RMP Program Objectives & Management Questions

• Question 3: Describe sources, pathways, loadings, and processes leading to pollutant-related impairment in the Estuary.

3.1 - What sources, pathways, and processes contribute most to impairment?

3.2 - What are the best opportunities for management intervention for the most important pollutant sources, pathways, and processes?

3.3 - Are management actions effective in reducing loads from most important sources, pathways, and processes?

* WG specific questions are being developed as part of 5-yr plan

• December 12th

– Reviewed 5-yr plan– Progress report

• Zone 4 Line A• Mallard Island Hg, PCBs, and OC Pest Papers• PBDE Manuscript

• May 22nd

– Zone 4 Line A preliminary data– Reporting: Hg, OC Pest, PBDEs– Pilot and Special Studies Ideas

2007

• First Quarter Goals– Complete Zone 4 Line A reporting– Rewrite 5-yr plan– Sampling (Z4LA, Guadalupe)– Modeling

• Guadalupe watershed model (Oram et al.)

• Watershed specific sediment loads (Lewicki et al.)
