PART 1506_OTHER REQUIREMENTS OF NEPA--Table of Contents
 
Sec.  1506.12  Effective date.

    The effective date of these regulations is July 30, 1979, except 
that for agencies that administer programs that qualify under section 
102(2)(D) of the Act or under section 104(h) of the Housing and 
Community Development Act of 1974 an additional four months shall be 
allowed for the State or local agencies to adopt their implementing 
procedures.
    (a) These regulations shall apply to the fullest extent practicable 
to ongoing activities and environmental documents begun before the 
effective date. These regulations do not apply to an environmental 
impact statement or supplement if the draft statement was filed before 
the effective date of these regulations. No completed environmental 
documents need be redone by reasons of these regulations. Until these 
regulations are applicable, the Council's guidelines published in the 
Federal Register of August 1, 1973, shall continue to be applicable. In 
cases where these regulations are applicable the guidelines are 
superseded. However, nothing shall prevent an agency from proceeding 
under these regulations at an earlier time.
    (b) NEPA shall continue to be applicable to actions begun before 
January 1, 1970, to the fullest extent possible.
