Ballast Water Treatment Facility Reconfiguration Current Status - PowerPoint PPT Presentation

Ballast Water Treatment Facility Reconfiguration Current Status TOEM Committee RCAC Staff Tom Kuckertz Harvey Consulting, LLC. 9/18/2006 Board Meeting

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 9/18/2006 Board Meeting

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. 9/18/2006 Board Meeting

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 9/18/2006 Board Meeting

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 9/18/2006 Board Meeting

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) 9/18/2006 Board Meeting

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) 9/18/2006 Board Meeting
