  3. Goals and Objectives • Identify and Implement adequate BMPs to reduce source of pollutants during municipal maintenance activities • Keep records and report measurable results annually

  4. Sediments Nutrients Pathogens Oil and grease Metals Organic Chemicals Pesticides Trash/Litter Vector production BOD/COD pH Others Pollutants Associated with Municipal Activities

  5. Public Street and Road Sweeping and Cleaning Street/Road Repair & Maintenance Sidewalk/Plaza Maintenance Bridge & Structure Maintenance Landscape Maintenance Litter/Trash Control Catch Basin Inspection and Cleaning Stormwater Pump Station and ConveyanceSystems Rural Public Works Maintenance and Support Corporate Yard Maintenance Lagoon Maintenance Component Activities

  6. Contribution Credit • Plain Black Type are Work Group’s product • Redlines/Strikeouts and/or Red Colored Type are Water Board Staff’s comments

  7. Current Regulatory Status • Municipal maintenance has been one of the core program components • Programs develop their own Performance Standards under the current permits • Existing permits lack specific uniform Performance Standards to measure compliance

  8. Major Expectations • Identify effective Performance Standards • More clearly specify implementation levels • Measure pollutant source removal, inspection, and cleanup efforts by record keeping and reporting annually

  9. Street Sweeping Implementation • Assign street sweeping priorities as: • High Priority • Medium Priority • Low Priority • Street sweeping frequencies: • High Priority – average twice/month • Medium Priority – average once/month • Low Priority – twice/year before onset of rainy season • Where street sweeping is not technically feasible, Permittees are required to • Increase trash/litter removal and control efforts • Conduct seasonal efforts to remove leave from paved surfaces

  10. Trash and Litter Control • Identify and assess potential litter/trash accumulation areas • Identify potential management actions to reduce trash levels at identified areas • Provide public trash receptacles in trash prone areas, most probably in high priority sweeping locations • Retrofit storm drain inlets in high traffic areas and pump stations • Cover grates and swirl separators • Improve public outreach

  11. Pump Stations • Address water quality problems • Inventory existing pump stations • Control and remove trash • Implement monitoring of flows, DO, conductivity, other pollutants • Explore diversion to sanitary sewer (dry weather flows and first flush)

  12. Comments Received from NGO • Street Sweeping • Cost-benefit analysis • Training expectations • Operation and Maintenance of Channels • Permit Activities • Monitor pump-station discharges • Inspect, maintain, and design or re-design outfalls to minimize erosion and sedimentation • Tidal Lagoon

  13. Comments Receivedfrom NGO • Litter/Trash Clean Up • Report problem site on a GIS-based system • Require specific increased trash removal (e.g. 10% of problem areas and three sites per permit) • Catch Basin Inspection and Cleaning • Report locations on a GIS system • Increase cleaning frequency
