The operator of a food establishment that has a molluscan shellfish life support system display tank shall ensure that

(1) the safety and quality of the molluscan shellfish as they were received is not compromised by use of the tank;

(2) each system is equipped with

(A) tanks that
(i) have smooth, cleanable surfaces;

(ii) are durable and accessible for washing, rinsing, and sanitizing, as described in 18 AAC 31.422 - 18 AAC 31.424;

(iii) have plumbing and spray nozzles that are cleanable and made from safe materials; and

(iv) hold at least 100 gallons of water per 75 pounds of molluscan shellfish;

(B) plumbing that
(i) will not be a source of contamination;

(ii) does not have pipes or hoses that can fill with stagnant water; and

(iii) has a device backflow to prevent backflow and back-siphonage to protect the potable water supply; and

(C) a recirculation system that includes
(i) filtration to remove particulate matter and ammonia;

(ii) a disinfection system to remove coliform bacteria from the water; if an ultraviolet (UV) light system is used, the ultraviolet lights must be cleaned at least every six weeks and the bulbs must be replaced at least once every 365 days; and

(iii) a refrigeration unit to maintain water at 40 - 60º F;

(3) water used with seafood other than molluscan shellfish does not flow into the molluscan tank;

(8) the tank and recirculation system are washed, rinsed, and sanitized, as specified at 18 AAC 31.422 - 18 AAC 31.424, at least once every seven days;

(9) if a tank and recirculation system is used for a species other than molluscan shellfish, the tank and recirculation system are washed, rinsed, and sanitized, as specified at 18 AAC 31.422 - 18 AAC 31.424, before use for a molluscan shellfish;

(10) defoamers, if used, are of food-grade quality and do not cause the molluscan shellfish to become adulterated; and
