Hydrogen

9-1       Please see the article attached hereto, especially the highlighted sections, and provide more information regarding the proposed hydrogen tube trailer/generation, and all related safety issues, including responses to the claims set forth in the attached article and whether Invenergy has considered any alternatives in addition to utilizing truck trailer mounted hydrogen tube racks or a hydrogen generator.

9-2       ­In particular, please provide all safety plans and designs concerning possible problems that could arise with the hydrogen.

9-3       Please explain whether and how you intend to use monitors to make this safer, and which monitors you propose to use.

9-4       Please explain the safety measures that will be put in place for the hydrogen being transported by Town roads to the plant.

9-5       Please confirm whether in this power plant it would be necessary to replace a tube trailer every one or two weeks, and if not, how often the replacements will be required.

9-6       Please confirm that you are proposing to comply with the supply and siting requirements of the National Fire Protection Association, and provide specifics. 

9-7       Please explain how you will have the installation site become a classified area limited in use pursuant to the National Fire Protection Association.

15-1     Are you aware of whether any databases exist for accidents that have occurred at power plant sites, including, but not limited to, accidents that involve chemical spills, hydrogen accidents, fuel oil accidents, and/or ammonia accidents?  If so, please provide information regarding any such databases, including, but not limited to, electronic links, if any exist.

15-4     What onsite resources at the facility will be provided to address onsite accidents, including chemical spills and other possible accidents?  Please provide all details.

15-5     What do you expect the Town of Burrillville should do regarding service levels needed to address possible accidents at the facility, including chemical spills?

17-1     Is there any possibility, no matter how small, that there could be an explosion at the Spectra/Algonquin compressor station which could cause an explosion at the Invenergy plant?  If it is your opinion that this is impossible, please explain.  If it is your opinion that it is in any way possible, please explain the conditions under which this could occur, the likelihood of this occurring and your reasoning.  Also, if this is possible, no matter how unlikely, please calculate the size of the blast area that would be affected by such an explosion.

17-2     Is it at all possible that a problem at the Invenergy plant could cause an explosion at the Spectra/Algonquin compressor station?  If it is your opinion that this is impossible, please explain.  If it is your opinion that it is in any way possible, please explain the conditions under which this could occur, the likelihood of this occurring and your reasoning.  Also, if this is possible, no matter how unlikely, please calculate the size of the blast area that would be affected by such an explosion.

17-3     Please explain/calculate the probability of a certain blast events occurring, including the Algonquin Station exploding, the hydrogen storage tubes or generator igniting, and/or the proposed CREC facility itself exploding.

17-4     Please conduct an ALOHA (Area Locations of Hazardous Atmospheres (“ALOHA”) Model developed by the EPA and the National Oceanic and Atmospheric Administration) analysis to determine the extent of the impact area of any possible explosion at the Invenergy facility and/or the Spectra/Algonquin facility, no matter how remote the possibility.
