EPCRA > Overview

A power plant may store a variety of materials in aboveground tanks and/or smaller containers, and include diesel fuel for backup generators, fuel oil for boilers, or various acids and caustics used as water treatment additives. Depending on what is stored in tanks at a power plant and the quantities of the materials, reporting requirements under the Emergency Planning and Community Right to Know Act (EPCRA) associated with the presence of hazardous chemicals and extremely hazardous substances that might be stored on site may be applicable to your power plant.

The reporting requirements of EPCRA generally apply when you are required to maintain material safety data sheets (MSDSs) and you have hazardous chemicals present at any one time in amounts of 10,000 pounds or greater, or extremely hazardous substances (EHS) above 500 pounds or their threshold reporting quantity (whichever is lower). The aggregate amount of each hazardous substance and extremely hazardous substance must be included to determine if threshold quantities are exceeded. However, EPCRA exempts substances in the same packaging/concentration as used in or purchased for home use, so, for example, some materials in the form typically purchased in a hardware store may not be reportable. Also, some other exemptions apply to certain types of research laboratories, hospitals or other research facilities.

The form the notification must take depends on what state or local authorities require. In some cases, a facility must submit an MSDS; in others, a letter with a list of the chemicals used at the facility is sufficient. Many fire departments and local emergency planning committees require, in place of the MSDS or list, that you submit a more detailed "Tier II" reporting form.

After inventorying chemicals campus-wide, the chemicals should be aggregated to determine if reporting thresholds have been exceeded. A facility is defined as: "all buildings, equipment, structure, and other stationary items that are located on a single site or on contiguous or adjacent sites and which are owned or operated by the same person (or by any person which controls, is controlled by, or under common control with, such person)." If facilities are non-contiguous, aggregating the chemicals must be done separately for each location.

Although EPCRA reporting is typically the domain of the college or university's EH&S or Facilities Management offices, you may benefit from the information provided in this section of the EVC regarding EPCRA regulatory requirements.
