P.O. Box 9296 Greensboro, NC 27429-9296 Subject: Notice of Violation/Notice of Intent to Enforce(NOV/NOI) NOV-2018-PC-0085 Summerfield Shopping Center Wastewater Surface Irrigation Permit No.WQ0013808 Guilford County Dear Mr.Witcher: On January 30, 2018 Rebecca Chandler and Patrick Mitchell of the North Carolina Division of Water Resources(DWR)Winston-Salem Regional Office(WSRO)performed an announced routine compliance inspection and permit renewal site visit of the subject facility's wastewater treatment and surface irrigation system. WSRO staff were accompanied onsite by Mr. Chad Leinbach (ORC) and Mr. Parker Sheridan of Conner Consulting.A separate,in office review of the self-monitoring report records for the period September 2016 to December 2017 was also conducted.The inspection found the subject facility to be non-compliant with Permit No.WQ0013808. Accordingly, the following observations and violations were noted which require your immediate attention and action: 1. Permit Condition 1.4 states that"No later than six months prior to the expiration of this permit, the Permittee shall request renewal of this permit on official Division forms."The subject facility has been operating without a valid permit since the previous Wastewater Irrigation permit expired on August 31, 2017. A permit renewal was received by the NCDEQ Central Office on January 2,2018 and is currently under review. Until a new permit is issued,the subject facility shall operate within the conditions contained in the expired permit.The violations listed herein reference those conditions. 2. Permit Condition 11.1 states that"The surface irrigation facilities shall be effectively maintained and operated at all times so that there are no discharges to surface waters, nor any contravention of groundwater or surface water standards." During the inspection of irrigation Zone 1,the system began dosing. While WSRO staff were inspecting Zone 1 during the dosing, State of North Carolina I Environmental Quality 450 W.Hanes Mill Road,Suite 300,Winston-Salem,North Carolina 27105 Phone:336-776-98001 FAX:336-776-9797 Summerfield—NOV/NOI March 13,2018 Page 2 a flow of water was noted downslope of Zone 1 eventually discharging into surface water. It was later indicated during a follow-up phone conversation with the ORC that a manifold box from the wastewater irrigation system had broken in Zone 1 and that repairs were being made to stop the wastewater from leaking. Immediately review the entire wastewater irrigation system to ensure there are no additional leaks.Any additional leaks should be repaired immediately to prevent additional discharge to surface water. 3. Permit Condition 11.3 states that "Effluent limitations shall not exceed those specified in Attachment A." The permitted average flow rate of 3,182 gallons per day (gpd) was exceeded exponentially in December 2017 (8,951.6 gpd average). This permit condition was cited as a concern in the Compliance Evaluation Inspection letter dated August 24, 2015. Please provide reasoning for the increased flow rate in December 2017 and evaluate how this may be abated in the future. 4. Permit Condition 11.4 states that "Application rates, whether hydraulic, nutrient, or other pollutant shall not exceed those specified in Attachment B." The yearly maximum application for all application fields is 34.75 inches.This was exceeded on Fields 1 and 2 in September 2016, as well as in Field 3 in July 2017,August 2017,September 2017,October 2017, November 2017, and December 2017. Additionally, application was not ceased on Field 3 in July 2017, August 2017,and September 2017 even though the yearly maximum had already been exceeded.This permit condition was cited as a concern in a Notice of Deficiency dated October 26, 2011, as well as in the most recent two Compliance Evaluation Inspection letters dated August 24, 2015 and November 14,2016. Immediately begin utilizing the wastewater irrigation system within the permit condition limits. 5. Permit Condition 111.12 states"Freeboard in the wetland treatment cells and lined wet weather storage pond shall not be less than two feet at any time." Freeboard was recorded as 1.5 feet on May 23, 2017. In addition,questionable freeboard measurements(i.e.5'to 7'of freeboard within one week with no significant rainfall) were recorded in July 2017.This permit condition was cited as a concern in the most recent Compliance Evaluation Inspection letter dated November 14,2016. Be aware that Permit Condition IV.9(d) requires that WSRO be notified as soon as possible, but in no case more than 24 hours, or on the next working day any time self-monitoring information indicated the facility is no longer in compliance with permit limitations, i.e. freeboard. 6. Permit Condition 111.9 states "Public access to the land application sites shall be controlled." Fencing along Hwy 220 has yet to be replaced since NCDOT construction was completed. This Summerfield—NOV/NOI March 13, 2018 Page 3 permit condition was cited as a concern in the most recent two Compliance Evaluation Inspection letters dated August 24, 2015 and November 14, 2016. Repair fencing and/or restrictive signage to the facility to ensure no public access. 7. Permit Condition 111.2 states "Upon classification of the wastewater treatment and irrigation facilities by the Water Pollution Control System Operators Certification Commission (WPCSOCC), the Permittee shall designate...one or more certified operator(s) to be back-up ORC(s) of the facilities in accordance with 15A NCAC 08G .0200." During an in-office review of operator certifications, it was noted by WSRO staff that the backup ORC listed for the subject facility is not certified for the operation of wastewater irrigation systems. Note:the backup ORC is certified for biological wastewater treatment plant operation. Please ensure that the backup ORC obtains the proper certification for the system or designate a back-up ORC that possesses the proper certification as required by the permit. 8. Permit Condition 111.3 states that "A suitable year-round vegetative cover shall be maintained such that crop health is optimized, allows for even distribution of effluent, and allows for the inspection of the irrigation system." During the inspection, WSRO noted that numerous trees were dead and many of them had fallen across all of Zone 3, making inspection of the zone nearly impossible. Immediately remove the downed and falling dead trees from within Zone 3. Repair irrigation piping as necessary. 9. Permit Condition 111.11 states "Diversion or bypassing of untreated wastewater from the treatment facilities is prohibited." [15A NCAC 02T .0108(b)(1)] Three separate diversions or bypasses of partially treated wastewater were noted during the inspection. a) Wastewater was leaking from the sand filter treatment into the wet weather storage pond, bypassing a portion of the sand filter as well as the wetland treatment cells.The ORC indicated that this was a chronic issue and that the sand filter media may need to be replaced. b) A cap to an inline filter within the sand filter dosing station was missing causing wastewater to overflow from the pipe and bypass(this cap was purchased and replaced during the inspection by WSRO). c) A board was present within the level control flow splitter box which sends water to either the wet weather storage pond or directly into irrigation pump station.The board, as well as a debris clog,were blocking the weir to the sand filter,diverting a majority of the effluent directly into the irrigation pump station. Assess and resolve the problem causing the sand filter to bypass.Replace sand filter media if necessary with the proper material according to engineering specifications. Remove the Summerfield—NOV/NOI March 13,2018 Page 4 board from the weir and monitor debris build-up within the level splitter box so that the system may operate as designed. 10. Permit Condition 111.13 states that"Waste-level gauges,to monitor waste levels in the wetland treatment cells and lined wet weather storage pond,shall be provided.These gauges shall have readily visible permanent markings indicating the maximum liquid level at the top of the temporary liquid storage volume, minimum liquid level at the bottom of the temporary liquid storage volume, and the lowest point on the top of the dam elevations." Additionally, Permit Condition 1.3 states that waste-level gauges should have been installed "...within 60 days of the issuance of this permit for the wetland treatment cells and prior to the operation of the wet weather storage pond."This permit condition was cited as a concern in a Compliance Evaluation Inspection letter dated August 24,2015. Immediately install and maintain a staff gauge within the wet weather storage pond. Be aware that the new permit for the subject facility will likely require staff gauges to be marked to the tenth of a foot. 11. Permit Condition IV.5(R)states the records to track wastewater disposal "shall include, but are not necessarily limited to...weather conditions." Upon review of self-monitoring data, it was noted that weather codes and precipitation events are only recorded once weekly. Please ensure that weather codes and precipitation levels are recorded for each irrigation event as required by the permit. In addition to the above-mentioned violations, the following items of concern also require your attention and action: 1. During WSRO staff's inspection of wastewater treatment property,the alarm for the sand filter dosing box was going off. The cause of the alarm was unclear at the time. The cause of this alarm should be identified and resolved immediately. 2. WSRO noted that a small willow tree had begun to grow within one of the wetland treatment cells. This tree must be removed immediately before rooting punctures or weakens the integrity of the cell lining. 3. It was noted by the ORC that power is periodically turned off to wet weather storage.WSRO is concerned that any alarms connected to the wet weather storage pond may not operate when necessary if power is not maintained. Ensure that power is connected to all parts of the wastewater system so that the system may operate as designed. DWR staff was contacted by the ORC on February 13,2018 regarding repairs being made to the system, as well as additional system failures/non-compliance concerns that had occurred since the inspection. Summerfield—NOV/N01 March 13,2018 Page 5 Required Response: Accordingly, you are requested to provide a written response within ten (10) calendar days following receipt of the Notice.Your response should be sent to my attention at the letterhead address and must include an outline detailing specific plans to remedy these violations and any future violations.

The following violations were noted during the inspection: Bypass within in-line filter to sand filter Bypass from sand filter into wet weather storage pond Bypass from the level splitter box from the wet weather storage(board present in weir as well as debris buildup,diverting water solely to pump house) Failure to renew permit—operating under expired permit Backup ORC is not certified for drip irrigation Daily average flow rate exceeded in December 2017 12-Month loading rate exceeded in Field 3 in July 2017,August 2017, September 2017,October 2017, November 2017,and December 2017. Freeboard level was exceeded in May 2017—there are questionable freeboard levels in July 2017(5'to 7'within a week) Public access is still no restricted from the site Runoff noted from Zone 1 during dosing,flowing downslope towards surface water Staff gauge not present in wet weather storage pond. PVC pipe being used as freeboard marker,but not marked to the tenth of a foot Zone 3 was inaccessible due to dead trees both downed and still leaning up. Additional concerns include: Alarm at sand filter dosing box was activated during inspection with no clear cause Small willow growing in wetland cell Power being turned off to wet weather storage periodically A full review of onsite records was not completed during this inspection due to time constraints.A separate,permit renewal site inspection was completed in conjunction with this compliance inspection.
