According to the Soil Survey of Anoka County, soils on the site are Rf(Rifle mucky peat), AnA (Anoka loamy fine
<br />sated, 0 to 2 percent slopes), AnB (Anoka loamy fine sand, 2 to 6 percent slopes), AnC (Anoka loamy fine sand, 6
<br />to [2 percent slopes), LnA (Line loamy fine sand, 0 to 4 percent slopes), ZmA (Zimmerman fine sand, 0 to 2
<br />percent slopes), ZmB (Zimmerman fine sand, 2 to 6 percent slopes), ZmD (Zimmerman fine sand, 6 to 12 pement
<br />slopes), and DIA (Dalbo silt loam, 1 to 5 percent slopes). Please see Figure 4 for the soils present on site.
<br />Type D soils (clay loam, silty clay loam, sandy clay, silty clay, or clay) have high runoff potential. They ha~'~ very
<br />Iow infiltration rates when thoroughly wetted and consist chiefly of clay soils with a high swelling potential, soils
<br />with a permanent high water table, soils with a claypan or clay layer at or near the surface, and shallow soils over
<br />nearly impervious material. These soils have a very low rate of water transmission (0 to 0.05 in/hr). Since the rate
<br />of water transmission is low on these soils, there is greatly reduced risk of groundwater contamination from wastes
<br />or chemicals reaching the groundwater.
<br />Type A soils (sand, loamy sand, or sandy loam) have low runoff potential and high infiltration rates even when
<br />thoroughly wetted. They consist chiefly of deep, well to excessively drained sands or gravels and have a high rate
<br />of water transmission (greater than 0.3 in/hr). There is an increased chance of groundwater contamination in these
<br />soils due to the higher rate of water transmission, which occur on a majority of the site, and therefore precautions
<br />should be taken to prevent spills of wastes or chemicals.
<br />
<br />a. Describe types, amounts and compositions of solid or hazardous wastes, including
<br /> solid animal manure, sludg~ and ash, produced during construction and operation.
<br /> Identify method and location of dispOsal. For projects generating municipal solid
<br /> waste, indicate if there is a source separation plan; describe how the project will be
<br /> modified for recycling. If hazardous waste is generated, indicate if there is a
<br /> hazardous waste minimization plan and routine hazardous waste reduction
<br /> assessments.
<br /> Construction acti~ties for this residential development will generate si~ificant w~te. The amo~t of w~te will be
<br /> typical of residential construction projects. The contractor will dispose of~y w~tes generated at the site in an
<br /> approved method. The contractor will be encour~ed to r~cycle cons~uction w~te that c~ be recycled. ~1 b~h
<br /> and tree w~ste generated by construction will be chipped or othemse recycled ~d will not be bmod on site.
<br /> A~cr construction, ~ical residential solid w~te and h~do~ w~tes will be generated. For residential
<br /> properties, solid w~te t~ically includes paper, organics (food w~tes, textiles/clo~es, wood and robber producm),
<br /> yard wmstcs, ine~ solids and ho~ehold h~ardo~ w~tes. The remaining w~tes will include pl~tics, metals, ~d
<br /> glass, and very small percentages of specialized w~tes such ~ ovemized bulky w~tes.
<br /> All solid w~tes ~11 be handled by a City ofR~sey lice~ed solid w~te hauler. Ho~ehold h~do~ w~te
<br /> generated from individual homes in this development can be disposed of at the ~oka Coun~ Homehold
<br /> Hazardo~ W~te Faciliw. The w~te haulers in Ramsey have m~icipal w~te recycling pro~a~. The residenm
<br /> will be encouraged to recycle all m~icipal solid w~tes that can be recycled.
<br />
<br />b. Identify any toxic or hazardous materials to be used or present at the site and identi¢
<br /> measures to bo used to prevent them from contaminatin~ ~roundwater. If the uso of
<br /> toxic or hazardous materials will lead to a regulated waste, discharge or emission,
<br /> discuss any alternatives considered to minimize or eliminate the waste, discharge or
<br /> emission.
<br /> Fuels and oils needed fbr the operation of construction eq~pment will be delivered but not stored on site (see
<br /> below). Building products ~ed for home construction will be treed, stored, and disposed of properly.
<br /> No previous environmental h~ards have been found on site, No~al'~°nstruction and homeho[d hazardo~ w~tes
<br /> are anticipated. Toxic or hazm-dous materials such ~ ~el for construction'equipment and materials ~ed in the
<br /> construction of homes ~aint,;adhesives, staigs, contaminated rags, acids, b~es, herbicides, and pesticides) will
<br /> likely he used during site preparation and h6~e construction. Spills of these materials are not pla~ed, but could
<br /> require notification of the Minnesota DuW Officem if a si~ificant spill occurs. Builders/contractors me responsible
<br /> fbr proper management ~d disposal of any w~t~'~ener~ed during cons~ction and homeo~e~ are responsible
<br /> [br management and disposal therea~er. During construction of the project, any toxic or h~do~ materials will
<br /> be properly used, stored and disposed of when finished. .
