Industrial Pretreatment Fundamentals
What a pretreatment coordinator manages, and why it's tested alongside plant process topics.
Local Limits vs. Categorical Standards
Categorical standards set a federal floor; local limits are calculated specifically for your plant's capacity.
Significant Industrial Users (SIUs)
Flow or categorical thresholds that trigger individual permitting and monitoring requirements.
Enforcement Response Structure
A documented, escalating sequence applied consistently across all industrial users.
Industrial Waste Survey
The baseline inventory of industrial dischargers required to establish and maintain a pretreatment program.
FOG (Fats, Oils & Grease) Programs
Restaurant and food service grease trap requirements aimed at preventing collection system blockages.
Sampling & Monitoring Requirements for SIUs
How often and what parameters a Significant Industrial User must self-monitor and report.
Pretreatment Program Annual Reporting
The documentation a control authority submits annually demonstrating program implementation to the approving regulatory agency.
Removal Credits & Combined Wastestream Formula
Advanced pretreatment calculations adjusting categorical limits when a plant provides significant pollutant removal or blends waste streams.
