San Francisco Baykeeper to Oppose Cement Plant with Sierra Club — article

Proposed Vallejo Export Terminal and Cement Plant Could Harm the Bay

A bulk shipping port and cement plant proposed along the shores of Mare Island Strait in Vallejo could contaminate San Francisco Bay and nearby communities, Baykeeper recently told Vallejo city leaders. Baykeeper is particularly concerned that the terminal would be used to ship dirty fossil fuels such as coal and petroleum coke, a toxic byproduct of oil refining. It’s likely that toxic dust would be blown and washed into the Bay.

    Here’s what the VMT-Orcem Draft EIR has to say about pet coke…

    “Another possible material which may at some future date be imported is pet coke. Pet coke generally has a higher moisture content than sand/aggregate (5%–10%), but has a high silt content and thus would be imported via a sealed system to minimize fugitive dust. If pet coke is imported, it would be treated in a similar fashion as to what is currently planned for clinker imports. The sealed systems with any associated bag filters/release points would achieve an emission concentration of 2.5 mg/Nm3 (0.0011 grains/dscf) in line with the appropriate BACT limit (Appendix D-1).”

    So it looks like the dust problem would be mitigated, but not the ugly factor. The Draft EIR doesn’t say why we would want to import pet coke to Vallejo, but a bit of searching suggests a shameful transfer to some other destination where it would be guaranteed to cancel out any green benefits of slag cement or VMT-Orcem cap and trade deals. It may have other more benign uses, but pet coke (petroleum coke) is a dirty fuel. A byproduct of processing heavy bitumen piped from the oil sands in Alberta, pet coke is a particularly high emitter of greenhouse gases, and the waste material’s unusually low cost and increasing availability in the United States may derail efforts to shift coal-burning power stations to cleaner natural gas.

      Pet coke combined with biomass waste such as saw dust or wood chips and a binding agent is pressed into briquets , these are used as a cooking fuel , food aid exports often include this fuel with grain meals shipped to countries with food shortages mainly third world .
      otherwise it is an economical fuel for cement kilns and iron smelting . Petcoke is the waste / dregs left over from crude oil refining .

    Can the Bay Keepers come up with some probability statistics? Something better than “could” and “likely”?
