SMC FormationSMC Formation
• SMC was formed in February 2001 as a result of:– Increased regulatory focus on stormwater– Lack of scientific knowledge and tools– Common issues facing multiple jurisdictions
• Stormwater regulators, dischargers and SCCWRP formed the SMC as a collaborative programGoal - to develop the technical information necessary to better understand stormwater mechanisms and impacts, and then develop the tools that will effectively and efficiently improve stormwater decision making

Project SelectionProject Selection
• SMC meets 4 times/year to discuss projects and progress
• Projects selected by consensus• Not all SMC members have to participate in all
projects• Outside agencies may participate in projects• Agreements are executed to fund each project• A lead agency is identified to manage the project • Over $1 million of projects funded to date from

Project #2 - Microbial Source Tracking
Project #2 - Microbial Source Tracking
Evaluation of new MST methodologies – human vs. non human and sources (e.g. dog, cow):
• Ribotyping• Antibiotic resistance• Pulsed-field gel electrophoresis• Polymerase chain reaction• Terminal restriction fragment length polymorphism
No method was perfect – host specific PCR was best for human vs. non human

Goal:
To establish relationship between increased impervious cover and physical condition of streams
• Create stream classification system
• Evaluate resiliency of each stream type
• Develop a conceptual model to predict stream channel response to changes in runoff
– Basis for numeric modeling– Guidance for management decisions
A workshop was held to present the results

Results:
• Developed sites were all unstable– 3% - 26% impervious cover
• Control sites were stable, but still exhibited low background rate of change– 0.25% - 1.25% impervious cover– All stream channels are dynamic
• Apparent threshold of response ~ 3%
