(a) Description. Zone C5 is:
(1) That part of Red Clay Creek
extending from the confluence of the East and West branches of Red Clay Creek
in Pennsylvania at RM 13.4 to RM 12.6, at the Pennsylvania-Delaware state line;
and
(2) West Branch Red Clay Creek
extending from its source to its mouth on Red Clay Creek at RM 13.4.
(b) Water uses to be protected. The quality of zone C5 waters shall be maintained in a safe and satisfactory condition for the following uses:
(1)
(i) public water supplies after reasonable
treatment;
(ii) industrial water
supplies after reasonable treatment;
(iii) agricultural water supplies;
(2)
(i) maintenance and propagation of resident
game fish and other aquatic life;
(ii) maintenance and propagation of
trout;
(iii) wildlife;
and
(3)
recreation.
(c) Stream quality objectives.
(1) Dissolved oxygen:
(i) not less than 5.0 mg/l at any
time;
(ii) minimum 24-hour average
of 6.0 mg/l; and
(iii) not less
than 7.0 mg/l in spawning areas whenever temperatures are suitable for trout
spawning.
(2)
Temperature. Except in designated heat dissipation areas (see section
861.12[f][5] of
this Title):
(i) not to exceed 5° F (2.8° C)
rise above ambient temperature until stream temperature reaches 50° F (10.0°
C);
(ii) not to exceed 2° (1.1° C)
rise above ambient temperature when stream temperature is between 50° F (10.0°
C) and 58° (14.4° C); and
(iii)
natural temperature will prevail above 58° F (14.4° C).
(3) pH. Between 6.0 and 8.5.
(4) Phenols. Not to exceed 0.005 mg/l, unless
due to natural conditions.
(5)
Threshold odor number. Not to exceed 24 at 60° C.
(6) Synthetic detergents (M.B.A.S.). Not to
exceed 0.5 mg/l.
(7) Radioactivity:
(i) alpha emitters, not to exceed 3 pc/l
(picocuries per liter); and
(ii)
beta emitters, not to exceed 1,000 pc/l
(8) Fecal coliform. Not to exceed 200 per 100
milliliters as a geometric average; samples shall be taken at such frequency
and location as to permit valid interpretation.
(9) Total dissolved solids. Not to exceed:
(i) 133 percent of background; or
(ii) 500 mg/l, whichever is less.
(10) Turbidity.
(i) Not to exceed
(a) the natural background by 10 units;
or
(b) a maximum of 25 units,
whichever is less.
(ii)
Increases not to be attributable to industrial waste discharges.
(d) Effluent quality requirements.
(1) All discharges shall meet
the effluent quality requirements of this Part.
(2) The carbonaceous oxygen demand from an
outfall (exclusive of storm water bypass) shall not exceed that assigned by the
commission to maintain stream quality objectives.
