Column Name: SIUS_WITHOUT_CTL_MECHANISM
Description: A three digit field representing the number of significant industrial users (SIUs) for which a current (unexpired) control mechanism (e.g., permit, sewer use ordinance, or formal contract), as defined in the 10/83 Guidance Manual for POTW Pretreatment Program Development, is required but not yet issued. Alth ough SIUs may be subject to a sewer user ordinance, there may still be a need for the control authority to issue certain S IUs individual control mechanisms to establish more specific pret reatment standards, reporting requirements, monitoring frequencies , etc. (Note: The PCI supplies this information as a percentage of all SIUs; multiply the percentage by the total number of SIUs [data element SIUS] to determine the correct entry for the data element NOCM.)
