There have been numerous studies supporting the unsustainable impact of the Delaware City Refinery's water intake system on aquatic life, but little action or enforcement. Before the state allows the plant to renew its permit, which has been expired for over a decade, the plant must upgrade its equipment to the standards of Best Technology Available.
Why is this important?
The Delaware City Oil Refinery water intake system, built in the 1950s, kills millions of fish a year with its antiquated screening system. The refinery must use its vast state financial aid to improve this system, since it is not only particularly harmful, but inexpensive to fix.
