Proposed GroundwaterTreatment Project

-- MTA Artesia Station in Compton --

June 14, 2012

• Water supply is safe and not impacted

• Treatment system will protect groundwater resources bycapturing shallow contamination with the potential tomigrate to deeper potable aquifers

• No contamination health risk related to this project

• Night work for conveyance piping installation will minimizesite disruption

• Minimal parking space disruption:– Paid-space permits will be purchased for general use– MTA approved temporary ADA parking relocation

• Right Of Entry Agreement has been executed

• Schedule start in June 2012

Boeing Former

• A Boeing predecessor is one of the companies thatleased the land in the 1950s-1960s and utilized it formanufacturing aerospace components resulting in therelease of chemicals to soil & groundwater

• Boeing voluntarily partners with the Regional WaterQuality Control Board (Water Board) on cleanup

• Boeing purchased the site in 2001 to facilitate cleanup andbeneficial-reuse redevelopment; Sold the site in 2005

• 2009: Water Board approved groundwater treatment plan

• 2011 - 2012: Groundwater treatment system installed andoperating at the Boeing Former Compton Site

Former Compton Site Background


• 2007 - 2008: MTA granted Boeing a Right-of-Entry (ROE)permit to install and monitor two groundwater wells

• 2010 - Present: On-going discussions between MTA andBoeing regarding system design and construction

• 2011: SCE and Metropolitan Water District granted pipelineeasements that cross existing Artesia Station easements

• 2012: Boeing obtained ROE from MTA and will begindesign studies for treatment system

Partnership with MTA


Coordination with MTA Departments• Real Estate: Velma Marshall, Thurman Hodges & Maria Garcia

• Environmental: Tom Kefalas & Chris Liban

• Parking: Adelaida Felix & John Roberts

• ADA Compliance: Chip Hazen

• Transportation Planning: Conan Cheung, Michael Sieckert,David Hershenson & Robin Blair

• Communications: Kim Bueno

• Engineering: Aspet Davidian, Jim Yang & Alain Rubin

• Contract Services: Lena Babayan & Steve Yakemonis

• Records Management: Joe Parise & Charlene Aguayo


• Strategic phasing plan will minimize aerial size andconstruction duration

• Boeing will replace obstructed parking by purchasingunused permit spaces and by temporarily relocating ADAcompliant spaces

• Conveyance piping– Installed in drive lanes, at night, to facilitate traffic flow– Installed in segments to minimize construction

footprint

• Traffic-rated trench plates allow normal use during the day
