NCDEQ Division Of Water Resources 1617 Mail Service Center Raleigh, North Carolina 27699-1617 Subject: Response for Permit No. WQ0016376 S&J Villari Processing Facility - Warsaw Wastewater Irrigation System Duplin County Dear Ms. Zhong, L�1 CAVANAU G H Stewardship Through Innovok. Cavanaugh & Associates, P.A., on behalf of S&J Villari Livestock (Villari), has reviewed your comments dated August 20, 2020, and has developed responses and additional supporting information to address each item in your comments. For your convenience, we have repeated the comments below in bold font, followed by the responses in italicized font. 1. The soils report included only 5 zones: Northwest of Zone 14, Zone 15, 16, 17 and 14. NW Zone 14 does not seem to be permitted right now. For Zone 14 - 17, the areas of each zone in the water balance sheets are not consistent with what were provided in the submitted soils report. For Zone 17, it was permitted in the Attachment B that the soils series is Bibby, whereas it shows as Lynchburg in the water balance sheet. Please clarify and provide the soils report that covers all zones. As we discussed on the phone Monday 8/10, the discrepancy between Bibby and Lynchburg in Zone 17 originates from the 2012 soils report. 'New Area 4' in the soils report is the same area as Zone 17, and the description of 'New Area 4'states that the "area consists of fill material over an original Lynchburg soil series" and that the 'fill material appears to be from... fine loamy soils" and 'fine sandy loam and loamy fine sand". While Zone 17 was ultimately permitted to label the dominant soil series as 'Bibby Sandy Loam'. the 2012 water balance listed 'Lynchburg, - no matter the designation of the soil series, the 'New Area 4' Ksat value of 0.043 in/hr will apply, so the numbers used in the water balance are accurate. Additionally, as we discussed, the values used in the updated water balance use the values from the 2012 soils report for the corresponding soil series for each zone; for example, Zone 1 is permitted as Norfolk, so the 2012 soils report Ksat value of 0.075 in/hr for Norfolk was used in the updated water balance. Lastly, as we discussed, the 2012 soils report area numbers do not correspond to the Zone numbers in the permit; i.e., as previously mentioned, 'New Area 4' is the same area as Zone 17. 2. The minimum required storage calculated on Page 29 of the response package was 8,570,580 gallons. However, about only 5.53 million gallons were permitted. Please clarify. As stated in our DWR response to Erick Saunders dated July 9, 2019: As was the case for the WWIS permit approved in 2013, the water balance shows a 'Minimum Required Storage' greater than the 5.53 MG existing storage on site (3.65 MG lagoon and 1.88 MG storage tank totaling to 5.53 MG), however, as was indicated in the May 17, 2013 DEQ cover letter for that approval, "the fields hydraulic and nutrient loading limits are the limiting factor for this facility'; so storage expansion was not considered. In other words, there were previous discussions with DWR that ultimately led to the 2013 approval based on the understanding that storage was not the issue and that the permit was limited by how much wastewater the irrigation fields could take. The referenced approval letter from 2013 has been included with this response. 3. Please provide the reference for the design daily flow (influent) of 99,080 gpd, located on the page 6 of the response package. The existing permit allows for a monthly average of 100,260 gpd total flow to all irrigation zones, so the 99,080 gpd is a back -calculation accounting for the gains and losses from precipitation and evaporation. Related to the answer to Comment #2 regarding storage, the 100,260 gpd was approved in 2013 based on how much wastewater the irrigation fields could take, Villari does not consistently utilize the full 100,260 gpd that their permit allows, but due to seasonality and the varying nature of the food production at the Villari facility, as well as sanitation restrictions imposed by USDA and NCDA, the flow varies, so it's permitted by the (near) maximum flow that can be supported by the irrigation fields. 4. Please update the site map to reflect Zones 14W and 14E. Zones 14W and 14E are labeled on the existing sheet, but they were not as obvious as they could be, so we've updated the plan sheet and it's attached with this response. Additionally, we noticed that we had erroneously deleted the "Zone 17" in a previous response, so it's been added back to the sheet. Additionally, per the inspection from Helen Perez on August 5, 2020, the size of the chlorine contact chamber that is directly downstream of the 1.88 MG aboveground storage tank has been labeled on the plans (the previous version of the plans labeled the tank, but didn't include it's size), and is attached with this response. It's our understanding that the chlorine contact chamber needs to be added to the description of the permit. Also as a result of the inspection, we have added to the plans the proposed pump station and forcemain that Villari is installing on the northern side of the lagoon. The lagoon currently operates by wastewater flowing into the lagoon on the north(west) side, and then it's removed from the lagoon using the pumps on the south(east) side that pumps to the 1.88 MG aboveground storage tank; Villari is adding a pump station with a single pump on the north side of the lagoon, as well as new piping and valves on the south(west) side of the lagoon, so that the wastewater flows into the lagoon at the south(west) and exits the lagoon at the north by the new pump station. They will keep the existing infrastructure in place as a back-up plan to the new pump station. The pump station calculations are included with this response, as well as the cut sheets from the pump manufacturer. Please do not hesitate to contact our office should you have any questions, comments, or require any additional information. Regards, Cavanaugh & Associates, P.A. Jeff P. Cappadona, P.E.
