Municipal Liquid Waste Processing

Requirements for facilities that process or treat sludge or liquid wastes in Texas. Links to relevant forms and guidance.

Overview

If you accept municipal liquid waste for processing, you must notify the Texas Commission on Environmental Quality (TCEQ) and obtain a permit or registration unless the activity is conducted at a permitted landfill.

Permit or Registration for Fixed Processing Facility

Operations Requiring a Registration

An MSW processing facility that processes only grease trap waste, grit trap waste from commercial car washes, or septage or a combination of these wastes may do so under a registration according to Title 30 Texas Administrative Code (30 TAC), Chapter 330, Section (§) 330.9(g) Exit TCEQ, if the facility can attain a 10 percent recovery of material for beneficial use from the incoming waste, if the processing facility is located within the permit boundaries of a commission-permitted Type I landfill, or the processing facility is located at a manned public wastewater treatment facility permitted to discharge at least one million gallons per day. Facilities meeting any of these exemptions must obtain a registration by following the procedures in §§330.57–330.73 Exit TCEQ and meeting the operational criteria and design criteria established in Chapter 330, Subchapter E Exit TCEQ.

Operations Requiring a Permit

All other fixed liquid waste processing facilities must apply for a permit under 30 TAC §330.57 Exit TCEQ.

Registration for Mobile Processing Unit

Under 30 TAC §330.9(h) Exit TCEQ, a registration is required for a mobile liquid waste processing unit that processes grease trap waste, grit trap waste from commercial car washes, or septage or a combination of these wastes. Mobile liquid waste processing units must obtain a registration by following the applicable procedures in §330.9(h) Exit TCEQ and §§330.57–330.65 Exit TCEQ and meeting the operational criteria and design criteria in Chapter 330, Subchapter E Exit TCEQ.

Processing at a Permitted Landfill

Under 30 TAC §330.11(d) Exit TCEQ, a separate permit is not required for the storage or processing of grease trap waste, grit trap waste, or septage that contains free liquids if the waste is treated or processed at a permitted Type I MSW landfill, provided the landfill facility complies with the notification requirements of §330.11 (a)-(c) Exit TCEQ. The notification requirement may be satisfied by submitting a permit modification, with notice, following the procedures in §305.70(e) Exit TCEQ. The permit modification should address the applicable rules in §330.63 Exit TCEQ, §330.65 Exit TCEQ, and Chapter 330, Subchapter E Exit TCEQ (such as waste acceptance, waste management unit design, unit closure, and unit operating procedures).

Registration for Experimental Processing Facilities

Under 30 TAC §330.9(i) Exit TCEQ, a permit is not required for an MSW Type VI facility that demonstrates new management methods for processing or handling grease trap waste, grit trap waste from car washes, or septage or a combination of these three liquid wastes. Facilities meeting this exemption must obtain a registration by following the procedures in §330.57–§330.73 Exit TCEQ and meeting the operational criteria and design criteria established in Chapter 330, Subchapter E Exit TCEQ.
