OPINION

AND ORDER OF THE BOARD

(by Mr. Goodman):

The Board hereby adopts as its Proposed Final Draft in this

matter, and orders publication of,

the regulatory amendments set

forth below.

A’public comment period will be allowed for 45 days

from the date of this Order.

The Board’s Proposed Final Draft differs from the Proponents’

Amended Proposal, published in Environmental Register #138

(December 14,

1976),

in that it substitutes the term “Freon Extrac-

table Material” for the term “Hexane Extractable Material,” and

substitutes “monthly period”

for “consecutive 30-day period.”

PROPOSED FINAL DRAFT

In Rule 408(a)

of Chapter

3: Water Pollution, delete “Oil

(hexane solubles or equivalent),

and

add

“Oil

(freon

solubles

or

equivalent)” as follows:

“Constituent

Storet Number

Concentration

(mg/i)

Oil

(Freon

00550,

00556

15.00**

Solubles or equivalent)

00560

**Ojl may be analytically separated into polar and non-

polar components.

If such separation

is done, neither

of the components

may

exceed 15 mg/i

(i.e.,

15 mg/i polar

freon extractable materials and 15 mg/i non-polar freon

extractable materials).

Com~iiancewith this numerical

standard shall be determined on the basis of 24 hour com-

posite samples, averaged over any monthly period; provided,

however,

that no single ~24 hour composite shall be greater

than

2 times the numerical standard and no grab sample

shall be greater than

5 times the numerical standard.”

IT IS SO ORDERED.
