AN0136, a 2 acre site located in Township 32, Range 25, Section 19, QUarter section E-SW-NW-NE; and Site <br /> number 2IANu, a l0 acre site located in Township 32, Range 25, Section 19, Quarter section SW-SE-NE-SW. <br />Prime ~r unique farmlands or land within an agricultural preserve? [] No <br /> <br /> [] Yes <br /> Thert~ are areas of Dickman sandy loam soils, 0 to 2% slopes (DNA) that are listed on the Anoka Prime and Other <br /> Important Farmland List as a farmland o£ statewide importance.. <br /> <br />Desigmrted parks, recreation areas or trails? [] No · <br /> [] Yes <br /> There are proposed parks and recreational [~acilities owned and operated by the City of Ramsey within the project <br /> area. Although the trunk sewer extension does no~: pass directly through any parks, it may cross areas of existing <br /> and proposed trails. Permanent impacts to these afhenities are not anticipated as the Project will be placed below <br /> grade. However, temporary indirect impacts (such as noise, dust, and general disruption caused by construction <br /> machinery) may occur to users of the facilities during construction of the Project. These impacts are expected to be <br /> <br />-481- <br /> <br /> <br />
