on voluntary reporting of unsafe events; and (d) opinions and observations about the operation of C 3RS at their work site. It is estimated that the survey will take no more than 30 minutes to complete for a maximum total burden of 1,800 hours (3,600 respondents*30 minutes/ 60 = 1,800 hours). The survey will be administered at three pilot sites within three to four years resulting in an average annual burden of 600 hours (1,800/3).

**ADDRESSES :**  The agency seeks public comments on its proposed information collection. Comments should address whether the information will have practical utility; the accuracy of the agency’s estimate of the burden of the proposed information collection; ways to enhance the quality, utility and clarity of the information to be collected; and ways to minimize the burden of the collection of information on respondents, including the use of automated collection techniques or other forms of information technology. Send comments to the Office of Information and Regulatory Affairs, Office of Management and Budget, 725– 17th Street, NW., Washington, DC 20503, Attention: RITA/BTS Desk Officer.

Issued in Washington, DC, on this 16th day of July 2010. Steven D. Dillingham, Director, Bureau of Transportation Statistics, Research and Innovative Technology Administration.

**ACTION :**  Notice of cancellation of: (1) Loran-C navigation system Technical Standard Orders (TSO); and (2) the revocation of Loran-C navigation system TSO Authorizations (TSOA), and request for public comment.

**SUMMARY :**  This notice announces the cancellation of Technical Standard Order (TSO) C–60, Airborne Area Navigation Equipment Using Loran-C inputs and all subsequent revisions. The effect of the cancelled TSOs will result in the revocation of all TSOAs issued for the production of those navigational systems. These actions are necessary because the Loran-C Navigation System ceased operation on February 8, 2010. **DATES :**  Comments must be received on or before August 23, 2010

**FOR FURTHER INFORMATION CONTACT :**  Mr. Kevin Bridges, AIR–130, Federal Aviation Administration, 470 L’Enfant Plaza, Suite 4102, Washington, DC 20024. Telephone (202) 385–4627, fax (202) 385–4651, e-mail to: kevin.bridges@faa.gov.

**SUPPLEMENTARY INFORMATION :** 
Comments Invited

You are invited to comment on the cancellation of the TSO and the revocation of the associated TSOAs by submitting written data, views, or arguments to the above address. Comments received may be examined, both before and after the closing date, at the above address, weekdays except federal holidays, between 8:30 a.m. and 4:30 p.m. The Director, Aircraft Certification Service, will consider all comments received on or before the closing date. Background

The Loran-C navigation system ceased transmitting usable signals on February 8, 2010. Because the Loran-C system ceased operation, the FAA intends to cancel all Loran-C Technical Standard Orders and revoke all associated Technical Standard Order Authorizations (TSOA).

The FAA database contains one (1) specific TSO requiring the Loran-C system as a means of navigation, and numerous TSOAs issued for the design and manufacture of Loran-C avionics equipment. This announcement serves as notice to all Loran-C TSOA holders that the FAA intends to cancel all TSOs (including active historical TSOs) and revoke all TSOAs for Loran-C avionics equipment.

Issued in Washington, DC, on July 13,
2010. Susan J.M. Cabler, Assistant Manager, Aircraft Engineering Division, Aircraft Certification Service.

**Notice of Availability of a Final Environmental Assessment (Final EA)**  **and a Finding of No Significant Impact (FONSI)/Record of Decision (ROD) for**  **the Proposed ORD Airport Surveillance Radar, Model 9, West Chicago, IL** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT. **ACTION :**  Notice of Availability of a Final Environmental Assessment (Final EA) and Finding of No Significant Impact (FONSI)/Record of Decision (ROD) for the Proposed ORD Airport Surveillance Radar, Model 9, West Chicago, Illinois.

**SUMMARY :**  The Federal Aviation Administration (FAA) is issuing this notice to advise the public that the FAA has prepared, and approved on May 4, 2010, a Finding of No Significant Impact (FONSI)/Record of Decision (ROD) based on the Final Environmental Assessment (Final EA) for the Proposed ORD Airport Surveillance Radar, Model 9 (ASR–9), in West Chicago, Illinois. The FAA prepared the Final EA in accordance with the National Environmental Policy Act and the FAA’s regulations and guidelines for environmental documents and was signed on April 16, 2010. Copies of the FONSI/ROD and/or Final EA are available by contacting Ms. Virginia Marcks through the contact information provided below.

**FOR FURTHER INFORMATION CONTACT :**  Ms. Virginia Marcks, Manager, Infrastructure Engineering Center, AJW–C14D, Federal Aviation Administration, 2300 East Devon Avenue, Des Plaines, Illinois 60018. Telephone number: (847) 294–
7494.

**SUPPLEMENTARY INFORMATION :**  The Final EA evaluated the construction and operation of the new ORD ASR–9 at DuPage Airport (DPA) in West Chicago, Illinois. The purpose and need of the ORD West ASR–9 is to enhance air traffic management for ORD to achieve the benefits of providing expanded radar coverage that would allow terminal air traffic control for additional new approach routes (West High and Wide approaches), as evaluated and approved in the O’Hare Modernization Environmental Impact Statement (EIS) and ROD.

The proposed ASR–9 would be constructed at a 200 foot (ft) × 200 ft area located west of the intersection of Kress Road and Western Drive on land leased from DPA. The total height of the ASR–9 tower structure would be 116 ft above ground level. The ASR–9 system consists of a tower, a rotating radar sail that transmits and receives the radio signals, an equipment building housing radar equipment, and an emergency generator with an aboveground storage tank for diesel fuel. One moving target indicator reflector and two Calibration and Performance Monitoring Equipment modules would be located at least 1 nautical mile from the preferred ASR– 9 site. The FAA would construct a 24 ft wide × 400 ft long access road to the
