. ~~ ~ -4- 24. Atap G shows several areas mapped as Qun[ernnry unconsolidated deposits , (Terrace, Landslide, Colluvium, and Alluvia]. Deposits). The text in section 785 report that most of these deposits are terraces or colluvium and are therefore not alluvial valley floors. Provide a more detailed map showing [hc areas identified as alluvium, terrace, and colluvium in the drainages of Fish Creek, Foidel Creels and Middle Creek and identify rise field and other observations made to support the designations anti delineations. 25. On what basis were terrace deposits excluded from being Alluvial Valley Floors? Terrace deposits are normally considered elegib.le for deslgnatton as alluvial valley floors• 26. What criteria were used to distinguish between colluvial and alluvial deposits? Provide the data and assumptions upon which this determination was based. 27. The application has no[ demonstrated a lack of water For flood irrigation. The 2.0 acre-f t• criteria in the OSFI technical gutdence paper Is 2.0 acre-ft/acre of irrigable land not 2.0 acre-ft/acre of watershed as calculated by the applicant. The applicant should determine runoff during the various seasons and based on both direct irrigation during flows and storage estimate how many acres could be irrigated. 28. Page 780-217 states that additional information concerning design of ponds D,E,F,G, and 0 would be submitted on or about October 15, 1979. This material has not yet been submitted. It should be :submitted prior to final regulatory authority action. 29. Two different sets of assumptions were used to size sediment storage. For all ponds except pond A, three different values were used as the CP (VM) factor in the Universal Soil Loss Equation; one for "base land", one for early reclamation, and one for natural or fully reclaimed land. For pond A, only two values were used for the CP factor. The applicant should clarify iiow these values are obtained and used. [dhich set of calculation are snore conservative? For how many years is an area in each state of reclamation? 30. A statement on 816-48 indicates that some ponds may be 1ef.t at [he site following reclamation if required by State or Federal i.aw. Are any ponds presently planned to be left as permanent empoundmenLS? lJhich ponds could he left to satisfy State or Federal haw? What laws are hci.ng considered? 31. Runoff volumes for ponds were estimated under APICLII but in [he design pond culverts, ACIC II used to determine peak flow. ~.Jhy were two different assumptions used? Culverts should be sized for same runoff conditions as pond volume, i.e., the worst case situations. 32. In Eckman Park, temporary d the active pit. The constructio is unclear. Describe the proced ditches be constructed? What sp located in areas otherwise undis stripped of topsoil? Ltches are proposed [o divert runoff around ~ and operation and maintenance of the ditches gyres. How far in advance of the pit would the icing between ditches? 4Jould the ditches he Curbed or would they he constructed in areas
