The greater storms that <br />2 occur on the tailings disposal area will be handled <br />3 because the slope of the tailings disposal area is <br />4 very gentle. It's a 1/2 percent slope coming across <br />5 the area. <br />6 Greater storms will be handled in the <br />7 drainage swales. There are low flow channels and <br />8 then there are drainage swales that are provided as <br />9 part of the post-reclamation contouring. <br />l0 The drainage swales have been designed <br />11 for the 100-year, 24-hour storm, up to ttie probable <br />12 maximum precipitation event, and the spillway has <br />13 been designed to route the probable maximum <br />14 precipitation event through it without any damage <br />15 to the tailings facility itself. <br />16 UNIDENTIFIED PERSON: Excuse me. The <br />17 drainage swale is like a stilling basin; is that <br />18 what you mean? <br />19 MS. BALDRIGE: No. The contouring for <br />20 the facility creates a channel, a defined channel, <br />21 and then gently undulating topography to ~:reate a <br />22 swale. <br />23 UNIDENTIFIED PERSON: I picture that as <br />24 kind of a stilling basin, a wider area, or am I <br />25 misunderstanding here? <br />AGREN, BLANDO & BILLINGS <br />
