Los Alamos National Laboratory 2018 Monitoring Season for storm water and atmospheric deposition samples from Bandelier National Monument under Permit # BAND-2018-SCI-0006 - 2018 Monitoring Season Summary

Los Alamos National Laboratory (LANL) completed the 2018 monitoring season for a multi-year monitoring project to characterize background/baseline conditions around and distal to the Pajarito Plateau, Northern New Mexico. The following media were included in the 2018 monitoring season: precipitation, storm water, and atmospheric deposition. Data generated in this study will be used to characterize and quantify the impacts to water quality from natural background sediments and atmospheric deposition of persistent organic pollutants such as polychlorinated biphenyls [PCBs]. Details specific to 2018 monitoring season are presented below.

TA-II Sub-Area Plan: Overview & Summary

Technical Area II is a brownfield site with a central, but “backyard” location that makes it a perfect area for site-support activities, particularly those that can be relocated from the TA-I “front-yard.” TA-II has a large amount of undeveloped land that should be held in reserve for future R&D mission work. Specifically, the Sub-Area Plan recommends: (1) Accommodating primarily site-support land uses, including site-support functions that can be relocated from TA-I; (2) Preserving land for future mission development opportunities which also protects sensitive environmental areas; (3) Locating future development along the Hardin and 9th Avenue corridors where existing infrastructure exists; and (4) Constructing critical infrastructure links (e.g., roads and utilities).

Draft Discharge Permit 1132 [Slides]

This presentation covers site hydrogeologic setting (including geologic setting and faults and fractures), groundwater monitoring for RLWTF, monitoring well locations, monitoring suite and frequency, quality of wells, and defense in depth – groundwater monitoring coupled with use of engineering controls and visual inspections. The objectives of groundwater monitoring are early detection of any future noncompliant releases, providing additional safety net to support extensive administrative and engineering controls, and monitoring to characterize extent of groundwater effected by noncompliant discharge.

Long-Term Monitoring & Stewardship at Los Alamos National Laboratory [Slides]

Development and implementation of the Institutional Control Evaluation Project will include: Evaluate institutional surface water controls and infrastructure installed by LANL. Implement pilot project in the Los Alamos Canyon Watershed Spring, 2020. Initial evaluations will include canyon bottom controls with plan to expand program as funding allows. This will be a building block for successful Long-Term Monitoring and Stewardship (LTM&S) Program.

Los Alamos National Laboratory Meteorology Monitoring Program: 2019 Data Completeness (Quality Report)

This report summarizes data completeness by tower and by instrument for 2019 and compares that data with the Los Alamos National Laboratory (LANL) and the ANSI/ANS-3.11-2015 standard. This report is designed to make data users aware of data completeness and any data quality issues. LANL meteorology monitoring goals include 95% completeness for all measurements. The ANS 2015 standard requires 90% completeness for all measurements. This report documents instrument/tower issues as they impact data completeness.

Wetland Delineation Report for Middle Mortandad Mesa Adjacent to Technical Area 55 at Los Alamos National Laboratory

This report provides the results of a wetland delineation conducted to support operational logistics for construction of a high-pressure water line that is planned to occur near a wetland at Los Alamos National Laboratory (LANL). The wetland reach is on the mesa edge in Technical Area (TA)-55 above the Mortandad Canyon watershed. This area has not been previously delineated; however, it drains to a canyon bottom where LANL updated a delineation in 2017 for the wetland adjacent to Technical Areas (TAs) 25, 48, and 55.

Los Alamos Climatology 2021 Update

The Los Alamos National Laboratory (LANL or the Laboratory) operates a Meteorological Monitoring (Met) Program to support LANL emergency response, engineering designs, environmental compliance, environmental assessments, safety evaluations, weather forecasting, environmental monitoring, research programs, and environmental restoration. Weather data has been collected in Los Alamos since 1910. A 30-year averaging period is termed by the National Weather Service (NWS) as a climatic normal, and these statistics are updated every 10 years to represent the current climatic normal conditions. Previous climate statistics are provided in Bowen (1990) for the 1961–1990 averaging period and Dewart et al. (2017) for the 1981–2010 averaging period. No climate statistics were developed for the 1971-2000 averaging period. This report provides climate statistics for the current 30-year 1991–2020 averaging period.

Planning is Key for Storm Water Regulatory Compliance [Slides]

Most construction projects at LANL are subject to a EPA regulated storm water discharge permit (NPDES Construction General Permit). Each identified non-compliance is a regulatory liability to both the subcontractor & Triad.

LANL Meteorological Program Self-Assessment 2021 Update

This self-assessment, documented in Table 1, has shown that there has been continued significant progress achieved in meeting the intent of the 21 recommendations from the 2015 DMCC Assist Visit. Every year after the Assist Visit, the LANL Met Program has improved, mainly by addressing the recommendations in the Assist Visit report. The Met Program management should continue to strive to apply its limited resources and seek to acquire additional human capital and physical resources to meet the dynamic needs of its growing sitewide customer base. This includes additional upgrading of the hardware and software elements of the Met Program and implementation of its operational procedures and QAPP to ensure it will consistently meet important present program requirements, as well as anticipated future requirements. These improvements have been summarized in the “present improvements and future initiatives” column in Table 1.
