The site contains two refineries (at Point Breeze and Girard Point). What is the story for each refinery?

While the question is a bit open-ended and capable of multiple interpretations, we interpret this question to be generally inquiring about the ownership history of the two refineries. As specified on the website, Point Breeze (which includes AOIs 1, 2, 3 4, and 8) was formerly owned by Atlantic Richfield Company (ARCO) and purchased by Atlantic Refining & Marketing Company in 1985 and Sunoco subsequently purchased Atlantic in 1988. Girard Point (which includes AOIs 5, 6 and 7) was formerly owned by Chevron and was purchased by Sunoco in 1994. In 2012, the complex was transferred from Atlantic (as to Point Breeze) and Sunoco (as to Girard Point) to Philadelphia Energy Solutions (PES).
