January 22, 2007 – Federal Register Recent Federal Regulation Documents

The Coast Guard is changing the operating regulations governing the Cortez (SR 684) Bridge and the Anna Maria (SR 64) (Manatee Avenue West) Bridge across the Gulf Intracoastal Waterway, miles 87.4 and 89.2 in Anna Maria, Manatee County, Florida. This rule will require the drawbridges to open on signal, except during daytime hours when the bridge will be on a 30-minute schedule during the winter months and a 20-minute schedule for all other months.

The Saint Lawrence Seaway Development Corporation (SLSDC) and the St. Lawrence Seaway Management Corporation (SLSMC) of Canada, under international agreement, jointly publish and presently administer the St. Lawrence Seaway Regulations and Rules (Practices and Procedures in Canada) in their respective jurisdictions. Under agreement with the SLSMC, the SLSDC is amending the joint regulations by updating the Seaway Regulations and Rules in various categories. The changes update the following sections of the Regulation and Rules: Condition of Vessels; Preclearance and Security for Tolls; Seaway Navigation; Dangerous Cargo; and, General. These amendments are necessary to take account of updated procedures and will enhance the safety of transits through the Seaway. Several of the amendments are merely editorial or for clarification of existing requirements.

We are amending the Oriental fruit fly regulations by adding the Santa Ana area of Orange County, CA, to the list of quarantined areas and restricting the interstate movement of regulated articles from that area. In addition, we are removing a portion of San Bernardino County, CA, from the list of quarantined areas and removing restrictions on the interstate movement of regulated articles from that area. These actions are necessary to prevent the artificial spread of Oriental fruit fly to noninfested areas of the United States and to remove restrictions that are no longer necessary on the interstate movement of regulated articles from areas where Oriental fruit fly has been eradicated.

This rule establishes final free and restricted percentages for domestic inshell hazelnuts for the 2006-2007 marketing year under the Federal marketing order for hazelnuts grown in Oregon and Washington. The final free and restricted percentages are 8.2840 percent and 91.7160 percent, respectively. The percentages allocate the quantity of domestically produced hazelnuts which may be marketed in the domestic inshell market (free) and the quantity of domestically produced hazelnuts that must be disposed of in outlets approved by the Board (restricted). Volume regulation is intended to stabilize the supply of domestic inshell hazelnuts to meet the limited domestic demand for such hazelnuts with the goal of providing producers with reasonable returns. This rule was recommended unanimously by the Hazelnut Marketing Board (Board), which is the agency responsible for local administration of the marketing order.

DoD is proposing to amend the Defense Federal Acquisition Regulation Supplement (DFARS) to address requirements for validation of Taxpayer Identification Numbers as part of the Central Contractor Registration process. The proposed changes are consistent with changes made to the Federal Acquisition Regulation.

DoD is proposing to amend the Defense Federal Acquisition Regulation Supplement (DFARS) to address training requirements that apply to contractor personnel who perform information assurance functions for DoD. The rule provides that contractor personnel accessing information systems must meet applicable training and certification requirements.

DoD has issued an interim rule amending the Defense Federal Acquisition Regulation Supplement (DFARS) to provide a single reference to DoD-unique acquisition flexibilities that may be used to facilitate and expedite acquisitions of supplies and services during emergency situations.

The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) Dart 528, 529, 532, 535, 542, and 555 series turboprop engines. This AD requires a dimensional inspection of the intermediate pressure turbine (IPT) disk or an ultrasonic inspection of the seal arm contact between the high pressure turbine (HPT) and the IPT disk seal arm and rework or replacement of the IPT disk if wear outside acceptable limits is found. This AD results from reports of a number of HPT disk failures, some of which resulted in portions of the HPT disk being released. We are issuing this AD to prevent HPT disk failure, which can result in an uncontained engine failure and damage to the airplane.

The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce plc (RR) RB211 Trent 700 series turbofan engines. That AD currently requires initial and repetitive borescope inspections of the high pressure-and-intermediate pressure (HP-IP) turbine internal and external oil vent tubes for coking and carbon buildup, and cleaning or replacing the vent tubes if necessary. This AD requires the same actions but uses more stringent tube replacement criteria than the previous AD. This AD results from a recent incident where an RB211 Trent 700 series turbofan engine had an oil vent tube rupture as a result of blockage, leading to significant loss of engine oil. The incident indicates that further measures are necessary to control carbon buildup in the oil vent tubes. We are issuing this AD to prevent internal oil fires due to coking and carbon buildup, that could cause uncontained engine failure and damage to the airplane.
