**SUPPLEMENTARY INFORMATION :** 

Background: In the ANPR, EPA described and invited comment from all interested parties on the data available for evaluating lead emissions, ambient concentrations and potential exposure to lead from the use of leaded aviation gasoline (avgas) in piston-engine powered aircraft. The ANPR is one of the steps EPA has taken in response to a petition submitted by Friends of the Earth (FOE) requesting that EPA find endangerment from and regulate lead emitted by piston-engine aircraft, or if insufficient information exists, to commence a study. In addition to describing and inviting comment on the current data, the ANPR also describes considerations regarding emission engine standards and requests comment on approaches for transitioning the piston-engine fleet to unleaded avgas.

Extension of Comment Period: EPA received requests for an extension of the ANPR comment period that are available in the docket for this rule (EPA–HQ–OAR–2007–0294). After considering the requests, EPA has determined that a 60-day extension of the comment period would provide the public adequate time to provide meaningful comment on the ANPR. Accordingly, the public comment period for the ANPR is extended until August 27, 2010. EPA does not anticipate any further extension of the comment period at this time.

**Endangered and Threatened Wildlife and Plants; Listing the Cumberland**  **Darter, Rush Darter, Yellowcheek Darter, Chucky Madtom, and Laurel**  **Dace as Endangered Throughout Their Ranges** 

**AGENCY :**  Fish and Wildlife Service,
Interior.

**ACTION :**  Proposed rule; request for public comments.

**SUMMARY :**  We, the U.S. Fish and Wildlife Service (Service), propose to list the Cumberland darter ( Etheostoma

susanae ), rush darter ( Etheostoma phytophilum ), yellowcheek darter ( Etheostoma moorei), chucky madtom ( Noturus crypticus ), and laurel dace ( Phoxinus saylori) as endangered under the Endangered Species Act of 1973, as amended (Act). If we finalize this rule as proposed, it would extend the Act’s protections to these species throughout their ranges, including, Cumberland darter in Kentucky and Tennessee, rush darter in Alabama, yellowcheek darter in Arkansas, and chucky madtom and laurel dace in Tennessee. We have determined that critical habitat for these species is prudent, but not determinable at this time.

**DATES :**  We will consider comments we receive on or before August 23, 2010. We must receive requests for public hearings, in writing, at the address shown in the **ADDRESSES** section by August 9, 2010.

**SUPPLEMENTARY INFORMATION :**  Request for Public Comments

We intend that any final action resulting from this proposed rule will be based on the best scientific and commercial data available and as accurate and effective as possible. Therefore, we request comments or information from the public, other concerned governmental agencies, the scientific community, industry, or any other interested party concerning this proposed rule. We particularly seek comments concerning:

(1) Biological, commercial trade, or other relevant data concerning any threats (or lack thereof) to these species and regulations that may be addressing those threats;

(2) Additional information concerning the ranges, distribution, and population size of these species, including the locations of any additional populations of the species;

(3) Any additional information on the biological or ecological requirements of the species;

(4) Current or planned activities in the areas occupied by the species and possible impacts of these activities on the species and their habitat;

(5) Potential effects of climate change on the species and their habitats;

(6) The reasons why areas should or should not be designated as critical habitat as provided by section 4 of the Act (16 U.S.C. 1531, et seq. ), including whether the benefits of designation would outweigh threats to the species that designation could cause (e.g., exacerbation of existing threats, such as overcollection), such that the designation of critical habitat is prudent; and .

(7) Specific information on:

• What areas contain physical and biological features essential for the conservation of the species;

• What areas are essential to the conservation of the species; and

• Special management considerations or protection that proposed critical habitat may require. Please note that submissions merely stating support for or opposition to the action under consideration without providing supporting information, although noted, will not be considered in making a determination, as section 4(b)(1)(A) of the Act directs that determinations as to whether any species is a threatened or endangered species mush be made ‘‘ solely on the basis of the best scientific and commercial data available. ’’
