Section 8:13-2.12 - Seawater quality

(a) No seawater shall be used for depuration unless it meets the following requirements:

1. The source seawater meets or is better than the criteria for Special Restricted Waters as specified in the Model Ordinance then in effect.

2. The source seawater shall be free of toxic chemicals, pesticides, detergents, dye stuffs, radioisotopes and marine toxins in concentrations which exceed established State/Federal rules or regulations, or exist in concentrations deemed hazardous by State or Federal officials.

3. Salinity must be within 20 percent of the harvest area value, at the time of harvest.

(b) The seawater in which the undepurated clams are placed for depuration shall be of sufficient quality to assure optimal physiological activity. The following requirements shall be met either naturally or through treatment of the water:

1. No detectable organisms of the coliform group in the tank influent as measured by a recognized multi-tube MPN per 100 milliliter test for potable water or a test of equivalent sensitivity;

2. The pH shall be between the range of 7.0 to 8.4;

3. The dissolved oxygen levels shall be a minimum of 5.0 mg/liter;

4. Turbidity shall not be more than 20 Nephelometric turbidity units; and

5. Temperature range shall be a minimum of 35 degrees Fahrenheit (2.0 degrees Celsius) to a maximum of 68 degrees Fahrenheit (20 degrees Celsius) for soft shell clams; and a minimum of 50 degrees Fahrenheit (10 degrees Celsius) to a maximum of 68 degrees Fahrenheit (20 degrees Celsius) for hard shell clams unless different maximum and minimum temperature values are documented that provide effective depuration during the scheduled depuration process verification study.

i. Refrigeration units shall be installed of sufficient capacity to cool and maintain processing water 68 degrees Fahrenheit (20 degrees Celsius) or below.

ii. A system shall be established to raise and maintain the water temperature above 35 degrees Fahrenheit (2.0 degrees Celsius) for soft shell clams and 50 degrees Fahrenheit (10 degrees Celsius) for hard shell clams.
