Sept 27 (Reuters) - A U.S.-based refinery owned by

Canada's Cenovus Energy ( CVE ) will pay a $19 million penalty and spend

an estimated $150 million in capital investments after violating

emissions rules, U.S. authorities said on Friday.

The penalty is part of a settlement reached between the Lima

refinery in Ohio and the U.S. Justice Department and the

Environmental Protection Agency. In a joint statement, the EPA

and the department said the plant had emitted illegal amounts of

benzene and other volatile organic compounds.
