  §  1.1307   Actions that may have a significant environmental effect, for which
Environmental Assessments (EAs) must be prepared.

   Link to an amendment published at  85 FR 18142 , Apr. 1, 2020.

   Link to a correction of the above amendment published at  85 FR 33578 ,
   June 2, 2020.

   (a) Commission actions with respect to the following types of
   facilities may significantly affect the environment and thus require
   the preparation of EAs by the applicant (see § § 1.1308 and 1.1311) and
   may require further Commission environmental processing (see § § 1.1314,
   1.1315 and 1.1317):

   (1) Facilities that are to be located in an officially designated
   wilderness area.

   (2) Facilities that are to be located in an officially designated
   wildlife preserve.

   (3) Facilities that: (i) May affect listed threatened or endangered
   species or designated critical habitats; or (ii) are likely to
   jeopardize the continued existence of any proposed endangered or
   threatened species or likely to result in the destruction or adverse
   modification of proposed critical habitats, as determined by the
   Secretary of the Interior pursuant to the Endangered Species Act of
   1973.

   Note: The list of endangered and threatened species is contained in 50
   CFR 17.11, 17.22, 222.23(a) and 227.4. The list of designated critical
   habitats is contained in 50 CFR 17.95, 17.96 and part 226. To ascertain
   the status of proposed species and habitats, inquiries may be directed
   to the Regional Director of the Fish and Wildlife Service, Department
   of the Interior.

   (4) Facilities that may affect districts, sites, buildings, structures
   or objects, significant in American history, architecture, archeology,
   engineering or culture, that are listed, or are eligible for listing,
   in the National Register of Historic Places (see 54 U.S.C. 300308; 36
   CFR parts 60 and 800), and that are subject to review pursuant to
   section 1.1320 and have been determined through that review process to
   have adverse effects on identified historic properties.

   (5) Facilities that may affect Indian religious sites.

   (6) Facilities to be located in floodplains, if the facilities will not
   be placed at least one foot above the base flood elevation of the
   floodplain.

   (7) Facilities whose construction will involve significant change in
   surface features (e.g., wetland fill, deforestation or water
   diversion). (In the case of wetlands on Federal property, see Executive
   Order 11990.)

   (8) Antenna towers and/or supporting structures that are to be equipped
   with high intensity white lights which are to be located in residential
   neighborhoods, as defined by the applicable zoning law.

   (b) In addition to the actions listed in paragraph (a) of this section,
   Commission actions granting construction permits, licenses to transmit
   or renewals thereof, equipment authorizations or modifications in
   existing facilities, require the preparation of an Environmental
   Assessment (EA) if the particular facility, operation or transmitter
   would cause human exposure to levels of radiofrequency radiation in
   excess of the limits in § § 1.1310 and 2.1093 of this chapter.
   Applications to the Commission for construction permits, licenses to
   transmit or renewals thereof, equipment authorizations or modifications
   in existing facilities must contain a statement confirming compliance
   with the limits unless the facility, operation, or transmitter is
   categorically excluded, as discussed below. Technical information
   showing the basis for this statement must be submitted to the
   Commission upon request. Such compliance statements may be omitted from
   license applications for transceivers subject to the certification
   requirement in § 25.129 of this chapter.

   (1) The appropriate exposure limits in § § 1.1310 and 2.1093 of this
   chapter are generally applicable to all facilities, operations and
   transmitters regulated by the Commission. However, a determination of
   compliance with the exposure limits in § 1.1310 or § 2.1093 of this
   chapter (routine environmental evaluation), and preparation of an EA if
   the limits are exceeded, is necessary only for facilities, operations
   and transmitters that fall into the categories listed in table 1, or
   those specified in paragraph (b)(2) of this section. All other
   facilities, operations and transmitters are categorically excluded from
   making such studies or preparing an EA, except as indicated in
   paragraphs (c) and (d) of this section. For purposes of table 1,
   building-mounted antennas means antennas mounted in or on a building
   structure that is occupied as a workplace or residence. The term power
   in column 2 of table 1 refers to total operating power of the
   transmitting operation in question in terms of effective radiated power
   (ERP), equivalent isotropically radiated power (EIRP), or peak envelope
   power (PEP), as defined in § 2.1 of this chapter. For the case of the
   Cellular Radiotelephone Service, subpart H of part 22 of this chapter;
   the Personal Communications Service, part 24 of this chapter and the
   Specialized Mobile Radio Service, part 90 of this chapter, the phrase
   total power of all channels in column 2 of table 1 means the sum of the
   ERP or EIRP of all co-located simultaneously operating transmitters
   owned and operated by a single licensee. When applying the criteria of
   table 1, radiation in all directions should be considered. For the case
   of transmitting facilities using sectorized transmitting antennas,
   applicants and licensees should apply the criteria to all transmitting
   channels in a given sector, noting that for a highly directional
   antenna there is relatively little contribution to ERP or EIRP
   summation for other directions.

   of this chapter by finite difference time domain (FDTD) computational
   modeling or laboratory measurement techniques. Where a showing is based
   on computational modeling, the Commission retains the discretion to
   request that supporting documentation and/or specific absorption rate
   (SAR) measurement data be submitted.

   (v) All other mobile, portable, and unlicensed transmitting devices are
   categorically excluded from routine environmental evaluation for RF
   exposure under § § 2.1091, 2.1093 of this chapter except as specified in
   paragraphs (c) and (d) of this section.

   (3) In general, when the guidelines specified in § 1.1310 are exceeded
   in an accessible area due to the emissions from multiple fixed
   transmitters, actions necessary to bring the area into compliance are
   the shared responsibility of all licensees whose transmitters produce,
   at the area in question, power density levels that exceed 5% of the
   power density exposure limit applicable to their particular transmitter
   or field strength levels that, when squared, exceed 5% of the square of
   the electric or magnetic field strength limit applicable to their
   particular transmitter. Owners of transmitter sites are expected to
   allow applicants and licensees to take reasonable steps to comply with
   the requirements contained in § 1.1307(b) and, where feasible, should
   encourage co-location of transmitters and common solutions for
   controlling access to areas where the RF exposure limits contained in
   § 1.1310 might be exceeded.

   (i) Applicants for proposed (not otherwise excluded) transmitters,
   facilities or modifications that would cause non-compliance with the
   limits specified in § 1.1310 at an accessible area previously in
   compliance must submit an EA if emissions from the applicant's
   transmitter or facility would result, at the area in question, in a
   power density that exceeds 5% of the power density exposure limit
   applicable to that transmitter or facility or in a field strength that,
   when squared, exceeds 5% of the square of the electric or magnetic
   field strength limit applicable to that transmitter or facility.

   (ii) Renewal applicants whose (not otherwise excluded) transmitters or
   facilities contribute to the field strength or power density at an
   accessible area not in compliance with the limits specified in § 1.1310
   must submit an EA if emissions from the applicant's transmitter or
   facility results, at the area in question, in a power density that
   exceeds 5% of the power density exposure limit applicable to that
   transmitter or facility or in a field strength that, when squared,
   exceeds 5% of the square of the electric or magnetic field strength
   limit applicable to that transmitter of facility.

   (c) If an interested person alleges that a particular action, otherwise
   categorically excluded, will have a significant environmental effect,
   the person shall submit to the Bureau responsible for processing that
   action a written petition setting forth in detail the reasons
   justifying or circumstances necessitating environmental consideration
   in the decision-making process. (See § 1.1313). The Bureau shall review
   the petition and consider the environmental concerns that have been
   raised. If the Bureau determines that the action may have a significant
   environmental impact, the Bureau will require the applicant to prepare
   an EA (see § § 1.1308 and 1.1311), which will serve as the basis for the
   determination to proceed with or terminate environmental processing.

   (d) If the Bureau responsible for processing a particular action,
   otherwise categorically excluded, determines that the proposal may have
   a significant environmental impact, the Bureau, on its own motion,
   shall require the applicant to submit an EA. The Bureau will review and
   consider the EA as in paragraph (c) of this section.

   Note to paragraph (d): Pending a final determination as to what, if
   any, permanent measures should be adopted specifically for the
   protection of migratory birds, the Bureau shall require an
   Environmental Assessment for an otherwise categorically excluded action
   involving a new or existing antenna structure, for which an antenna
   structure registration application (FCC Form 854) is required under
   part 17 of this chapter, if the proposed antenna structure will be over
   450 feet in height above ground level (AGL) and involves either:

   1. Construction of a new antenna structure;

   2. Modification or replacement of an existing antenna structure
   involving a substantial increase in size as defined in paragraph
   I(C)(1)(3) of Appendix B to part 1 of this chapter; or

   3. Addition of lighting or adoption of a less preferred lighting style
   as defined in § 17.4(c)(1)(iii) of this chapter. The Bureau shall
   consider whether to require an EA for other antenna structures subject
   to § 17.4(c) of this chapter in accordance with § 17.4(c)(8) of this
   chapter. An Environmental Assessment required pursuant to this note
   will be subject to the same procedures that apply to any Environmental
   Assessment required for a proposed tower or modification of an existing
   tower for which an antenna structure registration application (FCC Form
   854) is required, as set forth in § 17.4(c) of this chapter.

   (e) No State or local government or instrumentality thereof may
   regulate the placement, construction, and modification of personal
   wireless service facilities on the basis of the environmental effects
   of radio frequency emissions to the extent that such facilities comply
   with the regulations contained in this chapter concerning the
   environmental effects of such emissions. For purposes of this
   paragraph:

   (1) The term personal wireless service means commercial mobile
   services, unlicensed wireless services, and common carrier wireless
   exchange access services;

   (2) The term personal wireless service facilities means facilities for
   the provision of personal wireless services;

   (3) The term unlicensed wireless services means the offering of
   telecommunications services using duly authorized devices which do not
   require individual licenses, but does not mean the provision of
   direct-to-home satellite services; and

   (4) The term direct-to-home satellite services means the distribution
   or broadcasting of programming or services by satellite directly to the
   subscriber's premises without the use of ground receiving or
   distribution equipment, except at the subscriber's premises or in the
   uplink process to the satellite.
