The bed and bank disturbance <br />is calculated by estimating the wetted perimeter of the ephemeral channels during normal high flow <br />and multiplying that value by the length of channel disturbed. The estimated bed and bank <br />disturbance is 1.42 acres (4100' X ISL. Through a separate action by letter dated November 8, 1996, <br />the Corps approved the construction of two sediment ponds at the Bowie No. 2 Mine which will <br />disturb an additiona10.15 acres of bed and bank. <br />The drainage from the ephemeral channels will be routed around and through the access road and <br />mine benches with culverts and riprap diversion channels. The enclosed Plan View shows the <br />proposed drainage channel disturbance and locations where culverts and riprap channels will be used <br />to mitigate the disturbance. <br />Approximately 0.31 acres of wetlands will be disturbed. The enclosed Plan View shows the outline <br />of the existing wetland areas as well as the proposed wetland disturbance. Bowie Resources Limited <br />proposes to mitigate the loss of the wetlands by constructing and planting wetlands at strategic areas <br />between sediment Pond C and the lower limit of the drainage channel disturbance. The riprap <br />channels and culverts to be placed in the upper reaches of the ephemeral channel should help convey <br />• the available spring flow to the lower limits of the drainage channel disturbance, Therefore, water <br />will be available for wetland construction. Equipment will be available to clear brush and place soil <br />to construct the wetlands. <br />
