RE: East Rigden Pit,Permit M-1979-097,Annual Fee Payment and Report
To Whom It May Concern,
Enclosed are the annual report, map and payment for the East Rigden Pit Permit M-1979-097.The East
Rigden Pit has been under permit for many years and currently still has batch plant operations on the
west-central portion of the site by Cottonwood Properties. A majority of the permit property was
purchased by the City of Fort Collins ("City")in 2014.As part of the purchase, the City agreed to take
over the mining permit. Much activity took place in 2014 and 2015 to construct Rigden Reservoir and
move material around to various portions of the permitted area for final reclamation.The majority of
construction and reclamation was completed in June 2015,prior to the submittal of last year's annual
report.
Since August 2015, additional work at the site has included additional seeding, some topsoil transfer from
the north end of the site to the central portion and activities related to erosion issues around the perimeter
of the new reservoir.These numbers are reflected in the answers to the attached annual report form and
shown on the attached map. Unfortunately, some areas of the seeding did not take well and will need to
be reseeded, which is planned to occur this fall.
An area near the northwest portion of the site has recently developed exposed groundwater, which is
shown on the attached map.We are currently considering options to address this situation and plan to
have a solution in the coming year. Once addressed,documentation will be provided on the solution.
The southwest portion of the site is still owned by Cottonwood Properties. About 27 acres of that portion
are still used for batch plant operations and the remaining area is slated for future development which will
involve distribution of a topsoil stockpile on the that portion of the site. The City hopes to fully reclaim its
portion of the site in the next year and potentially have the City's parcels released from the permit.
Please note that the permittee name has changed from Cliff Hoelscher(who recently retired)to myself
(Donnie Dustin), which was changed in the annual report form. Otherwise,please let me know if you
have questions or concerns.
Thank you,
Donnie Dustin,P.E.
