                      PART I - FINANCIAL INFORMATION

              SPECIAL NOTICE REGARDING FORWARD-LOOKING STATEMENTS

The Company is including the following cautionary statement in this Form 10-Q
to make applicable and take advantage of the 'safe harbor' provisions of the
Private Securities Litigation Reform Act of 1995 for any forward-looking
statement made by, or on behalf of, the Company.  This 10-Q, press releases
issued by the Company, and certain information provided periodically in
writing and orally by the Company's designated officers and agents contain
statements which constitute forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934.  The words expect, believe, goal, plan, intend,
estimate, and similar expressions and variations thereof used are intended to
specifically identify forward-looking statements. Where any such forward-
looking statement includes a statement of the assumptions or basis underlying
such forward-looking statement, the Company cautions that, while it believes
such assumptions or basis to be reasonable and makes them in good faith,
assumed facts or basis almost always vary from actual results, and the
differences between assumed facts or basis and actual results can be material,
depending on the circumstances.  Where, in any forward-looking statement, the
Company, or its management, expresses an expectation or belief as to future
results, such expectation or belief is expressed in good faith and believed to
have a reasonable basis, but there can be no assurance that the statement of
expectation or belief will result or be achieved or accomplished.

                       OP-TECH ENVIRONMENTAL SERVICES, INC.
                           AND WHOLLY-OWNED SUBSIDIARIES

                NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1. Basis of Presentation

The accompanying unaudited consolidated financial statements have been
prepared in accordance with accounting principles generally accepted in the
United States of America for interim financial information and with the
instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they
do not include all of the information and footnotes required by accounting
principles generally accepted in the United States of America for complete
financial statements.  In the opinion of management, quarterly results include
all adjustments (consisting of only normal recurring adjustments) that the
Company considers necessary for a fair presentation of such information for
interim periods.

The unaudited financial statements include the accounts of the Company and its
two wholly-owned subsidiaries; OP-TECH Environmental Services, Ltd, an
inactive Canadian  company, and OP-TECH AVIX, Inc., a company formed in
January 2002 for purposes of pursuing and engaging in diversified lines of
business including asset management services. All material intercompany
transactions and balances have been eliminated in consolidation.

The balance sheet at December 31, 2003 has been derived from the audited
balance sheet included in the Company's annual report on Form 10-K for the
year ended December 31, 2003.


2. Revenue Recognition

The timing of revenues is dependent on the Company's backlog, contract awards,
and the performance requirements of each contract.  The Company's revenues are
also affected by the timing of its clients planned remediation work as well as
the timing of unplanned emergency spills.  Historically, planned remediation
work generally increases during the third and fourth quarters.  Although the
Company believes that the historical trend in quarterly revenues for the third
and fourth quarters of each year are generally higher than the first and
second quarters, there can be no assurance that this will occur in future
periods.  Accordingly, quarterly or other interim results should not be
considered indicative of results to be expected for any quarter or for the
full year.


3. Related Party Transactions

The Company utilizes subcontract labor purchased from St. Lawrence Industrial
Services, Inc., which is owned by a director of the Company.  The costs for
these services amounted to approximately $300,000 and $798,000 for the six
months ended June 30, 2004 and 2003, respectively, and $179,000 and $426,000
for the three months ended June 30, 2004 and 2003 respectively.


4. Earnings per Share

Basic earnings per share is computed by dividing net income by the weighted
average shares outstanding.  Diluted earnings per share includes the
potentially dilutive effect of common stock equivalents, which include
outstanding options under the Company's Stock Option Plan and warrants that
were issued to a financial advisor in May 2002 to purchase 480,000 shares of
common stock at $0.066 per share, expiring in May 2007.


                                      7.
<PAGE>



5.  Stock Based Compensation

The Company applies APB Opinion 25 and related interpretations in accounting
for its stock option plan.  Accordingly no compensation cost has been
recognized for non-qualified stock options issued.  Had compensation cost for
these options been determined based on their fair value at the grant date
consistent with the method proscribed under Financial Accounting Standards
Board ("FASB") Statement No. 123 "Accounting For Stock-Based Compensation",
the Company's net income (loss) and per share amounts reported for the periods
ended June 30, 2004 and 2003 would not be materially different.  The Company
does not intend to adopt the fair value accounting for stock based
compensation in accordance with FASB Statement No. 148 "Accounting for Stock-
Based Compensation - Transition and Disclosure, an Amendment of FASB Statement
No. 123".

In March 2004 a holder of options to purchase common stock at $.10 per share
exercised those options resulting in the issuance of 3,333 shares of common
stock.


6.  Income Taxes

The Company has recognized a tax benefit of $36,000 in the six months ended
June 30, 2004 as the benefit is expected to be realized during the current
year.


7.  Subsequent Events

On July 13, 2004 options to purchase 88,329 shares of common stock were
exercised.  The total proceeds received from the exercise of the options was
$5,300.

On August 9, 2004 certain officers and directors of the Company provided a
total of $295,000 to the Company to help fund short-term operating cash
requirements.  The loans to the Company are evidenced by promissory notes,
are uncollateralized, bear interest at 8%, and are payable on March 31, 2005.
Following are the officers and directors who provided funds to the Company
under these loans:


            Robert J. Berger         Chairman of Board          $200,000
            George W. Lee            Director                     50,000

                                                                $295,000
                                                                ========

                       PART I  FINANCIAL INFORMATION

Item 2. Management's Discussion and Analysis of Financial Condition and
        Results of Operations.


                       LIQUIDITY AND CAPITAL RESOURCES

At June 30, 2004, the Company had cash of $0 as compared to $58,073 at
December 31, 2003.  The Company voluntarily applies all available cash in the
Company's operating account to pay down the Company's note payable to bank
under its line of credit.

At June 30, 2004, the Company had working capital of $1,746,956 compared to
$1,779,382 at December 31, 2003, with a current ratio of 1.45 to 1 at June
30, 2004 and 1.62 to 1 at December 31, 2003.

For the six months ended June 30, 2004, the Company's net cash used in
operations was $203,440 compared to net cash provided by operations of
$179,114 during the six months ended June 30, 2003.  The cash used in
operations for the six months ended June 30, 2004 was primarily a result of a
net increase in accounts receivable and decrease in net income.

The Company's net cash used in investing activities of $473,067 during the
first six months of 2004 was attributable to the purchase of various field
equipment.

Cash provided by financing activities for the six months ended June 30, 2004
was $618,434, which was primarily due to the net proceeds from the Company's
long-term debt used to finance the Company's investing activities and
operating activities.

As of June 30, 2004, the Company had a loan agreement that provided for
borrowings up to $2,600,000 on a revolving basis, collateralized by all
accounts receivable, inventory and equipment now owned or acquired later.  The
loan has a "step down" provision to $2,000,000 on October 1, 2004.  Amounts in
excess of $2,000,000 have been included in the current portion of long-term
debt at June 30, 2004    The loan is payable on May 31, 2006, bears interest
at a rate of prime plus 1.25 percent, is subject to certain restrictive
financial covenants, and is subject to default if there is a material adverse
change in the financial or economic condition of the Company.  As of June 30,
2004, borrowing against the revolving loan aggregated $2,432,803.  At June 30,
2004 the Company was not in compliance with certain restrictive covenants.
The bank has waived the compliance with the covenants for the quarters ended
June 30, 2004 and September 30, 2004.

In addition, officers and directors of the Company have committed to provide
subordinated debt to the Company in the amount of $545,000.  $295,000 of this
amount was provided on August 9, 2004.

During the first six months of 2004, all principal payments on the Company's
debt were made within payment terms.

The Company expects, based on its operating results and the continued
availability of its line of credit and additional debt provided from certain
directors and officers, that it will be able to meet obligations as they come
due.

On July 13, 2004 options to purchase 88,329 shares of common stock were
exercised.  The total proceeds received from the exercise of the options was
$5,300.

                          RESULTS OF OPERATIONS

                                BILLINGS

The Company's project billings for the second quarter of 2004 decreased 3% to
$4,027,929 from $4,170,620 for the second quarter of 2003.  For the six-month
period ended June 30, 2004 the Company's billings have decreased 3% to
$7,289,991 from $7,486,838 for the same period in 2003.

When comparing the first six months of 2004 to the same period in 2003, the
overall decrease in billings is due primarily to one large remediation project
in 2003 in the Buffalo, NY area that has been offset by several medium sized
emergency projects in the Rochester and Plattsburgh areas.  Overall, the
Company's large emergency projects are down 6% in the first six months of 2004.


                      PROJECT COSTS AND GROSS MARGIN

Project costs for the second quarter of 2004 decreased 5% to $2,824,446 from
$2,968,386 for the same period in 2003.  Project costs as a percentage of
revenues were 70% and 71% for the three months ended June 30, 2004 and 2003,
respectively.  Gross margin for the second quarter of 2004 increased to 30%
from 29% for the same period in 2003.

For the six-month period ended June 30, 2004, project costs decreased 5% to
$4,992,222 from $5,240,065 for the six months ended June 30, 2003. Project
costs as a percentage of revenues were 69% and 70% for the six months ended
June 30, 2004 and 2003, respectively. Gross margin for the six months ended
June 30, 2004 increased to 31% from 30% for the same period in 2003.

As a result of decreased billings, project costs also decreased.  The increase
in the gross margin is due to improved project management as well as a vendor
consolidation program that has resulted in volume discounts on project
material purchases.



                              OPERATING EXPENSES

Operating expenses for the quarter ended June 30, 2004 increased 22% to
$1,130,005 from $923,453 for the same period in 2003. For the six-month period
ended June 30, 2004, operating expenses increased 16% to $2,329,078 from
$2,004,497 for the same period in 2003.  Operating expenses as a percentage of
revenues was 32% and 27% for the six months ended June 30, 2004 and 2003,
respectively.

When comparing the first six months of 2004 to 2003, the overall increase in
operating expenses is due to several factors:

-Payroll expense and related payroll taxes and benefits increased 15% to
$1,224,070 in the first six months of 2004 from $1,066,554 in the same period
in 2003. During the fourth quarter of 2003 and the first two quarters of 2004,
new employees were added in the Cleveland, Edison, Albany, Syracuse and
Massena branch offices.  Each of these offices added new employees as a result
of anticipation of increased sales volume and long-term growth plans.

-Business insurance increased 28% to $142,183 when comparing the first six
months of 2004 to the same period in 2003.  This increase in insurance expense
is due to a single one-time loss resulting in a significant claim being paid
out of the Company's general liability insurance policy.

                                        11.
<PAGE>



-Equipment expense net of usage credit has increased to $89,569 in the first
six months of 2004 from $46,945 in the same period in 2003.  The increase in
net equipment expense is primarily attributed to the higher than anticipated
fuel prices.

-Occupancy expense increased 7% to $191,472 when comparing the first six
months of 2004 to the same period in 2003.  This increase in occupancy expense
is attributable to new leases entered into since the second quarter of 2003
for a new office in Cleveland, OH and larger offices in Edison, NJ and
Plattsburgh, NY.




                              INTEREST EXPENSE

Interest expense for the six months ended June 30, 2004 increased 8% to
$104,443 from $96,611 for the same period in 2003.  The increase in interest
expense was primarily due to an increase in the average outstanding balance on
the revolving loan and long-term debt when comparing the six months ended June
30, 2004 with the same period in 2003.


                                NET INCOME

The net loss for the six months ended June 30, 2004 was $71,151, or ($0.01)
per share basic and diluted compared to net income of 145,084, or $0.01 per
share basic and diluted, for the six months ended June 30, 2003.

               CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Management has identified the following critical accounting policies that
affect the Company's more significant judgments and estimates used in the
preparation of the Company's consolidated financial statements.  The
preparation of the Company's financial statements in conformity with
accounting principles generally accepted in the United States of America
requires the Company's management to make estimates and judgments that affect
the reported amounts of assets and liabilities, revenues and expenses, and
related disclosures of contingent assets and liabilities.  On an on-going
basis, management evaluates those estimates, including those related to long
lived assets, revenue recognition, valuation allowance on deferred tax
assets, allowance for doubtful accounts and contingencies and litigation. The
Company states these accounting policies in the notes to the consolidated
financial statements and in relevant sections in this discussion and analysis.
These estimates are based on the information that is currently available to
the Company and on various other assumptions that management believes to be
reasonable under the circumstances.  Actual results could vary from those
estimates.

The Company believes that the following critical accounting policies affect
significant judgments and estimates used in the preparation of its
consolidated financial statements:

Contracts are predominately short-term in nature (less than three months) and
revenue is recognized as costs are incurred and billed.  Income on long-term
fixed-priced contracts greater than three months is recognized on the
percentage-of-completion method.  Project costs are generally billed in the
month they are incurred and are shown as current assets.  Revenues recognized
in excess of amounts billed are recorded as an asset.  In the event interim
billings exceed costs and estimated profit, the net amount of deferred revenue
is shown as a current liability.  Estimated losses are recorded in full when
identified.

The Company maintains an allowance for doubtful accounts for estimated losses
resulting from the inability of its customers to make required payments, which
results in bad debt expense.  Management determines the adequacy of this
allowance by continually evaluating individual customer receivables,
considering the customer's financial condition, credit history and current
economic conditions.  If the financial condition of customers were to
deteriorate, resulting in an impairment of their ability to make payments,
additional allowances may be required.

The Company maintains a valuation allowance for deferred tax assets to reduce
these assets to their realizable amounts.  Recognition of these amounts and
the adjustment of the corresponding allowance is dependent on the generation
of taxable income in current and future years.  As circumstances change with
respect to managements expectations of future taxable income, the valuation
allowance is adjusted.

Item 3. Quantitative and Qualitative Disclosure About Market Risk.

There were no material changes in the Company's market risk or market risk
strategies during the quarter ended June 30, 2004.







                                     14.
<PAGE>



                  Item 4.  Controls and Procedures

(a)  Disclosure Controls and Procedures.
Within the 90 days before the date of this Form 10-Q, we evaluated the
effectiveness of the design and operation of our "disclosure controls and
procedures". OP-TECH conducted this evaluation under the supervision and with
the participation of management, including our Chief Executive Officer and
Chief Financial Officer.

      (i) Definition of Disclosure Controls and Procedures.
Disclosure controls and procedures are controls and other procedures that are
designed with the objective of ensuring that information required to be
disclosed in our periodic reports filed under the Exchange Act, such as this
report, is recorded, processed, summarized and reported within the time
periods specified in the SEC's rules and forms. As defined by the SEC, such
disclosure controls and procedures are also designed with the objective of
ensuring that such information is accumulated and communicated to our
management, including the Chief Executive Officer and Chief Financial Officer,
in such a manner as to allow timely disclosure decisions.

      (ii) Limitations on the Effectiveness of Disclosure Controls and
Procedures and Internal Controls.
OP-TECH recognizes that a system of disclosure controls and procedures (as
well as a system of internal controls), no matter how well conceived and
operated, cannot provide absolute assurance that the objectives of the system
are met. Further, the design of such a system must reflect the fact that there
are resource constraints, and the benefits of controls must be considered
relative to their costs. Because of the inherent limitations in all control
systems, no evaluation of controls can provide absolute assurance that all
control issues have been detected. These inherent limitations include the
realities that judgments in decision-making can be faulty, and that breakdowns
can occur because of simple error or mistake.  Additionally, controls can be
circumvented in a number of ways. Because of the inherent limitations in a
cost-effective control system, system failures may occur and not be detected.

      (iii) Conclusions with Respect to Our Evaluation of Disclosure Controls
and Procedures.
Subject to the limitations described above, our Chief Executive Officer and
Chief Financial Officer have concluded that our disclosure controls and
procedures are effective in timely alerting them to material information
relating to OP-TECH required to be included in OP-TECH's periodic SEC filings.

(b) Changes in Internal Controls.
There have been no significant changes in OP-TECH's internal controls or in
other factors that could significantly affect these controls subsequent to the
date of their evaluation.
