Reduction of Process Complexity for Distributed Chemical Manufacture... 

A listed toxic chemical manufactured during a process where the chemical remains in a mixture or trade name product distributed by the facility. 

A chemical manufactured at the facility that does not remain in a product distributed by the facility. A threshold determination must be made on the annual quantity of the chemical manufactured regardless of the concentration. For example, quantities of formaldehyde created as a result of waste treatment must be applied toward the threshold for manufacture of this chemical, regardless of the concentration of this chemical in the wastestream. 

On January 1, 1977, the chemical industry truly became a regulated industry. The environmental laws up until that time had covered some chemicals, but had been media oriented. That is — they were concerned about certain chemicals that escaped as emissions or pollutants to various media - the air, our water, contaminated our food or entered the workplace. TSCA changed that direction. It was designed to regulate commerce on chemical substances. TSCA potentially applies to all chemicals manufactured, processed, distributed or used in the U.S. except those chemicals already regulated under certain other federal laws. TSCA affects not only the chemical industry itself, but the many other industries whose products are chemical in nature. This includes most all industrial products. 

Several voluntary industry initiatives, such as ACC s Responsible Care and NACD s Responsible Distribution Process (RDP), provide guidance on process safety management for chemical manufacturers and distributors. However, no voluntary industry initiatives list specific codes or requirements for reactive hazard management. 

Fortunately, however, many small water treatment service companies with limited in-house chemical manufacturing technology will implement strategies designed to overcome their inherent competitive weaknesses. They will, for example, seek larger and often foreign water treatment businesses (perhaps in the United States or Europe) and obtain local distribution rights for importation of quality chemical products. 

Toxic Substances Control Act (TSCA) Enacted in 1976, the TSCA provides the EPA with the authority to require testing and to regulate chemicals, both old and new, entering the environment. It was intended to supplement sections of the Clean Air Act, the Clean Water Act, and the Occupational Safety and Health Act that already provide for regulation of chemicals. Manufacturers are required to submit information to allow the EPA to identify and evaluate the potential hazards of a chemical prior to its introduction into commerce. The act also provides for the regulation of production, use, distribution and disposal of chemicals, toxicant See poison, toxicokinetics See pharmacokinetics. 

During preclinical development, the structure, physical and chemical characteristics, and stereochemical identity of the IND/CTA candidate are fully characterized. This information, for example, is required for the chemical manufacture and control (CMC) section of the IND. Appropriate bioanalytical methods are developed for the evaluation of pharmacokinetics, typically a series of studies focusing on absorption, distribution, metabolism, and excretion (ADME) in toxicology species, as well as systemic exposure and metabolism in toxicological and clinical studies. 

Safety information supplied by the manufacturer on a chemical container should be seen by students who actually use the chemical. If you distribute chemicals into smaller containers to be used by students, copy the hazard and precautionary information from the original label onto the labels for the students containers. Students interested in graphic design may be able to help you perform this task. Labels for many common chemicals may be found here http //beta.ehs.cornell.edu/labels/cgi-bin/label selection.pl... 

The Philippines Inventory of Chemicals and Chemical Substances (PICCS) was published in April 1996. It contains approximately 24,000 chemicals and chemical substances. Chemicals manufactured, imported, distributed, or used in the Philippines in the 5 years prior to December 31, 1993 were nominated for inclusion in the Inventory.24-25...
