(ii) maintenance and propagation of shellfish;
(iii) passage of anadromous fish;
(iv) wildlife;
(3) recreation; and
(4) navigation.
(c) Stream quality objectives.
(1) Dissolved oxygen:
(i) 24-hour average concentration shall not be less than 6.0 mg/l; and
(ii) not less than 5.0 mg/l at any time unless due to natural conditions.
(2) Temperature.
(i) Shall not be raised above ambient by more than:
(a) 4°F (2.2°C) during September through May; nor
(b) 1.5°F (0.8°C) during June through August;
(ii) Nor shall maximum temperatures exceed 85°F (29.4°C). (See section 861.12[f][4] of this Title.)
(3) pH.
Between 6.5 and 8.5 inclusive, unless outside this range due to natural conditions.
(4) Phenols.
Maximum 0.01 mg/l, unless exceeded due to natural conditions.
(5) Threshold odor number.
Not to exceed 24 at 60°C.
(6) Synthetic detergents (M.B.A.S.).
Maximum 30-day average 1.0 mg/l.
(7) Radioactivity:
(i) alpha emitters, maximum 3 pc/l (picocuries per liter); and
(ii) beta emitters, maximum 1,000 pc/l.
(8) Bacteria.
(i) Fecal coliform. Maximum geometric average 200 per 100 milliliters.
(ii) Enterococcus. Maximum geometric average 35 per 100 milliliters.
(iii) Coliform. MPN (most probable number) not to exceed Federal shellfish standards in designated shellfish areas.
(9) Turbidity.
Unless exceeded due to natural conditions:
(i) maximum 30-day average 40 units; and
(ii) maximum 150 units.
(10) Alkalinity.
Between 20 and 120 mg/l.
(11) Toxic pollutants.
(i) Applicable criteria to protect the taste and odor of ingested water and fish are presented in Table 4.
(ii) Applicable marine stream quality objectives for the protection of aquatic life are presented in Table 5.
(iii) Applicable marine stream quality objectives for the protection of human health are presented in Tables 6 and 7.
(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.
Note:
The application of sections 860.22(c)(8), 862.28(c)(8) and 860.29(c)(8) of this Part to all existing dischargers in Zones 2, 3 and 4 is temporarily suspended from October 1, 1987 to April 30, 1988, unless reinstated earlier in whole or in part by order of the executive director.
