This must include any groundwater modeling data and results as described in § 330.403(e)(2) of this title and consider changes in groundwater flow that are expected to result from construction of the facility;(4) detailed plans and an engineering report describing the proposed groundwater monitoring program to be implemented to meet the requirements of § 330.403 of this title;(5) if the hazardous constituents listed in the table located in 40 Code of Federal Regulations Part 258, Appendix I, and § 330.419 of this title have not been detected in the groundwater at the time of permit application, the owner or operator shall submit sufficient information, supporting data, and analyses to establish a detection monitoring program that meets the requirements of § 330.407 of this title (relating to Detection Monitoring Program for Type I Landfills). This submission must address the following items as specified in § 330.407 of this title: (A) a proposed groundwater monitoring system;(B) background values for each monitoring parameter or constituent listed in § 330.419 of this title, or procedures to calculate such values; and(C) a description of proposed sampling, analysis, and statistical comparison procedures to be utilized in evaluating groundwater monitoring data;(6) if the presence of hazardous constituents listed in § 330.419 of this title has been detected in the groundwater at the time of the permit application, the owner or operator shall submit sufficient information, supporting data, and analyses to establish an assessment monitoring program that meets the requirements of § 330.409 of this title. To demonstrate compliance with § 330.409 of this title, the owner or operator shall address the following items: (A) a description of any special wastes previously handled at the MSW facility;(B) a characterization of the contaminated groundwater, including concentration of assessment constituents as defined in § 330.409 of this title;(C) a list of assessment constituents as defined in § 330.409 of this title for which assessment monitoring will be undertaken in accordance with § 330.405 of this title (relating to Groundwater Sampling and Analysis Requirements) and § 330.409 of this title;(D) detailed plans and an engineering report describing the proposed groundwater monitoring system, in accordance with the requirements of § 330.405 of this title; and(E) a description of proposed sampling, analysis, and statistical comparison procedures to be utilized in evaluating groundwater monitoring data; and(7) if hazardous constituents have been measured in the groundwater that exceed the concentration limits established in § 330.409 of this title, the owner or operator shall submit sufficient information, supporting data, and analyses to establish a corrective action program that meets the requirements of § 330.411 and § 330.413 of this title (relating to Assessment of Corrective Measures and Selection of Remedy). To demonstrate compliance with § 330.411 of this title, the owner or operator shall address, at a minimum, the following: (A) a characterization of the contaminated groundwater, including concentrations of assessment constituents as defined in § 330.409 of this title;(B) the concentration limit for each constituent found in the groundwater;(C) detailed plans and an engineering report describing the corrective action to be taken;(D) a description of how the groundwater monitoring program will demonstrate the adequacy of the corrective action; and(E) a schedule for submittal of the information required in subparagraphs (C) and (D) of this paragraph provided the owner or operator obtains written authorization from the executive director prior to submittal of the complete permit application.(g) Landfill gas management plan. A facility gas management plan shall be prepared to address all of the requirements in Subchapter I of this chapter (relating to Landfill Gas Management).(h) Closure plan. The facility closure plan shall be prepared in accordance with Subchapter K of this chapter (relating to Closure and Post-Closure). For a landfill unit, the closure plan will include a contour map showing the final constructed contour of the entire landfill to include internal drainage and side slopes plus accommodation of surface drainage entering and departing the completed fill area plus areas subject to flooding due to a 100-year frequency flood. Cross-sections shall be provided.(i) Post-closure plan. The facility post-closure care plan shall be prepared in accordance with Subchapter K of this chapter.(j) Cost estimate for closure and post-closure care. The owner or operator shall submit a cost estimate for closure and post-closure care in accordance with Subchapter L of this chapter (relating to Closure, Post-Closure, and Corrective Action Cost Estimates). For an existing facility, the owner or operator shall also submit a copy of the documentation required to demonstrate financial assurance as specified in Chapter 37, Subchapter R of this title (relating to Financial Assurance for Municipal Solid Waste Facilities). For a new facility, a copy of the required documentation shall be submitted 60 days prior to the initial receipt of waste.30 Tex. Admin. Code § 330.63
