Hi Rob,

As a very brief intro to you: Green Inc. (my company) and three other Alberta, Canada companies are currently investigating the future, local Alberta, Ca nada $/ton SO2 and NOx removal costs (life-cycle NPV levelized costs) for refineries and other industries, and were suggested by Shell to consult the attached FR USEPA source document, wh ich contains a series of tables that lists “cost effectiveness $/ton” data for various performance scenarios – albeit with ve ry few details about the engineering and financial analysis assumptions made for the $/ton values.

A quote from upper page 35861 of the attached FR document:

The costs and emission reductions to comply with final subpart Ja were estimated from those starting points as well. For further detail on the methodology of these calculations, see Docket ID No. EPA–HQ–OAR–2007–0011. When considering and selecting emission limitsfor the final rule, we evaluated the costeffectiveness of each option for new sources separately from reconstructed and modified sources. In most cases, our selections for each process unit and pollutant were consistent for
modified and reconstructed units and new units. In this section, we are presenting our costs
and emission reductions for the overall rule.

I explored the docket on (13 website links): http://nlquery.epa.gov/epasearch/e pasearch?option1=yes&option2= no&option3=no&option4=no&option5 =no&search_pdf=all&typeo fsearch=area&querytext=do cket+EPA-HQ-OAR-2007- 0011&submit=Go&originalqueryt ext=docket+EPA-HQ-OAR-2007-

I did not find any explicit documents (e.g., one or severa l report .pdf files) with the details on the $/ton

costs derivations tabled in the attached FR document.

Would you please be so kind to guide me (e.g., webs ite links or e-mail file attachments from you) regarding the FR quoted cost info sources?

Should you require additional info please contact me.Yours truly
