California Public Records Act (PRA) Request for Communications between Dan Hirsch and Rick Brausch During Drafting of SB-990 and the 2010 AOCs

A public records act (PRA) request was made to DTSC for communications between Daniel Hirsch and DTSC.

Documents provided so far have unearthed email communications demonstrating ...

  1. coordination between Hirsch, Brausch, and staffers of one-time State Senator Shiela Kuehl during drafting of SB-990,
  2. attempts to incorporate SB-990 into the 2007 Consent Order,
  3. coordinated efforts between Hirsch, DTSC and CalEPA to prevent EPA listing SSFL on the NPL
  4. constant communication between Hirsch and Brausch during the August 2009 coup ousting Riley and the replacement of the Riley revised consent order with the Movassaghi/Brausch revised consent order
  5. Hirsch was initially alarmed at Movassaghi's idea of including background into the equation, believing that it undermined the risk assessmennt foundation of SB 990
