Riverstone South EAW <br />Draft — December 2020 <br />c. Project related use/storage of hazardous materials - Describe chemicals/hazardous materials used/stored <br />during construction and/or operation of the project including method of storage. Indicate the number, <br />location and size of any above or below ground tanks to store petroleum or other materials. Discuss <br />potential environmental effects from accidental spill or release of hazardous materials. Identify measures <br />to avoid, minimize or mitigate adverse effects from the use/storage of chemicals/hazardous materials <br />including source reduction and recycling. Include development of a spill prevention plan. <br />Development of the project area is not expected to generate or require storage of substantial amounts <br />of hazardous wastes or materials. Future residential development is expected to result in the storage <br />or generation of small amounts of typical household cleaners, paints, lubricants, and small engine <br />fuels over time. Petroleum storage tanks and commercial petroleum -based businesses are not <br />proposed in the project area. <br />d. Project related generation/storage of hazardous wastes - Describe hazardous wastes generated/stored <br />during construction and/or operation of the project. Indicate method of disposal. Discuss potential <br />environmental effects from hazardous waste handling, storage, and disposal. Identify measures to avoid, <br />minimize or mitigate adverse effects from the generation/storage of hazardous waste including source <br />reduction and recycling. <br />Normal construction and household hazardous wastes are anticipated. Toxic or hazardous materials <br />such as fuel for construction equipment and materials used in the construction of homes (paint, <br />adhesives, stains, contaminated rags, acids, bases, herbicides, and pesticides) will likely be used <br />during site preparation and home construction. Spills of these materials are not likely to occur, but a <br />substantial spill could require notification of the Minnesota Duty Officer. Contractors and builders <br />will be responsible for proper management and disposal of wastes generated during construction. <br />Homeowners will be responsible for management and disposal of hazardous waste thereafter. <br />Homeowners will be able to dispose of household hazardous waste at the Anoka County Household <br />Hazardous Waste Facility. <br />13. Fish, Wildlife, Plant Communities and Sensitive Ecological Resources (Rare <br />Features) <br />a. Describe fish and wildlife resources as well as habitats and vegetation on or in near the site. <br />Fish and wildlife resources on and near the site are related to the composition, quality, size, and <br />connectivity of plant communities such as cultivated cropland, wetlands, woodlands, and grasslands. <br />Vegetative cover types on the project area were mapped based on aerial photography, the wetland <br />delineation, and field reviews (Figure 6). The project area is about 70% cropland and 3 0% <br />woodland, with less than one acre of grassland. Habitats in the project area are likely used by <br />wildlife adapted to agricultural and suburban environments, such as white-tailed deer, songbirds, <br />small mammals, and amphibians. <br />The project area falls in the Anoka Sandplain Ecological Subsection of the MN DNR Ecological <br />Classification System and the Anoka Sand Plain and Mississippi Valley Outwash of the Level IV <br />Ecoregion of the U.S. EPA. This area consists of a flat, sandy lake plain and terraces along the <br />21 <br />
