Introduction and Background
Location Population Served – Around 60,000 Phase II Coverage – 60+/- Sq. Miles Storm Sewer – 100+ Miles of Pipe Receiving Waters – 450 Miles of Stream Lee County ChattahoocheeTallapoosa
What is an Outfall Reconnaissance Inventory?
Involves –Field Location –Documentation –Evaluation –Mapping –Characterization of all permitted and unpermitted discharges to either the MS4 or its receiving waters. City of Auburn * This includes identification and inventory of other WQ related concerns Outfall Reconnaissance Inventory Iron Floc Anyone?
An Outfall Reconnaissance Inventory Should be Done to: Meet/Exceed IDDE component of MS4 permit **Can be Low Cost Familiarization of jurisdiction ID other concerns (erosion etc.) ID maintenance concerns Assess All SS aerial crossings ID BMP opportunities (restoration) Most importantly - to gain intimate knowledge of your system
An Outfall Reconnaissance Inventory Should be Completed: ASAPASAP Reevaluate every 5 years or soonerReevaluate every 5 years or sooner Should arguably be done prior to implementation of ANY on the ground BMP other than education and outreachShould arguably be done prior to implementation of ANY on the ground BMP other than education and outreach Should be performed in dry conditions, preferably at least 72-hours after any significant storm eventShould be performed in dry conditions, preferably at least 72-hours after any significant storm event
Planning, Prioritizing, and Managing Field Investigations
How to Plan for Outfall Reconnaissance Gather all existing information on storm- sewer system Gather all cartographic data (GIS if available) Identify all TMDL or 303(d) listed waters Delineate receiving basins into manageable units Prioritize your schedule according to variables of impairment and/or local knowledge
Know Your Limits. Jurisdictional Limits That Is!
SIMPLEADVANCED Gather Available Data
Prioritization and Scheduling Watersheds with Approved TMDL’s Watersheds with 303(d) Listed Waters Source Water Protection Area (Drinking Water Source) Watersheds Designated as Critical Habitat Outstanding Water Resources

Data Review and Analysis
Progress – Year 4 3 Watersheds Completed 225 Miles of Stream Surveyed 1,161+ Outfalls Mapped and Assessed 734 Water Quality Concerns Identified 150+ Sanitary Sewer Aerial Crossings Inspected Vast Increase in Local Knowledge Base!
By The Numbers 79% 19% 1% Unlikely Potential Suspect Obvious
By The Numbers 83% 17% No Yes
92% 8% Highlights Importance of Preventative Maintenance!! By The Numbers Yes No
