The inability of Defendant to obtain a permit in adequate time to allow compliance with the deadlines stated in this Consent Decree may be considered a Force Majeure event if Defendant demonstrates that it exercised best efforts to timely fulfill its permitting obligations and has otherwise satisfied the requirements of Section XIV (Force Majeure) of this Consent Decree. If, after demonstrating compliance with the requirements of this Paragraph, Defendant determines that it is unable to timely obtain a permit or approval necessary to install and Continuously Operate Control Technology under this Consent Decree, then Defendant shall within 10 days notify EPA in writing pursuant to Section XIV (Force Majeure) of this Consent Decree and shall request an extension of time necessary to obtain such permit or approval and install and shake down the required improvements. If EPA determines that Defendant's inability to timely obtain any such required permit or approval is a Force Majeure event, then the provisions of Paragraph 67 shall apply to extend the deadline for installation and commencement of Continuous Operation of the Control Technology and for achieving and maintaining compliance with the applicable 30-Day Rolling Average Emission Limits. 41. In addition to having first obtained any required preconstruction permits or other approvals pursuant to Paragraph 40, within 3 months after the establishment of the final 30-Day Rolling Average Emission Limit for NOx established pursuant to Section V (NOx Control Technology, Emissions Limits and Monitoring Requirements), including Final Dispute Resolution if applicable, Defendant shall apply to NDEP to include the applicable requirements of Sections V.A (NOx Control Technology and Emission Limits) and VI.A (SO2 Emission Limits), and any monitoring requirements, including those in Sections V.B (NOx Continuous Emission Monitoring System) and VI.B (SO2 Continuous Emission Monitoring Systems) of this Consent Decree in a federally enforceable operating permit or other permit or approval issued under the SIP of Nevada and under authority independent of the NDEP's authority to issue Title V permits. For the purpose of this Paragraph, the ammonia monitoring requirements identified in Section V do not constitute NOx monitoring requirements. Following submission of the application for the permit or approval, Defendant shall cooperate with NDEP by promptly submitting all information that such permitting authority seeks following its receipt of the application for the permit. The methods specified in this Consent Decree for demonstrating compliance with the limits in this Consent Decree are not intended to change the means by which Defendant demonstrates compliance with standards not addressed by this Consent Decree. The requirements of this Paragraph are satisfied if a preconstruction permit was obtained, that permit serves as a state operating permit under the Nevada SIP and that permit contains the elements identified in this Paragraph. 42. Upon issuance of any permit or approval required under Paragraphs 40 and 41, Defendant shall file any applications necessary to incorporate the requirements of that permit into the Title V operating permit of the Facility. Defendant shall not challenge the inclusion in any such permit of the Emission Limits expressly prescribed in this Consent Decree (including, where applicable, 30-Day Rolling Average Emission Limits for NOx determined in accordance with Appendix A) or of any other requirement of this Consent Decree. 43. For each Kiln, Defendant shall provide U.S. EPA with a copy of each application for a permit to address or comply with any provision of this Consent Decree, as well as a copy of any permit proposed as a result of such application, to allow for timely U.S. EPA participation in any public comment opportunity. 44. In lieu of incorporating the terms of the Consent Decree directly into a permit issued under a SIP pursuant to Paragraph 41, Defendant may request that NDEP submit the portions of the Consent Decree applicable to the Facility in Nevada to the U.S. EPA for approval under the State's SIP in accordance with 42 U.S.C. § 7410(k). Upon approval by the U.S. EPA, those portions of this Consent Decree will be incorporated into the Nevada SIP, and subsequently incorporated into Title V permits for the Facility consistent with applicable requirements in 40 C.F.R. Part 70 or Nevada-specific rules adopted and approved consistent with Part 70. Defendant agrees not to contest the submittal of any such proposed SIP revision that incorporates the terms of this Consent Decree to U.S. EPA, or U.S. EPA's approval of such submittal, or the incorporation of the applicable portions of this Consent Decree through these SIP requirements into the Title V permits. SECTION XI: REVIEW AND APPROVAL OF SUBMITTALS 45. After review of any plan, report, or other document that is required to be submitted pursuant to this Consent Decree, U.S. EPA, shall in writing: (a) approve the submission; (b) approve the submission upon specified conditions; (c) approve part of the submission and disapprove the remainder; or (d) disapprove the submission. 46. If the submission is approved pursuant to Paragraph 45, Defendant shall take all actions required by the plan, report, or other document, in accordance with the schedules and requirements of the plan, report, or other document, as approved. If the submission is conditionally approved or approved only in part, pursuant to Paragraph 45.b or c, Defendant shall, upon written direction of U.S. EPA, take all actions required by the approved plan, report, or other item that U.S. EPA determines are technically severable from any disapproved portions, subject to Defendant's right to dispute the specified conditions or the disapproved portions, under Section XV (Dispute Resolution) of this Consent Decree and the severability of such portions. 47. If the submission is disapproved in whole or in part pursuant to Paragraph 45.c or d, Defendant shall, within 45 Days or such other time as the Parties agree to in writing, correct all deficiencies and resubmit the plan, report, or other item, or disapproved portion thereof, for approval, in accordance with the preceding Paragraphs. If the resubmission is approved in whole or in part, Defendant shall proceed in accordance with the preceding Paragraph. 48. Any stipulated penalties applicable to an original submission that is disapproved in whole or in part pursuant to Paragraph 45.c or d, as provided in Section XIII (Stipulated Penalties) of this decree, shall continue to accrue during the period specified in Paragraph 47, but any stipulated penalties that accrue following the receipt of the submission shall not be payable unless the resubmission is untimely or is disapproved in whole or in part; provided that, if the original submission was so deficient as to constitute a material breach of Defendant's obligations under this Decree, the stipulated penalties applicable to the original submission shall be due and payable notwithstanding any subsequent resubmission. 49. If a resubmitted plan, report, or other item, or portion thereof, is disapproved in whole or in part, U.S. EPA may again require Defendant to correct any deficiencies in accordance with the preceding Paragraphs, or may itself correct any deficiencies and seek stipulated penalties, subject to Defendant's right to invoke Dispute Resolution under Section XV (Dispute Resolution) of this Consent Decree. SECTION XII: REPORTING REQUIREMENTS 50. Within 30 Days after the end of each half calendar year (i.e., June 30, December 31) after the Effective Date, until termination of this Consent Decree pursuant to Section XXIII (Termination), Defendant shall submit a semi-annual report to U.S. EPA for the immediately preceding half calendar year period that shall: a. Identify any and all dates on which Defendant has installed, or describe the progress of installation of, each Control Technology required for each Kiln under Section V (NOx Control Technology, Emission Limits and Monitoring Requirements) and describe any problems encountered or anticipated during such installation, together with implemented or proposed solutions; b. Identify any and all dates on which Defendant has completed installation of, or describe the progress of installation of, each continuous monitoring system required under Section V.B (NOx and Ammonia Continuous Emission Monitoring Systems) and Section VI.B (SO2 Continuous Emission Monitoring Systems) and describe any problems encountered or anticipated during such installation, together with implemented or proposed solutions; c. Provide, in electronic format able to be manipulated with Microsoft Excel, all CEMS data collected for each Kiln, reduced to 1 hour averages, in accordance with 40 C.F.R. § 60.13(h)(2), including an explanation of any periods of CEMS downtime together with any missing data for which Defendant applied missing data substitution procedures, under Section V.B (NOx and Ammonia Continuous Emission Monitoring Systems) or Section VI.B (SO2 Continuous Emission Monitoring Systems); d. Demonstrate compliance with all applicable 30-Day Rolling Average Emission Limits of this Consent Decree; e. Provide a complete description and status of all actions Defendant has undertaken to comply with each of the Appendices of this Consent Decree; f. Describe the status of permit applications and any proposed SIP revisions made to implement the requirements of this Consent Decree; and g. Describe the status of any operation and maintenance work relating to activities required under this Consent Decree.

The semi-annual report shall also include a description of any non-compliance with the requirements of this Consent Decree and an explanation of the likely cause of non-compliance and of the remedial steps taken, or to be taken, to prevent or minimize such non-compliance.

51. If Defendant violates, or has reason to believe that it may violate, any requirement of this Consent Decree, Defendant shall notify the United States of such violation and its likely duration, in writing (including by email), within ten (10) Business Days of the Day Defendant first becomes aware of the violation, with an explanation of the violation's likely cause and of the remedial steps taken, or to be taken, to prevent or minimize such violation and to mitigate any adverse effects of such violation. Defendant shall investigate the cause of the violation and shall then submit an amendment to the report required under Paragraph 50, including a full explanation of the cause of the violation, within 30 Days of the Day Defendant becomes aware of the cause of the violation. Nothing in this Paragraph or the following Paragraph relieves Defendant of its obligation to provide the notice required by Section XIV (Force Majeure) of this Consent Decree or to avail itself of Section XIV (Force Majeure) if Defendant contends a Force Majeure event occurred. 52. Whenever any violation of this Consent Decree, or of any applicable permits required under this Consent Decree, or any other event affecting Defendant's performance under this Consent Decree, or the performance of the Kilns, may pose an immediate threat to the public health or welfare or the environment, Defendant shall notify U.S. EPA, orally or by electronic or facsimile transmission as soon as possible, but no later than 24 hours after Defendant first knew, or should have known, of the violation or event. This procedure is in addition to the requirements set forth in the preceding Paragraph. 53. All reports shall be submitted to the persons designated in Section XIX (Notices) of this Consent Decree. 54. Each report submitted by Defendant under this Section or Appendix A or Appendix B shall be signed by an official of the submitting party and include the following certification: I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.

This certification requirement does not apply to emergency or similar notifications where compliance would be impractical. Failure to certify as immediately above is a violation of the Consent Decree and is subject to stipulated penalties.

55. The reporting requirements of this Consent Decree do not relieve Defendant of any reporting obligations required by the Clean Air Act or implementing regulations, or by any other federal, State, or local law, regulation, permit, or other requirement. 56. Any information provided pursuant to this Consent Decree may be used by the United States in any proceeding to enforce the provisions of this Consent Decree and as otherwise permitted by law. SECTION XIII: STIPULATED PENALTIES 57. Defendant shall be liable for stipulated penalties to the United States for violations of this Consent Decree as specified in Table 2 below, unless excused under Section XIV (Force Majeure). A violation includes failing to perform any obligation required by the terms of this Decree, including any work plan or schedule approved under this Decree, according to all applicable requirements of this Decree and within the specified time schedules established by or approved under this Decree. Once the final NOx emission limit is established pursuant to Appendix A, the parameters used to establish the final NOx emission limit shall not be enforceable or subject to stipulated penalties. Violation of an Emission Limit that is based on a 30-Day Rolling Average is a violation on every Day on which the average is based. Each subsequent Day of violation after a violation of a 30-Day Rolling Average Emission Limit is subject to the corresponding penalty per Day specified in Table 2, below. Where a violation of a 30-Day Rolling Average Emission Limit (for the same pollutant and from the same source) recurs within periods of less than thirty (30) Days, Defendant shall not pay a daily stipulated penalty for any Day of recurrence for which a stipulated penalty is already payable. Stipulated penalties may only be assessed once for a given Day within any averaging period for violation of any particular Emission Limit. Stipulated penalties for consecutive periods of violation of an Emission Limit shall be calculated based upon the violation of the Emission Limit for the same pollutant from the same Kiln.

Any other violation of the Consent $1,000 for each Day for each violation Decree 58. Subject to the provisions of Paragraph 57 above, stipulated penalties under this Section shall begin to accrue on the Day after performance is due or on the Day a violation occurs, whichever is applicable, and shall continue to accrue until performance is satisfactorily completed or until the violation ceases. Stipulated penalties shall accrue simultaneously for separate violations of this Consent Decree but each separate violation shall be subject to no more than one stipulated penalty. All stipulated penalties are subject to challenge by Defendant pursuant to Section XIV (Force Majeure). 59. Defendant shall pay any stipulated penalty within thirty (30) Days of receiving the United States' written demand. 60. The United States may, in the unreviewable exercise of its discretion, reduce or waive stipulated penalties otherwise due the United States under this Consent Decree. 61. Stipulated penalties shall accrue as provided in this Section, during any Dispute Resolution, but need not be paid until the following: a. If the dispute is resolved by agreement between the Parties or by a decision of the United States that is not appealed to the Court, Defendant shall pay accrued penalties determined to be owing, together with interest accruing from the 31st Day after the written demand in Paragraph 59, within 30 Days of the effective date of the agreement or the receipt of U.S. EPA's decision or order. b. If the dispute is appealed to the Court and the United States is the prevailing party, in whole or in part, as may be determined by the Court, Defendant shall pay all accrued penalties determined by the Court to be owing, together with interest accruing from the 31st Day after the written demand in Paragraph 59, within 60 Days of receiving the Court's decision or order, except as provided in Subparagraph c below. c. If any Party appeals the District Court's decision, Defendant shall pay all accrued penalties determined to be owing, together with interest accruing from the 31st Day after the written demand in Paragraph 59, within 15 Days of receiving the final appellate court decision. 62. Defendant shall pay stipulated penalties owing to the United States in the manner set forth in Paragraph 9 and with the confirmation notices to the persons specified in Paragraph 95, except that the transmittal letter shall state that the payment is for stipulated penalties and shall state for which violation(s) the penalties are being paid. 63. The United States may choose between (1) stipulated penalties and (2) any other right, remedy or sanction available to it, but not both. The payment of penalties and interest, if any, shall not alter in any way Defendant's obligation to complete the performance of the requirements of this Consent Decree. This Paragraph shall not limit the United States' ability to seek injunctive relief associated with such violations. 64. Defendant shall not deduct stipulated penalties paid under this Section in calculating their federal, state or local income tax. 65. If Defendant fails to pay stipulated penalties according to the terms of this Consent Decree, Defendant shall be liable for interest on such penalties, as provided for in 28 U.S.C. § 1961, accruing as of the date payment became due. Nothing in this Paragraph shall be construed to limit the United States from securing any remedy otherwise provided by law for Defendant's failure to pay any stipulated penalties. 66. Subject to the provisions of Section XVII (Effect of Settlement/Reservation of Rights) of this Consent Decree, the stipulated penalties provided for in this Consent Decree shall be in addition to any other rights, remedies, or sanctions available to the United States for Defendant's violation of this Consent Decree or applicable law. Where a violation of this Consent Decree is also a violation of the Clean Air Act, Defendant shall be allowed a dollar-for-dollar credit, for any stipulated penalties paid, against any statutory penalties imposed for such violations. SECTION XIV: FORCE MAJEURE 67. "Force Majeure" (for purposes of this Consent Decree) is defined as any event arising from causes beyond the control of Defendant, of any entity controlled by Defendant or Defendant's Contractors, that causes a delay or impediment to performance in complying with any obligation under this Consent Decree despite the Defendant's best efforts to fulfill the obligation. The requirement that the Defendant exercise best efforts to fulfill the obligation includes using best efforts to anticipate any potential Force Majeure event and best efforts to address the effects of any such event (a) as it is occurring and (b) after it has occurred to prevent or minimize any resulting delay and the effects of such event to the greatest extent possible. Force Majeure does not include the Defendant's financial inability to perform any obligation under this Consent Decree. Force Majeure may include Defendant's inability after demonstrating compliance with the requirements of Paragraphs 40 and 41 to obtain a permit or approval such that there is adequate time to install and Continuously Operate Control Technology required under this Consent Decree. 68. If any event occurs or has occurred that may delay the performance of any obligation under this Consent Decree, whether or not caused by a Force Majeure event, Defendant shall provide written notice or notice by electronic mail (email) to the representatives of U.S. EPA designated to receive notice pursuant to Section XIX (Notices) within seven (7) Business Days of when Defendant first knew that the event might cause a delay. Within 21 Days thereafter, Defendant shall provide in writing to U.S. EPA an explanation and description of the reasons for the delay; the anticipated duration of the delay; all actions taken or to be taken to prevent or minimize the delay; a schedule for implementation of any measures to be taken to prevent or mitigate the delay or the effect of the delay; Defendant's rationale for attributing such delay to a Force Majeure event if it intends to assert such a claim; and a statement as to whether, in the opinion of Defendant, such event may cause or contribute to an endangerment to public health, welfare or the environment. Defendant shall include with any notice all available documentation supporting the claim that the delay was attributable to a Force Majeure. Failure to comply with the above requirements shall preclude Defendant from asserting any claim of Force Majeure for that event for the period of time of such failure to comply, and for any additional delay caused by such failure. Defendant shall be deemed to know of any circumstance of which Defendant, any entity controlled by Defendant, or Defendant's Contractors knew or should have known. 69. If U.S. EPA agrees that the delay or anticipated delay is attributable to a Force Majeure event, the time for performance of the obligations under this Consent Decree that are affected by the Force Majeure event will be extended by U.S. EPA for such time as is necessary to complete those obligations. An extension of the time for performance of the obligations affected by the Force Majeure event shall not, of itself, extend the time for performance of any other obligation. U.S. EPA will notify Defendant in writing of the length of the extension, if any, for performance of the obligations affected by the Force Majeure event. 70. If U.S. EPA does not agree that the delay or anticipated delay has been or will be caused by a Force Majeure event, U.S. EPA will notify Defendant in writing of its decision. 71. If Defendant elects to invoke the dispute resolution procedures set forth in Section XV (Dispute Resolution), it shall do so no later than 15 Days after receipt of U.S. EPA's notice. In any such proceeding, Defendant shall have the burden of demonstrating by a preponderance of the evidence that the delay or anticipated delay has been or will be caused by a Force Majeure event, that the duration of the delay or the extension sought was or will be warranted under the circumstances, that best efforts were exercised to avoid and mitigate the effects of the delay, and that Defendant complied with the requirements of Paragraphs 67 and 68, above. If Defendant carries this burden, the delay at issue shall be deemed not to be a violation by Defendant of the affected obligation of this Consent Decree identified to U.S. EPA and the Court. SECTION XV: DISPUTE RESOLUTION 72. Unless otherwise expressly provided for in this Consent Decree, the dispute resolution procedures of this Section shall be the exclusive mechanism to resolve disputes arising under or with respect to this Consent Decree. Defendant's failure to seek resolution of a dispute under this Section shall preclude Defendant from raising any such issue as a defense to an action by the United States or Affected State to enforce any obligation of Defendant arising under this Consent Decree. 73. Informal Dispute Resolution for Emission Limit Setting Process under Appendix A. If Defendant invokes Dispute Resolution regarding an EPA-established alternative final 30-Day Rolling Average Emission Limit for NOx, Defendant shall promptly (within 15 days) initiate the process set forth in this Paragraph to hire an independent Contractor who will be tasked to analyze the 30-Day Rolling Average Emission Limits for NOx established by EPA and proposed by Defendant and to provide, for the benefit of both U.S. EPA and Defendant, the reports, analysis, and services identified in this Paragraph, below, by the specified deadlines. Defendant shall bear all costs associated with the Contractor's work up to $100,000, and shall provide the Contractor access to records, employees, contracts, and facilities which are reasonably necessary to complete the report required by this Paragraph. If costs to perform the work set forth in the Scope of Work (SOW) requirements described in this Paragraph are expected to be higher than $100,000, Defendant and U.S. EPA will, upon written mutual agreement, limit or modify the nature and/or scope of the work to be performed under this Paragraph to meet the expenditure limitation. For purposes of this Paragraph, "independent" shall mean a qualified professional with at least 5 years of experience relating to the operations of and/or emissions from cement kilns or similar sources and who has not previously been employed or retained by Defendant in any capacity (unless otherwise approved by U.S. EPA). a. Defendant shall submit to U.S. EPA for approval, the name and qualifications of a proposed Contractor for this engagement at the time it submits its Written Notice of Dispute in accordance with Section XIX (Notices). If U.S. EPA disapproves of the Contractor, Defendant is required to propose to U.S. EPA within 15 Days of the disapproval a different Contractor, also subject to U.S. EPA's approval. If U.S. EPA disapproves the second Contractor, U.S. EPA may choose and identify to Defendant the Contractor to be employed. Defendant shall enter into a contract with the Contractor, containing the SOW requirements in Paragraph 73.b, below (as modified to meet the expenditure limitations), within 14 Days of U.S. EPA's approval or final identification of the Contractor. b. As part of the contract, Defendant shall provide to the Contractor a SOW which will include a requirement or direction to: i. Analyze all the data collected under Appendix A, as well as the Demonstration Report, and proposed 30-Day Rolling Average Emission Limits for NOx; ii. Submit to U.S. EPA and Defendant, a report on the appropriate 30-day rolling average emission limit, consistent with the methodology set forth in and information collected through Appendix A, as applicable, based upon the injection rates and the operational parameters approved as part of the SNCR Design Reports and the SNCR Optimization Reports required by Appendix A, as applicable. The conclusions of this report shall be based on all of the information and data collected during the SNCR Optimization and Demonstration Periods, as applicable, as well as any additional site-specific information available to the Contractor. The report shall include a section on whether the data collected during the Demonstration Period is representative of normal operations of the unit, as well as a recommended final 30-Day Rolling Average Emission Limit for NOx using the protocol and procedures in Appendix A, as applicable; iii. Make available to U.S. EPA any and all data evaluated, and reveal all communications with Defendant in the course of work pursuant to the SOW. The Contractor shall also be tasked in the SOW to attend up to 15 hours of meetings specifically requested by U.S. EPA, to answer questions concerning any analysis or work undertaken pursuant to the SOW. Defendant may attend any such meeting between U.S. EPA and the Contractor. The SOW shall make clear that the Contractor is free to discuss its analysis, findings and the content of their report with U.S. EPA prior to the completion of the report; and iv. Complete the Contractor report within 45 Days from the time of the effective date of the contract. c. The results of the Contractor report will inform the parties in the process of engaging in informal dispute resolution on the proposed and final permit limit. 74. If the United States and Defendant are unable to reach agreement on a final 30-Day Rolling Average Emission Limit for NOx within 20 Days after receipt of the Contractor report by EPA referenced in the prior paragraph, Defendant may request formal dispute resolution under Paragraph 76 of this Consent Decree. The Contractor report shall be part of the Dispute Resolution record in any formal dispute proceedings under this Consent Decree. 75. Informal Dispute Resolution with Respect to All Other Disputes. Any dispute subject to Dispute Resolution under this Consent Decree shall first be the subject of informal negotiations. The dispute shall be considered to have arisen when Defendant sends the United States a written Notice of Dispute. Such Notice of Dispute shall state clearly the matter in dispute. The period of informal negotiations shall not exceed 30 Days from the date the dispute arises, unless that period is modified by written agreement. If the Parties cannot resolve a dispute by informal negotiations, then the position advanced by the United States shall be considered binding unless, within 30 Days after the conclusion of the informal negotiation period, Defendant invokes formal dispute resolution procedures as set forth below. 76. Formal Dispute Resolution. Defendant shall invoke formal dispute resolution procedures, within the time period provided in the preceding Paragraph, by serving on the United States a written Statement of Position regarding the matter in dispute. The Statement of Position shall include, but need not be limited to, any factual data, analysis, or opinion supporting Defendant's position and any supporting documentation relied upon by Defendant. 77. The United States shall serve its Statement of Position within 45 Days of receipt of Defendant's Statement of Position. The United States' Statement of Position shall include, but need not be limited to, any factual data, analysis, or opinion supporting that position and any supporting documentation relied upon by the United States. The United States' Statement of Position shall be binding on Defendant, unless Defendant files a motion for judicial review of the dispute in accordance with the following Paragraph. 78. Defendant may seek judicial review of the dispute by filing with the Court and serving on the United States, in accordance with Section XIX (Notices) of this Consent Decree, a motion requesting judicial resolution of the dispute. The motion must be filed within 20 Days of receipt of the United States Statement of Position pursuant to the preceding Paragraph. The motion shall contain a written statement of Defendant's position on the matter in dispute, including any supporting factual data, analysis, opinion, or documentation, and shall set forth the relief requested and any schedule within which the dispute must be resolved for orderly implementation of the Consent Decree. 79. The United States shall respond to Defendant's motion within the time period allowed by the Local Rules of this Court. Defendant may file a reply memorandum, to the extent permitted by the Local Rules. 80. Standard of Review. a. Disputes Concerning Matters Accorded Record Review. Except as otherwise provided in this Consent Decree, in any dispute brought under Paragraph 76 pertaining to the adequacy or appropriateness of plans, procedures to implement plans, schedules or any other items requiring approval by EPA under this Consent Decree; the adequacy of the performance of work undertaken pursuant to this Consent Decree; and all other disputes that are accorded review on the administrative record under applicable principles of administrative law, Defendant shall have the burden of demonstrating, based on the administrative record, that the position of the United States is arbitrary and capricious or otherwise not in accordance with law or the Consent Decree. b. Other Disputes. Except as otherwise provided in this Consent Decree, in any other dispute brought under Section XV (Dispute Resolution), Defendant shall bear the burden of demonstrating that its position complies with this Consent Decree. 81. The invocation of dispute resolution procedures under this Section shall not, by itself, extend, postpone, or affect in any way any obligation of Defendant under this Consent Decree, unless and until final resolution of the dispute so provides. Stipulated penalties with respect to the disputed matter shall continue to accrue from the first Day of noncompliance, but payment shall be stayed pending resolution of the dispute as provided in Paragraph 61. If Defendant does not prevail on the disputed issue, stipulated penalties shall be assessed and paid as provided in Section XIII (Stipulated Penalties). SECTION XVI: INFORMATION COLLECTION AND RETENTION 82. The United States and their representatives, including attorneys, contractors, and consultants, shall have the right of entry into the facility covered by this Consent Decree, at all reasonable times, upon presentation of credentials, to: a. monitor the progress of activities required under this Consent Decree; b. verify any data or information submitted to the United States in accordance with the terms of this Consent Decree; c. conduct performance testing; d. obtain documentary evidence, including photographs and similar data; and e. assess Defendant's compliance with this Consent Decree. 83. Upon request, Defendant shall provide U.S. EPA and its authorized representatives copies of analytical data from Kiln performance testing performed by Defendant. Upon request, U.S. EPA shall provide Defendant copies of analytical data from Kiln performance testing performed by U.S. EPA. 84. Until five years after the termination of this Consent Decree, Defendant shall retain, and shall instruct its Contractors and agents to preserve, all non-identical copies of all documents, records, or other information (including documents, records, or other information in electronic form) in its or its Contractors' or agents' possession or control, or that come into its or its Contractors' or agents' possession or control, and that relate in any manner to Defendant's performance of its obligations under this Consent Decree. This information-retention requirement shall apply regardless of any contrary corporate or institutional policies or procedures. At any time during this information-retention period, upon request by the United States Defendant shall provide copies of any documents, records, or other information required to be maintained under this Paragraph. 85. Defendant may also assert that information required to be provided under this Section is protected as Confidential Business Information ("CBI") under 40 C.F.R. Part 2. As to any information that Defendant seeks to protect as CBI, Defendant shall follow the procedures set forth in 40 C.F.R. Part 2. 86. This Consent Decree in no way limits or affects any right of entry and inspection, or any right to obtain information, held by the United States pursuant to applicable federal or state laws, regulations, or permits, nor does it limit or affect any duty or obligation of Defendant to maintain documents, records, or other information imposed by applicable federal or state laws, regulations, or permits.

For each Kiln, Defendant shall continue to collect the data specified in Paragraph III.2.a of Appendix A after the SNCR Optimization Period. 5. SNCR Optimization Report: a. Within 60 Days following the end of the SNCR Optimization Period for each Kiln, Defendant shall submit to EPA for approval pursuant to Section XI (Review and Approval of Submittals) of the Consent Decree an optimization report ("SNCR Optimization Report") for that Kiln. The Optimization Report shall: i. Demonstrate conformance with the SNCR Optimization Protocol for the Kiln and its associated SNCR system; ii. Include all data collected during the SNCR Optimization Periods; iii. Propose, for approval, consistent with the SNCR Optimization Protocol, the optimized operating parameters for the Kiln and the SNCR system to be maintained during the SNCR Demonstration Period; and iv. Propose steps to be taken to maintain an Ammonia Slip of between 2 and 6 ppm on a daily average basis or an alternative method of using Ammonia Slip data to control the SNCR operation during the Demonstration Period. b. In identifying the optimized state of each SNCR, including the injection rates of reagents, and the operating parameters for the Facility processes, Defendant may take into account energy, environmental, and economic impacts and other costs. c. The SNCR Optimization Report may also include a discussion of any problems encountered during the SNCR Optimization Period, and how that problem may impact the potential emission reductions (including the quantity of reagent slip at varying injection rates and/or the possible observance of a detached plume above the Stack). d. In the event Defendant determines, prior to the expiration of the SNCR Optimization Period, that its ability to optimize the Kiln and/or its SNCR system will be affected by potential impairments to product quality, Kiln system reliability or increased emissions of other pollutants, then Defendant shall promptly advise EPA of this determination, and include these considerations as part of its recommendation in its SNCR Optimization Report. 6. SNCR Demonstration Period: a. The SNCR Demonstration Period for each Kiln shall commence within 7 days after Defendant's receipt of the final approval by EPA of the SNCR Optimization Report for the relevant Kiln. b. The SNCR Demonstration Period shall last 270 Operating Days. During the SNCR Demonstration Period, the Kiln shall be operated consistent with the optimized operations of the Facility's processes and the SNCR system as approved by EPA as part of the SNCR Optimization Report. c. Subject to Section XV (Dispute Resolution) and through written notice to Defendant, EPA may itself extend or reopen the SNCR Demonstration Period based upon a determination that additional data is needed to be able to adequately establish an emission limitation. d. If evidence arises during the SNCR Demonstration Period that product quality, or Kiln system reliability is impaired, then Defendant may, upon notice to, and approval by, EPA, temporarily modify Kiln operation and the SNCR system to mitigate the impairment and request that EPA suspend or extend the SNCR Demonstration Period for further technical evaluation of the effects of process optimization on the Kiln or SNCR system or, alternatively, permanently modify the manner of operation of the Kiln or SNCR system to mitigate the effects. e. During the SNCR Demonstration Period for each Kiln, Defendant shall collect the same data as required in Paragraph III.2.a of Appendix A. 7. SNCR Demonstration Report: a. Within 60 Days following completion of the SNCR Demonstration Period for each Kiln and its associated SNCR, Defendant shall submit a demonstration report to EPA ("SNCR Demonstration Report") for that Kiln. The SNCR Demonstration Report shall include all of the data collected during the SNCR Demonstration Period and the proposed 30-Day Rolling Average Emission Limit for NOx for each Kiln. b. For the purposes of the SNCR Demonstration Report: i. The 30-Day Rolling Average Emission Limit for NOx for each Kiln shall be based upon an analysis of CEMS data and clinker production data collected during the SNCR Demonstration Period while the Facility's processes and SNCR system parameters were optimized consistent with the SNCR Optimization Report, Appendix A.IV.5 of the Consent Decree. ii. Total pounds of NOx emitted during an individual Operating Day will be calculated from collected CEMS data for that Operating Day. iii. Hours or days when there is no Kiln Operation may be excluded from the calculation in Paragraph IV.7.c of Appendix A below. However, Defendant shall provide an explanation in the SNCR Demonstration Report for any data excluded and include the excluded data in the Demonstration Report. iv. All NOx data when hourly Ammonia Slip is less than 2 ppm or greater than 6 ppm may be used for daily NOx average calculation. For any days where the daily Ammonia Slip averages less than 2 ppm or greater than 6 ppm, Defendant shall provide justification for use of that data for use in determination of the 30-Day Rolling Average Emission Limit for NOx for each Kiln. EPA reserves the right to eliminate any data outside the parameters of the Optimization Report from the final 30-Day Rolling Average Emission Limit. c. The final 30-Day Rolling Average Emission Limit for NOx for each Kiln shall be calculated in accordance with the following formula: X = μ + 1.65σ where: X = 30-Day Rolling Average Emission Limit (lbs/Ton of clinker) μ = arithmetic mean of all of the 30-Day rolling averages σ = standard deviation of all of the 30-Day rolling averages, as calculated in the following manner:

d. EPA shall either approve the proposed 30-Day Rolling Average Emission Limits for NOx or establish an alternative 30-Day Rolling Average Emission Limits. If EPA establishes an alternative 30-Day Rolling Average Emission Limit for NOx for one or both of the Kilns, Defendant will begin to meet the alternative 30-Day Rolling Average Emission Limit for NOx within 30 days of receiving notice of the limits from EPA, unless Defendant invokes dispute resolution according to the Section XV (Dispute Resolution) provisions of the Consent Decree in which case the final NOx limit shall be the 30-Day Rolling Average agreed to by the Parties at the conclusion of Informal Dispute Resolution. If Informal Dispute Resolution does not resolve the dispute, Defendant shall comply with its Proposed final NOx emissions limit until a final NOx Emissions Limit is determined by the Court. e. Subsequent to EPA's approval of the final 30-Day Rolling Average Emission Limits for NOx, Defendant shall have the right to use any type or quantity of reagent, provided that Defendant continues to comply with the 30-Day Rolling Average Emission Limit for NOx. f. Supporting data required to be submitted under this Appendix A may contain information relative to Kiln operation and production that Defendant may consider to be proprietary. In such a situation, Defendant may submit the information to EPA as CBI, subject to the provisions of 40 C.F.R. Part 2. g. If the final 30-Day Rolling Average Emission Limit for NOx is established at 40% or more below Baseline NOx Emissions, no further action shall be required under this Appendix A.
