San Francisco is slated by PG&E to have a new wireless grid installed starting in July 2010. Lampposts, buildings, and telephone poles will host the wireless repeater infrastructure to serve the new wireless PG&E Smart Meters, which will be installed in every home and business. These devices will add yet another layer of radio frequency radiation (RFR) to our homes and environment and will emit RFR signals throughout the day and night. In light of the lack of FCC safety standards for chronic long-term exposure to RFR and in light of the San Franciscos Precautionary Principle ordinance, we, the undersigned, respectfully request you:

1. Thoroughly investigate the PG&E Smart Meter proposal and potential health and other risks of these devices by holding public hearings;
2. Require PG&E to submit a characterization study of the Smart Meter system planned for San Francisco;
3. Allow customers to "opt out" of program; and
4. Request an immediate moratorium of the installation of Smart Meters and Smart Grid infrastructure to allow time for public hearings.
