Keystone XL is the name of the particular project. The owner is Trans-Canada Pipeline Corp.

Phase III of the Keystone project -- a line from Cushing, OK to Houston -- was completed in January, 2014.

So, yes, they now operate in Texas. But it's an "off-ramp", not an "on-ramp". Pipelines are one-way streets, y'know.
