50 SEPTEMBER 2018 W W W.MATERIALSPERFORMANCE.COM NACE NEWS TCC Provides the Tools to Protect the Environment from Corrosion NACE International TCC Chair Khlefa Esaklul T he vision of the NACE Interna- tional Technical Coordination Committee (TCC) and Techni- cal Activities Department is to develop and disseminate corro- sion-related recognized bodies of knowl- edge, technical standards, and information exchanges for professionals responsible for safeguarding people, assets, and the envi- ronment from the adverse effects of corro- sion worldwide, in keeping with NACE's mission. Today, as people go about their daily lives at home, work, or wherever they go, they, for the most part, are unknowingly affected by the materials used to build their homes, automobiles, public streets, bridges, places of business, etc., and the potential impact on the environment these materials may pose when corrosion is allowed to develop unhindered. More specifically, metallic parts used in building these struc- tures and vehicles have the potential to, and most likely will, develop corrosion at some point in their life cycle. If they are not properly protected by regular corrosion inspection and maintenance programs, these structures and vehicles can fail. Some examples of how people and the environment can be negatively impacted by corrosion left unchecked are found in the Flint, Michigan, USA, water system, where lead was discovered leaking into the drink- ing water of the city's homes and businesses as a result of corroded and degraded lead- containing water pipes. In other areas across the country, petroleum-based prod- ucts have been accidentally released into surrounding areas as a result of pipeline or storage tank failures, most likely caused by corrosion. While loss of containment and leaks of toxic or undesirable elements into the envi- ronment attract everyone's attention, deg- radation or collapse of infrastructure such as bridges, tanks, vessels, and pipelines have as much impact on the environment even if leaks do not occur. Similarly, leaks in water supply infrastructure may not lead to environmental contamination, but it wastes valuable and sometimes scarce water resources. Recent events in the United States have highlighted the apparent lack of corrosion management in our highway infrastructure systems, as major bridges have crumbled and fallen into the water- ways below. And, many industries around the world have experienced machine failures that closed a plant while repairs or replacement of failed equipment took place. Often those failures were caused by corrosion left unchecked. NACE and the TCC mis- sions support the global need to develop processes and procedures for manag- ing corrosion. Everything around us has the potential to develop corrosion, especially when metal is involved. And, the use of metallic materi- als is vastly expanding with the growth of world economies and exploration of new opportunities in every corner of the world to expand commerce, sources of energy, and manufacturing bases. Management of corrosion will have an impact on the environment not only from direct consequences of control of the con- tamination that may result by corrosion of structures like tanks or pipelines, but also in the preservation of energy and scarce resources needed to replace structures sus- ceptible to corrosion through manufactur- ing, construction, and disposal of degraded equipment. Life extension of existing struc- tures also reduces the emissions and other environmental consequences associated with mining, processing, manufacturing, delivering, and installing new structures. NACE, through its various activities, such as developing industry standards, focuses on the management of corrosion to safeguard the environment through dissemi- nation of information and development of standards that guide the user to the best approaches for evaluating the risks of corro- sion and effective options for managing it. This may include selection of materials (e.g., the automotive industry's use of non- metallic materials to produce car and truck bodies, etc.), and utilization of preventive measures, such as coatings, cathodic protec- tion, monitoring and inspection, or enhancement of design and operating pro- cesses, to eliminate or reduce corrosion. These measures have demonstrated that effective corrosion management can be achieved when the industry best practices and standards are fully used. Progress in the use of materials, both metallic and nonmetallic; use of environ- mentally friendly coatings and coating appli-
