First Quarter 2011- Horse Gulch Fill Quarterly Inspection Report
Dear Mr. Mattern:
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 ])(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 first quarter monitoring period from January to March 2011, and the
inspections were conducted by Seth Puls, a certified engineer.
4.09. 1 (11) (b) 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 March 30, 2011, and the report was received by the Division on
April 7, 2011. No instability, structural weakness, or other hazardous conditions were noted during
this inspection.
4.09. 1 (11) (c) Any certified report addressing the underdrain system and protective filters shall include color
photographs taken during and after construction, but before underdrains are covered with excess
spoil. If the underdrain system is constructed in phases, each phase shall be certified separately.
...photographs shall be taken of the underdrain as the underdrain system is being formed. The color
photographs accompanying each certified report shall be taken in adequate size and number with
enough terrain or other physical features of the site shown to provide a relative scale to the
photographs and to specifically and clearly identify the site.
The report includes no photographs of the underdrain system and related construction activities.
This is acceptable because construction was complete in the first quarter of 2011, and no additional
construction activity is anticipated.
No problems or maintenance items were noted during the inspection of the Horse Gulch Excess Spoil Fill.
If you have any questions feel free to contact me. [phone], extension 8113.
Sincerely _
