| (a) The Technical Demonstration must include, at a
minimum:
(1) a time schedule for the proposed quarry from initiation
to termination of operations, including reclamation;
(2) a detailed description of the type of quarrying
to be conducted, including the processes/methods employed (e.g., pit
mining where blasting is employed);
(3) a geological description of the quarry area, including
a detailed description of the material deposit: type, geographical
extent, depth, and volume; and a description of the general area geology;
(4) identification and a detailed description of any
other operations on site, including raw-material processing and/or
secondary products (e.g., cement) processing;
(5) identification and a detailed description of type,
character, and volume of wastewater and storm water generated on site;
(6) a topographic map, at a scale appropriate to represent
the quarry operation and all of the following within the boundaries
of the quarry:
(A) waterbodies;
(B) existing and proposed roads including quarry access
roads;
(C) existing and proposed railroads;
(D) the 100-year floodplain boundaries, if applicable;
(E) structures (e.g., office buildings);
(F) the location of all known wells including, but
not limited to, water wells, oil wells, and unplugged and abandoned
wells;
(G) active, post, and reclaimed quarrying areas;
(H) buffer areas;
(I) raw material, intermediate material, final product,
waste product, byproduct, and/or ancillary material storage and processing
areas;
(J) chemical and fuel storage areas;
(K) vehicle/equipment maintenance, cleaning, and fueling
areas;
(L) vehicle/equipment loading and unloading areas;
(M) baghouses and other air treatment units exposed
to precipitation; and
(N) waste disposal areas;
(7) a Surface Water Drainage and Water Accumulation
Plan. The Surface Water Drainage and Water Accumulation Plan must
be designed to prevent damage to fish, wildlife, and fish/wildlife
habitat from erosion, siltation, and runoff from quarry operations.
The Surface Water Drainage and Water Accumulation Plan must, at a
minimum:
(A) describe the use and monitoring of structural controls
and best management practices as identified in paragraph (8) of this
subsection designed to control erosion, siltation, and runoff; and
(B) provide a topographic map, at a scale appropriate
to represent the quarry operation and all of the following within
the boundaries of the quarry:
(i) the location of each process wastewater and/or
storm water outfall;
(ii) an outline of the drainage area that contributes
storm water to each outfall;
(iii) treatment, detention, and water storage tanks
and ponds;
(iv) structural controls for managing storm water and/or
process wastewater; and
(v) physical features of the site that would influence
storm water runoff or contribute a dry weather flow; and
(8) a Best Available Technology Evaluation. The Best
Available Technology Evaluation assists staff in reviewing and determining
the best available technology designed to control erosion, siltation,
and runoff from the quarry to minimize disturbance and adverse effects
to fish, wildlife, and related environmental resources. Where practical,
the Best Available Technology Evaluation must assist staff in reviewing
and determining best available technology designed to enhance fish,
wildlife, and related environmental resources.
(A) The Best Available Technology Evaluation must assess
the use of structural controls and best management practices.
(B) The Best Available Technology Evaluation must evaluate
performance criteria outlined in §311.79 and §311.80 of
this title (relating to Performance Criteria and Additional Performance
Criteria for Quarries Located Between 200 Feet and 1,500 Feet of a
Water Body).
(C) Structural control design and construction must
be certified by a licensed Texas professional engineer. Design and
construction plans/specifications must be maintained on site and made
available at the request of the executive director; and
(9) a procedure and schedule for reviewing the Technical
Demonstration for consistency with quarry operations and site conditions
and effectiveness in controlling erosion, siltation, and runoff.
(b) Certification of the Technical Demonstration must
be provided, within the appropriate area or discipline, by a licensed
Texas professional engineer or a licensed Texas professional geoscientist.
Components of the Technical Demonstration may be independently certified,
as appropriate.
