Report of Schneider Downs & Co., Inc.

-------------------------------------------------------

To the Participants and Administrator of the
Ecology and Environment, Inc. 401(k) Plan
Lancaster, New York


We have audited the accompanying statement of net assets available for
benefits of Ecology and Environment, Inc. 401(k) Plan, and the related
statement of changes in net assets available for benefits for the year ended
December 31, 2004 and the supplemental schedule of assets (held at end of
year) as of December 31, 2004.  These financial statements are the
responsibility of the Plan's management.  Our responsibility is to express
an opinion on these financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States).  Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement.  The Plan is not
required to have, nor were we engaged to perform, an audit of its internal
control over financial reporting.  Our audit included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the
purpose of expressing an opinion on the effectiveness of the Plan's internal
control over financial reporting.  Accordingly, we express no such opinion.
An audit includes examining, on a test basis, evidence supporting the
amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement
presentation.  We believe that our audit provides a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan as
of December 31, 2004, and the changes in net assets available for benefits
for the year ended December 31, 2004 in conformity with accounting
principles generally accepted in the United States of America.

Our audit was performed for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The supplemental schedule of assets
(held at end of year) is presented for the purpose of additional analysis
and is not a required part of the basic financial statements, but is
supplementary information required by the Department of Labor's Rules and
Regulations for reporting and disclosure under the Employee Retirement
Income Security Act of 1974.  The supplemental schedule is the
responsibility of the Plan's management.  The supplemental schedule has been
subjected to the auditing procedures applied in the audit of the basic
financial statements and, in our opinion, is fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

at December 31, 2003, and the changes in net assets available for benefits
for the year then ended in conformity with accounting principles generally
accepted in the United States of America.  These financial statements are
the responsibility of the Plan's management.  Our responsibility is to
express an opinion on these financial statements based on our audit.  We
conducted our audit of these statements in accordance with the standards of

standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence

Ecology and Environment, Inc.
401(k) Plan
Notes to Financial Statements
December 31, 2004 and 2003
----------------------------------------------------------------------------

1.   Description of Plan
     -------------------

     The following description of the Ecology and Environment 401(k) Plan
(the Plan) is provided for general information purposes only.  Participants
should refer to the Plan agreement for a more comprehensive description of
the Plan's provisions.  On August 1, 2002, the Plan changed the Recordkeeper
from Dreyfus Retirement Services (Dreyfus) to MFS Retirement Services, Inc.
(MFS) and changed the Trustee from Dreyfus to Reliance Trust Company.  In
connection with these changes, a new plan agreement was adopted on August 1,
2002.

     General
     -------

     The Plan was established January 1, 1994 as a defined-contribution plan
to cover all eligible employees of Ecology and Environment, Inc. (the
Company).  Beginning August 1, 2002 the hours of service requirement was
eliminated and employees age twenty-one or older are immediately eligible to
participate in the plan during the month following their date of hire.
Contributions to the Plan were not permitted prior to July 1, 1994.  The Plan
is subject to the provisions of the Employee Retirement Income Security Act
of 1974.

     Contributions
     -------------

     Participants may elect to make voluntary contributions subject only to
the limitations of the Internal Revenue Code.  The elective deferral
percentage may be modified the first day of any month.  Upon enrollment in
the Plan, a participant may direct their contributions in any combination of
the seventeen investment options in at least 10 percent increments in each
option selected.

     The Company may make contributions in the form of matching contributions
and/or an annual discretionary contribution fixed by appropriate action of
the Company.  There were no Company contributions for the 2004 and 2003 plan
years.

      Participant accounts
     --------------------

     Each participant's account is credited with the participant's
contribution and allocations of the Company's contribution (if any) and
the Plan earnings, and charged with an allocation of administrative expenses.
Allocations are based on participant account balances, as defined in the
Plan documents.  The benefit to which a participant is entitled is the
participant's vested account balance.

     Vesting
     -------

     Participants are immediately vested in their contributions plus actual
earnings thereon.  Vesting in the Company's matching and discretionary
contribution portion of their accounts plus actual earnings thereon is based
on years of continuous service.  A participant is 100% vested in the Company
contributions after five years of credited service.  There is no partial
vesting.

Page 5
------

     Participant loans
     -----------------

     Participants may borrow from their account a minimum of $1,000 with a
maximum equal to the lesser of $50,000 or 50% of their vested account
balance.  Loan transfers are treated as a transfer to (from) the investment
fund from (to) the Loan Fund.  Loan terms range from one to five years or a
reasonable period of time determined when the loan is made for the purchase
of a primary residence.  The loans are collateralized by the balance in the
participant's account and bear interest at a rate commensurate with local
prevailing rates as determined by the Plan Administrator.  Principal and
interest are paid ratably through bi-weekly payroll deductions.

     Payment of benefits
     -------------------

     On termination of service due to death, disability, or retirement, a
participant may elect to receive either a lump-sum amount equal to the value
of the participant's vested interest in his or her account, or monthly,
quarterly, semi-annual or annual installments over a period not to exceed
the life of the participant or the life of a designated beneficiary.

     Administration
     --------------

     The Plan is administered by the Company.  The Company has selected MFS
to be the Recordkeeper of the Plan and Reliance Trust Company as the Trustee.

     Administrative expenses are paid by the participants and the Company.
An asset-based fee is paid by the participants on an annual basis.  This
amount is deducted from participant accounts and placed in a holding
account, which is merged with the MFS Fixed Fund.  Any remaining
administrative expenses in excess of the amounts which are set aside by the
Plan are paid by the Company.

2.   Summary of Accounting Policies
     ------------------------------

     Basis of Accounting:

     The financial statements of the Plan are prepared under the accrual
method of accounting.

     Investments and Related Transactions:

     The Plan's investments are reflected at current market value as measured
by quoted market prices in an active market or as determined in good faith
by the Trustee.  Shares of mutual funds are valued at the net asset value of
shares held by the Plan at year-end.  Net appreciation/(depreciation) in fair
value of investments includes both realized gains and losses and unrealized
appreciation/(depreciation).  Interest and dividend income is recognized as
earned.  Investment transactions are accounting for on the trade date.
Participant loans are valued at cost, which approximates fair value.

Page 6
------

     Payment of Benefits:

     Benefits are recorded when paid.

     Use of Estimates:

     The preparation of the Plan's financial statements in conformity with
generally accepted accounting principles requires the Plan Administrator to
make estimates and assumptions that affect the reported amounts of net
assets and disclosures of contingent net assets at the date of the financial
statements and the reported amounts of changes in net assets during the
reporting period.  Actual results could differ from those estimates.

     Reclassifications:

     Certain 2003 amounts have been reclassified to conform to the 2004
presentation.

3.   Plan Termination
     ----------------

     Although it has not expressed any intent to do so, the Company has the
right under the Plan to discontinue at any time and to terminate the Plan
subject to the provisions of ERISA.  In the event of Plan termination,
participants will become 100 percent vested in their accounts.

4.   Tax Status
     ----------

     The Plan Administrator has not applied to the Internal Revenue Service
for a determination letter for the Plan.  The Plan was based upon a prototype
plan designed by MFS Retirement Services, Inc. and received a favorable
determination letter dated April 23, 2002.  The Plan has been amended since
receiving the determination letter.  However, the Plan Administrator and the
Plan's legal counsel believe that the Plan is currently designed and being
operated in compliance with the applicable requirements of the Internal
Revenue Code.  Therefore, no provision for income taxes has been included in
the Plan's financial statements.
