RE: Centennial Project, Fourth Review of Notice of Intent Modification MD-03, File No. P-2008-043
Dear Mr. Blubaugh:
The Colorado Division of Reclamation, Mining, and Safety (DRMS) has reviewed Powertech's submittal
dated March 9, 2010 responding to DRMS third review of proposed modification MD-03 to Notice of Intent
to Conduct Prospecting P-2008-043, and has determined that there are issues remaining to be addressed.
Please respond to 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 consideration of
the proposed modification (Rule 5.1.3 of the Mineral Rules and Regulations of the Mined Land Reclamation
Board).
1. Powertech has requested the flexibility to use tanks regardless of previously stored contents. DRMS
approves this request. However, DRMS will continue to require that Powertech provide a commitment for
provision to DRMS of Rain for Rent's detailed history of the previous contents of tanks, at least back one
tank use event, and a commitment that the tanks will not be used to store produced ground water until after
the detailed history has been accepted by DRMS in writing. DRMS will not use this detailed history for any
reason other than to inform.and frame the evaluation of rinsate test results; tank history will not be used to
disqualify tanks that pass the rinsate testing and.meet all other requirements of MD-03.
2. Powertech has committed to pump test commencement after April 15 and to monitoring the long range
temperature forecast and postponing the pump test if "abnormally sub-freezing air temperatures are to be
expected." These commitments, along with the commitment to install valves and other plumbing to clear the
pipes if freezing potential were to develop, are sufficient for DRMS to eliminate the requirement to bond for
freeze protection equipment and equipment operation. In order to apply enforceable parameters to the
forecast monitoring commitment, please state affirmatively that Powertech will not commence the pump test
until such time that the National Weather Service forecast for the pump test location is free of any sub-25
degree Fahrenheit predictions.
DRMS estimates the cost to reclaim the pump test site at $63,670.00. The details of the cost estimate are
enclosed with this letter. This estimate differs from the DRMS cost estimate for MD-03 previously prepared
as follows:
a. Costs for freeze protection have been removed.
