The oil is very dirty oil. We now have adequate oil and adequate natural gas without refining this filthy product. Not only is it dirtier to refine, it is also much more difficult to cleanly extract and produces much more greenhouse gases in its extraction. It is also much more difficult to clean when the inevitable pipe accident occurs. All of these argue against this project. It is not needed, it is dangerous to air, water, soil, and climate. Yes it produce good temporary jobs. I strongly encourage our government to use these workers repair our crumbling bridges, roads, water systems. We all know this absolutely needs attention.
We will need to find a mechanism to pay for infrastructure repair. Perhaps a financial transaction tax.
