Section 5: Adaptive Management

Adaptive Management and Revisions​

As part of the adaptive management process, the RAs use information and data acquired from WQIP implementation and water quality monitoring to inform management decisions related to water quality conditions, numeric goals, strategies, and associated schedules. As necessary, RAs may revise the WQIP, respective JRMPs, and/or BMP Design Manuals based upon new data, information, and/or feedback received during the implementation of the WQIP.

Updates and minor modifications to the WQIP, JRMPs, and BMP Design Manuals are presented in this section.

5.1 Updates​

The adaptive management process may prompt updates to the WQIP and respective JRMPs. Updates to the WQIP require the collaboration of the RAs and follow, as applicable, a public participation process similar to that implemented during WQIP development. The public participation process includes soliciting data and information and consultation with the WQIP Consultation Panel. Updates can be provided in the WQIP annual reports or the Report of Waste Discharge (ROWD). WQIP updates may include significant changes to the highest priority water quality conditions, numeric goals, or monitoring and assessment. BMP Design Manual updates or JRMP updates, such as program modifications and/or amendments to the JRMPs, are performed as needed by RAs

Updates to the WQIP, respective JRMPs, and BMP Design Manuals during the reporting period are presented in the following sections.
