Re: Approval for the Request to Beneficially Use Lime Material from Past Sugar Beet Processing,
Leprino Foods, 1302 1s' Avenue, Greeley, Colorado
Dear Mr. Fiore:
The Hazardous Materials and Waste Management Division of the Colorado Department of Public Health
and Environment(the"Division")appreciates the opportunity to review your request to beneficially use
lime material from past sugar beet processing. The lime material for this project is currently located at
the proposed Leprino Foods site at 12th Street and Ash Avenue, in Greeley, Colorado. The Division also
appreciates your effort to construct a second test pad on March 31, 2010,using the proposed recycled
lime/soil mix.
Fiore constructed a test pad in the future building lot of the Fiore site at 8th and Balsam. Fiore placed a
mixture of 70% by volume of the spent lime waste and a 30% sandy soil from onsite. Ground
Engineering provided dry density and moisture testing services. The Division received a handwritten
copy of Ground's test results prior to leaving the site showing the test results. The results indicate that the
material met engineering specifications of 95%of the maximum dry density. The moisture content was at
or slightly below optimum allowing the material to achieve the recommended compaction.
The Division hereby grants approval to commence fill placement using methods practiced in the
construction of the test pad and those described in the "Final Design and Operation Plan for the
Placement of Lime and Soil Mixture on the Fiore Site Located at 8`h and Balsam Avenue"(the D&O plan)
dated April 30, 2009. The D&O plan requests the use of a 70/30 lime/soil mixture by volume as fill in the
non-building areas at the Leprino Site, and for the entire Fiore Site. The Division disapproves the
beneficial use of this material if the following placement conditions are not met:
• Material placement must meet local specifications and use requirements for fill placement. This
may include obtaining separate approval from the appropriate local entities for use of the lime
material as backfill material;
• Material must be placed at a minimum of 3 feet above groundwater;
• Material may not flow, creep, or pump after placement;
• Material may not be deleterious to vegetation;
• Materials may not impact surface or groundwater;
• Material must be covered with a minimum of one foot of native soil or topsoil;
• Material may not leach constituents into the surrounding soils;

• Constituent concentrations may not exceed the Colorado Soil Evaluation Values for unrestricted
use or groundwater impact whichever is the lower constituent concentration;
• Transportation of the waste material must not present a nuisance to surrounding properties
We look forward to working with you on this important beneficial use project. If you have any questions,
I can be reached at 303-692-3425 or by email at david.snapp@state.co.us.
