The creation of lined <br /> n.moff strucA.-.ures on the dow'icast slope reevaluated. The stabilitv <br /> and lor-Igevity of any chamnels constr��ted on this steep slope is in qutcistion. <br /> S]ope in this fashion would undoubtedly create otIxsr unforeseen <br /> impacts (.X-f slope stability. An alternate course has been proposed. <br /> Using a technique whjch has been pr-oven in Europe, the bid doctmoc,_m-t will <br /> incltxde the ccxist�.tction of N-YJge brushlayers consisting of hand du/g cont��r <br /> furrows on 12 foot centers. Each furrow will have shn./b cuttinqs or tublings <br /> buried 2/3's their length on one foot sp-acings. Native shrub tzutblings 1­1ave <br /> beff-i or'dered from a nursery. We will still need to obtain shrub ct.tttings <br /> on-site. Cuttings 3 feet in ler-iqth wcLtld consist of willows, currant., <br /> butffaloberr/ and other cm-idemic species adjacent to tY-�_- pr-oject <br /> cutting prcx-ess wcL.tld ir-j no way be detrimental to the shrub and in ess��ce <br /> would act as a proninq mechariism. In addition to the hedge brL/shlayer <br /> construction, seedling trees would be planted within constructed retaining <br /> structzLres spaced 80 feet apart. <br /> All of the otlner reclamation work cited in the project narrative wa'tld be <br /> ccx-,str�/cted inckxjingv minor rUmon struc-bures to divert water flcmis <br /> frOff.] t�W_- uprx-_r coa} flat a-id slope ar-eas, the r-elocation, rF-grading and <br /> reclamation of the existinq coal waste pile northeast of the eastern do��slope <br /> area adjacent to [*oal Creek, and the regrading of the upper ccal flat to <br /> proinote revegetaticm ���cess includir�g contz�ur furrowing and t�xe selective <br /> handling of /naterials suitable for revegetation. All disturbed would be <br /> seeded, and crimpsl. Constructiom is still scheduled to in <br /> Jylv, 1991.
