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;

material or energy. The narrative shall include any water addition,
processing rates, equipment, and mass balance or energy balance calculations;

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;

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 subparagraph (1)(B) 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
