The required length of stow bales should be alculated assuming a flow depth of one foot to <br />allow freeboard and a fattor of safety on permittivity. Designs azsume regular inspections and <br />maintenance. Stnw bales will be placed at appropriate locations to intercept all runoff from the <br />disturbance area. The straw bales will be placed tightly against each other and keyed into the <br />ground. <br />To verify the effectiveness of the straw bales, EFCI will sample runoff from the site. Given, <br />however, that the mine site is inactive, and sampling must occur during or immediately ~ <br />following a storm event, sampling will be limited by practial constrains and may not ocatr <br />immediately. <br />If sampling indicates that the sediment control systems are not effectively treating the runoff, ~ <br />EFCI will revise and upgrade the drainage control system. <br />3.0 SAE REQUEST <br />Given the limited size of the reclaimed disturbance area, the previously discussed sediment <br />control measures which will effectively prevent significant adverse downstream water quality <br />impacts, and the lack of any underground mine water discharge in the area, EFCI respectively <br />requests DMG approval of a small area exemption for this area. <br />• <br />C~ <br />c:t,rvc,~o~~tnt_DOc <br />_....; +ae~m Rtci sed <br />
