Ordinance No. 2296 Page 9 of 12 i. An exception may be granted for an alternate method of premises containment if the customer can definitively provide documentation certified by a cross -connection control specialist, that there is no alternative option available for the installation of the type of BPA required under the CCCPH and the alternative method of backflow protection provides at least the same level of protection as the CCCPH required BPA, and there is no potential hazard possible from the premises protected with the alternative method; which upon review is approved by the public works director or designee, Fire Marshall, city cross -connection control specialist, and if not permitted under the CCCPH, approval by State Water Board staff is required. Such an exemption can be revoked at anytime an actual or potential hazard is suspected or until time of any change to either the status of no alternative or degree of hazard changes. D. The type of BPA required under subsections (C)(1), (2), (3), (4) and (5) of this section shall depend upon the degree of hazard which exists in accordance with City Standards, State Water Resources Control Board, Cross -Connection Control Policy Handbook Appendix C, and as follows: 1. In the case of any premises where there is an auxiliary water supply as stated in subsection (C)(1) of this section and it is not subject to any of the following rules, the public water system shall be protected by an approved airgap separation or an approved RP. 2. In the case of any premises where there is water or substance that would be objectionable but not hazardous to health; if introduced into the public water system, the public water system shall be protected with no less than an approved RP assembly. 3. In the case of any premises where there is any material dangerous to health which is handled in such a fashion as to create an actual or potential hazard to the public water system, the public water system shall be protected by an approved air - gap separation or an approved reduced pressure principle backflow prevention assembly. Examples of premises where these conditions will exist include chemical manufacturing plants, hospitals, mortuaries and plating plants. 4. In the case of any premises where there are cross -connections, either actual or potential, the public water system shall be protected by an approved AG or an approved RP at the service connection. 5. In the case of any premises where, because of security requirements or other prohibitions or restrictions it is impossible or impractical to make a complete in -plant cross -connection survey, the public water system shall be protected against backflow or back -siphonage from the premises by the installation of a BPA in the service line. In this case, maximum protection will be required; that is, an approved AG or an approved reduced pressure principle backflow prevention assembly shall be installed in each service to the premises.
