• # <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 pushing this <br />material into the nearest area of the pit. <br />TASK 4 (Demolition of structures): You have not included any demolition costs in your estimate. <br />however, the ramp and scale foundation have to be removed in order to reclaim this area to wildlife habitat. <br />Unit figures for asphalt, steel and concrete structural demolition have been taken tom the Means Cost <br />Estimating Catalog in estimating these costs. Dimensions were taken from the map or by onsite <br />measurements 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 [he broken asphalt material <br />from the pad, the broken concrete material from near the south permit area boundary and the ramp fill into <br />the pit were, therefore, included in [he Division's estimate. <br />TASK 6 (Rip operations and stockpile areas): Your estimate did not include any cost for <br />ripping/scarifying portions of the site. The Division again disagrees. Most of the area outside the 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 area be properly revegetated, they 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, Far purposes of the <br />Division's estimate, that only the pit Floor and slopes, ie. a total area estimated at 4.45 acres, will be <br />topsoiled to a minimum depth of 12 inches. If a swell factor is considered, only an estimated 5600 cu. yd. <br />of 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 />[his material on all the reclaimed slopes for the pit was esttmated to average 425 feet from this location. <br />(Since there is a question as to the volttme of topsoil onsite being adequate for reclamation, see Topsoil <br />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: I 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 [hen fertilized using a push spreader. A slope area <br />estimated at 2.4 acres has been used in the Division's estimate of the cost of revegetatmg the 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.I 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 VOLUME: Please be advised that this reclamation cost estimate assumes that 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 ]une 1, 1999 as specified under Compliance Problem 4 identified in the <br />repots of the Division's inspection on ?/3/99. If such a demonstration cannot be made by that date. [he <br />permit must be revised to import the necessary amounts of topsoil and/or the reclamation plan modiEed to <br />perhaps reduce the amount of topsoil required. If any topsoil must be imported to the site in order [o meet <br />
