Airport Master and Contingency Plans

Airport Planning Poster Opens in new windowMagic Valley Regional Airport Master Plan Update

The City of Twin Falls and Twin Falls County is currently updating the Master Plan for the Joslin Field, Magic Valley Regional Airport (TWF).

The Magic Valley Regional Airport plays a critical role in the local economy through commercial air operations and as a provider of multiple aviation services, including fire-fighting, cargo shipment, corporate travel and agriculture.

The airport, operated by the City of Twin Falls, through a grant from the Federal Aviation Administration (FAA), is conducting a Master Plan Update that will help identify needs and growth potential, which will in-turn position the airport to receive funding for improvements and enhancements.

“Community input about the airport’s strengths and opportunities for growth is critical in helping to ensure proposed changes reflect the needs and interests of those that are intended to benefit,” said Bill Carberry, Airport Manager. “Our team will organize multiple opportunities over the next several months for the public to safely participate in the planning process.”

Information regarding the TWF Master Plan Update will be posted on this webpage throughout the master plan process. Opportunities for public involvement are planned throughout 2021.

The first of three planned public open house events took place in December 2020, when information boards regarding the master plan were set up in the airport terminal building for viewing and comments. A link to those boards is provided here [link]. The next public open house is tentatively scheduled for late June 2021. Further details regarding that open house will be posted and advertised when available.

Technical elements of the Master Plan Update are in full swing. As of March 2021, the draft aviation activity forecast has been submitted to the FAA for review and approval. In addition, draft facility requirements have been identified for various airport functional areas, including airfield, terminal, ground transportation, cargo, and other/support facilities. Facility requirements are determined by assessing the future demand for a facility against the existing capacity of the facility, as well as assessing existing conditions of the airport against FAA planning and design guidelines. Once facility requirements have been finalized and reviewed, work will begin (starting in April 2021) on developing and evaluating alternatives for addressing the future requirements. It is anticipated that the TWF Master Plan Update will be completed by the end of 2021.

Ricondo, J-U-B Engineers and the public involvement division of J-U-B, The Langdon Group (TLG), are managing this process. The public is encouraged to contact Bryant Kuechle with TLG (208-739-3048, bk@langdongroupinc.com) with questions, comments and to request to receive future updates.

Magic Valley Regional Airport Tarmac Delay Plan

Emergency Contingency Plan

Magic Valley Regional Airport has prepared this Emergency Contingency Plan pursuant to §42301 of the FAA Modernization and Reform Act of 2012. Questions regarding this plan can be directed to Bill Carberry. Magic Valley Regional Airport is filing this plan with the Department of Transportation because (1) it is a commercial airport or (2) this airport may be used by an air carrier described in USC 42301(a)(1) for diversions.

This plan describes how, following excessive tarmac delays and to the extent practicable, Magic Valley Regional Airport will:

  • Provide for the deplanement of passengers;
  • Provide for the sharing of facilities and make gates available at the airport; and
  • Provide a sterile area following excessive tarmac delays for passengers who have not yet cleared United States Customs and Border Protection (CBP).

Magic Valley Regional Airport has facility constraints that limit our ability to accommodate diverted flights or maintain the airport’s safe operation and strongly encourages aircraft operators to contact the airport at (208) 733-5215 for prior coordination of diverted flights, except in the case of a declared in-flight emergency. Specific facility constraints include the following: limited ramp space along with limited space for aircraft parking at the terminal, one FBO capable of providing fuel that requires a call out between 0300-1330Z, limited airstair availability, our sterile area is limited to approximately 225 people, and we have very limited ability to temporarily accommodate international passenger processing facilities. During diversion events Magic Valley Regional Airport issues NOTAMs regarding its ability to accommodate diverted flights to ensure the safe and efficient operation of the airport and its ability to serve the civil aviation needs of the public during irregular operations events.

Plan to Provide for the Deplanement of Passengers Following Excessive Tarmac Delays

Magic Valley Regional Airport does not operate any of the equipment needed to safely deplane passengers from air carrier aircraft and is, therefore, unable on its own to provide for the deplanement of passengers. Additionally airport personnel are not trained to assist in the deplanement of passengers using equipment owned or operated by air carriers or contract service providers. However, Magic Valley Regional Airport does own a boarding ramp capable of serving the following aircraft: MD80, 737, A319, A320, and 757. We will provide this ramp to the fixed based operator or airline if needed. We will provide a list of airlines, ground handlers, fixed base operators and others who may have the necessary equipment and personnel to safely deplane passengers to airlines as soon as practicable after receiving requests from such airlines experiencing excessive tarmac delays at the contact number listed above.

Plan to Provide for the Sharing of Facilities and Make Gates Available in an Emergency

The gates at Magic Valley Regional Airport are under common use gate leases, or agreements to air carriers and are controlled by the airport. We have a total of three gates available within a sterile area that can accommodate approximately 225 people. We direct our common use air carrier users to make gates and other facilities available to an air carrier seeking to deplane/enplane at a gate to the maximum extent practicable. Magic Valley Regional Airport would direct airlines to our Airport/Facility Directory for guidance on aircraft size limitations.

Plan to Provide a Sterile Area for Passengers Who Have Not Cleared United States Customs and Border Protection

Magic Valley Regional Airport does not have international passenger processing facilities. We have coordinated with regional CBP and law enforcement officials to identify suitable areas and procedures for establishing a temporary sterile area into which international passengers on diverted aircraft who have not yet cleared United States Customs and Border Protection can be deplaned. Our procedure that will allow international passengers who have not yet cleared United States Customs and Border Protection to be deplaned into these sterile areas to the extent practicable is the following:

  1. Airport Operations will contact regional CBP in Boise, ID at (208) 334-9062, or (208) 573-4637.
  2. Airport Operations will contact Twin Falls Police Department.
  3. International passengers will be deplaned into our Passenger Hold Room, where they can remain sterile and cannot co-mingle with non-sterile passengers.
  4. Airport Operations will continue to coordinate with Airline, CBP, and TFPD until the situation is resolved.

Public Access to the Emergency Contingency Plan 

Magic Valley Regional Airport will provide public access to its emergency contingency plan by posting it in a conspicuous location on the airport website.
