The Feds get involved

In response to the pollution hazards caused by storm water runoff, the Environmental Protection Agency passed Phase II of the federal Clean Water Act. To comply with this regulation, the Board of Miami County Commissioners and other political subdivisions have coordinated efforts to develop Storm water Management Programs so that pollution caused by runoff in Miami County can be minimized as much as possible.

The Storm Water Management Program consists of the following six components, which are targeted for implementation by the end of 2007:

So what’s the big deal?

As storm water flows over driveways, lawns, and sidewalks, it picks up debris, chemicals, dirt, and other pollutants, and empties into a storm water collection system.

Anything that enters a storm water collection system is discharged untreated into the lakes and rivers we use for swimming, fishing, and providing drinking water.

Now that point-source pollution has been remediated, polluted runoff currently ranks as one of the nation’s greatest threats to clean water.

If each of us does our small part in preventing storm water pollution, the results will be significant. There’s a part we can play in each of the following areas:

  • Household Waste Disposal
  • Lawn Care
  • Auto Care
  • Water Conservation

visual inspection
Visual inspection is a Best Management Practice (BMP )which may identify a variety of problems.

Used to:

Look at runoff for signs of contamination

Look at outfalls in dry weather for signs of

contamination .

Look at storage areas for leaks or stains

VISUAL INSPECTION
visual inspection1
VISUAL INSPECTION

Wet weather inspections should be conducted during the first hour of a storm event. Look for presence of:

  • Floating or suspended material
  • Oil and grease
  • Discoloration
  • Turbidity
  • Foam
  • Odor
visual inspections
Visual Inspections

Dry weather inspections of outfalls:

  • Look for stains, sludge, odor or abnormal conditions

Inspection frequency should be done monthly, and cover both wet and dry conditions.

visual inspections1
Visual Inspections

Visual inspection of storage and processing areas in the plant, focus on:

  • Storage areas
  • Loading and unloading areas
  • Pipes, pumps, valves, fittings
  • Tanks – look for signs of corrosion inside and outside tanks Inspect foundation for deterioration
  • Containment areas
  • Shipping containers

INSPECTIONS FOR NON-STORM WATER DISCHARGES TO STORM SEWERS

PURPOSE: to determine if there are any non-storm water discharges to storm sewers

inspections for non storm water discharges
Inspections for Non-storm water discharges

Sources of non-storm water discharges

may include:

  • dry weather discharges occurring in warm months and in cold months, and during snowmelts.

Inspectors may find illicit point source

outfalls that do not carry storm water.

WHEN IT RAINS

Auto Care

  • Wash your car at a commercial car wash that treats its wastewater, or wash your vehicle on your yard so the water infiltrates into the ground rather than entering the storm drain .
  • Repair leaks promptly and dispose of used auto fluids and batteries at designated drop-off or recycling locations.
inspections for non storm water discharges1
Inspections for Non-storm water discharges

Inspection methods:

Perform visual inspection

  • observe all discharge points during dry weather
  • look for stains, smudges, odors, other abnormal conditions

Review maps of sanitary sewers and storm sewers

Perform dye testing, input dye in sanitary sewer, look for dye tracing in storm outfall

Sampling and chemical analysis is not required by SW WWTP permit

inspections for non storm water discharges2
Inspections for Non-storm water discharges

At least annually, inspect for non-storm

preventive maintenance pm
PREVENTIVE MAINTENANCE (PM)

Preventive Maintenance is a Best Management Practice (BMP)

PM involves the regular inspection, testing, and replacement or repair of equipment and operational systems.

preventive maintenance
PREVENTIVE MAINTENANCE

A PM program can prevent breakdowns and failures through adjustments, repairs or replacement of equipment before a major failure occurs.

PM includes maintenance on storm water catch basins, and spill containment areas, as well as maintenance on equipment in the WWTP.

preventive maintenance1
PREVENTIVE MAINTENANCE

Purpose of PM is to prevent problems before they occur.

Prevent spills and leaks.

No man is an island…

What happens at our location in the watershed, either positive or negative, has a ripple effect on those who live “downstream” from us in the watershed.

We all live downstream

spill response step by step
SPILL RESPONSE, step by step:
  • Is an employee in immediate danger of severe bodily injury?

Leave the site and call Supervisor immediately!!

  • Stop the source of the spill.

If you can’t do this by yourself, call Supervisor immediately!!

spill response step by step1
SPILL RESPONSE, step by step:
  • How large is the spill?

If you believe the spill may leave the plant site, call Supervisor immediately!!

  • Stop the source of the spill, and call the Supervisor.
  • Contain the spill:
    • Place barriers at drains and at doorways
    • If the spill escapes, place barriers at the next control point downstream
spill response step by step2
SPILL RESPONSE, step by step:
  • Assess severity of spill

a. Did spill reach the plant sewer system?

b. Could the spilled material harm the WWTP treatment processes?

c. Is it necessary to shut off the influent screw pumps to protect the WWTP?

d. Are the barriers effective in containing the spill? If not, move downstream to place new barriers.

e. Determine what materials or methods should be used for clean up.

f. Determine if you will need the Vactor truck.

spill response step by step3
SPILL RESPONSE, step by step:
  • Clean up the spill
  • For dry chemicals, use brooms, shovel, sweeper or plow
  • For liquid spills:
    • Shop Vac
    • Vactor truck
    • Sorbents – used to immobilize materials
    • Gels- interact with spill liquid to concentrate and congeal the substance
    • Foams – used to control rate of evaporation
    • Do not use emulsifiers or dispersants
    • Have small bags of absorbent in fueling areas with small drums for storage
    • Absorbents should be swept up, not washed down drains
    • Keep emergency containment and clean up kits available
spill response step by step4
SPILL RESPONSE, step by step:
  • Properly dispose of contaminated materials
  • Fill out reports
spill response step by step5
SPILL RESPONSE, step by step:
  • Post Incident Steps

  • Modify Spill Plan if necessary
  • Replace inventory of sorbents, gels, etc if necessary
  • Incorporate lessons learned into Employee Training
  • Update Plan when a new chemical is introduced or plant modifications warrant an update.

What is Storm Water Runoff?

Storm water runoff occurs when precipitation from rain or snowmelt flows over the ground. Impervious surfaces like driveways, sidewalks, and streets can prevent storm water from naturally soaking into the ground. Consequently, the water “runs off” into a catch basin, a side ditch, or some other storm water collection system that transports the water directly to a river or lake.
