New Tower Construction Update Mainly for the Birds

        Radio on FacebookJoin us on Facebook

The US FWS guidelines can be found in full at In short:

1. Construction is strongly encouraged on existing communication towers or other structures.

2. New construct towers are strongly encouraged to be no more than 199' above ground level, using construction techniques that do not require guy wires, and unlighted (if Federal Aviation Administration regulations permit).

3. When constructing multiple towers, providers should consider the impact of each tower and collective towers to threatened and endangered species.

4. If at all possible, new towers should be sited within existing clusters of towers. Towers should not be sited in or near known bird concentration areas, in known migratory or daily movement flyways, or in habitat of threatened or endangered species. Towers should not be sited in areas with a high incidence of fog, mist, and low ceilings.

5. Towers above 199' AGL requiring lights for aviation safety must be constructed with the minimum amount required of pilot warning and obstruction avoidance lighting. Unless otherwise required by the FAA, only white (preferable) or red strobe lights should be used at night, and these should be the minimum number, minimum intensity, and minimum number of flashes per minute allowable.

6. Tower designs using guy wires for support should have daytime visual markers on the wires to prevent collisions.

7. Towers and appended facilities should be sited, designed and constructed so as to avoid or minimize habitat loss within and adjacent to the tower footprint. However, a larger tower footprint is preferable to the use of guy wires in construction.

8. Relocation may be recommended if significant numbers of breeding, feeding, or roosting birds are known to habitually use the proposed tower construction area. If this is not an option, seasonal restrictions on construction may be advisable in order to avoid disturbance during periods of high bird activity.

9. New towers are encouraged to structurally and electrically accommodate the applicant/licensee's antennas and comparable antennas for at least two additional users, unless this design would require the addition of lights or guy wires to an otherwise unlighted and/or unguyed tower.

10. Security lighting for on-ground facilities and equipment should be down-shielded to keep light within the boundaries of the site.

11. Service personnel or researchers from the Communication Tower Working Group should be allowed access to the site.

12. Towers no longer in use or determined to be obsolete should be removed within 12 months of cessation of use.

Streamlined application process

On Sept. 26, 2013, the FCC released a notice of proposed rulemaking to address and update its rules and policies relating to wireless infrastructure builds streamlining environmental and historic preservation review procedures. This proposed rule change(s) are intended to speed up the deployment of new and emerging wireless technologies, they include:

■ An expansion of the current exclusions to EA review. Under the current rules it is permissible to mount new antennas on a building (providing public exposure to RF is below prescribed limits) or existing tower structures. Under the new proposal, there would be no requirement for an EA on new antennas mounted to any type structure, providing the public exposure to RF is below the limit.

■ Categorical exclusion of small cell and DAS (Distributed Antenna Systems) from the Historical Preservation Review process.

■ Waiver of the Environmental notification process for temporary structures that meet the following criteria: Will be in use for 60 days or less; requires notice of construction to the FAA; does not require marking or lighting pursuant to FAA regulations; will be less than 200' in height; and will involve minimal or no excavation.
