About this selection
These pages come from the 688-page TCEQ production for the Southwest wastewater plant. Page labels below identify the original production; selected source images and existing redactions are preserved.
Reading context and source notes
The selection includes 2023 water-quality and modeling memoranda, a 2021–2023 biomonitoring-history table and December 2023 memo, March 2024 worksheets, the initialed May 14, 2025 revised modeling memo, and May 15–23 email correspondence.
The May 14 memo supersedes the November 13, 2023 memo; the April–October ammonia figure changes from 19 to 29 lbs/day. The May 15 email says modeling was rerun after applicant comments; the May 23 reply says there were no further questions. Native revised-permit attachment identity remains unestablished.
Major/minor and outfall classifications are administrative worksheets; “contaminated” is expressly used for billing and PARIS. These labels and historical test tables are not independent findings of present compliance. The EPA checklist marks review as required, not approved.
The source order is 294–295, 300, 299, 296–298, 275–286, 292–293, 288–289. Original initials, signatures and wording remain; existing email blackouts and one repeated address are masked. The alternate scan at 290–291 remains outside this selection.

The application, models, sampling-waiver correspondence, maps and photographs explain what was submitted and reviewed. Compare them with the issued terms and separately dated monitoring records. An application-sampling waiver is not a waiver of routine permit monitoring; models, applicant estimates and source captions do not establish measured performance or current conditions.
