June 22, 2011 <br />Impoundments 4,05.6, 4.05.9; Stream Buffer Zones 4.05.18: <br />The site was dry and there was no evidence of recent precipitation. <br />C- 1992 - 080 /Carbon Junction Mine TAK <br />Pond 1 (large pond, outfall 001). The two sediment control ponds were approved for removal in Technical <br />Revision 15 (approved in January 2008) and MR -6 (vegetation cover data, approved August 11, 2008). Pond 1 <br />(the large pond) was regraded in early 2009 and backfilled with all of the material from stockpile #8. Regrading <br />resulted in a flat surface that blends well with the adjoining flat, tilled farmland just outside the permit area to the <br />south. Ditches that fed Pond 1 have also been regraded. Runoff from this large flat area would make its way to <br />natural drainages on either side of Ewing Mesa, in the same way that runoff from the farmland would naturally <br />drain. <br />Pond 2 (small pond, outfall 002 ). Pond 2 also was regraded in early 2009, with the earthen embankment <br />removed, leaving a flat - bottomed drainage that reports a short- distance to the lower part of Carbon Junction <br />Canyon. Runoff from the west half of the PRSA will continue to flow through this drainage to Carbon Junction <br />Channel, via a culvert underneath the permanent asphalt - surfaced haul road. <br />Carbon Junction channel. The reconstructed section of the Carbon Junction channel was in good shape. <br />Sediment control. The vegetative cover established on the disturbed areas of the Carbon Junction Mine appears <br />to be effectively controlling erosion. No significant gullies or sediment fans were found on the site. Erosion on <br />the disturbed areas of the site appears to be occurring at a rate similar to adjoining undisturbed lands. The base of <br />the North Pit reclaimed slope is contoured to act as a grass filter for trapping sediment in runoff coming off of the <br />slope where the south half of the North Pit was approved as a small area exemption in TR -14. This grass filter <br />terrace was in good condition. <br />GENERAL MINE PLAN COMPLANCE: <br />There was no evidence of on- the - ground development on the reclaimed lands of the approved postmining <br />land uses of industrial or commercial, or residential. <br />ROADS — Rule 4.03 ❑ ❑ Construction 4.03.1(3)/4.03.2(3) ❑ ❑ Drainage 4.03.1(4)/4.03.2(4) ❑ ❑ Surfacing and <br />Maintenance4.03.1(5) and (6)/4.03.2(5) and (6)1 ❑Reclamation 4.03.1(7)/4.03.2(7): <br />The asphalt - surfaced main haul road was in good condition. The main haul road and the North Pit haul <br />road have previously been approved for permanent retention, as documented in Appendix 5 -1 of the permit <br />application. The width of the North Pit haul road has been reduced to 30 feet as specified on page 5 -26 of the <br />approved reclamation plan. The road surface of the North Pit haul road was in good condition during the <br />inspection. <br />RECLAMATION SUCCESS - Rule 4.15, Rule 3: <br />The reclaimed lands appear ready to support the approved postmining land uses of industrial or <br />commercial, or residential. <br />REVEGETATION — Rule 4.15 ❑ ❑ Vegetative Cover; Timing: <br />Number of Partial Inspection this Fiscal Year: 9 <br />Number of Complete Inspections this Fiscal Year: 4 <br />Page 3 of 8 <br />
