RE: Aggregate Iudustries Reclamation Permit M-2000-087 - Millikeu Resource
Dear Mr. Kammerzell:
Thank you for discussing your concerns about Aggregate Industries' proposed gravel operation
with me. Based on our phone conversations, it is my understanding you have the following
concerns.
Visual Appearance
Aggregate Industries has agreed to plant a landscape buffer between your home and the mining
operation before mining begins. I have attached a mining plan that illustrates the proposed berm
for your review.
Impact on Irrigation Well and Domestic Wells
I spoke with our geologists about the impact of the slurry wall on your wells. They believe that
the slurry wall will not have a dramatic impact on your irrigation well because it is within the
South Platte alluvium and the groundwater is flowing from your well southeast, towards the
Platte. They also believe that the slurry wall should not have an appreciable impact on the
domestic wells' available pumping rates.
To ensure that the slurry wall does not negatively impact the operation of your wells, Aggregate
Industries will install pizometers near the property line to monitor [he groundwater. We would also
like your permission [o drill a monitoring well near your irrigation well so that we can measure the
drawdown of the water table during pumping. With this knowledge we should be able to anticipate
the likelihood of the well being prone to production problems during mining, and can anticipate the
need for mitigation. Aggregate Industries will commit to fix any well production problems that arise
during mining.
Weed Control
I have attached the weed control plan that Aggregate Industries submitted to the Division of
Minerals and Geology.
Fencing
Aggregate Industries does not anticipate that the site will be fenced.
