Off-Site Treatment

You may complete Part II for only the off-site locations that apply to the specific chemical cited in a particular report you can list all off-site locations that apply to all chemicals being reported and include a photostatic copy of Part II with each individual report. List only publicly owned treatment works (POTWs) and off-site treatment or disposal facilities. 

In this section, report only information about treatment of wastestreams at vour facilitv. not about off-site treatment. If you do not perform on-site treatment of wastes containing the chemical being reported, check the Not Applicable (NA) space at the top of Section 7.

On-site treatment in batch reactors using refinery and wood-preserving waste added to soil resulted in highly variable loss of PAHs over a year (Aprill et al. 1990). An extensive study (Ellis et al. 1991) examined a number of design features, and the relative merits of on-site and off-site treatments of a... 

Off-site landfill is not desirable, because it faces more problems associated with off-site transportation. Other off-site treatment and disposal, such as incineration or other waste treatment methods performed off site, are also not attractive, because they are not the on-site permanent... 

Ideally, the site characterization study has defined the vertical and horizontal extent of the contamination. Contoured site maps showing the (three-dimensional) distribution of the contaminants allow identification of areas that require extensive restoration, or may be allowed to be monitored to closure under natural attenuation. Knowledge of how much contamination exists and its location is the important first step in the remediation process. Evaluation of these data will permit consideration of the various remediation remedies available. Where the contaminant is contained within the shallow (<6 m) unsaturated zone and is recalcitrant (not readily biodegradable), excavation for off-site treatment or disposal may be the most expeditious procedure. Alternatively, depending on the contaminant, a variety of in situ procedures, including bioremediation, air sparging, soil vapor extraction, and fixation, may be applicable. 

Any person who transports, or offers for transportation, hazardous waste for off-site treatment, storage, or disposal must prepare a manifest before transporting the waste off-site. The person must designate, on the manifest, one facility which is permitted to handle the waste described on the manifest. A person may also designate one alternate facility that can be... 

In Delaware, KEECO used KB-SEA to treat 2000 yd of sediments contaminated with lead. The total cost of the project was 200,000. The project manager estimated that off-site treatment and disposal of the sediments would have cost 300,000 and that disposal in a hazardous landfill would have cost 750,000 (D202824, p. 1 D20296A, p. 3).

Pursue a modified DFS and off-site treatment on parallel paths until state regulatory authorities indicate whether off-site shipment is viable. 

Ex situ remediation Refers to the treatment of contaminants either by excavating contaminated soils and sediments or pumping contaminated groundwater to the surface for on- or off-site treatment and disposal (compare with in situ remediation). 

Permit conditions will also affect the disposition of waste. For example, in Oregon all waste, with some minor exceptions, must be treated on-site. This significantly inhibits the options for disposal of the wastes off-site. Treatment on-site is limited by the capacity of the metal parts furnace (MPF) and its availability when it is not processing the munitions. Permits at the other locations are not as restrictive as in Oregon, which requires on-site treatment of secondary waste. The detailed differences in operations are discussed in Chapter 3 of the report.

Wastes are mainly divided into two types hazardous and nonhaz-ardous. A proper segregation reduces the volume of hazardous waste by preventing the mixing of hazardous and nonhazardous wastes. The separation of hazardous waste from nonhazardous can significantly reduce the quantity of one kind of waste, which in turn reduces the treatment or disposal cost. Moreover, this waste can be reduced or sent to an onsite or off-site treatment plant for recovery. 

In selecting a particular physical, chemical, and biological method of treatment, the economic feasibility of the method is an important factor as well. The cost of treatment procedure and the amount of the waste to be treated is also a strong factor. Moreover, the on-site and off-site treatments should also be considered in determining the cost of the... 

Excavation in order to remove drums and highly polluted waste. If the most contaminated waste in the landfill body can be identified, excavation may be an efficient remediation technique. Partly corroded drums may be difficult to handle without contaminating the waste material this is for precautions and care. The excavated material may be removed for off-site treatment or may be re-landfilled in landfill sections established with landfill liners, leachate drainage collection, and treatment systems.

The Design Options Working Group recommends to the CO CAC that the CO CAC a thrui its positron that on-site treatment of hydrolysate be conducted at PCAPP and that off-site treatment of hydrolysate be rejected. This decision is based, in part, on review of the financial analysis presented to the CO CAC at the December 8,2006 meeting and review of the recently released Mitretek and Lean-Six-Sigma reports.
