Description: <span style='font-family:"Arial",sans-serif;
color:black;mso-color-alt:windowtext'>An Advanced Protection Management Program
(APMP) is a management program that establishes standards for Onsite Wastewater
Treatment Systems (OWTS) near impaired waterbodies.
<span style='font-family:"Arial",sans-serif;
color:black;mso-color-alt:windowtext'>The Action Plan for the Russian River
Pathogen TMDL establishes minimum requirements for all OWTS within the
designated APMP area for the Russian River Watershed. Owners of existing, new
and replacement OWTS whose OTWS are located entirely outside the boundaries of
the APMP are not subject to the APMP requirements, but must still comply with
relevant requirements of the OWTS Policy and any approved Local Agency
Management Program (LAMP), and if applicable, individual/general waste
discharge requirements or waiver of waste discharge requirements.

EN-US;mso-fareast-language:EN-US;mso-bidi-language:AR-SA'>The Action Plan
establishes a 600-foot zone of influence for OWTS adjacent to perennial
streams, which for the purposes of the Action Plan are blueline streams that
are depicted on the USGS 1:100,00 scale topographic map, and a 200-foot zone of
influence for lower class streams that are derived using a LIDAR dataset. The
600-foot distance is based on a microbial contamination zone that was
recommended by the California Department of Public Heath (CDPH, 1999) to
protect water supply from viral, microbial and direct chemical contamination.
