Poudre Pits SWSP January 29, 2019
Plan IDs 3218 £t 4585 Page 6 of 8
For any gravel pit whose reclamation includes unlined ponds, a plan of augmentation
approved by the water court must be obtained to cover the long term evaporative depletions. Until
an augmentation plan is obtained the operator may post a sufficient bond to backfill or line the site
thereby eliminating any long term augmentation requirements, or permanently dedicate shares that
will be used in an augmentation plan to the pit. For any gravel pit whose reclamation includes lining
or backfilling of the pit, bonds must be posted that can be used to complete the reclamation plan
should the operator walk away from the site. The North La Poudre and La Poudre pits have been
bonded through DRMS and are in compliance with the April 2010 DRMS letter (approach #1 and #3). A
summary of each pit's status regarding their long term augmentation and bonding held through DRMS
is shown on the following table:

Conditions of Approval
hereby approve the proposed substitute water supply plan in accordance with §
37-90-137(11), C.R.S., subject to the following conditions:
1. This plan shall be valid for the period of January 1, 2019 through December 31, 2019 unless

with the statutory fee of $257 for each DRMS site, and with all necessary leases and other
supporting documentation, no later than November 1, 2019. If a renewal request is received

for operational losses from the mining of aggregate, production of concrete, and dust control.
The water use projected in this SWSP remains within the permit's limits.
3. Well permit no. 78235-F was obtained for the North La Poudre Pit in accordance with S
37-90-137(2) and (11), C.R.S. This permit allows for evaporation, dewatering, and

values listed in Table A of this approval. Should the total surface area exposed exceed those
amounts, the Applicant is required to immediately file an amendment with this office.
