City of Redwood City, Public Works Division Initial Study & Mitigated Negative Declaration <br />Document Date: October 15, 2015 <br />Revision Date: January 25, 2016 Page 58 Blankinship & Associates, Inc. <br /> <br />4.0 MITIGATION MEASURES <br />4.1 Hydrology & Water Quality <br /> <br />HWQ-1. As required by the SIP and the SWRCB general permit for the application of aquatic <br />herbicides, the City or contractor will revise its Aquatic Pesticide Application Plan <br />(APAP) to reflect the use, monitoring and reporting of copper-containing aquatic <br />herbicides upon being listed on the SIP Exception list of the permit. The APAP will <br />call for surface water sampling and analysis before, during, and after Project <br />completion to assess the impact, if any, that the Project may have on beneficial uses <br />of water. Additionally, consistent with SIP exception requirements, the City or <br />contractor will arrange for a qualified biologist to assess impacts to receiving water <br />beneficial uses. <br /> <br />4.2 Mitigation Monitoring and Reporting Program <br /> <br />Mitigation HWQ-1 is the implementation of the City’s Aquatic Pesticide Application Plan <br />(APAP) that requires surface water sampling, analysis, visual monitoring, and reporting as a <br />condition of the NPDES Aquatic Permit issuance. The City’s APAP has been reviewed and <br />approved by the SWRCB and reporting to them is done annually by March 1. Implementation <br />of the APAP mitigates any significant environmental effects of aquatic herbicide use. <br /> <br /> <br />6.3.A. - Page 66
