OPINION
AND
ORDER OF
THE
BOARD
(by Mr. Dumelle):
Only one comment was received on the Board’s Proposed
Opinion and Order dated August
3,
1978.
That comment was sub-
mitted by the Chief of the Environmental Control Division of the
Attorney General’s Office.
He objected to the fact that the
Monsanto Company was mentioned by name in the proposed amendment
to Rule 702 of Chapter
3:
Water Pollution.
The objection is
well taken.
The Board does not intend to adopt specific standards
for specific corporations.
Rather, the Board
is acknowledging
the fact that specific industries have water pollution problems
which are peculiar to their industrial category.
When these
problems are viewed in conjunction with the nature of the
receiving stream
(in this case, the Mississippi River)
a valid
site specific standard can be fashioned.
The language of the
new Rule 702(f)
has been adjusted to reflect this principle.
The Board hereby adopts its Proposed Opinion dated
August
3,
1978 and this Opinion as its Opinion in this pro-
ceeding.
ORDER
It is the Order of the Pollution Control Board that Rule
702 of Chapter
3:
Water Pollution of the Board’s Rules and
Regulations be amended by the addition of a new subsection
(f)
which shall read as follows:
