RE: Great Western Dairy Groundwater Setback, AgPro Job Number 1703-11
To Whom It May Concern:
During 2005 AgProfessionals installed groundwater monitoring holes at the proposed site
for Great Western Dairy. Several bores were conducted on the Northeastern property and
subsequent holes were bored on the western property where the dairy was eventually
constructed. Field tech reports from the installation and initial readings of these holes are
attached. One abnormality was noticed on hole #6. This observation hole was drilled
with a 2" auger and the initial depth reading was 10.8ft. Subsequent readings
approximately 11 days later showed the water elevation at 17.7ft. This discrepancy in
water level measurements did cause a small concern prior to construction. To verify
actual water level prior to construction staking I personally measured the water depth on
April 12, 2007 to verify the depth. Depth to groundwater was observed at 21.3ft on this
date. It was determined that the 10.8ft reading was a mis-reading due to the hole being
drilled and measured the same day.
Pre -construction groundwater readings from various seasons and an as -built survey of the
ponds indicate that there is greater than the 4 ft setback from the liner to seasonably high
groundwater. This setback meets the requirements of the old version of Regulation 5
CCR 1002-81.5(6) which was applicable when the ponds were constructed, and also
meets the new version of 5 CCR 1002-81.8(6) adopted June 30, 2008.
Sincerely,
Agricultural Engineer

Peggy,
This is the latest e-mail I have from Troy Swain. As far as I know nothing has changed. If
AGPRO or the applicant has addressed these conditions they need to let Troy Swain
know/provide copies to him so he can confirm.
Sincerely,
Chris

Chris, I can't remember if I called you about this. Regarding USR-1583 Great Western
Dairy meeting prior to recording the plat conditions, they haven't applied for a CAFO
Discharge Permit (Condition F.) and haven't provided us with any information demonstrating
that the ponds meet the setbacks to groundwater and wells (Condition E.).

Ron,
Attached are the liner certifications for the 2 holding ponds at the
Great Western Dairy, along with a letter from our engineer outlining the
status of the manure separator and the related certification. I
apologize for the delay in getting this sent to you. Following your
inquiry and a review of the client files, it was discovered that a
certified liner certification was never obtained following final
installation of the synthetic liners this last spring. The overall
1
system appears to be working: as designed.
Please contact me should you need any additional information. I will
send a hard copy to your office today as well.
Merry Christmas,
Don

Hi Don:
Regarding Great Western Dairy, it does not appear that its liner
certifications are in our file. Were they submitted? If not, please
submit them by Friday, December 19, 2008. We have an inquiry from Weld
County about the liners and also need to have the certs in our files.
As we understand the facility, a liner cert should exist for the
following, at minimum:
* Three (3) lagoons
* Two (2) solids settling basins
Thanks Don
Take care
