Exemptions

TRI regulations provide exemptions for specific scenarios. These exemptions allow for a facility to not consider quantities of toxic chemicals for certain threshold determinations and waste management calculations. To learn more about an exemption, please click on the exemption title below.

Exemption Summary
Articles Listed toxic chemicals contained in articles may be exempt from threshold determinations and waste management calculations.
De Minimis The de minimis exemption allows covered facilities to disregard certain minimal concentrations of listed toxic chemicals in mixtures or trade name products.
Coal Extraction Listed toxic chemicals that are manufactured, processed, or otherwise used during coal extraction activities at facilities in NAICS code 2121 (Coal Mining) are not subject to TRI threshold determinations and waste management calculations.
Intake Air and Water Exemption applies to toxic chemicals present in process water and non-contact cooling water as drawn from the environment or from municipal sources, or toxic chemicals present in air used either as compressed air or as part of combustion.
Laboratory Activities Toxic chemicals manufactured, processed, or used in a laboratory under the supervision of a technically qualified individual are exempt from threshold determinations and waste management calculations. This exemption does not apply in certain situations (e.g., specialty chemical production).
Janitorial or Facility Grounds Maintenance Listed toxic chemicals used in janitorial or other custodial or facility grounds maintenance activities (e.g. bathroom cleaners, fertilizers) are exempt from threshold determinations and waste management calculations.
Metal Mining Overburden Listed toxic chemicals that are constituents of overburden which are processed or otherwise used by facilities in NAICS codes 212221, 212222, 212230 or 212299 are not subject to threshold determinations and waste management calculations.
Motor Vehicle Maintenance The use of products containing toxic chemicals for the purpose of maintaining motor vehicles operated by the facility is exempt from threshold determinations and waste management calculations.
Operators of Establishments on Leased Property If two or more persons, who do not have any common corporate or business interest (including common ownership or control), operate separate establishments within a single facility, each such person shall treat the establishments it operates as a facility for purposes of this part. See 40 CFR 372.38(f) for more details.
Owners of Leased Property The owner of a covered facility is not subject to reporting if such owner's only interest in the facility is ownership of the real estate upon which the facility is operated. This exemption applies to owners of facilities such as industrial parks where the owner has no other business interest in the operation of the covered facility.
Personal Use Certain uses of foods, drugs, cosmetics, or other personal items containing listed toxic chemicals are not subject to TRI threshold determinations and waste management calculations. Supplies of such products within the facility, such as in a cafeteria or infirmary, are included in the exemption.
Structural Component of the Facility Listed toxic chemicals contained in certain uses of structural components of a facility are exempted.

Training

The basic concepts training will help you determine whether your facility has triggered EPCRA Section 313 (TRI) reporting requirements for one or more chemicals. This training includes topics on reporting thresholds, reporting forms, and reporting exemptions as well as an introduction to electronic reporting.

The advanced concepts training assumes a basic understanding of TRI requirements. This training focuses on recent changes to requirements, advanced guidance on threshold determinations and reporting, and reporting for chemicals with special requirements. More information on electronic reporting is also included.
