Thank you for your letter dated June 28, 2005. As we have discussed, and as you discuss in your letter, due
to certain timing problems with the public notice for the Worthing Pit permit amendment application, the
public comment period for this application has been extended to August 22, 2005. As a result, the Division
of Minerals and Geology (DMG) is considering your letter as being timely filed. As to the issues raised in
your letter, the DMG has jurisdiction over the protection of ground water and your water well, and over
adverse impacts caused by dust generation. The other issues raised in your letter, truck traffic, noise, and
reduced property values, aze not issues that the DMG has authority to consider. Regulatory authority over
these subjects is vested with local government.
The DMG has investigated the potential for your water well to be impacted by proposed operations at the
Worthing Pit. Enclosed with this letter is a diagram constructed from information contained in the permit
files for your well maintained by the Office of the State Engineer. Careful examination of the diagram
shows that the source of water to your well is isolated from the alluvial aquifer, in which the Worthing Pit is
operated. This isolation consists of well casing that is cemented to the surrounding geologic formation, and
a barrier of more than 100 foot thickness of relatively impermeable claystone bedrock. The DMG's ground
water experts conclude that the Worthing Pit operation will have no impact on the quality and quantity of
water pumped from your well.
To further investigate the dust issue raised in your letter, the DMG has requested additional information
from the applicant. The following quotation is taken from an August 11, 2005 letter from the DMG to
i Greystone Environmental Consultants, who aze the permitting consultants for Albert Frei and Sons, Inc.:
DMG notes that Exhibit M to the AM-Ol application lists two permits from the Air
Pollution Control Division (APCD) as being in effect at the Worthing Pit. DMG views
obtaining and being in compliance with all required APCD permits to be an adequate
demonstration of sufficient dust control at operations such as the Worthing Pit. Please
state affirmatively that the Worthing Pit has, and is in compliance with all required APCD
permits, or describe what additional permitting or compliance obstacles remain, if any.
