The commenter describes alleged premature tower activation documented in city correspondence and coincide…

I urge the Department of Health and Human Services (HHS) to independently review the scientific evidence on radiofrequency (RF) exposure from cell towers, particularly potential non-thermal effects, long-term exposure, and antenna placement near homes, bedrooms, schools, and childcare facilities. Documented premature tower activation Official City of San Mateo correspondence states that Crown Castle energized 19 wireless facilities before receiving required final city inspections and approvals. The City demanded de-energization and identified outstanding construction, electrical, permitting, and compliance issues. In subsequent correspondence following a June 26, 2024 meeting, Assistant City Attorney Linh P. Nguyen reported that only seven of the 19 sites had received final inspections and approval, two had been de-energized for necessary work, and 10 remained essentially unchanged. The City also discovered additional facilities energized without its knowledge, including one with an expired permit and no final inspection or approval. The City warned of further enforcement action. These letters document serious compliance and oversight concerns. While they do not establish health effects, they raise questions about transparency, enforcement, and public safety. Community reports and my experience During this period, members of our community group began reporting headaches, tinnitus, insomnia, anxiety, feeling unwell, and feeling unusually “off.” Some asked whether the towers had been activated. At the time, neither I nor the residents contacting us knew they were operating. After making inquiries, we learned of the City's findings regarding Crown Castle's premature activation of multiple facilities. I cannot prove that RF exposure caused these symptoms, but the timing and similarity of the reports warrant investigation. Around the same time, I developed severe insomnia for the first time in my life. Suddenly, I struggled to sleep, relied on sleep aids, and often awoke feeling unrefreshed. The timing was striking. I offer this experience not as proof of causation, but as a significant health change coinciding with the reported tower activation. I ask that it be considered alongside objective exposure measurements and scientific evidence. Request for scientific review I urge HHS to review the full scientific literature, including studies reporting effects, systematic reviews, and unresolved research questions. Please examine: * Sleep disruption, headaches, tinnitus, neurological function, cognition, and other reported symptoms. * Proposed non-thermal mechanisms, including oxidative stress and cellular signaling, and whether findings are reproducible at real-world exposure levels. * Long-term and cumulative exposure from multiple antennas and wireless sources. * Frequency, modulation, pulsing, duty cycle, beamforming, signal strength, and exposure duration. * Exposure in bedrooms, homes, schools, and childcare facilities, including overnight exposure and potential vulnerabilities of children. * Whether current standards adequately address real-world exposure and evolving scientific evidence. Compliance with outdated existing RF limits should not end scientific inquiry. Agencies should distinguish established adverse health effects from biological findings, plausible hypotheses, and unsupported claims. I respectfully request that the agencies: 1. Review the City's correspondence and examine premature operation before final inspections and approvals. 2. Support independent RF measurements near affected facilities, including in nearby homes, bedrooms, and schools where appropriate. 3. Commission independent research on non-thermal effects, sleep, neurological outcomes, and long-term exposure. 5. Establish appropriate ways to document community health reports and investigate exposure changes. 6. Evaluate reasonable exposure-reduction measures and alternative siting near homes 7. Clarify federal and local responsibilities for permitting, notification, compliance, and enforcement. Conclusion I am not asking agencies to presume that cell towers caused these symptoms. I am asking them to take documented regulatory failures, residents' experiences, and unresolved scientific questions seriously. The City's correspondence documents facilities energized before final approval and additional facilities reportedly activated without its knowledge. During the same general period, residents reported unusual symptoms and I experienced unprecedented insomnia. These circumstances warrant transparent investigation, reliable exposure measurements, and rigorous scientific review. Please evaluate whether current standards adequately reflect the evidence and take appropriate action to strengthen transparency, accountability, and public health protection. Thank you for considering my comment. Attachments: Official City of San Mateo correspondence regarding Crown Castle's premature activation and outstanding inspections and approvals.
