I. Maintain a current map/site plan showing sources and structural BMP locations. (Use Exhibit C map as a <br /> base map.) <br /> EXISTING DISCHARGES: Due to the vegetation, terrain, and surficial geology and soils, there are no existing <br /> discharges from the operations area. IF THERE WERE A DISCHARGE, it would be to the East-Southeast to Dutton <br /> Creek, a tributary of the Piedra River. There is some minor potential (based on bar ditches along streets) for some <br /> discharge to enter Stevens Reservoir,which lies along Dutton Creek, which in turn flows into Martinez Creek. <br /> MONITORING AND SAMPLING REQUIREMENTS: None. No discharge to surface waters of the State. <br /> RECORDING AND REPORTING REQUIREMENT: Report of monthly, quarterly, and annual inspections of BMP and <br /> water on-site-, Report quarterly of No Discharge(using DMR form on-line), Report annually of compliance with report. <br /> THIS SURFACE WATER MANAGEMENT PLAN PREPARED BY Nathan A.
