The current <br /> permittee for the East 8th Street Pit (M-2000-082) is Superior Oilfield Services Co., LTD and the current <br /> operator is Laser Oilfield Service LLC ("Laser" or "Applicant"). This pit was previously included in the <br /> Aggregate Industries Combined SWSP (WDID 0202565) but has been covered under a separate SWSP <br /> since November 1, 2012. The required fee of $257.00 for the renewal of this substitute supply plan <br /> has been submitted (receipt no. 3683672). <br /> SWSP Operation <br /> The East 8th Street Pit (WDID 0303016) is located just east of the City of Greeley in the south <br /> half of Section 4, Township 5 North, Range 65 West of the 6th P.M., as shown on the attached Figure <br /> 1. The west cell of the pit has been fully mined out. Dewatering of the west cell ceased in July <br /> 2016 and was allowed to refill over the following three months (August through October 2016). <br /> Dewatering of the west cell restarted in November 2016, and continued through January 2017. <br /> During February and March of 2017, the water table was below the level of the pit so there was no <br /> pumping required for dewatering, and the pit did not refill with water. The west cell was <br /> dewatered again during April 2017. The west cell was filled during free river conditions in May and <br /> June, eliminating the need to account for any "intermittent fill" of the pit. Mining and dewatering <br /> operations switched to the east cell in August 2017 and are anticipated to continue at the east cell <br /> throughout the plan period. Depletions at the East 8th Street Pit during this plan period will consist <br /> of evaporation from exposed surface area, water removed in the mined product, water used for <br /> dust control purposes, and lagged depletions associated with the "intermittent fill" of the west cell <br /> that occurred in 2016. The City of Greeley is the owner of the land on which the East 8th Street Pit <br /> is located. Greeley will provide replacement water from their waste water treatment plant <br /> pursuant to the mining lease agreement between the Applicant and Greeley.
