Exemptions from Industrial and Hazardous Waste Permitting
Now that you have determined what type of solid waste you generate, the next step will be to determine if management of the waste is exempt from permitting.
But remember that the following requirements apply even if the activity is exempt from permitting:
- You must still comply with the rules for proper waste management (see subchapters C and H of 30 Texas Administrative Code (TAC) Chapter 335
; - You remain subject to the restrictions detailed in 30 TAC §335.4
, which are general prohibitions against polluting the water, creating a nuisance, or endangering public health and welfare. - You might need to comply with notification requirements in accordance with 30 TAC §335.6
and comply with associated waste audits; - You might still need to register your activities and comply with associated waste audits;
Exemptions from the requirements for a permit fall into 6 general groups:
- Conditionally exempt small quantity generators
- Farmers disposing of pesticides
- On-site Processes
- Types of Treatment Units:
- Certain Waste Management Activities:
- Specific Types of Facilities:

Conditionally Exempt Small Quantity Generators
See 30 TAC §335.2(e)![]()
A permit is not required for the on-site storage of hazardous waste by a conditionally exempt small quantity generator. Conditionally exempt small quantity generators are described in 30 TAC Section §335.78
.
The TCEQ may grant a one-time 30 day extension to store hazardous waste without a permit beyond the allowed accumulation time. Such extensions are granted on a case-by-case basis if hazardous wastes must remain on-site due to unforseen, temporary, and uncontrolled circumstances.
Contact us if you have any questions.
Farmers Disposing of Pesticides
See 30 TAC §335.41(d)(4)![]()
A farmer may dispose of waste pesticides without a permit provided that the waste pesticides were from his own use, and provided that each emptied pesticide container is triple-rinsed, and the pesticide residues are disposed of on his or her own farm in a manner consistent with the disposal instructions on the pesticide label.
Contact us if you have any questions.
Less than 90-Day Storage
See 30 TAC §335.69(a)(1)![]()
A permit is not required for the storage or processing of hazardous waste generated on-site if the waste is stored in tanks, in containers,in containment buildings, or on drip pads, provided that storage is for less than 90 days, and that the unit meets the requirements of 30 TAC §335.69
.
A storage period of 180 days is allowed without a permit for a small quantity generator as defined in 30 TAC §335.2
. In the case where a small quantity generator must transport his or her waste more than 200 miles for disposal, a 270-day storage period is allowed without a permit.
The TCEQ may grant a one-time 30 day extension to store hazardous waste without a permit beyond the allowed accumulation time. Such extensions are granted on a case-by-case basis if hazardous wastes must remain on-site due to unforseen, temporary, and uncontrolled circumstances.

Flow-through Tanks
See 30 TAC §335.69![]()
As of March 29, 1994, tanks with flow-through capabilities may qualify for the less than 90-day accumulation time exemption. To qualify for this exemption, the owner or operator must demonstrate that the total operating volume of the tank is replaced every 90 days or less (i.e., retention time is less than or equal to 90 days). The tank must also meet certain restrictions regarding the accumulation of solids in the tank.

Addition of Absorbent Material in a Container
See 30 TAC §335.41 (d)(3)![]()
A permit is not required for the addition of absorbent material to waste in a container, or the addition of waste to absorbent material in a container, provided that these actions occur at the time the waste is first placed into the container. The requirements for maintaining proper container condition and for ensuring compatibility of waste with containers must be met.

On-site Disposal of Non-Hazardous Industrial Solid Waste
See 30 TAC §335.2(d)(1)and (2)![]()
No permit is required for the on-site storage, processing, or disposal of industrial solid waste which is not hazardous waste, if that waste was generated on-site.
Contact us if you have any questions.
Certain Recycling Operations
See 30 TAC §335.24![]()
A permit is not required for the management of industrial recyclable materials described in 30 TAC §335.24
.
The state and federal rules pertaining to the industrial waste recycling exemption are complex, and a simple description of how they apply is difficult to make. Only the recycling process itself is exempt; storage and disposal of hazardous wastes are still subject to permitting requirements.
See Can I Recycle Some of My Industrial or Hazardous Wastes? (RG-240) for more information.
If you have a process that meets these requirements fill out Notification Form for Recycling Hazardous and Industrial Waste and/or Generator Notification Form for Recycling Hazardous or Industrial Waste and send them to us at the address indicated on the forms.
Contact us if you have any questions.
Elementary Neutralization Units
See 30 TAC §335.41(d)(1)![]()
A permit is not required for an elementary neutralization unit, which is a device that is used for neutralizing wastes that are hazardous only because they are corrosive. The unit must meet the definition of a tank, tank system, container, transport vehicle, or vessel as described in 40 CFR §260.10
--Definitions and 30 TAC §335.1
. This exemption also applies to nonhazardous waste as stated in 30 TAC §335.2(d)(3)
.

Wastewater Treatment Units
See 30 TAC §335.41(d)(1)![]()
A permit is not required for a wastewater treatment unit, which is a device that is part of a wastewater treatment facility that has a wastewater discharge permit authorized through the Clean Water Act. Please note that, in accordance with Senate Bill 1281 passed during the 79th Legislative Session, a commercial industrial solid waste facility discharging into a Publicly Owned Treatment Works is required to obtain a permit as of June 1, 2006. Wastewater treatment units must meet the definition of a tank. This exemption also applies to nonhazardous waste as stated in 30 TAC §335.2(d)(3)
.

Emergency Response Cleanup
See 30 TAC §335.41 (d)(2)![]()
A permit is not required for treatment or containment activities during the immediate response to: a discharge of a hazardous waste, an imminent and substantial threat of a discharge of hazardous waste, or a discharge of a material that, when discharged, becomes a hazardous waste.

Contact us if you have any questions.
Totally Enclosed Treatment Facilities
See 30 TAC §335.41(b)![]()
A permit is not required for a totally enclosed treatment facility, which is a facility used for the treatment of hazardous waste generated on-site and directly connected to an industrial production process.
