RE: Roadside Portals (Permit No. C- 1981 -041)
Technical Revision No. 63 (TR -63) Adequacy Review
The Division of Reclamation Mining, and Safety (Division) has reviewed the above referenced
technical revision application submitted to incorporate a discussion of the flow variations in the
French drain system at the South Portal area and to provide a new design for the drainage ditch
H -H that crosses sediment Pond 9 (yet to be reclaimed in 2013). With former Technical
Revision No. 61 SCC was given approval for removal of Pond 9 and demonstrated that
associated disturbed areas will contribute fewer suspended solids to stream flow or runoff
outside the permit area than untreated drainage from the natural surrounding premising area.
This was accomplished by a soils loss comparison between disturbed locations and
corresponding non - disturbed reference areas using the Universal Soil Loss Equation. SCC has
also adequately demonstrated that the quality of untreated drainage from these disturbed areas
meets the State and Federal water quality standard requirements applicable after the
sedimentation pond is removed, for receiving streams. We have reviewed the TR -63 application
in its entirety and have no concerns with the new design for drainage ditch H -H that will cross
the reclaimed location of Pond 9 once it is removed.
However, during our review we noted that there were discrepancies in the permit application
package regarding the owners of record of surface and subsurface within and contiguous to the
permit area. This information was last updated in July 2011 with Technical Revision No. 62.
The Division has the following comments.
1. Please update Table 3 -1 in Volume 1, Tab 3 of the PAP to include Russell D. Conner as
a surface owner.
