RE: Centennial Project, Status of Notice of Intent, Non-Confidential Portions, File No. P-2008-043
Dear Mr. Blubaugh:
The Colorado Division of Reclamation, Mining, and Safety (DRMS) has reviewed your submittals dated August 1 and
August 11, 2008 providing required additional information for the above referenced Notice of Intent to Conduct Prospecting
(NOI). DRMS has determined that the NOI remains incomplete. Please address the following items at your earliest
convenience bearing in mind that if you have not addressed these items within sixty days of the date of this letter the DRMS
may terminate this NOI (rule 5.1.3 of the Mineral Rules and Regulations of the Mined Land Reclamation Board).
The NOI proposes to seal the upper portions of the holes using bentonite chips. In accordance with rule 5.4.2(5), the DRMS
will instead require that the upper ten feet of each hole be filled with Portland cement grout. Since the lands to be drilled at
least have the potential to be cropped, DRMS will require that any casing be cut off and removed and that the top of the
cement plugs be completed three feet below ground surface, with the upper three feet backfilled with native soil and
mounded.
Thank you for the submittal and public disclosure of certain standard operating procedures for monitoring wells. In addition
to those provided, the DRMS has determined that standard operating procedures for data validation, collection of ground
water field parameters, and record keeping, including field notes are necessary prior to approval of the NOI. Also, a listing
of the types of samples to be collected from the monitoring wells and the parameters to be analyzed must be provided. These
requirements are in accordance with the provisions of House Bill 2008-1161 signed into law in May 2008.
Portions of the attachments to Powertech's August 1, 2008 submittal are illegible due to portions of the text being cut off at
the edges. Please provide fully legible replacement documents.
If you believe that any of the information you provide in response to this letter is confidential under Senate Bill 2008-228,
please place that information on sheets separate from the public information and clearly mark those sheets as confidential.
If you have any questions, please contact me at 303-866-4063.
Sincerely,
len KCSorenson
Reclamation Specialist
