Dear Mr. Carkido:

RE: RED FOX WWTPPERMIT NO. 3PH00037PORTAGE COUNTYSHALERSVILLE TOWNSHIP

On December 7, 2011 an inspection of the above referenced facility was conducted. Thefacility was represented by Mr. Don West, Class IV Superintendent and you. The purpose of theinspection was to: (1) evaluate the performance of the wastewater treatment system along withthe facility's compliance status with respect to the terms and conditions of the above-referencedNational Pollutant Discharge Elimination System (NPDES) permit and (2) determine requiredadditional actions to be undertaken as part of the permit renewal process.

During the inspection, the following items were noted/discussed:

1. The plant design of the wastewater treatment system is 160,000 gpd.2. In accordance with Ohio Administrative Code (OAC) 3745-7-04, the sewage

treatment facility is classified as a Class II facility. Once the facility's permit isrenewed, the permittee shall ensure that the treatment works operator of record isphysically present at the facility five times per week for a minimum of twenty hoursper week.

3. The trash trap is pumped out every 7-10 days.4. Detail plans (permit-to-install [PTI] application number 802314) for influent screening

equipment to replace the existing influent trash trap was approved on April 1, 2011.5. The blowers were running and the plant was receiving good aeration.6. The sludge digester was also being aerated.7. The aeration portion of the treatment system was comprised of an East and West

tank.8. The contents of the aeration tanks were orange-ish brown in color. A small amount of

foam was present on the surface of both tanks. You indicated that the foam is notalways present in the tanks. The cause of the orange-ish color is caused by theaddition of ferric chloride.

9. Both skimmer return lines were working properly and returning clear water.10. Both sludge return lines were working properly and were returning medium brown

water.11. The weirs and the sidewalls in the settling tank were free of scum/solids build-up.12. The treatment system has two IDI tertiary sand filters. Both were operational.13. The treatment system is also equipped with an Ultra Violet disinfection unit. The

system is functional. However, it is not required to be operated this time of year.
