This description shall also contain an estimate of the daily quantity of material to be processed at the facility along with a description of the proposed process of screening for hazardous materials; (ii) the methods of excavating the buried waste materials. The owner or operator shall indicate how the material will be handled, how long it will remain in the area, what equipment will be used, how the material will be moved from the excavation area, how the excavation area will be held to a minimum, the maximum side slopes in buried waste, and the maximum excavation area at any one time. The owner or operator shall provide the sequence of excavation; (iii) the processes used to recover reusable or recyclable material or energy. The narrative shall include any water addition, processing rates, equipment, and mass balance or energy balance calculations; (iv) how any process water will be handled and disposed of if a wet mining process is to be used; (v) a complete narrative on product distribution to include items such as disposition of material or energy recovered and probable use of soils on site and off site; and (vi) a process diagram that depicts the general process; (C) a description of liner system used for excavated waste storage, processing, and screening areas to control seepage and runoff. The liner shall be covered with a material designed to withstand normal traffic from the processing operations; and (D) a description of how waste excavation activities will comply with the minimum design and operation requirements of: (i) §330.149 (relating to Odor Management Plan); (ii) §330.151 (relating to Disease Vector Control); (iii) §330.165 (relating to Landfill Cover); and (iv) §330.167 (relating to Ponded Water). (8) Compost units. The owner or operator shall provide: (A) for mechanical composting systems, a detailed engineering description of the system and the manufacturer's performance data; (B) facility layout, including calculations for area requirements; (C) a description of the movement of the material as it leaves the tipping area indicating how the material is incorporated into the composting process and what handling techniques are used all the way through to the post-processing area. The narrative must include: (i) processing rates; (ii) equipment; (iii) mass balance calculations; (iv) use of bulking agents, moisture control, or feed amendments; (v) process monitoring methods; (vi) temperature range and resident time; (vii) storage of compost for curing after the primary composting operation; and (viii) provision for additional drying and screening; (D) a narrative on the post-processing process, including post-processing times, identification and segregation of product, storage of product, and quality assurance and quality control; and (E) a narrative on product distribution including items such as end-product quantities, anticipated final grades, packaging, labeling, loading, marketing, distribution, tracking, and delivery of composted material. (9) Type VI waste processing demonstration facilities. (A) The facility size shall be limited to a liquid waste processing rate no greater than 10,000 gallons per day. (B) The facility design and operation shall be coordinated with a consultant connected with an accredited college or university or with a consultant that has demonstrated the ability to carry out scientific experiments for demonstrating new and unproven waste handling methods and submitted to the executive director. The owner or operator shall submit to the executive director an annual and final status report to document the viability of the method being demonstrated. The report, at a minimum, must document the effluent standards and solid waste standards achieved. (C) The owner or operator may request a variance. (i) In specific cases, the executive director may approve a variance from the requirements of this chapter if the variance is not contrary to safeguarding the health, welfare, and physical property of the people and to protecting the environment. A variance may not be approved concerning the procedural requirements of this chapter. (ii) A request for a variance must be submitted in writing to the executive director. The request may be made in an application for a registration. Any approval of a variance must be in writing from the executive director. (e) Geology report. This portion of the application applies to owners or operators of MSW landfills, compost units, and if otherwise requested by the executive director. The geology report shall be prepared and signed by a qualified groundwater scientist. Previously prepared documents may be submitted but must be supplemented as necessary to provide the requested information. Sources and references for information must be provided. The geology report must contain the following information: (1) a description of the regional geology of the area that includes: (A) a geologic map of the region with text describing the stratigraphy and lithology of the map units. An appropriate section of a published map series such as the Geologic Atlas of Texas prepared by the Bureau of Economic Geology is acceptable; and (B) a description of the generalized stratigraphic column in the facility area from the base of the lowermost aquifer capable of providing usable groundwater, or from a depth of 1,000 feet, whichever is less, to the land surface. The geologic age, lithology, variations in lithology, thickness, depth, geometry, hydraulic conductivity, and depositional history of each geologic unit should be described based upon available geologic information. Regional stratigraphic cross-sections should be provided; (2) a description of the geologic processes active in the vicinity of the facility that includes an identification of any faults and subsidence in the area of the facility. The information about faulting and subsidence shall include at least that required in §330.555(b) and §330.559 of this title (relating to Fault Areas and Unstable Areas); (3) a description of the regional aquifers in the vicinity of the facility based upon published and open-file sources that provides: (A) aquifer names and their association with geologic units described in paragraph (2) of this subsection; (B) the composition of the aquifer(s); (C) the hydraulic properties of the aquifer(s); (D) information on whether the aquifers are under water table or artesian conditions; (E) information on whether the aquifers are hydraulically connected; (F) a regional water-table contour map or potentiometric surface map for each aquifer, if available; (G) an estimate of the rate of groundwater flow; (H) typical values or a range of values for total dissolved solids content of groundwater from the aquifers; (I) identification of areas of recharge to the aquifers within five miles of the site; and (J) the present use of groundwater withdrawn from aquifers in the vicinity of the facility. The identification, location, and aquifer of all water wells within one mile of the property boundaries of the facility shall be provided; Cont'd... |
