Current through Register Vol. 46, No. 39, September 25, 2024

(a) Description. Zone W2 is:

(1) Sand Pond Creek, extending from RM 1.8 at the confluence of Sherman Creek and Starboard Creek in Pennsylvania to its mouth in New York at RM 10.1 on the West Branch Delaware River;

(2) Cat Hollow Brook, extending from its source in New York to its mouth in Pennsylvania at RM 1.05 on Sand Pond Creek;

(3) Sherman Creek in Pennsylvania, extending from its source to its mouth at RM 1.8 on Sand Pond Creek.

(4) An unnamed tributary of Sherman Creek, extending from its source in New York to its mouth in Pennsylvania at RM 1.6 on Sherman Creek; and

(5) Starboard Creek, extending from its source in Lake Oquaga in New York to its mouth in Pennsylvania at RM 1.81 on Sand Pond Creek.

(b) Water uses to be protected. The quality of zone W2 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° F (1.1° C) rise above ambient temperature when stream temperature is between 50° F (10.0° C) and 58° F (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.

(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.
