Standard Guide for Environmental Management of Underground Storage Tank Systems Storing Regulated Substances

SIGNIFICANCE AND USE
4.1 Environmentally sound management of underground storage tank systems involves a broad range of preventative maintenance activities directed toward preventing accidental releases of regulated substances, and effectively detecting and responding to such releases when, and if, they do occur. Numerous technical guidelines are presently available addressing specific procedures for release prevention and response for underground tank systems, including guidelines for tank system design, installation, operation and maintenance, leak detection, spill control, periodic equipment inspections, corrective action for affected environmental media, tank system closure, and operator training. This guide presents an overview, identifying key management considerations and referring the user to other related ASTM standards and industry guidelines for more detailed information.  
4.2 Tank System Design and Installation—The first step in environmentally sound management of tank systems is to design and install the tank system so as to minimize the potential for release of regulated substances to the environment. This guide addresses key considerations related to the types of tank systems to be used, compatibility of regulated substances to construction materials, types of spill containment and overfill prevention devices, corrosion protection, leak detection proper installation practices, and system operation.  
4.3 Preventative Maintenance—Even for properly designed and installed tank systems, practical measures are needed to detect and terminate leaks and respond to releases in a timely manner so as to minimize regulated substance losses and associated environmental effects. This guide reviews general considerations including release detection measures, possible indicators of a release, appropriate record-keeping procedures, tank system inspection, equipment testing, response planning and release control measures. Some preventative maintenance activities are recommended while ot...
SCOPE
1.1 The framework discussed in this guide is limited to facilities with underground storage tanks (USTs) storing regulated substances at ambient temperature and atmospheric pressure. This guide is not intended to provide detailed technical specifications for implementation of the approaches described in this document, nor to be used as an enforcement tool, but rather to identify the important information used for environmental management of underground tank systems. The term “must” is used where United States federal requirements apply. References to ASTM standards and other industry guidelines have been provided to address implementation of the approaches discussed in this guide. Many states and some local agencies have adopted rules that place additional responsibilities on the owners/operators of UST systems. Refer to state and local regulations that may contain additional requirements. It is not possible to identify all considerations or combinations of conditions pertinent to a unique underground storage tank system.

Standard Guide for Three Methods of Assessing Buried Steel Tanks

SIGNIFICANCE AND USE
4.1 This guide provides three methods for determining the suitability of a buried steel tank to be upgraded with cathodic protection.  
4.2 This guide may be used to assess any UST, including non-regulated USTs.  
4.3 This guide provides three alternative methods but does not recommend any specific method or application. The responsibility for selection of a method rests with the user.  
4.4 This guide has specific requirements for vendor provided information which should be requested and reviewed by the user.
SCOPE
1.1 This guide covers procedures to be implemented prior to the application of cathodic protection for evaluating the suitability of a tank for upgrading by cathodic protection alone.  
1.2 Three procedures are described and identified as Methods A, B, and C.  
1.2.1 Method A—Noninvasive with primary emphasis on statistical and electrochemical analysis of external site environment corrosion data.  
1.2.2 Method B—Invasive ultrasonic thickness testing with external corrosion evaluation.  
1.2.3 Method C—Invasive permanently recorded visual inspection and evaluation including external corrosion assessment.  
1.3 This guide presents the methodology and the procedures utilizing site and tank specific data for determining a tank’s condition and the suitability for such tanks to be upgraded with cathodic protection.  
1.4 The tank's condition shall be assessed using Method A, B, or C. Prior to assessing the tank, a preliminary site survey shall be performed pursuant to Section 8 and the tank shall be tightness tested pursuant to 5.2 to establish that the tank is not leaking.  
1.5 While this guide provides minimum procedures for assessing a tank's condition, this guide does not provide minimum installation procedures or requirements for upgrades of the tank by cathodic protection.  
1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.7 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.  
1.8 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.
