We met with Wastewater Director, Joanne Massony. I presented my credentials to Ms. Massony and informed her that this was an EPA lead Compliance Evaluation inspection to determine compliance with the facility's National Pollutant Discharge Elimination System (NPDES) permit and the Clean Water Act. The scope of the inspection was with permit LA0066800, facility operations and maintenance under the Clean Water Act. The inspection was conducted under the authority of the NPDES permit program, in accordance with the Federal CWA. The information presented in this report is based on the materials and information supplied by City of Kenner (Owner) and Veolia (Operator), representatives (the permittee), observations made during the inspection and records and reports maintained by the permittee. FACILITY DESCRIPTION Treatment The City of Kenner facility in Kenner, Louisiana has one treatment plant. It is a 15.2 MGD activated sludge treatment plant. The plant consists of the original older 5.25 MGD activated sludge treatment plant (North Plant) that was opened in 1985, a 3.3 MGD activated sludge treatment plant (South Plant) that was opened in 1996. The North Plant was expanded by 5 MGD, during 2004 - 2006, with the addition of two (2) aeration basins and two (2) clarifiers. The site disinfects with sodium hypochlorite. The facility discharges to the Mississippi River via Outfall 001. Collection The City of Kenner collection system consists of gravity sewer pipes that discharge into 79 lift stations, of which six (6) directly discharge into the plant. The collection system has approximately 182 miles of 8inch gravity sewer pipe, 178 miles of 6-inch gravity sewer pipe, 31 miles of force main pipes and greater than 4,000 manholes. Section II- Observations This inspection revealed the following observations: On the day of the inspection the South Plant was down. The expected turnaround is 30 days from the day of the inspection. There has not been any exceedance of effluent limitation since 2014. The facility has sanitary overflows in the collection system and at the plant, summarized on the monthly discharge monitoring reports.
