1. Stormwater Issues in the Arid Southwest SBIR Phase I Pacific Southwest Solicitation

2. SBIR Stormwater Solicitation Between 40-50% of impaired waters in the Pacific Southwest are from, or suspected to be from, urban sources Between 40-50% of impaired waters in the Pacific Southwest are from, or suspected to be from, urban sources Unique Climatology Unique Climatology –Heavy pollutant loadings –Flashy storms

3. SBIR Stormwater Solicitation 80% of Californians live within a 30 minute drive of the coast 80% of Californians live within a 30 minute drive of the coast Beach usage is higher in CA than in other 49 states combined (U.S Lifeguard Assn.) Beach usage is higher in CA than in other 49 states combined (U.S Lifeguard Assn.)

4. SBIR Stormwater Solicitation Regulatory Framework Regulatory Framework –General Permit System relying heavily on Best Management Practices –Industrial Stormwater Metals, oil and grease, petroleum hydrocarbons Metals, oil and grease, petroleum hydrocarbons –Construction Stormwater Sediments, nutrients, oil and grease, petroleum hydrocarbons Sediments, nutrients, oil and grease, petroleum hydrocarbons –Municipal Stormwater Pathogens and all of above Pathogens and all of above

5. SBIR Stormwater Solicitation Huge universe of sites with varied conditions Huge universe of sites with varied conditions –Construction, Industrial, Municipal Tens of thousands of Industrial Sites in Region 9 Tens of thousands of Industrial Sites in Region 9 BMP effectiveness studies find wide variability depending on site characteristics and operator knowledge BMP effectiveness studies find wide variability depending on site characteristics and operator knowledge –Owner/operator knowledge biggest impediment to efficient BMPs

6. SBIR Stormwater Solicitation Iterative approach to BMP implementation not widely used Iterative approach to BMP implementation not widely used –How to get quick reliable feedback and use it? Reliable water quality data not in the equation Reliable water quality data not in the equation –Sample collection and lab analysis is seen as too complex for most permittees

7. SBIR Stormwater Solicitation Program Needs Program Needs –Real-time monitoring technology for pathogens, oil and grease, metals, and petroleum hydrocarbons for pathogens, oil and grease, metals, and petroleum hydrocarbons Require little supervision, maintenance, and technical know-how Require little supervision, maintenance, and technical know-how Provide data that would allow iterative approach Provide data that would allow iterative approach Technology and output should be user-friendly for those without a background in water quality Technology and output should be user-friendly for those without a background in water quality

8. SBIR Stormwater Solicitation Program Needs Program Needs –Technologies to promote rapid settling of fine suspended particles in stormwater retention basins without adverse water quality effects To be used in construction, municipal, and industrial settings To be used in construction, municipal, and industrial settings

9. SBIR Stormwater Solicitation Program Needs Program Needs –Products or technologies that extract embedded oil or oil products from surfaces (soil, concrete, asphalt) without adverse water quality effects

10. SBIR Stormwater Solicitation Others? Others? –Technologies to remove urban pollutants from stormwater Generally lower concentrations than found in traditional waste streams; cumulative impact Generally lower concentrations than found in traditional waste streams; cumulative impact No adverse water quality effects No adverse water quality effects User-friendly User-friendly
