Modified Base (1% annual-chance) Flood Elevations (BFEs) are finalized for the communities listed below. These modified BFEs will be used to calculate flood insurance premium rates for new buildings and their contents.

Base (1% annual-chance) Flood Elevations and modified Base Flood Elevations (BFEs) are made final for the communities listed below. The BFEs and modified BFEs are the basis for the floodplain management measures that each community is required either to adopt or to show evidence of being already in effect in order to qualify or remain qualified for participation in the National Flood Insurance Program (NFIP).

This action establishes Class E airspace at Nicholasville, KY. Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAP) Runway (RWY) 9 and RWY 27 have been developed for Lucas Field Airport. As a result, controlled airspace extending upward from 700 feet Above Ground Level (AGL) is needed to contain the SIAPs and for Instrument Flight Rules (IFR) operations at Lucas Field Airport. The operating status of the airport will change from Visual Flight Rules (VFR) to include IFR operations concurrent with the publication of the SIAP.

This notice proposes to establish Class D airspace at Bay St. Louis, MS. A federal contract tower with a weather reporting system is being constructed at Stennis International Airport. Therefore, the airport will meet criteria for Class D airspace. Class D surface area airspace is required when the control tower is open to contain Standard Instrument Approach Procedures (SIAPs) and other Instrument Flight Rules (IFR) operations at the airport. This action would establish Class D airspace extending upward from the surface to and including 2,500 feet MSL within a 4.2-mile radius of the airport.

On January 3, 2005, the FAA published final rules implementing the Cape Town Treaty. on February 17, 2006, the FAA published a notice advising that the Cape Town Treaty becomes effective for the United States on March 1, 2006. The FAA is publishing this document to advise interested persons of certain procedures in the Aircraft Registration Branch related to the Cape Town Treaty.

The Department of the Navy is amending its certifications and exemptions under the International Regulations for Preventing Collisions at Sea, 1972 (72 COLREGS), to reflect that the Deputy Assistant Judge Advocate General of the Navy (Admiralty and Maritime Law) has determined that Causeway Ferry Power Modules (CFPM) and Warping Tugs (WT) are vessels of the Navy which, due to their special construction and purpose, cannot fully comply with certain provisions of the 72 COLREGS without interfering with their special function as naval ships. The intended effect of this rule is to warn mariners in waters where 72 COLREGS apply.

EPA is approving a State Implementation Plan (SIP) revision submitted by the state of Iowa for the purpose of establishing exemptions for indoor sources of air pollution that are not directly vented to the outside but have emissions that leave the building through doors, vents or other means. This revision also clarifies that the permitting exemptions do not relieve the owner or operator of any source from any obligation to comply with any other applicable requirements. The state has determined that air pollution emissions from this equipment are negligible and these exemptions are likely to result in no significant impact on human health or the environment.

On November 25, 2005 (70 FR 70999), EPA published a direct final rule approving revisions to Indiana's sulfur dioxide (SO2) state implementation plan (SIP) for sources located in Dearborn County. These revisions to the SIP include: revising SO2 emission limits for existing sources; making minor corrections by removing obsolete rule language; and updating information for sources listed in the rule. On November 25, 2005 (70 FR 71071), EPA also published a proposed rule on this revision. The direct final rule stated that if EPA received an adverse comment, EPA would withdraw the direct final rule and address all public comments received in a subsequent final rule based on the proposed rule. EPA received an adverse comment and removed the direct final rule on January 27, 2006 (71 FR 4490). This rule responds to the comments received and announces EPA's final action.

We, the U.S. Fish and Wildlife Service (Service), announce a 90-day finding on a petition to list the Black Hills mountainsnail (Oreohelix cooperi) as threatened or endangered under the Endangered Species Act of 1973, as amended (ESA). We find the petition does not provide substantial scientific information indicating that listing the Black Hills mountainsnail may be warranted. Therefore, we will not be initiating a further status review in response to this petition. We ask the public to submit to us any new information that becomes available concerning the status of the species or threats to it.

The Occupational Safety and Health Administration (OSHA) is amending the existing standard which limits occupational exposure to hexavalent chromium (Cr(VI)). OSHA has determined based upon the best evidence currently available that at the current permissible exposure limit (PEL) for Cr(VI), workers face a significant risk to material impairment of their health. The evidence in the record for this rulemaking indicates that workers exposed to Cr(VI) are at an increased risk of developing lung cancer. The record also indicates that occupational exposure to Cr(VI) may result in asthma, and damage to the nasal epithelia and skin. The final rule establishes an 8-hour time-weighted average (TWA) exposure limit of 5 micrograms of Cr(VI) per cubic meter of air (5 [mu]g/m\3\). This is a considerable reduction from the previous PEL of 1 milligram per 10 cubic meters of air (1 mg/10 m\3\, or 100 [mu]g/ m\3\) reported as CrO3, which is equivalent to a limit of 52 [mu]g/m\3\ as Cr(VI). The final rule also contains ancillary provisions for worker protection such as requirements for exposure determination, preferred exposure control methods, including a compliance alternative for a small sector for which the new PEL is infeasible, respiratory protection, protective clothing and equipment, hygiene areas and practices, medical surveillance, recordkeeping, and start-up dates that include four years for the implementation of engineering controls to meet the PEL. The final standard separately regulates general industry, construction, and shipyards in order to tailor requirements to the unique circumstances found in each of these sectors. The PEL established by this rule reduces the significant risk posed to workers by occupational exposure to Cr(VI) to the maximum extent that is technologically and economically feasible.
