The Assessment, TMDL Tracking And ImplementatioN System (ATTAINS) data exchange allows ENPartners to submit 303(d)/305(b) water quality data, Total Maximum Daily Load (TMDL) information, and support program goals aligned with both submissions processes.
A goal of the ATTAINS data exchange is to move the Integrated Reporting process to a paperless process using Exchange Network technology. The ATTAINS data flow allows for the two-way exchange of data between EPA and EN Partners, including States, Tribes and Territories. It also allows for the publishing of IR data via web services that support the integrated vision of the Water Quality Framework.
The ATTAINS system replaces the existing Assessment Database (ADB), the National TMDL Tracking System (NTTS). ATTAINS also replaces the Clean Water Act Integrated Reporting, Water Quality Assessment, Impaired Waters -OWIR data exchange. ATTAINS supports node and node client data exchanges, cloud-based data entry. EN Partners currently using the OWIR-ATT data should plan to transition to the ATTAINS data flow. The legacy OWIR-ATT data flow will be discontinued in 2018.
