The physical inspection occurred over two days. The following subsections describe the inspection activities completed by the EPA inspection team. The System representatives provided documents in response to a document request included in the EPA Region 6 inspection notification email. The information in this report is based on document review, conversations with System representatives, and observations made during this inspection. KWE/E'KE&ZE The EPA inspection team arrived at the System, located at 1104 N Waterplant Rd., Duncan, OK 73533, at 0830 CDT on July 28, 2025, for the inspection. The EPA inspection team was accompanied by Isaac Sparks, Kimberly Wirtz, and Thomas Nguyen from DEQ; refer to Appendix B for the opening conference sign-in sheet. Daniel Kim and Kevin Sarmiento presented their credentials to Karl Holtz and informed them that this was an EPA Region 6 inspection to determine compliance with the SDWA and O.A.C. requirements. The EPA inspection team also informed the System representatives that they would be conducting a cybersecurity evaluation alongside the SDWA Section 1433 review of the System's Risk and Resilience Assessment (RRA) and Emergency Response Plan (ERP). The opening conference included a discussion of system details, surface water sources and treatment, and Supervisory Control and Data Acquisition (SCADA). Additional conversations throughout the inspection process included technical, managerial, and financial capacity of the System, monitoring and reporting requirements, cross-connection control, emergency response plan and management, staffing, plans in place for lead and copper rule (LCR), disinfection byproduct rule (DBPR), revised total coliform rule (RTCR), treatment techniques, and others discussed in more detail in the remainder of Section II. DE'DEdEKWZd/KE The System is owned and operated by the City of Duncan. Two of the three source water lakes, Lake Humphreys and Lake Fuqua, are owned and managed by the City of Duncan with the third source, Lake Waurika, owned and managed by the U.S. Army Corp. of Engineers. Nine licensed operators cover three shifts at the water treatment facility to ensure 24 hours of coverage per day. The facility is classified by DEQ as a Class A facility due to demand and treatment complexity. Routine checks of the distribution system assets, including monitoring chlorine residual and phosphate levels, are completed by distribution staff Monday through Thursday and by treatment operators Friday through Sunday. Chlorine residuals are monitored and recorded at water storage facilities twice per day as required. These residuals are monitored manually as there is no chlorine residual monitoring instrumentation at any of the water storage tanks. The breakdown of operator certification levels are as follows: x Two operators hold a Class A Water Operator License. x Three operators hold a Class B Water Operator License. x One operator holds a Class C Water Operator License. x Three operators hold a Class D Water Operator License. x One operator in training is testing for the Class D Water Operator License. 4 WhZWt^/K< /Z ZZ^ZKZZZ dZKZdKddZZZZZZ ZZ:ZZ^Z YdZK^ZZZ: ZdKdd:ZdKdd ZZZZZZ ZZYZdK ddZZZZ/ZZZZ^ ZZdKZ d^ZZZZZ Z^ZZ^Z ZZKYZZ ZZZdKZ ,ZWZZZZ^ /ZW^Z /ZWdZK^ZZdKdd : ZWZZZ ZZZZZZ^ ZZZZZ&ZWZ ZZZZ ZZZZZZZ ZZZZ^ ZZ d^ZZZZZZZZZZZ ZZZZZZZZZ^ ZZZW/Z ZZZZZZZZZ^ ZZZZZZ ZE&WZZ& ^ZZ&Z ZZZZ ZZZZ tW/WWZ/WWZ,ZZ ZWZZZZZ^ ZZ d^ZZZ^ &WZW^d^Z&Z ZZ^&Z ZZZZZZ^ WhZWt^/K< /Z d^Z^ ZZZZZ ^ZZZ dZZZZ ZZ^ ^YZ^ZtWZ^ ZZZZ d^ZZZZZ ZZZZZ^ ZZZZsZZZKZ ZZZZZZZZZZ ZZZZZZZdZK ^ZZZZZZZW :d^WZZZZZ ZZZ,ZZWZ ^ZZZZ ZZZZZ^ KhDEdZs/t dWZZZ^ZZZZZ Z&ZZZZZZWZZ Z^WZZZZ ZZZZZZZZdZ ZZZZdZ^^WZZZWZ>ZZ >ZZZ>ZZ/Z>Z/WZZZW&^ hZDZZZhDZZ ZZZZZZZd^ ZZZZZZ d^ZZZZZWZ^ ZZZZZ ZZZ,Z ^&WZW WZZ^ WZWZ d^>Z^WZZYZ ^ZZ d^>^>/Z>^>/^ ZZZZZ^Z^ ZZZZ>^>/Z ZZZZ ZZZZ ZZ WhZWt^/K< /Z dWZ^^ZZZ ZZWdWZZ^ &/>/dzt><d,ZKh', dWZZZZ tdW>,Z ZZZ dZZZZ dZZZZZZZZWZ^ ZZZZZZZ ^Z///ZZ tdW dtdWZ>t>,>&> tZh^ZZZZZ ZZZZtDZ>, >&ZZWZ >,ZZZZZZ>t ZZZdtdWZZZZZZZ ZZEZW^ZW ZZZ,ZZd^Z ZZZZdZZZZ& ZEZ^ZWZZZZZD'd ^ZZZZW,Z^ ZZdZD'YZZZZZ d d^ZZZZZZZZZZZ,Z ZZZZD'& ZZZ dWZZZZtdWEZ^Z dEZZZZWZZ ZZZZZZ tdW^d dZZZ Z dWZZZZZZ x dZZZZZ WZZ x ZZZZ ZWZZ x dZZZZZ x WZWZZ WhZWt^/K< /Z x d^ZZZZZZ ZZ tdW^Z&D ,ZZZ^ZW Z dWZZZZZZ x dZZZZZZZZ Z,ZZZWZZ x ZZZZZ ZZ,ZZZWZZ x d,ZWZZ tdWWZZ,Z ^^ZZZ WZZWZZZZZdKZZ ZZZZZ ZZWZZ tdW^ZW d^ZWZZZZZ ZZZZZZZ Z^ZZ ZZZ tdW^ZW& d^ZW^ZZ ZZZZZ ZEdhZdZZZZ ^ZEdh/ EdhZZZZZZZ dZZZZZZZZ ZZWZZdWZZZZZ ZZZWZZ^ ZZZZZZ ZZZ dWZZZZ^ ZZZZ Z^ZZ ZZ WhZWt^/K< /Z dWZZZZZZWZZ WZZ tdWZWZ d^ZZZZZZZ ZZZKZ ZZZZZZZ^ ZZZZZ ZZZZZZZZZ dWZ^Z ZZZZZZWZZ tdW^ZW&W'D' d^ZW&W'ZZZZ^ZW& ZD'd^ZWD'^Z ZZD' dWZZZZZZ x ^ZZZZD' WZZ x KZZZZZZD' WZZWZZ x ZZZZZZ ZZZ^ZZWZZ WZZ x ZZZ^Z&Z WZZWZZ tdWZZW&W dZZZZZZZZZZ D'dWZZZ ZZZZWZZ dZZZZZ ZZdWZZZZZZ ZZWZZ tdWZ&ZZZ dWZZZ&ZZZZ ZZZZZ^ ZZZZKZ ZZZZZ^ZZZZ ZZZZZZdWZ Z'^d,ZZZZZ WhZWt^/K< /Z WZZ^ZZZ ZZ tdWZ^ZZZZ dZ^ZZZZZZZ&ZZZZ ZZZ dWZZZZZZ x ZZZZZZZZ ZWZZ^ZZZZ WZZ x dZZZZZZZWZZZZ ZZE^&WZZZZ ZZZZWZZWZZ ZWZZ^ ZZZZZZ ZZZZZ x ^ZZZ ZZZZZZZWZZ x KZZZZWZZWZZ ^ x &ZZZZZZWZZ x EZZZZZZZ WZZ x dZZZZZZZZWZZ tdWD'Z dD'ZZEZ^Z WdZZZ Z dWZZZZZZ x ZZWZZ WZZ^ Z x ZZZZ WZZ x ZZZZZZZZZZ ZZWZZWZZ x WZZZZZ ZZZZKZ ZZZZWZZWZZ WhZWt^/K< /Z tdWWZZ^Z&DZZ/Z d^,ZZZZZZ ZZdZZ ZZZ dWZZZZZZ x &ZZZZ x dZZZZZZZZZZZZZ WZZ^Z ZdZZZZZZ x ZZZZZZZZ ZZZZZZWZZWZZ WZZWZZ^ZZZ ZZZZZ ZZZ x EZZZZZ ZZZZZZZZWZZ tdW,^Z d^ZZZZZZZZ, ZZZ^ZZ Z,ZWZZZ Z,ZZZ ^ZZZ ZZWZZ dWZZZZZZZZ ZZZZ ZZZWZZ dWZZZZZZZ WZZ tdWZ'^Z&ZZZ d^ZZZZZ ZZZZ^ZZ ZZZZ tZZZ^ ZZZ dWZZZZZZZZ ZZZZZZZZWZZ WhZWt^/K< /Z dZZZZZZZZZZ ZZdWZZZZZZ ZZZWZZ tdWWZ^Z&ZZZ Z/ZZh&Z,sZZZZZZ ZZZdZZZEZZZ^ZWZ ZZ/ZdWZZZZ ZZ/ZZZZWZZ d^ZZZdW ZZZZZ^ Z dWZZZZZZZ WZZ tdW^ ^ZZZ^ Zd^Z ^ZZZZZZZZ ZZZZZZZZEdhZ dWZZZZZZZ ZZ ZZZWd^ ZZZZZWdd^ ZZZ^ tdW>ZZ ZZZZZ ^ZZZZZZ ZZZdWZZZ,ZZ ZZZZ >,/ d>,ZZ ZZZZ>,dWZZZZZ ZZ^ ZZZZZZZZZdZZ ZZZZZZZZh^'ZZ ^ WhZWt^/K< /Z ,WZ^ZW^Z&ZZZ d,WZZZZZ ZZtdWEZZZZW Z^ZZ>, >&ZZZZ>td WZZZZWWZZ d^ZZZZZZZ> ,>&ZZZ>&ZZ Z>,WZZ>,WZ ZdWZZZZZ ZZZZZZWZZ^ ZZZZ ZdWZZZ ZZZZWZZ ZZdZ ZWZ^ZD'ZZ D'ZZdZdWZZZ ZZZZZZZ ZZWZZWZZ D'ZZdZWZZZZZZ x ZZZ ,Z^ZZZZZ ZZWZZ x dZZZZWZZ x ZZZZZZ ZZZWZZ x Z^ZZ Z x >ZZZZ ZZZZZWZZ WZ dWZZZZZZZZ Z dWZZZZZZ x ZZZZZZ WZZ x ZZZZZZZZ WZZZZZZ ZZZZZZZ d WhZWt^/K< /Z dZD'^Zd D'EZdD'EZd ZZZZZ dWZZZZZZ x sZZZZZZZZ WZZWZZWZZ x ZZZ ZZZWZZWZZWZZ x ZZZZZZ^ZdWZZ WZZ x WZEdWZZEtd WZZ EZ/dZt dWZ^ZZEZ/dZ tZZZZZ ZZWZZ^ ZZZZdZ ZZZZZZZZ EZ/dZ dEZ/dZD' dWZZZZZZ x sZZZWZZ x WZZZZZZWZZ x dZZZZZZZ WZZ EZ^ZdZ dEZ^ZdZD'dWZZ ZZZZWZZ EZ,WZ dEZ,WZZZZsZZZ KZZdWZ ZZZZZZZ dZZZ ,ZWZZZZZ WZZ >K^/E'KE&ZE WhZWt^/K< /Z dWZ ZZ^Z Z : tdW ZZZ d W Z ZZ ZZZ ZdWZ Z ^ ZZ ZZZ W ZZ Z Z Z Z WZZZZ ZZdZZZ ZZ ZZ ZZKZ ^Z /// KZZ ^ d Z Z Z Z ZZ Z ^Z ///ZK& KEZE ^t ^Z SDWA Section 1433(a)(1)(A) requires a CWS serving more than 3,300 persons to conduct a Risk and Resilience Assessment ("RRA") of its system, including an assessment of: i. the risk to the system from malevolent acts and natural hazards; ii. the resilience of the pipes and constructed conveyances, physical barriers, source water, water collection and intake, pretreatment, treatment, storage and distribution facilities, electronic, computer, or other automated systems (including the security of such systems) which are utilized by the system; iii. the monitoring practices of the system; iv. the financial infrastructure of the system; v. the use, storage, or handling of various chemicals by the system; and vi.
