Are there appropriately certified Operators in Charge (ORCs) for the facility? Yes No N/A ORC: Bob Barr Certificate #: SI / 24262 Backup ORC: Kenneth Rummel Certificate #:SI / 1010634 2. Are the design, maintenance and operation of the treatment facilities adequate for the type of waste and disposal system? Yes or No If no, please explain: Description of existing facilities: Wastewater from the site is treated utilizing EZ-treat technology before being applied to drip fields (forest) nearby. An unlined 606,496-gallon unlined wet-weather storage pond is available. A flow reduction was granted in September 2021 and generally the site processes much less wastewater than they are permitted to. The facility is mostly seasonal, with minimal flows December – April. The site anticipates higher flows and additional buildouts in the coming years. Proposed flow: 40,000 GPD Current permitted flow: 40,000 GPD Explain anything observed during the site visit that needs to be addressed by the permit, or that may be important for the permit writer to know (i.e., equipment condition, function, maintenance, a change in facility ownership, etc The ARO and permitting team have been in communication with Mark Brooks (engineer for the WWTS), representatives from CSC Construction Management, RPB Systems (ORC) and the site owners (Northgate Holdings) regarding temporary and long-term changes to the drip irrigation area. Drip subzones 9-12 are temporarily offline to provide access to an old logging road that transects the fields. The area was surveyed in February 2023 and engineering calculations show that the resulting reduced flow should be adequate for the expected wastewater demands during construction (March – May 2023). The plan is to proceed with a permit renewal, keeping the permit as-is for now. Mark Brooks will submit a permit modification application in late 2023 to reflect the long-term removal of the damaged parts of sub-zones 9-12 and potentially the addition of a new field to meet wastewater flow demands as the site continues to grow and utilize its full capacity. 3. Are the site conditions (e.g., soils, topography, depth to water table, etc) maintained appropriately and adequately assimilating the waste? Yes or No If no, please explain: 4. Has the site changed in any way that may affect the permit (e.g., drainage added, new wells inside the compliance boundary, new development, etc.)? Yes or No If yes, please explain: See summary above. 5. Is the residuals management plan adequate? Yes or No If no, please explain: DocuSign Envelope ID: 737D7FB0-A801-45D8-A0D5-F50C455A8FAB FORM: WQROSSR 04-14 Page 3 of 7 6. Are the existing application rates (e.g., hydraulic, nutrient) still acceptable? Yes or No If no, please explain: 7. Is the existing groundwater monitoring program adequate? Yes No N/A If no, explain and recommend any changes to the groundwater monitoring program: 8. Are there any setback conflicts for existing treatment, storage and disposal sites? Yes or No If yes, attach a map showing conflict areas. 9. Is the description of the facilities as written in the existing permit correct? Yes or No If no, please explain: 10. Were monitoring wells properly constructed and located? Yes No N/A If no, please explain: DocuSign Envelope ID: 737D7FB0-A801-45D8-A0D5-F50C455A8FAB FORM: WQROSSR 04-14 Page 4 of 7 11.

Has a review of all self-monitoring data been conducted (e.g., DMR, NDMR, NDAR, GW)? Yes or No Please summarize any findings resulting from this review: Groundwater: Results (last collected July 2022) were all below compliance standards. NDMR/NDARs: Average flow is about 141 GPD, with peak flows in July and August (~5,000 GPD). There were no exceedances of effluent compliance standards in 2022. Provide input to help the permit writer evaluate any requests for reduced monitoring, if applicable. 13. Are there any permit changes needed in order to address ongoing BIMS violations? Yes or No If yes, please explain: 14. Check all that apply: No compliance issues Current enforcement action(s) Currently under JOC Notice(s) of violation Currently under SOC Currently under moratorium Please explain and attach any documents that may help clarify answer/comments (i.e., NOV, NOD, etc.) If the facility has had compliance problems during the permit cycle, please explain the status.

Schedules Within 90 days of permit issuance the Permittee shall submit two original copies of a site map with a scale no greater than 1- inch equals 100 feet; however, special provisions may be granted upon prior approval for large properties. At a minimum, the map shall include the following information: a. The location and identity of each monitoring well. b. The location of major components of the waste disposal system. c. The location of property boundaries within 500 feet of the disposal areas. d. The latitude and longitude of the established horizontal control monument. e. The elevation of the top of the well casing ( i.e., measuring point) relative to a common datum. f. The depth of water below the measuring point at the time the measuring point is established. g.

ADDITIONAL REGIONAL STAFF REVIEW ITEMS As mentioned above, in section III.2, the ARO anticipates either a major or minor modification submittal in late 2023, reflecting the removal of subzones 9-12 and potentially the addition of a new drip field on site. Additional options are being explored as well. A site map needs to be submitted and added to the permit, as it was never provided to the ARO after the installation of new groundwater monitoring wells.
