In accordance with and NMAC, New Mexico Environment Department (NMED) provides this public notice of a remote public hearing associated with the proposed, i.e., draft, groundwater discharge permit (Discharge Permit or DP-831) for the Waste Isolation Pilot Plant (WIPP or Facility) beginning at 12:00 p.m. on September 7, 2021, and continuing on as needed. The link to the virtual platform for the hearing, including how to join by telephone, can be found on the NMED Calendar at The draft Discharge Permit was prepared in response to a discharge permit application submitted by the U.S. Department of Energy (DOE or Applicant) for renewal and modification of the existing Discharge Permit. The hearing officer will provide opportunities for oral statements or non-technical testimony from members of the public at the hearing.

Name and address of the Applicant: U.S. Department of Energy, Waste Isolation Pilot Plant, Reinhard Knerr, Manager, Carlsbad Field Office, P.O. Box 3090, Carlsbad, NM 88221.

Location of the discharge: The Facility is located off Highway 128, approximately 26 miles southeast of Carlsbad, in Sections 20, 21, 28, and 29, Township 22S, Range 31E, in Eddy County. WIPP is a mined geologic repository for the disposal of transuranic (TRU) waste. Discharge locations at the Facility potentially affecting groundwater include an impoundment system collecting domestic wastewater (Facultative Lagoon System), three active/pending salt cells (Salt Cells 2, 3, and 5), four lined impoundments collecting stormwater in contact with salt cells (Salt Storage Ponds 1, 2, 3, and 5), three lined impoundments collecting stormwater not in contact with salt cells (Storm Water Ponds 1, 2, and 3), and five lined impoundments collecting non-hazardous, non-radioactive, industrial wastewater (Evaporation Pond H-19, Effluent Lagoons B and C, Brine Retention Ponds East and West, and Brine Salt Storage Pond 4).

Activities that produce the discharge: Discharges at this Facility include stormwater directed to synthetically lined evaporation impoundments from the Facility grounds and from active and inactive salt cells. Additionally, the Facility discharges industrial wastewater to synthetically lined evaporation impoundments from the following sources: brine, purge waters from sampling and developing Facility monitoring wells, condensate from the Exhaust Shaft fan ductwork on the surface, and water collected from the Waste Shaft Sump, Exhaust Shaft Interception Wells, and other observation boreholes in the underground. The Facility discharges domestic wastewater to a synthetically lined evaporation impoundment system. The Applicant proposes to discharge brine produced from the operations of the planned Salt Reduction System to two synthetically lined evaporation impoundments. The proposed Permit modification consists of the addition of one new salt storage cell and four new impoundments: Salt Cell 5, Salt Storage Pond 5, Brine Salt Storage Pond 4, Brine Retention Pond East, and Brine Retention Pond West. Salt Storage Pond 5 will receive both the leachate and stormwater in contact with salt located in Salt Cell 5.

Quality, quantity, and flow characteristics of the discharge: The draft Discharge Permit authorizes the discharge of up to 27,000 gallons per day (gpd) of domestic wastewater to the domestic wastewater system, up to 50,000 gpd of industrial wastewater to a synthetically lined evaporation impoundment, up to 2,210 gpd of brine to synthetically lined evaporation impoundments, stormwater off salt cells to synthetically lined evaporation impoundments, and stormwater (not in contact with salt cells) to synthetically lined evaporation impoundments. Potential contaminants from these types of discharge include nitrogen compounds, dissolved solids, and chloride. The discharge may contain water contaminants with concentrations above the standards of NMAC and may contain toxic pollutants as defined in 20.6.7(T) NMAC.

Depth to groundwater: Groundwater most likely to be affected is at a depth of approximately 35 to 160 feet and had a pre-discharge total dissolved solids concentration of 3,400 milligrams per liter.
