On behalf of the U.S. Department of Energy Environmental Management Los Alamos Field Office, legacy cleanup contractor Newport News Nuclear BWXT-Los Alamos (N3B) will conduct a public meeting and 45-day public comment period for adopting new water quality criteria for copper for surface waters around Los Alamos National Laboratory (LANL). The water quality criteria is being developed in accordance with the U.S. Environmental Protection Agency’s nationally recommended copper water quality criteria for protection of aquatic life.
A draft report is available for comment at n3b-la.com/outreach. Written and oral comments will be given equal weight and N3B will consider all comments received or postmarked by November 9, 2023. Written comments should be sent to N3B Copper Water Quality Criteria Comments, 1200 Trinity Drive, Suite 150, Los Alamos NM 87544, or emailed to: N3BOutreach@em-la.doe.gov

What Is the Individual Permit for Storm Water?
The Permit - LANL SWIP Final NPDES Permit
- was issued by the U.S. Environmental Protection Agency,
Region 6, on June 29, 2022 to Newport News Nuclear BWXT-Los Alamos, LLC and the U.S. Department of Energy Office of Environmental Management.
The Individual Permit became effective on August 1, 2022.
The Permit contains nonnumeric technology-based effluent limitations, coupled with a comprehensive, coordinated inspection and monitoring program, to minimize pollutants in the Permittees’ storm water discharges associated with historical industrial activities from specified SWMUs and AOCs. The Permittees are required to implement site-specific control measures (including best management practices [BMPs]) to address the nonnumeric technology-based effluent limits, as necessary, to minimize pollutants in their storm water discharges.
The Permit establishes target action levels (TALs) that are equivalent to New Mexico State water-quality criteria. These TALs are used as benchmarks to determine the effectiveness of control measures implemented under the Permit. That is, confirmation monitoring sample results for an SMA are compared with applicable TALs during the Site Specific demonstration (SSD). The SSD places SMAs into one of three tiers. The Tiers are as follows; Tier 1, Site Deletion; Tier 2, Long-term Stewardship; and Tier 3, Corrective Action.
