  1. Overview of PretreatmentProgram Regulations40 CFR Part 403 Pretreatment 101 Short Course 8/3/09 Addison, Texas David Hardgrave ODEQ State Pretreatment Coordinator

  2. CFR 403.1 Purpose This part implements sections of the Clean Water Act and establishes responsibilities of the various levels of government, industry & the public to implement National Pretreatment Standards to control pollutants which pass through or interfere with treatment processes in Publicly Owned Treatment Works (POTWs) or which may contaminate sewage sludge

  3. CFR 403.1 Applicability The Pretreatment Regs apply: • To POTWs which receive WW from sources subject to pretreatment standards • To States applying for NPDES delegation • To any new or existing source subject to pretreatment standards • To pollutants from non-domestic sources

  4. CFR 403.2 Objectives • To prevent the introduction of pollutants into POTWs which will interfere with the operation of a POTW, including interference with its use or disposal of municipal sludge; • To prevent the introduction of pollutants into POTWs which will pass through the treatment works or otherwise be incompatible with such works; and • To improve opportunities to recycle and reclaim municipal and industrial wastewaters and sludges

  5. 403.3(a)-(w) Definitions A few pertinent ones to look up and be familiar with: (i) The term Indirect Discharge or Discharge means the introduction of pollutants into a POTW from any non-domestic source… (j) The term Industrial User or User means a source of Indirect Discharge (k) Interference means…. (p) Pass Throughmeans … (t) Pretreatment requirements means… (v) Significant Industrial User means…

  6. Pass-through - Discharge which exits the POTW into waters of the U.S. in quantities or concentrations which, alone or in conjunction with other sources, results in a violation of any provision of the POTW’s discharge permit Interference- Discharge which, alone or in conjunction with other sources, inhibits or disrupts the POTW’s treatment processes or sludge disposal practices and is the cause of a discharge permit violation and/or prevents proper sludge disposal

  7. 403.4 State or Local Law Nothing in this regulation is intended to affect any Pretreatment Requirements, including any standards or prohibitions, established by State or local law as long as the State or local requirements are not less stringent than any set forth in National Pretreatment Standards, or any other requirements or prohibitions established under the Act or this regulation. Etc, etc, etc……

  8. 403.5 National Pretreatment Standards • (a)(1) General prohibitions. A User may not introduce into a POTW any pollutant(s) which cause Pass Through or Interference.

  9. 403.5 National Pretreatment Standards (b) Specific prohibitions.In addition, the following pollutants shall not be introduced into a POTW: • (1) Pollutants which create a fire or explosion hazard…including, but not limited to, wastestreams with a closed cup flashpoint of less than 140 °F or 60 °C using the test methods specified in 40 CFR 261.21; • (2) Pollutants which will cause corrosive structural damage…but in no case Discharges with pH lower than 5.0, unless the works is specifically designed to accommodate such Discharges; • (3) Solid or viscous pollutants in amounts which will cause obstruction to the flow…resulting in Interference; • (4) Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a Discharge at a flow rate and/or pollutant concentration which will cause Interference…

  10. 403.5(b) Specific prohibitions (cont.) • (5) Heat in amounts which will inhibit biological activity… resulting in Interference, but in no case heat in such quantities that the temperature at the Treatment Plant exceeds 40 °C (104 °F) unless the Approval Authority, upon request of the POTW, approves alternate temperature limits; • (6) Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass through; • (7) Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems; • (8) Any trucked or hauled pollutants, except at discharge points designated by the POTW

  11. 403.5 National Pretreatment Standards (cont.)(Local Limits) c) When specific [LOCAL] limits must be developed by POTW (1) Each POTW developing a POTW Pretreatment Program shall develop and enforce specific limits to implement the prohibitions listed in paragraphs (a)(1) and (b) of this section. Each POTW with an approved pretreatment program shall continue to develop these limits as necessary and effectively enforce such limits. (2) All other POTWs shall, in cases where pollutants contributed by User(s) result in Interference or Pass-Through…develop and enforce specific effluent limits for IUs, and all other users, as appropriate, which, together with appropriate changes in the POTW Treatment Plant's facilities or operation, are necessary to ensure renewed and continued compliance with the POTW's NPDES permit or sludge use or disposal practices.

  12. 403.6 Categorical Standards • Effluent Guidelines with Pretreatment Standards for Existing or New Sources (PSES or PSNS) (will be further discussed in a following “101” module) • 40 CFR Chapter I, Subchapter N, CFRs 405 to 471 Can find ALL of them @ http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?&c=ecfr&tpl=/ecfrbrowse/Title40/40tab_02.tpl

  13. CFR 403.7 Removal Credits • Too lengthy to discuss in this forum • Revolves around your POTW’s removal efficiency • Has been rarely utilized nationwide • Interesting concept, hassle to implement and grant

  14. 403.8(a) Who Must Develop a Pretreatment Program? • POTWs: • with combined design flow > 5 MGD, AND • receiving flow from CIUs, AND/OR • receiving pollutants from IUs which may cause pass through or interference. • Approval Authority may require program be developed, regardless. • NPDES States may assume responsibility.

  15. 40 CFR 403.10(e), 5 States(CT, VT, AL, MS, & NE) EPA State POTWs with no program required IU IU IU - Approval Authority - Industrial User - Control Authority - IU

  16. 403.8(f)(1) Legal Authority –AMUST!! • State law • Local regulations • Sewer Use Ordinance or • Rules and Regulations (New Model Ord. NOW Available) The Backbone of a Local Pretreatment Program
