The East Coast’s largest and oldest oil refinery is declaring bankruptcy. In its January 22 filing, Philadelphia Energy Solutions (PES) — whose facilities can process 335,000 barrels of oil per day — cited the economic burden of complying with the Renewable Fuel Standard (RFS) as a primary contributor to its fiscal woes. Regardless of the merits of PES’s claims, the RFS is an economic and environmental burden on the United States and ought to be repealed.
