We have reviewed your letter dated November 18, 2010, requesting approval of a
substitute water supply plan ("SWSP") on behalf of Loloff Construction, Inc. ("Loloff' or
"Applicant") to cover depletions caused by an existing gravel pit operation. This site was
previously covered under the combined SWSP for Aggregate Industries ("Al"); however a
separate SWSP was obtained by Loloff for the site in 2008. The required renewal fee of $257
(receipt no. 3648080) has been received.
SWSP Operations
The Loloff Pit (WDID 0303012) is a gravel pit operation located in the SE% of the NWY4 of
Section 4, Township 5 North, Range 65 West of the a P.M., in Weld County. This SWSP will
make replacements to the Cache La Poudre River for depletions resulting from mining operations
during the 2011 plan year, and for lagged depletions from past operations at the Loloff Pit.
Consumptive uses at the Loloff Pit site include evaporative losses from two ponds within the permit
boundaries, and operational uses. The operator (Ron Richardson) does not anticipate that the site
will be dewatered or mined below the water table during 2011; therefore the amount of exposed
ground water is expected to remain constant. The current permit to expose water in a pit, permit
no. 67479-F, limits the total surface area of the ground water pond(s) to 8.3 acres. According to
your letter, a new permit application will be submitted in the near future for the current area of
exposed ground water. The replacement sources proposed to be utilized in this SWSP are leases
with the Platte River Power Authority and the Graham Drainage Ditch Company.
In accordance with the letter dated April 30, 2010 (copy attached) from the
Colorado Division of Reclamation, Mining, and Safety ("DRMS"), all sand and gravel
mining operators must comply with the requirements of the Colorado Reclamation Act
and the Mineral Rules and Regulations for the protection of water resources. The April
30, 2010 letter from DRMS requires that you provide information to DRMS to demonstrate
you can replace long term injurious stream depletions that result from mining related
