Column Name: SIGNIFICANT_INDUSTRIAL_USERS
Description: A four digit field representing the number of significant industrial users (SIUs) which discharge to a particular pretreatment control authority's treatment works (i.e., a POTW with an approved pretreatment program). Significant industrial users include all categorical industrial users and significant non-categorical industrial users. (Note: Although SIU is defined in the 7/86 Pretreatment Compliance Monitoring and Enforcement Guidance and may be defined in regulation in the future, some POTWs still use a slightly different definition of SIU. At this time, report the number of identified SIUs subject to the POTW's definition of SIU.)
