Are the new treatment facilities adequate for the type of waste and disposal system? Yes or No If no, explain: DocuSign Envelope ID: A5E497D6-2FDE-4FF8-8254-067C97C01F39 FORM: WQROSSR 04-14 Page 2 of 6 3. Are site conditions (soils, depth to water table, etc) consistent with the submitted reports? Yes No N/A If no, please explain: 4. Do the plans and site map represent the actual site (property lines, wells, etc.)? Yes No N/A If no, please explain: 5. Is the proposed residuals management plan adequate? Yes No N/A If no, please explain: 6. Are the proposed application rates (e.g., hydraulic, nutrient) acceptable? Yes No N/A If no, please explain: 7. Are there any setback conflicts for proposed treatment, storage and disposal sites? Yes or No If yes, attach a map showing conflict areas. 8. Is the proposed or existing groundwater monitoring program adequate? Yes No N/A If no, explain and recommend any changes to the groundwater monitoring program: 9. For residuals, will seasonal or other restrictions be required? Yes No N/A If yes, attach list of sites with restrictions (Certification B) Describe the residuals handling and utilization scheme: 10. Possible toxic impacts to surface waters: 11. Pretreatment Program (POTWs only): III. EXISTING FACILITIES: MODIFICATION AND RENEWAL APPLICATIONS 1. Are there appropriately certified Operators in Charge (ORCs) for the facility? Yes No N/A ORC: Shannon James Certificate #:1002526 Backup ORC: Juanita James Certificate #:24074 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: Back-up ORC, Juanita James, reports the 1000-gallon aerobic digester does not have adequate capacity to waste solids as often as needed. This is currently being supplemented by pumper truck visits. Description of existing facilities: Aerated EQ Basin, followed by aeration basin equipped with diffused air set on timers. Hopper style clarifier with airlift pump. 1000-gallon aerobic digester. Chlorination tubes/chlorine contact chamber, Effluent weir box, ultrasonic flow meter with chart recorder. Effluent pump station, dechlorination tubes and wet well. Proposed flow: NA Current permitted flow: 5860 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.) Current permit and permit application listed the components of the previous sand filter system. The entire WWTP was upgraded in 2014-2015 to an activated sludge facility. The permit was never updated to reflect these changes (treatment components, effluent parameters and monitoring frequency). 3. Are the site conditions (e.g., soils, topography, depth to water table, etc) maintained appropriately and adequately assimilating the waste? Yes or No N/A 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: Facility description should be updated to reflect changes. 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 N/A If no, please explain: DocuSign Envelope ID: A5E497D6-2FDE-4FF8-8254-067C97C01F39 FORM: WQROSSR 04-14 Page 3 of 6 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: Permit was never updated to reflect the facility upgrade. See above for a list of currently installed treatment components. 10. Were monitoring wells properly constructed and located? Yes No N/A If no, please explain: DocuSign Envelope ID: A5E497D6-2FDE-4FF8-8254-067C97C01F39 FORM: WQROSSR 04-14 Page 4 of 6 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: There have been four limit violations since the facility was upgraded in 2015. One TSS, two BOD and one Flow limit violation. 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.): There was one NOV for a BOD limit violation in the most recent 12-month monitoring period. 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? Ms. James reports they have not experienced issues with flow since installing the new WWTP. Flow readings need to be verified. According to the ORC’s logbook the flow meter is reading inaccurately. The ORC is reporting grab flows on the DMR. Flow meter, if going to be used, needs to be replaced or calibrated more frequently. See inspection report for additional details. 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: 17.
