EPA is pleased to announce that an upgrade to version 3.0 of the ICIS-NPDES schema has been approved and will be available starting Monday, November 21, 2011.

Version 3.0 will allow NPDES compliance monitoring inspections to be transferred electronically to EPA’s ICIS system by States and Tribes along with the permit and DMR data currently being supported by this data flow.  In addition, the permit data families have been expanded by adding the capability to delete and terminate permits, and enter dates into permit schedules for historical permits.

The exchange is currently in production for inspections, permits, and effluent data families, including Discharge Monitoring Reports. Other data families, such as enforcement actions and violations, will be developed in the future.

Version 2.1 will continue to be supported, but will only allow basic permit, master general permit, general permit covered facility, unpermitted facility, permit tracking event, narrative condition/permit schedule, permitted feature, limit set, limit, and DMR data to be transferred electronically to EPA’s ICIS system by States and Tribes.
