Identifying & Permitting Industrial Users
Finding the industries in your service area and bringing them into a permit structure that reflects their actual discharge.
Industrial User Survey
An effective program starts with an active survey of the service area — you can't permit businesses you don't know about.
Significant Industrial User (SIU) Determination
Not every industrial user requires a full permit — categorical users, high-volume dischargers, and those with significant pollutant potential qualify as SIUs.
Permitting and Local Limits
Industrial discharge permits translate federal categorical standards and local limits into specific, monitorable requirements for each user.
Pattern of Noncompliance
A single exceedance is an event; multiple exceedances within a defined window constitute a 'pattern of noncompliance' triggering escalating enforcement.
