The Colorado Division of Reclamation, Mining, and Safety (CDRMS) has reviewed and found the above referenced
report to be in compliance with the following CDRMS regulations:
4.09.1(11)(a) Inspected at least quarterly by a reregistered engineer or other qualified professional specialist in
construction of earth and rockfill embankments under the direction of a qualified engineer
throughout the construction.
The certified report covers the third quarter monitoring period from July to September 2011, and the
inspections were conducted by yourself, a certified engineer.
Provide to the Division a certified report within 2 weeks after each inspection that the fill has been
constructed as specified in the design approved by the Division, The report shall include a
description of any appearances of instability, structural weakness, and other hazardous conditions.
The inspection was conducted on September 29, 2011, and the report was received by the Division
on October 11, 2011. According to the report, no instability, structural weakness, or other hazardous
conditions were noted during this inspection.
1. According to your report, wet topsoil was observed at the time of the inspection. The location of this wet
spot was reported to be above the 7470' bench elevation, ten to fifteen feet from the south collection ditch.
A small spring was discovered at this location. To mitigate this issue, a trench was dug with a track hoe to
the south collection ditch and backfilled with screened rock. The report indicates this item will be an
inspection point in the future. The Division concurs that this issue will need to be monitored to ensure the
mitigation methods used continue to function.
