Item 1.  Financial Statements

The unaudited Financial Statements of Atlas-Energy for the Nineties-Public #8
Ltd.  (the "Partnership") for the period January 1, 2000 to June 30, 2000.

Item 2.  Description of Business

The Partnership has placed 118 net wells in production in the Clinton/Medina
formation in Mercer and Lawrence Counties, Pennsylvania and Stark and Trumbull
Counties, Ohio. As of June 30, 2000, all 118 net wells are in production. The
first quarterly distribution was made in June 2000 for natural gas production
during January, February, March, 2000.

Net Production revenue for the three months was $630,422 which includes
landowners royalties. Expenses for this period include $75.00 per month per well
for administrative costs and $275.00 per month per well for pumpers fees.

For the next twelve months management believes that the Partnership has adequate
capital. No other wells will be drilled and, therefore, no additional funds will
be required.

Although management does not anticipate that the Partnership will have to do so,
any additional funds which may be required will be obtained from production
revenues from Partnership wells or from borrowings by the Partnership from Atlas
or its affiliates, although Atlas is not contractually committed to make such a
loan. No borrowings will be obtained from third parties.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

                  ATLAS-ENERGY FOR THE NINETIES--PUBLIC #8 LTD.
                       A PENNSYLVANIA LIMITED PARTNERSHIP




1.       INTERIM FINANCIAL STATEMENTS

         The financial statements as of June 30, 2000 and for the three months
then ended have been prepared by the management of the Partnership without
audit, pursuant to the rules and regulations of the Securities and Exchange
Commission. Certain information and footnote disclosures normally included in
the financial statements prepared in accordance with generally accepted
accounting principles have been omitted pursuant to such rules and regulations,
although the partnership believes that the disclosures are adequate to make the
information presented not misleading. These financial statements should be read
in conjunction with the audited December 31, 1999 financial statements. In the
opinion of management, all adjustments (consisting of only normal recurring
accruals) considered necessary for presentation have been included.

2.       SIGNIFICANT ACCOUNTING POLICIES

         The Partnership uses the successful efforts method of accounting for
oil and gas activities. Costs to acquire mineral interests in oil and gas
properties and drill and equip wells are capitalized. Oil and gas properties are
periodically assessed and when unamortized costs exceed expected future net cash
flows, a loss is recognized by a charge to income.

         Capitalized costs of oil and gas wells and leases are depreciated,
depleted and amortized by the unit of production method.

RESULTS OF OPERATIONS

SIX MONTHS ENDED JUNE 30, 2000

The Partnership commenced production in January, 2000. Natural gas sales revenue
for the six months ended June 30, 2000 amounted to $769,316 based on gas
production of 304,489 Mcf. The average sales price for gas production during
this period was $2.82/Mcf.

THREE MONTHS ENDED JUNE 30, 2000

Natural gas sales revenue for the three months ended June 30, 2000 amounted to
$630,422 based on gas production of 244,649 Mcf. The average sales price for gas
production during this period was $2.87/Mcf.


FINANCIAL CONDITION

LIQUIDITY

There was one cash payment to the Partnership from the initial production from
the wells in this program and one distribution to investors during the three
months ended June 30, 2000. The Partnership's working capital increased from
$(15,003) at December 31, 1999 to $545,668 at June 30, 2000. The increase is
attributable to the commencement of natural gas production for new wells turned
on-line during the first half of the year, which resulted in higher receivables
in connection with sales of gas produced.

CAPITAL RESOURCES

There were no new material commitments for capital expenditures during
the period and the Partnership does not expect any in the foreseeable future.
