I,  James  K.  McHugh,  certify  that:

1.   I  have  reviewed  this  quarterly  report  on  Form  10-QSB  of  N-Viro
International  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

4.   The  registrant's  other  certifying  officer(s)  and  I am responsible for
establishing  and  maintaining disclosure controls and procedures (as defined in
Exchange  Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial
reporting  (as  defined  in  Exchange Act Rules 13a-15(f) and 15d-15(f)) for the
registrant  and  have:

     (a)  Designed  such  disclosure  controls  and  procedures,  or caused such
disclosure  controls  and  procedures  to  be designed under our supervision, 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  report  is  being  prepared;

     (b)  Designed  such  internal  control  over financial reporting, or caused
such  internal  control  over  financial  reporting  to  be  designed  under our
supervision,  to  provide  reasonable  assurance  regarding  the  reliability of
financial  reporting  and  the  preparation of financial statements for external
purposes  in  accordance  with  generally  accepted  accounting  principles;

(c)  Evaluated  the  effectiveness  of  the registrant's disclosure controls and
procedures  and presented in this report our conclusions about the effectiveness
of  the  disclosure controls and procedures, as of the end of the period covered
by  this  report  based  on  such  evaluation;  and

     (d)  Disclosed  in  this  report  any  change  in the registrant's internal
control  over  financial  reporting  that  occurred during the registrant's most
recent  fiscal quarter (the registrant's fourth fiscal quarter in the case of an
annual  report)  that  has  materially  affected,  or  is  reasonably  likely to
materially  affect,  the registrant's internal control over financial reporting;
and

5.  The  registrant's other certifying officer(s) and I have disclosed, based on
our  most recent evaluation of internal control over financial reporting, to the
registrant's  auditors  and  the  audit  committee  of the registrant's board of
directors  (or  persons  performing  the  equivalent  functions):

(a)  All  significant  deficiencies  and  material  weaknesses  in the design or
operation  of  internal  control  over  financial reporting which are reasonably
likely  to  adversely  affect  the  registrant's  ability  to  record,  process,
summarize  and  report  financial  information;  and

(b)  Any  fraud,  whether  or  not  material,  that involves management or other
employees  who have a significant role in the registrant's internal control over
financial  reporting.
