On October 27, 2014, the Integrated Compliance Information System (ICIS) schema is being upgraded to Version 5.0. ICIS v5.0 includes a new Air module and changes to the National Pollutant Discharge Elimination System (NPDES) module for using a new Compliance Monitoring Identifier as the key field for all Compliance Monitoring-related submissions.
Because previous versions of the ICIS-NPDES schema will no longer be supported, any State submitting permit, DMR, compliance monitoring, etc., data to ICIS-NPDES must ensure their submissions XMLs conform with ICIS v5.0, which is available at https://www.exchangenetwork.net/data-exchange/icis-npdes/.
