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
Industrial User Classification
  • Nonsignificant Industrial Users
  • Significant Industrial Users (SIUs)
  • Categorical Industrial Users (CIUs)

20
Pretreatment Standards
  • National Pretreatment Program identifies
  • Specific requirements that apply to all IUs.
  • Additional requirements that apply to SIUs.
  • Certain requirements that apply only to CIUs.

21
Significant Industrial Users
  • Listed categorical industry (CIU)
  • Industries not listed as categorical, but
    significant in one or more of the following

    process wastewater
  • Contribute 5 or more to the average dry weather
    hydraulic or organic load to a POTW
  • Have reasonable potential to adversely affect
    POTW operations

22
Categorical Standards
  • Categorical pretreatment standards are national,
    uniform, technology-based standards that apply to
    specific industrial categories.
  • Limit the discharge of specific pollutants
  • Existing source (PSES) and new source (PSNS)
    standards
  • 51 categories listed in Code of Federal
    Regulations (40 CFR Parts 405471)

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
