K Removal and Disposal of -Used Underground Petroleum Storage Tanks SECTION 1—GENERAL 1.1 Introduction Underground petroleum storage systems that are no longer needed or suitable for product storage must be properly disposed in place or removed in order to avoid future safety or environmental hazards. Because of the nature of the flammable or combustible liquids that are stored in these tanks, hazardous conditions may arise in the work area during disposal in place or removal and subsequent handling of tanks. For this reason, all per- sonnel involved in the procedures outlined in this recommended practice should be familiar with the potential hazards, and be knowledgeable in the appro- priate health and safety measures needed to ensure a safe working environment. 1.2 Scope and Purpose 1.2.1 This publication recommends procedures for the disposal in place, removal, storage, and off-site disposal of underground storage tank systems that have contained flammable or combustible fluids. In general, it outlines requirements, procedures, and operating con- ditions to be followed by contractors, engineers, or other individuals who may be involved in these practices. While this recommended practice specifically addresses underground petroleum storage tank systems at service station facilities, the principles outlined may be applied to similar systems used at other petroleum storage facili- ties. All such work must be accomplished in accordance with federal, state, and local requirements as well as accepted safety standards. Before initiating work, the appropriate government agencies should be consulted concerning applicable regulatory and permit require- ments. 1.2.2 All applicable permits must be obtained prior to beginning any work. Where required, contractors must be approved by local authorities. Contractors, sub- contractors, and their employees responsible for tank abandonment or removal should be familiar with: (a) all applicable safety rules and regulations, (b) the use of equipment and procedures for testing and vapor -freeing tanks, (c) the handling and disposal of the types of wastes likely to be encountered, and (d) the applicable sections of the publications referenced in 1.4. 1.2.3 The procedures outlined in this recommended practice can be carried out without the need to enter the tank. Should tank entry be desired, the procedures outlined in API Publications 2015, 2015A, and 2217 and Recommended Practice 1631 should be followed. 1.3 Special Precautions During the course of underground storage tank removal or in place disposal, workers may be exposed to petroleum hydrocarbon liquids, vapors, or wastes. The precautions in 1.3.1 and 1.3.2 should be observed by all individuals engaged in the procedures discussed in this recommended practice. 1.3.1 TOXICITY CONSIDERATIONS: PETROLEUM SUBSTANCES Users should be aware of appropriate health precau- tions. When high concentrations of petroleum hydro- carbon vapors are inhaled, symptoms of intoxication may result. These symptoms, ranging from simple dizzi- ness to excitement or unconsciousness, are similar to those produced by alcohol or anesthetic gases. If such effects occur, the individual should be removed to fresh air. For minor effects of exposure, breathing fresh air or oxygen results in rapid recovery. If breathing has stop- ped, artificial respiration should be applied promptly. Medical attention should be obtained as soon as possi- ble. Paragraphs 1.3.1.1 and 1.3.1.2 contain special toxicity considerations for benzene and tetraethyl lead, which may be present in petroleum products or wastes found in underground storage tanks. Care should be ex- ercised to minimize exposure to these substances when they are present during the handling of used under- ground petroleum storage tanks. WARNING: Tests have shown that prolonged of repeated exposure to some petroleum substances, in liquid or vapor form, may cause serious illness, in- cluding cancer, in laboratory animals. Although the significance of these test results to human health is not fully understood, exposure to petroleum substances should be minimized. The following health precautions are suggested: a. Avoid skin contact and inhaling vapors.
