62-814.300: General Technical Requirements
62-814.450: Electric and Magnetic Field Standards
PURPOSE AND EFFECT: Implementation of Sections 403.061(30) and 403.523(10), F.S.
SUMMARY: The Department of Environmental Protection is authorized to regulate electric and magnetic fields (EMF) from transmission lines as indicated in Florida Statute 403.061(30). The rule implementing the statute is outdated and requires updates in the following three areas, addressed in this proposed rule: (1) The elimination of a rule exemption for a specific transmission line which was never actually constructed; (2) The inclusion of standards for transmission lines with voltages above 500,000 volts; and (3) The elimination of an annual review and report on the state of science with respect to electromagnetic fields.
SUMMARY OF STATEMENT OF ESTIMATED REGULATORY COSTS: No Statement of Estimated Regulatory Cost was prepared.
Any person who wishes to provide information regarding a statement of estimated regulatory costs, or provide a proposal for a lower cost regulatory alternative must do so in writing within 21 days of this notice.
SPECIFIC AUTHORITY: 403.061(7), 403.523(1) FS.
LAW IMPLEMENTED: 403.061(30), 403.523(14) FS.
IF REQUESTED WITHIN 21 DAYS OF THE DATE OF THIS NOTICE, A HEARING WILL BE SCHEDULED AND ANNOUNCED IN FAW.
THE PERSON TO BE CONTACTED REGARDING THE PROPOSED RULE IS: Mr. Mike Halpin, P.E. at (850)245-8002 or mike.halpin@dep.state.fl.us
THE FULL TEXT OF THE PROPOSED RULE IS:
62-814.100 Intent, Findings, Basis of Standards, and Research Needs.
(1) No change.
(2) Findings. Based on the information available to the Department, the Department makes the following general findings:
(a) The Department has reviewed the present scientific data on the potential for health effects of electric and magnetic fields. The Department has also reviewed data on the existing or potential electric and magnetic field levels near electrical transmission and distribution lines and substations in Further research is needed to determine if there are health effects and the exposure levels at which such effects may occur.
(b) With respect to 60 hertz EMF, reasonable measures include urging more applied research on the potential adverse human health effects of EMF and EMF mitigation techniques; performing a comprehensive review of the state of the science and submitting annual reports to the Environmental Regulation Commission commencing in 1993; reviewing the provisions of this rule not later than July of 1994; and requiring all new and modified transmission lines and substations to meet standards which are achievable through the use of available EMF reduction technology and measures, but in no case to allow any new or modified transmission line or substation, under normal conditions, to cause electric or magnetic field strengths greater than the highest operating voltage and the maximum current rating (MCR) values for existing transmission lines and substations.
(3) No change.
(4) Additional Research Needed. Continued research is needed on the potential adverse human health and welfare effects of 60 hertz EMF and EMF mitigation techniques because existing knowledge is inadequate to confidently conclude that no further action is needed.
(4)(5) Categories of Electrical Facilities. This chapter sets forth three categories of electrical facilities for regulation in regards to the electric and magnetic fields associated with these facilities.
(a) The first category is for existing electrical facilities on which construction was commenced prior to March 21, 1989, and new distribution lines. These facilities will be allowed to operate in accordance with subsection 62-814.400(2), F.A.C.
(b) The second category of electrical facilities is for those which were certified pursuant to Chapter 403, Part Two, Florida Statutes, after April 15, 1988, but before March 21, 1989. These facilities will be subject to specific standards moderated by the individual circumstances of the facility.
(c) The third category is for new transmission lines and substations the construction of which commenced after March 21, 1989.
(5)(6) Effect of Rule. The effect of this chapter is to establish requirements to reasonably protect the public health and welfare from electric and magnetic fields associated with electrical transmission lines, distribution lines and substations.
