(a) Description. Zone 1D is that part of the Delaware River exending from Tocks Island Dam, RM 217.0 (proposed axis of dam), to the mouth of the Lehigh River at Easton, PA, RM 183.66.
(b) Water uses to be protected. The quality of zone 1D waters shall be maintained in a safe and satisfactory condition for the following uses:
1. (i) public water supplies after reasonable treatment;
2. (ii) industrial water supplies after reasonable treatment;
3. (iii) agricultural water supplies;
  (2)
4. (i) maintenance and propagation of resident game fish and other aquatic life;
5. (ii) spawning and nursery habitat for anadromous fish;
6. (iii) passage of anadromous fish;
7. (iv) wildlife; and
8. (3) recreation.
  (c) Stream quality objectives.
9. (1) Dissolved oxygen:
  1. (i) not less than 4.0 mg/l at any time;
  2. (ii) minimum 24-hour average of 5.0 mg/l.
10. (2) Temperature. Except in designated heat dissipation areas (see section 861.12[f][2]) of this Title):
  1. (i) not to exceed 5°F (2.8°C) rise above ambient temperature until stream temperature reaches 87°F (30.6°C); and
  2. (ii) natural temperature will prevail above 87°F (30.6°C).
11. (3) pH. Between 6.5 and 8.5 inclusive, unless outside this range due to natural conditions.
12. (4) Phenols. Not to exceed 0.005 mg/l, unless due to natural conditions.
13. (5) Threshold odor number. Not to exceed 24 at 60°C.
14. (6) Synthetic detergents (M.B.A.S.). Not to exceed 0.5 mg/l.
15. (7) Radioactivity:
  1. (i) alpha emitters, not to exceed 3 pc/l (picocuries per liter);
  2. (ii) beta emitters, not to exceed 1,000 pc/l.
16. (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.
17. (9) Total dissolved solids. Not to exceed:
  1. (i) 133 percent of background; or
  2. (ii) 500 mg/l, whichever is less.
18. (10) Turbidity. Unless exceeded due to natural conditions:
  1. (i) maximum 30-day average 20 units;
  2. (ii) maximum 150 units.
    (d) Effluent quality requirements.
19. (1) All discharges shall meet the effluent quality requirements of this Part.
20. (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.
