Sec. 306. (a)  No Federal  agency may enter  into any  contract
with any person who is convicted of any offense under section 113
(c)  for the  procurement of  goods, materials,  and services  to
perform  such  contract at  any facility  at which  the violation
which gave rise to  such conviction occurred if such  facility is
owned, leased, or  supervised by such person. The  prohibition in
the preceding  sentence  shall continue  until the  Administrator
certifies that the condition giving rise to such a conviction has
been corrected. For convictions arising under section  113(c)(2),
the  condition  giving  rise  to  the  conviction  also  shall be
considered  to  include any  substantive  violation  of this  Act
associated with the violation of 113(c)(2). The Administrator may
extend this prohibition to other facilities  owned or operated by
the convicted person
  (b) The Administrator shall establish procedures to provide all
Federal agencies with the notification necessary for the purposes
of subsection (a).
  (c) In order to  implement the purposes and policy  of this Act
to  protect  and enhance  the quality  of  the Nation's  air, the
President  shall, not more than  180 days after  enactment of the
Clean Air Amendments  of 1970  cause to  be issued  an order  (1)
requiring each Federal agency  authorized to enter into contracts
and  each Federal  agency  which is  empowered to  extend Federal
assistance by way of  grant, loan, or contract to  effectuate the
purpose  and policy of this Act in such contracting or assistance
activities,   and  (2)   setting  forth   procedures,  sanctions,
penalties, and such other provisions, as the President determines
necessary to carry out such requirement.
  (d)  The President may exempt any contract, loan, or grant from
all or part of the provisions of this section where he determines
such  exemption  is necessary  in the  paramount interest  of the
United States and he shall notify the Congress of such exemption.
  (e)  The President  shall annually  report  to the  Congress on
measures taken toward implementing the purpose and intent of this
section, including but  not limited to the  progress and problems
associated with implementation of this section.
