Sieve Richardson -2- June 18, 1981 locations also appear acceptable. They occupy the head of each valley with little or no watershed above them. They will be protected from the full force~of winds, unlike the ridge-top site. In keeping, Exxon indicated that plans for these two additional piles and an amended plan for the ridge-top pile will be submitted in the near future. WEr also had an opportunity to examine sediment ponds no. 3, 4 and 5, located iri the Lower portion of the project site. Each of these sediment ponds appears to be adequately constructed and is now functional. Middle Fork of Parachute Creek Problem Area Jerry and Z stopped to examine that stretch of Pfiddle Fork Valley immediately at~ove Union Meadow. We were not pleased by what we saw! The streams channel has obviously suffered considerable additional damage in the past several months since we last saw it. While Union's revision number 3 proposed to place the majority of the road material within the bermed area, it appears as though perhaps half of the overall material was actually spoiled downslope into the channel of Parachute Creek. To make matters worse Exxon extended it:saccess road approximately 30 feet east into the creek. At one point the extended berm actually fills the original low-flow stream channel. Tcgether Exxon and Union have completely destroyed approximately 500 feet of the original channel and valley of the Middle Fork of Parachute Creek. In my opinion the valley will have to be artificially reconstructed to restore its hydraulic character. In addition, some allowance should be made to allow deer, elk and other wildlife access to the upper Pfiddle Fork Valley. (Division of Wildlife should be consulted) I do not see justification for the extension of the access road to the Colony project. I believe it should be removed and restored to its original configuration. .I suspect that the road embankment will also require r~.prap armourment, in order to prevent eventual erosion. Union Meadow Exxon's recently constructed alternative straight access road route across the western prong of Union Meadow is an aesthetic atrocity. The rechannelized stream has already eroded one small toe section of the embankment where it "~ ~' infringed upon the channel. In my opinion in order to accorradate wildlife and reduce the visual impact the berm should be regraded to perhaps 1 foot above 100-year flood stand or 3 feet above original grade, which ever is the lower, (the approaches could be regraded to accomodate the change in grade) or the embankment should be removed. Some allowance will have to be Trade for wildlife crossing the new embankment, which might necessitate an underpass and therefore a highergrade. The Division of Wildlife should be consulted. Logan Wash Jerry Zimpfer and I toured the Logan Wash Occidental Oil Shale site and dis- cussed the surface drainage topic at some length. Neither one of us could envision a good location in which to place sediment control facilities for the disturbed area. 1 do not believe Jerry feels they would accomplish enough to warrant their construction. The vast majority of the disturbed area within the Logan Wash site appears to be the access road, which is excempted from sediment control. We did notice, however, that the parking and storage areas
