<br />TASK 3 (Push overburden pile into deep pit): Your estimate indicates that there is no overburden <br />to place back in the pit. The Division disagrees. There is a sizable berm of such material along portions of <br />the western permit area boundary. As a result, the Division has included in its cost estimate pusfting this <br />material into the nearest area of the pit. <br />TASK 4 (Demolition of stntctures): You have not included any demolition costs in your estimate. <br />however, the ramp and scale foundation must be removed in order to reclaim this area to wildlife habitat. <br />Unit fi;ures for asphalt, steel and concrete structural demolition have been taken from the Means Cost <br />Catalog in estimating these costs. Dimensions were taken Front the map or by onsite measurements <br />gathered during inspections. <br />TASK 5 (Push asphalt, concrete and ramp fill into pit): Only the concrete debris resulting from the <br />demolition of the scale foundation can be buried in place. The cost of pushing the broken asphalt material <br />from the pad, the broken concrete material from near [he south permit area boundary and the ramp fill into <br />the pit were, therefore, included in the Division's estimate. <br />TASK 6 (Rip operations and stockpile areas): Your estimate did no[ include any cost for <br />ripping/scarifying portions of [he site. The Division again disagrees. Most of the area outside [he pit and its <br />slopes has been compacted and/or is gravel covered as a result of the traffic, equipment, stockpiles, etc. <br />associated with the operation. In order that these areas be properly revegetated, [hey must somehow be <br />uncovered and loosened prior to any seeding. As a result, ripping these areas is included in the Division's <br />estimate. <br />TASK 7 (Distribute and smooth topsoil): You included a cost of topsoiling with a dozer in your <br />estimate which is considerably larger than the Division's. It has been assumed, for purposes of the <br />Division's current estimate, that only the pi[ floor and slopes, ie. a total area estimated at 4.45 acres, will be <br />topsoiled to a minimum depth of 12 inches. [f a swell factor is considered, an estimated X600 cu. yd. of <br />material would be necessary to accomplish this. Since the only topsoil stockpile identified as such in the <br />permit area is located in the extreme northwest part of the permit area, the push distance necessary to place <br />this material on all the reclaimed surfaces of the pit was estimated to average 425 feet from this location. <br />LThere is a question as to the volume of topsoil onsite beine adequate for reclamation. This question must <br />be resolved by June 1, 1999. See Topsoil Volume discussion near the end of this letter.) <br />TASK 8 (Revegetate slopes): You have included costs of grass seed, drilling of the seed, fertilizer, <br />fertilizer application, and disking of the seedbed in your cost estimate. You have not, however, <br />distinguished between the seeding and seedbed treatment necessary to deal with the pit floor, operations <br />and stockpile areas, and pit slopes. Revegetation of the pit slopes, since they are 2:1 slopes, cannot be <br />safely conducted by means of wheeled vehicles. Consequently, as the reclamation plan largely prescribes, <br />these slopes must be broadcast seeded, hand raked and then fertilized using a push spreader. An area <br />estimated at 2.4 acres has been used N the Division's estimate of the cost of revegetating [he reclaimed <br />slopes of the pit. <br />TASK 9 (Revegetate pit floor and operations areas): These areas can be reseeded using a grass <br />drill and other mechanized seedbed preparation and fertilization methods. A total of 7.1 acres, ie. 9.5 minus <br />2.4, has been used in the Division's estimate of the cost of completing the revegetation of the site. <br />TASK 10 (Mob/Demob): You have included such costs in your estimate which are in close <br />agreement with the Division's. <br />TOPSOIL VOLU1v1E: Please be advised that this reclamation cost estimate assumes [hat there is a volume <br />of topsoil salvaged and stockpiled on site that will be adequate to complete the reclamation of'the <br />disturbance that now exists according to the approved reclamation plan. This, however, must be <br />demonstrated to the Division by June I, 1999 as specified under Compliance Problem 4 identified in the <br />report of [he Division's inspection on 2/3/99. If such a demonstration cannot be made by that date, the <br />permit must be revised to import the necessary amounts of topsoil and/or the ceclantation plan modified to <br />perhaps reduce [he amount of topsoil required. If any topsoil must be imported to [he site in order to meet <br />
