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

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

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 The first Stormwater Permit was issued to the Permittees in 1990 Permits are renewed in 5 years terms and we’re currently in the process of negotiating the terms of our fourth permit

County Departments Involved in Permit Compliance Water Resources (Administers Permit) Community Planning and Development Construction Management and Inspection Division Transportation Regional Parks Environment Management Department District Attorney Sheriff Department of General Services Sacramento County Airport System Department of Waste Management and Recycling DWR is the lead group in implementing the County’s Stormwater Permit: we’re a resource to other depts. we provide training we coordinate with other depts. to collect and compile data documenting permit compliance we prepare permit compliance reports and other required submittals

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 The SQIP is available on our website, the link to which is provided on the last slide

Elements of the County’s Stormwater Quality Program Construction Commercial/Industrial* Municipal Operations Illicit (Illegal) Discharges Planning and New Development Public Education and Outreach* Monitoring* Water Quality Based Program (Target Pollutant Program)* Program Management Joint Program activities: are cost effective provide area-wide consistency, which makes it easier for businesses to comply Stormwater regulations * Indicates joint program activities performed collectively as the Sacramento Stormwater Quality Partnership

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

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

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

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

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

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

New Development Element Examples of stormwater treatment measures include: vegetated swales detention basins sand filters bioretention: Using the chemical, biological and physical properties of plants, microbes and soils for removal of pollutants from storm water runoff 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

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

LID – Plan Review

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

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