NCO047759 I11 12I 21/12/16 117 18 i c i Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) A routine compliance inspection of the Pruitt Health at Sea Level Wastewater Treatment Plant (WWTP), was performed on December 16, 2021. The purpose of the inspection was to verify that the facility is operating in compliance with the conditions and limitations specified within Permit NC0047759. Patricia Davis, contract operator in responsible charge (ORC), was present during the inspection. According to the current permit which was issued 7/7/2017, became effective 8/1/2017 and expires 7/31/2022, the wastewater treatment and closed loop recycle facility consists of: - An influent pump station; - A manual bar screen; - An equalization basin with aerated flow; - A flow splitter box; - Dual package plants (for a total flow of 0.014 MGD) extended aeration units with: o Extended air -activated sludge basins; o Clarifiers; o Aerobic digesters; - Dual tertiary filters; - Chlorine contact basin with liquid chlorine equipment; - Liquid sodium bisulfite dechlorination equipment; - A flow measuring device; - A clearwell; and, - A mudwell. A review of monitoring records since the last inspection performed on 2/1/2017, indicate that the system has had violations of daily exceedances of BOD5 or enterococci on 7/2/2018, 9/10/2018, 6/10/2019, 11/12/2019, 3/16/2020, 7/6/2020, 7/20/2020 and 7/12/2021. It should be noted that with the exception of the samples obtained in 7/2020, all other subsequent sampling events resulted in results below daily maximums and below monthly average limits. Daily exceedances were attributed to required chlorine and bisulfite adjustments as well as possible temperature and other demand changes within the wastewater. The following items are recommended to be corrected or addressed for the facility (with some of these items having been mentioned within the 2/1/2017 inspection report): 1. A bar screen should be installed as mentioned within the permit. These structures are highly recommended to be installed in order to keep solids out of the equalization basins. If the system does not feel as though the structure is warranted, a request should be made to eliminate this structure from the permit. A hanging basket -type was previously indicated as being purchased; however, a review of our files does not indicate that our office was ever contacted to inform us that the structure was installed — despite our prior request. 2. Landscaping debris has been stockpiled within the access path to the discharge outfall. The path to the outfall needs to be cleared and maintained in order to check the line for breaks and maintain the line, as needed, as well as to ensure that the outfall does not contain floating solids or foam (per conditions of the permit). 3. Corrosion of the metal tank which encompasses the equalization/filter/mudwell/clearwell was observed. Tank refurbishing or a plan maintain this structure is needed to prevent system failure and increase life expectancy of the structure. 4. Handrails were missing from the alongside the elevated catwalk on the bridge between the tertiary tank and the aerator tank. The lack of handrails on this elevated structure could place a person in imminent danger of death or serious bodily injury and should be corrected immediately. 5. The visual alarm at the influent pump station needs to be repaired. The lightbulb was replaced during the inspection, so additional activities will be required to be performed to assess and repair this item. 6. Please remember that a renewal application should be submitted 6 months prior to the expiration Page# DocuSign Envelope ID: 3BCE6DB4-5739-495E-9B74-1 DA7EC916735 Permit: NCO047759 Owner -Facility: PruittHealth at Sealevel WWTP Inspection Date: 12/16/2021 Inspection Type: Compliance Evaluation of the existing permit (i.e. by 1/31/2022). Ms. Davis was very knowledgeable of the facility and the facility seemed to be well maintained although constant upkeep is required to deal with corrosive conditions. Records were reviewed and found to be detailed, well organized and complete. The facility is compliant with the discharge Permit NC0047759. Please review the comment sections of the inspection report for more details.
