at the cost to the cruise operators for running their engines and burning fuel while they are at bertschalent per kilowatt hour rate surcharge that is 3.85 cents per kilowatt hour. it is the cost for plugging in and is the same, so they have an economic incentive to do that. there is cost recovery for the puc for their investment in the pier 27 project. and i will get into the financial approach for the year 70 project, but we are trying to mirror that approach at pier 70. the slide that is up right now describes the potential emissions benefits of the shoreside power project at pier 7, proposed for pure 70. there are major emission savings for reactive compound, party to the matter, -- particulate matter, socks and co2 associated with this facility. we think it is probably one of the biggest emissions projects that the port could implement on a port wide basis at this point. the missions savings are so dramatic -- emissions savings are so dramatic that we have found they fully offset the emissions increases at pier 27, as a result of shutting down the pier 27 shoreside power facility. a
