C. General Provisions for Use and Surrender of NO x Allowances.
70. Except as may be necessary to comply with this Section and Section XIII (Stipulated Penalties), Defendants may not use NO x Allowances to comply with any requirement of this Consent Decree, including by claiming compliance with any emission limitation or Eastern System-Wide Annual Tonnage Limitation required by this Decree, by using, tendering,

22or otherwise applying NO x Allowances to achieve compliance or offset any emissions above the limits specified in this Consent Decree.
71. As required by this Section IV of this Consent Decree, Defendants shall surrender
NO x Allowances that would otherwise be available for sale, trade, or transfer as a result of actions taken by Defendants to comply with the requirements of this Consent Decree.
72. NO x Allowances allocated to the AEP Eastern System may be used by Defendants to meet their own federal and/or st ate Clean Air Act regulatory requirements for the Units included in the AEP Eastern System. Subject to Paragraph 70, nothing in this Consent Decree shall prevent Defendants from purchasing or otherwise obtaining NO x Allowances from another source for purposes of complying with their own federal and/or state Clean Air Act requirements to the extent otherwise allowed by law.
73. The requirements in this Consent Decree pertaining to Defendants’ use and surrender of NO x Allowances are permanent injunctions not subject to any termination provision of this Consent Decree. These provisions shall survive any termination of this Consent Decree.
D. Use of Excess NO x Allowances.
74. Calculation of Unrestricted and Restricted NO x Allowances. On an annual basis, beginning in 2009, Defendants shall calculate the difference between the NO x CAIR Allocations for the Units in the AEP Eastern System for that year and the annual Eastern System-Wide Tonnage Limitations for NO x for that calendar year. This difference represents the total Excess
NO x Allowances for that calendar year. For purposes of this Consent Decree, for each year commencing in 2009 and ending in 2015, forty-two percent (42%) of the Excess NO x Allowances shall be Unrestricted Excess NO x Allowances and fifty-eight percent (58%) shall be

23Restricted Excess NO x Allowances. Commencing in 2016, and continuing thereafter, all Excess
NO x Allowances shall be Restricted Excess NO x Allowances. 75. Use and Surrender of Unrestricted Excess NO x Allowances. For each calendar year commencing in 2009 and ending in 2015, Defendants may use Unrestricted Excess NO x Allowances in any manner authorized by law. No later than March 1, 2016, Defendants must surrender, or transfer to a non-profit third party selected by Defendants for surrender, all unused Unrestricted Excess NO x Allowances subject to surrender accumulated during the period from 2009 through 2015.
76. Use and Surrender of Restricted Excess NO x Allowances. Beginning in calendar year 2009, and for each calendar year thereafter, Defendants shall calculate the difference between the number of any Restricted Excess NO x Allowances and the number of NO x Allowances that is equal to the amount of actual NO x emissions from: (a) any New and Newly Permitted Unit as defined in this Consent Decree, and (b) the following five natural-gas plants but only up to a cumulative total of 1200 tons of NO x in any single year: Ceredo Generating Station located near Ceredo, West Virginia, with a nominal generating capacity of 505 megawatts; Waterford Energy Center located in southeastern Ohio, with a nominal generating capacity of 821 megawatts; Darby Electric Generating Station located near Columbus, Ohio, with a nominal generating capacity of 480 megawatts; Lawrenceburg Generating Station located in Lawrenceburg, Indiana, with a generating capacity of 1,096 megawatts; and a natural gas-fired power plant under construction near Dresden, Ohio, with a nominal generating capacity of 580 megawatts. This difference shall be the amount of Restricted Excess NO x Allowances

24potentially subject to surrender in 2016. During calendar years 2009 through 2015, Defendants may accumulate Restricted Excess NO x Allowances potentially subject to surrender in 2016.
77. NO x Allowances from Renewable Energy. Beginning in calendar year 2009, and for each calendar year thereafter, Defendants may subtract from the number of Restricted Excess
NO x Allowances potentially subject to surrender, a number of allowances calculated in accordance with this Paragraph. To calculate such number, Defendants shall use the following method: multiply 0.0002 by the sum of (a) the actual annual generation in MWH/year generated from solar or wind power projects first owned or operated by Defendants after the Date of Lodging of this Consent Decree, and (b) the actual annual generation in MWH/year purchased by Defendants from solar or wind power projects in any year after the Date of Lodging of this Consent Decree. Such figure so calculated shall be subtracted from the number of Restricted
Excess NO x Allowances potentially subject to surrender each year. The remainder shall be the Restricted Excess NO x Allowances subject to surrender.
78. Defendants may, solely at their discretion, use Restricted Excess NO x Allowances at a New and Newly Permitted Unit for which Defendants have received a final NSR Permit from the permitting agency even if the NSR Permit has been appealed but not stayed during the permit appeal process. If Defendants use Restricted Excess NO x Allowances at such New and Newly Permitted Unit, and the emissions from such New and Newly Permitted Unit are greater than what such Unit is permitted to emit after final adjudication of the appeal process, Defendants shall, within thirty (30) days of such final adjudication, retire an amount of NO x Allowances equal to the number of tons of NO x actually emitted that exceeded the finally adjudicated permit limit.

2579. No later than March 1, 2016, the total number of Restricted Excess NO x Allowances subject to surrender accumulated during 2009 through 2015 as calculated in accordance with Paragraphs 74, 76, and 77, shall be surrendered or transferred to a non-profit third party selected by Defendants for surrender, pursuant to Subsection F, below. Beginning in calendar year 2016, and for each calendar year thereafter, the total number of Restricted Excess
NO x Allowances subject to surrender for that year calculated in accordance with Paragraph 74, 76 and 77, shall be surrendered, or transferred to a non-profit third party selected by Defendants for surrender, by March 1 of the following calendar year.
E. Super-Compliant NO x Allowances.
80. In each calendar year beginning in 2009, and continuing thereafter, Defendants may use in any manner authorized by law any NO x Allowances made available in that year as a result of maintaining actual NO x emissions from the AEP Eastern System below the Eastern System-Wide Annual Tonnage Limitations for NO x under this Consent Decree for each calendar year. Defendants shall timely report the generation of such Super-Compliant NO x Allowances in accordance with Section XI (Periodic Reporting) and Appendix B of this Consent Decree.
F. Method for Surrender of Excess NO x Allowances.
81. For purposes of this Consent Decree, the “surrender” of Excess Restricted or Unrestricted Excess NO x Allowances subject to surrender means permanently surrendering to
EPA NO x Allowances from the accounts administered by EPA so that such NO x Allowances can never be used thereafter to meet any compliance requirement under the Clean Air Act, a state implementation plan, or this Consent Decree.

2682. For all Restricted or Unrestricted Excess NO x Allowances subject to surrender required to be surrendered to EPA in Paragraphs 79 and 75, above, Defendants or the third party recipient(s) (as the case may be) shall first submit a NO x Allowance transfer request form to EPA’s Office of Air and Radiation’s Clean Air Ma rkets Division directing the transfer of such
NO x Allowances to the EPA Enforcement Surrender Account or to any other EPA account that EPA may direct in writing. As part of submitting these transfer requests, Defendants or the third party recipient(s) shall irrevocably authorize the transfer of these NO x Allowances and identify – by name of account and any applicable serial or other identification numbers or station names – the source and location of the NO x Allowances being surrendered.
83.

107. Defendants shall install, calibrate, operate, and maintain PM CEMS, as specified below. Each PM CEMS shall comprise a continuous particle mass monitor measuring particulate matter concentration, directly or indirectly, on an hourly average basis and a diluent monitor used to convert the concentration to units of lb/mmBTU. Defendants shall maintain, in an electronic database, the hourly average emission values produced by all PM CEMS in lb/mmBTU. Defendants shall use reasonable efforts to keep each PM CEMS running and producing data whenever any Unit served by the PM CEMS is operating.
108. No later than December 31, 2011, Defendants shall submit to EPA pursuant to Section XII (Review and Approval of Submittals) of this Consent Decree: (a) a plan for the installation and certification of each PM CEMS, and (b) a proposed Quality Assurance/Quality Control (“QA/QC”) protocol that shall be followed in calibrating such PM CEMS. In developing both the plan for installation and certification of the PM CEMS and the QA/QC protocol, Defendants shall use the criteria set forth in 40 C.F.R. Part 60, Appendix B, Performance Specification 11, and Appendix F, Procedure 3. Following approval by EPA of the protocol, Defendants shall thereafter operate each PM CEMS in accordance with the approved protocol. 109.

After two (2) years of operation, Defendants may attempt to demonstrate that it is infeasible to continue operating PM CEMS. As part of such demonstration, Defendants shall submit an alternative PM monitoring plan for review and approval by EPA. The plan shall explain the basis for stopping operation of the PM CEMS and propose an alternative PM monitoring plan. If the United States disapproves the alternative PM monitoring plan, or if the United States rejects Defendants’ claim that it is infeasible to continue operating PM CEMS, such disagreement is subject to Section XV (Dispute Resolution).
113. “Infeasible to Continue Operating PM CEMS” Standard. Operation of a PM CEMS shall be considered no longer feasible if: (a) the PM CEMS cannot be kept in proper 39condition for sufficient periods of time to produce reliable, adequate, or useful data consistent with the QA/QC protocol, or (b) Defendants de monstrate that recurring, chronic, or unusual equipment adjustment or servicing needs in relation to other types of continuous emission monitors cannot be resolved through reasonable expenditures of resources. If EPA determines that Defendants have demonstrated pursuant to this Paragraph that operation is no longer feasible, Defendants shall be entitled to discontinue operation of and remove the PM CEMS.
114. PM CEMS Operations Will Continue During Dispute Resolution or Proposals for Alternative Monitoring. Until EPA approves an alternative monitoring plan, or until the conclusion of any proceeding under Section XV (D ispute Resolution), Defendants shall continue to operate the PM CEMS.

Defendants shall pay all stipulated penalties to the United States within thirty (30) days of receipt of written demand to Defendants from the United States, and shall continue to make such payments every thirty (30) days thereafter until the violation(s) no longer continues, unless Defendants elect within twenty (20) days of receipt of written demand to Defendants from the United States to dispute the accrual of stipulated penalties in accordance with the provisions in Section XV (Dispute Resolution) of this Consent Decree. 154. Stipulated penalties shall continue to accrue as provided in accordance with Paragraph 152 during any dispute, with interest on accrued stipulated penalties payable and calculated at the rate established by the Secretary of the Treasury, pursuant to 28 U.S.C. § 1961, but need not be paid until the following:

a. If the dispute is resolved by agreement, or by a decision of Plaintiffs pursuant to Section XV (Dispute Resolution) of this Consent Decree that is not appealed to the Court, accrued stipulated penalties agreed or determined to be owing, together with accrued interest, shall be paid within thirty (30) days of the effec tive date of the agreement or of the receipt of Plaintiffs’ decision; b. If the dispute is appealed to the Court and Plaintiffs prevail in whole or in part, Defendants shall, within sixty ( 60) days of receipt of the Court’s decision or order, pay all accrued stipulated penalties determined by the Court to be owing, together with interest accrued on such penalties determined by the Court to be owing, except as provided in Subparagraph c, below;

59c. If the Court’s decision is appealed by any Party, Defendants shall, within fifteen (15) days of receipt of the final appellate court decision, pay all accrued stipulated penalties determined to be owing, together with interest accrued on such stipulated penalties determined to be owing by the appellate court. Notwithstanding any other provision of this Consent Decree, the accrued stipulated penalties agreed by the Plaintiffs and Defendants, or determined by the Plaintiffs through Dispute Resolution, to be owing may be less than the stipulated penalty amounts set forth in Paragraph 150. 155. All stipulated penalties shall be paid in the manner set forth in Section IX (Civil Penalty) of this Consent Decree. 156. Should Defendants fail to pay stipulated penalties in compliance with the terms of this Consent Decree, the United States shall be entitled to collect interest on such penalties, as provided for in 28 U.S.C. § 1961. 157. The stipulated penalties provided for in this Consent Decree shall be in addition to any other rights, remedies, or sanctions availa ble to Plaintiffs by reason of Defendants’ failure to comply with any requirement of this Consent Decree or applicable law, except that for any violation of the Act for which this Consent Decree provides for payment of a stipulated penalty, Defendants shall be allowed a credit for stipulated penalties paid against any statutory penalties also imposed for such violation.

60XIV. FORCE MAJEURE 158. For purposes of this Consent Decree, including, but not limited to, Paragraphs 67 and 86, a “Force Majeure Event” shall mean an event that has been or will be caused by circumstances beyond the control of Defendants or any entity controlled by Defendants that delays compliance with any provision of this C onsent Decree or otherwise causes a violation of any provision of this Consent Decree despite Defendants’ best efforts to fulfill the obligation. “Best efforts to fulfill the obligation” include using best efforts to anticipate any potential Force Majeure Event and to address the effects of any such event (a) as it is occurring and (b) after it has occurred, such that the delay or violation is minimized to the greatest extent possible. 159. Notice of Force Majeure Events. If any event occurs or has occurred that may delay compliance with or otherwise cause a violation of any obligation under this Consent Decree, as to which Defendants intend to assert a claim of Force Majeure, Defendants shall notify the Plaintiffs in writing as soon as practicable, but in no event later than twenty-one (21) business days following the date Defendants first knew, or by the exercise of due diligence should have known, that the event caused or may cause such delay or violation. In this notice, Defendants shall reference this Paragraph of this Consent Decree and describe the anticipated length of time that the delay or violation may persist, the cause or causes of the delay or violation, all measures taken or to be taken by Defendants to prevent or minimize the delay or violation, the schedule by which Defendants propose to implement those measures, and Defendants’ rationale for attributing a delay or violation to a Force Majeure Event. Defendants shall adopt all reasonable measures to avoid or minimize such delays or violations. Defendants shall be deemed to know of any circumstance which Defendants or any entity controlled by Defendants knew or should have known. 61160. Failure to Give Notice. If Defendants materially fail to comply with the notice requirements of this Section, the Plaintiffs may void Defendants’ claim for Force Majeure as to the specific event for which Defendants have failed to comply with such notice requirement.
161. Plaintiffs’ Response. The Plaintiffs shall notify Defendants in writing regarding Defendants’ claim of Force Majeure as soon as reasonably practicable. If the Plaintiffs agree that a delay in performance has been or will be caused by a Force Majeure Event, the Parties shall stipulate to an extension of deadline(s) for performance of the affected compliance requirement(s) by a period equal to the delay actually caused by the event, or the extent to which Defendants may be relieved of stipulated penalties or other remedies provided under the terms of this Consent Decree. Such agreement shall be reduced to writing, and signed by all Parties. If the agreement results in a material change to th e terms of this Consent Decree, an appropriate modification shall be made pursuant to Section XXII (Modification). If such change is not material, no modification of this Consent Decree shall be required.
162. Disagreement. If Plaintiffs do not accept Defenda nts’ claim of Force Majeure, or if the Plaintiffs and Defendants cannot agree on the length of the delay actually caused by the Force Majeure Event, or the extent of relief required to address the delay actually caused by the Force Majeure Event, the matter shall be resolved in accordance with Section XV (Dispute Resolution) of this Consent Decree.
163. Burden of Proof. In any dispute regarding Force Majeure, Defendants shall bear the burden of proving that any delay in performan ce or any other violation of any requirement of this Consent Decree was caused by or will be caused by a Force Majeure Event. Defendants shall also bear the burden of proving that Defendants gave the notice required by this Section and the burden of proving the anticipated duration and extent of any delay(s) attributable to a 62Force Majeure Event. An extension of one compliance date based on a particular event may, but will not necessarily, result in an extension of a subsequent compliance date.
164. Events Excluded . Unanticipated or increased costs or expenses associated with the performance of Defendants’ obligations under this Consent Decree shall not constitute a Force Majeure Event. 165. Potential Force Majeure Events. The Parties agree that, depending upon the circumstances related to an event and Defendants’ response to such circumstances, the kinds of events listed below are among those that could qualify as Force Majeure Events within the meaning of this Section: construction, labor, or equipment delays; Malfunction of a Unit or emission control device; unanticipated coal supply or pollution control reagent delivery interruptions; acts of God; acts of war or te rrorism; and orders by a government official, government agency, other regulatory authority, or a regional transmission organization, acting under and authorized by applicable law, that directs Defendants to operate an AEP Eastern System Unit in response to a local or system-wide (state-wide or regional) emergency (which could include unanticipated required operation to avoid loss of load or unserved load). Depending upon the circumstances and Defendants’ response to such circumstances, failure of a permitting authority to issue a necessary permit in a timely fashion may constitute a Force Majeure Event where the failure of the permitting authority to act is beyond the control of Defendants and Defendants have taken all steps available to it to obtain the necessary permit, including, but not limited to: submitting a complete permit application; responding to requests for additional information by the permitting authority in a timely fashion; and accepting lawful permit terms and conditions after expeditiously exhausting any legal rights to appeal terms and conditions imposed by the permitting authority. 63166. As part of the resolution of any matter submitted to this Court under Section XV (Dispute Resolution) of this Consent Decree regarding a claim of Force Majeure, the Plaintiffs and Defendants by agreement, or this Court by order, may in appropriate circumstances extend or modify the schedule for completion of work under this Consent Decree to account for the delay in the work that occurred as a result of any delay agreed to by the Plaintiffs or approved by the Court. Defendants shall be liable for stipulated penalties for their failure thereafter to complete the work in accordance with the extended or modified schedule (provided that Defendants shall not be precluded from making a fu rther claim of Force Majeure with regard to meeting any such extended or modified schedule).
XV. DISPUTE RESOLUTION 167. The dispute resolution procedure provided by this Section shall be available to resolve all disputes arising under this Consent Decree, provided that the Party invoking such procedure has first made a good faith attempt to resolve the matter with the other Parties.
168. The dispute resolution procedure required herein shall be invoked by one Party giving written notice to the other Parties advising of a dispute pursuant to this Section. The notice shall describe the nature of the dispute and shall state the noticing Party’s position with regard to such dispute. The Parties receiving such a notice shall acknowledge receipt of the notice, and the Parties in dispute shall expeditiously schedule a meeting to discuss the dispute informally not later than fourteen (14) days following receipt of such notice. 169. Disputes submitted to dispute resolution under this Section shall, in the first instance, be the subject of informal negotiations among the disputing Parties. Such period of informal negotiations shall not extend beyond thirty (30) days from the date of the first meeting among the disputing Parties’ representatives unless they agree in writing to shorten or extend 64this period. During the informal negotiations period, the disputing Parties may also submit their dispute to a mutually agreed upon alternative dispute resolution (ADR) forum if the Parties agree that the ADR activities can be completed within the 30-day informal negotiations period (or such longer period as the Parties may agree to in writing).
170. If the disputing Parties are unable to reach agreement during the informal negotiation period, the Plaintiffs shall provide Defendants with a written summary of their position regarding the dispute. The written position provided by Plaintiffs shall be considered binding unless, within forty-five (45) days thereafter, Defendants seek judicial resolution of the dispute by filing a petition with this Court. The Plaintiffs may respond to the petition within forty-five (45) days of filing. In their initia l filings with the Court under this Paragraph, the disputing Parties shall state their respective positions as to the applicable standard of law for resolving the particular dispute.
171. The time periods set out in this Section may be shortened or lengthened upon motion to the Court of one of the Parties to the dispute, explaining the Party’s basis for seeking such a scheduling modification.
172. This Court shall not draw any inferences nor establish any presumptions adverse to any disputing Party as a result of invocation of this Section or the disputing Parties’ inability to reach agreement.
173. As part of the resolution of any dispute under this Section, in appropriate circumstances the disputing Parties may agree, or this Court may order, an extension or modification of the schedule for the completion of the activities required under this Consent Decree to account for the delay that occurred as a result of dispute resolution. Defendants shall be liable for stipulated penalties for their failure thereafter to complete the work in accordance 65with the extended or modified schedule, provided that Defendants shall not be precluded from asserting that a Force Majeure Event has caused or may cause a delay in complying with the extended or modified schedule.
174. The Court shall decide all disputes pursuant to applicable principles of law for resolving such disputes. In their initial filings with the Court under Paragraph 170, the disputing Parties shall state their respective positions as to the applicable standard of law for resolving the particular dispute.
XVI. PERMITS 175. Unless expressly stated otherwise in this Consent Decree, in any instance where otherwise applicable law or this Consent Decree requires Defendants to secure a permit to authorize construction or operation of any device contemplated herein, including all preconstruction, construction, and operating permits required under state law, Defendants shall make such application in a timely manner. Defendants shall provide Notice to Plaintiffs under Section XVIII (Notices), for each Unit that Defendants submit an application for any permit described in this Paragraph 175.
176. Notwithstanding the previous Paragraph, nothing in this Consent Decree shall be construed to require Defendants to apply for or obtain a PSD or Nonattainment NSR permit for physical changes in, or changes in the method of operation of, any AEP Eastern System Unit that would give rise to claims resolved by Para graph 132 and 133, subject to Paragraphs 134 through 138, or Paragraphs 139 and 141 of this Consent Decree.
177. When permits are required as described in Paragraph 175, Defendants shall complete and submit applications for such permits to the appropriate authorities to allow time for all legally required processing and review of the permit request, including requests for additional 66information by the permitting authorities. Any failure by Defendants to submit a timely permit application for any Unit in the AEP Eastern System shall bar any use by Defendants of Section XIV (Force Majeure) of this Consent Decree, where a Force Majeure claim is based on permitting delays.
178. Notwithstanding the reference to Title V permits in this Consent Decree, the enforcement of such permits shall be in accordance with their own terms and the Act. The Title V permits shall not be enforceable under this Consent Decree, although any term or limit established by or under this Consent Decree shall be enforceable under this Consent Decree regardless of whether such term or limit has or will become part of a Title V permit, subject to the terms of Section XXVI (Conditional Termina tion of Enforcement Under Decree) of this
Consent Decree. 179. Within three (3) years from the Date of Entry of this Consent Decree, and in accordance with federal and/or state requirements for modifying or renewing a Title V permit, Defendants shall amend any applicable Title V permit application, or apply for amendments to their Title V permits, to include a schedule for any Unit-specific performance, operational, maintenance, and control technology requirements established by this Consent Decree including, but not limited to, required emission rates or other limitations. For Units subject to a requirement to Retire, Retrofit, or Re-power, Defendants shall apply to modify, renew, or obtain any applicable Title V permit to include a schedule for any Unit-specific performance, operation, maintenance, and control technology requirements established by this Consent Decree including, but not limited to, required emission rates or other limitations, within (12) twelve months of making such election to Retire, Retrofit, or Re-power.

67180. Within one (1) year from commencement of operation of each pollution control device to be installed, upgraded, and/or operated under this Consent Decree, Defendants shall apply to include the requirements and limitations enumerated in this Consent Decree into federally-enforceable non-Title V permits and/or site-specific amendments to the applicable state implementation plans to reflect all new requirements applicable to each Unit in the AEP Eastern System, the Plant-Wide Annual Rolling Average Tonnage Limitation for SO 2 at Clinch River, and the Plant-Wide Annual Tonnage Limitation for SO 2 at Kammer. 181. Defendants shall provide the United States with a copy of each application for a federally-enforceable non-Title V permit or amendment to a state implementation plan, as well as a copy of any permit proposed as a result of such application, to allow for timely participation in any public comment period.
182. Prior to termination of this Consent Decree, Defendants shall obtain enforceableprovisions in their Title V permits for the AEP Eastern System that incorporate (a) any Unitspecific requirements and limitations of this Cons ent Decree, such as performance, operational, maintenance, and control technology requirements, (b) the Plant-Wide Annual Rolling Average Tonnage Limitation for SO 2 at Clinch River and the Plant-Wide Annual Tonnage Limitation for
SO 2 at Kammer, and (c) the Eastern System-Wide Annual Tonnage Limitations for SO 2 and
NO x . If Defendants do not obtain enforceable pr ovisions for the Eastern System-Wide Annual Tonnage Limitations for SO 2 and NO x in such Title V permits, then the requirements in Paragraphs 86 and 67 shall remain enforceable under this Consent Decree and shall not be subject to termination.
183. If Defendants sell or transfer to an entity unrelated to Defendants (“Third-Party Purchaser”) part or all of Defendants’ Ownership Interest in a Unit in the AEP Eastern System, 68Defendants shall comply with the requirements of Section XIX (Sales or Transfers of Operational or Ownership Interests) with regard to that Unit prior to any such sale or transfer unless, following any such sale or transfer, Defendants remain the holder of the Title V permit for such facility.
XVII. INFORMATION COLLECTION AND RETENTION 184. Any authorized representative of the United States, including attorneys, contractors, and consultants, upon presentation of credentials, shall have a right of entry upon the premises of any facility in the AEP Eastern System at any reasonable time for the purpose of:

a. monitoring the progress of activities required under this Consent Decree; b. verifying any data or information submitted to the United States in accordance with the terms of this Consent Decree;

c. obtaining samples and, upon request, splits of any samples taken by Defendants or their representatives, contractors, or consultants; and d. assessing Defendants’ compliance with this Consent Decree. 185. Defendants shall retain, and instruct their contractors and agents to preserve, all non-identical copies of all records and documents (including records and documents in electronic form) now in their or their contractors’ or ag ents’ possession or control (with the exception of their contractors’ copies of field drawings a nd specifications), and that directly relate to Defendants’ performance of their obligations under this Consent Decree until six (6) years following completion of performance of such obligations. This record retention requirement shall apply regardless of any corporate document retention policy to the contrary.
186. All information and documents submitted by Defendants pursuant to this Consent Decree shall be subject to any requests under applicable law providing public disclosure of 69documents unless (a) the information and documents are subject to legal privileges or protection or (b) Defendants claim and substantiate in accordance with 40 C.F.R. Part 2 that the information and documents contain confidential business information.
187. Nothing in this Consent Decree shall limit the authority of EPA to conduct tests and inspections at Defendants’ facilities under Section 114 of the Act, 42 U.S.C. § 7414, or any other applicable federal or state laws, regulations, or permits.

Any Party may change either the notice recipient or the address for providing notices to it by serving all other Parties with a notice setting forth such new notice recipient or address.
XIX. SALES OR TRANSFERS OF OPERATIONAL OR OWNERSHIP INTERESTS 191. If Defendants propose to sell or transfer an Operational or Ownership Interest to an entity unrelated to Defendants (“Third Party”), they shall advise the Third Party in writing of the existence of this Consent Decree prior to such sale or transfer, and shall send a copy of such written notification to the Plaintiffs pursuant to Section XVIII (Notices) of this Consent Decree at least sixty (60) days before such proposed sale or transfer. 192.

If the Plaintiffs agree, the Plaintiffs, Defendants, and the Third Party that has become a party to this Consent Decree pursuant to Paragraph 192, may execute a modification that relieves Defendants of liability under this Consent Decree for, and makes the Third Party liable for, all obligations and liabilities applicable to the purchased or transferred Interests. Notwithstanding the foregoing, however, Defendant s may not assign, and may not be released from, any obligation under this Consent Decree that is not specific to the purchased or transferred Interests, including the obligations set forth in Section VIII (Environmental Mitigation Projects), Paragraphs 86 and 67, and Section IX (Civil Penalty). Defendants may propose and the Plaintiffs may agree to restrict the scope of the joint and several liability of any purchaser or transferee for any obligations of th is Consent Decree that are not specific to the transferred or purchased Interests, to the extent such obligations may be adequately separated in an enforceable manner. 195.

Paragraphs 191-195 of this Consent Decree do not apply if an Interest is sold or transferred solely as collateral security in order to consummate a financing arrangement (not including a sale-leaseback), so long as Defendants: (a) remain the operator (as that term is used and interpreted under the Clean Air Act) of the subject AEP Eastern System Unit(s); (b) remain

75subject to and liable for all obligations and liabilities of this Consent Decree; and (c) supply Plaintiffs with the following certification within thirty (30) days of the sale or transfer:

“ Certification of Change in Ownership Interest Solely for Purpose of Consummating Financing . We, the Chief Executive Officer and General Counsel of American Electric Power (“AEP”), hereby jointly certify under Title 18 U.S.C. Section 1001, on our own behalf and on behalf of AEP, that any change in AEP’s Ownership Interest in any AEP Eastern System Unit that is caused by the sale or transfer as collateral security of such Ownership Interest in such Unit(s) pursuant to the financing agreement consummated on [insert applicable date] between AEP and [insert applicable entity]: a) is made solely for the purpose of providing collateral security in order to consummate a financing arrangement; b) does not impair AEP’s ability, legally or otherwise, to comply timely with all terms and provisions of the Consent Decree entered in United States, et al. v. American Electric Power Service Corp., et al., Civil Action No. C2-99-1250 (“AEP I”) and United States, et al. v. American Electric Power Service Corp., et al. , Civil Action Nos.

Consent Decree.

76XXII. MODIFICATION 199. The terms of this Consent Decree may be modified only by a subsequent written agreement signed by the Plaintiffs and Defendants. Where the modification constitutes a material change to any term of this Decree, it shall be effective only upon approval by the Court.
XXIII. GENERAL PROVISIONS 200. This Consent Decree is not a permit. Compliance with the terms of this Consent Decree does not guarantee compliance with all applicable federal, state, or local laws or regulations. The limitations and requirements set forth herein do not relieve Defendants from any obligation to comply with other state and federal requirements under the Clean Air Act at any Units covered by this Consent Decree, including the Defendants’ obligation to satisfy any state modeling requirements set forth in a state implementation plan.
201. This Consent Decree does not apply to any claim(s) of alleged criminal liability.
202. In any subsequent administrative or judicial action initiated by any of the Plaintiffs for injunctive relief or civil penalties relating to the facilities covered by this Consent Decree, Defendants shall not assert any defense or claim based upon principles of waiver,

res judicata , collateral estoppel, issue preclusion, claim preclusion, or claim splitting, or any other defense based upon the contention that the claims raised by any of the Plaintiffs in the subsequent proceeding were brought, or should ha ve been brought, in the instant case; provided, however, that nothing in this Paragraph affects the validity of Paragraphs Paragraph 132 and 133, subject to Paragraphs 134 through 138, or Paragraphs 139 and 141.
203. Except as specifically provided by this Consent Decree, nothing in this Consent Decree shall relieve Defendants of their obligation to comply with all applicable federal, state, and local laws and regulations. Subject to th e provisions in Section X (Resolution of Civil 77Claims Against Defendants), nothing contained in this Consent Decree shall be construed to prevent or limit the rights of the Plaintiffs to obtain penalties or injunctive relief under the Act or other federal, state, or local statutes, regulations, or permits.
204. At any time prior to termination of this Consent Decree, Defendants may request approval from Plaintiffs to implement other control technology for SO 2 or NO x than what is required by this Consent Decree. In seeking such approval, Defendants must demonstrate that such alternative control technology is capable of achieving pollution reductions equivalent to an FGD (for SO 2 ) or SCR (for NO x ) at the Units in the AEP Eastern System at which Defendants seek approval to implement such other control technology for SO 2 or NO x . Approval of such a request is solely at the discretion of the Plaintiffs. 205. Nothing in this Consent Decree is intended to, or shall, alter or waive any applicable law (including but not limited to any defenses, entitlements, challenges, or clarifications related to the Credible Evidence Rule, 62 Fed. Reg. 8314 (Feb. 24, 1997)) concerning the use of data for any purpose under the Act generated either by the reference methods specified herein or otherwise.
206. Each limit and/or other requirement established by or under this Consent Decree is a separate, independent requirement.
207. Performance standards, emissions limits, and other quantitative standards set by or under this Consent Decree must be met to the number of significant digits in which the standard or limit is expressed. For example, an Emission Rate of 0.100 is not met if the actual Emission Rate is 0.101. Defendants shall round the fourth significant digit to the nearest third significant digit, or the third significant digit to the nearest second significant digit, depending upon whether the limit is expressed to three or two significant digits. For example, if an actual 78Emission Rate is 0.1004, that shall be reported as 0.100, and shall be in compliance with an Emission Rate of 0.100, and if an actual Emission Rate is 0.1005, that shall be reported as 0.101, and shall not be in compliance with an Emission Rate of 0.100. Defendants shall report data to the number of significant digits in which the standard or limit is expressed.
208. This Consent Decree does not limit, enlarge, or affect the rights of any Party to this Consent Decree as against any third parties. 209. This Consent Decree constitutes the final, complete, and exclusive agreement and understanding among the Parties with respect to the settlement embodied in this Consent Decree, and supersedes all prior agreements and understandings among the Parties related to the subject matter herein. No document, representation, inducement, agreement, understanding, or promise constitutes any part of this Consent Decree or the settlement it represents, nor shall they be used in construing the terms of this Consent Decree.
210. Except for Citizen Plaintiffs, each Party to this action shall bear its own costs and attorneys’ fees. Defendants shall reimburse the Citizen Plaintiffs’ attorneys’ fees and costs, pursuant to 42 U.S.C. § 7604(d), and the agreement between counsel for Defendants and Citizen Plaintiffs within thirty (30) days of th e Date of Entry of this Consent Decree.
XXIV. SIGNATORIES AND SERVICE

XXV. PUBLIC COMMENT
214. The Parties agree and acknowledge that final approval by the United States and the entry of this Consent Decree is subject to the procedures of 28 C.F.R. § 50.7, which provides for notice of lodging of this Consent Decree in the Federal Register, an opportunity for public comment, and the right of the United States to withdraw or withhold consent if the comments disclose facts or considerations which indicate that the Consent Decree is inappropriate, improper, or inadequate. The Defendants shall not oppose entry of this Consent Decree by this Court or challenge any provision of this Consen t Decree unless the United States has notified the Defendants, in writing, that the United States no longer supports entry of the Consent Decree.
XXVI. CONDITIONAL TERMINATION OF ENFORCEMENT UNDER DECREE

The key criteria for selection of components of the Mobile Source Projects are the magnitude of the expected environmental benefit(s) in relation to the cost.
B. Diesel Tug/Train Project
1. Defendants are among the leading barge operators in the country, with operations on the Ohio River, the Mississippi River, and the Gulf Coast. Barges are propelled by tugboats, which generally use a type of marine diesel fuel known as No. 2 distillate fuel oil. Tugboats that switch to ultra-low sulfur diesel fuel (“ULSD”) reduce emissions of NO X , PM, volatile organic compounds (“VOCs”), and other air pollutants. All marine diesel fuel must be ULSD by June 1, 2012, pursuant to EPA’s Nonroad Diesel Rule ( see “Control of Emissions of Air Pollution from Nonroad Diesel Engines and Fuels; Final Rule,” 69 Fed. Reg. 38,958 (June 29, 2004)). Defendants also receive coal by diesel trains.
2. As part of the plan for Mobile Source Projects, Defendants may elect to achieve accelerated emission reductions from their tugboat fleet on the Ohio River (“Ohio River Tug Fleet”) and/or their diesel powered trains used at or near their power plants, as one of the three possible mobile source Projects under this Consent Decree (“Diesel Tug/Train Project”).
3. The Diesel Tug/Train Project shall require one or more of the following:

a. The accelerated retrofitting or re-powering of Tugs with engines that require the use of ULSD. Selection of this Project is expressly conditioned upon identification of satisfactory technology and an agreement between EPA and Defendants on how to credit Project Dollars towards this project. b. The retrofitting or repowering of the marine engines in the Ohio River Tug Fleet with diesel oxidation catalysts (“DOCs”), diesel particulate filters (“DPFs”), or other equivalent advanced technologies that reduce emissions of PM and VOCs from marine engines in tugboats (collectively “DOC/DPFs”). Defendants shall only install DOCs/DPFs that have received applicable approvals or 5verifications, if any, from the relevant regulatory agencies for reducing emissions from tugboat engines. Defendants must maintain any DOCs/DPFs installed as part of the Tug Project for the useful life of the equipment (as defined in the proposed Plan), even after the completion of the Tug Project. Project Dollars may be spent on DOCs/DPFs within 5 years of the Date of Entry, in accordance with the approved schedule for the mitigation projects in this Appendix.

c. The accelerated use of ULSD for the Ohio River Tug Fleet, from the Date of Entry through January 1, 2012. Notwithstanding any other provision of this Consent Decree, including this Appendix, Defendants shall only receive credit for the incremental cost of ULSD as compared to the cost of the fuel Defendants would otherwise utilize. d. Emission reduction measures for diesel powered trains. Such measures may include retro-fitting with, or conversion to, Multiple Diesel Engine GenSets that are EPA Tier III Off-Road certified; Diesel Electric Hybrid; Anti-idling controls/strategies and Auto Shut-Off capabilities. Selection of this Project is expressly conditioned upon identification of satisfactory technology and an agreement between EPA and Defendants on how to credit Project Dollars towards this project.
4. The proposed plan for the Diesel Tug/Train Project shall:

These motor vehicles are generally powered by conventional diesel or gasoline engines and include vehicles such as diesel “bucket” trucks. The use of hybrid engine technologies in Defendants’ motor vehicles, such as diesel-electric engines, will improve fuel efficiency and reduce emissions of NO X , PM, VOCs, and other air pollutants.
2. As part of the plan for Mobile Source Projects, Defendants may elect to spend Project Dollars on the replacement of conventional motor vehicles in their fleet with newly manufactured Hybrid Vehicles (“Hybrid Vehicle Fleet Project”).
3. The proposed plan for the Hybrid Vehicle Fleet Project shall:

a. Propose the replacement of conventional gasoline or diesel powered motor vehicles (such as bucket trucks) with Hybrid Vehicles. For purposes of this subsection of this Appendix, “Hybrid Vehicle” means a vehicle that can generate and utilize electric power to reduce the vehicle’s consumption of fossil fuel. Any Hybrid Vehicle proposed for inclusion in the Hybrid Fleet Project shall meet all applicable engine standards, certifications, and/or verifications. b. Provide for Hybrid Vehicles replacement in that portion of Defendants’ fleet in Indiana, Ohio, Michigan, West Virginia, Virginia, and/or Kentucky. Notwithstanding any other provision of this Consent Decree, including this Appendix, Defendants shall only receive credit toward Project Dollars for the incremental cost of Hybrid Vehicles as compared to the cost of a newly manufactured, similar motor vehicle.

c. Prioritize the replacement of diesel-powered vehicles in Defendants’ fleet. d. Provide a method to account for the costs of the Hybrid Vehicles, including the incremental costs of such vehicles as compared to conventional gasoline or diesel motor vehicles.

D. Truck Stop Electrification
1. Long-haul truck drivers typically idle their engines at night at rest areas to supply heat or cooling in their sleeper cab compartments, and to maintain vehicle battery charge while electrical appliances such as televisions, computers, and microwaves are in use. Modifications to rest areas to provide parking spaces with electrical power, heat, and air conditioning will allow truck drivers to turn their engines off. Truck stop electrification reduces idling time and therefore reduces diesel fuel usage, and thus reduces emissions of PM, NO x , and VOCs.
2. As part of the plan for Mobile Source Projects, Defendants may elect to achieve emission reductions by truck stop electrification, which shall include, where necessary, techniques and infrastructure needed to support such a program (“Truck Stop Electrification Project”).
3. The proposed plan for the Truck Stop Electrification Project shall:

a. Identify truck stops in one or more of the following States for Electrification: Ohio, Indiana, Kentucky, North Carolina, Pennsylvania, West Virginia, and Virginia. EPA may give preference to electrification Projects that are co-located, if possible, along the same transportation corridor. b. Describe the level of expected usage of the planned electrification facilities, air quality in the vicinity of the proposed Projects, proximity of the proposed Project to population centers, and whether the owner or some other entity is willing to pay for some portion of the work.

c. Provide for the construction of truck stop electrification stations with established technologies and equipment. d. Account for hardware procurement and installation costs at the recipient truck stops.

e. Include a schedule for completing each portion of the Project.

Due to space constraints and potential interferences, monitors are currently located in the inlet duct for one FGD module on each Unit and at the combined outlet from both FGD modules for each Unit prior to entering the stack using best engineering judgment. 3. On or before December 31, 2008, Defendants shall submit a monitoring plan to EPA for approval that will propose wher e to site and install an additional inlet monitor in each of the unmonitored FGD inlet ducts for each Unit, and include a requirement that Defendant s submit a complete certification application for the Conesville Units 5 & 6 monitoring system to EPA and the state permitting authority. 4. The Monitoring Plan will incorporate th e applicable procedures and quality assurance testing found in 40 C.F.R. Part 75, subject to the following:

a. The PS-2 siting criteria will not be applied to these monitoring systems; however, the majority of the procedures in Section 8.1.3.2 of PS-2 will be followed. Sampling of at least nine (9) sampling points selected in accordance with PS-1 will be performed pr ior to the initial RATA. If the resultant SO 2 emission rates for any single sampling point calculated in accordance with Equation 19.7 are all wi thin 10% or 0.02 lb/mmBtu of the mean of all nine (9) sampling points, the alternative traverse point locations (0.4, 1.2, and 2.0 meters from the duct wall) will be representative and may be used for all subsequent RATAs. b. The required relative accur acy test audit will be performed in accordance with the procedures of 40 C.F.R. Pa rt 75, except that th e calculations will be performed on an SO 2 emission rate basis ( i.e. , lb/mmBtu).

c. The criteria for passing the relative a ccuracy test audit will be the same criteria that 40 C.F.R. Part 75 require s for relative accuracy or alternative performance specification as provided for NO x emission rates.

1d. “Diluent capping” ( i.e. , 5% CO 2 ) will be applied to the SO 2 emission rate for any hours where the measured CO 2 concentration rounds to zero.

e. Results of quality assura nce testing, data gathered by the inlet and outlet monitoring systems, and the resultant 30-day Rolling Average Removal Efficiencies for these monitoring syst ems are not required to be reported in the quarterly reports submitted to EPA’s Clean Air Markets Division for purposes of 40 C.F.R. Part 75. Results will be maintained at the facility and available for inspec tion, and the 30-day Rolling Average Removal Efficiency will be reported in accordance with the requirements of the Consent Decree and Appendix B. Equivalent data retention and reporting requirements will be incorporat ed into the applicable permits for these Units. f. Missing Data Substitution of 40 C.F.R Part 75 will not be implemented.
g. Initial performance testing will be performed before the effective date of the 30-Day Rolling Average Removal E fficiency requirements, and the results will be reported to Plaintiffs as part of the annual report submitted in accordance with Appendix B. II. Calculation of 30-Day Rolling Average Removal Efficiency 1. Removal efficiency shall be calculated by the equation: [SO 2 emission rate Inlet – SO 2 emission rate Outlet ] / SO 2 emission rate Inlet * 100 2. Inlet and outlet emission rates shal l be calculated using the methodology specified in 40 C.F.R. Part 60 A ppendix B – Method 19. Inlet emission rates will be based on the average of the valid reco rded values calculated for each of the inlet FGD monitors at each Unit. Measurements are made on a wet basis, so Equation 19.7 will be utilized to determine the hourly SO 2 emission rate at each location. To make the conversion between the measured wet SO 2 and CO 2 concentrations and an emission rate in pounds per million BTU, an electronic Data System will perform Equation 19.7 using the SO 2 ppm conversion factor from Table 19-1 of Method 19 and the Fc factor for the applicable fuel (currently bituminous coal) in Table 19-2 of Method 19. The resulting equation will be: Emission rate (lb SO 2 /mmBtu) = 1.660 x 10 -7 * SO 2 (in ppm) * Fc * 100 / CO 2 (in %) 3. The electronic data system w ill calculate the hourly average SO 2 and CO 2 concentration in accordance with 40 C.F.R. Part 75 quality control/quality assurance requirements and will compute and retain these SO 2 emission rates for every operating hour mee ting the minimum data capture requirements in accordance with 40 C.F.R. Part 75. Prior to the

2calculation of the SO 2 emission rate, hourly SO 2 and CO 2 concentrations will be rounded to the nearest tenth ( i.e. , 0.1 ppm or 0.1 % CO 2 ) and the resulting SO 2 emission rate will be rounded to the nearest thousandth ( i.e. , 0.001 lb/mmBtu). 4. From these hourly SO 2 emission rates, SO 2 removal efficiencies will be calculated for each hour when the Unit is firing fossil fuel, and the hourly SO 2 and CO 2 monitors meet the QA/QC requi rements of Part 75. Hourly SO 2 removal efficiencies will be computed by taking the hourly inlet SO 2 emission rate minus the outlet SO 2 emission rate, dividing the result by inlet SO 2 emission rate and multiplying by 100. The resulting removal efficiency will be rounded to the nearest tenth ( i.e. , 95.1%). Daily SO 2 removal efficiencies will be calcula ted by taking the sum of Hourly SO 2 removal efficiencies and dividing by the number of valid monitored hours for each Operating Day. The resulti ng daily removal efficiencies will be rounded to the nearest tenth ( i.e. , 95.1%). 5. The 30-Day Rolling Average Removal Efficiency will be computed by taking the current Operating Day’s daily SO 2 removal efficiency (as described in Paragraph 4 of this Appendix C) plus the previous 29 Operating Days’ daily SO 2 removal efficiency, and dividing the sum by 30. In the event that a daily SO 2 removal efficiency is not available for an Operating Day, Defendants shall excl ude that Operating Day from the calculation of the 30-Day Rolling Av erage Removal Efficiency. The resulting 30-day Rolling Average Rem oval Efficiency will be rounded to the nearest tenth of a percent ( i.e. , a value of 95.04% rounds down to 95.0%, and a value of 95.05% rounds up to 95.1%).
