Permit Number WQ0002005 Rose Hill, Duplin County, North Carolina Protocol Sampling Service, Inc. Job No. 99-040 Dear Ms. King: Protocolsampling@yahoo.com Enviro=entalservicesnc.com This report will entail an overview of the wastewater effluent concentrations; trends associated with the weekly, monthly and yearly loading rates and plant available nitrogen (PAN) concentrations for the first ten months of 2019. Protocol Sampling Service, Inc. personnel visited the site on Tuesday, September 3, 2019. Irrigation was not taking place at the time of the September 3rd inspection due to light rainfall. Due to a more normal rainfall year to date (YTD) total of 45.60 inches compared to 73.45 inches of rainfall received in 2018 YTD grass production has drastically increased from this time last year; 616 round bales of rye and Coastal Bermuda grass had been harvested in 2018, whereas 1850 bales have been harvested this year. Duplin County usually receives about 51 inches of rain in an average year. The House of Raeford plant lagoons and land application areas received 96.55 inches of rainfall in 1999. The plant lagoons and spray fields received 43.04 in calendar year 2000, 39.3 inches in calendar year 2001, 40.33 inches in calendar year 2002, 66.40 inches in calendar year 2003, 52.45 inches in calendar year 2004, 52.30 inches in 2005, 73.40 inches in 2006, 41.30 inches in 2007, 58.0 inches in 2008, 50.15 inches in 2009, 52.08 inches in 2010, 42.11 inches in 2011, 50.15 inches in 2012, 54.80 inches in 2013, 48.98 inches in 2014, 67.35 inches in 2015, 71.05 inches in 2016 and 52.60 inches in 2017. The rainfall received through October 2019 has decreased by 27.85 inches when compared to the rainfall received during the same time period in 2018 (45.60 vs. 73.45 inches). A total of 84.95 inches of rainfall was received in calendar year 2018 due to 26.10 inches of rainfall received in September 2018 with 20.4 inches delivered by Hurricane Florence on September 13-15, 2018. The secondary lagoon laboratory data had shown a 46% increase in average TKN and a 39% increase in NH3 concentrations when comparing the year to date (YTD) 2014 to the 2013 data. The NO3-N concentrations averaged a low 0.15 mg/l. The secondary lagoon laboratory data had shown a 40% decrease in average TKN and a 42% decrease in NH3 concentrations when comparing the 2015 to the 2014 YTD data. The NO3-N concentration averages a relatively low 0.49 mg/l. The secondary lagoon laboratory data had shown a 1% decrease in average TKN and a 3% increase in NH3 concentrations when comparing the 2016 to the 2015 YTD data. The secondary lagoon laboratory data had shown a 20% decrease in average TKN and a 26% decrease in NH3 concentrations when comparing the 2017 to the 2016 YTD data. The NO3-N concentration averages 1.09 mg/l due to a spike in the October and November lab analyses. The secondary lagoon laboratory data had shown a 3% increase in average TKN and a 2% increase in NH3 concentrations when comparing the 2018 to the 2017 YTD data. The secondary lagoon laboratory data had shown a 9% decrease in average TKN and an 8% decrease in NH3 concentrations when comparing the 2019 to the 2018 YTD data. The primary and secondary lagoons are now able to adequately treat the nitrate portion of the waste stream before it is applied to the spray fields. The average yearly PAN loading which had fallen from 275 #/acre in 1999 to 205 #/acre in 2000, increased to 294 #/acre in 2001. The PAN loading decreased to 247 #/acre in 2002, to 228#/acre in 2003, increased to 250#/acre in 2004, increased to 321#/acre in 2005, decreased in 2006 to 244#/acre, increased in 2007 to 295#/acre, 255# in 2008, 246# in 2009, 216#/acre in 2010, 207#/acre in 2011, 199#/acre in 2012, 261#/acre in 2013, 291#/acre in 2014, 151#/acre in 2015, 126#/acre in 2016, 132#/acre in 2017 and 127#/acre in 2018. The 2019 average yearly PAN loading is on track to average 63#/acre if the existing 2019 data is extrapolated. At the time of the inspection, the secondary lagoon freeboard was observed to be 3.83 feet and has decreased slightly to 3.35 feet at the end of October 2019. The interior sidewalls were grassed and no erosion was evident. No algae build-up was evident on the lagoon water surface. Even though wastewater production has fluctuated recently, Mr. Teachey has been able to maintain the spray fields and equipment including the grassed waterways and buffers, which continue to be in excellent shape. The weed colonies, especially chickweed (Stellaria media) that were treated with 2, 4 — D and MSMA previously had returned and were mechanically removed from the center pivot (4CP) and the field was reseeded with coastal Bermuda grass which has reestablished a healthy cover crop. A summer season with normal rainfall amounts has caused a 300% increase in grass production from this time last year; 1850 round bales of rye and Coastal Bermuda grass has been harvested in 2019 whereas 616 bales had been harvested in 2018 YTD. 1,918 bales of rye and Bermuda grass were removed in 2017. 2,384 bales of rye and Bermuda grass were removed in 2016. 2,029 bales of rye and Bermuda grass were removed in 2015. 2,301 bales of rye and Bermuda grass were removed in 2014. 2,111 bales of Rye and Bermuda grass were removed in 2013, 1,000 bales of Rye grass were removed in 2012, 1,224 bales of Rye grass were removed in 2011, 1104 bales of Rye grass were removed in 2010, 803 bales of Rye grass were removed in 2009, 356 bales of rye grass were removed in 2009, 1,088 bales of rye grass were removed during the same period in 2007, 1,470 round bales were removed in 2006, 1,800 round bales were harvested in 2005 and 2,475 round bales of rye grass hay were harvested in 2004. 853 round bales of rye grass hay were removed from the fields in 2003 and 1,243 round bales of rye grass hay were removed from the fields in 2002. All of the hay bales are being picked -up by local farmers for cattle feed. Two composite soil samples from the two largest fields (CP 4 and laterals) were collected for agronomic analysis by Waypoint Analytical (formerly A&L Eastern Laboratories) located in Wilson, North Carolina. The Soil Test Report by Waypoint Analytical is attached. Agronomic analysis has revealed that the site soils have an average cation exchange capacity of 9.05 (8.15 in 2018, 4.77 in 2016) and an average pH of 6.00 (6.25 in 2018, 5.60 in 2016) which indicates that the mineral site soils continue to hold the cations Calcium, Magnesium, from past applications of lime. Base saturation averaged 85 (82.50% in 2018, 60% in 2016) and these soils will respond well to subsequent fertilization events. The phosphorus index, which averaged 215 (129.50 in 2018, 81.70 in 2016), and the potassium index average of 22.0 (21.50 in 2018; 13.33 in 2016) are high and moderate, indicating that additional potassium will be need to be applied at 185#/acre. Lime will not be needed due to the high base saturation and neutral pH values reported for these fields. Nitrogen should be added at 220 #/acre and applied early next season prior to application of waste water to help jump start the existing cover crop. A foliar sample was taken from recently removed hay and sent to the Waypoint Analytical located in Leola, Pennsylvania for a plant analysis plus Total Nitrogen. The Test Report by Waypoint Analytical is attached. Chemical analysis has revealed a Crude Protein percentage of 10.8 which is excellent for forage with 12% being optimal (6.51% in 2006 and 12.17% in 2002). At this concentration approximately 30-35# nitrogen/acre is being removed from the spray fields. The DAF waste water pretreatment system continues to effectively treat the waste water stream and keep the 4114 Laurel Ridge Drive Raleigh, North Carolina 27612 4 R CERTIFIED ani.i rr Protocol Sampling Service, Inc.

A spike in the NO3-N concentrations in June of 7.10 mg/l has returned to normal but any spike needs to be watched. Due to a return to average rainfall amounts and frequency even with a fluctuation in waste water strength, grass production has increased to normal levels. but an increase in wastewater volume application could be initiated on spray fields L2, L3 L5, L6 -L9, 6A and 6B to maintain a sufficient crop nutrient load for maximum production while maintaining a safe hydraulic loading. Average PAN should not exceed 75#/acre if current PAN/acre concentrations are extrapolated. Overall, an exceptional improvement in waste water treatment continues to be maintained by House of Raeford, Inc. plant personnel.
