(b) Except as provided in (h) of this section or under AS 46.03.462 (c) - (e), a person may not discharge sewage from a commercial passenger vessel into the marine waters of the state that has suspended solids greater than 150 milligrams per liter or a fecal coliform count greater than 200 colonies per 100 milliliters except that the department may by regulation adopt a protocol for retesting for fecal coliform, if this discharge limit for fecal coliform is exceeded, under which a discharger will be considered to be in compliance with the fecal coliform limit if the geometric mean of fecal coliform count in the samples considered under the protocol does not exceed 200 colonies per 100 milliliters. Upon submission by the owner or operator of a small commercial passenger vessel of a plan for interim protective measures under AS 46.03.462 (c)(2) and (d), the department shall extend the time for compliance of that vessel with this subsection.

(c) Except as provided in (h) of this section or under AS 46.03.462 (c) - (e), a person may not discharge graywater or other wastewater from a commercial passenger vessel into the marine waters of the state that has suspended solids greater than 150 milligrams per liter or a fecal coliform count greater than 200 colonies per 100 milliliters except that the department may by regulation adopt a protocol for retesting for fecal coliform, if this discharge limit for fecal coliform is exceeded, under which a discharger will be considered to be in compliance with the fecal coliform limit if the geometric mean of fecal coliform count in the samples considered under the protocol does not exceed 200 colonies per 100 milliliters. Upon submission by the owner or operator of a large commercial passenger vessel of a plan for interim protective measures, the department shall extend the time for compliance of that vessel with this subsection for a period of time that ends not later than January 1, 2003.

(d) The department may by regulation establish numeric or narrative standards for other parameters for treated sewage, graywater, and other wastewater discharged from commercial passenger vessels. In developing regulations under this subsection, the department shall consider the best available scientific information on the environmental effects of the regulated discharges, the materials and substances handled on the vessels, vessel movement effects, and the availability of new technologies for wastewater.

(e) Except as provided in (g) and (h) of this section or under AS 46.03.462(c) - (e), a person may not discharge any treated sewage, graywater, or other wastewater from a large commercial passenger vessel into the marine waters of the state unless

(1) the vessel is underway and proceeding at a speed of not less than six knots;

(2) the vessel is at least one nautical mile from the nearest shore, except in areas designated by the department;

(3) the discharge complies with all applicable vessel effluent standards established under the federal cruise ship legislation and any other applicable law; the standards under the federal cruise ship legislation and other applicable law may be adopted by regulation by the department; and

(4) the vessel is not in an area where the discharge of treated sewage, graywater, or other wastewater is prohibited.

(f) Except as provided in (h) of this section, a person may not discharge sewage from a small commercial passenger vessel unless the sewage has been processed through a properly operated and properly maintained marine sanitation device.

(g) The provisions of (e)(1) and (e)(2) of this section do not apply to a discharge permitted under sec. 1404(b) or (c) of the federal cruise ship legislation.

(h) The provisions of (a) - (f) of this section do not apply to discharges made for the purpose of securing the safety of the commercial passenger vessel or saving life at sea if all reasonable precautions have been taken for the purpose of preventing or minimizing the discharge.
