WHO MUST COMPLETE THIS FORM?
                    INSTRUCTIONS:
Form WM Part I, describing efforts undertaken to implement waste minimization programs, must
be completed by all generators required to file an Annual/Biennial Report. This requirement was
established  in response to  statutory  provisions  included in  the Hazardous  and  Solid  Waste
Amendments of 1984 (HSWA).

NOTE:  Generators shipping hazardous waste off site are required to certify, on Item 16 of the
Uniform Hazardous Waste Manifest, that they have a program in place to reduce, to the degree
determined  economically practicable, the volume and toxicity  of hazardous waste generated. A
similar certification must also  be  made by  generators who have obtained a RCRA treatment,
storage, or  disposal  permit.  Consistent with these certification requirements, generators must
report, on Form WM Part I, the efforts undertaken to implement waste minimization programs.

Please read the detailed instructions on page 25 of the 1987  Hazardous Waste Generation and
Shipment Report Instructions booklet before completing this form.

Answer questions 1 through 10. Throughout this form enter "DK" if the information requested is not
known or is not available; enter "MA" if the information requested is not applicable.

       assessment or audit is a procedure that identifies practices that can be implemented to reduce the generation of
       hazardous waste or the quantity which must subsequently be treated, stored or disposed.

                                                    PART II
  WHO MUST COMPLETE THIS FORM?   Form WM Part II must be completed only by generators that engaged in an activity during 1987 that
                                               resulted in waste minimization.


                                               Waste minimization means:
                                               (1) reduction in the volume and/or toxicity of hazardous waste generated as a result of source

                                               (2) reduction in the volume and/or toxicity of hazardous waste subsequently treated, stored, or
                                               disposed as a result of on-site or off-site recycling.

                                               Mark E| and do not complete this form if no waste minimization results were achieved during 1987.

                         INSTRUCTIONS:   Please read the  detailed instructions beginning on page  26 of the 1987 Hazardous Waste

                                               Make and complete a photocopy of this form for each hazardous waste minimized in 1987.
