installation methods included in the application and consist of (from bottom-to-top) two (2) feet of compacted clay or a GCL, overlain with a 60-mil HDPE secondary liner, overlain with a 60-mil HDPE primary liner, overlain with two (2) feet of a protective soil layer not composed of waste.


2. Each pit must be equipped with a Leachate Collection System (LCS), including 200-mil HDPE drainage layer that covers the entire pit area on top of the primary liner.

3. Each pit must be equipped with a LDS, including a 200-mil HDPE drainage layer that extends over the entire pit between the primary and secondary liners.

4. The liner system, the LCS and the LDS must be consistent with the “Leachate Collection And Leak Detection Details” (Drawing No. 39) schematic, received on November 19, 2018, which is attached as Permit Appendix F.

5. The liners, the LCS and the LDS must be installed in accordance with the application, the material manufacturer’s specifications and sound engineering practices.

6. The floor of each disposal pit must have at least a one percent (1%) slope to allow fluids to drain to the sump located at the low end of the pit.

H. A liner anchor trench must be used to key the synthetic liners for each pit to their respective berms. The liners must be welded together to create a continuous liner system when the next disposal pit is constructed. The tie-ins and anchor trenches must be consistent with the “Landfill Liner And Final Cover Details” (Drawing No. 38) schematic, received on November 19, 2018, which is attached as Permit Appendix G.

I. A permanent liner boundary marker must be installed and maintained on all four sides of the pit that clearly identifies the subsurface liner system weld locations at the land surface.

J. The area surrounding the pits must be graded such that all surfaces slope away from the pits, to prevent surface flow storm water from entering the pits.

K. Unless otherwise required by the conditions of this permit, construction, use, maintenance, and closure of the disposal pits must be in accordance with the information represented on the permit application and the attachments thereto.

VIII. Disposal Pit (P012729, P012730, P012731, P012732, P012733, P012734, P012735, P012736, P012737, P012738, P012739 and P012740) Operation

A. Only one Disposal Pit Phase may be considered active and accept oil and gas waste at any time.

B. The permittee must not construct or use any Disposal Pit in a manner that could exceed the financial security required by Permit Condition I.C.

C. The Permittee must contact the Midland District Office to proceed with construction of each disposal pit in the sequence and may not begin accepting waste until: 1. The Permittee has received approval from the Midland District Office to begin

accepting waste in next Disposal Pit in the sequence. 2. Waste is no longer being accepted in the previous Disposal Pit Phase and the

interim cover is almost completed. D. Before the Permittee may begin excavation of the next Disposal Pit Phase in the

sequence, the previous Disposal Pit Phase must be filled with waste to almost final grade height, and the exposed side abutting the next pit in the construction sequence must be properly graded and prepared to receive waste. Intermediate cover must be


installed over the final outside slopes of each disposal cell as the next cell is opened. Interim cover must consist of 1-foot of compacted cover soil that meets a hydraulic conductivity of 1 x 10-7 centimeters per second or less and has been compacted to 95% Standard Proctor (ASTM D698) or 90-92% Modified Proctor (ASTM D1557) density. The temporary cap must be graded to prevent ponding on top of the cover and inhibit infiltration of liquids into the wastes below.

E. After the intermediate cover has been constructed it must be inspected every quarter for erosion, slope stability, and thickness of the cover. The results of each inspection must be submitted as part of the Quarterly Report required in Permit Condition I.U. The physical record must be maintained by the permittee for the life of the pit.

F. The intermediate cover must be inspected after each storm event and re-compacted as needed to meet the requirements specified in Permit Condition VIII.D.

G. At least two (2) feet of horizontal freeboard must be maintained between the edge of the waste in the active disposal pit and the top of the pit dikes.

H. Prior to the Disposal Pit accepting waste above grade, the waste collected below grade must be stabilized, compacted and maintained to prevent collapse of the structure and must not have side slopes steeper than a one-to-three (vertical-to-horizontal) ratio.

I. Once the Disposal Pit begins to accept waste above grade, the pit freeboard (buffer) must be constructed and maintained to contain all contact stormwater that may be generated during a 25-year, 24-hour storm event for Reeves County.

J. Once the waste height exceeds 50 feet, the side slopes may not exceed a one-to-four (vertical-to-horizontal) ratio.

K. No freestanding fluids may accumulate in any Disposal Pit. Any fluids must be removed within 72 hours of discovery and disposed of in an authorized manner.

L. The leak detection system must be monitored as required by Permit Condition IV.N. If the LDS indicates a possible liner system failure, the liner system must be inspected for deterioration and leaks within five days of the detection of the failure. The Midland District Office must be notified by phone or email within 24 hours of detection of the failure. No additional waste may be added to the affected Disposal Pit(s) in the event of a failure. After inspection, the identified failed component must be replaced or repaired and re-inspected by RRC personnel before resuming use of the pit(s). A liner system failure is defined as any of the following: 1. A volume withdrawn from the LDS that is greater than:

Total 70.99

2. Any failure in the leak detection and return system or any component thereof. 3. Any detected damage to or leakage from the secondary liner.

M. Leachate collected in the leachate collection sump must be removed through the leachate removal pipe and disposed of in an authorized manner.

N. The RRC reserves the right to require necessary design modifications prior to capping and closure to ensure that the waste is stabilized above grade. Prior to receiving waste at 50-foot intervals above grade, a stabilization geotextile may be required to provide increased tensile strength to stabilize the compacted waste.

O. The permittee must notify the Midland District Office and Technical permitting in Austin each time the waste height exceeds the 50-foot interval above grade.

P. Unless otherwise required by conditions of this permit, construction, use, and maintenance of each pit must be in accordance with the information represented in the permit application and attachments thereto.

B. After each Disposal Pit Phase has reached the permitted capacity: 1. Waste material in the Disposal Pits must be compacted and stabilized, so that the

structure will not fail, slump or erode. The RRC reserves the right to require necessary design modifications to increase tensile strength prior to capping and closure to ensure that the waste is stabilized above grade.

2. Waste material in the Disposal Pit must be graded, stabilized, compacted and contoured so that rainwater will not collect on top of the pit.

3. The final cap must consist of (from bottom-to-top) a 1-foot temporary cap, overlain by a 40-mil HDPE liner, overlain by a 200-mil drainage layer, overlain by 18 inches of soil cover seeded with appropriate vegetation for the region.
