The application provided a discussion regarding Phase I bond release. However, there is no
discussion or detail that provides information to allow the Division to evaluate drainage control
on the bond release block in accordance with Rule 3.03.1(3)(a).
Please provide:
A. A discussion and drawing (or figure) of the sump /stock tank. There is no discussion or
depiction of the sump /stock pond located at the south end of the bond release block on
the map included with the SL5 application, "Exhibit A ".
B. Please demonstrate that this sump /stock tank has the appropriate permits from DWR or
has been designed in accordance with DWR requirements (i.e. it does not exceed size
limitations and has the necessary spillway and /or freeboard.) and meets requirements as
applicable to Rule 4.05.9(13).
C. The map provided by SCC did not include any topographic contours or show the location
of the sump /stock tank. Please provide a map or drawing (or figure) that provides
adequate topographic detail to allow the Division to determine runoff direction and
identify constructed features, i.e. sump, drainage channel, culverts, etc, Rule 3.03.1(3)(a)
and Rule 2.010.30).
The bond release block has been approved for a post- mining land use of commercial /industrial.
However, SCC needs to provide a discussion how the site has been stabilized and not eroding. If
the site or portions thereof have been vegetated, please provide a discussion of what is growing in
accordance with Rules 4.15.10 (2) and (3) apply to the bond release block being requested. A
statistical analysis is not necessary. Routt County Road and Bridge Department required the
