Item 1.   Description of Proposed Transaction.

          National Fuel Resources, Inc. ("NFR") and Leidy Hub, Inc. 

("Leidy") are wholly-owned subsidiaries of National Fuel Gas Company 

("National").  National is a public utility holding company 

registered under the Public Utility Holding Company Act of 1935, as 

amended ("Act").  Neither National, nor any of the subsidiaries of 

National other than NFR and Leidy, join in this Post-Effective 

Amendment to the Application-Declaration on file in this proceeding.

          A.    Background.

          NFR has undertaken the following transactions and 

activities as authorized by the Commission in HCAR No. 35-25437:  

          (1) NFR has been and continues to be engaged in the 

business of marketing natural gas and related activities.

          (2) NFR entered into a partnership with Citizens Gas Supply 

Corporation ("Citizens Gas").  The name of the partnership was 

Citizens National Gas Co. ("Partnership").  

          (3) The Partnership engaged in purchasing, storing, 

transporting and marketing natural gas and the acquisition of related 

assets.

          (4) NFR has been and continues to participate in the 

National Fuel System Money Pool ("Money Pool").  NFR may make 

borrowings from the Money Pool in a maximum principal amount at any 

one time outstanding of $15 million through December 31, 1995 

pursuant to HCAR No. 35-25964.

          Additionally, pursuant to HCAR No. 35-25437, NFR was 

authorized to make available to the Partnership, through December 31, 

1991, one or more loans aggregating up to $10 million.  NFR 

requested this authority so that the Partnership could invest in "any 

and all physical assets, and any and all associated contracts and 

property interests attendant thereto, for use in connection with 

gathering, transportation, distribution or marketing of natural gas 

which it would consider taking for itself, and which is consistent 

with, or is a natural and reasonable extension of, its business as it 

existed just prior to the closing date" (hereinafter referred to as 

"Marketing Related Investments") (See pp. 8 - 9 of Form U-1, 

Amendment No. 3, File No. 70-7833).  The funds for these loans to the 

Partnership were to be derived from NFR Money Pool borrowings and 

working capital.  No loans are outstanding between the Partnership 

and NFR.

          On October 28, 1993, NFR filed the Seventh Certificate 

Pursuant to Rule 24 in regard to this file No. 70-7833, HCAR No. 

35-25437, informing the Commission that during the quarter ended 

September 30, 1993, NFR and Citizens National Gas Company had 

completed the sale of substantially all of the Partnership assets.  

Thereafter, the Partnership was wound up and dissolved(1).


________________________

(1)  Neither NFR nor any of its affiliates sought approval to sell 
the Partnership assets and dissolve the Partnership because it was 
determined that no such approval was necessary under the Act.  
Section 9(a) was deemed not to be applicable because that section 
covers the acquisition but not the sale of a security or an interest 
in a business.  Additionally, the Partnership assets were not utility 
assets, so that, Section 12(d) was also inapplicable.  
          B.  Proposed Transactions.

          (1)  NFR proposes to make Marketing Related Investments 

through borrowings by NFR from the Money Pool up to the then current 

maximum amount of borrowings that NFR is authorized to make from the 

Money Pool, which is currently $15 million in the aggregate.  It is 

anticipated tht the majority of these marketing related investments 

will entail the purchase of gas reserves, gas pipelines and 

appurtenant property.

          (2)  NFR proposes to take assignment from Leidy of certain 

research and development investments at book value as described 

below(2).  

                (i)  One of the investments which would be assigned 

from Leidy to NFR is Leidy's investment in Metscan, Inc. ("Metscan").  

Metscan developed a low cost and efficient electronic automatic meter 

reading device ("AMD"), that provides an economical and efficient 

method of reading residential natural gas utility meters.  The AMD is 

a microprocessor which is affixed to a gas meter and which 

accumulates and stores information regarding natural gas usage by a 

customer and transmits it by telephone line to a computer.  This 

information is then available for billing purposes.  The Metscan 

system, i.e., the attachment of the AMD to a gas meter, and its 

________________________


(2)   As reported in a Certificate Pursuant to Rule 24 filed on 
      January 24, 1994, Enerop Corporation has changed its name to 
      Leidy Hub, Inc. ("Leidy").  Leidy will focus on marketing hub 
      activities which is more fully explained in a separate U-1 
      filing which is being filed contemporaneously with this 
      Amendment.  

connection by telephone line to a computer (i) improves meter reading 

efficiency, as accurate readings can be received electronically, (ii) 

enhances meter security and theft detection, because actual 

consumption data is phoned in monthly (or possibly daily) and the AMD 

has a tamper alarm, and (iii) enhances consumption monitoring by the 

ability to provide daily consumption data.  As noticed in HCAR No. 

35-26023 issued April 8, 1994, Leidy has proposed through 

Post-Effective Amendment No. 13 to File No. 70-7201 to acquire 29, 

167 shares of Metscan Class B Preferred Stock, $.01 par value, 

("Class B Preferred"), out of a total number of 2,736,667 shares to 

be sold, for $35,000 ($1.20 per share).  Once the proposed 

transaction has been consummated, Leidy will own 7.31% of Metscan's 

common stock, 9.83% of the Metscan Class A Preferred Stock and 1.07% 

of the Class B Preferred, or about 5.52% of the actual and potential 

equity investment in Metscan and Leidy's total investment in Metscan 

will be $1,261,000.00.  All of Leidy's interest in Metscan will be 

transferred to NFR at book value.

          (3) NFR also seeks authorization to accept assignment of 

the Agreement dated October 1, 1993, between Leidy (then Enerop) and 

Perfection Corporation attached as Exhibit A-8 (the "Perfection 

Agreement") regarding research, development and marketing of 

polyethylene ball valves ("Valves") for polyethylene fuel gas piping 

systems ("Perfection Valve Development Program").  Under the 

Perfection Agreement, Leidy (then Enerop) pays an aggregate of 

$610,000.00 in return for a royalty of three percent (3%) of the net 

revenue from the sale of the Valves ("Royalty") up to a 16% return on 

investment(3).  Perfection is a manufacturing company with its 

principal place of business in Madison, Ohio.  Perfection is not an 

affiliate of National or any of National's subsidiaries.  It is 

anticipated that the Valves will be marketed and sold throughout the 

United States with a significant percentage of such sales occurring 

within National's system.  A condition subsequent to the Perfection 

Agreement is that Leidy (then Enerop) receive SEC approval under the 

Act, if it is determined that such approval is necessary. 

                NFR hereby seeks authority to accept assignment of 

the Perfection Agreement from Leidy and to undertake the obligations 

and rights thereunder, including the obligation to make the aggregate 

$610,000.00 investment and the right to receive the Royalty.  The 

Perfection investment constitutes "[t]he acquisition by a registered 

company of an interest in a company organized to participate in 

activities related to the supply of natural gas."  Thus, pursuant to 

Section 2(b) of the Gas Related Activities Act of 1990 ("GRAA") the 

Perfection investment will meet the requirement of Section 11(b) of 

the Act that it be reasonably incidental or economically necessary or 

appropriate to the operation of the utility (i.e., National Fuel Gas 

Distribution Corporation ("Distribution")) provided the Perfection 

________________________

(3)   The Perfection Agreement covers three separate valve research 
      and development programs.  Enerop invested $125,000.00 in the 
      1-1/4" Program and $85,000.00 in the 2" Program.  These programs 
      have been rolled up into the Perfection Agreement along with 
      the new 3-4-6" Program.  The $400,000.00 investment in the 
      3-4-6" Program contemplated in the Perfection Agreement will be 
      made by NFR upon SEC approval of this Amendment.
investment is in the interest of the consumers of Distribution or the 

consumers of any other subsidiary of National.

          Plastic piping has been shown to be superior to traditional 

metal piping in regard to durability, leak resistance, ease of 

installation, etc.  It is anticipated that the various plastic Valves 

developed as a result of the Perfection Research and Development 

Program will also be superior to metal ones in these respects.  

Additionally, its anticipated that in many instances plastic Valves 

will be installed in a pipeline system that is otherwise already all 

plastic.  In such circumstances the need for cathodic protection will 

be eliminated since no corrosion will occur within an all plastic 

system.  Distribution's consumers will benefit from the development 

of these Valves because the utility will experience lower operations 

and maintenance costs, thus helping to keep rates from rising.

          B.2  Future Planned Activities

          NFR also plans in the future to finance or invest in and 

provide consulting services to (i) research and development projects 

related to the gas industry, (ii) qualifying co-generation facilities 

as defined in the Public Utility Regulatory Policies Act of 1978 

("PURPA"), (iii) qualifying small production facilities as defined in 

PURPA, (iv) exempt wholesale generators within the meaning of Section 

32 of the Act, and (v) foreign utility companies ("FUCOs") within the 

meaning of Section 33 of the Act.  NFR will file for any required 

authorization prior to undertaking any investment in or financing of 

any research and development project, independent power project or 

foreign utility company and no such authorization is currently being 

sought.

Item 3.   Applicable Statutory Provisions.


          Sections 9(a), 10, 12(b), 32 and 33 and Rules 23, 24, 43

transactions contemplated hereunder.

          Applicable Provisions      Proposed Transaction

          Section 12(b)              NFR's investment in Marketing 
          Rule 45                    Related Investments through 
                                     borrowings from the National 
                                     Money Pool.

          Sections 9(a) and 10,      Assignment of Leidy's Interest
          Rules 23 and 43,           in Metscan, Inc. to NFR at Book
          Section 2(b) of the GRAA   Value.

          Sections 9(a), 10, and     Assignment of the Perfection
          12(b), Rules 23 and 43     Agreement to NFR from Leidy at
          Section 2(b) of the GRAA   Book Value and Assumption of
                                     Obligations thereunder.

          To the extent that the proposals herein are considered by 

the SEC to require authorization, approval or exemption under any 

section of the Act or provision of the rule or regulations other than 

those specifically referred to herein, request for such authorization 

approval or exemption is hereby made.


Item 4.

          No federal regulatory authority, other than the SEC, has 

jurisdiction over the proposals.  No state regulatory authority has 

jurisdiction over the proposed transactions.


Item 5.   Procedure

          The SEC is requested to issue an order permitting the 

Application-Declaration to become effective as soon as possible with 

respect to consummation of the transactions described herein.

          National respectfully requests that the SEC's orders herein 

be entered pursuant to the provisions of Rule 23.  If a hearing is 

ordered, Applicant-Declarants waive a recommended decision by a 

hearing officer, or any other responsible officer of the SEC, and 

agree that the Division of Investment Management, Office of Public 

Utility Regulation may assist in the preparation of the SEC's 

decision and/or order; and request that the SEC's order become 

effective upon issuance.

          The Applicants hereby request that certain information 

contained in the Exhibits hereto, as indicated in Item 6 Exhibits 

(the "Information") be kept confidential pursuant to Rule 104(b) 

(Section 250.104(b) of the Commission's Regulations).

          Public disclosure of the Information is not necessary or 

appropriate in the public interest or for the protection of investors 

or consumers.  

          The Information includes a projection of NFR's internal 

rate of return on the Perfection investment which contains projected 

sales volumes and selling price per unit for each Valve.  Also 

included in the Information are Marketing Studies prepared by 

Perfection in regard to each Valve which describe market 

opportunities on a regional basis, competitors and their products, 

possible competitive responses to introduction of the Perfection 

Valves and features which the Valves must contain to be competitive. 

          All of this information would be highly coveted by 

Perfection's competitors (and otherwise unavailable) and if disclosed 

would put Perfection's Valve programs at a significant competitive 

disadvantage given that competitors are not required to make public 

their marketing studies and information.  Additionally, the amount of 

the Perfection investment ($610,000.00) is of an order of magnitude 

too small to be material to either investors or consumers.  

          The investing and consuming public would be best served by 

allowing the Information to remain confidential, thereby allowing 

Perfection to compete on an equal basis with its competitors.


Item 7.   

          The proposed transactions outlined herein involve no action 

which will significantly affect the quality of the environment.

          No federal agency has prepared or is preparing an 

environmental impact statement with respect to the transactions 

proposed in the Application-Declaration.

                             SIGNATURES

          Pursuant to the requirements of the Public Utility Holding 

Company Act of 1935, the undersigned companies have duly caused this 

Amendment to the application-declaration to be signed on their behalf
