Sec. 128. (a) Not later  than the date one year after  the date
of the enactment of  this section, each applicable implementation
plan shall contain requirements that - 
     (1)  any board or body which approves permits or enforcement
  orders under this  Act shall have at  least a majority of  mem-
  bers  who represent the public  interest and do  not derive any
  significant  portion of  their income  from persons  subject to
  permits or enforcement orders under this Act, and
     (2) any potential conflicts  of interest by members of  such
  board or body  or the head of an executive  agency with similar
  powers be adequately disclosed.
A State  may adopt any  requirements respecting conflicts  of in-
terest  for such boards or bodies or heads of executive agencies,
or  any other entities which are more stringent than the require-
ments  of paragraphs  (1) and  (2), and  the Administrator  shall
approve any such more stringent requirements submitted as part of
an implementation plan.
