Explanatory Note

The purpose of this Amendment No. 1 on Form 10-K/A (the “Amendment”) is to amend Rockies Region 2007 Limited Partnership’s (the “Partnership’s” or “Registrant’s”) Part II, Item 9A(T), Controls and Procedures to fully comply with Rule 308(T) of Regulation S-K and to revise Part IV, Item 15, Exhibits−Exhibit 99.2 to comply with Item 1202(a)(8) of Regulation S-K.  This report amends the Partnership’s previously filed Annual Report on Form 10-K for the year ended December 31, 2009, filed with the Securities and Exchange Commission, or SEC, on March 31, 2010 (the “Original Form 10-K”).  Petroleum Development Corporation (“PDC”), which conducts business under the name PDC Energy, is the Managing General Partner of the Partnership.

The reasons for this amendment are more fully described below:

(1) The Partnership is revising the Original Form 10-K to include in this Amendment Item 9A(T)(b), Management’s Report on Internal Control Over Financial Reporting, which includes the Managing General Partner’s statement that the Partnership’s internal control over financial reporting was effective at December 31, 2009. Additionally, related disclosures that identify the framework used by the Managing General Partner to so evaluate the effectiveness of the Partnership’s internal controls, have been included in this Amendment.  This report was inadvertently omitted from the Original Form 10-K.

(2) The Partnership is filing a revised reserve report of the Partnership’s third-party petroleum engineering firm.  The report of Ryder Scott Company, L.P. (“Ryder Scott”) as of December 31, 2009 was included as Exhibit 99.2 to the Original Form 10-K.  The original report did not include the average price used in the annual reserves calculation and included a statement limiting the use of the report to Rockies Region 2007 Limited Partnership.  The report of Ryder Scott included as the Amendment’s Exhibit 99.2, now includes the average price used in the annual reserve calculation and does not contain any language limitation on the use of the report.

(3) New certifications on behalf of the Partnership by the Managing General Partner’s Chief Executive Officer and Chief Financial Officer are being filed as exhibits to this Amendment No. 1 on Form 10-K/A under Part IV, Item 15, Exhibits.

There are no other changes to the Original Form 10-K other than those outlined above. This Amendment does not reflect events occurring after the filing of the Original Form 10-K, nor does it modify or update disclosures therein in any way other than as required to reflect the amendment set forth in the following index and report sections included in this Amendment.

- 1 -

Item 9A (T). Controls and Procedures

The Partnership has no direct management or officers.  The management, officers and other employees that provide services on behalf of the Partnership are employed by the Managing General Partner.

2008 Material Weakness

As discussed in the Management’s Report on Internal Control Over Financial Reporting included in the Partnership’s 2008 Annual Report on Form 10-K, the Partnership did not maintain effective internal controls over financial reporting as of December 31, 2008, over transactions that are directly related to and processed by the Partnership, in that the Partnership failed to maintain sufficient documentation to adequately assess the operating effectiveness of internal control over financial reporting.  More specifically, the Partnership’s financial close and reporting narrative failed to adequately describe the process, identify key controls and assess segregation of duties.  This material weakness has been remediated as of December 31, 2009.

(a)  Evaluation of Disclosure Controls and Procedures

As of December 31, 2009, PDC, as Managing General Partner on behalf of the Partnership, carried out an evaluation, under the supervision and with the participation of the Managing General Partner's management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Partnership's disclosure controls and procedures pursuant to Exchange Act Rules 13a-15(e) and 15d-15(e).  This evaluation considered the various processes carried out under the direction of the Managing General Partner’s Disclosure Committee in an effort to ensure that information required to be disclosed by the Partnership in the SEC reports the Partnership files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Partnership’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

Based upon the evaluation, the Managing General Partner’s Chief Executive Officer and Chief Financial Officer concluded that the Partnership’s disclosure controls and procedures were effective as of December 31, 2009.

(b)  Management’s Report on Internal Control Over Financial Reporting

Management of PDC, the Managing General Partner of the Partnership, is responsible for establishing and maintaining adequate internal control over financial reporting.  Internal control over financial reporting is defined in Exchange Act Rules 13a-15(f) and 15d-15(f) as a process designed by, or under the supervision of, the issuer’s principal executive and principal financial officers, or persons performing similar functions, and effected by the issuer’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America and includes those policies and procedures that:

(1) Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the issuer;

(2) Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America and that receipts and expenditures of the issuer are being made only in accordance with authorizations of management and directors of the issuer; and

(3) Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the issuer’s assets that could have a material effect on the financial statements of the issuer.

- 2 -

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may deteriorate.

Management of the Managing General Partner has assessed the effectiveness of the Partnership’s internal control over financial reporting as of December 31, 2009, based upon the criteria established in “Internal Control - Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission.  Based on this evaluation, management of the Managing General Partner concluded that the Partnership maintained effective internal control over financial reporting as of December 31, 2009.

This 2009 Annual Report on Form 10-K does not include an attestation report of the Partnership’s independent registered public accounting firm regarding internal control over financial reporting pursuant to Item 308T(a)(4) of Regulation S-K.

(c)  Remediation of Material Weakness in Internal Control

PDC, the Managing General Partner, with participation from the Audit Committee of its Board of Directors, addressed the material weakness disclosed in the Partnership’s 2008 Annual Report on Form 10-K.  The Managing General Partner believes that the effective implementation of changes in internal controls over financial reporting outlined below remediated this known material weakness as of December 31, 2009.

The Partnership made the following changes in its internal control over financial reporting of the Partnership (as defined in Rules 13a-15(f) and 15d-15(f) of the Securities Exchange Act of 1934) during 2009.

· In the second quarter, the Partnership developed and implemented a plan to improve controls over certain key financial statement spreadsheets that support all significant balance sheet and income statement accounts.  The Partnership also created and documented a procedural framework to ensure the completeness and accuracy of the Partnership’s derivative activities.  Additionally, the Partnership has completed the development of a revised financial close and reporting narrative that adequately describes the process, identifies key controls and assesses segregation of duties.

· In the third quarter, the Partnership developed documentation that describes the business processes and identifies key controls for internal control over financial reporting that assisted the Managing General Partner in adequately assessing internal control over financial reporting for the Partnership.  In addition, the Partnership developed documentation and procedures to adequately assess segregation of duties.  The controls and procedures were tested prior to December 31, 2009.  At present, the Partnership has not quantified the total cost of this initiative; however, the majority of this cost is expected to be paid by the Managing General Partner.

(d)  Other Changes in Internal Control over Financial Reporting

During 2009, PDC made the following changes in PDC’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Securities Exchange Act of 1934) that have materially affected or are reasonably likely to materially affect the Partnership’s internal control over financial reporting:

· Effective July 1, 2009, as part of PDC’s broader financial reporting system, PDC implemented a new partnership investor distribution accounting module replacing the existing accounting software.  PDC has taken the necessary steps to monitor and maintain appropriate internal controls during this period of change.  These steps included procedures to preserve the integrity of the data converted and a review by the business owners to validate data converted.  Additionally, PDC provided training related to the business process changes and the financial reporting system software to individuals using the financial reporting system to carry out their job responsibilities, as well as those who rely on the financial information.  PDC anticipates that the implementation of this module will strengthen the overall systems of internal controls due to enhanced automation and integration of related processes.  PDC is modifying the design and documentation of internal control process and procedures relating to the new module to supplement and complement existing internal control over financial reporting.  The system changes were undertaken to integrate systems and consolidate information and were not undertaken in response to any actual or perceived deficiencies in PDC’s internal control over financial reporting.  Testing of the controls related to these new systems was included in the scope of PDC’s assessment of its internal control over financial reporting as of December 31, 2009.

The Managing General Partner continues to evaluate the ongoing effectiveness and sustainability of the changes PDC made in internal control over financial reporting, and as a result of the ongoing evaluation, may identify additional changes to improve internal control over financial reporting.  Further information regarding the material weakness of the Partnership referenced above may be found in the Partnership’s Annual Report on 10-K for the year ended December 31, 2008 under Item 9A(T), Controls and Procedures − Management’s Report on Internal Control Over Financial Reporting.
