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

8

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

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

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
