HHS-OASH-2026-0397-2867 https://www.regulations.gov/comment/HHS-OASH-2026-0397-2867 I would like to know if there’s an increased cancer rate for those people living near electric transmission lines and substations. Also, if there is a risk living near cell phone towers, I live near the Southern California Edison Serrano substation in Orange California where there is a 500 kW transmission line. This substation is still expanding and transmits power 30 miles south to San Onofre, California. There are also several cell phone towers in the same area near our community. In the past few years, I have noticed that several neighbors have died of cancer and many more are coming down with cancer. None of these neighbors smoked and most were very health-conscious. Please investigate as to whether EMFs are causing cancer.
