                                                                     -----------

                                 CERTIFICATION

I, James K. McHugh, certify that:

1.     I  have  reviewed  this  annual  report  on Form 10-K, as amended by Form
10-K/A  (Amendment  No.  2),  of  N-Viro  International  Corporation;

2.     Based  on  my  knowledge,  this annual 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 report;

3.     Based  on  my  knowledge,  the  financial statements, and other financial
information  included  in  this  annual  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  report;

4.     The  registrant's  other  certifying officer(s) and I are 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.
