FEDERAL COMMUNICATIONS COMMISSION 
WASHINGTON 
OFFICE OF 
THE CHAIRMAN 
The Honorable Anna G. Eshoo 
U.S . House of Representatives 
241 Cannon House Office Building 
Washington, D.C. 20515 
Dear Congresswoman Eshoo: 
October 25, 2017 
Thank you for your letter concerning the Commission's Notice of Proposed Rulemaking 
related to radio frequency (RF) exposure limits. I appreciate your concern about the length of this 
proceeding, which involves complex scientific and engineering analysis as well as ongoing 
discussions and negotiations with expert agencies such as the Food and Drug Administration and 
the Occupational Safety and Health Administration. 
When I became Chairman, I directed my staff to review all outstanding rulemakings and 
move ahead expeditiously where there were opportunities for closure, leading to a high volume of 
actions over the last nine months. We continue to focus on several unresolved matters remaining in 
the hopper, and I have asked our staff to work toward concluding this particular matter in a timely 
fashion. 
Please be assured that in the meantime, our Enforcement Bureau will continue to investigate 
complaints and enforce the rules on the books related to rooftop antenna facilities. I also should 
note that while the FCC initiated an inquiry of the existing RF exposure limits, we did not propose 
changing the rules, and comments in this proceeding have been widely split concerning the need to 
amend current regulations. I expect that the FCC's Commissioners will thoroughly deliberate all 
issues before issuing a final rulemaking. 
I appreciate your interest in this matter. Your views are important and a copy of your letter 
will be entered into the record of the proceeding. Please let me know if I can be of any further 
assistance. 
Sincerely,
