Transport committee  Let me just add one component to what my colleague has said: the transmission price. The tolls of the TransCanada are an issue. Clearly, to take natural gas from western Canada to eastern Canada costs a lot in terms of the tolls that are in existence. This is an issue that is being dealt with by the NEB.

Transport committee  Is that a sophisticated way of saying a carbon tax?

Transport committee  I'm not understanding what you're saying.

Transport committee  You're not talking about carbon; you're just talking about NOx and SOx and mercury in particulate.

Transport committee  There is a difference between Canada and the U.S. The electricity regulation that is supposedly coming down that was in the Canada Gazette talked about CO2 emissions but did not talk about NOx, SOx, and mercury, whereas the EPA is actually looking at the NOx, SOx, and mercury in particulate, particularly in PM2.5.

Transport committee  It can be between $8,000 and $12,000, depending on the tank you choose.

Transport committee  That's correct.

Transport committee  It's $1,500 to install and currently $4,000 for the appliance itself, so that's $5,500 total.

Transport committee  For the Honda Civic in the U.S. it's about a $3,000 difference.

Transport committee  No.

Transport committee  I think the economics would probably say between three and five years.

Transport committee  What would you consider long term?

Transport committee  That's a possibility.

Transport committee  I would think so. In fact, the retailers are now starting to do long-term contracts with Encana. We did a long-term deal with Northwest utilities in Oregon to make sure we closed in on a pricing that they could pass along to their customers. You're starting to see that throughout the U.S., given the natural gas prices.

Transport committee  I had said, with regard to education, that we put on summits here in Ottawa to make people aware of natural gas for transportation. We've led by example with our own fleet, particularly with our rig operations and our collaboration with OEMs. We have been working with the OEMs to come out with product.
