What are the specific requirements for the secure storage of unused de-icing fluids to prevent environmental contamination?

The secure storage of unused de-icing fluids to prevent environmental contamination is governed by specific requirements designed to contain spills and prevent runoff. The fluids must be stored in tanks or containers that are specifically designed for the storage of chemicals. These tanks and containers must be made of materials that are compatible with de-icing fluids and must be resistant to corrosion and leaks. The storage tanks and containers must be located in a designated storage area that is designed to contain spills. The storage area should be surrounded by a containment berm or wall that is large enough to hold the entire volume of the largest tank or container, plus an additional amount for precipitation. The storage area must be covered to protect the de-icing fluids from rain and snow. This prevents the fluids from being diluted and overflowing the containment berm. The storage area should be located away from waterways and other sensitive environmental areas. This minimizes the risk of contamination in the event of a spill. Regular inspections of the storage tanks and containers are essential to ensure that they are in good condition and that there are no leaks. The storage area should be equipped with spill response equipment, such as absorbent materials, booms, and containers for collecting spilled fluids. Personnel who handle de-icing fluids must be properly trained in spill prevention and response procedures. The storage area should be secured to prevent unauthorized access. This helps to prevent vandalism and theft. Detailed records of the amount of de-icing fluid stored and used should be maintained. This information is used to track inventory and to identify any potential leaks or spills. In the United States, these requirements are often dictated by the EPA and local environmental regulations. Similar regulations are in place in other countries. Compliance with these requirements is essential for protecting the environment and preventing costly cleanup efforts.
