Permitted Activities 1 . 1 This source is a municipal solid waste disposal facility with a design capacity of 11 ,330,917 Megagrams of non-hazardous solid waste (as defined in 6 CCR 1007-2) . The landfill began accepting waste on February 3 , 1992 . Decomposing waste encapsulated within the landfill produces a gas that is primarily composed of methane and carbon dioxide. Emissions of non-methane organic compounds (NMOC) , Volatile Organic Compounds (VOC) and Hazardous Air Pollutants (HAP) also result from the decomposition of solid waste placed in the landfill . A voluntary gas collection and control system is in place at this facility. Collected landfill gas is sent to a utility flare . Combustion emissions from the flare include Particulate Matter (PM, PM10, and PM25) emissions, Sulfur Dioxide (SO2), Nitrogen Oxides (NOx), and Carbon Monoxide (CO) . Fugitive particulate emissions are emitted from the following landfill activities : material transfer to and from storage piles, disturbed areas, wind erosion of storage piles, waste dumping, and vehicle traffic on paved and unpaved roads. The facility is located approximately nine miles east of 1 -25 on Route 14 where it intersects Weld County Road 25 near Ault. This facility is located in an area classified as attainment for all pollutants except ozone . It is classified as non-attainment for the 8-hr ozone standard and is part of the 8-hr Ozone Control Area as defined in Regulation No . 7, Section II .A. 1 . There is one affected state within 50 miles of the plant : Wyoming. The following Federal Class I designated areas are within 100 kilometers of the plant : Rocky Mountain National Park and Rawah Wilderness Area. 1 .2 Until such time as this permit expires or is modified or revoked, the permittee is allowed to discharge air pollutants from this facility in accordance with the requirements, limitations, and conditions of this permit. 1 . 3 The Operating Permit incorporates the applicable requirements contained in the underlying construction permits, and does not affect those applicable requirements, except as modified during review of the application or as modified subsequent to permit issuance using the modification procedures found in Regulation No . 3 , Part C .

Colorado Operating Permit North Weld Landfill Permit# 97OPWE181 Page 25 3. Common Provisions Common Provisions Regulation, 5 CCR 1001-2 §§ II.A., II.B., II.C., II.E., II.F., II.1, and II.J a. To Control Emissions Leaving Colorado When emissions generated from sources in Colorado cross the State boundary line, such emissions shall not cause the air quality standards of the receiving State to be exceeded,provided reciprocal action is taken by the receiving State. b. Emission Monitoring Requirements The Division may require owners or operators of stationary air pollution sources to install, maintain, and use instrumentation to monitor and record emission data as a basis for periodic reports to the Division. c. Performance Testing The owner or operator of any air pollution source shall, upon request of the Division, conduct performance test(s) and furnish the Division a written report of the results of such test(s) in order to determine compliance with applicable emission control regulations. Performance test(s) shall be conducted and the data reduced in accordance with the applicable reference test methods unless the Division: (i) specifies or approves, in specific cases,the use of a test method with minor changes in methodology; (ii) approves the use of an equivalent method; (iii) approves the use of an alternative method the results of which the Division has determined to be adequate for indicating where a specific source is in compliance; or (iv) waives the requirement for performance test(s)because the owner or operator of a source has demonstrated by other means to the Division's satisfaction that the affected facility is in compliance with the standard.Nothing in this paragraph shall be construed to abrogate the Commission's or Division's authority to require testing under the Colorado Revised Statutes, Title 25, Article 7, and pursuant to regulations promulgated by the Commission. Compliance test(s) shall be conducted under such conditions as the Division shall specify to the plant operator based on representative performance of the affected facility. The owner or operator shall make available to the Division such records as may be necessary to determine the conditions of the performance test(s). Operations during period of startup, shutdown, and malfunction shall not constitute representative conditions of performance test(s)unless otherwise specified in the applicable standard. The owner or operator of an affected facility shall provide the Division thirty days prior notice of the performance test to afford the Division the opportunity to have an observer present. The Operating Permit 97OPWE181 First Issued: March 1,2000 Renewed: Air Pollution Control Division Waste Management Disposal Services of Colorado, Inc. Colorado Operating Permit North Weld Landfill Permit# 97OPWE181 Page 26 Division may waive the thirty day notice requirement provided that arrangements satisfactory to the Division are made for earlier testing. The owner or operator of an affected facility shall provide, or cause to be provided,performance testing facilities as follows: (i) Sampling ports adequate for test methods applicable to such facility; (ii) Safe sampling platform(s); (iii) Safe access to sampling platform(s); and (iv) Utilities for sampling and testing equipment. Each performance test shall consist of at least three separate runs using the applicable test method. Each run shall be conducted for the time and under the conditions specified in the applicable standard. For the purpose of determining compliance with an applicable standard,the arithmetic mean of results of at least three runs shall apply. In the event that a sample is accidentally lost or conditions occur in which one of the runs must be discontinued because of forced shutdown, failure of an irreplaceable portion of the sample train, extreme meteorological conditions, or other circumstances beyond the owner or operator's control, compliance may, upon the Division's approval, be determined using the arithmetic mean of the results of the two other runs. Nothing in this section shall abrogate the Division's authority to conduct its own performance test(s) if so warranted. d. Affirmative Defense Provision for Excess Emissions during Malfunctions An affirmative defense to a claim of violation under these regulations is provided to owners and operators for civil penalty actions for excess emissions during periods of malfunction. To establish the affirmative defense and to be relieved of a civil penalty in any action to enforce an applicable requirement,the owner or operator of the facility must meet the notification requirements below in a timely manner and prove by a preponderance of evidence that: (i) The excess emissions were caused by a sudden,unavoidable breakdown of equipment, or a sudden, unavoidable failure of a process to operate in the normal or usual manner, beyond the reasonable control of the owner or operator; (ii) The excess emissions did not stem from any activity or event that could have reasonably been foreseen and avoided, or planned for, and could not have been avoided by better operation and maintenance practices; (iii) Repairs were made as expeditiously as possible when the applicable emission limitations were being exceeded; (iv) The amount and duration of the excess emissions (including any bypass)were minimized to the maximum extent practicable during periods of such emissions; Operating Permit 97OPWE181 First Issued: March 1, 2000 Renewed: Air Pollution Control Division Waste Management Disposal Services of Colorado, Inc. Colorado Operating Permit North Weld Landfill Permit#97OPWE181 Page 27 (v) All reasonably possible steps were taken to minimize the impact of the excess emissions on ambient air quality; (vi) All emissions monitoring systems were kept in operation (if at all possible); (vii) The owner or operator's actions during the period of excess emissions were documented by properly signed, contemporaneous operating logs or other relevant evidence; (viii) The excess emissions were not part of a recurring pattern indicative of inadequate design, operation, or maintenance; (ix) At all times,the facility was operated in a manner consistent with good practices for minimizing emissions. This section is intended solely to be a factor in determining whether an affirmative defense is available to an owner or operator, and shall not constitute an additional applicable requirement; and (x) During the period of excess emissions,there were no exceedances of the relevant ambient air quality standards established in the Commissions' Regulations that could be attributed to the emitting source. The owner or operator of the facility experiencing excess emissions during a malfunction shall notify the division verbally as soon as possible, but no later than noon of the Division's next working day, and shall submit written notification following the initial occurrence of the excess emissions by the end of the source's next reporting period. The notification shall address the criteria set forth above. The Affirmative Defense Provision contained in this section shall not be available to claims for injunctive relief. The Affirmative Defense Provision does not apply to failures to meet federally promulgated performance standards or emission limits, including, but not limited to, new source performance standards and national emission standards for hazardous air pollutants. The affirmative defense provision does not apply to state implementation plan (sip) limits or permit limits that have been set taking into account potential emissions during malfunctions, including, but not necessarily limited to, certain limits with 30-day or longer averaging times, limits that indicate they apply during malfunctions, and limits that indicate they apply at all times or without exception. e. Circumvention Clause A person shall not build, erect, install, or use any article, machine, equipment, condition, or any contrivance,the use of which,without resulting in a reduction in the total release of air pollutants to the atmosphere, reduces or conceals an emission which would otherwise constitute a violation of this regulation.No person shall circumvent this regulation by using more openings than is considered normal practice by the industry or activity in question. Operating Permit 97OPWE181 First Issued: March 1, 2000 Renewed: Air Pollution Control Division Waste Management Disposal Services of Colorado, Inc. Colorado Operating Permit North Weld Landfill Permit#97OPWE181 Page 28 f. Compliance Certifications For the purpose of submitting compliance certifications or establishing whether or not a person has violated or is in violation of any standard in the Colorado State Implementation Plan, nothing in the Colorado State Implementation Plan shall preclude the use, including the exclusive use, of any credible evidence or information, relevant to whether a source would have been in compliance with applicable requirements if the appropriate performance or compliance test or procedure had been performed. Evidence that has the effect of making any relevant standard or permit term more stringent shall not be credible for proving a violation of the standard or permit term. When compliance or non-compliance is demonstrated by a test or procedure provided by permit or other applicable requirement,the owner or operator shall be presumed to be in compliance or non-compliance unless other relevant credible evidence overcomes that presumption. g. Affirmative Defense Provision for Excess Emissions During Startup and Shutdown An affirmative defense is provided to owners and operators for civil penalty actions for excess emissions during periods of startup and shutdown. To establish the affirmative defense and to be relieved of a civil penalty in any action to enforce an applicable requirement,the owner or operator of the facility must meet the notification requirements below in a timely manner and prove by a preponderance of the evidence that: (i) The periods of excess emissions that occurred during startup and shutdown were short and infrequent and could not have been prevented through careful planning and design; (ii) The excess emissions were not part of a recurring pattern indicative of inadequate design, operation or maintenance; (iii) If the excess emissions were caused by a bypass (an intentional diversion of control equipment),then the bypass was unavoidable to prevent loss of life,personal injury, or severe property damage; (iv) The frequency and duration of operation in startup and shutdown periods were minimized to the maximum extent practicable; (v) All possible steps were taken to minimize the impact of excess emissions on ambient air quality; (vi) All emissions monitoring systems were kept in operation(if at all possible); (vii) The owner or operator's actions during the period of excess emissions were documented by properly signed, contemporaneous operating logs or other relevant evidence; and, (viii) At all times,the facility was operated in a manner consistent with good practices for minimizing emissions. This subparagraph is intended solely to be a factor in determining whether an affirmative defense is available to an owner or operator, and shall not constitute an additional applicable requirement. Operating Permit 97OPWE181 First Issued: March 1, 2000 Renewed: Air Pollution Control Division Waste Management Disposal Services of Colorado, Inc. Colorado Operating Permit North Weld Landfill Permit# 97OPWE181 Page 29 The owner or operator of the facility experiencing excess emissions during startup and shutdown shall notify the Division verbally as soon as possible, but no later than two (2)hours after the start of the next working day, and shall submit written quarterly notification following the initial occurrence of the excess emissions. The notification shall address the criteria set forth above. The Affirmative Defense Provision contained in this section shall not be available to claims for injunctive relief. The Affirmative Defense Provision does not apply to State Implementation Plan provisions or other requirements that derive from new source performance standards or national emissions standards for hazardous air pollutants, or any other federally enforceable performance standard or emission limit with an averaging time greater than twenty-four hours. In addition, an affirmative defense cannot be used by a single source or small group of sources where the excess emissions have the potential to cause an exceedance of the ambient air quality standards or Prevention of Significant Deterioration (PSD) increments. In making any determination whether a source established an affirmative defense,the Division shall consider the information within the notification required above and any other information the Division deems necessary, which may include, but is not limited to,physical inspection of the facility and review of documentation pertaining to the maintenance and operation of process and air pollution control equipment. 4. Compliance Requirements Regulation No. 3, 5 CCR 1001-5,Part C, §§ III.C.9., V.C.11. & 16.d. and § 25-7-122.1(2), C.R.S. a. The permittee must comply with all conditions of the Operating Permit. Any permit noncompliance relating to federally-enforceable terms or conditions constitutes a violation of the federal act, as well as the state act and Regulation No. 3. Any permit noncompliance relating to state-only terms or conditions constitutes a violation of the state act and Regulation No. 3, shall be enforceable pursuant to state law, and shall not be enforceable by citizens under § 304 of the federal act. Any such violation of the federal act,the state act or regulations implementing either statute is grounds for enforcement action, for permit termination, revocation and reissuance or modification or for denial of a permit renewal application. b. It shall not be a defense for a permittee in an enforcement action or a consideration in favor of a permittee in a permit termination,revocation or modification action or action denying a permit renewal application that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of the permit. c. The permit may be modified, revoked, reopened, and reissued, or terminated for cause. The filing of any request by the permittee for a permit modification, revocation and reissuance, or termination, or any notification of planned changes or anticipated noncompliance does not stay any permit condition, except as provided in §§ X. and XI. of Regulation No. 3,Part C. d. The permittee shall furnish to the Air Pollution Control Division,within a reasonable time as specified by the Division, any information that the Division may request in writing to determine Operating Permit 97OPWE181 First Issued: March 1,2000 Renewed: Air Pollution Control Division Waste Management Disposal Services of Colorado, Inc. Colorado Operating Permit North Weld Landfill Permit# 97OPWE181 Page 30 whether cause exists for modifying,revoking and reissuing, or terminating the permit or to determine compliance with the permit. Upon request,the permittee shall also furnish to the Division copies of records required to be kept by the permittee, including information claimed to be confidential. Any information subject to a claim of confidentiality shall be specifically identified and submitted separately from information not subject to the claim. e. Any schedule for compliance for applicable requirements with which the source is not in compliance at the time of permit issuance shall be supplemental, and shall not sanction noncompliance with,the applicable requirements on which it is based. f. For any compliance schedule for applicable requirements with which the source is not in compliance at the time of permit issuance,the permittee shall submit, at least every 6 months unless a more frequent period is specified in the applicable requirement or by the Air Pollution Control Division,progress reports which contain the following: (i) dates for achieving the activities,milestones, or compliance required in the schedule for compliance, and dates when such activities,milestones, or compliance were achieved; and (ii) an explanation of why any dates in the schedule of compliance were not or will not be met, and any preventive or corrective measures adopted. g. The permittee shall not knowingly falsify,tamper with, or render inaccurate any monitoring device or method required to be maintained or followed under the terms and conditions of the Operating Permit. 5. Emergency Provisions Regulation No. 3, 5 CCR 1001-5,Part C, § VII.E An emergency means any situation arising from sudden and reasonably unforeseeable events beyond the control of the source, including acts of God,which situation requires immediate corrective action to restore normal operation, and that causes the source to exceed the technology-based emission limitation under the permit due to unavoidable increases in emissions attributable to the emergency. "Emergency" does not include noncompliance to the extent caused by improperly designed equipment, lack of preventative maintenance, careless or improper operation, or operator error. An emergency constitutes an affirmative defense to an enforcement action brought for noncompliance with a technology-based emission limitation if the permittee demonstrates,through properly signed, contemporaneous operating logs, or other relevant evidence that: a. an emergency occurred and that the permittee can identify the cause(s) of the emergency; b. the permitted facility was at the time being properly operated; c. during the period of the emergency the permittee took all reasonable steps to minimize levels of emissions that exceeded the emission standards, or other requirements in the permit; and Operating Permit 97OPWE181 First Issued: March 1,2000 Renewed: Air Pollution Control Division Waste Management Disposal Services of Colorado, Inc. Colorado Operating Permit North Weld Landfill Permit#97OPWE181 Page 31 d. the permittee submitted oral notice of the emergency to the Air Pollution Control Division no later than noon of the next working day following the emergency, and followed by written notice within one month of the time when emissions limitations were exceeded due to the emergency. This notice must contain a description of the emergency, any steps taken to mitigate emissions, and corrective actions taken. This emergency provision is in addition to any emergency or malfunction provision contained in any applicable requirement. 6.

With prior approval of the Air Pollution Control Division,the permittee may maintain any of the above records in a computerized form. c. Permittees must retain records of all required monitoring data and support information for the most recent twelve (12)month period, as well as compliance certifications for the past five (5) years on-site at all times. A permittee shall make available for the Air Pollution Control Division's review all other records of required monitoring data and support information required to be retained by the permittee upon 48 hours advance notice by the Division. d. The permittee shall submit to the Air Pollution Control Division all reports of any required monitoring at least every six (6)months, unless an applicable requirement,the compliance assurance monitoring rule, or the Division requires submission on a more frequent basis. All instances of deviations from any permit requirements must be clearly identified in such reports. e. The permittee shall file an Air Pollutant Emissions Notice("APEN")prior to constructing, modifying, or altering any facility,process, activity which constitutes a stationary source from which air pollutants are or are to be emitted, unless such source is exempt from the APEN filing requirements of Regulation No. 3,Part A, § II.D. A revised APEN shall be filed annually whenever a significant change in emissions, as defined in Regulation No. 3,Part A, § II.C.2., occurs;whenever there is a change in owner or operator of any facility,process, or activity; whenever new control equipment is installed; whenever a different type of control equipment replaces an existing type of control equipment; whenever a permit limitation must be modified; or before the APEN expires. An APEN is valid for a period of five years. The five-year period recommences when a revised APEN is received by the Air Pollution Control Division. Revised APENs shall be submitted no later than 30 days before the five-year term expires. Permittees Operating Permit 97OPWE181 First Issued: March 1, 2000 Renewed: Air Pollution Control Division Waste Management Disposal Services of Colorado, Inc. Colorado Operating Permit North Weld Landfill Permit# 97OPWE181 Page 36 submitting revised APENs to inform the Division of a change in actual emission rates must do so by April 30 of the following year. Where a permit revision is required,the revised APEN must be filed along with a request for permit revision. APENs for changes in control equipment must be submitted before the change occurs. Annual fees are based on the most recent APEN on file with the Division. 23. Reopenings for Cause Regulation No. 3, 5 CCR 1001-5, Part C, § XIII. a. The Air Pollution Control Division shall reopen, revise, and reissue Operating Permits;permit reopenings and reissuance shall be processed using the procedures set forth in Regulation No. 3, Part C, § III., except that proceedings to reopen and reissue permits affect only those parts of the permit for which cause to reopen exists. b. The Division shall reopen a permit whenever additional applicable requirements become applicable to a major source with a remaining permit term of three or more years,unless the effective date of the requirements is later than the date on which the permit expires, or unless a general permit is obtained to address the new requirements; whenever additional requirements (including excess emissions requirements) become applicable to an affected source under the acid rain program; whenever the Division determines the permit contains a material mistake or that inaccurate statements were made in establishing the emissions standards or other terms or conditions of the permit; or whenever the Division determines that the permit must be revised or revoked to assure compliance with an applicable requirement. c. The Division shall provide 30 days' advance notice to the permittee of its intent to reopen the permit, except that a shorter notice may be provided in the case of an emergency. d. The permit shield shall extend to those parts of the permit that have been changed pursuant to the reopening and reissuance procedure. 24. Section 502(b)(10) Changes Regulation No. 3, 5 CCR 1001-5,Part C, § XII.A. The permittee shall provide a minimum 7-day advance notification to the Air Pollution Control Division and to the Environmental Protection Agency at the addresses listed in Appendix D of this Permit.

The permittee shall not make a significant modification required to be reviewed under Regulation No. 3, Part B ("Construction Permit" requirements)without first receiving a construction permit. The permittee shall submit a complete Operating Permit application or application for an Operating Permit revision for any new or modified source within twelve months of commencing operation,to the address listed in Item 1 in Appendix D of this permit. If the permittee chooses to use the "Combined Construction/Operating Permit" application procedures of Regulation No. 3, Part C,then the Operating Permit must be received prior to commencing construction of the new or modified source. 27. Special Provisions Concerning the Acid Rain Program Regulation No. 3, 5 CCR 1001-5, Part C, §§ V.C.1.b. & 8 a. Where an applicable requirement of the federal act is more stringent than an applicable requirement of regulations promulgated under Title IV of the federal act, 40 Code of Federal Regulations (CFR)Part 72,both provisions shall be incorporated into the permit and shall be federally enforceable. b. Emissions exceeding any allowances that the source lawfully holds under Title IV of the federal act or the regulations promulgated thereunder, 40 CFR Part 72, are expressly prohibited. 28. Transfer or Assignment of Ownership Regulation No. 3, 5 CCR 1001-5, Part C, II.C. No transfer or assignment of ownership of the Operating Permit source will be effective unless the prospective owner or operator applies to the Air Pollution Control Division on Division-supplied Administrative Permit Amendment forms, for reissuance of the existing Operating Permit. No administrative permit shall be complete until a written agreement containing a specific date for transfer of permit, responsibility, coverage, and liability between the permittee and the prospective owner or operator has been submitted to the Division. 29. Volatile Organic Compounds Regulation No. 7, 5 CCR 1001-9, §§ III &V.

If a conviction of any person under this paragraph is for a violation committed after a first conviction of such person under this paragraph,the maximum punishment shall be doubled with respect to both the fine and imprisonment. The permittee must comply with all conditions of this operating permit. Any permit noncompliance constitutes a violation of the Act and is grounds for enforcement action; for permit termination,revocation and reissuance, or modification; or for denial of a permit renewal application. The Part 70 Operating Permit program requires three types of reports to be filed for all permits. All required reports must be certified by a responsible official. Report#1: Monitoring Deviation Report(due at least every six months) For purposes of this operating permit, the Division is requiring that the monitoring reports are due every six months unless otherwise noted in the permit. All instances of deviations from permit monitoring requirements must be clearly identified in such reports. For purposes of this operating permit,monitoring means any condition determined by observation, by data from any monitoring protocol, or by any other monitoring which is required by the permit as well as the recordkeeping associated with that monitoring. This would include, for example, fuel use or process rate monitoring, fuel analyses, and operational or control device parameter monitoring. Report#2: Permit Deviation Report(must be reported "promptly") In addition to the monitoring requirements set forth in the permits as discussed above, each and every requirement of the permit is subject to deviation reporting. The reports must address deviations from permit requirements, including those attributable to malfunctions as defined in this Appendix,the probable cause of Operating Permit 97OPWE181 First Issued: March 1, 2000 Renewed: Air Pollution Control Division Colorado Operating Permit Appendix B Monitoring and Permit Deviation Report Page 43 such deviations, and any corrective actions or preventive measures taken. All deviations from any term or condition of the permit are required to be summarized or referenced in the annual compliance certification. For purposes of this operating permit, "malfunction" shall refer to both emergency conditions and malfunctions. Additional discussion on these conditions is provided later in this Appendix. For purposes of this operating permit, the Division is requiring that the permit deviation reports are due as set forth in General Condition 21. Where the underlying applicable requirement contains a definition of prompt or otherwise specifies a time frame for reporting deviations,that definition or time frame shall govern. For example, quarterly Excess Emission Reports required by an NSPS or Regulation No. 1, Section IV. In addition to the monitoring deviations discussed above, included in the meaning of deviation for the purposes of this operating permit are any of the following: (1) A situation where emissions exceed an emission limitation or standard contained in the permit; (2) A situation where process or control device parameter values demonstrate that an emission limitation or standard contained in the permit has not been met; (3) A situation in which observations or data collected demonstrates noncompliance with an emission limitation or standard or any work practice or operating condition required by the permit; or, (4) A situation in which an excursion or exceedance as defined in 40CFR Part 64 (the Compliance Assurance Monitoring (CAM)Rule)has occurred. (only if the emission point is subject to CAM) For reporting purposes,the Division has combined the Monitoring Deviation Report with the Permit Deviation Report. All deviations shall be reported using the following codes: 1 =Standard: When the requirement is an emission limit or standard 2 =Process: When the requirement is a production/process limit 3=Monitor: When the requirement is monitoring 4=Test: When the requirement is testing 5=Maintenance: When required maintenance is not performed 6=Record: When the requirement is recordkeeping 7=Report: When the requirement is reporting 8=CAM: A situation in which an excursion or exceedance as defined in 40CFR Part 64 (the Compliance Assurance Monitoring(CAM) Rule) has occurred. 9=Other: When the deviation is not covered by any of the above categories Report#3: Compliance Certification (annually,as defined in the permit) Submission of compliance certifications with terms and conditions in the permit, including emission limitations, standards, or work practices, is required not less than annually. Operating Permit 97OPWE181 First Issued: March 1, 2000 Renewed: Air Pollution Control Division Colorado Operating Permit Appendix B Monitoring and Permit Deviation Report Page 44 Compliance Certifications are intended to state the compliance status of each requirement of the permit over the certification period. They must be based, at a minimum, on the testing and monitoring methods specified in the permit that were conducted during the relevant time period. In addition, if the owner or operator knows of other material information(i.e. information beyond required monitoring that has been specifically assessed in relation to how the information potentially affects compliance status),that information must be identified and addressed in the compliance certification. The compliance certification must include the following: • The identification of each term or condition of the permit that is the basis of the certification; • Whether or not the method(s)used by the owner or operator for determining the compliance status with each permit term and condition during the certification period was the method(s) specified in the permit. Such methods and other means shall include, at a minimum,the methods and means required in the permit. If necessary,the owner or operator also shall identify any other material information that must be included in the certification to comply with section 113(c)(2)of the Federal Clean Air Act, which prohibits knowingly making a false certification or omitting material information; • The status of compliance with the terms and conditions of the permit, and whether compliance was continuous or intermittent. The certification shall identify each deviation and take it into account in the compliance certification. Note that not all deviations are considered violations.' • Such other facts as the Division may require, consistent with the applicable requirements to which the source is subject, to determine the compliance status of the source. The Certification shall also identify as possible exceptions to compliance any periods during which compliance is required and in which an excursion or exceedance as defined under 40 CFR Part 64 (the Compliance Assurance Monitoring(CAM) Rule)has occurred. (only for emission points subject to CAM) Note the requirement that the certification shall identify each deviation and take it into account in the compliance certification. Previously submitted deviation reports, including the deviation report submitted at the time of the annual certification,may be referenced in the compliance certification. • ' For example, given the various emissions limitations and monitoring requirements to which a source may be subject, a deviation from one requirement may not be a deviation under another requirement which recognizes an exception and/or special circumstances relating to that same event. Operating Permit 97OPWE181 First Issued: March 1, 2000 Renewed: Air Pollution Control Division Colorado Operating Permit Appendix B Monitoring and Permit Deviation Report Page 45 Startup, Shutdown, Malfunctions and Emergencies, Understanding the application of Startup, Shutdown, Malfunctions and Emergency Provisions, is very important in both the deviation reports and the annual compliance certifications. Startup, Shutdown, and Malfunctions Please note that exceedances of some New Source Performance Standards (NSPS)and Maximum Achievable Control Technology(MACT) standards that occur during Startup, Shutdown or Malfunctions may not be considered to be non-compliance since emission limits or standards often do not apply unless specifically stated in the NSPS. Such exceedances must,however, be reported as excess emissions per the NSPS/MACT rules and would still be noted in the deviation report. In regard to compliance certifications,the permittee should be confident of the information related to those deviations when making compliance determinations since they are subject to Division review. The concepts of Startup, Shutdown and Malfunctions also exist for Best Available Control Technology(BACT) sources, but are not applied in the same fashion as for NSPS and MACT sources. Emergency Provisions Under the Emergency provisions of Part 70 certain operational conditions may act as an affirmative defense against enforcement action if they are properly reported. DEFINITIONS Malfunction (NSPS)means any sudden, infrequent, and not reasonably preventable failure of air pollution control equipment,process equipment, or a process to operate in a normal or usual manner. Failures that are caused in part by poor maintenance or careless operation are not malfunctions. Malfunction (SIP) means any sudden and unavoidable failure of air pollution control equipment or process equipment or unintended failure of a process to operate in a normal or usual manner. Failures that are primarily caused by poor maintenance, careless operation, or any other preventable upset condition or preventable equipment breakdown shall not be considered malfunctions. Emergency means any situation arising from sudden and reasonably unforeseeable events beyond the control of the source, including acts of God,which situation requires immediate corrective action to restore normal operation, and that causes the source to exceed a technology-based emission limitation under the permit, due to unavoidable increases in emissions attributable to the emergency. An emergency shall not include noncompliance to the extent caused by improperly designed equipment, lack of preventative maintenance, careless or improper operation, or operator error.

FACILITY NAME: Waste Management Disposal Services of Colorado, Inc.—North Weld Landfill OPERATING PERMIT NO: 97OPEP181 REPORTING PERIOD: I. Facility Status During the entire reporting period,this source was in compliance with ALL terms and conditions contained in the Permit, each term and condition of which is identified and included by this reference. The method(s) used to determine compliance is/are the method(s) specified in the Permit. With the possible exception of the deviations identified in the table below, this source was in compliance with all terms and conditions contained in the Permit, each term and condition of which is identified and included by this reference, during the entire reporting period. The method used to determine compliance for each term and condition is the method specified in the Permit,unless otherwise indicated and described in the deviation report(s). Note that not all deviations are considered violations.

Mark both columns if both apply. 2 Note whether the method(s)used to determine the compliance status with each term and condition was the method(s)specified in the permit. If it was not,mark "no"and attach additional information/explanation. Operating Permit 97OPWE181 First Issued: March 1, 2000 Renewed: Air Pollution Control Division Colorado Operating Permit Appendix C Compliance Certification Report Page 51 Note whether the compliance status with each term and condition provided was continuous or intermittent. "Intermittent Compliance"can mean either that noncompliance has occurred or that the owner or operator has data sufficient to certify compliance only on an intermittent basis. Certification of intermittent compliance therefore does not necessarily mean that any noncompliance has occurred. NOTE: The Periodic Monitoring requirements of the Operating Permit program rule are intended to provide assurance that even in the absence of a continuous system of monitoring the Title V source can demonstrate whether it has operated in continuous compliance for the duration of the reporting period. Therefore,if a source 1)conducts all of the monitoring and recordkeeping required in its permit,even if such activities are done periodically and not continuously,and if 2)such monitoring and recordkeeping does not indicate non-compliance,and if 3)the Responsible Official is not aware of any credible evidence that indicates non- compliance,then the Responsible Official can certify that the emission point(s)in question were in continuous compliance during the applicable time period. 4 Compliance status for these sources shall be based on a reasonable inquiry using readily available information.

II. Description of Source 123/0209 Page 1 of 11 Waste Management Disposal Services of Colorado—North Weld Landfill Operating Permit No. 97OPWE181 Technical Review Document—Second Renewal Operating Permit This source is a municipal solid waste disposal facility with a design capacity of 11,330,917 Megagrams of non-hazardous solid waste (as defined in 6 CCR 1007-2). The landfill began accepting waste on February 3, 1992. Decomposing waste encapsulated within the landfill produces a gas that is primarily composed of methane and carbon dioxide. Emissions of non- methane organic compounds (NMOC), Volatile Organic Compounds (VOC) and Hazardous Air Pollutants (HAP)also result from the decomposition of solid waste placed in the landfill. Fugitive particulate emissions are emitted from the following landfill activities: material transfer to and from storage piles, disturbed areas, wind erosion of storage piles,waste dumping, and vehicle traffic on paved and unpaved roads. The facility is located approximately nine miles east of I-25 on Route 14 where it intersects Weld County Road 25 near Ault. This facility is located in an area classified as attainment for all pollutants except ozone. It is classified as non-attainment for the 8-hr ozone standard and is part of the 8-hr Ozone Control Area as defined in Regulation No. 7, Section II.A.1. There is one affected state within 50 miles of the plant: Wyoming. The following Federal Class I designated areas are within 100 kilometers of the plant: Rocky Mountain National Park and Rawah Wilderness Area. Based on the information provided by the applicant,this facility is categorized as a minor stationary source (Potential to Emit of neither VOC nor NOx> 100 Tons/Year) for NANSR. Any future modification at this facility which is major by itself(Potential to Emit of> 100 TPY of either VOC or NOx)may result in the application of the NANSR review requirements. Based on the information provided by the applicant,this source is categorized as a minor stationary source for PSD as of the issue date of this permit. Any future modification which is major by itself(Potential to Emit of>250 TPY) for any pollutant listed in Regulation No. 3, Part D, Section II.A.44 for which the area is in attainment or attainment/maintenance may result in the application of the PSD review requirements. Emissions (in tons/yr) at the facility are as follows: North Weld Landfill-Fugitive Particulate Matter Pollutant Actual Emissions Potential To Emit Source of Data PM 116.1 152.4 PMio 37.0 50.1 Actual emissions sourced from an APEN received March 14,2016.

Applicable Requirements Accidental Release Program— 112(r) Section 112(r)of the Clean Air Act mandates a new federal focus on the prevention of chemical accidents. Sources subject to these provisions must develop and implement risk management programs that include hazard assessment, a prevention program, and an emergency response program. They must prepare and implement a Risk Management Plan (RMP) as specified in the Rule Based on the information provided by the applicant,this facility is not subject to the provisions of the Accidental Release Prevention Program (Section 112(r) of the Federal Clean Air Act). Compliance Assurance Monitoring(CAM) The following emission points at this facility use a control device to achieve compliance with an emission limitation or standard to which they are subject and have pre-control emissions that exceed or are equivalent to the major source threshold. They are therefore subject to the provisions of the CAM program as set forth in 40 CFR Part 64 as adopted by reference into Colorado Regulation No. 3, Part C, Section XIV: Emission limits are set based on uncontrolled emissions and the installation of the utility flare is voluntary. Therefore this source is not currently subject to CAM. Hazardous Air Pollutants (HAPs) This source is a true minor for HAPs. Greenhouse Gases On July 20,2011,a final rule regarding biogenic CO2 emission was published in the Federal Register. This final action deferred, for a period of three years,the application of the Prevention of Significant Deterioration (PSD)and Title V permitting requirements to carbon dioxide (CO2) emissions from bioenergy and other biogenic stationary sources (biogenic CO2). As it relates to this facility, biogenic CO2 includes all CO2 generated from the biological decomposition of waste in landfills and CO2 emissions from the combustion of biogas collected from the biological decomposition of waste in landfills. The U.S. Court of Appeals for the D.C. Circuit vacated EPA's"Deferral Rule"for biogenic CO2 emissions on July 12, 2013.After July 20, 2014, biogenic CO2 emissions are now considered for PSD permitting purposes. 123/0209 Page 3 of 11 Waste Management Disposal Services of Colorado—North Weld Landfill Operating Permit No. 97OPWE181 Technical Review Document—Second Renewal Operating Permit Standards of Performance for Municipal Solid Waste Landfills That Commenced Construction, Reconstruction, or Modification After July 17, 2014 (40 CFR Part 60 Subpart XXX) The source is considered existing as construction and modification of this facility have occurred prior to July 17, 2014. As this is an existing source it is not subject to NSPS XXX but rather to Emission Guidelines Cf(Eg CO once the EPA approves the state plan for designated facilities as provided in 40 CFR Part 62, Subpart G. Until the EPA approves the state plan for designated facilities the source shall continue to comply with the requirements of NSPS Cc. Under Eg Cf this facility will not have any additional requirements as the current calculated emission rate of NMOC is below the 34 megagram per year threshold. It should be noted that applicable requirements will be reevaluated when new Tier 2 and/or Tier 3 results are submitted. Projecting emissions to inventory year 2021,using the last Tier 2 results of 180 ppmv as hexane and the waste acceptance limit of 1,202,727 Mg per year,the NMOC emission rate approximated by LandGEM version 3.02 will be above the 34 megagram threshold. Once the EPA approves the state implementation plan the source will have 90 days to submit an initial design capacity and NMOC emissions rate report. If the NMOC report indicates exceedance of the 34 megagram threshold,the source will have the option of submitting a gas collection and control system design within one year of submitting the NMOC report, or determining a site-specific methane generation rate constant and recalculating the NMOC emission rate using the site-specific methane generation rate using the Tier 3 procedures, or conducting a surface emission monitoring demonstration using the Tier 4 procedures. If after testing NMOC emission rate is still determined to exceed the threshold the source must submit a gas collection and control system design within one year. Gasoline Dispensing Facilities Contents (40 CFR Part 63 Subpart CCCCCC) The requirements in 40 CFR Part 63 Subpart CCCCCC apply to each Gasoline Dispensing Facility(GDF) at an area source of HAP emissions.A GDF is defined by §63.11132 as any stationary facility which dispenses gasoline into the fuel tank of a motor vehicle. The 560 gallon gasoline storage tank falls under this definition. The storage tank was initially reported as insignificant activity. The storage tank has a monthly throughput of less than 10,000 gallons, therefore the source must comply with the requirements in §63.11116,which include reduction of spills and expeditious cleanup of spill if spill occurs. There are no reportable emissions associated with the storage tank and it is therefore APEN and Construction Permit exempt. However, it cannot be considered an insignificant activity as it is subject to 40 CFR Part 63 Subpart CCCCCC. Regulation Number 7 The source is located in a non-attainment area for the 8-hr ozone standard and is part of the 8- hr Ozone Control Area as defined in Regulation No. 7, Section II.A.1. Regulation Number 7, Section X. Use of Solvents for Degreasing and Cleaning The cold vat degreaser is APEN exempt,however, an emission unit that is subject to specific Regulation No. 7 requirements cannot be considered an insignificant activity. The appropriate applicable requirements are included in the renewal permit;these include transfer and storage of waste/used solvents requirements. It is common to supplement Regulation No. 7 applicable requirements with additional monitoring requirements, but since this unit is APEN exempt additional monitoring requirements are not appropriate. 123/0209 Page 4 of 11 Waste Management Disposal Services of Colorado—North Weld Landfill Operating Permit No. 97OPWE181 Technical Review Document—Second Renewal Operating Permit Regulation Number 7, Section X.E. Control of Industrial Cleaning Solvent Operations Section X.E. applies to all cleaning solvent operations with total combined uncontrolled actual VOC emissions equal to or greater than 3 tons per calendar year. Source indicated that emissions from all solvent cleaning operations on site are less than 3 tons per year,therefore this section does not apply to North Weld Landfill. Regulation Number 7, Section VI. Storage and Transfer of Petroleum Liquid The 560 gallon gasoline storage tank is subject to the requirement of Reg. 7 Section IV.B.3. These requirements are applicable to tanks storing petroleum liquid with a capacity between 40,000 gallons and 550 gallons as rated by the manufacturer. The applicable requirements include use of submerged fill pipe and a vapor control system. Specific design requirements are outlined in Appendix B for both the fill pipe and the vapor control system. Section VI additionally indicates that the filling operation is subject to the requirements of Section XV. Section XV requirements only apply to transfer of petroleum liquids from the delivery tanker to the storage tank and not the distribution of fuel to any fuel tank supplying fuel directly to an engine. Section XV requirements apply to the operator of a vapor collection or vapor control system,which is the tanker truck. These requirement do not apply to the transfer of gasoline from the tank to a motor vehicle fuel tank, which are operations North Weld Landfill performs. Since the vapor control system is essentially the tanker truck(vapor balance system),the following requirements in Reg 7, Section VI.B.3 will not be included in the operating permit as they apply to the tanker truck/vapor control system: • approved vapor balance system (Reg 7, Section VI.B.3.b.(iii)) • vapor balance system specifications (Reg 7, Section VI.B.3.f) • vapor balance system and vapor control system shall meet the requirements of Section XV(Reg 7, Section VI.B.3.g) • control device testing and recordkeeping requirements (Reg 7, Section VI.B.3.h&I) Reciprocating Internal Combustion Engines (40 CFR Part 63 Subpart ZZZZ) Two gasoline-fired engines (Generac Model: 5940, s/n: T57012110062630 and Honda Model: GX 390, s/n: GCANK1348919)were added to the site. The engines are classified as a new RICE located at an area source of HAP emissions which are subject to MACT ZZZZ and comply by meeting the requirements in 40 CFR Part 63 Subpart JJJJ. Standards of Performance for Stationary Spark Ignition Internal Combustion Engines (40 CFR Part 60 Subpart JJJJ) The final rule for 40 CFR Part 60 Subpart JJJJ for spark ignition internal combustion engines was initially published in the Federal Register on January 18, 2008 and subsequently revised on August 30, 2016. There are two gasoline-fired spark ignition engines (Generac Model: 5940, s/n: T57012110062630, 389cc,manufactured: 2012; Honda Model: GX 390, s/n: GCANK1348919,420cc, manufactured: 2016) located at North Weld Landfill. The engines are subject to the requirements of NSPS Subpart JJJJ.Both engines were manufactured after January 1, 2011 and with engine displacement greater than 225cc. Applicable NSPS JJJJ requirements are included in the Permit. The requirements include operating and maintaining 123/0209 Page 5 of 11 Waste Management Disposal Services of Colorado—North Weld Landfill Operating Permit No. 97OPWE181 Technical Review Document—Second Renewal Operating Permit the engines in accordance with manufacturers written instructions and using gasoline that meets the per gallon sulfur limit in 40 CFR 80.195. IV. Modifications Requested by the Source In their modification application submitted on August 1, 2017,the source requested that the permit be revised to incorporate a voluntary Utility Flare. In their application,the source indicated that this modification met the requirements for a minor permit modification and requested that the minor permit modification procedures in Colorado Regulation No. 3,Part C, Section X be used. Colorado Regulation No. 3,Part C, Section X.A identifies those modifications that can be processed under the minor permit modification procedures. Specifically, minor permit modifications"are not otherwise required by the Division to be processed as a significant modification" (Colorado Regulation No. 3,Part C, Section X.A.6). The construction and operation of the Utility Flare will result in an increase in emissions. The requested emission limits associated with this minor modification are as follows:Particulate Matter(PM,PMio, and PM2.5) emissions increased by 2.7 tons per year; Sulfur Dioxide (SO2) emissions increased by 10.3 tons per year;Nitrogen Oxides (NOx) emissions increased by 10.8 tons per year; Carbon Monoxide (CO) emissions increased by 49.5 tons per year. Therefore, since emission increases due to the construction and operation of the Utility Flare did not exceed the significance threshold as outlined in Regulation 3 Part D, Section II.A.44.a or result in a relaxation of recordkeeping and reporting,the Division determines that this modification can be processed as a minor modification. The renewal application received on April 29, 2010 requested the following modifications: • Increase in waste acceptance limit from 450,000 tons per year to 1,323,000 tons per year. o Permit limit directly incorporated from Construction Permit(Issuance 6) issued on March 28, 2019.New waste acceptance limit is 1,202,727 Mg (1,325,405 tons/yr). • Change in Responsible Official and Permit Contact Person. o During the renewal process Waste Management indicated that Steve Derus is no longer the Responsible Official(RO). Bill Hedberg, Senior District Manager, indicated as the current RO. • Permit Limit for landfill gas emissions increase for Carbon Monoxide (CO) from 2 tons per year to 3 tons per year. o Emission limit recalculated using LandGEM with the input parameters detailed in the table below. CO Permit Limit increased to 7.06 tons per year. • Increase in design capacity from 8,145,612 Mg to 10,812,191, Mg. o During the renewal process Waste Management submitted an updated design capacity report on August 1,2017. The design capacity increased from 10,812,191 Mg requested in the renewal application to 11,330,917 Mg. There 123/0209 Page 6 of 11 Waste Management Disposal Services of Colorado—North Weld Landfill Operating Permit No. 97OPWE181 Technical Review Document—Second Renewal Operating Permit were no physical modifications associated with the increase in design capacity. The increase can be primarily attributed to an increase in compaction density and an improved methodology for calculating the design capacity. Since the increase in design capacity did not result from a physical change the landfill is not considered to be modified for the purposes of NSPS XXX. The following values were used to calculate the new landfill gas emission limits: Parameter Values Design Capacity 11,330,917 Mg(Design capacity report received August 1,2017) Methane Generation Rate Constant"k" 0.02 Methane Generation Potential"Lo" 100 NMOC(as hexane) *300 ppmv North Weld Landfill accepts Considerable Quantities of Benzene 11 ppmv PCS as defined in PS Memo# 12-01-"PCS Calculation Procedures,"and therefore the higher concentrations of Toluene 1.59 ppmv benzene and percent NMOC for VOC emissions is used.For Toluene North Weld Landfill conducted site specific testing VOC 85%of NMOC to determine concentration.Toluene concentration will be retested on the same schedule as Tier 2 testing. All other HAPs Default LandGEM Values CO Projected Waste Acceptance Rate 1,202,727 Mg/yr (Permit Limit) Actual Waste Accepted Data from LandGEM report submitted as supporting documentation for APEN received on August 1,2017. *Note:The Division determined that 300 ppmv NMOC as hexane is a more appropriate value to use setting Permit limits for North Weld landfill.300 ppmv NMOC is a conservative estimate considering the most recent Tier 2 result was 180 ppmv. The source's requested modifications were addressed as follows: Page Following Cover Page • Updated RO and Facility Contact Person to Bill Hedberg, Senior District Manager, and Tom Schweitzer, Senior Engineer,respectively. Section I—General Activities and Summary • Updated design capacity to 11,330,917 Mg in Condition 1.1. • Added Utility Flare to Summary of Emission Units Table in Condition 6.1. Section II— Specific Permit Terms • VOC and CO landfill gas emission limits updated based on most recent APEN received on August 1, 2017 and most current LandGEM run. VOC emission limit changed to 39.6 tons per year. CO emission limit changed to 7.1 tons per year. • Added Condition 3 which addresses all applicable requirements associated with the gas collection and control system. 123/0209 Page 7 of 11 Waste Management Disposal Services of Colorado—North Weld Landfill Operating Permit No. 97OPWE181 Technical Review Document—Second Renewal Operating Permit o Emission limits associated with the operation of the utility flare were calculated as follows: Parameter Calculation Various Data Gas Throughput Limit Flare Design Rate Landfill scf min days hr LFG scf scf Gas(LFG) 1,200-x 60-x365 x 24-= 630.72 x 106 1,200— Combusted min hr yr day yr min Emission Limits Assumptions/Source tons lb mmscf 1 ton Assumed CH4 Content: Emissions = EF mmscf CH4 x LFG Combusted x CH4 Content%x yr yr 2000 lbs CH4 Content = 50% PM,PMIo, lb mmscf 1 ton tons EF from AP-42,Chapter PM25 17 mmscf CH4 yr x 630.72 x 0.5 x 2000 lbs _ 2.7 yr 2.4,Table 5 lb x 1012 btu = 68 8 lb lb/mmBtu emission NOx EF 0.068 mmBtu scf CH4 mmscf CH4 factor provided by manufacturer lb btu lb (AP-42,Chapter 13.5, CO EF 0.31 x 1012 = 313.

These requirements indicate that construction of the new flare shall commence within 18 months of approval and shall not discontinue for a period longer than 18 months . Note this Condition was fulfilled after the minor mod was approved (July 5 , 2018) but before the Title V Renewal was issued (DATE), therefore this Condition is not included in the Title V Permit, but was present in the minor mod draft Permit. o Condition 3 . 7 addresses Reg. 3 requirements to notify the Division once operation of the new unit commences . Notice of start up received on January 2, 2019 . Note this Condition was fulfilled after the minor mod was approved (July 5 , 2018) but before the Title V Renewal was issued (DATE), therefore this Condition is not included in the Title V Permit, but was present in the minor mod draft Permit. V. Other Modifications In addition to the source requested modifications, the Division has included changes to make the permit more consistent with recently issued permits, include comments made by EPA on other Operating Permits, as well as correct errors or omissions identified during inspections and/or discrepancies identified during review of this renewal . These changes are as follows : Page Following Cover Page • It should be noted that the monitoring and compliance periods and report and certification due dates are shown as examples . The appropriate monitoring and compliance periods and report and certification due dates will be filled in after permit issuance and will be based on permit issuance date . Note that the source may request to keep the same monitoring and compliance periods and report and certification due dates as were provided in the original permit. However, it should be noted that with this option, depending on the permit issuance date, the first monitoring period and compliance period may be short (i .e . less than 6 months and less than 1 year). • Modified the language concerning postmarked dates for report submittals to reflect the Division ' s current standard language . Section I — General Activities and Summary • Revised the language in Condition 1 .4 include current conditions that are state-only enforceable . • Added 560 gallon gasoline tank, and Safety Kleen degreasing unit to Summary of Emission Units Table in Condition 6 . 1 . • Added two gasoline engines powering generators to Summary of Emission Units Table in Condition 6 . 1 . Section II — S Decific Permit Terms 123/0209 Page 9 of 11 Waste Management Disposal Services of Colorado-North Weld Landfill Operating Permit No. 97OPWE181 Technical Review Document—Second Renewal Operating Permit • Construction Permit 90WE107 (Issuance 6)was issued on March 28, 2019. The following Construction Permit(CP) Conditions require additional discussion for varying reasons as described below: o Condition 5—Emission Limits Included: Construction Permit added facility wide HAP limits of 8 tons per year of any single HAP and 20 tons per year of total HAPs. This change is incorporated into the Title V Permit under Condition 2.1. Not Included: Emission limits associated with the Utility Flare were modified in issuance 6 of the CP,the emissions were modified to match the calculations submitted by the source as part of a modeling report.No new APEN was submitted to modify the flare emission limits originally requested in the minor modification. After further review the Division believes the calculations submitted as part of the modeling report were inaccurate though more conservative. Therefore the emission limits in the Title V Permit will reflect the limits requested in the minor modification application and APEN submitted on August 1, 2017. This does not impact the results of the modeling report since emissions submitted in the report were more conservative. o Condition 8—Process Limit Included: The waste acceptance limit was changed to 1,202,727 Mg per year. This change has no effect on emissions.North Weld reports waste accepted in Mg therefore this change is incorporated into the Title V Permit under Condition 2.4. o Condition 10—Reg 1 Opacity Requirement Not Included: This condition applies to the engines.Note that the opacity requirement for the utility flare is actually the 30%waste gas flare requirement of reg 1 and not the 20%/30%that was listed in the permit—this has been corrected in the operating permit. The opacity requirement was not applied to the 560 gal. gasoline tank and the Safety Kleen degreasing unit as they are VOC sources only and are not expected to produce visible emissions. The opacity requirement was applied to the two gasoline RICE on site. o Conditions 27, 28, &29—Included: The following requirements are imposed as a result of modeled ambient air NO2 (1-hr), PM2.5 (24-hr and annual), PM10 (24-hr), and SO2 (1-hr, 3-hr and 24-hr) impacts that result from the facility operations: • Hour of operation shall be limited to between 0600 and 1800. • The facility shall maintain continuous fencing along the existing fenceline, as well as maintain the slope of the non-fenced areas along the facility perimeter at no less than 20%grading(5:1 slope or 11.3 degrees) which precludes public access in lieu of a fence. • • The facility must limit the number of daily vehicle deliveries to 600 and yearly to 187,200. 123/0209 Page 10 of 11 Waste Management Disposal Services of Colorado—North Weld Landfill Operating Permit No. 97OPWE181 Technical Review Document—Second Renewal Operating Permit o Condition 30—Facility Dust Control Plan The updated dust control plan is incorporated into the Title V Permit without change under Condition 1.2. • Moved Condition addressing requirements for fugitive dust control and limits to Condition 1. • Removed Fugitive Particulate Matter Emissions requirements for opacity.

(WMDSC), Golder Associates Inc. (Golder) is submitting the enclosed renewal application for Title V Operating Permit No. 97OPWE181 for the North Weld Landfill (NWLF), located in Weld County, Colorado. Regulation No. 3, 5 CCR 1001-5, Part C, Section 111.6.6 requires that sources submit an operating permit renewal application at least 12 months, but not more than 18 months, prior to the permit's expiration. Operating Permit No. 97OPWE181 expires on May 1, 2011. Therefore, the enclosed application is being submitted to the Colorado Department of Public Health and Environment(CDPHE) in compliance with the cited regulation. Operations at NWLF are also governed by Construction Permit No. 90WE107. Modification #3 to this construction permit was recently issued by the CDPHE on April 9, 2010. WMDSC is currently preparing a construction permit modification application for submittal to the CDPHE's Construction Permit Unit. An AERMOD modeling package will supplement the construction permit modification application. Requested Operating Permit Revisions For several parameters, the current construction and operating permit limits differ for NWLF. Additionally,WMDSC is requesting permit limit revisions for particulate matter (PM and PM10) and carbon monoxide. Current and requested permit limits are summarized in Table 1. WMDSC requests that discrepancies occurring for permit limits and conditions between the facility's construction and operating permits be resolved by the CDPHE through the Title V operating permit renewal process.

This revision is primarily based on an increase in the waste density resulting from better compaction equipment and techniques since the landfill design capacity was originally determined. Operating Permit Application Summary In general, the enclosed operating permit forms are provided to update or supplement previously submitted information. The attachments are organized into the following sections: general facility information, landfill gas generation, and fugitive particulate matter emissions. Supplementing these sections are updated Air Pollutant Emission Notice (APEN) forms, LandGEM output, and fugitive particulate matter emission estimates.

Emissions are based on waste in place at the end of the prior year. Therefore,2010 values represent emissions for waste in place at the end of 2009. Maximum emissions occur in 2026 based on the estimated closure year is 2025. VOC and HAP emissions are conservative estimates based on default LandGEM model concentration for individual VOC and HAP constituents. Because NMOC=153 ppmv,the total VOC and HAP emissions are likely over reported. Shaded HAP=Reportable emissions for Non-Criteria Reportable APEN Addendum.

LandGEM is considered a screening tool—the better the input data,the better the estimates.Often,there are limitations with the available data regarding waste quantity and composition,variation in design and operating practices over time,and changes occurring over time that impact the emissions potential.Changes to landfill operation,such as operating under wet conditions through leachate recirculation or other liquid additions,will result in generating more gas at a faster rate.Defaults for estimating emissions for this type of operation are being developed to include in LandGEM along with defaults for convential landfills(no leachate or liquid additions)for developing emission inventories and determining CAA applicability.Refer to the Web site identified above for future updates.

The Colorado Department of Public Health and Environment Air Pollution Control Division (Division) first issued the €acility's operating permit on March 1, 2000, which was renewed on May 1,2006.A second Operating Permit Renewal Application was submitted to the Division on April 28, 2010. NWLF currently operates under a permit shield as afforded by the last renewal. This modification qualifies as a minor modification under provisions in Regulation 3, Part C, Section X.A,as the requested modification: • Does not violate any applicable requirement and does not involve significant changes to existing, reporting,or recordkeeping requirements; • Does not request or change a case-by-case determination of an emission limitation or other standard; • Does not seek to establish or change a permit condition or condition for which there is no underlying applicable requirement and for which the source has assumed to avoid an applicable requirement for which the source would otherwise be subject;and • Is not excepted from the definition of permit modification in Regulation 3, Part C, Section l.A.3 and is not otherwise required to be processed as a significant modification, The NWLF has a design capacity greater than 2.5 million megagrams (Mg). The most recent Tier 2 analysis determined the non-methane organic compound emissions from the landfill are currently below the 50 Mg per year threshold as provided in the in New Source Performance Standards Subpart WWW. The NWLF has a collection and control system. This minor permit 1 4 1 Mr. Raz Spencer July 27,2017 Page 2 modification is being submitted to install and operate a voluntary utility flare. The utility flare will combust collected landfill gas. The utility flare is being installed to reduce odors, potential offsite migration,and greenhouse gas emissions. A copy of this submittal has been placed in the site's operating record for this facility. During the course of your review, if you should have any questions or comments regarding this submittal, please do not hesitate to contact me at 970.545.5009.

Once per calendar year, a 1-hour reading shall be performed on the flare in accordance with EPA Method 22, while the flare is operating. If visible emissions are present for more than 6 minutes during the reading a Method 9 opacity observation shall be performed by a certified opacity observer. If any Method 9 observation required under this condition indicates an exceedance of the limit, additional observations shall be performed. Consecutive observations shall be performed until two consecutive observations are in compliance with the standard. All Method 9 readings shall be conducted by an observer with a current and valid Method 9 certification. Results of Method 9 readings and a copy of the certified Method 9 reader's certificate shall be kept onsite and made available to the Colorado Department of Public Health and Environment Air Pollution Control Division (Division) for review upon request. Subject to the provisions of C.R.S. 25-7-123.1 and in the absence of credible evidence to the contrary, exceedance of the limit shall be considered to exist from the time a Method 9 reading is taken that shows an exceedance of the opacity limit until a Method 9 reading is taken that shows that the opacity is less than the opacity limit. • The manufacturer, model number, and serial number of the utility flare shall be provided to the Division within 180 days after commencement of operation. • Emissions of NOx, 5O2, CO, and PM from the utility flare shall not exceed the following limits; 10.88 tons/year, 10.34 tons/year, 49.60 tons/year, and 2.69 tons/year, respectively. Compliance with the annual limits will be determined on a rolling 12-month total. By the end of each month, a new 12-month total will be calculated based on the previous 12 months' data using the following emissions factors, and the amount of methane combusted using the equations below: N0x tons/month = 68.8 lb/MMscf x methane combusted MMscf/month x 1 ton/2000 lbs CO tons/month = 313.7 lb/MMscf x methane combusted MMscf/month x 1 ton/2000 lbs S02 tons/month = Equation 3 of AP-42 Section 2.4.4 Emission factor of 200 ppm will be utilized PM tons/month = 17.0 lb/MMscf x methane combusted MMscf/month x 1 ton/2000 lbs F:IADMININORTH WELD\7I RE VIPERMIT MODIFI MOD SUMMARY.DOIX • Landfill gas combustion in the flare shall not exceed 632.45 MMscf/year. The source shall monitor and record actual gas flow to the flare. Monthly records of gas combustion shall be kept and made available for Division review upon request. Monthly landfill gas combusted shall be used in a 12-month rolling total to monitor compliance with the annual limits. Each month a new 12-month total shall be calculated using the previous 12 months' data. • All calculations requiring the use of methane content shall utilize the most recent data,which will be collected at least every 6 months. • North Weld Landfill is voluntarily installing a landfill gas collection and control system (GCCS).This is a voluntary action and not based on the results of Tier 2 gas sampling and, analysis, which indicated that the generation of non-methane organic compounds has not exceeded the 50 megagrams per year threshold that would require installation and operation of a GCCS.This is a voluntary action and not required by any Federal or State regulation at this time.

Couple of items that need to be addressed: 1)Could you provide the documentation from the manufacturer in regards to the emission factors for NOx and CO. 2)The application did not include a red-lined draft permit with the requested changes. When a'minor mod is approved the draft permit acts as a bridge between the current Permit and the future issuance of the Permit renewal. The approval letter that is sent post review and approval of the modification/draft allows the source to operate in accordance with the draft Permit until the renewal can be issued. It is not uncommon for The Division to write these red-line drafts for the source. In these situations the approval of the modification takes a bit longer but since we are waiting on modeling results regardless it will most likely have very little impact on the timeline. Please let me know if that is the path that you would like to proceed on or if you would prefer to submit a draft for review.

I will get back to you in the next day or two on the first two comments. On the fugitive PM2.5 emissions,we have calculated those emissions as part of the air modeling process. The air modeling report should be submitted by the end of this week. Our plan was to revise the APEN and permit, either the construction permit or the Title V permit or both, after the modeling group approved the modeling report. In addition to adding a limit for PM2.5 emissions,the PM10 emissions limit will also be revised through this process. Please let me know if we should proceed as we planned or if you think we should do something different. If so, perhaps a call or meeting including Michael Harris would be helpful,since he has been involved in the construction permit modification that is associated with the modeling. That sounds confusing,so please let me know if you want to discuss. Thanks again.
