Sewage Sludge: Am I Regulated?

Lists activities involved in the disposal or use of sewage sludge, water treatment plant sludge, and domestic septage that require permitting from, registration with, or notification of the TCEQ. Links to pages with more complete information on requirements for each activity.

Before dealing with sludge in Texas, consider whether you need to contact the TCEQ:

  • To process or dispose of Class B sewage sludge or apply it to the land, you must first obtain an individual permit. Class B sewage sludge is a classification of sewage sludge based on the levels of disease-causing organisms (pathogens). For a complete legal definition of Class B sewage sludge, see Title 30, Texas Administrative Code (30 TAC), Section 312.82Exit TCEQ, Subsection (b).

  • To apply domestic septage to the land, you must first register with the TCEQ. Domestic septage is the material pumped from septic tanks and similar wastes—but not chemical toilet waste. For a complete legal definition of domestic septage, see Title 30, Texas Administrative Code (30 TAC), Section 312.82Exit TCEQ.

  • To apply water treatment sludge to the land, you must first register with the TCEQ. Water treatment sludge is generated during the treatment of surface water or groundwater for potable use. For a complete legal definition of water treatment sludge, see Title 30, Texas Administrative Code (30 TAC), Section 312.82Exit TCEQ.

  • To apply Class A sewage sludge to the land, you must first notify the TCEQ. Class A sewage sludge has been treated to reduce pathogens and its attractveness to vectors to a greater extent than is achieved in Class B sewage sludge. For a complete legal definition of Class A sewage sludge, see Title 30, Texas Administrative Code (30 TAC), Section 312.82Exit TCEQ, Subsection (a).
