The Texas Commission on Environmental Quality (TCEQ) is the governing body for the State of Texas for on-site sewage facilities (OSSF’s). The TCEQ published the latest version of Title 30, chapter 285 effective December 27th, 2012 in document RG-472 dated March of 2013. Title 30, chapter 285 defines the minimum requirements that are required for an OSSF based on the site evaluation and the facility that it will service. Some counties have county orders in place that further restrict the design and permitting of OSSF’s which also must be adhered to.
- Harris County has a county order in place that is more stringent than that of the TCEQ.
- Liberty County
- Montgomery County has a county order which is more stringent than that of the TCEQ.
