The project will add one 8,000 gallon precast concrete flow equalization tank and interconnection pipe to the Zooland Family Campground Wastewater Treatment Facility. The project will not alter the current constructed treatment capacity of the facility (0.006 MGD) or the hydraulic profile. It will increase the flow equalization storage tank volume, from 2,000 gallons to 10,000 gallons. The project is needed due to the flow patterns that exist in the campground. Many of the RV campers with wastewater storage tanks will wait until they are leaving the campground to empty their storage tanks into the wastewater receiving station. Because the majority of these campers are on similar schedules (i.e., all leave on Sunday afternoon or evening, or after a special event at the campground, the treatment plant can receive a substantial flow surge at these times. These surges have proven to be harmful to the treatment process at times, causing shorter retention times for treatment, washing solids out of the clarifier, pushing excessive solids to the filters, etc. The proposed 8,000 gallon flow equalization tank will be interconnected to the existing 2,000 gallon flow equalization tank with a 4 -inch pipe. The existing pumps, level switches, and high water alarm will remain in the 2,000 gallon tank. Page 2of2 May 9, 2018 The following items are enclosed with this letter: • One set of construction plans, with specifications on the plans • One completed and signed original of the application form ATC 12-14 • Part I of the most recent NPDES permit, including Part A (Effluent Limitations and Monitoring Requirements) • Construction Sequence (on Sheet 1 of Plans) • One signed and sealed Engineering Calculation, checking the tank buoyancy • One CD with the information listed above, including a copy of this transmittal letter. Please advise if you require any additional information to process this request, or if you have any questions. Yours very truly, Diehl & Phillips, P.A. John F. Phillips, P.E.

(3.). 2. Upstream = at least 100 feet upstream from the outfall. Downstream = at NCSR 1127. There shall be no discharge of floating solids or foam visible in other than trace amounts. Page 4 of 7 Permit NCO089052 A. (3.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and specify that, if a state does not establish a system to receive such submittals, then permittees must submit DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates that these regulations will be adopted and is beginning implementation in late 2013. NOTE: This special condition supplements or supersedes the following sections within Part II of this permit (Standard Conditions for NPDES Permits): • Section B. (11.) Signatory Requirements • Section D. (2) Reporting • Section D. (6.) Records Retention • Section E. (5.) Monitoring Reports 1. Reporting [Supersedes Section D. (2.) and Section E. (5.) (a)1 Beginning no later than June 1, 2015 (270 days from the effective date of this permit), the permittee shall begin reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application. Monitoring results obtained during the previous month(s) shall be summarized for each month and submitted electronically using eDMR. The eDMR system allows permitted facilities to enter monitoring data and submit DMRs electronically using the internet. Until such time that the state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation (CROMERR), permittees will be required to submit all discharge monitoring data to the state electronically using eDMR and will be required to complete the eDMR submission by printing, signing, and submitting one signed original and a copy of the computer printed eDMR to the following address: NC DENR / DWR / Information Processing Unit ATTENTION: Central Files / eDMR 1617 Mail Service Center Raleigh, North Carolina 27699-1617 If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being physically located in an area where less than 10 percent of the households have broadband access, then a temporary waiver from the NPDES electronic reporting requirements may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be submitted to the mailing address above. Requests for temporary waivers from the NPDES electronic reporting requirements must be submitted in writing to the Division for written approval at least sixty (60) days prior to the date the facility would be required under this permit to begin using eDMR. Temporary waivers shall be valid for twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted electronically to the Division unless the permittee re -applies for and is granted a new temporary waiver by the Division. Page 5 of 7 Permit NCO089052 A. (3.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS, continued Information on eDMR and application for a temporary waiver from the NPDES electronic reporting requirements is found on the following web page: http://portal.nedenr.org/web/w A/admin/bog/ipu/edmr Regardless of the submission method, the first DMR is due on the last day of the month following the issuance of the permit or in the case of a new facility, on the last day of the month following the commencement of discharge. 2. SiLynatory Requirements [Supplements Section B. (11.) (b) and supersedes Section B. (11.) (d)] All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II, Section B. (11.)(a) or by a duly authorized representative of that person as described in Part II, Section B. (I 1.)(b). A person, and not a position, must be delegated signatory authority for eDMR reporting purposes. For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user account and login credentials to access the eDMR system. For more information on North Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please visit the following web page: http : //portal.nedenr. org/web/wq/admin/bo g/ipu/edmr Certification. Any person submitting an electronic DMR using the state's eDMR system shall make the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF CERTIFICATION WILL BE ACCEPTED: "I certify, under penalty of law, that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fines and imprisonment for knowing violations. " 3. Records Retention [Supplements Section D. (6.)] The permittee shall retain records of all Discharge Monitoring Reports, including eDMR , submissions. These records or copies shall be maintained for a period of at least 3 years from the date of the report. This period may be extended by request of the Director at any time [40 CFR 122.41].

THE VACUUM PUMP SHALL THEN BE STOPPED, AND THE PRESSURE OBSERVED FOR 5 MINUTES. THE TANK PASSES THE VACUUM TEST IF THE TANK HOLDS AT LEAST 90% OF THE VACUUM PRESSURE AT THE END OF THE 5 -MINUTE PERIOD. AT THE CONCLUSION OF THE TEST, THE VACUUM PRESSURE SHALL BE 67RADUAllY RELEASED. A WRITTEN REPORT OF THE TANK'S TEST SHALL BE PREPARED BY THE CONTRACTOR AND SUBMITTED TO THE ENGINEER. 7. THE CONTRACTOR SHALL THEN CORE DRILL THE REQUIRED OPENING FOR THE PIPE INTERCONNECTION TO THE EXISTING EQUALIZATION TANK.
