INSPECTOR'S INITIALS ~S
1. A general monitoring inspection was conducted of the North Delta Pit. The caretaker, Mr.
Ray Tool, was present at the time of inspection. The operation ie currently inactive.
However, the appearance of the site was very clean. The operator has done an exemplary job
of contemporaneous reclamation. Remaining reclamation reeponeibilitiee in~:lude respreading
a small volume of salvaged topsoil over the stockpile area and revegetation of the lake
shoreline and stockpile areas.
2. The North Delta Pit ie permitted for 66 acres of disturbance with a financial warranty
of $13,500. The financial warranty appears to be adequate to complete the remainder of the
reclamation plan. The poet-mining land use le recreation and wildlife habitat. Completion
of the mining plan will result in a 55 acre lake. The location of the facility ie
approximately 1/4 mile north of the North Fork of the Gunnison River and directly southwest
of the Delta golf course. Because of the proximity of the site to the Gunnison River,
dewatering is required during mining. The operator discharges pit water to the Gunnison
Aiver under the terms of an existing NPDES Permit issued by the Colorado Department of
Health.
3. The mine plan specifies 4 phases of disturbance. Currently, there ie disturbance in each
phase. A lake approximately 10-12 acres exists in the Phase IV area. The shoreline has
been carefully graded to a 3:1 elope and topsoiled as required. All of Phaeee II and III and
an small portion of Phase I contain stockpiles of processed aggregate ae well as topsoil over
a large flat area. There ie also a large stockpile of recycled asphalt ire the west end of
the Phase III area. The size of the pile is estimated to be 4500 cubic yards. This material
does not appear to be saleable and provisions for its removal should be invade prior to or
during final reclamation. Please comment on the statue of this material.
4. Canada geese and other waterfowl were actively using the lake in the Phase IV area.
There were also deer tracks noted in the stockpile area. The site appears to be well suited
for recreation and wildlife use.
5. Review of the permit file does not indicate that provisions for evaporative lose from the
lake have been made. Under the terms of Senate Bill 120 this site may require either a well
permit or an augmentation plan. The Division lists this concern as a problem and requests
that Corn Construction respond within 30 days to verify whether all requirements of the State
Engineers Office for evaporative loss have been complied with. If not, the [~ivieion requests
that Corn Construction submit the appropriate application(s) to the State Engineers Office
within 60 daya. if the concern for evaporative lose is not addressed by thce operator within
60 daya, then the Division will require an additional reclamation bond for dewatering and
backfilling the lake.
6. The North Delta Pit did not contain an entrance sign or permit area mazkers as required
by Rule 3.1.12. Therefore, we request that an entrance sign be posted and the permit area
identified within 60 daya in order to comply with this requirement.
