LANL PUBLIC NOTICE:

The U.S. Department of Energy (DOE) and Los Alamos National Security, LLC (LANS) submitted an alternative compliance request for Site 50-006(d) in M-SMA-7.9 to EPA on April 21, 2014. The alternative compliance request provides a detailed demonstration of why the permittees are unable to certify completion of corrective action under Parts I.E.2(a) through I.E.2(d) individually or collectively and outlines proposed corrective actions.   

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. If one or more confirmation monitoring result exceeds a TAL, the Permittees must take corrective action. The Permit requires that the Permittees either certify to EPA completion of corrective action at each Site by a specific deadline or seek to place individual Sites into alternative compliance, whereby completion of corrective action will be accomplished on a case-by-case basis pursuant to an individually tailored compliance schedule determined by EPA.

The public notices published in the Los Alamos Monitor and the Santa Fe New Mexican newspapers on April 29, 2014, are available on the Individual Permit for Storm Water website (http://www.lanl.gov/community-environment/environmental-stewardship/protection/compliance/individual-permit-stormwater/index.php) in the “What’s New” box.

The “What’s New” box also contains (1) a link to the alternative compliance request submitted to EPA on April 21, 2014, and supporting documentation and (2) a comment submittal form (for convenience comments may be submitted electronically). Hard copies of the alternative compliance request and all supporting documentation may be requested by sending an email to envoutreach@lanl.gov. Written comments will be received by the Permittees through June 15, 2014.

For questions or problems with the website, contact Los Alamos National Laboratory: Patricia Jones, P. O. Box 1663 MS K788, Los Alamos, NM 87545 or call/email 505.665.7748 / envoutreach@lanl.gov
