-2- 2. To assure protection of near -by public water intake structures to the extent practicable and prior to initiation of any construction activities within waters of the U.S., you shall notify Mr. Rick Barth, Rifle City Engineer of your construction activity start and end dates. He can be reached at (970) 665 -6559 or by email at: rbarth(airifleco.org. We note your work schedule dates of mid February to April 30, 2012. 3. Temporary coffer dam and diversion channel activity materials can be manipulated by bull- dozer, track hoe or front-end loader equipment until permanent structures (i.e., j- hooks, vanes, toe logs, bank full benches and rip -rap) are installed. Removal of the temporary coffer dam and reshaping the diversion channel and point bar materials (approximately 37,000 ft) will result in this area performing as a floodplain for future high flows. Materials excavated from the river bed associated with the 1,000' x 250' single channel designs submitted (approximately 250,000 ft) will be removed by track hoe and/or front -end loader, transported to an upland location, and prevented from future river recapture. 4. To verify permit compliance with submitted designs and structure locations, prior to initiation of construction activities within waters of the U.S., you shall submit to the Corps, pre - construction site photographs of the project site.

A plan view drawing of the location of the authorized work footprint (as shown on the permit drawings) with an overlay of the work as constructed in the same scale as the attached permit drawings. c. A description and list of all deviations between the work as authorized by this permit and the work as constructed. Clearly indicate on the as -built drawings the location of any deviations that have been listed. 6.
