On November 7, 1990, the Agency proposed to extend the compliance date for the Toxicity Characteristic until January 25, 1993 for produced groundwater from free phase hydrocarbon recovery operations at certain petroleum industry sites-namely, refineries, marketing terminals, and bulk plants.

Made aware of likely disruptions to cleanup operations at these facilities after the Toxicity Characteristic rulemaking process, the Agency concluded that an extension of the compliance date would ensure that these operations would not be interrupted and thereby avoid setbacks in their remediation activities.
