Are there appropriately certified Operators in Charge (ORCs) for the facility? Yes No N/A ORC: Joedavid Hall Certificate #: Backup ORC: Certificate #: 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: A 0.01 MGD package plant consisting of an aeration basin, diffusers, rectangular clarifier, sludge holding tank, chlorinator and dechlor. Proposed flow: Current permitted flow: 0.02 MGD (needs to be updated) 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.) Please note there are discrepancies based on the originally issued AtoC and the permitted flow over the years. Our records indicate the facility was originally issued an AtoC for a 0.01 MGD facility which would later be phased to 0.02 MGD as the development grew (addition of a second treatment train). No records in our database show an additional or revised AtoC was ever issued. During my inspection, the facility did not appear adequately sized visually to be permitted for 0.02 MGD. The permittee was asked to verify or provide documentation of the true hydraulic capacity. The ORC conducted a volume test and determined the aeration basin was sized for approximately 0.01 MG. Environmental Inc. Contract firm indicated they would submit an email regarding the volume test. 3. Are the site conditions (e.g., soils, topography, depth to water table, etc) maintained appropriately and adequately assimilating the waste? Yes or No - NA 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 comments above about recorded permitted flow. 5. Is the residuals management plan adequate? Yes or No If no, please explain: 6. Are the existing application rates (e.g., hydraulic, nutrient) still acceptable? Yes or No NA 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: DocuSign Envelope ID: 05DCE873-055F-4983-B801-93E1E066BEF2 FORM: WQROSSR 04-14 Page 3 of 5 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: See comments above. 10. Were monitoring wells properly constructed and located? Yes No N/A If no, please explain: 11. Are the monitoring well coordinates correct in BIMS? Yes No N/A If no, please complete the following (expand table if necessary): Monitoring Well Latitude Longitude ○ ′ ″ - ○ ′ ″ ○ ′ ″ - ○ ′ ″ ○ ′ ″ - ○ ′ ″ ○ ′ ″ - ○ ′ ″ ○ ′ ″ - ○ ′ ″ 12. 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: One monitoring violation in 2017. No consistent compliance issues noted 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. Has the RO been working with the Permittee? Is a solution underway or in place? Have all compliance dates/conditions in the existing permit been satisfied? Yes No N/A If no, please explain: 15. Are there any issues related to compliance/enforcement that should be resolved before issuing this permit? Yes No N/A If yes, please explain: 16. Possible toxic impacts to surface waters: Chlorine disinfection; however, dechlorinated before discharged. 17. Pretreatment Program (POTWs only): N/A DocuSign Envelope ID: 05DCE873-055F-4983-B801-93E1E066BEF2 FORM: WQROSSR 04-14 Page 4 of 5 IV. REGIONAL OFFICE RECOMMENDATIONS 1.

ADDITIONAL REGIONAL STAFF REVIEW ITEMS Environmental Inc. should be sending in an email stating the results of the volume test conducted by the ORC. No additional documentation on file in the ARO and/or central office indicate modifications were made to permit or increase the originally issued AtoC from 0.01 to 0.02 MGD. Please note, the ARO does not currently have any concern with the facility, as of right now, of exceeding the hydraulic capacity of the currently installed treatment train (0.01 MGD). The annual average daily flow from the past 12 months was approximately 800 gallons. DocuSign Envelope ID: 05DCE873-055F-4983-B801-93E1E066BEF2
