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 September 30,
2000.

Item 2.  Description of Business

The Partnership has placed 54.66 net wells in production in the
Clinton/Medina formation in Mercer and Lawrence Counties, Pennsylvania and
Stark and Trumbull Counties, Ohio.  As of September 30, 2000, all 54.66 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 $871,243 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 drilling funds will be required.

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.  Management does not anticipate that the Partnership will
need to borrow.  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 September 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.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  ATLAS-ENERGY FOR THE NINETIES-PUBLIC #8 LTD.

Management's discussion and analysis should be read in conjunction with the
financial statements and notes thereto.

RESULTS OF OPERATIONS

NINE MONTHS ENDED SEPTEMBER 30, 2000

The Partnership commenced production in January, 2000.  Natural gas sales
revenue for the nine months ended September 30, 2000 amounted to $1,640,559
based on gas production of 587,319 Mcf.  The average sales price for gas
production during this period was $3.09/Mcf.

THREE MONTHS ENDED SEPTEMBER 30, 2000

Natural gas sales revenue for the three months ended September 30, 2000
amounted to $871,243 based on gas production of 282,830 Mcf. The average
sales price for gas production during this period was $3.36/Mcf.

FINANCIAL CONDITION

LIQUIDITY

The initial distribution to partners was made during the second quarter of
2000.  The Partnership's working capital increased from $(15,003) at December
31, 1999 to $783,099 at September 30, 2000. The increase is attributable to
natural gas production during the current quarter, 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.
