Article 7: Alternative System Requirements
(a) Alternative system may be permitted by DEH for the repair or upgrading of any existing system and for new construction on any legally created lot where it is determined that wastewater cannot be disposed of in a sanitary manner by a standard system.
(b) Types of alternative systems permitted shall be limited to those identified in Manual, except as provided in paragraph (d).
(c) All supplemental systems shall be installed by a contractor. Where the installation includes a proprietary treatment system certified and listed by National Sanitation Foundation, the contractor shall also possess any required manufacturer certifications, as applicable.
(d) Systems that are not included as a system type in the Manual, but that are proposed or installed as part of an active accredited university research project or field trial may be allowed with approval from DEH provided the system monitoring is performed by the university and the system(s) meet the minimum requirements of the OWTS Policy. Such system installation may require special contracts or memoranda of understanding to clarify requirements, to communicate what happens with the system at the end of the study or trial period, and requirements if the system fails.
(Ord. 1469, eff. July 14, 2016)
(a) General requirements for site evaluation and for obtaining an installation permit are prescribed in Article 6 of this chapter and in the Manual.
(b) An alternative system design shall be prepared and signed or stamped by a qualified system designer. The qualified system designer shall also be responsible for inspections of the system installation to assure conformation with approved plans.
(c) System design will be reviewed by DEH and, where warranted, such as due to the complexity of the system, DEH may refer the plans to the California Central Valley Regional Water Quality Control Board staff and/or external third-party expert consultant(s) for additional review, the costs for which would be the responsibility of the applicant.
(Ord. 1469, eff. July 14, 2016)
(a) An OM&M program will be established by DEH to encourage or require inspection, monitoring, and/or service to systems, including standard and alternative systems, as delineated in the Manual to insure long-term performance, and groundwater and public health protections. The OM&M program will be in accordance with guidelines in the Manual and may also incorporate specific recommendations of DEH, system consultant/designer, manufacturer, and/or qualified professional.
(b) Monitoring of alternative systems shall be conducted by or under the supervision of a qualified service provider unless otherwise provided in the Manual.
(c) The Director of Environmental Health may require third-party or County monitoring of any supplemental system where deemed necessary because of special circumstances, such as the complexity of the system or the sensitive nature of the site. The costs for such additional monitoring are the responsibility of the owner.
(d) Monitoring results shall be submitted to DEH in accordance with reporting guidelines provided in the Manual. DEH shall be notified immediately of any system problems observed during the system inspection and monitoring that could lead to the system failure.
(e) In addition to regular inspection and monitoring activities, the Director of Environmental Health may require inspections after significant events such as flood, seismic event and localized fire, etc. The Director of Environmental Health will be responsible for issuing appropriate notices when such inspections are required; those conducting the inspections shall report the inspection results to the Director of Environmental Health. The purpose of such inspections will be to assess and document any damage to the system and to implement corrective actions, as needed, in a timely manner.
