Watershed Permit Specific Information As stated in Section 10.05.010 (Intent of City Watershed District) of the RMC, "...The District and these regulations are created only for the purpose of protecting the City's waterworks and water supply, and not for the purpose of regulating land use activities, which activities shall continue to be regulated by Garfield County, the federal government, and any other authority with jurisdiction over land use activities within the District..." The jurisdiction of the City Watershed District spans only permitting of activities based on the risk of injury to the City's Waterworks and Pollution of the City's Water Supply. Therefore, we will directly address these two issues in this section of the Watershed Permit Addendum. Possible Risks to the City's Waterworks The City of Rifle's water intake structure lies approximately one mile from the nearest edge of the pit excavation. The only foreseeable damage to the structure would be natural migration of the river channel. Throughout the life of a river, the primary channel will migrate. While the meandering of a river's alignment is a natural process, the alignment can be influenced by man- made interaction. The mining and reclamation plans for Glen's Pit have been designed to minimize the risk of influencing the deviation of the river. All excavations occur outside the 100-year floodplain removing the concern of pit capture during high water events. A culvert will also be installed outside the 100-year floodplain to allow floodwaters which exceed the 100-year floodplain to slowly interact with the reclaimed lake rather than overtopping the bank. The threat of lateral channel migration capturing the pit is very minimal. The excavation limits are at least 100 feet from the nearest minor channel and more than 500 feet from the main channel of the river. To further minimize the risk of channel migration causing pit capture, the operator (during mining) or the landowner (after mining) commits to bank stabilization in the event channel migration significantly reduces the 100-foot buffer between the excavation and the nearest river channel. While a statement of no risk cannot be made for this site, it can easily be seen that the site poses a very limited risk to the City's Waterworks. Therefore, we request that this application be reviewed as a minor impact. Possible Risks of Pollution to the City's Water Supply Due to location, the site will interact with the watershed of the City of Rifle. The site will have a discharge point as seen on the CDMG Permit Application. This discharge point falls under the jurisdiction of the Colorado Department of Health Water Control Division.
