(d) Customer facilities not designated as a
cross connection hazard by subsection (c) may be designated a cross connection
hazard by written notification from the commissioner to the customer and to the
customer's public water system. The notice shall specify the nature of the
customer activity that necessitates designation of the customer's facility as a
cross connection hazard, and the date by which the customer shall install a
cross connection control device in accordance with section 7 of this rule, on
the customer service line to the facility so designated.
(e) The commissioner may issue a letter
exempting a customer from the requirements of subsection (a) if the customer
can show to the satisfaction of the commissioner that the activities taking
place at the customer's facility, and the materials used in connection with
these activities or stored on the premises, cannot endanger the health of
customers of the public water system should backflow occur. An exemption shall
remain valid for no more than three (3) years from the date of issuance. If the
commissioner finds that the customer facility has become a cross connection
hazard, the commissioner will void the exemption and so notify the customer.
