("Asphalt Specialties" or "Applicant") in <br /> accordance with section 37-90-137(11), C.R.S. The Applicant shall be responsible for compliance with <br /> this SWSP, but the State Engineer's Office ("SEO") may also pursue the landowner, for eventual <br /> compliance. The original plan was approved on August 3, 2016, and its renewal was most recently <br /> approved in a letter dated July 10, 2020. The required fee of $257 for the SWSP has been paid (receipt <br /> no. 10012628). <br /> SWSP Operations <br /> The Chavers Mining Resources site is located in the E '/z of the SW '/a, Section 18, Township 1 North, Range <br /> 66 West of the 61h P.M. (Figure 1). The site is actively being dewatered to facilitate dry mining. The <br /> dewatering water is discharged into a sedimentation pond to settle out fines and from there into another <br /> dewatering trench which discharges to the South Platte River as shown on Figure 2. During the previous <br /> SWSP approval period, mining operations occurred in the western portion of Cell 3. Mining operations <br /> during this approval period are to be located in the northern portion of Cell 4. There is also a concrete <br /> production plan on Cell 1 at the site which utilizes groundwater from the onsite alluvial well, permit no. <br /> 80120-F. Cell 1 has been mined and backfilled. <br /> The property was historically used for irrigation. The source of the irrigation water was an alluvial well, <br /> permit no. 12258-F (WDID 0206393) previously augmented under the Ground Water Association of the <br /> South Platte River ("GASP"). The well is no longer in use for irrigation. Under the original SWSP, the <br /> Applicant requested a temporary change of use of water from this well to supply a wash plant with <br /> settling ponds, concrete production, and dust control water. The Applicant obtained permit no. 80120-F <br /> for the alluvial well (previously permit no. 12258-F) for industrial use associated with the mining <br /> operation at the Chavers Mining Resources site. During the period of this SWSP, this well will supply water <br /> for concrete production only. <br /> The depletions that result from the mining operation over the period of this SWSP include evaporation <br /> from exposed ground water, dust suppression, dewatering, concrete production, and water lost with the <br /> w �i tl :�1I�orl ra�,3 5,h a�r <br /> �e riu �� <br /> rriStl t, ao ��� 21, Lp.,� u�ewie <br /> r, C IC�nn�d�r i 0r F ���3 �' )6.3581' vrvry o rol, i.ado go w�' at��� <br /> K4.°vii,i G sae 1rY.
