Regulatory lists

Some sites are easy to elassify due to their inehision on the National Priorities List (NPL), state superfund, or other regulatory list. In other eases, debate ean and does arise to determine if a site should be treated as hazardous. Eor example, some sites eommonly referred to as brown fields have eontamination levels that are eonsidered low. Sometimes levels of eontamination are so low that exposure levels to workers do not reaeh aetion levels or permissible exposure levels (PEL). Some firms have ehosen to treat low-level eontaminated sites as if they fell under HAZWOPER requirements. This is a somewhat eonservative approaeh whieh provides a eomfort faetor for management and potentially responsible parties (PRP) or other entities. 

ChemAdvisor and the List Of Lists. ChemAdvisor and the LOLI (List Of Lists) Database contains over 2700 regulatory lists from around the world, including environmental, health and safety, international, inventories, and reference material necessary for Material Safety Data Sheet preparation. ... 

The GreenList system also includes a kind of wild card . When a chemical is found on a regulatory list or banned in a country, it is considered to have Other Significant Concerns (OSCs). OSCs are applied to the overall rating of a chemical - not its individual attributes -to reduce the overall score by one point. For example chemicals have OSCs if they are ... 

NFPA confirmed the intent of NFPA 704 and the instability rating system through correspondence with CSB staff. The committee clarified that the rating system is insufficient for use as the sole basis of determining reactivity for regulatory lists because it considers only one facet of chemical reactivity. NFPA staff reiterated this position in testimony given at the CSB public hearing on reactive chemical safety on May 30, 2002. 

Regulatory Constraints The presence or absence of a solvent on various regulatory lists, for example, SARA 313, can either restrict or increase the cost of its use. 

This approach enables the early identification of materials that appear on regulatory lists and/or whose use on a larger scale will be accompanied by the need for significant engineering or abatement controls to protect staff, property, and the environment, or in some cases may even be prohibited, all of which adds cost to a development program in terms of both time and money. 

Toluene, or methylbenzene, is the second most water-soluble hydrocarbon found in refined gasoline and is on the EPA s regulatory list of pollutant chemicals. Contrary to belief of only a very few years ago, toluene is now known to be biodegradable under a wide variety of anaerobic conditions (Table 3.2). Research on this topic has progressed rapidly and reached the point where several isolates have been obtained and different metabolic pathways have been proposed.

Under RCRA, waste producers are required to take a cradle to grave approach to waste management. The producer of the waste is legally liable from the moment that waste is produced until its final disposal. A waste generator must identify waste material as hazardous waste if it is on a regulatory list or has a characteristic of flammability, toxicity, corrosivity, or reactivity. Once a material has been identified as hazardous waste, it must be clearly labeled and tracked when in transport. The waste must be treated in special facilities to low levels of contaminants. The final residual solid material, for example, incinerator ash, must be disposed into a registered hazardous waste landfill. 

This collection contains full text Material Safety Data Sheets, Summary Sheets, and Label Data for more than 59000 substances, including pure substances and mixtures, 92-96% of which are the most heavily used chemicals in industry. The database originated with Occupational Health Services, Inc. (OHS). The records include occupational, environmental, and regulatory data, as well as names, CAS Registry Numbers, and regulatory list numbers. The OHS online system provides a full file, a summary information file, and a file composed of records to chemicals used in the manufacture of pesticide and other agricultural chemical products (OHS, STN available on CD from OHS). 

In terms of the chemicals, we the editors of this book made a personal selection based on our own knowledge of those with relatively high toxicity, exposure, production, controversy, newsworthiness, or other interest. The chemicals do not represent a merger of regulatory lists or databases of chemicals they are what we consider to be, for one reason or another, chemicals of concern to toxicology. The book was not intended as a large-scale compendium of toxic chemicals, several of which already exist. 

Chlorinated methanes are on the regulatory list by Occupational Safety and Health Administration (OSHA) as a suspected carcinogen. They are also considered to take part in the destruction of the earth s ozone layer [159],... 

Listed HAP materials may appear as pure compounds, as components of a chemical mixture, or as a by-product of a chemical reaction. Regardless of a facility s pollutant type, the pollutant must be categorized, its levels quantified and then compared to regulatory listings and de minimis reporting levels. If a facility emits criteria or other regulated pollutants in excess of specified levels, it is classified as a major source (see description below). The major source threshold varies by location and pollutant. 

Government Institutes, Inc., 1993, ISBN 0-86587-337-2,345pages. 67. This book Includes 72 regulatory lists from the Air Pollutants Ust. Land Ban Lists. National Priorities List, Toxicity Characteristic List. OSHA Z Tables, and more. 

Chemical any element, eompound or mixture of elements and/or compounds. A substance that a) possesses potentially hazardous properties (including, but not limited to flammability, toxicity, corrosivity, reactivity) or b) is included on any federal, state, or local agency regulatory list or c) is assoeiated with an MSDS and is not an Article as defined in 29CFR1910.1200. For the purposes of this document this definition also applies to chemical product (see definition).

Entries appear regardless of whether they are legal shipping names e.g., Activated carbon appears in many regulatory lists and references Carbon, activated, the proper shipping description. Both are included in the Glossary.
