Dear Mr. Raines 0 Ms. Petrzelka:
We have reviewed your letter dated November 30, 2015, requesting renewal of the above
referenced substitute water supply plan ("SWSP") in accordance with S 37-90-137(11), C.R.S. This
SWSP is requested to cover depletions for five previously mined gravel pits (ponds) that are owned
and operated by the Tri-Districts and the City of Greeley ("Partners" or "Applicant") and located
within two permitted sites. The required fee of $514 (2 x $257) has been submitted (receipt no.
3672538A-B).
SWSP Operations
The two Treiber Lakes and three Lamb Lakes were constructed under DRMS permit no. M-
1977-439 (Home Office Pit). The Home Office Pit is operated by Martin Marietta Materials ("MMM")
and is included in their Upper Poudre Combined SWSP (WDID 0302517), most recently approved in a
letter dated June 26, 2015. The Treiber Lakes have officially been separated from the Home Office
Pit mining permit boundaries and are now covered under DRMS permit no. M-2011-049. The Lamb
Lakes remain within the boundaries of MMM's DRMS mining permit for the Home Office Pit.
Depletions from the Lamb Lakes will be replaced under this SWSP; however, final reclamation
liability remains with MMM as the Home Office Pit permit holder.
The Partners completed construction of a slurry wall around Treiber Lake A on August 7,
2013. The liner was approved on January 27, 2014 and re-approved (after intentional breaching) on
August 19, 2015 as meeting the design standard. Treiber Lake A is therefore classified as a lined
reservoir in accordance with the 1999 SEO Guidelines. All lagged evaporative depletions associated
with Treiber Lake A have been replaced under previous SWSPs. A slurry wall is scheduled for
construction around Treiber Lake B during the spring of 2016. The projected depletions associated
with the slurry wall construction are included in this SWSP, along with past and projected
evaporative depletions for Treiber Lake B and the Lamb Lakes. Replacement sources under this
SWSP include releases of reusable water from mountain reservoirs, direct replacement from
transmountain sources, reusable municipal return flows from East Larimer County Water District, and
