Load reduction measures will be implemented to the extent possible. The development of the implementation plan needs to be integrated with the efforts of the Santa Clara Basin Watershed Management Initiative (SCBWMI).
TMDL product: specific identification of sources and control measures and development of the implementation plan for further action.
Historical data from reservoir and stream samples may be questionable due to inadequate analytical techniques and often unknown detection limits (SCVWD, 1992). There is some ongoing monitoring within the Guadalupe watershed.
Additional Work Needed:
It is necessary to evaluate whether the existing monitoring data can be used for developing a TMDL for mercury. There will be ongoing monitoring needs after completion of the full TMDL. Fish tissue sampling will be used to track progress toward attainment. Methylation monitoring will track success of management efforts.
This section describes the additional work required to adopt the regulatory provisions developed in the course of completing all of the tasks outlined above (i.e., all stakeholder negotiations and technical documentation are completed in the other tasks).
