Texas Administrative Code › Title 30 - ENVIRONMENTAL QUALITY › Part 1 - TEXAS COMMISSION ON ENVIRONMENTAL QUALITY › Chapter 311 - WATERSHED PROTECTION RULES › Subchapter H - REGULATION OF QUARRIES IN THE JOHN GRAVES SCENIC RIVERWAY › Section 311.77 - Technical Demonstration

Current through Reg. 49, No. 28; July 12, 2024
(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 uplugged
				  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 for Quarries Located Within a
				  Water Quality Protection Area in the John Graves Scenic Riverway and Additional
				  Performance Criteria for Quarries Located Between 200 Feet and 1,500 Feet of a
				  Water Body Located Within a Water Quality Protection Area in the John Graves
				  Scenic Riverway).
(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.
