What is Stormwater? Why should we care?

Wastewater vs Stormwater

Cuyahoga River Fire 1952 Cleveland, Ohio

Clean Water Act

CGP

(Construction General Permit)

NPDES Permits

(National Pollutant Discharge Elimination System)

MS4

(Municipal Separate Sewer System)

IGP

(Industrial General Permit) Or

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

• n 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
• Can affect your sampling
• Away from property
• Must sample run-off points

Potential Pollutant Sources

How do we identify them?

Potential Pollutant Sources

Structural BMPs

• Physical Objects
• More Expensive

Non-Structural BMPs

• Cheaper
• Not physical

How to Conduct an Inspection

What if it were raining right now?

Corrective Actions

They are good to have!

Sampling

• 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!

What do you sample?

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
• AC Condensate
• Water free of pollutants and has not

come in contact with industrial

• perations
• Process water
• Wastewater
• Oil
• Wash-water
• 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

• All states required by 2020
• Trending towards public
