When moving and/or storing waste containing hazardous components, precautions and/or special handling methods may be used to minimize contamination, loss, and/or spread of hazardous material. Often such precautions and/or special handling methods increase the cost of remediation or transport of these materials. Furthermore, geographic and infrastructure limitations of the property and locality where waste containing hazardous components reside may present additional challenges for remediation. Therefore, there remains a need for improved processes and/or methods for moving or storing waste containing hazardous components.
In some embodiments, the present disclosure relates to transportation of hazardous waste and/or waste classified under the Toxic Substances Control Act (TSCA). For example, in certain embodiments, waste containing polychlorinated biphenyls (PCBs) may be transported.
In some embodiments, the present disclosure utilizes one or more transport barges to move waste over a body of water; stationary barges, such as a spudded landing barge (also known as a spud barge); shipping containers including, but not limited to, intermodal shipping containers (e.g., fully enclosed rectangular containers); trailer chassis; and/or vehicles, including but not limited to trucks such as a semi-tractor, to move the shipping containers over one or more terrestrial locations, and/or onload or offload the shipping containers to one or more of the barges. In certain embodiments, the waste is moved from one terrestrial site to another terrestrial site over a body of water.
In other aspects, the present disclosure relates to the transportation of hazardous waste and/or waste classified under the Toxic Substances Control Act (TSCA) while not using a bulkhead crane, overhead crane, or other large crane.
In some embodiments, the disclosed methods may use an intermodal pin chassis to haul placarded containers and/or to load a transport barge using a semi-tractor.
In some embodiments, the method for transportation of hazardous waste and/or waste classified under TSCA may comprise the acts of: translocating at least one intermodal trailer chassis from a primary terrestrial site to a first stationary barge, wherein said trailer chassis is carrying an intermodal shipping container containing the waste material, and wherein the first stationary barge is adapted to rise and fall with changes to the water level; moving the intermodal trailer chassis carrying the intermodal shipping container from the first stationary barge to a transport barge adapted to traverse the body of water; traversing the body of water with the transport barge; and offloading the at least one intermodal trailer chassis carrying the intermodal shipping container to a secondary terrestrial site via a second stationary barge.
Additional embodiments of the disclosure, as well as features and advantages thereof, will be apparent from the descriptions herein.
For the purposes of promoting an understanding of the principles of the present disclosure, reference will now be made to certain embodiments and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the disclosure is thereby intended, such alterations and further modifications, and such further applications of the principles of the disclosure as described herein being contemplated as would normally occur to one skilled in the art to which the disclosure relates. Additionally, in the detailed description below, numerous alternatives are given for various features. It will be understood that each such disclosed alternative, or combinations of such alternatives, can be combined with the more generalized features discussed in the Summary above, or set forth in the embodiments described below to provide additional disclosed embodiments herein.
In some embodiments, the present disclosure relates to transportation of hazardous waste and/or waste classified under the Toxic Substances Control Act (TSCA). For example, in certain preferred embodiments, waste containing polychlorinated biphenyls (PCBs) may be transported. Title 40 of the United States Code, “Protection of Environment”, includes codified laws regarding Polychlorinated biphenyls including Part 761, which is hereby incorporated by reference in its entirety. Furthermore, Part 261 relates to Identification and Listing of Hazardous Waste and is also incorporated herein by reference in its entirety. Additionally, the Environmental Protection Agency (EPA) has published certain guidance regarding revitalization and remediation for PCB-containing waste. For example, the EPA has published “Polychlorinated Biphenyl (PCB) Site Revitalization Guidance Under the Toxic Substances Control Act (TSCA)” in November 2005, which is hereby incorporated herein by reference in its entirety (Available at https://www.epa.gov/sites/production/files/2015-08/documents/pcb-guid3-06.pdf). For example, waste containing greater than 50 parts per million (ppm) PCD may be regulated under TSCA. Waste may also be classified as hazardous, but not regulated under TSCA, sometimes referred to as “Non-TSCA” waste when the waste comprises less than 50 milligrams per kilogram (mg/kg) PCB. In one embodiment of the present disclosure, sampling of waste material may be performed using one sample per 200 cubic yards (CY) of waste to one sample per 2,000 CY of waste. In other embodiments, sampling can be performed using one sample per 300 CY of waste, one sample per 400 CY of waste, one sample per 500 CY of waste, one sample per 600 CY of waste, one sample per 750 CY of waste, one sample per 1000 CY of waste, one sample per 1250 CY of waste, one sample per 1500 CY of waste, and/or one sample per 1750 CY of waste.
In some embodiments, the present disclosure utilizes one or more barges, including stationary and mobile barges, to move waste over a body of water; shipping containers, including, but not limited to, intermodal (IM) shipping containers; trailer chassis; and/or vehicles, such as trucks or semi-tractors. In certain embodiments, the waste is moved from one terrestrial site to another terrestrial site over a body of water on a mobile barge. In certain embodiments, one or more stationary barges may be utilized to facilitate loading of one or more mobile barges. For example, in one embodiment, a spudded barge is used as a stationary barge to facilitate loading of a mobile barge. In some embodiments, one or more ramps, docks, or barges such as a spudded barge may be used to facilitate loading and/or staging of materials for placement on a mobile barge. A stationary barge, as referred to herein, may also be referred to as a “roll-on/roll-off landing barge.” When used, a ramp may have for example, but is not limited to having, dimensions of 60 feet in length and 53 feet in width. In some embodiments, when used, a ramp connecting a terrestrial site to a stationary barge may be able to account for any change in tide and/or vertical positioning of the stationary barge.
In certain preferred embodiments, the shipping containers used may have a width of 8 feet; a height of 6 feet, 6 feet 9 inches, 8 feet, 8 feet 6 inches, 9 feet 6 inches, or 4 feet 3 inches; and/or a length of 20 feet, 40 feet, 48 feet, or 53 feet. In some embodiments, the shipping containers may comprise a volume of 1,172 cubic feet (ft3)(33.2 m3), 2,389 ft3 (67.6 m3), 3,264 ft3 (92.4 m3), 3,604 ft3 (102.1 m3), 1,520 ft3 (43 m3), or 680 ft3 (19.3 m3). In some embodiments, a shipping container may hold approximately 22.5 tons of material. In some embodiments, a shipping container is placarded, or covered, when used or transported. Other containment precautions, such as lining a shipping container may also be utilized in certain embodiments of the present disclosure. For example, plastic sheets may be used to line a shipping container, and/or a resin or other polymer may be sprayed into or on the shipping container to line the container in some embodiments.
In other aspects, the present disclosure relates to the transportation of hazardous waste and/or waste classified under the Toxic Substances Control Act while not using a bulkhead crane, overhead crane, or other large crane. Cranes can be costly to erect, operate, maintain, and may require other infrastructure that may not be available at a remediation site, dock, or other location where a barge may be loaded. Therefore, in some embodiments, a trailer chassis with a shipping container may be utilized to load and/or unload a barge with waste to be remediated. For example, in some embodiments, methods disclosed herein may use an intermodal pin chassis to haul placarded containers and/or to load a transport barge using a semi-tractor.
In some embodiments, the method for transportation of hazardous waste and/or waste classified under TSCA may comprise the acts of: translocating at least one intermodal trailer chassis from a primary terrestrial site to a first stationary barge, wherein said trailer chassis is carrying an intermodal shipping container containing the waste material, and wherein the first stationary barge is adapted to rise and fall with changes to the water level; moving the intermodal trailer chassis carrying the intermodal shipping container from the first stationary barge to a mobile barge adapted to traverse the body of water; traversing the body of water with the mobile barge; and offloading the at least one intermodal trailer chassis carrying the intermodal shipping container to a secondary terrestrial site via a second stationary barge.
In one embodiment, a batch of 250 tons may be transported in 12 intermodal containers on a barge, each intermodal container comprising a capacity of 22.5 tons each. In another embodiment, 24 intermodal containers may be transported on a mobile barge. In still other embodiments, 36 or 48 intermodal trailers may be transported on a mobile barge. In certain embodiments, the transportation cycle may comprise the acts of a tug arriving with empty intermodal containers on chassis on the deck of a mobile barge; offloading the empty containers, for example by use of a semi-tractor; loading intermodal containers with waste onto the deck of a mobile barge, for example by use of a semi-tractor; and/or the tug and mobile barge departing.
traversing a body of water with the mobile barge; and offloading the intermodal transportation container with hazardous waste on the trailer chassis to a terrestrial site.
