     The letter addresses several aspects for identifying solvents which are
designated as F-listed wastes.  Currently, The F001-005 listings cover only
solvents used separately.  If individually used solvent waste streams are mixed
after generation, the result is a mixture of F-listed waste streams.  EPA is
developing regulations that will identify spent solvents on the basis of total
solvent contained in the mixture.*
* Refer to Summary/Document //9444.15 for final EPA regulations.

      There are, indeed, several facets to identifying which           CD
 solvents are  P-listed wastes.   I am going to review the               *?
 points we discussed over the phone on March 20th,  in response         *
 to your letter dated March 6,  1985.                                   ^
                                                                       \
      Only those solvents designated in the *P*  series are             **
 listed as "P" solvent wastes.   In the May 19, 1980 Pederal            w
 Register (45  PR 33122), §261.30(5) says that Appendix VII             f
 identifies the constituent which caused SPA to  list the waste in      *
 1261.31 or §261.32 as BP toxic or toxic waste.   In Appendix VII,      v.
 only the listed solvents are specified.  The spent solvent            2-
 listings in f261.31 are worded "The following spent halogenated/      £
 non-halogenated solvents...* which clearly designates only the
 listed solvents.                                                      5
                                                                       y
      Moreover, currently, only solvents used separately are
 covered by the P001-005 listings.  The Agency issued a letter on
 July 21, 1981, to the Safety-Risen Corporation  that stated that
 the $261.31 listings only refer to "...spent solvents identifiable
 as any technical grade of the chemical that is  produced or marketed
.and not to mixtures otherwise containing the chemical.?  (A copy
 of RIL 95 is  enclosed.)  As you observed, this  interpretation
 is consistent with the approach taken in identifying $261.33
 hazardous waste.

      If individually used solvent waste streams are mixed after
 generation, the mixture is a mixture of P-listed waste streams.
 You can see how important it is to be able to identify the
 original source of the wastes in order to classify the mixture.
 Just knowing  the composition of the waste is not enough to
 know what waste code(s)'to apply to the waste.   Regulations
 under development will identify spent solvents  on  the basis of
 total solvent contained in the mixture.

      Pinally, States with authorised programs may  have more
 stringent or  extensive regulations than EPA or  operate a program
 with greater  scope of coverage than EPA according  to S5271.1(1)
 and 271.121(i).  If States designate mixtures of solvents used
