Date: 4/24/23 Priority: ®High ❑ Moderate ❑ Low Modern Geosciences, LLC (Modern) is pleased to provide the attached Padsite Inspection Report documenting the results of our recent inspection and monitoring events at the above-referenced padsite. A general summary of findings is presented below with detailed results provided in the attached report. ■ Field Inspection Results: As part of the field inspection efforts, Modern evaluated the padsite concerning general ordinance or operational requirements set forth by the City. No operational or ordinance compliance issues were noted by Modern during our inspection efforts other than noted below: • Bare pipe/corrosion noted on Wells A through L. According to the Operator representative, all corrosion observations were addressed as of June 1, 2023, thus the corrosion observations are no longer considered Action Items. Future verification suggested. ■ Near-Equipment Inspection Results: Our inspection efforts at this padsite included near- equipment monitoring using optical gas imaging(OGI)to identify leaks of methane and/or volatile organic compounds (VOCs) and radiation meters to identify equipment exhibiting naturally- occurring radioactive material (NORM)above applicable regulatory criteria. The accumulation of scale within equipment can cause elevated NORM levels requiring proper signage and equipment management. A summary of near-equipment findings is presented below with further detail in the attached report.

If the concerns were not addressed, these are included in the Action Items listed below. If items were addressed, this will be documented in the report. ■ Fenceline Inspection Results: Our inspection efforts for this padsite included an evaluation of air quality at representative upwind and downwind points at the padsite boundary. Our approach utilized a variety of equipment to screen for potential impacts that could affect air quality off of the padsite or suggest additional monitoring may be warranted. Please refer to the report for additional detail on our findings. Fenceline inspection did not identify air quality concerns above program screening goals. ■ Action Items: If items are identified during our inspection that remain unresolved or require future confirmation, these will be listed as individual action items for the operator until the City has confirmed further action is not required. There are no outstanding Action Items as of the date of this report. ■ Inspection Data Trends (Leak and NORM Rate): Modern performed a review of inspection data across five(5) North Texas municipalities that use similar inspection methods and data acquisition to develop benchmarks concerning padsite and/or operator performance. This included inspection of over 2,600 wells and 8,000 pieces of supporting equipment. Implementation of these inspection programs resulted in an estimated 56%decrease in leaks. Using these data sets, Modern prepared the following benchmarks for general reference purposes concerning the Leak Rate (number of leaks divided by the number of wells) and NORM Rate (amount of equipment with NORM >50 µR/hr divided by number of wells). While each padsite is unique and will have operational and equipment differences, when normalized to a "per well" basis for tracking it provides a useful benchmark. Performance Leak Rate NORM Rate Good <0.5 <0.4 Moderate >_0.5 to<1.5 >_0.4 to<1.2 Poor >1.5 >1.2 The Leak Rate and NORM Rate for this padsite over time are presented below: 5100 THOMPSON TERRACE,COLLEYVILLE,TEXAS 76034 1 F 682.223.1593 1 P 682.223.1322 www.MODERNGEOSCIENCES.com <S1 MODERN GEOSCIENCES TRUSTED ENVIRONMENTAL ADVISORS Leak and NORM Rate 2.00 a, 1.50 0 1.00 z 0.50 _ ai J 0.00 - -1 Leak Rate NORM Rate ■ Next Inspection Event: The City of Denton completes periodic inspections at all padsites throughout the year. In addition to this, the City has asked Modern to perform supplemental inspections with high-resolution equipment based on proximity to sensitive property uses. Based on the current prioritization, this padsite is scheduled to be inspected again by Modern in the second half of 2023. CLOSING We appreciate the opportunity to provide our services to you.

Within their response to the EPA, the INGAA noted the following, "the INGAA recommends a leak definition concentration of 10,000 ppm.This is consistent with the range of thresholds in current regulations,also consistent with the OGI performance objectives in §60.5397a(c)(7)(i)(B), and consistent with the Subpart W leak definition." This methane concentration also represents 20% of the Lower Explosive Limit and is consistent with 40 CFR §60.18(g)(6) (i) ["any emissions imaged by the optical gas instrument"].A lower leak definition and additional inspection and reporting may be required at facilities subject to 40 CFR§60 Subpart OOOOa. Documented continuous low-bleed components (<6 scf/hr) and intermittent emissions from properly functioning pneumatic devices are not considered leaks for the purposes of this inspection. The term"leak"is used within this inspection effort to define potential fugitive emissions that appear to be continuous in nature and suggestive equipment and/or components are not functioning properly. 2-The Texas Railroad Commission (RRC) regulates NORM under 16 TAC §4 (Environmental Protection, Subchapter F, Oil and Gas NORM). Subchapter F establishes the requirements for oil and gas NORM waste disposal for the purpose of protecting public health and the environment.NORM-contaminated equipment is defined in Subchapter F as"equipment that,at any accessible point,exhibits a minimum radiation exposure level greater than 50 µR/hr including background radiation level." When identified,the equipment suspected of being NORM-containing will be communicated to the City and operator(s)to allow further inspection and where appropriate compliance with RRC signage and management requirements. 3-Represent half of the American Conference of Governmental Industrial Hygienists(ACGIH)8-hour threshold limit value(TLV)of 1,000 ppmv (0.1%by volume)set for potential cardiac sensitization and central nervous system depression. 4-Consistent fenceline concentrations of 0.1 ppmv could indicate a potential off-site air quality exceedance of applicable TCEQAir Monitoring Comparison Values (AMCVs) or Effect Screening Levels (ESLs). Further sampling will be needed to confirm the individual compounds present and direct regulatory comparison. 5-Indicative of possible 30 TAC§112.31(30-min avg.)exceedance of 0.08 ppmv. Further sampling will be needed to confirm the 30-minute average and allow direct regulatory comparison. 6-EPA average background criteria established under Document No.402-R-08-005;April 2008. Reported background ranged from 10 µR/hr to 85 µR/hr. Elevated fenceline observations may require further screening to confirm attenuated levels near sensitive receptors. 7-National Ambient Air Quality Standard (NAAQS) for Particulate Matter (PM) PM2.5. Further monitoring will be needed to confirm if a continuous average(24-hr,3yr)exceedance is indicated. Elevated PMz.5 can also be indicative of elevated semi-volatile organic compounds or other emission products may be present. Individual COC monitoring required for comparison with AMCVs or ESLs. 8-NAAQS for PMlo. Further monitoring will be needed to confirm if a continuous average(24-hr,3yr)exceedance is indicated. 9-A-weighted L,q criteria consistent with the Federal Interagency Committee on Urban Noise (FICUN) "Guidelines for Considering Noise in Land-Use Planning and Control"maximum level for"acceptable"uses. Other permit-specific criteria may be applicable. Modern's sound sampling event represents only a short event at the boundary nearest an enclosed structure. Further attenuation may be present if the sampling point is adjusted. Completed using a Class 1 microphone with 3-octave bands allowing further detail if needed. Further monitoring will be needed to confirm if average sound conditions exceed applicable criteria.

Based on this evaluation, ordinance thresholds were not exceeded. A depiction of pure tone comparisons is included in the attached graph(s). Notes: 1- Represents the maximum discrete sampling result recorded by Modern across fenceline screening alignment. 2- Represents the approximately 10-minute average result recorded by Modern. Sample point selected by field professional as a conservative representation of fenceline conditions at the time of sampling. 3- Represents the approximately 1 to 5-minute average result recorded by Modern. Sample point selected by field professional as a conservative representation of fenceline conditions at the time of sampling. When available,site-specific ambient levels are presented(default is 65 dBA). 4- Perimeter monitoring occurred at the padsite fenceline closest to an apparent occupied structure. If an exceedance of our screening criteria is noted at this point,a secondary(alternate)monitoring event is conducted approximately 100 feet from perimeter toward the nearest occupied structure to allow an understanding of site-specific attenuation. Further monitoring may be needed to evaluate tonal compositions and longer time-weighted averages. General Inspection Program Notes: 1- Modern confirmed operation of all field equipment in accordance with manufacture specifications and Modern's standard operating procedures prior to field inspection efforts. This included the use of zero and prepared calibration samples. 2- Modern's services were performed in a manner consistent with a level of care and skill ordinarily exercised by other members of our profession practicing in the same locality,under similar conditions and at the time the services were performed. The scope of services performed was in accordance with the scope of work agreed with by our client,as set forth in our proposal and related authorization agreement(s). 3- Laws,regulations and professional standards applicable to Modern's services are continually evolving. Techniques are,by necessity,often new and relatively untried. Different professionals may reasonably adopt different approaches to similar problems. As such, our services are intended to provide our client with a source of professional advice, opinions and recommendations based on a limited number of field observations and tests,collected and performed in accordance with the generally accepted practice that exists at the time,and may depend on, and be qualified by, information gathered previously by others and provided to Modern by our Client. Modern does not warrant the work of third parties supplying information used in the report. 4- The monitoring results collected as part of these services represent field conditions at the time of inspection or monitoring only. Samples or monitoring data collected at other times may reveal different results that are representative of site conditions during other periods of time. The use of monitoring efforts is not intended to replace laboratory methodology,but rather provide data indicative of when additional efforts may be warranted. Modern's air sampling is consistent with current regulatory guidance and/or manufacturer specification. For a higher level of certainty,our monitoring methods can be expanded over longer periods of time and/or supplemented by use of a state-accredited laboratory when evaluation of specific COCs is desired or further verification is needed.
