Waste Control Regulations

Pollution control and waste disposal are now under strict regulation at federal, state, and local levels. Enforcement of these regulations has also become more effective. Increased public awareness and media coverage make it difficult for today s polluter to hide behind a screen of ignorance. 

Local regulations are sometimes more restrictive than federal or state laws and should be carefully studied by a laboratory

SPECIAL WASTE Controlled waste which is subject to special regulations regarding its control and disposal because of its difficult or dangerous characteristics. The UK definition of special waste is similar, but not identical, to the EC s hazardous waste. 

While a number of wastes produced at the wellsite are considered characteristic hazardous waste, some wastes fall under the nonhazardous description. The regulation of these fall under RCRA Subtitle D. Initially Subtitle D wastes were regulated to control dumping of domestic trash and city runoff. The EPA is considering promulgating regulation of certain oil and gas wastes under Subtitle D [231]. 

The use of wells for disposal of industrial wastes dates back to the 1930s, but this method was not used extensively until the 1960s, when it was implemented primarily in response to more stringent water pollution control regulations. 

Chemical analyses are mainly used for detecting hazard of liquid and solid wastes [175]. Governmental orders and laws regulate the evaluation of hazard of effluent by toxicological tests. Waste control includes the determination of 30 chemical parameters, coliform count, and the result of ecotoxicological test (D. magna test). Category of toxicity ... 

The hazardous waste identification regulations that define the characteristics of toxicity, ignitability, corrosivity, reactivity, and the tests for these characteristics, differ from state to state. In addition, concentration limits may be set out by a state for selected persistent and bioaccumulative toxic substances that commonly occur in hazardous substances. For example, the California Hazardous Waste Control Act requires the California State Department of Health Services (CDHS) to develop and adopt by regulation criteria and guidelines for the identification of hazardous wastes and extremely hazardous wastes.

Appendices G through J identify the regulatory agencies that may be contacted with questions on the management of hazardous wastes. Appendix F has Form DHS 8400 (6/87). This form can be used to obtain copies of California hazardous waste control laws and regulations. 

Identify penalties for non-compliance with hazardous waste control laws and regulations. 

However, emission control dust or sludge from ferrochromium and ferrochromium-silicon production is listed as hazardous waste by EPA (1988b). The processed wastes from several chromium chemical industries are designated as hazardous wastes as well (EPA 1981), and disposal of process wastes is regulated by the EPA. Land filling appears to be the most important method for the disposal of chromium wastes generated by chemical industries. Of the total chromium released in the environment by chemical industries, 82.3% is released on land. An equally large amount of chromium waste is transferred off-site (see Section 5.2). It is anticipated that most of this off-site waste will be disposed of in landfills after proper treatment. It is important to convert chromium wastes into forms of chromium... 

The SO2 scrubbing tower described in Problem 4.26 is to be used to reduce the SO2 mole fraction in the waste gas to a level that meets air quality control regulations. The solvent feed rate must be large enough to keep the SO2 mass fraction in the exit liquid below a specified maximum value. 

Under Subtitle C of the Resource Conservation and Recovery Act (RCRA), certain wastes containing designated TPH compounds and petroleum-related industrial wastes are listed as hazardous. However, RCRA excludes some TPH-related wastes from regulations (e.g., certain exploration, well development, and productions wastes). The RCRA-listed wastes are also controlled under the Comprehensive Environmental, Response, Compensation, and Liability Act (CERCLA) for accidental releases to the environment. 

Chemical control in the Philippines is covered by the 1990 Toxic Substances and Hazardous Wastes Control Act (TSHWCA). The rules and regulations of this Act cover import, manufacture, processing, handling, storage, transport, sale, distribution, use and disposal of chemical substances and mixtures that present an unreasonable risk to human health or the environment. However, chemicals controlled by other Philippine legislation are not covered by TSHWCA. The Act is administered by the Department of Environment and Natural Resources (DENR). 

A) any substance designated pursuant to Section 311(b)(2)(A) of the Federal Water Pollution Control Act, (B) any element, compound, mixture, solution, or substance designated pursuant to section 102 of this Act, (C) any hazardous waste having the characteristics identified under or listed pursuant to section 3001 of the Solid Waste Disposal Act (but not including any waste the regulation of which under the Solid Waste Disposal Act has been suspended by Act of Congress), (D) any toxic pollutant listed under section 307(a) of the Federal Water Pollution Control Act, (E) any hazardous air pollutant listed under section 112 of the Clean Air Act, and (F) any imminently hazardous chemical substance or mixture with respect to which the Administrator has taken action pursuant to section 7 of the Toxic Substances Control Act. 

Reboiler and condenser controls regulate the energy inflow and outflow in a distillation column. These controls must adequately respond to column changes, minimize transmission of distimhances into the column, and be energy efficient. Failure to achieve the first two functions will lead to column instabilities failme to achieve the third wastes energy.
