The San Francisco Bay Area Air Quality Management District staff has reviewed and affirmed the data and Standard Operating Procedures. The monitoring equipment used, while not a federal reference method, is widely used in the environmental field because it is credible and generates reliable data, though it is not employed by the District in its ambient air monitoring network."

[2] WHO guideline values for lead and nickel [3]NOTE 3: According to the U.S. EPA: "The Reference Concentration (RfC) for manganese is 0.00005 mg/m3 based onimpairment of neurobehavioral function in humans. The RfC is an estimate (with uncertainty spanning perhaps an order of magnitude) of a continuous inhalation exposure to the human population (including sensitive subgroups) that is likely to be without appreciable risk of deleterious noncancer effects during a lifetime. It is not a direct estimator of risk but rather a reference point to gauge the potential effects. At exposures increasingly greater than the RfC, the potential for adverse health effects increases. Lifetime exposure above the RfC does not imply that an adverse health effect would necessarily occur." See: http://www.epa.gov/ttn/atw/hlthef/manganes.html There is no 24-hour period health-based standard for manganese. The rationale for comparing the concentration of manganese in air samples from West Berkeley to the U.S. EPA RfC for manganese is based on several months of sampling from locations in close proximity that approximate long-term exposures to manganese. [4] NOTE: Based on the WHO guideline value for nickel and a one per one million risk of cancer per lifetime exposure For WHO Guideline Values, see:http://www.elaw.org/assets/pdf/airqual.pdf

Data Spreadsheet January 8, 2008 • Mark Cherniak, Ph.D.

1. All samples were taken in Berkeley, CA in the 94710 district, unless specified under “Location.” 2. All samples were taken for a 24-hour period. 3. Monitoring condition under “Field Notes & Observations” were determined comprehensively from the following criteria: a. Pacific Steel is operating. Evident by noise, odors, smokestack activity, etc.  b. Wind Direction: if sample was taken downwind of PSC emissions for the following amount of time, each condition was considered: >50% of time downwind = POOR, ~50%-70 of time downwind = FAIR, ~70--90% = GOOD, ~90-100% =OPTIMAL Note: Data for wind directions were taken from http://www.baaqmd.gov c. Wind Speed: Low – Moderate 1-10 mph = OPTIMAL. < 20 mph = POOR. Low to moderate wind speeds ensure particulate fallout will occur in the vicinity of the monitor. Note: Data for wind speeds were taken from http://www.baaqmd.gov 4.     ND = No Data, under “Laboratory Results” Web Spreadsheet prepared by Berkeley Air Monitors - 2008

This report was prepared as a result of work sponsored, paid for, in whole or in part by the Bay Area Air Quality Management District (District). The opinions, findings, conclusions, and recommendations are those of the author and do not necessarily represent the views of the District.

***************

NOTE: The analysis (of the first two samples) shows that while these results are below health-based standards, they are also well above the 2006 Air District Results. It should also be noted that the samples were taken in less than optimal conditions. The result that comes closest to exceeding a health-based standard is the concentration of manganese measured in the second sample (0.032 micrograms per cubic meter), which falls just shy of the U.S. EPA reference concentration for manganese of 0.05 micrograms per cubic meter (based on impacts to neurobehavioral function).

• Note 1: Assume air sample of 7.2 cubic meters: = 24 hours x 5 liters/minute x 1440 minutes/24 hours x 1 cubic meter/1000 liters
• Note 2: U.S. EPA reference concentration for hexavalent chromium.  No RfC available for total or trivalent chromium
• Note 3: No reference concentration available.  National Ambient Air Quality Standard = 1.5 micrograms/cubic meter

The California Air Resources Board (CARB) operates particulate toxic air samplers in San Jose and San Francisco that has test for metal particles as well.  The Bay Area Air District has suggested that the following data be listed as reference information. The results from these test stations in were: 

SAN JOSE (2000)

• Chromium particles were found at at an average concentration of .004 micrograms per cubic meter.  The highest concentration was .015 micrograms per cubic meter.
  
  
• Lead particles were found at an average concentration of .009 micrograms per cubic meter. The highest concentration was .025 micrograms per cubic meter.
  
  
• Manganese particles were found at an average concentration of .017 micrograms per cubic meter. The highest concentration was .065 micrograms per cubic meter.
  
  
• Zinc particles were found at an average concentration of .041 micrograms per cubic meter. The highest concentration was .37 micrograms per cubic meter.

SAN FRANCSICO (2002)

• Chromium particles were found at an average concentration of .003 micrograms per cubic meter.  The highest concentration was .014 micrograms per cubic meter.
  
  
• Lead particles were found at an average concentration of .007 micrograms per cubic meter. The highest concentration was .023 micrograms per cubic meter.
  
• Manganese particles were found at an average concentration of .011 micrograms per cubic meter. The highest concentration was .053 micrograms per cubic meter.
  
  
• Zinc particles were found at an average concentration of .039 micrograms per cubic meter. The highest concentration in was .36 micrograms per cubic meter.
