(4) Before a two-compartment sink is used:

(a) The permit holder shall have its use approved; and

(b) The permit holder shall limit the number of kitchenware items cleaned and sanitized in the two-compartment sink, and shall limit warewashing to batch operations for cleaning kitchenware such as between cutting one type of raw meat and another or cleanup at the end of a shift, and shall:

(i) Make up the cleaning and sanitizing solutions immediately before use and drain them immediately after use; and

(ii) Use approved procedures to properly clean and sanitize kitchenware.

(5) A two-compartment sink may not be used for warewashing operations where cleaning and sanitizing solutions are used for a continuous or intermittent flow of kitchenware or tableware in an ongoing warewashing process.
