 The Board~sfunction is like that of
 a court; we canno~
investigate or prove cases
 but must decide on the basis of
evidence presented by the parties.
 This is often
 a difficult
task, but the
 burden
 has been successfully borne a number of
times in the Board~sbrief history.
 E.g., League of Women
Voters v.
 North
 Shore Sanitary District, #7O~7
(March
 31, 1971).
For complainants
 who
 are
 not prepared to assume such an active
part,
 we can
 treat the
 complaint as an informal one and
 refer
it to the Environmental Protection Agency,
 the official state
enforcement agency,
 for investigation and possible prosecution.
We shall allow
 30 days for the filing of an amended formal
complaint,
 in the absence of which we shall refer the matter to
the Agency for investigation.
It is so ordered.
I, Christan Moffett, Clerk of the Pollution Control Board, certify
that the Board adopted the above Preliminary Opinion
