THE PROBLEM WITH FOG
................
................
Fats, Oils, and Grease (FOG) in the wastewater
system will cool and solidify in the downstream
wastewater disposal system.
FOG clogs lines in the restaurant, as well as lines in the County
system
FOG builds up in pump stations, disabling level controls and lift
pumps
FOG causes problems at the WWTP, in the head works, digesters,
and post-treatment systems. The higher the treatment level, the
more difficult the issues with FOG.

EPA's National Pretreatment Program, 1973-2003:
Thirty Years of Protecting the Environment
EPA's National Pretreatment Program has led the way to dramatically reduce or eliminate discharges of pollutants to
sanitary sewer systems and to the nation's water bodies. The Program controls a complex array of industrial wastestreams
in order to prevent interference or pass—through of municipal treatment system processes. Without these controls, a
number of harmful pollutants could make their way into the nations' waters. Federal, state, and local partnerships are
central to the successful implementation of the Program. Renewed commitment and support to the Pretreatment Program
will conserve the environmental gains of the last 30 years, strengthen strategic partnerships, and prepare communities to
meet the pollution challenges of the 21st Century.
The Pretreatment Program
Pollutants in industrial wastewater may compromise municipal treatment plants' processes or contaminate the nation's
waters. To protect municipal treatment plants and the environment, the Pretreatment Program requires industrial
dischargers to use treatment techniques and management practices to reduce or eliminate the discharge of harmful
pollutants to sanitary sewers. The Pretreatment
Program is a core part of the Clean Water Act's
National Pollutant Discharge Elimination
System (NPDES), and it has helped communi-
ties:
• Maintain and restore watershed quality, at a
much lower cost than upgrading treatment;
• Encourage pollution prevention;
• Increase beneficial uses of sewage sludge;
• Prevent formation of poisonous gases in the
sanitary sewer system;
Meet wastewater discharge standards; and
Institute emergency—prevention measures.
