Dear Mr. Clark:
We have received your August 2, 2021 letter requesting the renewal of a substitute water supply
plan ("SWSP") pursuant to §37-90-137(11), C.R.S., for a sand, gravel, and granite mine known as
the Parkdale Project, and operated by Martin Marietta Materials ("Applicant"). The most recent
SWSP was approved February 24, 2021 for the period October 1, 2020 through September 30, 2021.
The mine is permitted with the Division of Reclamation, Mining, and Safety under file no. M-97-054.
The $257 renewal fee has been received and given receipt no. 10014292.
SWSP OPERATION
The Parkdale Project is located approximately 12 miles west of Canon City on the north bank of the
Arkansas River, as shown on the attached Figure 1. The DRMS permit for this mining operation
allows for production of sand, gravel, and granite. For the term of this SWSP, depletions are
reported to occur from evaporation from the groundwater exposed as a result of previous sand and
gravel mining operations, dust control, material washing, and water retained in product hauled off
site. The granite mined in this project is crushed and used for asphalt, concrete, railroad ballast,
and other construction-related products.
According to the SWSP request, granite is primarily being mined at this time; however, sand and
gravel operations have not ceased and reclamation of the sand and gravel mine is not complete.
During the term of this SWSP, mining of granite at this site is expected to occur above the
groundwater table. Dewatering will not be necessary for granite mining operations; however,
dewatering at the site will continue in order to reduce the area of exposed water. Mining at the site
is estimated to continue for approximately 15 years.
