RE: Technical Revision Request for Fort Lupton Sand & Gravel, M- 1999 -120
Reclamation revision of Hill - Oakley phase
Dear Eric,
We respectfully request a Technical Revision to the Fort Lupton Sand and Gravel Mine, permitted under
DRMS Permit # M- 1999 -120. We have included a check for $216.00 to cover the filing fee.

Mining and Safety
For this Technical Revision, we are revising the reclamation plan slightly for the Hill - Oakley phase of the
mine. This phase was known as the Hill -Eber- Oakley phase when we amended the permit in 2005
(DRMS approval date - 2/11/2005). The mining operations and subsequent reclamation boundaries have
changed due to the needs of oil and gas producers on the Fort Lupton mine site.
- The Eber property has not been mined and will not be included in any water storage reservoirs. The
office and scale are currently located on the Eber property, so the Eber property must remain in the
permit limits. Any disturbed vegetated areas will be reclaimed with the approved seed mix. We have
attached an updated Exhibit C -3: Mining Plan Map to show this mining revision.
A positive change from negotiations with the oil and gas producers is that the TOP Operating oil well
(and related pipelines) that were located in the Hill -Eber- Oakley phase has been capped and will be
completely removed. With the removal of the oil well from the Hill property, we no longer need to
keep an oil and gas operations peninsula in the reclaimed reservoir, so we have changed Exhibit F:
Reclamation Map to show this reclamation revision.
- The mineable acreage of the Hill -Eber- Oakley phase was approximately 44 acres. With the deletion
of the Eber property from mining and the removal of the oil well in the Hill property, the mineable
acreage of the revised Hill - Oakley phase is approximately 39 acres.
- Finally, in keeping with the reclamation modification approved in TR04, L.G. Everist requests that the
reclamation for the Hill - Oakley pit be considered complete in a less than fully vegetated state. L.G.
Everist will do the initial seeding on the Hill - Oakley reservoir to ensure erosion control. The City of
Aurora would like to take over control of the Hill - Oakley reservoir as soon'as possible, and they are
willing to accept the phase in a less than fully vegetated state.
As you know, L.G. Everist and the City of Aurora have a Purchase and Sale Agreement in which Aurora
has agreed to acquire the water storage reservoirs and properties that make up the Fort Lupton Sand and
Gravel Mine. Aurora wants to take over ownership of reclaimed properties as soon as they are released
from the DRMS permit. Aurora is willing to accept each reclaimed water storage reservoir of the Fort
Lupton Sand and Gravel Mine in a less than fully vegetated state.
