2. The public water system or owner is unable to comply with the regulation due to compelling factors, not including economic factors.

D. An exemption shall not alter the degree of hazard classification of the cross-connection and shall not exclude the use of some appropriate anti-backflow device not necessarily assigned to the particular degree of hazard assigned to the cross-connection. Prior to granting an exemption, the Commissioner shall provide notice in a local newspaper and give an opportunity for public hearing on the proposed exemption. Each exemption may also be conditioned on monitoring, testing, analyzing or other requirements to ensure the protection of public health, and shall include a compliance schedule.
