Book Description
Leaking underground storage tank systems present an environmental concern and a potential health hazard. It is well known that leaks in the piping associated with these systems account for a sizeable fraction of the leaks. EPA has established performance standards for pipeline leak detection systems, and published a document presenting test protocols for evaluating these systems against the standards. This paper discusses a number of facets and important features of evaluating such systems, and presents results from tests of several systems. The importance of temperature differences between the ground and the product in the line is shown both in theory and with test data. The impact of the amount of soil moisture present is addressed, along with the effect of frozen soil. These features are addressed both for line tightness test systems, which must detect leaks of 0.10 gal/h (0.38 L/h) at 150% of normal line pressure, or 0.20 gal/h (0.76 L/h) at normal line pressure, and for automatic line leak detectors that must detect leaks of 3 gal/h (11 L/h) at 10 psi (69 kPa) within an hour of the occurrence of the leak. This paper also addresses some statistical aspects of the evaluation of these systems. Reasons for keeping the evaluation process "blind" to the evaluated company are given, along with methods for assuring that the tests are blind. Most importantly, a test procedure is presented for evaluating systems that report a flow rate (not just a pass/fail decision) that is much more efficient than the procedure presented in the EPA protocol, and is just as stringent.

Book Description
The U.S. Environmental Protection Agency (EPA) was introduced on December 2, 1970 by President Richard Nixon. The agency is charged with protecting human health and the environment, by writing and enforcing regulations based on laws passed by Congress. The EPA's struggle to protect health and the environment is seen through each of its official publications. These publications outline new policies, detail problems with enforcing laws, document the need for new legislation, and describe new tactics to use to solve these issues. This collection of publications ranges from historic documents to reports released in the new millennium, and features works like: Bicycle for a Better Environment, Health Effects of Increasing Sulfur Oxides Emissions Draft, and Women and Environmental Health.

Book Description
Ageing infrastructure and declining water resources are major concerns with a growing global population. Controlling water loss has therefore become a priority for water utilities around the world. In order to improve efficiencies, water utilities need to apply good practices in leak detection. Leak Detection: Technology and Implementation assists water utilities with the development and implementation of leak detection programs. Leak detection and repair is one of the components of controlling water loss. In addition, techniques are discussed within this book and relevant case studies are presented. This book provides useful and practical information on leakage issues.

Book Description
Over the brief history of automatic leak detection, perhaps 40 years, there has been a great deal of experimentation and conjecture along with the application of real and meaningful science and technology. This is not unusual in a young field, but it has interfered with the development of a broad understanding of the underlying concepts and realities. This book places the need for leak detection on pipelines in a societal context using both a regulatory and a risk-based approach. It develops the applicable science, starting with first principles. It explores the technology available for implementation, shows how to estimate and monitor performance, and discusses how to maintain and ensure consistency over time. This book is an excellent reference for professionals who develop and apply leak detection systems, as it discusses the fundamentals of leak detection science and technology, including the mathematics on which the fundamentals are based. It also includes key information about threats pipelines encounter, along with the underlying concepts, capabilities, and limitations of leak detection technology. This information will be of great value to regulators as well as to petroleum industry executives, safety and technology managers, and operations managers.

Book Description
Subsea repairs and inspection are costly for petroleum and pipeline engineers and proper training is needed to focus on ensuring system strength and integrity. Subsea Pipeline Integrity and Risk Management is the perfect companion for new engineers who need to be aware of the state-of-the-art techniques. This handbook offers a "hands-on" problem-solving approach to integrity management, leak detection, and reliability applications such as risk analysis. Wide-ranging and easy-to-use, the book is packed with data tables, illustrations, and calculations, with a focus on pipeline corrosion, flexible pipes, and subsea repair. Reliability-based models also provide a decision making tool for day-to-day use. Subsea Pipeline Integrity and Risk Management gives the engineer the power and knowledge to protect offshore pipeline investments safely and effectively. Includes material selection for linepipe, especially selection of standard carbon steel linepipe Covers assessment of various types of corrosion processes and definition of anti-corrosion design against internal as well as external corrosion Gives process and flow assurance for pipeline systems including pipeline integrity management

Book Description
In 1990, EPA released a series of "Standard Test Procedures for Evaluating Leak Detection Methods" to define consistent, rigorous procedures for determining the performance of underground storage tank leak detection methods. Each test procedure outlines one or more ways to evaluate the performance of a class of leak detection devices. Liquid- and vapor-phase detectors are tested for their ability to detect the presence of petroleum components in controlled laboratory settings. Pipeline leak detectors, tightness testing methods and automatic tank gauging systems are tested for their ability to reliably differentiate between non-leaking systems and systems with simulated leaks of specified sizes. Statistical inventory reconciliation methods are tested using real inventory data from tight tanks, including some simulated leaks. The results of these preliminary evaluations are discussed and compared. The test procedures allow manufacturers to demonstrate the effectiveness of their methods and help tank owners to ensure that the equipment or service they purchase complies with applicable regulatory requirements.
