CBRP TIER 1 SOURCE EVALUATION: OVERVIEW

CBRP – Three Step Process • Prioritized drainage areas for evaluation of mitigation alternatives

Step 1

• Selection of non-structural and/or structural BMPs to mitigate source • Completion of Project Identification phase (CIP process) for structural BMP

• Completion of UAAs to facilitate structural BMP projects

Step 2

Step 3

• Completion of Budget/Planning, Design, and Permitting phases of CIP process

• Construction of structural BMPs

CBRP for Middle Santa Ana River Bacterial TMDL Watershed Wide Compliance & Tier 1 Prioritization Analysis

January 15, 2013 Presentation to MSAR Bacteria TMDL Task Force

CBRP Implementation – Step 1 Implement non-structural BMP activities; conduct Tier 1 source evaluation activities to identify controllable urban sources of dry weather flow/bacterial indicators from MS4 outfalls

Evaluate Tier 1 data to identify potential for MS4 outfalls to cause impairment at watershed-wide compliance sites

Impairment not caused by MS4 –Addressed outside of CBRP

Impairment potentially caused by MS4 - Prioritize identified controllable urban sources based on flow volume and/or estimated bacteria load

Key Outcome - Prioritized Drainage Area (PDA)s: PDA #1, PDA #2, PDA #3, etc. CBRP for Middle Santa Ana River Bacterial TMDL Watershed Wide Compliance & Tier 1 Prioritization Analysis

CBRP TIER 1 SOURCE EVALUATION: PRIORITIZATION

Prioritization of MS4 Drainages  Criteria for prioritization – E. coli geomean (mpn/100mL) – Dry weather flow (cfs) – Human Bacteroides (Presence/Absence [P/A]) – Risk of exposure via recreation (High/Low)  Relative rank for each criteria computed  Weighting of criteria to develop a composite score –

Preliminary approach (30 percent each for E.coli geomean, human P/A, and flowrate; 10 percent for risk of exposure)

CBRP for Middle Santa Ana River Bacterial TMDL Watershed Wide Compliance & Tier 1 Prioritization Analysis

January 15, 2013 Presentation to MSAR Bacteria TMDL Task Force

Risk of Exposure Determination  Low – completely concrete lined MS4 system that outfalls to a concrete lined receiving waterbody segment

CBRP for Middle Santa Ana River Bacterial TMDL Watershed Wide Compliance & Tier 1 Prioritization Analysis

January 15, 2013 Presentation to MSAR Bacteria TMDL Task Force

Risk of Exposure Determination 

High – natural channel is present anywhere within an MS4 system, or an outfall that discharges to a natural channel segment of a receiving waterbody

Santa Ana Region-Riverside County MSAR TMDL TF CBRP Implementation Update January 15, 2013

1

Todays Update • Update on CBRP Element 2 Specific BMPs • Update on CBRP Element 3 Inspection Criteria

Element 2: BMPs Transient Camps Ongoing MS4 inspections for transient encampments continue: • Transient camps within MS4 are removed via cooperative program with police, social services, environmental health. • For example on August 13, 2012, University Wash around Spruce Street Bridge.

3

Element 2: BMPs Transient Camps Santa Ana River Clean Up: • Santa Ana River Between County Line to Mission Street Bridge. • Approximately 2 tons of trash and debris cleared out of the river bottom.

4

Element 3: Inspection Criteria Tier 1 Site • Tier 1 Site Monitoring – Bacteroides results showed consistent strong human signal at the Eastvale MDP Line E outlet. – Field visit on December 4, 2012 to asses possible locations to investigate. – Inventory tools for dry weather source assessment.

Questions? Thank You

Element 1: Ordinances Water Conservation and Irrigation Control Permittees have reviewed their existing ordinances to see if they provide sufficient authority to regulate and enforce on sources of dry weather flow. • Existing ordinances, including recently adopted ordinances to comply with AB 1881 and SB7, do provide sufficient authority to regulate and enforce on sources of dry weather flow. Permittees will continue to focus on enforcement of these ordinances. Permittees will continue to collaborate with utility provider • to meet goals of their adopted Urban Water Management Plan (UWMP) where needed. 7

Element 1: Ordinances Pathogen Control Permittees have reviewed their existing Stormwater/Urban Runoff Management and Discharge Control Ordinances to see if they provide sufficient authority to manage animal waste on public and private properties and assign penalties for failure • Existing ordinances do provide sufficient authority. Permittees will focus on enforcing existing ordinances. •

8

Element 2: BMP’s Street Sweeping • Street Sweeping Program evaluations – Permittees evaluate the need to revise street sweeping programs. – City of Norco contracts with a street sweeping company. Conventional and vacuum assisted sweepers are utilized. On a yearly basis the program is evaluated and deficiencies addressed. – City of Riverside plans on purchasing one vacuum assisted sweeper when a conventional sweeper reaches end of life.

Element 2: BMPs Irrigation and Water Conservation Permittees looking to identify BMP practices for future implementation: • City of Norco, a water service provider, is evaluating the potential of tiered water rate schedule • Permittees will continue to collaborate with their utility providers to meet the goals of the UWMP where needed. In partnership with water service providers several permittees offer rebates on irrigation and water conservation devices such as Weather Based Irrigation Controllers. 10

Element 2: BMP’s Pet waste management • Backyard composting factsheet-Countywide project – To provide information on how to compost manure from back yard agricultural operations using easy to build compost bins. – Detailed building plans and material list to encourage Do-it-Yourself projects. – Detailed information on siting to prevent Stormwater contact.

Element 2: BMP’s Pet waste management • Manure Haul Away Program-City of Norco – To provide residents a convenient option for disposing of the manure from their property. – Trash service provider hauls away manure. – Residents pay a fee along with their trash service fee.

Element 2: BMP’s Pet waste management • Doggie Bag Dispensers-City of Riverside – To provide residents a sanitary option for disposing of their pet waste along popular walking trails. – Convenient for residents.
