Under Part 1 of EPA 90, an IPC system eontrols emissions to air, land and water for the most polluting industrial and similar proeesses. All operators of preseribed proeesses, e.g. fuel and power, minerals, waste disposal and ehemieal, require prior authorization. They are required to use BATNEEC, the Best Available Teehnology Not Entailing Exeessive Cost ... 

Under Part I of the act an IPC system controls emissions to air, land or water for the most polluting industrial and similar processes. IPC is limited to prescribed processes (e.g. chemical, fuel and power, waste disposal, minerals etc.) by prior authorization. Authorization is based on the requirement for owners/controllers to prevent release of prescribed substances or, where this is not practicable, to reduce the release to a minimum. Any residual release must be rendered harmless. To achieve these aims, operators must use the best practicable means not entailing excessive cost (BATNEEC).

The major portion of gaseous carbon compounds comes into the atmosphere from natural sources as a result of biological processes and forest fires, etc. A certain portion is produced directly in the atmosphere during the reactions of primary pollutants. Industry and transport are responsible for very considerable contributions to anthropogenic sources of emissions of carbon compounds, which are particularly concentrated in the atmosphere above and around city agglomerations. 

In contrast to the above, considerably higher concentrations of these substances are found—yearly average and for short periods—in polluted industrial and urban areas (Table 7.2). 

Heavily polluted, industrial and waste waters usually undergo a thorough decomposition by modem wet-digestion methods, UV irradiation in the presence of oxidants or some special operations, such as extraction or column separation, enabling to isolate either too resistant matrix constituent(s) or the analyte itself. In electroanalytical determinations of heavy metals, all these approaches have already been successfully applied (see, e.g., references (30-33) and (16, 25) in Table 5.1). 

The Clean Water Act (1972) requires discharge limits to be set on industrial and municipal wastewater, and these analyses are outlined in the National Pollution Discharge Elimination System for the 600 Series Methods. Method 624 covers the analysis of purgeable organic compounds Method 625 covers the analysis of 81 bases, neutrals, and acids Method 613 describes the analysis of dioxins and furans.

Over the past decade, water pollution control has progressed from an art to a science. Increased emphasis has been placed on the removal of secondary pollutants, such as nutrients and refractory organics, and on water reuse for industrial and agricultural purposes. This in turn has generated both fundamental and appHed research, which has improved both the design and operation of wastewater treatment faciUties. 

Carbon monoxide was discovered in 1776 by heating a mixture of charcoal and 2inc oxide. It provided a source of heat to industry and homes as a component of town gas and was used as a primary raw material in German synthetic fuel manufacture during World War II its compounds with transition metals have been studied extensively (see Carbonyls). Most recently, carbon monoxide emission from vehicle exhausts has been recognized as a primary source of air pollution (qv). 

In addition to using annuahzed cost comparisons in evaluating an air-poUution-control (APC) equipment installation, the impact of the 1990 Clean Air Act Amendments (CAAA) and resulting regulations also must be included in the evaluation. The CAAA prescribes specific pollution-control requirements for particular industries and locations. As an example, the CAAA requires that any major stationary source or... 

As indicated above, industrial wastewater contains avast array of pollutants in soluble, colloidal, and particulate forms, both inorganic and organic. In addition, the required effluent standards are also diverse, varying with the industrial and pohutant class. Consequently, there can be no standard design for industrial water-pohution control. Rather, each site requires a customized design to achieve optimum performance. However, each of the many proven processes for industrial waste treatment is able to remove more than one type of pollutant and is in general applicable to more than one industry. In the sections that follow, waste-treatment processes are discussed more from the... 

Our survey of the activities of the Government, industry and voluntary bodies in the control of pollution discloses several issues which need further enquiry. The first and most difficult of these is how to balance the considerations which determine the levels of public and private expenditure on pollution control. Some forms of pollution bear more heavily on society than others some forms are cheaper than others to control and the public are more willing to pay for some forms of pollution control than for others. There are also short and long-term considerations in the short-term the incidence of pollution control on individual industries or categories of labor may be heavy but. . . what may appear to be the cheapest policy in the short-term may prove in the long-term to have been a false economy. 

Even though society has moved toward centralized industries and utilities, we still have many personal sources of air pollution for which we alone can answer—(1) automobiles, (2) home furnaces, (3) home fireplaces and stoves, (4) backyard barbecue grills, and (5) open burning of refuse and leaves. Figure 6-4 illustrates the personal emissions of a typical U.S. family. 

The energy release and air pollution emissions from personal sources in the United States are greater than those from industry and utilities combined. In any major city in the United States, the mass of pollutants emitted... 

Three factors influence the rate of corrosion of metals—moisture, type of pollutant, and temperature. A study by Hudson (1) confirms these three factors. Steel samples were exposed for 1 year at 20 locations throughout the world. Samples at dry or cold locations had the lowest rate of corrosion, samples in the tropics and marine environments were intermediate, and samples in polluted industrial locations had the highest rate of corrosion. Corrosion values at an industrial site in England were 100 times higher than those found in an arid African location.
