Re: Permit No. M-2000-082 - East 8Street Operation
Dear Mr. Ebert: ,/
In response to corrective action ssseet forth in your report on the Division's inspection conducted March 31,
2010, Aggregate Industries (AI) submits the following:
With regard to mining within 200 feet of certain structures prior to obtaining Division approval, as noted
in the inspection report:
Prior to mining within 200 feet of the Ogilvy Ditch, AI's plant manager communicated with the
Ogilvy Irrigation & Land Company (Ogilvy) Board president, who agreed to allow mining closer
than 200 feet; however a structure agreement was not secured at that time. Following the
Division's inspection, I communicated with the now former Ogilvy Board president and he
affirmed the previous communication and permission. A structure agreement form stating AI's
commitment to repairing, replacing or compensating Ogilvy for any damage that might be caused
to the ditch has been provided to the former Board president for signature. While still a member
of the Board, he is no longer an officer and therefore passed along the structure agreement for
signature by the appropriate person. We are still attempting to secure the signed agreement and
would therefore request a thirty (30) day extension of time to October 30, 2010 to address this
matter.
As the inspection report indicates, Al has affected land within 200-feet of East 8"' Street
(Colorado Highway 263); however AI's operations in that area to date have been limited to
stockpiling of overburden material, which will not adversely affect the stability of this structure.
Extraction of material within 200-feet of this structure, which may have the potential to affect the
stability of this structure, has not occurred. In accordance with an agreement with property owner
Greeley Urban Renewal Authority (GURA), Al has maintained a minimum 200-foot mining set-
back from the property boundary until GURA decides whether or not to have a slurry cutoff
trench installed around the perimeter of the mine, and as East 8t' Street (Colorado Highway 263)
structure and associated right-of-way is located north of the mine, outside the property boundary,
it is 200 feet or more from the current extraction area.
We would additionally note that upon AI's initial notification and submittal of an agreement
regarding proposed mining within 200 feet of Colorado Highway 263 to the Colorado
Department of Transportation (CDOT), dated September 11, 2000, CDOT requested an
