TCEQ grants Clear Utilities wastewater permit amid disputes over modeling and dissolved oxygen
Summary
The commission adopted the ALJ’s order and issued a wastewater permit to Clear Utilities LLC (WQ0016273001) after protestants argued TCEQ used default modeling and should apply site-specific CSTR modeling to address dissolved oxygen and sediment oxygen demand concerns.
The Texas Commission on Environmental Quality voted to issue a wastewater permit to Clear Utilities LLC, adopting the administrative law judge’s proposed order with the Executive Director’s recommendation.
Curran Walker, counsel for the applicant, urged adoption of the PFD and reserved time for rebuttal. Protestants, led by Stephanie Albright on behalf of Ellis County, argued that the draft permit’s modeling fails to account for site‑specific conditions in the receiving waters and therefore underestimates impacts on dissolved oxygen. Albright said TCEQ used default hydraulic coefficients and the QualTex model rather than continuous stirred tank reactor (CSTR) modeling for a receiving pond, and that default values understated sediment oxygen demand in the site’s silty/muddy conditions.
Vic McWhirter, representing Citizens for Responsible County Development and landowner Glenda Williams, pressed for a clearer description of the discharge route, contending TCEQ staff supplemented the application’s narrative with new tributary designations found via online research rather than requiring an amended application that explicitly described all segments of the route.
Executive Director counsel Michael Parr and Office of Public Interest Counsel attorney Eli Martinez both told commissioners the ED’s reviews and the ALJ’s PFD demonstrate the applicant met its burden for the referred issues, including water quality, groundwater protections, buffer and location standards, and regionalization need. After rebuttal from applicant counsel emphasizing the PFD’s analysis, commissioners voted to adopt the ALJ’s proposed order and issue the draft permit as recommended.
The record reflects competing technical positions: protestants argued site‑specific modeling and sediment oxygen demand inputs were essential to protect dissolved oxygen standards, while the ED and ALJ relied on TCEQ modeling procedures and default inputs as meeting regulatory requirements. The commission’s action issues the permit; the transcript does not record any additional on‑site studies ordered at this session.
