Delta Brick & Climate Company PO Box 280 Paonia, CO 81428 deltabrick.com Christopher Caskey Founder Delta Brick & Climate Company 720-421-2633 chris(@deltabrick.com U.S. Bureau of Reclamation Western Colorado Area Office 445 West Gunnison Ave., Suite 221 Grand Junction, CO 81501-5711 September 23, 2019 Dear Reclamation Staff, Please see attached Use Authorization Form 7-2540. This letter provides additional detail for my application. Delta Brick & Climate Company (DBCC), would like to remove sediment from Paonia Reservoir for use as feedstock in ceramics manufacturing. The location of the proposed activity is the north (upstream) end of Paonia Reservoir, between the boat ramp and Williams Creek. 6th Meridian, Section 33, Township 12 South, Range 89 West. The sediment is primarily the alluvium of Muddy Creek and is composed of gravel, sand, silt, and clay. In 2019, we intend to use an excavator and one or more dump trucks to remove up to 200 cubic yards of sediment. Our target material is silt and clay, which settles out in layers separate from sand and gravel. Prior to excavating, we intend to locate sufficient silt and clay layers on the alluvium surface by hand-digging holes and cores. A broad, shallow excavation will follow. Sand and gravel may be harvested as well. Figure 1 shows the approximate boundaries of our work. Fewer than 10 people will work on site at any one time. The likely number is 2 to 5. Excavating and hauling of sediment will be contracted to a third party. This permit requests access to the reservoir for the remainder of 2019 and most of 2020. Activity will likely be restricted to a few days in the fall and a few days in the spring. The facilities at Paonia State Park will provide adequate sanitation. We intend to film and photograph the permitted activities for our records and for commercial use. This work requires a 110c permit for Colorado Division of Reclamation Mining and Safety. That process is underway. This work does not require a permit from the Army Corps of Engineers.
