Exxon's Texas refinery reports propylene leak
HOUSTON (AP) — Exxon Mobil Corp. has told Texas environmental regulators there was an eight-week-long, 108,000-pound propylene release at the company's refinery complex near Houston.
Irving, Texas-based Exxon reported to regulators a tubing leak was discovered on June 2 in the chemical plant portion of the sprawling complex in Baytown. The leak was isolated within a half-hour, but Exxon says the leak may have started on April 12.
Propylene is a component of ground-level ozone. According to the report, Exxon isn't permitted to release any propylene at the olefins plant.
Exxon says it won't comment beyond the report it made to the Texas Commission on Environmental Quality.
TCEQ says it is investigating the incident.
