Summary

San Francisco Board of Supervisors Rules Committee Meeting (Dec. 15, 2025)

The Rules Committee, chaired by Supervisor Shimon Walton with Vice Chair Supervisor Stephen Sherrill and Supervisor Rafael Mandelman participating (one item with Mandelman absent), heard and acted on appointments, accepted a biannual surveillance report for Juvenile Probation Department web filtering software, and held a major oversight hearing on the U.S. Navy’s delayed disclosure (nearly 11 months) of an airborne plutonium detection at Hunters Point Shipyard Parcel C. The Clerk noted items acted upon were expected to appear on the Board of Supervisors agenda of January 6, 2026 unless otherwise stated.

Public Comments & Testimony

  • No public comment was offered on the Housing Authority appointments, the Assessment Appeals Board appointment, or the Juvenile Probation surveillance report.
  • Hunters Point plutonium disclosure hearing:
    • Dr. Ahimsa Porter-Sumchai (founder, Radiological Subcommittee of the Hunter’s Point Shipyard Restoration Advisory Board) argued the Navy’s actions represented concealment/delay and violated the precautionary principle; asserted the exceedance source was near a “radiation staging yard” (referencing a Navy Inspector General verification in March 2024) and urged the City to seek a federal injunction to prohibit radiation staging yards adjacent to sensitive receptors.
    • Unidentified District 10 resident stated distrust of the Navy, characterized the situation as a “cover-up,” and called for honesty and integrity in disclosures.
    • Joyce Armstrong (Vice Chair, Hunters Point Shipyard Citizens Advisory Committee) said the committee was disappointed, perceived a pattern, and called for an independent investigation; emphasized the community wants disclosure “no matter how low” the level.
    • Nikki Vismar (artist, Hunters Point Shipyard; Shipyard Trust for the Arts) stated delays were unacceptable and undermined trust; while noting Navy communication to artists had improved over the last year, requested stronger visible dust/containment measures (e.g., windscreens, clearly defined screening yards) as a step toward rebuilding trust.

Discussion Items

  • Item 1 — Housing Authority Board of Commissioners: Appointments (3 seats; terms TBD in item heading)

    • Sharon Lai described growing up in public housing and a career spanning city planning, housing development, and community development; stated interest in serving during “uncertain budgetary times.”
    • Cynthia Alvarez (President/CEO, Christian Church Homes) described experience in affordable housing development/operations across six states and emphasized centering residents; shared personal immigrant background and governance/finance/compliance experience.
    • Supervisors Walton and Mandelman expressed support for both candidates’ qualifications and willingness to serve during challenging funding conditions.
  • Item 2 — Assessment Appeals Board No. 2: Appointment (term ending Sept. 6, 2027)

    • Jose Edmilson Sobral described finance and real estate/mortgage experience since 1999, including appraisal review and comparable-sales analysis during 2006–2011; stated these analytical skills would support board service.
  • Item 3 — Juvenile Probation Department: Biannual Surveillance Report (Administrative Code §19B.6) for a web filtering tool

    • Elisa Baeza and Cindy Aguilar (Juvenile Probation Department) presented highlights on a web filtering tool used for youth safety and programming at the Juvenile Justice Center, intended to filter harmful/distracting content (e.g., social media, games, explicit material) and prevent firewall bypassing.
    • Reported operational effects and statistics:
      • Staff review time dropped by 75% due to automated summaries and real-time monitoring.
      • April–May: 11,700 sites visited; 466 sites blocked.
      • September–October: 23,800 sites visited; 334 sites blocked.
      • They stated web usage doubled while blocked content decreased by 28%, presented as evidence of responsible use and effective filtering without overblocking.
      • They stated there were no incidents of prohibited communication such as contacting victims online while the tool was in use.
    • Supervisor Walton asked how to interpret the 28% decrease (department said it was a baseline-building year) and how “youth stay focused” is gauged (department cited real-time monitoring and staff ability to redirect).
  • Item 4 — Hearing: U.S. Navy delayed disclosure of airborne plutonium detection at Hunters Point Shipyard (Parcel C)

    • Chair Walton stated the Navy identified contamination in November 2024 but did not report it to San Francisco until October 2025, calling this unacceptable and part of a longer pattern of transparency problems; said the Committee sought full disclosure, accountability, and understanding of protections during the period the public was not informed.

    San Francisco Department of Public Health (SFDPH)

    • Dr. Susan Phillip (Health Officer for San Francisco; Director, Population Health Division, SFDPH) stated SFDPH is not a regulator under CERCLA/Superfund cleanup, but monitors and advocates for public health protection, transparency, and accountability.
    • SFDPH timeline (as presented):
      • Early Oct. 2025: SFDPH learned from the Navy that a Nov. 2024 sample showed plutonium above the action level.
      • Oct. 30: SFDPH sent a letter to the Navy requesting more information; community stakeholders copied.
      • Oct. 31: SFDPH convened a meeting with Navy senior leadership and EPA; SFDPH emailed a community statement that there was no immediate public health risk based on information shared.
      • Nov. 7: Navy letter indicated more info forthcoming.
      • Nov. 12: Navy sent lab reports and calculations to SFDPH.
      • Dec. 10: SFDPH told community stakeholders it reviewed information with regulators and reaffirmed no additional action was needed at that time.
    • Dr. Phillip stated the exceedance was above an action level but well below immediate danger levels, while noting her concern about delayed notification to regulators.
    • Dr. Phillip said her understanding was that notification timelines under the Federal Facilities Agreement were around two weeks, and agreed that was not consistent with an ~11-month delay.

    U.S. Navy

    • Anthony Megliola (Director, BRAC Program Management Office West) acknowledged the delay and took responsibility for the impact on trust; stated the detected concentration was “extremely low” and did not pose health risk.
    • Navy key claims and statistics:
      • Navy said it learned in March 2025 that a Nov. 2024 air filter sample showed plutonium-239 above its action level.
      • Navy described the action level as a dust-control screening threshold, not a health limit.
      • Navy stated it was the only plutonium exceedance among more than 200 samples collected since July 2023.
      • Navy compared the maximum potential dose from the detection as one-tenth of a San Francisco–New York flight dose or one hundredth of a medical X-ray (as stated by the Navy).
    • Danielle Janda (Navy team) provided details:
      • Said the action level was set at 20% of the health-based limit; described the maximum dose represented as 0.4 millirem per year.
      • Noted reanalysis of the same sample came back non-detect.
      • Said an independent third-party laboratory audit (through the DoD accreditation process) concluded in September 2025 the lab was operating properly; Navy cited this audit timeline as a reason for delayed reporting.
      • Reported operational context: work that week was limited (asphalt removal/grinding), real-time dust monitoring showed no exceedances, and simultaneous upwind sampling was non-detect.
    • Dr. Catherine Higley (Oregon State University, nuclear science and engineering; identified as a distinguished professor) stated the dose was so low it would be considered negligible by advisory bodies.
    • Chair Walton questioned whether the Federal Facilities Agreement required notification within two weeks even for a non-health-risk detection; Navy asserted the two-week requirement was for a health concern, not necessarily for an “action level” exceedance.

    U.S. Environmental Protection Agency (EPA)

    • Mike Montgomery (Director, EPA Region 9 Superfund & Emergency Management Division) said the exceedance did not pose a health risk, and offered a quantified risk statement: the potential increase in risk was “extremely small,” described as six excess cancer risks per 100 million people.
    • Montgomery stated EPA was informed on Oct. 23, 2025, and that under the Parcel C Work Plan the Navy should have notified EPA within two weeks of receiving the data in March 2025.
    • Montgomery stated EPA would, within 45 days, complete its review and provide a summary of its assessment, and would attend the January Citizens Advisory Committee meeting.
    • On accountability, Montgomery said the federal facilities agreement can allow stipulated penalties in certain instances, but he could not discuss consequences in this case due to ongoing enforcement discussions.

Terms to be determined. Thank you so much, Mr. Clerk, and I believe that our candidates are here. I will call them up in order that they appear on the agenda and you just have a couple minutes to tell us about Why you want to serve and be a part of this body? And so first we have Sharon Lai Good morning chair Walton supervisor Cheryl. I'm Sharon Lai It is an honor to be before you today to be considered for the housing authority appointment especially during these uncertain budgetary times. I actually grew up in public housing myself and having gone through housing instability up until my teens, so serving within the housing space has always been a motivator for me. I have had the privilege of living and serving the city for close to two decades now from working as a city planner for the San Francisco Planning Department, working on approving housing, zoning plans, to delivering and building housing across all types within the nonprofit and private markets. I have also worked on economic recovery efforts for San Francisco post-pandemic and currently work for a local community development corporation in the Bay Area where we primarily serve low-income families working to deliver and operate housing, providing services and community building efforts for three Bay Area counties. I'm currently the chief strategy officer there, which means that I work on resourcing alignment as well as ensuring that we are making the right decisions around where and how we do work. I happen to also have the privilege of overseeing two important departments there, including the community and resident services department, which is part of the work that the Housing Authority does, as well as community planning and placemaking. Is that my time? Well, I am very pleased to be able to continue to serve the city and look forward to contributing to the important work of the Housing Authority. Thank you. Thank you so much. And next we have Cynthia Alvarez. Hi, good morning. My name is Cynthia Alvarez, and sorry, I'm holding this down because it's kind of leaning a little.
