Alternative treatment standards

This series of prohibitions restricts how wastes subject to LDR requirements are handled. The most visible aspect of the LDR program is the disposal prohibition, which includes treatment standards, variances, alternative treatment standards (ATSs), and notification requirements. Land disposal means placement in or on the land, except in a corrective action unit, and includes, but is not limited to, placement in a landfill, surface impoundment, waste pile, injection well, land treatment facility, salt dome formation, salt bed formation, underground mine or cave, or placement in a concrete vault, or bunker intended for disposal purposes. The other two components work in tandem with the disposal prohibition to guide the regulated community in proper hazardous waste management. The dilution prohibition ensures that wastes are properly treated, and the storage prohibition ensures that waste will not be stored indefinitely to avoid treatment.

Lab packs Laboratories commonly generate small volumes of many different listed hazardous wastes. Rather than manage all these wastes separately, labs often consolidate these small containers into lab packs. Trying to meet the individual treatment standards for every waste contained in a lab pack would be impractical. To ease the compliance burden, U.S. EPA established an ATS for lab packs that allows the whole lab pack to be incinerated, followed by treatment for any metal in the residues. Treatment using this alternative standard satisfies the LDR requirements for all individual wastes in the lab pack. 

Soil Cleanup, or remediation, of hazardous waste sites will often produce contaminated soil. Contaminated soil must be handled as hazardous waste if it contains a listed hazardous waste or if it exhibits a characteristic of hazardous waste. As with hazardous waste, land disposal of hazardous soil is prohibited until the soil has been treated to meet LDR standards. These contaminated soils, due to either their large volume or unique properties, are not always amenable to the waste codespecific treatment standards. Because of this, U.S. EPA promulgated alternative soil treatment standards in 268.49 in May 1998. The alternative soil treatment standards mandate reduction of hazardous constituents in the soil by 90% or 10 times UTS, whichever is higher. Removal of the characteristic is also required if the soil is ignitable, corrosive, or reactive. 

Clinicians should be aware that many of their patients may be taking alternative treatments either via self-care or prescribed by CAM practitioners. Inquiring about this should be routine because of potential side effects and drug interactions. A working knowledge of CAM treatments will allow child psychiatrists to give parents and patients advice about safety and effectiveness. Use of St. John s wort in children with unipolar depression may at times be appropriate, particularly in cases where more standard treatments are contraindicated or have failed. However, it should be used cautiously and with an appropriate explanation of its risks and benefits, as a competent clinician would do for any treatment. Use of St. John s wort for other conditions is not currently recommended given the lack of evidence for efficacy. Kava extracts may be used for anxiety, with similar provisos. There are much fewer data about the efficacy and safety of other dietary supplements and their use cannot be supported at this point. 

In addition, the use of lithium as an augmentation to standard antidepressants has been the most effective strategy in partially responsive depressive episodes (see Alternative Treatment Strategies later in this chapter). 

An alternative treatment of the correction of order Z a) Za) m/M)m was given in [4]. The idea of this work was to modify the standard definition of the proton charge radius, and include the first order quantum electrodynamic radiative correction into the proton radius determined by the strong interactions. Prom the practical point of view for the nS levels in hydrogen the recipe of [4] reduces to elimination of the constant 11/72 in (5.6) and omission of the Pauli correction in (5.7). Numerically such a modification reduces the contribution to the lA energy level in hydrogen by 0.14 kHz in comparison with the naive result in (5.6), and increases it by 0.03 kHz in comparison with the result in (5.8). Hence, for all practical needs at the current level of experimental precision there are no contradictions between our result above in (5.8), and the result in [4]. 

Technical requirements on treatment and disposal of spent fuel, high-level waste, and transuranic waste established under AEA should be largely unaffected by the presence of waste classified as hazardous under RCRA Some of these wastes meet technology-based treatment standards for hazardous chemical waste established by EPA (e.gvitrified high-level waste is an acceptable waste form under RCRA). Alternatively, a finding that disposal of the radioactive component of the waste complies with applicable environmental standards established by EPA under AEA can serve to exempt the disposal facility from prohibitions on disposal of restricted hazardous chemical wastes under RCRA [e.g., disposal of mixed transuranic waste at the Waste Isolation Pilot Plant (WIPP)]. 

Randomized trial data suggest that unprotected carotid angioplasty can be performed with results comparable to those of CEA (5,6), and some authors have suggested that filter-type EPDs use might be associated with an increased propensity to embolism (38), Nevertheless, we believe that utilization of embolic protection should be considered the standard of care in carotid stenting. When use of an EPD is precluded by anatomical factors, alternative treatment strategies (CEA, medical therapy) must be strongly considered. 

The synthetic utility of the Wolff-Kishner reduction has been the subject of several reviews. However, the latest of these is over 20 years old and fails to incorporate adequately many of the important advancements which have occurred in the past 25 years. This is particularly evident regarding the emergence over the past two decades of the above-mentioned reductions of sulfonylhydrazones with hydride donors as alternatives to standard Wolff-Kishner conditions. Consequently, this discussion will focus primarily on the period since the last major review (1968), although some overlap with earlier work is essential for continuity and completeness. For further information and references to the older literature, the excellent aforementioned treatments should be consulted. Reference 3 contains extensive tables of Wolff-Kishner reductions up to about 1947. 

We should note the absence of dose standardization and probably of randomization because Lind s two seawater patients were noted to have tendons in the ham rigid , unlike the others. However, the result had been crudely replicated by using n = 2 in each group. If we accept that the hypothesis was that the citrus-treated patients alone would improve (Lind was certainly skeptical of the anecdotal support for the other five alternative treatments), then, using a binomial probability distribution, the result has p = 0.0075. But statistics had hardly been invented, and Lind had no need of them to interpret the clinical significance of this brilliant clinical trial.
