Emissions through the following methods: Implement a comprehensive plan by which leaks are identified through field testing of valves and other connections using EPA Method 21 Identify, document and repair leaks within a defined time frame Reduction of permitted leakage limits for valves, connections and pumps It is important to note that EPA Method 21 is intended only to locate and classify leaks in currently installed valves; It should not be used as a direct measure of mass emission rates from individual sources, nor to certify whether a valve can be classified as low emission. Additionally, EPA Method 21 is not a valid field test for fugitive emissions. SEE MORE ABOUT REDUCING LEAKAGE IN REFINERIES What is a Low Emissions (Low-E) Valve? In conjunction with the implementation of an LDAR program and as noted above, consent decrees may establish that all valves purchased for future maintenance, repair and operations (MRO) projects, as well as new projects, must be valves.
low emissions. The content of many EPA consent decrees, however, leaves the method of determining what constitutes a Low-E low emissions valve up to the plant. There are generally several methods to classify a valve as low emission. It is the plant's decision to accept the valve manufacturer's supply of the following: A written guarantee that the valve will not leak more than 100 parts BYB Directory per million for five years A written warranty, certification, or equivalent documentation that the valve has been tested in accordance with good and generally accepted engineering practices and has demonstrated leakage of no more than 100 ppm A seemingly simple solution to documenting the purchase of low-emission valves is for manufacturers to provide a written guarantee that their valve will not leak greater than 100 parts per million for five years.
However, the plant operator must consider the consequences if the valves do leak. What compensation is available in the event of a valve leak? Is the warranty only limited to replacing the leaking valve? Are the costs associated with valve replacement recoverable? Relying on the manufacturer's warranty leaves the plant open to the possibility that, whether voluntarily or not, the manufacturer may continue to supply valves with leaks greater than 100 parts per million. There are enough uncertainties in plant operations to only rely on the manufacturer's warranty when test methods are available to determine whether a valve meets the required leak rate.
