Waste minimization storage

Requires annual certification by hazardous waste generators who operate onsite TSD facilities that they have a waste minimization program in operation. Further, they must certify that the treatment, storage, or disposal methods minimize threats to human health and environment. 

We must recognize, however, that our abilities may be limited by a lack of other types of data and by the limitations of the rapidly evolving science of risk assessment. In an effort to minimize these limitations, the Office of Solid Waste is investigating the best available risk assessment techniques. These include estimation of the movement of pollutants through soil, air, and water prediction of adverse human health and environmental effects on the basis of available toxicity data and prediction of the effects of simultaneous exposures to numerous toxic substances. OSW is, in addition, actively compiling data relative to the cost, applicability, and effectiveness of currently available waste treatment, storage, and disposal technologies. 

A key theme of this chapter is the reutilization of chemicals via available disposition routes. Any surplus chemicals still remaining at the end of the disposition cycle may re-enter it or be subject to final disposal as solid waste. Exceptions include chemicals that qualify for recycling and recovery (e.g., precious metals, ethylene glycol, anti-ffeeze solutions) or can be classified as Universal waste (see def.) under applicable environmental regulations. These pollution prevention and waste-minimization activities are covered in Chapter 7 ( Pollution Prevention and Waste Minimization ). However, requirements related to waste operations, such as the identification, storage, handling, transportation, treatment and disposal of waste fall outside the scope of the present chapter on chemical disposition. 

EPA regulations that inhibit laboratory and on-site minimization, storage, and treatment of mixed waste. 

At Hanford, for example, an evaporator is used to reduce the volume of waste entering the high-level storage tanks. The standard practice for ten years of evaporator operation was to use filtered river water, which was then sent for wastewater treatment after one use. This year, we made process modifications that allow the reuse of condensate water instead of the filtered river water. The expected dollar savings per year of operation is 3.1 million, and savings in filtered river water not used is 2.1 million gallons (over 8 million liters). We now require the consideration and incorporation of waste minimization features in the design process for all new facilities. 

RCRA also includes the management of nonhazardous wastes, special wastes, industrial wastes, and universal wastes. In 1984, the federal Hazardous and Solid Waste Amendments (HSWA) focused attention on waste minimization, land disposal restrictions, corrective actions for releases, and risks to the environment from underground storage tanks. 

Inherent Safety Minimal storage and transportation of hazardous material Fair. Neutralents are under engineering controls. Liquid effluent is evaporated, and salts are crystalized, placed into drums, and sent to a hazardous waste landfill following TCLP testing. 

Hazardous Waste Consultant (0738-0232). This journal has articles about the newest developments relating to hazardous waste assessment, treatment, storage, and disposal as well as waste minimization technologies. In addition, summaries of federal and state legal cases with a focus on regulatory interpretation and enforcement related to hazardous waste compliance are reported. 

Generators are required to complete biennial reports to the US EPA. These reports, which are due by March 1 of even numbered years, document generator information, describe waste minimization efforts, and show all shipments of hazardous waste shipped off-site to storage, treatment and disposal facilities. Individual states may also have reporting requirements. 

The main objectives of RCRA ate to protect pubHc health and the environment and to conserve natural resources. The act requires EPA to develop and adininistet the following programs soHd waste disposal practices providing acceptable protection levels for pubHc health and the environment transportation, storage, treatment, and disposal of hazardous wastes practices that eliminate or minimize hazards to human health and the environment the use of resource conservation and recovery whenever technically and economically feasible and federal, state, and local programs to achieve these objectives. 

Waste material snch as tank bottoms from crude oil storage tanks constitute a large percentage of refinery solid waste and pose a particularly difficult disposal problem due to the presence of heavy metals. Tank bottoms are comprised of heavy hydrocarbons, solids, water, rust, and scale. Minimization of tank bottoms is carried ont most cost-effectively through careful separation of the oil and water remaining in the tank bottom. Filters and centrifuges can also be used to recover the oil for recycling.
