Sacramento County Stormwater Quality Program

1. Overview of the Sacramento County Stormwater Quality Program Presentation to Sacramento Environmental Commission May 21, 2018

2. Regulatory Background • The Federal Clean Water Act (CWA) establishes the structure for regulating discharges of pollutants into waters of the United States • Per the CWA, entities that own and operate storm drain systems are required to have a National Pollutant Discharge Elimination System (NPDES) permit and implement a program that reduces the discharge of pollutants

3. NPDES Permit – Sacramento County • First permit issued in 1990. All other incorporate cities within County also have a NPDES permit (except Isleton) • County and cities have formed a partnership to achieve efficiency for shared NPDES permit requirements • This partnership is known as the Sacramento Stormwater Quality Partnership and includes Sacramento County and the cities within the Sacramento County boundary • Beginning in 2016, permits are now region-based and permit requirements have evolved from being activity focused to outcome focused

4.

5. General Stormwater Permit Requirements • Effectively prohibit non-stormwater discharges • Monitor discharge and receiving water quality • Reduce pollutants in stormwater to the maximum extent practicable (MEP) • Develop and implement a Stormwater Quality Improvement Plan (SQIP) to accomplish these objectives • Submit Annual Reports

6. County Stormwater Regulations • Stormwater Ordinance • County Code Chapter 15.12 • Land Grading and Erosion Control Ordinance • Erosion and Sediment Control Standards and Specifications • New Development Standards

7. Elements of the County’s Stormwater Quality Program • Public Education and Outreach* • Monitoring* • Water Quality Based Program (Target Pollutant Program)* • Program Management • Construction • Commercial/Industrial* • Municipal Operations • Illicit (Illegal) Discharges • Planning and New Development * Indicates joint program activities performed collectively as the Sacramento Stormwater Quality Partnership

8. Construction Element • Examples of compliance activities: • Conduct plan review and permitting starting at the earliest possible stage of a project • Inspect construction sites and enforce ordinances and codes to control construction-related discharges • Provide improvement standards and specifications to the construction community

9. Commercial/Industrial Element Examples of compliance activities: • Inspections of 9 business categories conducted through EMD’s Commercial and Industrial Stormwater Compliance Program (over 5,000) • Develop compliance assistance materials • Enforcement of local Stormwater Ordinance

10. Illicit Discharges Element Examples of compliance activities: • Public complaint response and enforcement of the Stormwater Ordinance for: • Prohibited non-stormwater discharges • Illicit connections

11. Municipal Operations Element Examples of compliance activities: • Conduct annual training for employees • Conduct inspections of County facilities to ensure compliance • Develop pollution prevention plans for municipal sites and activities

12. Monitoring and Target Pollutant Element Examples of compliance activities: • Conduct monitoring to characterize urban runoff and receiving water quality • Identify and focus resources on pollutants most likely to impair local receiving waters • Develop pollution control strategies and best management practices to address target pollutants

13. Public Education and Outreach Element Examples of compliance activities: • Develop educational materials, conduct media campaigns, and encourage public participation in creek cleanups and pollution prevention practices • Target groups include businesses, school children, and community residents

14. New Development Element Examples of compliance activities: • Ensure compliance with New Development Standards that require post-construction stormwater treatment measures • Conduct outreach to educate the development community about requirements

15. Next Steps in Stormwater Low Impact Development (LID) • Reduce impervious surfaces through the use of alternative materials or alternative site layouts • Preserve or create vegetated areas • Divert flows from impervious surfaces away from drains and into vegetation • Uses vegetation to reduce pollutants

16. LID – Plan Review

17. Next Steps in Stormwater (continued) Trash Policy By 2030, all permittees must capture all trash 5mm or greater from Industrial, Commercial and Residential (>10du/ac) properties either by: • Track 1 - installing of Full Capture Trash Systems or • Track 2 - combination of activities

20. Next Steps in Stormwater (continued) Monitoring and Program Management • Priority Water Quality Constituents • water quality outcome based reporting • Regional Monitoring • Constituents of Emerging Concern
