HB 5549 revises the regulation and planning of on-site sewage disposal systems under Chapters 366 and 367, Health and Safety Code, and Section 5.701, Water Code. The bill updates the statutory purpose of the on-site sewage disposal system program to include system pumping, revises definitions related to nuisances and property ownership, clarifies TCEQ and authorized-agent authority, and gives TCEQ default responsibility for permitting systems that produce more than 1,500 gallons per day unless that authority is specifically delegated to a qualified authorized agent.
The bill also modifies maintenance-contract requirements. It removes the performance-bond requirement, preserves the ability of certain single-family homeowners to maintain their own systems directly, and requires owner-maintained surface disposal systems to include electronic monitoring and alarm equipment. If an owner in a county with a population of at least 40,000 violates applicable requirements, the owner must correct the violation or enter into a maintenance contract; repeated violations within three years require a maintenance contract. The bill increases the maximum administrative penalty for certain violations from $100 to $500 and adds specific disinfection duties for maintenance contracts involving surface spray disposal systems.
The Committee Substitute further expands licensing or registration requirements to persons who construct, install, alter, extend, service, maintain, pump, repair, or access an on-site sewage disposal system or its components. It increases the fee collected for each on-site wastewater treatment permit application from $10 to $30, directs the fee to the entity performing the permitting function, and allows certain fees to be used through the water resource management account. The bill repeals several existing provisions in Chapter 366, Health and Safety Code, and takes effect September 1, 2025.
The originally filed HB 5549 and the Committee Substitute are largely similar in structure and purpose. Both versions revise Chapter 366, Health and Safety Code, to update on-site sewage disposal system regulation, expand TCEQ and authorized-agent oversight, shift default permitting authority for systems producing more than 1,500 gallons per day to TCEQ unless delegated, require approval of any authorized-agent order or resolution amendments, remove the performance-bond requirement tied to certain maintenance contracts, increase the on-site wastewater treatment permit application fee from $10 to $30, and raise the maximum administrative penalty for certain owner violations from $100 to $500.
The most notable difference is that the filed version amended Section 366.012(a), Health and Safety Code, to remove two existing county-specific provisions allowing aerobic drip emitter systems on certain small subdivided or platted lots. Those provisions applied to narrowly bracketed counties based on population and geography. The Committee Substitute does not include that amendment to Section 366.012(a); instead, it amends only Section 366.012(b), which concerns TCEQ rules defining good management practices and procedures for construction and operation of on-site sewage disposal systems.
The Committee Substitute also adds a new substantive requirement for maintenance contracts involving surface spray disposal systems. Unlike the filed version, it requires those contracts to provide for disinfection and specifies duties for maintenance providers during routine visits, including inspecting the disinfection device, checking bleach or tablet levels, and, if ultraviolet light is used, cleaning the bulb sleeve and checking bulb expiration dates. The Committee Substitute also adds language requiring an owner-maintained surface disposal system to be equipped with an electronic monitoring and alarm system.
The caption changed as well. The filed version described the bill as authorizing and increasing a criminal penalty, while the Committee Substitute describes it as authorizing and increasing an administrative penalty. That change better reflects the operative penalty provisions in the Committee Substitute, which concern administrative penalties rather than creating or increasing a criminal offense.
