                    TITLE 50--WILDLIFE AND FISHERIES
 
CHAPTER IV--JOINT REGULATIONS (UNITED STATES FISH AND WILDLIFE SERVICE, 
 
PART 402_INTERAGENCY COOPERATION_ENDANGERED SPECIES ACT OF 1973, AS 
 
                    Subpart B_Consultation Procedures
 
Sec. 402.12  Biological assessments.

    (a) Purpose. A biological assessment shall evaluate the potential 
effects of the action on listed and proposed species and designated and 
proposed critical habitat and determine whether any such species or 
habitat are likely to be adversely affected by the action and is used in 
determining whether formal consultation or a conference is necessary.
    (b) Preparation requirement. (1) The procedures of this section are 
required for Federal actions that are ``major construction activities''; 
provided that a contract for construction was not entered into or actual 
construction was not begun on or before November 10, 1978. Any person, 
including those who may wish to apply for an exemption from section 
7(a)(2) of the Act, may prepare a biological assessment under

[[Page 820]]

the supervision of the Federal agency and in cooperation with the 
Service consistent with the procedures and requirements of this section. 
An exemption from the requirements of section 7(a)(2) is not permanent 
unless a biological assessment has been prepared.
    (2) The biological assessment shall be completed before any contract 
for construction is entered into and before construction is begun.
    (c) Request for information. The Federal agency or the designated 
non-Federal representative shall convey to the Director either (1) a 
written request for a list of any listed or proposed species or 
designated or proposed critical habitat that may be present in the 
action area; or (2) a written notification of the species and critical 
habitat that are being included in the biological assessment.
    (d) Director's response. Within 30 days of receipt of the 
notification of, or the request for, a species list, the Director shall 
either concur with or revise the list or, in those cases where no list 
has been provided, advise the Federal agency or the designated non-
Federal representative in writing whether, based on the best scientific 
and commercial data available, any listed or proposed species or 
designated or proposed critical habitat may be present in the action 
area. In addition to listed and proposed species, the Director will 
provide a list of candidate species that may be present in the action 
area. Candidate species refers to any species being considered by the 
Service for listing as endangered or threatened species but not yet the 
subject of a proposed rule. Although candidate species have no legal 
status and are accorded no protection under the Act, their inclusion 
will alert the Federal agency of potential proposals or listings.
    (1) If the Director advises that no listed species or critical 
habitat may be present, the Federal agency need not prepare a biological 
assessment and further consultation is not required. If only proposed 
species or proposed critical habitat may be present in the action area, 
then the Federal agency must confer with the Service if required under 
Sec. 402.10, but preparation of a biological assessment is not required 
unless the proposed listing and/or designation becomes final.
    (2) If a listed species or critical habitat may be present in the 
action area, the Director will provide a species list or concur with the 
species list provided. The Director also will provide available 
information (or references thereto) regarding these species and critical 
habitat, and may recommend discretionary studies or surveys that may 
provide a better information base for the preparation of an assessment. 
Any recommendation for studies or surveys is not to be construed as the 
Service's opinion that the Federal agency has failed to satisfy the 
information standard of section 7(a)(2) of the Act.
    (e) Verification of current accuracy of species list. If the Federal 
agency or the designated non-Federal representative does not begin 
preparation of the biological assessment within 90 days of receipt of 
(or concurrence with) the species list, the Federal agency or the 
designated non-Federal representative must verify (formally or 
informally) with the Service the current accuracy of the species list at 
the time the preparation of the assessment is begun.
    (f) Contents. The contents of a biological assessment are at the 
discretion of the Federal agency and will depend on the nature of the 
Federal action. The following may be considered for inclusion:
    (1) The results of an on-site inspection of the area affected by the 
action to determine if listed or proposed species are present or occur 
seasonally.
    (2) The views of recognized experts on the species at issue.
    (3) A review of the literature and other information.
    (4) An analysis of the effects of the action on the species and 
habitat, including consideration of cumulative effects, and the results 
of any related studies.
    (5) An analysis of alternate actions considered by the Federal 
agency for the proposed action.
    (g) Incorporation by reference. If a proposed action requiring the 
preparation of a biological assessment is identical, or very similar, to 
a previous action for which a biological assessment was prepared, the 
Federal agency may fulfill

[[Page 821]]

the biological assessment requirement for the proposed action by 
incorporating by reference the earlier biological assessment, plus any 
supporting data from other documents that are pertinent to the 
consultation, into a written certification that:
    (1) The proposed action involves similar impacts to the same species 
in the same geographic area;
    (2) No new species have been listed or proposed or no new critical 
habitat designated or proposed for the action area; and
    (3) The biological assessment has been supplemented with any 
relevant changes in information.
    (h) Permit requirements. If conducting a biological assessment will 
involve the taking of a listed species, a permit under section 10 of the 
Act (16 U.S.C. 1539) and part 17 of this title (with respect to species 
under the jurisdiction of the FWS) or parts 220, 222, and 227 of this 
title (with respect to species under the jurisdiction of the NMFS) is 
required.
    (i) Completion time. The Federal agency or the designated non- 
Federal representative shall complete the biological assessment within 
180 days after its initiation (receipt of or concurrence with the 
species list) unless a different period of time is agreed to by the 
Director and the Federal agency. If a permit or license applicant is 
involved, the 180-day period may not be extended unless the agency 
provides the applicant, before the close of the 180-day period, with a 
written statement setting forth the estimated length of the proposed 
extension and the reasons why such an extension is necessary.
    (j) Submission of biological assessment. The Federal agency shall 
submit the completed biological assessment to the Director for review. 
The Director will respond in writing within 30 days as to whether or not 
he concurs with the findings of the biological assessment. At the option 
of the Federal agency, formal consultation may be initiated under Sec. 
402.14(c) concurrently with the submission of the assessment.
    (k) Use of the biological assessment. (1) The Federal agency shall 
use the biological assessment in determining whether formal consultation 
or a conference is required under Sec. 402.14 or Sec. 402.10, 
respectively. If the biological assessment indicates that there are no 
listed species or critical habitat present that are likely to be 
adversely affected by the action and the Director concurs as specified 
in paragraph (j) of this section, then formal consultation is not 
required. If the biological assessment indicates that the action is not 
likely to jeopardize the continued existence of proposed species or 
result in the destruction or adverse modification of proposed critical 
habitat, and the Director concurs, then a conference is not required.
    (2) The Director may use the results of the biological assessment in 
(i) determining whether to request the Federal agency to initiate formal 
consultation or a conference, (ii) formulating a biological opinion, or 
(iii) formulating a preliminary biological opinion.
