Much has been made about the possible issue of air pollution that might be caused by Clark Pacific locating in Woodland.
The truth is that it is not much of an issue at all.
When I talked to the people at the Air District today guess what they said? They already issued permits for the site because the air emissions would be so small.
When I asked about past complaints in West Sacramento I was told that Clark Pacific had not had a problem in the last decade.
You can see some of the information about air issues in the attached documents and in the box below.

We will bring out the truth on this. One piece at a time. Then we can broaden our scope a little.

The District has issued 7 Authorities to Construct (ATCs) to Clark Pacific for the proposed operation at the former Spreckels location. This includes one portable sandblasting operation, one concrete batching operation and five small natural gas fired steam generators. Please find a description of the air pollution risk from each category below:
Sandblasting
While there are published regulatory studies of toxic emissions from dry outdoor blasting of metal objects, there are no known studies for outdoor blasting of the proposed concrete materials. Emissions from abrasives certified by the California Air Resources Board (CARB) for permissible dry outdoor blasting, typically do not contain materials listed in the District Risk Management Plan and Risk Assessment Guidelines (RMPRAG) (i.e. - heavy metals, etc.) nor materials classified as Hazardous Air Pollutants (HAPs) or Toxic Air Contaminants (TACs). The District considers the toxic risk from this portable abrasive blasting operation to be de minimis. In addition, the source proposed a minimum of 70% wet abrasive blasting for the sandblasting at the site, a process which is expected to reduce particulate emissions.
Concrete Batching
The District did perform a risk screening assessment for the proposed concrete batching operation at the site. This screening evaluation included an assessment of possible emissions of heavy metals and crystalline silica and the results indicated that the proposed project emission levels were below the screening levels listed in the District RMPRAG policy.
Natural Gas Fired Water Heaters
The District did perform a risk screening assessment for the five natural gas fired water heaters at the site. The results indicated that the proposed project emission levels were below the screening levels listed in the District RMPRAG policy.
I have included the District ATCs and engineering evaluations for portable sandblasting, concrete batching and one of the natural gas fired water heaters. |
