Article VIII — Radio Frequency Exposure Review
Brawley Municipal Code · 2026-09 edition · updated 2026-10-02 · Brawley
Sec. 8C.9. - Radio-frequency exposure review.¶
An RF Environmental Evaluation Report shall be prepared for any proposed communication facility meeting the specifications below. In order for a proposed facility that requires an RF Environmental Evaluation Report to be approved, the report must demonstrate that RF emissions from the facility in combination with existing RF emissions from nearby facilities will meet the current FCC adopted exposure standard.
Facilities Requiring an RE Environmental Evaluation Report. Wireless communication facilities meeting any of the following criteria require an RF Environmental Evaluation Report before they may be permitted under these regulations:
a.
Facilities described in Table I Section 1.1307 "Transmitters, Facilities and Operations Subject to Routine Environmental Evaluation" of the FCC Rules and Regulations, 47 C.F.R. § 1.1307, or any superseding regulation.
b.
Facilities proposed to be installed within fifty feet of an existing communication facility.
c.
Facilities with one or more antenna to be installed less than ten feet above any area that is accessible to untrained workers or the public.
Evaluation Report Requirements. The RF Environmental Evaluation Report shall meet the following requirements:
a.
The RF Environmental Evaluation Report is subject to approval of the planning director.
b.
The RF Environmental Evaluation Report shall be prepared by a radio-frequency exposure professional.
c.
The RF Environmental Evaluation Report shall explicitly state that "operation of the proposed facility in addition to other ambient RF emission levels will not exceed current FCC-adopted standards with regard to human exposure in controlled and uncontrolled areas as defined by the FCC."
d.
Assumptions utilized for the calculations of RF exposure shall be conservative in nature and at a minimum be in accordance with the most recent FCC guidance on assessment of RF exposures.
e.
The RF Environmental Evaluation Report shall compare RF measurements and/or calculations of RF exposure to the applicable FCC exposure standard. The comparison shall include the power density in micro-watts per square centimeter and as a percentage of the applicable FCC exposure standard.
f.
RF field measurements of power density of the proposed facility and/or surrounding facilities are required to be included in the RF Environmental Evaluation Report when:
(i)
Adequate technical information regarding other wireless communication facilities that may substantially contribute to RF exposure at the subject site is unavailable;
(ii)
Calculations of RF exposure indicate the possibility of exposures in excess of the FCC exposure standard; or
(iii)
So directed by the planning director because of concerns about the number of near-by facilities.
g.
All required RF field measurements shall be performed by a radio-frequency exposure professional. Evidence must be submitted showing that the testing instrument(s) used were calibrated within their manufacturer's suggested periodic calibration interval, and that the calibration is by methods traceable to the National Institute of Standards and Technology. Measurements shall be performed in compliance with FCC guidance regarding the measurement of RF emissions and shall be conducted during normal business hours on a non-holiday weekday.
h.
The planning director or his/her designee may monitor the performance of testing required for preparation of the RF Environmental Evaluation Report. The cost of such monitoring shall be borne by the operator.
i.
For an amateur radio station facility, self-certification of compliance by the amateur radio station license is acceptable if permitted by FCC regulations and conducted under standards and procedures set forth by the FCC.
