Filing coordinates in TCNS and uploading documentation to E initiates statutorily mandated review periods and supports efficient processing. Historic properties are sites, structures, buildings, and objects that are listed on or eligible for listing on the National Register of Historic Places. For Tribal Nations, historic properties include sites and places of cultural and religious significance.
Due to the sensitive nature of these historic properties, these places are often not publicly identified. Tribal Nations have the option to provide this information to the FCC through its Federal Preservation Officer who will ensure that the information is protected throughout the Section process. The Form and Form must be completed by qualified individuals as stated on the forms. Project proponents are encouraged to complete the Form and Form using the E system as the forms are easier to complete and the system contains internal checkpoints to ensure that they are complete and accurate.
Using the E system facilitates FCC access to answer questions or address issues during the Section process. Prior to submitting, the applicant must confirm whether the specific SHPO utilizes E for Section reviews and determine their preferred submittal procedures. Many SHPOs are required by state law to maintain hard copies.
Such referrals may be made through the E system when the Form or has been submitted electronically. The project proponent must engage the SHPO and all consulting parties, including Tribal Nations, about the adverse effect and the potential to mitigate that effect.
To proceed beyond the initial determination of adverse effect, the project proponent must provide the SHPO and all consulting parties with an alternatives analysis or plan that demonstrates that the proposed location is the only feasible location due to engineering requirements. The FCC may review these plans. In addition, the project proponent and the consulting parties should develop appropriate mitigation measures.
Mitigation measures should have a public benefit directly tied to the adverse effect. Payments of cash are not appropriate. Wireless Infrastructure Second Report and Order. The NHPA requires that federal agencies must consult with any federally-recognized Tribal Nation that attaches religious and cultural significant to historic properties affected by an undertaking in carrying out the Section review process.
Uploading the relevant form to the E system will notify Tribal Nations that the materials are ready for review and track the statutorily mandated day review period. Tribal recipients can respond directly to the companies if they have concerns about a proposed construction. In , the ACHP issued a Program Comment to facilitate the deployment of broadband by eliminating duplicative Section reviews for projects regulated by the Commission but funded or otherwise subject to involvement by another federal agency.

In order to minimize such incidents and bring about efficiencies in the day-to-day Operations, Telecom tower companies evolved the concept of a 'Tower Operations Center'.
The Center also maintains a whole lot of data on the status of the companies towers across the country. Right from the health of the equipment, down to the last service alert, every single piece of information is stored and monitored by a large team of qualified personnel, with the help of sophisticated Software and equipment. For efficient operations, the Towers need to be maintained, serviced, repaired, overhauled and upgraded from time to time.
In order to streamline and simplify the process, all this is managed from a single centralized location that operates 24x7, Called the TOC Tower Operations center. Subsequently, based on the location, nature of the problem, and availability of personnel, the Tickets are forwarded to the concerned technician on his mobile phone. Actions Shares.
