Section 311.53 - Wastewater DisposalAny proposed sewage treatment facility in the Lake Lyndon B. Johnson or Lake Marble Falls Water Quality Area will be required to provide secondary treatment facility in accordance with one of the following options:
(1) the treatment facility will provide treatment as specified in Effluent Sets 2 and A in § 309.4 of this title (relating to Table 1, Effluent Standards for Domestic Wastewater Treatment Plants) prior to discharge into on-channel ponds. Such ponds will be designed, constructed, and operated to meet standards established on a case-by-case basis that will assure that any overflows of treated effluent occur only when the volume of effluent to stormwater in the pond is less than or equal to 1:10. For the purposes of this paragraph and calculation, effluent does not include any amount of stormwater runoff, but only the amount of wastewater discharge from the plant. Standards will include, but are not limited to, a minimum pond size requirement based on hydrological studies of the drainage area of the pond and allowable irrigation rates as determined in accordance with § 317.10(c) of this title (relating to Appendix B-Land Disposal of Sewage Effluent); or(2) the treatment facility will provide secondary treatment as specified in §§ 309.1(c)-309.4 of this title (relating to Introduction and Purpose, Rationale for Effluent Sets; Application of Effluent Sets and Table 1, Effluent Standards for Domestic Wastewater Treatment Plants) prior to discharge into storage ponds for land disposal. Storage ponds and land disposal practices will be designed, constructed and operated in accordance with § 317.10(c) of this title (relating to Appendix B--Land Disposal of Sewage Effluent).30 Tex.
