River West Homeowners Association <br />RE: SerFer Pit Letter of Response <br />July 3, 2008 <br />Page 2 of 6 <br />CDPH&E permit includes submitting an Application for Construction Permit and <br />Air Pollutant Emission Notices (APEN). The intent of the CDPH&E and the <br />APEN are to limit pollution in all forms and will restrict the SerFer Pit from <br />endangering users of the new Poudre Trail System. <br />3. Undue noise in the area from crushing operations and heavy equipment backup safety <br />alert audible warning devices. <br />It is unclear what threshold or expectations to which this objector is referring. <br />Connell Resources, Inc. received noise related input from the neighborhood <br />meetings. During the meetings, the operation was described in detail. The <br />operation will meet all noise level limits from the town and the county. <br />Connell Resources, Inc. intends to utilize sound reducing efforts and techniques to <br />attenuate any noise generated on the site. This includes placing the crusher <br />generator in an insulated box and locating the crushing operations in the base of <br />the active portion of the mining pit. Further sound buffering will be provided as a <br />result of stockpiling and maximizing the distance between the crushing operation <br />and the residential area immediately south of the proposed operation <br />4. Increased flooding danger due to modifications to the existing flood plain. Reference the <br />flood in May 1999, when the water was over the banks of the Poudre River, covered <br />County Road 13 and made it impossible to travel. The entire valley looked like a lake. If <br />this happened again, it would cause magnesium chloride and other environmental <br />pollutants from the roads and highways in the area to contaminate the public waterways. <br />our belief that _the- proposed_mining operation _and_subsequent_reclamation will not increase the flood levels on the site. A floodplain study has been <br />completed. Results of the floodplain study have been included in the DRMS and <br />Town of Windsor permit applications. The floodplain study shows no adverse <br />impact to the floodplain will be caused during or after mining. Connell <br />Resources, Inc. will not begin mining activities until all applicable permits are <br />approved. This includes obtaining and adhering to a development permit as <br />required by the Town of Windsor Municipal Code (Title IX Flood Damage; Flood <br />Control; Drainage). <br />Magnesium chloride is commonly used to help with dust suppression. Applying <br />magnesium chloride for dust suppression excludes the magnesium chloride from <br />being defined as a solid waste under the Resource Conservation and Recovery Act <br />(RCRA). Therefore, magnesium chloride cannot be classified as a hazardous <br />waste under RCRA because it is not a solid waste. Magnesium Chloride will not <br />be stored on site.
