May 6, 2015 Page 9 of 1 1 avoid or minimize turbidity �sedimentation while physically altering the water features. Discuss how the project will change the number or type of watercraft on any water body, including current and projected watercraft usage. The project will be provided wifh a defention area that will control fhe rate of runoff as well as provide some degree of wafer treafinent and oil removal. Runoff discharge will be connected to the existing ROSEVILLE storm water sewer system and pre and post-development runoff rates will remain unchanged or reduced. Therefore, effects to existing nearby wetlands are not expected. There will be no effects. Storm water will be diverted to ROSEVILLE's existing storm sewer system. As such, there will be no net increase and/or Direct/Indirect effect to other surface waters. 12BI1. WATER RESOURCES MPCA Comment: See number 1 2 above. ROSEVILLE's Comment: No no response necessary. RAMAKER Comment: Response to this bullet was not required. 13A. CONTAMINATION/HAZARDOUS MATERIALS/WASTES MPCA Comment: The Phase I Environmental Site Assessment completed for this Project states that contaminated soils and groundwater were encountered on the site in relation to releases from three underground storage tanks formally located at the site. Although both leak sites were granted regulatory closure by the MPCA, contaminated soil and�or groundwater may still be present at the site and encountered during construction. The information requested in this section should be included here. ROSEVILLE's Comment: Brief response on what will be done with and remaining hazardous materials if found during construction. RAMAKER Comment: A Maferial Handling Plan will be developed prior to construction. Prior fo development of the plan, additional review of regulatory files regarding the closed LUST incidents, as well as characterization of wastes will be required to determine the appropriate handling of unearthed material during the construction project. The objectives of the additional review, characterization, and Material Handling Plan will be to summarize known contaminants, identified areas of concern with respect to the known contamination, provide an overview of anticipated construction activities, define criteria to identify material types, identify field procedures to segregate materials or on or off-site disposal, and summarize disposal and manifest requirements. All contractors will be required to handle contaminated materials in accordance with the Material Handling Plan. In addition, environmenfal oversight during construcfiion will be implemented fio document handling of material during construction. If required, the Material Handling Plan will be provided to MPCA for approval prior to consfirucfion. 13B. CONTAMINATION/HAZARDOUS MATERIALS/WASTES MPCA Comment: This question addresses the generation�storage of solid wastes, rather than hazardous wastes. The Project will generate solid waste, especially during construction. The information requested in this section should be included here. ROSEVILLE's Comment: Provide a brief response on what will be done with the solid wastes generated during construction. RAMAKER Comment: A Material Handling Plan will be developed prior to construction. Prior to development of the plan, additional review of regulatory files regarding the closed LUST incidenfs, as well as characterizafion of wastes will be required to defiermine the appropriafe handling of unearthed material during the construction project. The objectives of the additional review, characterization, and Material Handling Plan will be to summarize known contaminants, identified areas of concern with respect to the known contamination, provide an overview of anticipated construction activities, define criteria to identify material types, identify field procedures to segregate materials or on or off-site disposal, and summarize disposal and manifest requirements. All contractors will be required to handle contaminated materials in accordance with the Material Handling Plan. In addition, environmental oversight during construction will be implemented to document handling of material during construction. If required, the Material Handling Plan will be provided fo MPCA for approval prior fo consfiruction.
