Further, if an intervenor files comments or documents with the Commission relating to the merits of an issue that may affect the responsibilities of a particular resource agency, they must also serve a copy of the document on that resource agency.

k.Description of Application:The exemptee proposes to install a pneumatic crest gate system on 140 feet of the existing 178-foot-long spillway at the Jackson Mills Project to alleviate upstream flooding. The pneumatic crest gate system will consist of 6-foot-high, 20-foot-long, hinged steel panel sections, supported on the downstream side of the dam by tubular, air-filled, rubber bladders. In order to install the pneumatic crest gates, the exemptee will need to modify the existing Jackson Mills Dam by reducing 140 feet of the existing spillway by approximately 6 feet to allow for the installation of the 6-foot-high pneumatic crest gates. Additionally, the exemptee proposes to remove the 38-foot-long section of temporary flashboards located near the fishway.

The proposed pneumatic crest gate system would be designed for flood control purposes, and will not operate at flows below 7,500 to 9,000 cubic feet per second (cfs). The exemptee is not proposing to modify the height of the dam, therefore normal water levels would be maintained at their current elevation, and normal flows upstream and downstream of the project will not be altered upon installation of the crest gate system. The crest gate system would be designed to withstand overtopping in the raised position, and will be capable of operation in both a fully raised and partially raised position.

During construction of the of the pneumatic crest gate system, the exemptee proposes to perform the construction in "dry conditions" by eliminating flows at or over the Jackson Mills Dam by using an existing submerged cofferdam located about 300 feet upstream of the dam to divert all flows through the existing powerhouse, and setting the existing turbine units to sluice mode. Where feasible, the exemptee proposes to relocate fish and amphibian species to avoid possible fish stranding.
