Texas Commission on Environmental Quality NOTICE OF HEARING 183 258 Liberty Hill LLC SOAH Docket No. 582-26-24418 TCEQ Docket No. 2026-0412-MWD TPDES Permit No. WQ0016517001 APPLICATION. 183 258 Liberty Hill LLC, P.O. Box 200546, Austin, Texas 78720, has applied to the Texas Commission on Environmental Quality (TCEQ) for new Texas Pollutant Discharge Elimination System (TPDES) Permit No. WQ0016517001, to authorize the discharge of treated domestic wastewater at a daily average flow not to exceed 500,000 gallons per day. The facility will be located approximately 0.38 miles northwest of the intersection of County Road 258 and U.S. Highway 183, in Williamson County, Texas 78642. The treated effluent will be discharged via pipe to an unnamed tributary, thence to South Fork San Gabriel River in Segment No. 1250 of the Brazos River Basin. The unclassified receiving water use is limited aquatic life use for the unnamed tributary. The designated uses for Segment No. 1250 are primary contact recreation, public water supply, aquifer protection, and high aquatic life use. In accordance with 30 Texas Administrative Code §307.5 and the Procedures to Implement the Texas Surface Water Quality Standards (June 2010), an antidegradation review of the receiving waters was performed. A Tier 1 antidegradation review has preliminarily determined that existing water quality uses will not be impaired by this permit action. Numerical and narrative criteria to protect existing uses will be maintained. This review has preliminarily determined that no water bodies with exceptional, high, or intermediate aquatic life uses are present within the stream reach assessed; therefore, no Tier 2 degradation determination is required. No significant degradation of water quality is expected in water bodies with exceptional, high, or intermediate aquatic life uses downstream, and existing uses will be maintained and protected. The preliminary determination can be reexamined and may be modified if new information is received. This link to an electronic map of the site or facility's general location is provided as a public courtesy and is not part of the application or notice. For the exact location, refer to the application. https://gisweb.tceq.texas.gov/LocationMapper/?marker=-97.87595,30.66809&level=18 The TCEQ Executive Director has completed the technical review of the application and prepared a draft permit. The draft permit, if approved, would establish the conditions under which the facility must operate. The Executive Director has made a preliminary decision that this permit, if issued, meets all statutory and regulatory requirements. The permit application, Executive Director's preliminary decision, and draft permit are available for viewing and copying at Liberty Hill City Hall, 926 Main Street, Liberty Hill, Texas .
