(a) Applicability of standards. These minimum standards shall be considered as minimum requirements within the State of Texas and shall in no way affect the authority of municipalities to enact more stringent regulatory ordinances nor counties to pass an order establishing more stringent regulations governing the use of private sewage facilities in the county as authorized under Texas Water Code §21.084. Proposed county regulations must be approved by the Texas Water Quality Board prior to enactment.
