Mitigation Action Plan for LANL Operations (September 2020)

A mitigation action plan was prepared for the Site-Wide Environmental Impact Statement for Continued Operation of Los Alamos National Laboratory, Los Alamos, New Mexico (2008 SWEIS [DOE/EIS-0380]) in December 2008. The 2008 SWEIS mitigation action plan (2008 SWEIS MAP) has been revised as needed to address significant changes, to incorporate new mitigations identified in other NEPA documents, to provide recommendations for ongoing mitigations, and to close completed mitigations. Incorporating mitigations identified in other NEPA documents, such as environmental assessments and supplement analyses, into one mitigation action plan provides a single and concise document for tracking all mitigations and reduces the redundancy of multiple annual reports. The 2008 SWEIS MAP has previously been revised three times: in 2010, 2014, and 2016.

The 2020 MAP revision (revision 4) reports that all but two of the mitigations identified in the 2008 SWEIS have been completed and addresses remaining mitigation commitments identified in other NEPA documents for the continued operation of Los Alamos National Laboratory (LANL). This 2020 MAP revision incorporates the new mitigations identified in the 2019 Supplemental Environmental Assessment for the Wildfire Hazard Reduction and Forest Health Improvement Program at Los Alamos National Laboratory, Los Alamos, New Mexico (DOE/EA-1329-S1) and the Final Environmental Assessment for the Proposed Construction and Operation of a Second Fiber Optic Line to Los Alamos National Laboratory (DOE/EA-2122). Since the majority of remaining mitigations are from other NEPA documents issued for LANL, the 2008 SWEIS MAP is being renamed the Mitigation Action Plan for Los Alamos National Laboratory Operations. This revision also formally closes out mitigations that were completed or integrated into established programs at LANL.
