Antenna Structure Registration (ASR)
Tower owners must register certain antenna structures with the FCC.  The ASR program helps owners with the registration process.
Tower Construction Notification System (TCNS)
The TCNS offers communications between tower construction companies and Indian Tribes and Native Hawaiian Organizations (NHOs) for the review required by Section 106 of the National Historic Preservation Act (NHPA).  It also offers Tribes/NHOs and State Historic Preservation Officers early notification of proposed towers to ease compliance with the Commission's rules, and streamline the review process.
Electronic Section-106 System (E-106)
The E-106 System may be used to complete 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 which automates and expedites the exchange of information and correspondence.
Under the Antenna Structure Registration (ASR) Program, owners of antenna structures that are taller than 200 feet above ground level or that may interfere with the flight path of a nearby airport must register those structures with the FCC.  Owners must obtain a valid determination of "no hazard to air navigation" from the Federal Aviation Administration (FAA) before registering with the FCC.  The FAA also provides owners with painting and lighting specifications which must be included with their registration prior to construction.
To comply with environmental and historic preservation statutes, the proposed registration must be reviewed for environmental consequences.  If it falls within certain categories, as determined by FCC rules, as having the potential for evironmental effects, an environmental assessment (EA) must be completed and filed with the FCC for review.  The public is offered the opportunity to comment on EAs and the FCC assists the requestor in working with the appropriate local, state, and federal agencies to reach agreement on the mitigation of potential adverse effects.  The filing of an EA is also required when a proposed facility may have a significant impact on historic properties.
If the application is properly made, an ASR number will be assigned immediately.  If an EA is required, the number will be withheld pending resolution of any environmental and historic preservation issues.  When the ASR number is issued, the tower owner is free to construct the antenna structure.  The owner must notify the FCC with 24 hours of completion of construction or cancellation of the project by filing  a form with the FCC.
