Exemption

The following employees are typically exempt from the coverage of 

If an employee is injured during a work assignment outside the state where he is employed, he is still eligible to collect benefits. In some states, benefits are reduced if the employee is not using the safety equipment required by the employer at the time of the injury.

DENDRAL followed a three-stage procedure. In the first phase, the so-called plan, prior knowledge, and heuristics were used to deduce a set of constraints. Constraints could be, for example, the exemption of large sets of candidate solutions or the suggestion for a extensive search over limited classes of solutions. 

Synthetic ethanol is derived from petroleum by hydration of ethylene In the United States some 700 million lb of synthetic ethanol is produced annually It is relatively inexpensive and useful for industrial applications To make it unfit for drinking it is denatured by adding any of a number of noxious materials exempting it from the high taxes most governments impose on ethanol used m beverages... 

Low level blends of ethanol and and gasoline enjoyed some popularity in the United States in the 1970s. The interest persists into the 1990s, encouraged by the exemption of low level ethanol-gasoline blends from the Federal excise tax as well as from state excise taxes in many states. 

In the first years of gasohol use some starting and driveabiUty problems were reported (19). Not all vehicles experienced these problems, however, and better fuel economy was often indicated even though the energy content of the fuel was reduced. Gasohol was exempted from the federal excise tax amounting to a 0.16/L ( 0.60/gal) subsidy. Without this subsidy, ethanol would be too expensive for use even as a fuel additive. 

The toxicological problems associated with asbestos have been widely pubHshed and asbestos has been banned from most uses by the EPA. However, modem diaphragm cell chlorine plants have not had difficulty meeting the required exposure limits for asbestos fibers, and, as of 1990, the chlorine industry had an exemption allowing the continued use of asbestos as a diaphragm material. 

Perfluorinated ethers and perfluorinated tertiary amines do not contribute to the formation of ground level ozone and are exempt from VOC regulations (32). The commercial compounds discussed above have an ozone depletion potential of zero because they do not contain either chlorine or bromine which take part in catalytic cycles that destroy stratospheric ozone (33). 

Colorants. According to U.S. regulations, colorants are divided into two classes certified and exempt (see Colorants for foods, drugs, COSMETICS, AND MEDICAL DEVICES). Batch samples of certified colors must be sent to the FDA for analysis and confirmation that the colorants comply with estabhshed specifications. Color manufacturers pay a small fee for each batch of color that is analy2ed. The number of certified colors available to food technologists has declined. Several of the historical colorants were found to have carcinogenic effects. Table 1 shows the certified colors that are permissible for food use in the United States as of 1993. 

The Energy PoHcy Act of 1992 (H.R. 776) has Hberalized the rules concerning biofuels and provides tax incentives for increased usage. Many states also have gasohol fuel tax exemptions in place, and some have enacted legislation that requites use of oxygenated fuels under certain conditions. Most of these laws impact favorably on biofuels usage. 

The Fair Packaging and Labeling Act, which uses the same definitions for dmgs and cosmetics as the Food, Dmg and Cosmetic Act, only has jurisdiction over retail products sold to the consumer for use at home. This condition exempts free samples and professional use products not sold to a consumer for personal use. 

California and Minnesota have placed restrictions on the disposal of fluorescent light tubes, which contain from 40—50 mg of mercury per tube, depending on size. After batteries, fluorescent lamps are the second largest contributor of mercury in soHd waste streams in the United States (3,14). A California law classifies the disposal of 25 or more fluorescent lamp tubes as hazardous waste. In Minnesota, all waste lamps generated from commercial sources are considered hazardous waste. Private homes are, however, exempt from the law (14). Other states have proposed similar regulations. Several companies have developed technologies for recovering mercury from spent lamps (14). 

The first stage of the Stuart oil shale project near Gladstone, AustraUa, 6000 t/d (6600 short tons /d), is scheduled to be constmcted by Southern Pacific Petroleum. Einancial assistance from the AustraUan government, consisting of special depreciation incentives and exemption of gasoline taxes equivalent to about U.S. 1.91/m of cmde shale oil ( 12.00/bbl) has been assured (68). 

In the words of RSPA, the changes to the regulations will (/) simplify and reduce the volume of the HMR, 2) enhance safety through better classification and packaging, (3) promote flexibiUty and technological innovation in packaging, (4) reduce the need for exemptions from the HMR, and (5) facihtate international commerce (3). 

Subdivision O guidelines for residue chemistry data were originally pubHshed by the EPA in 1982. These have been supplemented to improve the rate of acceptance by EPA reviewers of the many reports submitted by registrants in support of tolerances for pesticides in foods. The residue chemistry studies most frequently rejected include metaboHsm in plants, food processing (qv) studies, and studies on storage stabHity of residues in field samples (57). AH tolerances (maximum residue levels) estabHshed under FIFRA are Hsted in 40 CFR under Sections 180 for individual pesticides in/on raw agricultural commodities, 180 for exemptions from tolerances, 185 for processed foods, and 186 for animal feeds. 

The INDA actually is a request for a Claimed Investigational Exemption to allow the transport of clinical samples of a nonapproved dmg into interstate commerce for the testing in human subjects. 

Several states that have a large number of CPI plants offer various types of tax incentives. Louisiana, for instance, offers a 10-yr tax exemption from property taxes on buildings, equipment, and improvements to land (2). Texas, which has a large petrochemical industry, offers a 7-yr tax abatement program. Neither of these states have a state income tax. Both states offer a tax credit for each job created and provide free worker training. 

Many firms are finding areas such as Ireland, Scotland, Spain, and southern Italy, where unemployment rates are relatively high and governments offer property tax exemptions, grants toward capital investment, low interest loans, and other incentives, attractive from those standpoints. Some of these areas have developed a good infrastmcture based on businesses already attracted to the area. 

Florida, Illinois, Louisiana, Massachusetts, New Jersey, Pennsylvania, and Rhode Island (43). 1-Propanol is allowed as a flavoting substance and adjuvants according to 21 CFR 172.515 (48), and is exempted from the requirement of tolerance when used as a solvent or cosolvent iu pesticide formulations (49) (see Flavors AND spices Pesticides). 

Unless otherwise exempt, a firm must submit a premarket notification, also called a 510(k), to the PDA 90 days before it intends to market a device for the first time (17). The 510(k) submission must contain sufficient information to show that the device in question is substantially equivalent to a legally marketed device for a particular intended use. This notification is also required for a product when there is a change or modification to a product that may significantly affect the safety or effectiveness of the device, or when there is a significant change or modification to the intended use of the device. 

FDA s medical device regulations relating to adulteration and misbranding generally apply to devices intended for use on animals. These devices, however, are exempt from the 510(k) and PMA requirements. FDA has viewed animal grooming products as being outside of its purview. 

Hickman, WiUiams and Company has filed an appHcation for exemption with the U.S. Department of Transportation Administrator for Ha2ardous Materials Safety regarding 50 and 75% ferrosiUcon, and magnesium ferrosiUcon. At this writing (ca 1996), a decision on this appHcation is stiU pending. 

Some limited, volume of tiaffic also may be subject to ceitain rates, terms, and conditions collectively established by a group of carriers pursuant to an agreement between such carriers, if approved and exempted from the antitmst laws by the Surface Transportation Board (STB) (8). Whenever any rate arranged between a shipper and carrier iacorporates provisions of such an agreement, a shipper should request confirmation from the carrier that the carrier is a party to the agreement.
