Maxwell Mine File No. C-013-81 RESPONSE TO DRAFT FINDINGS DOCUMENT XVII B ackfilling and Grading - Rules 2 .05 .3(b) , 2 .05 .3(9) , 2 .05 .4(2) (a) , 2 .05 .4(2) (c ) 4 .09 , 4 .13 , and 4 . 14 CF&I does not intend to fill the portal depression area at the Maxwell Mine. This feature was established and in use prior to August 3 , 1977 . This area contains only slightly more than two acres of the total disturbance area, has slopes at or less than standards for terrace slopes, will not impound water, and does not depart from the approximate general nature of the topography in the immediate area. This feature will not pose a risk to the environment or public health and safety upon completion of the reclamation work at the Maxwell Mine. The second part of the stipulation of this section references backfilling and grading of other areas at the Maxwell. We contend no additional backfilling is required and grading will consist of rounding and blending in of contours . CF&I requests an on-site meeting with a representative of the division to look at the need for this requirement if the following and information does not answer the question adequately. CF&&I in response to a stipulation in Part 5 of the draft findings document, agreed to the removal of the sedimentation ponds at the end of the reclamation effort. The ponds and the appropriate volume of material to be moved are listed below. Pond No. Volume 002 -900 cy 003 17 ,800 cy 004 9,500 cy Total 28 ,200 cy The material, including topsoil for placement back into the sediment control pond areas, is adjacent to each pond in the embankments around them. The portal itself will be sealed and covered as per the submitted plan application (Pg. 2 .05-34-36 . The amount of material required to cover the portal seal will be approximately 600 cubic yards. This material, except for a minor amount of topsoil; will come from the final waste disposal area.
