DEEP: Non-RCRA Hazardous Waste

Non-RCRA Hazardous Waste
(Connecticut Regulated Waste)

These are wastes that are not classified as Hazardous Wastes  under Connecticut’s Hazardous Waste Management Regulations, but that are still subject to certain management requirements under Connecticut General Statutes (CGS) Section 22a-454. If a hazardous waste determination indicates that a waste is not hazardous, but the waste conforms to one of the waste types listed below, it must be managed in compliance with the requirements of CGS Section 22a-454. These requirements include:

Haulers and Facilities  Anyone engaged in the business of collecting, transporting or storing  these wastes must have a permit from DEEP. One exception:  a permit is not required for persons that are engaged in the business of transporting waste chemical solids (or “CR05” wastes).

Disposal   No one may dispose  of these wastes without a permit from DEEP.

Generators   Although there are no specific requirements for generators of these wastes, they must be managed properly and stored in an environmentally safe manner. Any mismanagement of these wastes may be a potential source of pollution and subject to enforcement action under CGS Section 22a-432. In the event of a spill, the DEEP's Emergency Response and Spill Prevention Division must be contacted at (860) 424-3338, or at 1-866-DEP-SPIL. If a generator hires a commercial hauler to take away these wastes, that hauler must be permitted by DEEP.  If the generator sends the waste to a treatment, storage or disposal facility located in Connecticut, that facility must also be permitted by DEEP.

Certain of these wastes may be disposed of at a municipal landfill or resources recovery facility (i.e., a “trash-to-energy” plant), provided the facility has been specifically approved to accept the waste.  For more information, contact your solid waste facility, or see the DEEP’s Special Waste Disposal Authorization web page.

The most common type of Non-RCRA hazardous wastes generated and suggested disposal methods are as follows:

Waste Oil Waste oil is a Non-RCRA hazardous waste designated CR02 or CR03 and must be collected and transported to a permitted CGS Section 22a-454 Waste Facility. Certain used oils may be burned on-site in a boiler, industrial furnace, or space heater in accordance with Connecticut's used oil regulations. RCRA Hazardous used or waste oil is regulated according to Section 22a-449(c)-100 through 110 of the Regulations of Connecticut State Agencies (Hazardous Waste Management Regulations).
Antifreeze This is a non-RCRA hazardous waste in most cases, but a RCRA hazardous waste determination should be made at least one time for verification purposes. It is designated CR04 and must be collected and transported by a licensed hauler to a permitted CGS Section 22a-454 Waste Facility.
Asbestos Asbestos wastes are actually not subject to regulation as Connecticut-Regulated wastes, but as "special wastes."  Special wastes are a type of solid waste that may only be disposed of at solid waste facilities that are specifically authorized to accept this kind of waste.  Asbestos may also be disposed of at a solid waste landfill in accordance with the Special Waste Disposal Authorization process.
Solid Paint Wastes Dried paint waste may not be RCRA hazardous, but must be verified non-RCRA hazardous through testing. If non-RCRA hazardous, this waste is designated as CR05 and may be disposed of at a 22a-454 facility, at a landfill, or resources recovery facility (i.e., “trash-to-energy” plant) that is authorized by DEEP to accept such waste.
Grinding Dusts
Grinding dusts may not be RCRA hazardous, but must be verified non-RCRA hazardous through testing. Non-RCRA hazardous dusts and residues designated CR05 may be  disposed of at a 22a-454 facility, at a landfill, or resources recovery facility (i.e., “trash-to-energy” plant) that is authorized by DEEP to accept such waste.
Spill Residues and Contaminated Soil
Certain non-RCRA hazardous spill residues and contaminated soil designated CR05 may be disposed of in a municipal landfill with Special Waste Authorization. The criteria for approval can be dependent upon the volume of waste, the nature of contamination and Soil the disposal site chosen. Each authorization is site specific. Contact the DEEP Waste Engineering and Enforcement Division (WEED) at (860) 424-3023 for authorization information. A general indication of a contaminated soil’s suitability for municipal landfilling is that it contains no listed RCRA hazardous waste, less than 50 ppm toxic organic compounds, and less than 30 times health based standards for inorganics as determined by the Toxicity Characteristic Leaching Procedure.

List of Non-RCRA Hazardous Wastes (Connecticut Regulated Wastes)

Note: These are wastes which are neither characteristically nor listed RCRA Hazardous Wastes as per 40 CFR 261, but a facility permit is required by CGS Section 22a-454 for a person engaged in the business of storage, treating, disposing or transporting*  them.

Waste Number Waste Name Description
CR01 Waste PCBs Any waste material containing or contaminated by PCBs (Polychlorinated Biphenyls) in concentrations at or above 50 ppm (parts per million). These include, but are not limited to, PCB oils, items and equipment.
CR02 Waste Oil Oil or petroleum that is no longer suitable for the services for which it was manufactured due to the presence of impurities or a loss of original properties, and is not miscible in water. These include, but are not limited to, crude oil, fuel oil, lubricating oil, kerosene, diesel fuel, motor oil, non-halogenated oil, and oils that are recovered from oil separators, oil spills or tank bottoms.
CR03 Waste Water Soluble Oil Oil or petroleum that is no longer suitable for the services for which it was manufactured, due to the presence of impurities or a loss of original properties and is miscible in water. These include, but are not limited to, cutting oil emulsions or coolants.
CR04 Waste Chemical Liquid Any wastes that are liquid, free flowing and/or contain free draining liquids and are toxic, hazardous to handle and/or may cause contamination of ground and/or surface water if improperly managed. These wastes may include, but are not limited to latex and solvent paint wastes, grinding wastes, waste sludges, antifreeze wastes and glycol solutions.
CR05* Waste Chemical Solid Any chemical solid or semi-solid from a commercial, industrial, agricultural or community activity. These wastes may include, but are not limited to, grinding dusts, tumbling sludges, scrap plastic and rubber flash, and other ground or chipped waste solid.

*Connecticut General Statutes do not require the transporter to be licensed to transport CR05 (Waste Chemical Solid).
