Work to Date

• Remediation work began July 2010

Remediation work began July 2010

• As of January 17, completed

removal of 14,020 tons (597 trucks worth) of contaminated soil from areas A, C/D and J

• Completed removal of crushed

concrete and asphalt stockpiles for recycling

• Ongoing stormwater and site

management activities

Dust Control and Air Monitoring

• Air monitoring has been taking place

Air monitoring has been taking place at the site since dismantlement work began in 2007

• Approved dust control plan on file with

BAAQMD

• All air monitoring results are reported

to DTSC and the Bay Area Air Quality Management District (BAAQMD)

Daily Dust Control Measures

Measures in place on work days: p y

• Spraying water to suppress dust:
• Watering trucks
• Hand‐held hoses

W t i t th f li

• Water misters on the fence line
• Applying soil tackifier
• Washing truck tires
• Covering truck loads

g

• Fence screening
• Sweeping of adjacent streets
• Covering soil stockpiles
• Lowered on site speed limit
• Lowered on‐site speed limit

Air Monitoring Results: Through December 14, 2010, all readings were below

the conservative trigger level set for the project.

Adaptive Solutions

There were 3 days in December (12/15, 12/16 and 12/20) with air y ( ) monitoring readings above the project’s conservative trigger level. In response, we adapted dust control efforts to include:

• Additional water misters
• Additional wind screen along fenceline

Additi l t li ti

• Additional water application
• Increased use of soil tackifier

9

Adaptive Solutions

There have been 6 days in January (1/4*, 1/10, 1/14, 1/17, 1/18, 1/19) y y ( ) with air monitoring readings above the project’s conservative trigger level. In response, we are adapting dust control efforts to include:

• Modified water misters
• Covered exposed bedrock

Adj t d t li ti

• Adjusted water application process
• Modified equipment/excavation methods

*Reading exactly at trigger level

10

Adaptive Solutions

We are continuing to adapt the project’s dust control measures. Steps g p p j p that we are in the process of implementing include:

• Sprinklers for soil stockpiles
• Different type of soil tackifier
• Other water-based dust control measures
