The Electronic Public Reading Room (EPRR) contains Los Alamos National Laboratory (LANL) documents required for compliance with environmental regulations and permits. Other documents that deal with environmental issues are included in EPRR.
A handout describing the Electronic Public Reading Room at Los Alamos National Laboratory is provided.
In June 2020, Los Alamos National Laboratory (LANL) submitted letter ESHQSS: 20-025 to Region 6 of the Unites States Environmental Protection Agency (EPA). This letter transmitted the 2019 LANL Radionuclide Air Emissions Report to the EPA. This report summarizes LANL operations, air emissions of radionuclides, and subsequent off-site dose consequence from these emissions for calendar year 2019. This report is issued to meet requirements of 40 CFR 61 Subpart H, National Emission Standards for Emissions of Radionuclides other than Radon from Department of Energy Facilities. This regulation, called the Radionuclide NESHAP, establishes a limit of 10 millirem per year to the maximally exposed member of the public and requires an annual report to be submitted to the appropriate EPA Region by June 30th of each year. LANL’s off-site dose from airborne emissions of radionuclides in 2019 was 0.43 millirem. The normal practice is to issue this report directly to EPA Region 6 in June of each year, and then after the report is accepted by the EPA, re-issue the report for inclusion in the LANL Electronic Public Reading Room (EPRR). This second part is usually done in July of each year, but this step was overlooked in July 2020 due to other commitments. We regret this error. This omission was noted in late 2020; we are submitting the 2019 LANL Radionuclide Air Emissions Report to the EPRR now in December 2020. Aside from the addition of this cover sheet explaining the delay, the report is unchanged from the version submitted to EPA Region 6 in June.
