NC0006351 I11 12I 20/06/10 117 18 i s i Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) This inspection was conducted as a joint inspection with Ms. Rose Pruitt of the Division of Waste Management's Hazardous Waste Section. Split samples for Chronic Toxicity were collected on June 9th and 11th, 2020. Results of Chronic Toxicity test well be sent under seperate cover. Discharge monitoring records were reviewed for a 12 month period May 2019 through April 2020. Review of 12 month compliance history revealed that facility did not discharge 8 of the 12 months reviewed. Discharge was reported in May/2019, January/2020, February/2020, and March/2020. Facilii reported an invalid Chronic Toxicity test, performed by Pace Labs, in January/2020. Records Review found Discharge Monitoring Reports (DM R's), laboratory analysis reports, chain of custody, calibration records, and operators logs well maintained and organized. Operation & Maintenance - It has been noted in past inspections that Lagoon #5 is becoming filled with settled solids. The large amount of solids has reduced setttling time and lagoon removal efficiency. Issues with Chronic Toxicity were reported in September and October 2017. This lagoon is unlined anc groundwater monitoring samples collected on 10/31/2019 from Monitoring Well (MW) #5 and #6, just down graident of lagoon, yeilded high levels of nitrates.
