BWTF Reconfiguration
- Reduction of explosive risk primary driver
- Facility modifications
- PWSRCAC’s participation in planning
- Alyeska requested NTP from JPO
- EPA comments
- Comments and questions

Reduction of Explosive Risk
- Texas City disaster – 13 fatalities in process area
- 90s Tanks –
– Planned tie-in to vapor control (will control HAPs emissions)
- 80s Tanks –
– Planned nitrogen inerting temporarily and then removal from system (Nitrogen blanket does not control HAPs emissions)
- DAF cells –
– Flood DAF weir and planned replacement of DAF cells with closed induced gas flotation (IGF) process (Not emission control, sends dissolved HAPs to BTTs)
- Splitter box –
– Sealed (Not emission control, sends dissolved HAPs to BTTs)
- BTTs –
– Planned instrumentation for optimum control of microbes. May control emissions to an unknown extent.

PWSRCAC’s Participation in Alyeska’s Planning Process
- Engineering reviews
– 80s Tanks replacement – Recovered crude to be pumped to East Tank Farm – 90s Tanks skimmers – 90s Tanks tying to vapor control
- Implementation
– Flooding DAF weir –
- leaks in dam and recycle mode appears to be problematic
– Temporary sealing of Splitter Box

DAF Weirs and Splitter Box
9/18/2006 Board Meeting
Raised Water Levels in Weir System Greatly Reduce Turbulence and HAPs Emissions
9/18/2006 Board Meeting
Splitter Box Temporarily Sealed

JPO Is Insisting on a NEPA Review of the Overall Planning for BWTF Modifications
- Alyeska requests an NTP at end of June 2006
– Performance specification inferable but not traceable to planned reconfiguration activities.
- JPO schedules release of an Environmental
Assessment in September 2006
- JPO issues “emergency” NTP for BWTF
instrumentation in August 2006
– Dissolved oxygen probes in BTTs – Salinity probes in BWTF – BTEX Analyzer at output from DAF cells – BTT recycle pump (back to 90s Tanks)

Alyeska Request for BWTF Reconfiguration NTP
Flooded DAF weir – (Dam) (2005) Tank 81 standby (2006) Standby of DAF cells 5 & 6 (2006)
- West BTT standby (2006)
- No 80s tanks (2006)
- Vapor control for Tanks 93 and 94 (2007)
- Induced gas flotation (DAF replacement) (2008)
