built to the minimum requirements in TSO–C129a. Two examples of these improvements are: (1) A requirement for the receiver to properly account for satellite range error if it is reflected in the User Range Accuracy index (commonly referred to as being ‘‘Selective Availability aware’’); and, (2) requirements to ensure performance is not degraded due to an increasing radio frequency noise environment as other satellite systems become available.

Since 1995, there has been one application for TSOA for TSO–C129a. Therefore, we believe that it is appropriate to cancel TSO–C129a, given the eventual obsolescence of TSO– C129a equipment, and the lack of industry interest in new TSO–C129a product designs.

**Notice of Availability of a Draft Environmental Assessment for a**  **Proposed Airport Traffic Control Tower and Base Building, Toledo Express**  **Airport, Swanton, OH**

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of availability of a draft environmental assessment for a proposed airport traffic control tower and base building, Toledo Express Airport, Swanton, OH.

**SUMMARY :**  The Federal Aviation Administration (FAA) proposes to fund, construct, and operate a new Airport Traffic Control Tower (ATCT) and Base Building at the Toledo Express Airport (TOL), Swanton, Ohio. The existing TOL ATCT and collocated Terminal Radar Approach Control facility are outdated and outmoded. The FAA’s preferred alternative is to construct the ATCT at a location located near the airport terminal building and approximately 1,000 feet west of the existing ATCT facility. The purpose and need of the proposed project is to improve visibility of airport surfaces, provide adequate space to improve operational and administrative efficiency, increase the efficient functionality of the facility, and have the capability to meet future operational and administrative expansion requirements. The FAA has prepared a Draft Environmental Assessment (DEA) in conformance with the requirements of the National Environmental Policy Act of 1969 (NEPA) and FAA Order 1050.1E, Environmental Impacts: Policies and Procedures. The DEA analyzes the potential environmental impacts that may result from construction and operation of the proposed new ATCT and Base Building at the proposed site, as well as the no action alternative (i.e., not constructing and operating the ATCT). Ancillary actions that would be taken in order to maintain optimal operational characteristics include replacement of the current Runway 25 Localizer (LOC) antenna and shelter with a Mark 20 or Mark 20A LOC antenna and shelter, and relocation of the Runway 25 LOC antenna array to a location 1,070 feet outward from the Runway 07 threshold, relocation of the Moving Target Indicator reflector and the upgrade of electronics for the Runway 25 Glide Slope. The DEA is available for public review during a 30–day public comment period at Swanton Pubic Library, 305 Chestnut Street, Swanton, Ohio 43558.

**ADDRESSES :**  The FAA will accept written comments on the DEA until close of business on September 21, 2011. Comments on the DEA may be sent to: Ms. Virginia Marcks, Manager, AJW–C14D, FAA, 2300 East Devon Ave., Des Plaines, IL 60018, fax 847– 294–7698, e-mail virginia.marcks@faa.gov. Copies of the Draft EA on compact disk may be obtained by contacting Ms. Virginia Marcks. Comments received on the DEA during the public comment period will be addressed in a Final Environmental Assessment.
