North Dakota Industrial Pretreatment Assistance
Program (NDIPAP)

• North Dakota presently does not have an
  EPA-approved Industrial Pretreatment Program.
• EPA is the current regulatory authority for
  industrial wastewater discharges to publicly
  owned treatment works (POTWs).

4
North Dakota Industrial Pretreatment Assistance
Program (NDIPAP)

• NDIPAP was formed to establish consistent
  industrial pretreatment assistance in the state
  of North Dakota.
• The 2-year program was recently extended through
  the end of March 2004.
• NDIPAP is administered by the Energy
  Environmental Research Center.

5
North Dakota Industrial Pretreatment Assistance
Program (NDIPAP)

• NDIPAP is funded through a grant from the
  U.S. Environmental Protection Agency (EPA),
  with nonfederal matching funds from the Red River
  Water Management Consortium
• Jennifer Harris EPA Project Officer
• Curt McCormick EPA Technical Advisor

6
North Dakota Industrial Pretreatment Assistance
Program (NDIPAP)

• Input is provided to NDIPAP by an advisory board
  made up of wastewater treatment professionals
  across North Dakota to
• Develop educational and outreach materials
• Conduct industrial pretreatment workshops
• Offer advice related to pretreatment
• Provide on-site assistance as needed

Industrial Pretreatment

• The act of treating wastewater prior to
  discharge to a Publicly Owned Treatment Works
  (POTW) is commonly referred to as pretreatment.

10
Background

• EPA was created in December 1970 through a
  Presidential executive order.
• The Clean Water Act passed by Congress in 1972
  required the elimination of discharge of
  pollutants into the nations waters.
• The EPA National Pollutant Discharge Elimination
  System (NPDES) Permitting Program requires all
  point-source discharges be permitted.
• The EPA National Pretreatment Program addresses
  indirect discharges from industries.

11
Industrial Discharges

• Direct discharges to a lake or river (point
  source)
• Indirect discharge to a POTW

12
National Pretreatment Program

• The National Pretreatment Program is a
  cooperative effort of federal, state, and local
  agencies that was established to protect water
  quality by reducing the level of pollutants
  discharged by industry and other nondomestic
  wastewater sources into municipal sanitary sewer
  systems.

13
Pretreatment Objectives

• To protect POTWs (wastewater treatment
  facilities) from industrial pollutants that may
  either pass through, and/or interfere with their
  operation, and the resulting negative impacts to
  rivers and lakes as well as to improve
  opportunities to recycle and reclaim municipal
  and industrial wastewaters and sludges.

14
Terminology

• Pass through 40 CFR 403.3(n)
• A discharge which exits the POTW into waters of
  the United States in quantities or concentrations
  which, alone or in conjunction with a discharge
  or discharges from other sources, is a cause of a
  violation of any requirement of the POTWs NPDES
  permit (including an increase in the magnitude or
  duration of a violation).

15
Terminology

• Interference paraphrased from 40 CFR 403.3(i)
• A discharge which, alone or in conjunction with
  a discharge or discharges from other sources,
  both 1) inhibits or disrupts the POTW,
  its treatment processes or operations, or its
  sludge processes, use, or disposal and 2)
  therefore is a cause of a violation of any
  requirement of the POTWs NPDES permit (including
  an increase in the magnitude or duration of a
  violation) or of the prevention of sewage sludge
  use or disposal in compliance with. .
  .applicable statutory provisions and
  regulations. . . .

16
Pretreatment Responsibilities

• Approval Authority (state/EPA)
• Oversee POTW and industrial user (IU) compliance
• Review POTW reports and submissions
• Inspect POTWs and IUs
• Control Authority (POTW)
• Implement pretreatment program
• Regulate IU
• Submit reports to approval authority
• Industrial User
• Comply with pretreatment requirements
• Submit reports to control authority

17
POTWs in North Dakota

• Three general types of municipal wastewater
  treatment facilities
• Lagoons
• Trickling filters
• Activated sludge
• Biological processes provide secondary treatment.
• POTWs are designed to treat wastewater from
  domestic sources (households).
• Industrial discharges can create operational
  problems.

18
POTW Treatment

• Conventional pollutants (domestic sources)
• Biochemical Oxygen Demand (BOD5)
• Total suspended solids (TSS)
• Fecal coliform bacteria
• pH
• Oil and grease
• Toxic pollutants
• May be present in commercial and industrial
  discharges

19

  POTW operations

22
Categorical Standards

General Prohibitions

• No user shall introduce into a POTW any
  pollutant(s) which cause pass through or
  interference.

29
Specific Prohibitions

• All industrial users are subject to specific
  prohibitions that forbid eight categories of
  pollutant discharges
• 1) Discharges with pollutants that create fire
  or explosion hazard in the POTW including, but
  not limited to waste streams with a closed-cup
  flashpoint of 140F.
• 2) Discharges containing pollutants that cause
  corrosive structural damage to the POTW in no
  case pH lt5.0 unless the POTW is specifically
  designed to accommodate these discharges.

30
Specific Prohibitions

• Eight prohibited discharge categories (cont.)
• 3) Discharges containing pollutants in amounts
  causing obstruction to the flow in the POTW,
  resulting in interference.
• 4) Discharges of any pollutants released at a
  flow rate and or concentration that will cause
  interference with the POTW.
• 5) Discharges of heat in amounts which will
  inhibit biological activity in the POTW
  resulting in interference, but in no case in
  amounts such that the POTW treatment plant
  exceeds 104F without approval.

31
Specific Prohibitions

• Eight prohibited discharge categories (cont.)
• 6) Discharges of petroleum oil, nonbiodegradable
  cutting oil, or products of mineral oil origin
  in amounts that will cause interference or pass
  through.
• 7) Discharges which result in the presence of
  toxic gases, vapors, or fumes within the POTW
  that may cause acute worker health and safety
  problems.
• 8) Discharges of trucked or hauled pollutants,
  except at discharge points designated by the
  POTW.

32
Local Limits

• Federal standards do not necessarily address all
  pollutants and are not applied to nonsignificant
  users.
• Local limits may be more stringent than federal
  or state standards.

33
Local Limits

• Protect the POTW and collection system
• Protect workers
• Protect receiving waters
• Improve biosolids utilization or disposal
