Tower Construction Notification System (TCNS)
The Commission's TCNS works to increase communication with Indian Tribes and Native Hawaiian Organizations (NHOs) in the context of the review required by Section 106 of the National Historic Preservation Act (NHPA). It also provides Tribes/NHOs and State Historic Preservation Officers with early notification of proposed towers in order to facilitate compliance with the Commission's rules, and streamline the review process for construction of towers and other Commission undertakings.

Electronic Section-106 System (E-106)
The Commission's E-106 System may be used in completing the review process for proposed constructions of communications facilities under Section 106 of the National Historic Preservation Act (NHPA). E-106 is a voluntary system designed to save users time and resources by automating and expediting the exchange of information and correspondence in the Section 106 process.

Tower construction notification allows companies to voluntarily submit notifications of proposed tower constructions to the FCC. The Commission subsequently provides this information to federally-recognized Indian Tribes, Native Hawaiian Organizations (NHOs), and State Historic Preservation Officers (SHPOs), and allows them to respond directly to the companies if they have concerns about a proposed construction.

The E-106 System enables the real-time referral of information and documented communication among all participating parties, including the FCC. Using the E-106 System, parties proposing to construct communications facilities can now electronically submit the FCC Form 620 or 621 (September 2008 edition) to the SHPO/THPOs using a secure website maintained by the FCC. The new online forms 620 and 621 are substantively the same as the old forms but have been reformatted to accommodate the electronic system. This system also provides electronic notice of the filing to the relevant State Historic Preservation Officer (SHPO), federally recognized Indian Tribes, and other consulting parties, who will be able to access the filings pertinent to them using a secure password. SHPOs and consulting parties can also use the system to comment on filings and otherwise participate in the process, and to access each others’ filings.

The FCC Support Center may be reached from 8:00 A.M to 6:00 P.M. Eastern Time, Monday through Friday.
