The United States and the state of Arkansas filed an enforcement action last week against ExxonMobil Pipeline Company and Mobil Pipe Line Company in federal district court in Little Rock. The complaint concerns the March rupture in the companies’ Pegasus Pipeline in Mayflower, Ark.
The 20-inch diameter pipeline—originally built in the 1940s—carried heavy Canadian crude oil, which the complaint alleges spilled into a neighborhood and nearby waterways. Residential evacuations were ordered and cleanup efforts are ongoing.
