rlr. Fbwrd B. Tingley February 17. 1981 Page ltto eh~ statf rscosmtads the maintenance of a 25 foot grassed butfsr of separation between the canal and the proposed mining activities. Tha Grass buffers should help to reduce the amount of eadin:ent transported to off- aite areas ae a result of on-site surface disturbance. S. Please spscily how reclamation will occur on the nettling pond. Ths staff rseo~ids that the berm be leveled over the final pond prior to asedbed preparation. If the hem is to remain es ie, the harm slopoa should ba reduced to 3: 1. and all compacted ereae should be ripped prior to ssadbad preparation. 6. On all arose whets surface activitise will occur (e.g., excavation. stock- piling, on-site traffic and parking locations). 12 to 18 inches of Potts loam soil end 8 to 12 inches of Vann Sandy Loam should be removed (prior to surface disturbance), sepreaated, sad stockpiled separately from one ano- ther. The approximate location and ertsat of the stockpiles should ba identified on the Riming Plan Hap. All cosQtactad arau should be ripped, prior to topsoil replacement and seedbsd preparation, to a depth of 12 inches under dry soil or overburden conditions. The Fluvsnt topaoll should also be removed and stockpiled to an extent which would alloy the minimum replacement of 6 inches of the Copeoil to affected Ianda remaining above eater, where snch Fluvente originally occurred. Excess Pluventa could be utilised in the construction of the proposed settling pond berm. Ateae which will remain under eater will not requite Copsoil replacement. 7. Pleass bs sore specific as to the nature of the on-site generated dsbria other than treas. Vesta forget or woody vegetation should ba placed along the river and southerly pond banks under the following guidelines if optiamm cover ie to be established: a. Place or stack material in piles not Co exceed 5 feet in height by 10 feet in length by 10 to 15 feat in width. b. Separate piles by 20 to 30 foot sections of grassed open apace. c. Do not pwh material in with a doser or in a moaner which would intermix soil or overburden with the vegetation. d. The piles should be eompriaed predominantly of slash from elu bucked boles of the tress. Soma boles and root balls can bs included. The remnindsr of the boles and root balls can be placed in the final pond for aquatic habitat and twat. Too much vsQatatiw material in the pond could result is premature autrophieation of the pond. thsrsfors sateen material may need to be hauled from the site or utilized as firewood. Large rocks should be atoekpiled and utilized for rip-rap or included in the final pond bottom. 8. Plaaee Illustrate the location sad extent of any significant doer crossings which intersect tlu site. fibers neseasary, maasursa should ba developed which would provide for the aafaty sad protsetion of dear on rheas crossings during czitical periods. 9. Plaaee give a more detailed description of the percent cover of the mayor species of vebstation presently occurring on the site. Whsra poaaibla, measures should ba taken to protest nature cottoavoods.
