Technical Resource Document for Obtaining Variance from the Secondary Containment Requirement of Hazard Waste Tank Systems. Volume 1. Technology-Based Variance

摘要

On July 14, 1986, EPA promulgated revised standards for hazardous waste storage and treatment tank system (51 FR 25422). These regulations require that all new and existing hazardous tank systems be provided secondary containment with release monitoring. EPA recognizes that the goal of protecting human health and the environment might be achieved in ways other than secondary containment. Therefore, tank system owners or operators may apply for a variance from the secondary containment requirements of the hazardous waste tank standards. Both risk-based and technology-based variances can be obtained. The document was developed to provide hazardous waste tank system owners and operators information for submitting a request for a variance. It was written in two volumes; Volume 1 covers technology-based variances, and Volume 2 covers risk-based variances. Technology based variances as discussed in Volume 1, can be granted if the tank system owner/operator can show that the use of new technology and/or alternative operating procedures together with location characteristics, will enable a release to be contained, detected, and removed as effectively as if a secondary containment technique were employed.
