State environment department adds terms for Los Alamos National Lab radioactive gas release

The New Mexico Environment Department says Los Alamos National Laboratory will need to meet additional conditions before the state will sign off on a release of radioactive gas, and lambasted the lab for allowing the problem to mount over decades.
The issue concerns four containers the lab packed in 2007, which contain radioactive gas tritium and some hazardous waste, and require pressure release by 2028 in order to be transported and disposed of. LANL has requested state officials sign off on a plan to release small amounts of gas over time to relieve the pressure, and said the releases will not harm the environment and human health.
Tritium, a radioactive isotope of hydrogen, can be naturally occurring or a byproduct from nuclear research, according to the U.S. Environmental Protection Agency. The EPA characterizes the gas as a lower threat, emitting radiation that often cannot penetrate the skin and leaves the body quickly when consumed as tritiated water.
In a June 9 letter to officials at the National Nuclear Security Administration and private contractor Triad National Security, which operate LANL, NMED Secretary James Kenney decreed the lab will need to hire an independent technical reviewer for the plan; hold public meetings and tribal consultations; and submit to an audit of hazardous waste disposal operations, before approval will be given.
'In closing, the historical gross mismanagement of these waste streams by DOE and NNSA have placed NMED in an untenable situation. Now, the risk of inaction poses a far greater threat than a technical solution, but no technical solution is free from risk,' Kenney wrote. 'Your disregard of state laws and rules governing these wastes for almost 20 years greatly exacerbated this situation and put New Mexicans, tribal communities, and our environment at risk.'
The state believes the laboratory can conduct the steps needed for approval within three months, New Mexico Environment Department Resource Protection Division Director Rick Shean said in an interview with Source NM Tuesday.
He said the time pressure from LANL on the plan could have been mitigated in the years since the waste containers were found in 2007.
'If they had dealt with that closer to that discovery time, we wouldn't be in this situation right now,' Shean said. 'So it was their lack of action when the problem was identified that has made this problem worse.'
The letter accompanied a complaint the New Mexico Environment Department filed over a failure of the federal government to fund the state's independent oversight of national lab activities. While the funding was eventually restored, the complaint said, the department incurred a little more than $8,400 in administrative costs and jeopardized water, air and soil monitoring programs — including for tritium releases.
The complaint requests that federal officials sign a commitment for future funds, issue reports to Congress on the funding and explicitly request the NNSA be named as a responsible party.
Federal officials have the chance to appeal the complaint in a hearing process before NMED.
Source NM emailed officials at Triad and the NNSA for comment late afternoon Tuesday, and will update the stories with further statements as needed.

State hearings on Southern New Mexico water utility fines postponed

(Courtesy of U.S. Environmental Protection Agency / David Esparza) Attorneys for state regulators and a Southern New Mexico water utility facing $250,000 in fines for arsenic level violations have agreed to push back hearings about the penalties. The hearings scheduled for Tuesday and Wednesday will now be held sometime in the fall, according to a joint motion filed last week by attorneys for Camino Real Regional Utility Authority and the New Mexico Environment Department. The utility supplies water for more than 19,000 people in Sunland Park, Santa Teresa and southern Doña Ana County, an area with high levels of naturally-occurring arsenic in the groundwater. State regulators first issued fines of more than $251,000 in March 2024, after findings that the utility's arsenic treatment plants were 'offline and bypassed' for more than a year, sending drinking water with 'high levels of arsenic' to residents. Drinking water with high levels of arsenic is associated with diseases such as diabetes, increased risk of cancers, and can contribute to heart and lung diseases and skin problems, according to the Environmental Protection Agency. Utility leadership has said in statements that they take the concerns seriously and have worked to lower arsenic levels, achieving compliance with federal standards. However, after a series of failed tests in May public officials and the state's top environment officials said they've lost confidence in the utility's leadership to address the chronic issues. In late May, the New Mexico Environment Department filed an amended complaint, claiming that the utility delayed reporting elevated arsenic levels for multiple days and failed to specifically report them to the state. 'The continuing cycle of non-compliance by Respondent which compromises the public's access to safe and reliable drinking water requires the application of a bad faith enhancement for each of the violations which are the subject of this enforcement action,' the amended complaint stated Regulators raised the total fine to $252,000. Attorneys for the utility objected to the addition of new allegations for the upcoming June hearing, and requested more time to address them. Both the utility and the environment department agreed to a calendar extending witness and discovery deadlines into August, with a final date for the new hearing to follow. The utility faces additional court dates beyond the administrative hearing later this year. A 3rd Judicial District Judge ordered parties to submit a further schedule in the civil lawsuit the state brought earlier this month against the utility, requesting the judge appoint a third party to take over the utility's operations. A hearing is scheduled for July in the civil lawsuit brought last year, which alleges the utility violated residents' civil rights. SUBSCRIBE: GET THE MORNING HEADLINES DELIVERED TO YOUR INBOX

UP Aerospace Successfully Launches Maiden Flight of the Spyder Hypersonic Rocket
WHITE SANDS MISSILE RANGE, N.M., June 16, 2025 /PRNewswire/ -- UP Aerospace has achieved a significant milestone with the successful launch of its high-performance Spyder rocket. The maiden flight took place at 7:00 AM MST at Launch Complex 36, marking a new era in hypersonic mission capabilities. The mission reached the threshold of hypersonic speeds similar to the UP Aerospace SpaceLoft rocket missions that have been operational for 20 years. The mission was funded by the Stockpile Responsiveness Program (SRP) at Los Alamos National Laboratory (LANL) and was executed with the support of the Navy White Sands Detachment. The LANL payload test vehicle was successfully deployed in flight. Spyder was specifically designed to support hypersonic missions reaching speeds of Mach 10. The launch vehicle is the result of an eight-year collaboration between UP Aerospace, Cesaroni Aerospace, NASA's Flight Opportunities Program, Marshall Space Flight Center, and Los Alamos National Laboratory. Since 2005, UP Aerospace and Cesaroni Aerospace have worked closely to develop cutting-edge solid rocket motors technologies including the Spyder booster and upper stage motors. Future developments of Spyder include the maximum performance booster motor and multi upper stage Spyder variants capable of achieving altitude's approaching 300 km to support a wide variety of hypersonic mission objectives. For over 16 years UP Aerospace has been providing launch services supporting a variety of customers including NASA, the European Space Agency (ESA), and LANL, and began developing Spyder technologies under the NASA 'Tipping Point' contract awarded in 2017. The Spyder rocket was developed to provide enhanced mass lifting and speed performance capabilities to support thermal protection system development, re-entry capsule stability and control evaluations, and high speed suborbital flight testing capabilities at a greatly reduced time and cost. Jerry Larson, President and CEO of UP Aerospace, commented on the achievement: 'The successful launch of Spyder-1 sets the stage for the next mission, which will integrate guidance and control systems into the Spyder-2 vehicle. We are excited for its upcoming launch, scheduled for early 2026.' View original content to download multimedia: SOURCE UP Aerospace, Inc.
