Regulations
  • Clean Water Act of 1977
  • Federal Water Pollution Act of 1972

3
Definition of Pretreatment(part 1)
  • Pretreatment often refers to the treatment of
    industrial wastewater at the industrial facility
    prior to discharge to a local sewer system

4
Why Pretreat?
  • Remove harmful compounds
  • Recover valuable materials
  • Reduce sewer fees

5
Definition of Pretreatment(part 2)
  • Pretreatment is also used to refer to the
    administrative activities involved in regulating
    discharges from industries into the sewer system,
    as in pretreatment program.

Goals of Pretreatment Program
  1. Protect Collection System
  2. Protect the Sewer Workers
  3. Prevent Interference or Pass-Through
  4. Protect the Biosolids for beneficial reuse

Gasoline
  • Gasoline is the number one source of explosions
    in the sewer system
  • One gallon of gasoline when vaporized mixed
    with air has the same explosive force as 14
    sticks of dynamite

Regulatory Requirements
35
General Prohibitions
  • Pollutants which create a fire or explosive
    hazard
  • Solids or viscous substances which cause an
    obstruction in the flow
  • Petroleum oil, nonbiodegradable cutting oil or
    mineral oil
  • Any wastewater having a pH lower than 5.0 pH
    units

36
More Prohibitions
  • Any wastewater containing pollutants which cause
    interference at the POTW
  • Any wastewater having a temperature which will
    inhibit biological activity at the POTW
  • Any pollutants which result in toxic gases,
    vapors, or fumes that may cause worker health and
    safety problems

37
Local Limits
  • POTW Capacity
  • POTW Treatability
  • Water Quality
  • Land Application (Biosolids)
  • Air Quality

38
Permits
  • Issued by the Control Authority
  • Enforced by the Control Authority, the State, and
    EPA

39
Significant Industrial User
  • Over 25,000 gallons/day of process wastewater
  • More than 5 of the POTW Flow or Strength
  • Any deemed by the POTW
  • Categorical

40
Categorical Standards
  • Metal Finishing
  • Pharmaceutical
  • Organic Chemical Manufacturing
  • Battery Manufacturing
  • Aluminum Forming
  • Copper Forming

60
  • We apologize for the violation and hope that our
    experience will be a lesson to others that
    environmental laws must be respected

61
  • The Cost of Noncompliance Should NOT be less than
    the Cost of Compliance
