Ammonia

4-7       What is the volume of ammonia to be stored?  What is the concentration level of the ammonia?  What are the security plans and evacuation plans and procedures?

11-3     Will Invenergy be conducting an impact zone analysis for the proposed 40,000 gallons of 19% aqueous ammonia storage at CREC?

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.

22-1 Under the water plan, is it correct that ammonia deliveries increased from 2 per month to 15 per month, or a 13 truckload per month delivery? That equals 26 new trips to and from the site. Please explain the reasons for the increase and the details.
