What is Stormwater? Why should we care? 5
Wastewater vs Stormwater
Cuyahoga River Fire 1952 Cleveland, Ohio
Clean Water Act NPDES Permits (National Pollutant Discharge Elimination System) IGP MS4 CGP (Industrial General Permit) (Municipal Separate Sewer System) Or (Construction General Permit) MSGP (Multi-Sector General Permit)
SWPPP (Stormwater Pollution Prevention Plan) What is a SWPPP? How do I make one?
SWPPP? Too Simple?
Site Maps What needs to be shown on a stormwater map? - Discharge Locations - Drainage Areas - Flow Lines - etc
Site Map Real examples from finalized SWPPPs
Area Map? There are easier ways to download your map...
Run-On VS Run-Off - Towards property - Away from property - Can affect your sampling - Must sample run-off points
Potential Pollutant Sources How do we identify them?
Potential Pollutant Sources JACKPOT!
Best Management Practices (BMPs) Or Control Measures
Spill Prevention E x p o s u r e M Sweeping i n i m i s z r a e t t l i i F o n t u o p s n w o D Best Management Practices (BMPs) Training Housekeeping Or Control Measures Trash Bin Lids Erosion and Preventative Sediment Control Recordkeeping Maintenance
Structural BMPs - Physical Objects - More Expensive Cheaper ● Not physical ● Non-Structural BMPs 20
How to Conduct an Inspection What if it were raining right now?
Corrective Actions They are good to have!
Sampling What do you sample? SIC codes or categories ● Usually lab required ● How often and when ● change state to state How to calibrate a pH ● meter in 3 different languages!
How to Collect Samples Gloves! ● Bottles! ● pH strips or meter! ●
Keep track of it all with records! ● Where’s your proof! ● CoC ● Observations
NSWD (Non-Stormwater Discharge)
Authorized VS Unauthorized - Fire System Flushing - Process water - AC Condensate - Wastewater - Water free of pollutants and has not - Oil come in contact with industrial - Wash-water operations - Any liquid that is suspect of having potential pollutants
Regulator Enforcement! ● Have you been inspected? ● What is a regulator looking for?
Risks ● NOV: Notice of Violation Fines - up to $53,484 ● /day /violation ● Lawsuits Don’t throw your sampling money down the drain!
Special Conditions Permit Exemptions
Online Reporting What you need to know ● All states required by 2020 ● Trending towards public availability
