Keenesburg Ash Disposal Facility
The Hazardous Materials and Waste Management Division (Division) of the Colorado Department of
Public Health and Environment reviewed the above referenced Request for Semi-Annual Groundwater
Monitoring Frequency (Doty & Associates, LLC letter dated October 27, 2012). Additionally, the

In consultation with the Weld County Department of Public Health and Environment, the Division
approves the Keenesburg Ash Disposal Facility request to conduct semi-annual groundwater monitoring
at the site with the following conditions:
1) The Division reserves the right to rescind our approval based on changing site conditions.
2) Semi-annual groundwater monitoring shall commence in the second quarter of 2013.
3) A map that depicts the potentiometric surface of the groundwater table as well as other pertinent
site features and information (as presented on the attached figure) associated with each fourth
quarter groundwater sampling event shall be submitted to the Division and Weld County within
ninety (90) calendar days of the sampling event.
In closing, the Division is authorized to bill for its review of technical submittals pursuant to Section 1.7
of the Regulations Pertaining to Solid Waste Sites and Facilities, 6 CCR 1007-2. An invoice for the
Division's review of the above referenced documentation will be sent under separate cover.
