Guidance manual for preventing interference at POTWs

Technical Report ·
OSTI ID:6030314
The manual was developed by EPA to aid publicly owned treatment works in identifying, tracking, and mitigating interference episodes caused by discharges of nondomestic wastes. The basic regulatory requirements are explained in the manual and technical guidance is provided to help POTW operators detect and determine the sources of interference. The manual is divided into four sections: (1) is introduction, background, definition of interference; (2) is detecting interference (types of interference: chronic inhibition; upset conditions; chrnoic inhibition; upset conditions); Interference-Causing Substances (conventional pollutants; metals/other inorganics; organic compounds); Sewer Collection System problems; Plant Operations (observation; instrumentation; analytical results); and Wastewater Monitoring (POTW influent; other POTW locations; Inhibitory Effects Testing); (3) Source Identification (chronic discharges; isolated spills/unauthorized discharges; rapid screening techniques); and (4) Mitigation (treatment plant control; pretreatment and source control; legal and enforcement remedies). Appendix A contains case studies which were conducted over a period from December 1985 to March 1986. Since then the status of some of the activities at the case study sites are likely to have changed. Appendix B is Interfering Substances.
