1.0 Introduction

The period covered by this report is the second calendar quarter of 2018 from April 1 to June 30, 2018.

Three Class I disposal wells were operational during the reporting period: LC DW No. 1 (“DDW1”), LC DW No. 3 (“DDW3”), and LC DW No. 4 (“DDW4”). Well locations (labeled) are shown below in relation to the Permit to Mine boundary (green line):

FIGURE 1: Well Locations

All three wells were operated intermittently during the quarter. Operational data was monitored and recorded electronically and also recorded manually by operator each shift.

A revised UIC Permit 16-145 was issued on June 28, 2018 and was received by LCI just after the end of the quarter. The new stipulations of the Permit were implemented during the next quarter.

As per UIC Permit 13-409 requirements, the following elements from Section K(6) of have been included in this report:

3.0 Analytical Results

A quarterly grab sample in duplicate of the injectate was collected from the Plant waste water line upstream of the branch points to each individual well. Sample parameters pH, conductivity, and temperature were measured with a field meter at the sampling site or in the onsite lab and other applicable parameters were analyzed by Energy Laboratories in Casper, WY. Results of the sample analyses are summarized in Table 3 below and the associated lab report is included as Appendix 2.

5.0 Alarms, Shut-Downs, and Corrective Actions

Nominal shutdowns both automatic and manual occurred due to pressure limit shutoff or due to maintenance activity such as changing inline filters or repairs. Intermittent operation of the injection systems is typical.

All three injection wells were off line in June for several days due to site wide operational shut down for repair of a Plant automation system component.

6.0 Summary of Maintenance, Well Tests, or Workovers

Maintenance completed during the quarter included:

• Routine filter changes • Replacement of annulus nitrogen tank for each well as needed • DDW-1: 5/31/2018 Pump motor packing replacement • DDW-3: 6/7/2018 Replacement of a valve and broken fitting. Resulted in leak and short-term

increase in flow rate.

Testing of the pressure switches to verify operation of automatic shutdown occurred in June. Digital shutoff is tested by reducing the shutoff pressure setting to prevent test pressure from exceeding permit limit and verifying the system shuts off at that pressure. Results of the testing are summarized on Table 5:

CASE NARRATIVE

Report ID: S1806306001

Sample DDW Injectate was received on June 18, 2018.

All samples were received and analyzed within the EPA recommended holding times, except those noted below in this case narrative. Samples were analyzed using the methods outlined in the following references:

"Standard Methods For The Examination of Water and Wastewater", approved method versionsTest Methods for Evaluating Solid Waste, Physical/Chemical Methods, SW-846, 3rd Edition40 CFR Parts 136 and 14140 CFR Part 50, Appendices B, J, L, and OMethods indicated in the Methods Update Rule published in the Federal Register Friday, May 18, 2012ASTM approved and recognized standards

All Quality Control parameters met the acceptance criteria defined by EPA and Inter-Mountain Laboratories except as indicated in this case narrative.
