The following constitutes Amendment No. 1 (this “Amendment”) to the initial Schedule 13D (the “Schedule 13D”) filed on June 12, 2015 by Matthew van Steenwyk (“Mr. Van Steenwyk”), Betty van Steenwyk (“Ms. Van Steenwyk”) and Arrow, LLC (“Arrow”, and together with Mr. Van Steenwyk and Ms. Van Steenwyk, the “Reporting Persons”). Except as specifically amended by this Amendment, the Schedule 13D remains in full force and effect.

Item 4.  Purpose of Transaction

The Reporting Persons may be deemed to have acquired beneficial ownership of 12,729,302 shares of common stock, $0.01 par value per share (the “Common Stock”), of American Power Group Corporation (the “Company”) pursuant to the Mr. Van Steenwyk’s position as manager (“Manager”) of Arrow and as trustee (“Trustee”) of the Betty Van Steenwyk Rollover IRA.

On April 30, 2012, the Company and a number of investor parties entered into a Securities Purchase Agreement (the “Series A Agreement”). In connection with this arrangement, the investors received preferred stock and warrants exchangeable for Common Stock, and the Company duly filed a Certificate of Designation with the state. Arrow subsequently acquired additional preferred units of the Company and warrants exchangeable for Common Stock of the Company on November 26, 2014 when the Company entered into a second and substantially similar Securities Purchase Agreement (the “Series B Agreement”). Pursuant to Section 6(d) of both Certificates of Designation filed in connection with the agreements and to Section 2(e) of each warrant issued in conjunction with the transaction, certain beneficial ownership limitations relating to the ownership of shares of Common Stock could be increased.

The Reporting Persons do not desire to be subject to any such limitations, and with respect to the limitations set forth in Section 6(d) of the Certificates of Designation and  Section 2(e) of each warrant, the Reporting Persons have elected to increase the beneficial ownership limitation threshold set forth in the aforementioned documents to one hundred percent (100%) of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon conversion of both series of preferred stock and the exercise of all warrants issued as part of those two series of transactions.

In addition to the preferred stock and warrants to purchase shares of Common Stock, Mr. Van Steenwyk has entered into multiple agreements pursuant to which he acquired additional shares of Common Stock of the Company. Arrow has not made a direct purchase of Common Stock, but has been issued shares of Common Stock by the Company in payment of certain dividends on the Series B 10% Convertible Preferred Stock, par value $1.00 per share, of the Company. Arrow has, however, recently entered into agreements to purchase both additional warrants exchangeable for shares of Company Common Stock and shares of Series A 10% Convertible Preferred Stock, par value $1.00 per share, of the Company.

Item 5.   Interest in Securities of the Issuer

(a)-(b)  As determined pursuant to Rule 13d-3 under the Exchange Act (based on 51,133,556 shares of Common Stock issued and outstanding as represented by the Company on the Company’s Form 10-Q/A for the quarterly period ended December 31, 2014):

(i) When both shares over which he has shared power and sole power are taken into account, Mr. Van Steenwyk is deemed to beneficially own 12,729,302 shares of Common Stock, which constitutes approximately 21.7% of the issued and outstanding Common Stock of the Company.

(ii) Ms. Van Steenwyk beneficially owns 1,000 Shares, representing in the aggregate less than 1% of the issued and outstanding Shares, and shares both voting and dispositive power with respect to all 1,000 shares with Mr. Van Steenwyk.

(iii) Arrow, LLC beneficially owns 7,657,139 Shares, representing in the aggregate approximately 13.1% of the issued and outstanding Shares of the Company, and shares power with Mr. Van Steenwyk to vote and dispose of all 7,657,139 Shares.

(c)  Since June 2, 2015, the Reporting Persons have not effected any transactions with respect to Shares of the Company.

(d)  To the knowledge of the Reporting Persons, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Common Stock herein described.

(e)  Not applicable.

Except as set forth in this Schedule 13D, no shares of Common Stock are beneficially owned by the Reporting Persons, or to the knowledge of the Reporting Persons, any person listed on Schedule A to this Schedule 13D.

Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Other than as described in Items 4 and 5, which are incorporated herein by reference, and in the agreements and documents attached as exhibits hereto or incorporated herein by reference, to the knowledge of the Reporting Persons, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 or between such persons and any other person with respect to any securities of the Company, including but not limited to transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies, the existence of which would give another person voting or investment power over the securities of the Company.
