(a) At closure of a magazine or unit which stored hazardous waste under this subpart, the owner or operator must remove or decontaminate all waste residues, contaminated containment system components, contaminated subsoils, and structures and equipment contaminated with waste, and manage them as hazardous waste unless Sec. 261.3(d) of this chapter applies. The closure plan, closure activities, cost estimates for closure, and financial responsibility for magazines or units must meet all of the requirements specified in subparts G and H of this part, except that the owner or operator may defer closure of the unit as long as it remains in service as a munitions or explosives magazine or storage unit.
(b) If, after removing or decontaminating all residues and making all reasonable efforts to effect removal or decontamination of contaminated components, subsoils, structures, and equipment as required in paragraph (a) of this section, the owner or operator finds that not all contaminated subsoils can be practicably removed or decontaminated, he or she must close the facility and perform post-closure care in accordance with the closure and post-closure requirements that apply to landfills (Sec. 264.310).
Sec. Appendix I to Part 264--Recordkeeping Instructions
The recordkeeping provisions of Sec. 264.73 specify that an owner or operator must keep a written operating record at his facility. This appendix provides additional instructions for keeping portions of the operating record. See Sec. 264.73(b) for additional recordkeeping requirements.
The following information must be recorded, as it becomes available, and maintained in the operating record until closure of the facility in the following manner:
Records of each hazardous waste received, treated, stored, or disposed of at the facility which include the following:
(1) A description by its common name and the EPA Hazardous Waste Number(s) from part 261 of this chapter which apply to the waste. The waste description also must include the waste's physical form, i.e., liquid, sludge, solid, or contained gas. If the waste is not listed in part 261, subpart D, of this chapter, the description also must include the process that produced it (for example, solid filter cake from production of ----, EPA Hazardous Waste Number W051).
Each hazardous waste listed in part 261, subpart D, of this chapter, and each hazardous waste characteristic defined in part 261, subpart C, of this chapter, has a four-digit EPA Hazardous Waste Number assigned to it. This number must be used for recordkeeping and reporting purposes. Where a hazardous waste contains more than one listed hazardous waste, or where more than one hazardous waste characteristic applies to the waste, the waste description must include all applicable EPA Hazardous Waste Numbers.
(2) The estimated or manifest-reported weight, or volume and density, where applicable, in one of the units of measure specified in Table 1;

Sec. Appendixes II-III to Part 264 [Reserved]
Sec. Appendix IV to Part 264--Cochran's Approximation to the Behrens-
Fisher Students' t-test
Using all the available background data (nb readings), calculate the background mean (Xb) and background variance (sb2). For the single monitoring well under investigation (nm reading), calculate the monitoring mean (Xm) and monitoring variance (sm2).
For any set of data (X1, X2, . . ., Xn) the mean is calculated by:[GRAPHIC] [TIFF OMITTED] TC15NO91.174 and the variance is calculated by:[GRAPHIC] [TIFF OMITTED] TC15NO91.175 where ``n'' denotes the number of observations in the set of data.
The t-test uses these data summary measures to calculate a t-statistic (t*) and a comparison t-statistic (tc). The t* value is compared to the tc value and a conclusion reached as to whether there has been a statistically significant change in any indicator parameter.
The t-statistic for all parameters except pH and similar monitoring parameters is:[GRAPHIC] [TIFF OMITTED] TR26OC93.011 If the value of this t-statistic is negative then there is no significant difference between the monitoring data and background data. It should be noted that significantly small negative values may be indicative of a failure of the assumption made for test validity or errors have been made in collecting the background data.
The t-statistic (tc), against which t* will be compared, necessitates finding tb and tm from standard (one-tailed) tables where,tb = t-tables with (nb-1) degrees of freedom, at
the 0.05 level of significance.tm = t-tables with (nm-1) degrees of freedom, at
the 0.05 level of significance.
Finally, the special weightings Wb and Wm are defined as:[GRAPHIC] [TIFF OMITTED] TC15NO91.176 and so the comparison t-statistic is:[GRAPHIC] [TIFF OMITTED] TC15NO91.177
The t-statistic (t*) is now compared with the comparison t-statistic (tc) using the following decision-rule:
If t* is equal to or larger than tc, then conclude that
there most likely has been a significant increase in this
specific parameter.
If t* is less than tc, then conclude that most likely there
has not been a change in this specific parameter.
The t-statistic for testing pH and similar monitoring parameters is constructed in the same manner as previously described except the negative sign (if any) is discarded and the caveat concerning the negative value is ignored. The standard (two-tailed) tables are used in the construction tc for pH and similar monitoring parameters.
If t* is equal to or larger than tc, then conclude that there most likely has been a significant increase (if the initial t* had been negative, this would imply a significant decrease). If t* is less than tc, then conclude that there most likely has been no change.
A further discussion of the test may be found in Statistical Methods (6th Edition, Section 4.14) by G. W. Snedecor and W. G. Cochran, or Principles and Procedures of Statistics (1st Edition, Section 5.8) by R. G. D. Steel and J. H. Torrie.

Sec. Appendix V to Part 264--Examples of Potentially Incompatible Waste
Many hazardous wastes, when mixed with other waste or materials at a hazardous waste facility, can produce effects which are harmful to human health and the environment, such as (1) heat or pressure, (2) fire or explosion, (3) violent reaction, (4) toxic dusts, mists, fumes, or gases, or (5) flammable fumes or gases.
Below are examples of potentially incompatible wastes, waste components, and materials, along with the harmful consequences which result from mixing materials in one group with materials in another group. The list is intended as a guide to owners or operators of treatment, storage, and disposal facilities, and to enforcement and permit granting officials, to indicate the need for special precautions when managing these potentially incompatible waste materials or components.
This list is not intended to be exhaustive. An owner or operator must, as the regulations require, adequately analyze his wastes so that he can avoid creating uncontrolled substances or reactions of the type listed below, whether they are listed below or not.
It is possible for potentially incompatible wastes to be mixed in a way that precludes a reaction (e.g., adding acid to water rather than water to acid) or that neutralizes them (e.g., a strong acid mixed with a strong base), or that controls substances produced (e.g., by generating flammable gases in a closed tank equipped so that ignition can not occur, and burning the gases in an incinerator).
In the lists below, the mixing of a Group A material with a Group B material may have the potential consequence as noted.
Group 1-A Acetylene sludgeAlkaline caustic liquidsAlkaline cleanerAlkaline corrosive liquidsAlkaline corrosive battery fluidCaustic wastewaterLime sludge and other corrosive alkaliesLime wastewaterLime and waterSpent caustic
Group 1-B Acid sludgeAcid and waterBattery acidChemical cleanersElectrolyte, acidEtching acid liquid or solventPickling liquor and other corrosive acidsSpent acidSpent mixed acidSpent sulfuric acid
Potential consequences: Heat generation; violent reaction.
Group 2-A AluminumBerylliumCalciumLithiumMagnesiumPotassiumSodiumZinc powderOther reactive metals and metal hydrides
Group 2-B Any waste in Group 1-A or
1-B
Potential consequences: Fire or explosion; generation of flammable hydrogen gas.
Group 3-A AlcoholsWater
Group 3-B Any concentrated waste in Groups 1-A or 1-BCalciumLithiumMetal hydridesPotassium SO2 Cl2, SOCl2, PCl3, CH3 SiCl3Other water-reactive waste
Potential consequences: Fire, explosion, or heat generation; generation of flammable or toxic gases.
Group 4-A AlcoholsAldehydesHalogenated hydrocarbonsNitrated hydrocarbonsUnsaturated hydrocarbonsOther reactive organic compounds and solvents
Group 4-B Concentrated Group 1-A or 1-B wastesGroup 2-A wastes
Potential consequences: Fire, explosion, or violent reaction.
Group 5-A Spent cyanide and sulfide solutions
Group 5-B Group 1-B wastes
Potential consequences: Generation of toxic hydrogen cyanide or hydrogen sulfide gas.
