1 MRP Pollutants of Concern Selenium and PBDE Provisions Monday November 20, 2006 Richard Looker - RWQCB

2 Mea Culpa Bad News: I failed to get these provisions into the distributed draft due to an oversight - sorry. Good News: provisions are straightforward and not onerous for this permit term.

3 The Provisions (1)  Characterize distribution of PBDEs & selenium in Bay urban areas to determine:  a) PBDEs & selenium presence in runoff  b) if PBDEs & selenium are distributed relatively uniformly in urban areas, and  c) are there particularly high concentration source areas?  Report in Year 2.

4 The Provisions (2 & 3)  Provide information to allow for calculation of loads from urban conveyances:  Report in Year 3.  Identify control measures and/or management practices to eliminate or reduce discharges of PBDEs or selenium conveyed by urban runoff  Report in Year 4.

5 Issues to work out  How extensive should the effort be for the characterization?  Similar to PCB/Hg effort through Kinnetic  How robust should the methodology be for the loads calculation?  can be rough bounding exercise based on collected data.  Consider doing dioxins and legacy pesticides analysis at the same time.
