In the hazardous waste environment a level of proteetion should be speeified for eaeh job task, as appropriate. For nonhazardous waste jobs the levels may not be reeognized or aeeepted. In this seetion we will first diseuss PPE for hazardous waste aetivities and then diseuss PPE in general. 

Are all emissions and discharges documented in an inventory, for example, process effluent domestic wastewater, cooling water, stack emissions, hazardous wastes, nonhazardous wastes Provide a schedule of emissions. Identify the risk category. 

RCRA was passed to manage nonhazardous and hazardous wastes and underground storage tanks, with an emphasis placed on the recovery of reusable materials as an alternative to their disposal. This act introduced the concept of the separate management of hazardous and nonhazardous wastes, and defined procedures to identify whether a waste is hazardous or nonhazardous. A waste exhibits the characteristic of toxicity, classified as a hazardous material, if the concentration of any of 39 selected analytes in the Toxicity Characteristic Leaching Procedure (TCLP) extract exceed regulatory action levels. 

Characteristic wastes that are decharacterized subsequent to the point of generation (i.e., they become nonhazardous) are handled differently. Once a waste is decharacterized and has met its full LDR treatment standards, it can go to an RCRA nonhazardous waste facility. These LDR notifications and certifications are sent to the U.S. EPA Region or authorized state rather than to the receiving facility. This is intended to protect facilities from the burden of hazardous waste paperwork. 

There are eight exemptions from the mixture rule. The first exemption from the mixture rule applies to mixtures of characteristic wastes and specific mining wastes excluded under RCRA. This narrow exemption allows certain mixtures to qualify as nonhazardous wastes, even if the mixtures exhibit one or more hazardous waste characteristics. The mining waste exclusion is explained in more detail in a U.S. EPA module.9... 

The number of industrial-waste injection wells more than doubled between 1967 and 1986.3 In 1986, Class I injection wells were concentrated in two states, Texas (112 wells) and Louisiana (70 wells), which between them had a total of 69% of all wells (263 wells). Growth from 1984 to 1986 was concentrated in Texas, with a 38% increase from 81 to 112 wells. The only other states to show a significant increase from 1984 to 1986 were Indiana (13 proposed wells) and California (7 proposed wells). Nine states had had industrial-waste injection wells in the past but did not have any permitted Class I wells in 1986 (Alabama, Colorado, Iowa, Mississippi, Nevada, North Carolina, Pennsylvania, Tennessee, and Wyoming). One state (Washington) had a Class I well in 1986, but no record of industrial wastewater injection before that year. The total number of industrial-waste injection wells increased to 300 at the end of the 1990s and beginning of this century, approximately 100 Class I hazardous waste injection wells and about 200 Class I wells that hold nonhazardous waste.1-18...

The RCRA controls the disposal of solid waste and requires that all wastes destined for land disposal be evaluated for their potential hazard to the environment. Solid waste includes liquids, solids, and containerized gases and is divided into nonhazardous waste and hazardous waste. The various amendments are aimed at preventing the disposal problems that lead to a need for the Comprehensive Environmental Response Compensation and Liability Act (CERCLA), or Superfund, as it is known. 

There are five specific listed hazardous wastes (K list) generated in refineries, K048 to K052. Additional listed wastes, those from nonspecific sources (F list) and those from the commercial chemical product lists (P and U), may also be generated at refineries. Because of the mixture and derived-from rules, special care must be taken to ensure that hazardous wastes do not contaminate nonhazardous waste. Under the mixture rule, adding one drop of hazardous waste in a container of nonhazardous materials makes the entire container contents a hazardous waste. 

Pollution prevention is, simply, reduction or elimination of discharges or emissions to the environment. The limits of pollutants emitted to the atmosphere, the land, and water are defined by various pieces of legislation that have been put into place over the past four decades (Chapter 5) (Speight, 1996 Woodside, 1999). This includes all pollutants, such as hazardous and nonhazardous wastes and regulated and unregulated chemicals from all sources. 

Fires result in impacts on the environment air pollution, firefighting water runoff, and hazardous and nonhazardous waste. 

Hazardous and Nonhazardous Waste—after a fire is extinguished, the clean-up begins. There may be both hazardous and nonhazardous wastes that need disposal. Asbestos wastes may be an issue in older facilities. 

Solids that enter the refinery s wastewater treatment system automatically are classified as hazardous waste. Therefore, refiners can lower the volume of hazardous waste generated by keeping nonhazardous waste out of the treatment system ... 

The cost-effectiveness of the Chemfix process depends partly on whether treated material may be disposed of as nonhazardous waste. If waste remains hazardous after treatment, it must be disposed of as a hazardous waste at a specified facility this causes a significant increase in the total cost of Chemfix treatment (D130847, p. 9). 

Treatment produces lower volumes requiring disposal, and the solids filter cake formed may allow for disposal as nonhazardous waste. 

The vendor claims the enzyme solution is produced through a biological process and is nonhazardous. Enzyme solution is reused until the end of the project, when it can be injected into a nonhazardous waste disposal well or processed through a wastewater treatment facility. All information is from the vendor and has not been independently verified. 

The hazardous component of the treated wastes is eliminated treated wastes contaminated with metals may be disposed of as nonhazardous wastes, and mixed wastes may be disposed of as radioactive wastes, reducing disposal costs and liability concerns. 

Pretreatment is required for HTV processing. Drying and size reduction of wastes are required. Additives such as glass formers may be required. Processing of nonhazardous wastes may not be economically feasible. Treatment of radioactive wastes will produce a radioactive glass that requires special handing or treatment.
