<br />XIV. OPERATIONS DESCRIPTION (2.05.2, 2.05.1(1), 1.nS.J(Z) ~rnd X1.01)
<br />The mine operations general description and mine facilities sections of the permit
<br />application have been reviewed by the Division and OSM11. The applicant has provided
<br />sufficient information on the proposed operation to assess compliance with Colorado
<br />Permanent Regulatory Program in the areas of coal recovery, prevention of degradation
<br />of environmental quality, adequacy of reclamation and to assure that the rights of
<br />surface Zan down ers and other persons are protActed for the hJC ;t Rdi qe and 1do Ffat
<br />areas. The applicant is in compliance with parts :'.05.2, 2.05.3(]), 2.05.3(2), and
<br />9.01. See specific sections for further determination of compliance.

<br />The Moffat Area will continue to be mine d.uncil 1991 but economics for northern portion
<br />of the permit area have not been determined. Therefore, the life of mine timing is
<br />uncertain.
<br />The available geologic, environmental, and op@ration al data in the permit area indicate
<br />that the company is in compliance with Section 4.01.1(1) of the Colorado Permanent Reg-
<br />ulatory Program. Coal recovery wi1.1 he ma:rimized during this permit term.
<br />County Road Number 27 is within 100' of the i.ermit area. This nor ti on of the permit area
<br />was previously permitted in 7977 prior to the ne,v law Caking effect. Pherefore, the road
<br />is grandfathered from the 100' limitarion.

<br />Overburden handling in other amps is in compliance. .:'n o::erburden storage is pro-
<br />posed. Therefore, r.•ith the .inclusion of fire proposer] stipulation, tl:e applicant is
<br />in compliance with Farts 2.05(2)Ic), 4.09 and 4.1; o[ the C'olnrario Permanent Regula-
<br />tory Program.
<br />POSTMINING TOPCiGRA.°If l'
<br />Generally, the applicant's proposed post mining contours app mximate the pre mining land
<br />forms. Exceptions include the box-cut and final cut areas.
<br />The applicant stated that the proposed post-mining contours Here determined by a
<br />volumetric analysis of the proposed nit size, volume of material which will be
<br />spoiled into the pit based upon the above-described handling, and an estimated 20
<br />percent swell factor. Verificatior. of this analysis by the applicant was supplied
<br />for the box-cuts and final cuts. Quantitative verification was given for the swell
<br />factor, but as an overall sr.~e11 of land of 21.4e (Section J.4.2). This results in a
<br />swell factor of 15.So, as calculated according to 4.14 of the Regulations. To confirm
<br />the swell factor as analyzed and to more accurately estimate the post-Wining contours,
<br />the applicant will monitor the post-mining Land surface by surveying cross-sections
<br />as shown in Section 3.4.2.
