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.</span><span style='font-family:&quot;Arial&quot;,sans-serif'></span></p> <span style='font-size:11.0pt;line-height:107%;font-family:&quot;Arial&quot;,sans-serif; mso-fareast-font-family:Calibri;mso-fareast-theme-font:minor-latin;mso-ansi-language: 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.</span>
