AUTHORITY AND REFERENCES <br /> <br />The authority for the monitoring and sampling of sanitary sewer overflows are contained in the following <br />regulations: <br /> <br />1. State Water Resources Control Board Waste Discharge Requirements Order No. 2006-0003- <br />DWQ, Section D.7(v). <br />2. State Water Resources Control Board Monitoring and Reporting Program (MRP) Sections C.5 D, <br />Executive Order number WQ 2013-0058-EXEC effective September 9, 2013 <br />3.

IDENTIFICATION OF LOCAL SURFACE WATERS AND CHARACTERISTICS <br /> <br />An important element of any water quality monitoring program is the proper and thorough understanding <br />of the service area and the various challenges the geography and sanitary sewer infrastructure of the <br />service area present for the potential of wastewater reaching surface waters or storm water facilities. By <br />evaluating the areas of concern in a service area such as lakes, rivers, dry creeks, aerial pipeline <br />crossings over water ways and all storm water related infrastructure, the City can be better prepared to <br />timely respond to any SSO reaching surface waters and to minimize the impacts of an SSO in or around <br />local surface waters and storm water infrastructure. <br /> <br />A. Background Monitoring <br /> <br />Background monitoring of surface waters in the City’s service area is intended to provide a profile <br />of the water quality with respects to the constituents measured twice each year. This background <br />data will serve as a reference point for determining the level, if any, of water quality impairment <br />following an SSO impacting surface waters in the service area. <br /> <br />1. The City of Redwood City will perform background monitoring of the following surface <br />waters: <br /> Redwood Creek <br /> Jefferson Branch <br />6.2.A. - Page 173
