RE: 83rd Joint Venture; ID #M-1992-069
Dear Mr. Hayes:
I am writing on behalf of the City of Greeley in reply to the Division of Reclamation, Mining &
Safety's ("DRMS") December 14, 2016 inspection report and the January 12, 2017 response to
that report from Aggregate Industries ("Al"). The City endorses the March 17, 2017 letter
written to the DRMS by Eric Reckentine on behalf of the Boyd Irrigation Company("BIC").
In addition to the latest letter from the BIC and the accompanying report from Wright Water
Engineers, Inc. ("WWE"), you also have complaint letters dated May 27, 2016 from both the
City and BIC, as well as WWE's initial report. I will not repeat the information you already
have,but rather will add those concerns specific to the City.
The significant erosion damage to the City's F Street agricultural property was, undeniably,
caused by AI's operations. Al admits that. The January 11, 2017 report from AI's consultant,
Tetra Tech states: "We agree that the increased flow velocities led to the erosion of the
reclamation slope, hence the breach of the pipeline and the erosion of the F-Street Agricultural
Field."
Al's operations produced an immense ravine cutting across the City's property. In the long term,
if this ravine continues to expand it could rechannel the Cache la Poudre River and flood City
neighborhoods. In the shorter term, the City has suffered damages in the amount of$470K,
which is the cost to restore the City's eroded property to its previous, undamaged condition.
It is our expectation that DRMS will require AI to restore the City's F Street property to the
condition that would have existed if not for AI's operations. And, that the DRMS will require Al
to perform the stabilization work requested by the BIC to prevent future erosion from occurring.
