Current through September 17, 2024

Section 132-14-006 - Beneficial reuse of waste tires

Beneficial reuse shall mean waste tires used for agricultural purposes as defined in Chapter 1; as fish habitat; as blowout stabilization; tire mats for bank stabilization; or burned for energy recovery.

006.01 The following are standards and criteria for specific approved beneficial reuse of waste tires:

006.01A Stream bank, lake bank and culvert outlet mats using whole waste tire mats, constructed as follows:

006.01A1 The whole waste tires shall be placed in a single layer, with waste tires bonded together with a non-corrodible connector;

006.01A2 The whole waste tires shall all be drilled or punctured with at least one ( 1.0 ) inch diameter hole(s) to allow outflow of air to prevent flotation. The whole waste tires shall be oriented in the mat such that the hole(s) prevent flotation during submerged conditions;

006.01A3 The bonded whole waste tire mat shall be anchored with cable of at least 0.5 inches in diameter;

006.01A4 The cables shall then be fastened to buried anchors made of treated timbers or concrete, at least every 50 feet along the top and sides and at the rate of one (1) anchor per one thousand square feet (1,000 ft²) of the waste tire mat face and at the rate of one (1) anchor per one hundred fifty square feet (150 ft²) of waste tire mat resting on the bottom of the stream, lake or culvert channel;

006.01A5 The whole waste tire mat should extend four (4) to six (6) feet into the stream channel, lake bottom or culvert channel bottom and shall be vertically entrenched at least one (1) tire width in the bottoms to avoid undercutting;

006.01A6 The outermost row in the flow bottom(s) shall be filled with rocks or concrete debris sized to remain in place when subjected to the velocities of the design storm;

006.01A7 Vegetation shall be planted in and around the whole waste tire mat; rows within the waste tire mat that are too wet for vegetation establishment shall be filled with rocks or concrete debris sized to remain in place under the velocities of the design storm;

006.01A8 Each whole waste tire mat shall be shown to be stable when subjected to the velocity of the design flow(s) by standard hydraulic equations, which utilize verifiable hydraulic constants.

006.01B Stream bank, lake bank and culvert outlet mats using processed waste tire mats, which meet the following criteria:

006.01B1 Processed waste tire mats are not appropriate in flowing water with velocity greater than five (5) feet per second unless they are shown to be stable under velocities of flow greater than five (5) feet per second. All flow velocities shall be determined by applicable standard hydraulic equations utilizing verifiable hydraulic constants;

006.01B2 Processed waste tire mats shall be placed in a single layer and connected with non-corrodible connectors;

006.01B3 The processed waste tire mat shall be anchored to the bank along the top, toe and upstream and downstream ends of the waste tire mat;

006.01B4 The processed waste tire mat should extend four to six feet out into the channel bottom.

006.01C Blowout Stabilization. Waste tires used for blowout stabilization must be designed using the following criteria:

006.01C1 The stabilized area of the blowout must have one single layer of relatively uniform thickness ranging from a passenger tire to a truck tire. The waste tires must be arranged in a random pattern that does not allow wind to find a straight-line path through the tires. Waste tires shall not be placed inside other waste tires and tires with rims, cut tires or inner tubes shall not be used;

006.01C2 Mulching and seeding is required and may be completed prior to or after the placement of waste tires. An appropriate seed mix and seed rate shall be drilled or broadcast over the site to establish vegetative growth;

006.01C3 The edges of the blowout must be sloped to a ratio of 2:1 (horizontal to vertical) or flatter;

006.01C4 The landowner must consult with the Nebraska Game and Parks Commission (NGPC) regarding possible populations of threatened or endangered species in the area and obtain consent from NGPC before the project begins.

006.01C5 As of January 1, 2011, tires may not be placed into blowouts that are larger than 1/2 (one-half) acre in area.

006.01D The use of waste tires for fish habitat must be in accordance with the requirements of the Nebraska Game and Parks Commission and the U.S. Army Corps of Engineers.
