1.1 This guide covers the management of liquid and debris removed from petroleum underground storage tank containment sumps . 1.1.1 This guide does not address and may not be applicable to water bottoms removed from a petroleum underground storage tank. 1.1.2 The liquid waste-stream specific to petroleum underground storage tank sumps is presumed to not contain heavy metals or halogens under normal conditions. The handling of wastes that contain heavy metals or halogens are not contemplated by this guide. 1.2 Units— The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This guide helps regulators, POTW operators, tank owners/operators and service providers to develop protocols for proper management including handling and disposal of sump liquids . 4.2 Liquid and debris may come in contact with petroleum that has leaked from the primary UST system into a containment sump . 4.2.1 Liquid and debris in a containment sump that may have come in contact with petroleum are referred to as sump liquids in this guide. 4.2.2 Federal regulations found in 40 CFR 280.36 require that owners and operators remove liquid or debris from containment sumps . 4.2.2.1 Guide E1990 provides guidance to comply with the requirements of 40 CFR 280.36 relating to liquid and debris in containment sumps . 4.2.2.2 Guide E2681 provides guidance for environmental management of UST systems including inspections for, and removal of, liquid and debris from containment sumps . 4.2.3 When disposed, sump liquids may be hazardous wastes pursuant to federal regulations . States with delegated authority can have their own regulations related the management of hazardous wastes . Tribes, states, and other non-federal governmental entities can have unique hazardous waste management statutes and regulations applicable to the management and disposal of sump liquids . 4.2.3.1 RCRA, 40 CFR §261 governs the identification and listing of hazardous waste while Subpart C, 40 CFR §261.20 identifies the characteristics of hazardous waste . 4.2.4 The recommended procedure for determining whether sump liquids may be hazardous wastes , are found in Appendix X1 . 4.2.5 A discussion of sump test water characterization is found in Appendix X2 . 4.3 Sump liquids should be handled and processed or disposed properly and in compliance with the applicable state, Tribal or federal regulations. RCRA is a federal regulation addressing hazardous wastes but it is generally a state-implemented statute and most states have their own programs that can be more stringent than the federal regulations. This guide does not supersede requirements of the authority having jurisdiction, if any such requirements exist. Specifically, some states and Tribes might have more stringent requirements for VSQGs or might have lower thresholds for VSQG and small quantity generator categories . 4.3.1 Sump liquid should not be disposed on-site unless it has been determined that the sump liquid is not a hazardous waste or the authority having jurisdiction has authorized the on-site disposal.
