EXHIBIT 99.4

I,  James  R.  Baumgardner,  certify  that:

1.   I  have  reviewed  this  quarterly  report on Form 10-Q of American Ecology
     Corporation;

2.   Based  on  my  knowledge, this quarterly report does not contain any untrue
     statement  of a material fact or omit to state a material fact necessary to
     make  the  statements  made, in light of the circumstances under which such
     statements  were made, not misleading with respect to the period covered by
     this  quarterly  report;

3.   Based  on  my  knowledge,  the  financial  statements,  and other financial
     information  included  in  this  quarterly  report,  fairly  present in all
     material  respects  the financial condition, results of operations and cash
     flows  of  the  registrant  as  of,  and for, the periods presented in this
     quarterly  report;

4.   The  registrant's  other  certifying  officers  and  I  are responsible for
     establishing and maintaining disclosure controls and procedures (as defined
     in  Exchange  Act  Rules 13a-14 and 15d-14) for the registrant and we have:

     a)   designed  such  disclosure  controls  and  procedures  to  ensure that
          material  information  relating  to  the  registrant,  including  its
          consolidated  subsidiaries, is made known to us by others within those
          entities,  particularly  during  the  period  in  which this quarterly
          report  is  being  prepared;

     b)   evaluated  the  effectiveness  of the registrant's disclosure controls
          and procedures as of a date within 90 days prior to the filing date of
          this  quarterly  report  (the  "Evaluation  Date");  and

     c)   presented  in  this  quarterly  report  our  conclusions  about  the
          effectiveness  of  the disclosure controls and procedures based on our
          evaluation  as  of  the  Evaluation  Date;

5.   The  registrant's  other certifying officers and I have disclosed, based on
     our  most  recent  evaluation,  to  the registrant's auditors and the audit
     committee  of  registrant's  board  of directors (or persons performing the
     equivalent  function):

     a)   all  significant  deficiencies  in the design or operation of internal
          controls  which  could  adversely  affect  the registrant's ability to
          record,  process,  summarize  and  report  financial  data  and  have
          identified  for  the  registrant's auditors any material weaknesses in
          internal  controls;  and

     b)   any  fraud, whether or not material, that involves management or other
          employees  who  have  a  significant role in the registrant's internal
          controls;  and

6.   The  registrant's  other  certifying  officers and I have indicated in this
     quarterly  report whether or not there were significant changes in internal
     controls  or  in  other  factors  that  could significantly affect internal
     controls  subsequent  to  the date of our most recent evaluation, including
     any corrective actions with regard to significant deficiencies and material
     weaknesses.
