<br /> Dear Mr. Heintz:
<br /> We have received your letter dated January 31, 2020, requesting renewal of the above referenced
<br /> substitute water supply plan ("SWSP") in accordance with Section 37-90-137(11), C.R.S., to replace
<br /> depletions caused by an existing gravel mining operation owned by Martin Marietta Materials
<br /> ("Applicant"). The required fee of $257 for the renewal of this SWSP has been submitted (receipt
<br /> no. 3696755). The original SWSP was approved on May 18, 2000 and it was most recently approved
<br /> in a letter dated October 2, 2019 for the period April 1, 2019 through March 31, 2020.
<br /> SWSP OPERATION
<br /> The Rich Pit is located in portions of the SE 1/4 of the SW 1/4 and the SW 1/4 of the SE 1/4 of Section 34,
<br /> Township 20 South, Range 63 West of the 6t" P.M. Martin Marietta Materials ("MMM" or "Applicant")
<br /> acquired the site from Lafarge West Inc. ("Lafarge") at the end of 2011. The Rich Pit has been
<br /> inactive since 2001. Mining operations on the site are expected to resume in April 2020. Ponds
<br /> created from previous mining activities under this plan cause stream depletions due to evaporation.
<br /> This renewal covers pond evaporation from the Active Pit (16.7 exposed acres) and the Wash Pond
<br /> Site (12 exposed acres), mining and washing of material, dust suppression, and pumping of a
<br /> sanitary/miscellaneous well. Permit No. 45995-F (WDID 1406466) was issued for the Active Pit for
<br /> exposure of ground water, dust suppression, product retention, and concrete batching. A well,
<br /> Permit No. 66042-F (WDID 1405128), is used for sanitary and miscellaneous purposes connected with
<br /> the Rich Pit.
