Enclosed are calculations of the anticipated flow from each <br /> of the topsoil piles, and sizing of the catchment basins. The calculations have been <br /> done by Scott Jones, P.E. <br /> The request for minor revision and the accompanying calculations should be placed in <br /> the Mid-Continent permit application in Volume 2, Appendix 11-B-5, starting as page 170. <br /> Revised maps, indicating the catchment basins, are enclosed with this request, and <br /> should be inserted as 11-B- App. 5-4 and II-B-App. 5-10. <br /> Yours very truly, r o <br /> 1 <br /> Diane Delaney <br /> Mid-Continent Res. <br />
