Jimmy Holland, PE Project: Family Dollar WWTF - Currie Client: Cedar Run Capital Project No.: 08721-0001 Date: August 16, 2022 Subject: Responses to NCDEQ DWR Comments NCDEQ Comments and M&C Responses: C1. NCDEQ Comment: In Section II, the provided address of 2844 Caratoke Highway and the provided facility coordinates of 34.44o, -78.05o do not appear to correspond to the parcel referenced in the submittal documents. Please revise the facility information to include the address associated with the proposed facility, and please revise the coordinates to a higher level of accuracy (preferred accuracy is to the nearest tenth of a second or six decimal points). M&C Response: The address on the application in Section II has been updated to 9240 Hwy 421, Currie, NC, 28435 to correspond with the parcel referenced on the property deed in the resubmittal documents. The coordinates have also been updated to six decimal points. C2. NCDEQ Comment: Item IV.7 lists that representative data and a flow reduction approval were used for the proposed facility’s wastewater flow. A value of 260 gallons per day (GPD) was listed for the business; however, it is unclear what data was used to determine this flow as this facility and the associated business have not yet been constructed. Additionally, a copy of the flow reduction approval letter was not included within the submittal package. Please provide additional information regarding the daily design flow of the proposed wastewater facility that meets the requirements of 15A NCAC 02T .0114(c) and a copy of the flow reduction approval letter issued by the Municipal: NPDES, Pretreatment and Collection Systems Unit. M&C Response: A copy of the flow reduction approval letter including data used to determine the flow at this facility and the associated business is included within the resubmittal package. C3. NCDEQ Comment: Item IV.9 indicates that documentation of the presence or absence of threatened or endangered aquatic species was provided. This documentation was not included in the submittal package. Please provide the missing document. M&C Response: Item IV.9 on the application has been revised and is now unchecked. An information request has been submitted to the North Carolina Natural Heritage Program. Documentation of the presence or absence of threatened or endangered aquatic species is being acquired and will be sent once received. C4. NCDEQ Comment: Item IV.10 lists an active monitoring well (Monitoring Well 1). Please provide a copy of the Well Construction Record (Form GW-1) so that we can add this well to the permit records. If the well has not been constructed, then please revise the application to indicate that the monitoring well is “proposed”. M&C Response: Item IV.10 has been revised to indicate the monitoring well is “proposed.” The plan set has been revised to include the proposed monitoring well, MW-1. C5. NCDEQ Comment: Item V.1, the “Designed Effluent Concentrations” column lists values of less than the permit limits outlined in 15A NCAC 02T .0505 for the designed effluent parameter rather than supplying values representative of the proposed plant’s nutrient and constituent removal capacity. Please provide either removal calculations that demonstrate what this treatment facility should be capable of achieving or effluent study data from Advantex systems serving comparable influent waste streams. Please revise the application as needed. M&C Response: Effluent study data from Advantex systems serving comparable influent waste streams is attached as is the hydraulic and pollutant loading spreadsheet. A summary of median effluent values from an Advantex internal sample are summarized in the table below. The sample includes residential of all varieties, 2 bedrooms to 12 bedroom oceanfront, community systems and commercial, totaling 515 sample sites. INF TKN Effl cBOD Eff TSS Eff NH3 Eff TKN Eff NN Total Eff N Eff % Nit Red Eff Fecal Effl Turbidity Median=55.4 2.0 2.5 1.6 3.5 16.9 21.7 56%10.0 3.6 The “Designed Effluent Concentrations” column in Item V.1 has been revised to supply values representative of the proposed plant’s nutrient and constituent removal capacity based on the values in the above table. C6. NCDEQ Comment: The response to Item V.5 states that an activated standby power supply will be made available onsite to satisfy 15A NCAC 02T .0505(l). The response under Item IX.5 indicates that an automatically activated standby power source will not be provided. Please address this discrepancy and provide additional information regarding the Power Reliability Plan. M&C Response: An automatically activated standby power source will not be provided. Item V.5 has been revised to reflect this and there is no longer a discrepancy with Item IX.5. There will be enough effluent storage available as determined by the storage calculations described in M&C response to NCDEQ’s comment M.1. Additionally, there will be a hook-up for a portable back-up generator that can be obtained during instances in which a generator will be needed. More information on the Power Reliability Plan has been provided in the General Process Description, Operation and Maintenance Plan, Residuals Management Plan, and Power Reliability Plan attached. C7. NCDEQ Comment: Earlier in the application, it was indicated that 15A NCAC 02T .0505(k), which requires multiple pumps be provided wherever pumps are used, is being met. Section V.11.e indicates that only one effluent pump is being installed in the pump tank. How is the applicant intending on complying with .0505(k)? M&C Response: Multiple pumps will be provided wherever pumps are used. Section V.e has been updated to reflect this. C8. NCDEQ Comment: Item VII.1 of the application states that the minimum depth to the Seasonal High Water Table (SHWT) within the proposed irrigation area is 2.72 feet. This measurement does not appear to agree with the Soil Evaluation report provided by Applied Resource Management, P.C. which indicated that the water table may be within 12 inches of the surface. Please revise or explain the discrepancy. M&C Response: In the report provided by Applied Resource Management, P.C., Monitoring Well 1 indicated static water at 10”, Monitoring Well 2 indicated static water at 11”, and Monitoring Well 3 indicated static water at 8”. However, as the vertical separation between the seasonal high water table and the ground surface must be at least one foot, 24” of fill will be provided in the irrigation area. Item VII.1 of the application has been updated to state that the minimum depth to the Seasonal High Water Table (SHWT) within the proposed irrigation area is 2.67 feet (32 inches). D1. NCDEQ Comment: The submittal package included a document titled “Assignment of Rents” between Cedar Run Capital, LLC (the applicant) and Truist Bank that refers to parcel 2285-63-0939- 0000. The "Assignment of Rents" document does not appear to meet the requirements of 15A NCAC 02T .0504(f), and a review of the Pender County Register of Deeds GIS map shows that Parcel number 2285-63-0939-0000 is owned by Rudy Johnson. Additionally, Mr. Johnson does not appear to be affiliated with Cedar Run Capital, LLC. Please demonstrate that the requirements of 15A NCAC 02T .0504(f) are being met by providing one of the following: a) Legal documentation of ownership (i.e., GIS, deed or article of incorporation), b) Written notarized intent to purchase agreement signed by both parties with a plat or survey map, or c) Written notarized lease agreement that specifically indicates the intended use of the property and has been signed by both parties, as well as a plat or survey map. Lease agreements shall adhere to the requirements of 15A NCAC 02L.0107. M&C Response: The legal documentation of ownership (property deed) for parcel 2285-63-0939- 000 and 2285-54-9493-000 is attached to this submittal package. E1. NCDEQ Comment: Saturated hydraulic conductivity (Ksat) values were only provided for depths of 22 to 40 inches and 66 to 84 inches. The Murville Muck series, as described in the “Soil Survey of Pender County, North Carolina”, includes a mucky fine sand in the A horizon. The provided engineering design indicates that the existing soils are to remain in situ, and hydraulic conductivities were not provided for the full soil profile. Indications of a shallow groundwater table were noted throughout the Soil Evaluation, and it is unclear whether the values depicted in Table 1 are representative of the most restrictive soil horizon at the site. Please provide additional information regarding the saturated hydraulic conductivity in the upper 22 inches of the soil profile. M&C Response: See attached Applied Resource Management report for comment response and additional information. E2. NCDEQ Comment: Within the Soil Evaluation, a maximum daily design flow of 200 gallons per day (GPD) is provided based on the preliminary water balance data with a note that the maximum daily design flow may be limited by nutrient loading rather than hydraulic loading. The loading rate analysis section indicates that phosphorus removal is the limiting design criteria and provides a maximum loading rate of 70.8 inches per year. The loading rate of 70.8 inches per year for a 0.08-acre disposal area appears to correspond to approximately 420 GPD – this is reflected in the Daily Design Flow calculation in Appendix B. The engineering design for this application uses a daily design flow of 260 GPD. It is unclear what the basis is for the 200 GPD recommended in the Soil Evaluation, and whether the proposed engineering design daily flow of 260 GPD is attainable for the current site conditions. Please address the inconsistencies between the daily design flow requirements and provide additional information as needed. M&C Response: See attached Applied Resource Management report for comment response and additional information. H1. NCDEQ Comment: The provided water balance was termed a “Quick Water Balance Assuming No Storage”. It is unclear how nutrient management, required pursuant to 15A NCAC 02T .0504(k), has been incorporated into the provided water balance. The maximum allowable irrigation depicted shows considerably higher values than the 259 gallons per day listed in the Totals row. Please provide additional information regarding the water balance. M&C Response: The provided water balance was calculated using the NC DENR Division of Water Quality Version 5 Water Balance Excel Program. The water balance program was designed to assist permit applicants in meeting the minimum design requirements of NCAC 15A.2H.0200 for surface irrigation disposal/treatment systems. The soil drainage methodology used within this program is referenced from EPA 625/1-81-013, Process Design Manual, Land Treatment of Municipal Wastewater. In order to complete this procedure, actual in-situ saturated vertical hydraulic conductivity values for the soils under consideration to receive wastes are required as well as facility design data, long term precipitation data, and long term temperature data. The maximum allowable irrigation total was revised to depict the correct amount of the sum of the maximum allowable irrigation of the 12 months, 94,364 gpd. The revised water is attached. I1. NCDEQ Comment: The provided Plan Set appears to have been resized during the submittal process rendering many of the finer notes and features illegible. Please submit a copy of the revised Plan Set via email in addition to your electronic submittal for the response to this letter so that our staff can confirm that the depicted facility corresponds to the provided engineering calculations and design. M&C Response: A copy of the revised Plan Set has been provided via email in addition to the electronic resubmittal. I2. NCDEQ Comment: Several of the submitted documents indicated that Irrigation Field Notes 1 and 2 on Sheet G101 conflict with the Fill System Detail provided in the Soil Evaluation report. The Fill System Detail calls for 24 inches of approved sand fill, while the Plan Note calls for 18 inches. Similarly, the Fill System Detail states that fill material should be tapered from the top edge of the fill to the ground surface 6 feet from the boundary area, while the Plan Note calls for 5 feet. M&C Response: The Irrigation Field Notes 1 and 2 on Sheet G101 have been updated to correspond with the Fill System Detail provided in the Soil Evaluation report. I3. NCDEQ Comment: Sheet C101 depicts a pond and a temporary skimmer basin near the proposed treatment plant and irrigation facility. The scale on the provided plan set is difficult to discern, but it appears that these features are within the setback limits outlined in 15A NCAC 02T .0506. The Soil Evaluation provided by Applied Resource Management, P.C., recommended reconstruction of the pond to provide for the proper setback distance; however, this does not appear to be reflected in the provided Plan Set (or other engineering documents). Additionally, it is unclear whether the temporary skimmer basin will still be in operation at the time of facility start-up. Please provide additional information regarding these structures including anticipated cease of operation, reconstruction, and any additional actions necessary to meet the setback requirements. M&C Response: The scale of the plan set will be easier to discern with the plans emailed separately. As seen on sheet C103, the temporary skimmer basin is outside of the treatment system 50 foot surface water setback limit and outside the 100 foot surface water setback limit for the irrigation site. The temporary skimmer basin is a proposed structure that will be built during the Family Dollar Building project. Notes have been added to the relative sheets to reflect Applied Resource Management, P.C. recommendation to fill a portion of the pond to provide the proper setback distance for the irrigation site setback requirement. I4. NCDEQ Comment: A sufficiently detailed view of the pump tank was not provided within the submitted Plan Set. Please include a detail that depicts the screened vent, as well as a depiction of the controls, alarms, and proper signage. M&C Response: The detailed view of the pump tank is provided on sheet M100. Additionally, the product data sheet is included in the resubmittal. I5. NCDEQ Comment: Please provide a trench detail for piping installation and a detail for the compliance monitoring well. Please note that monitoring wells are to be constructed in accordance with the 15A NCAC 02C rules. M&C Response: A trench detail for piping installation and a detail for the compliance proposed monitoring well have been included on Sheet D101. J1. NCDEQ Comment: The Engineering Plans and Soil Evaluation indicate that specialized earthwork is needed to construct the drip irrigation area. Please provide specifications for the construction of the drip irrigation mound area, including the type of soil to be used as backfill, methods used to place the soil (e.g., tilling, discing, etc.), and any other necessary considerations. M&C Response: Section 12000 – Construction of the Drip Irrigation Mound has been added to the technical specifications on page TS-29. Therein includes the type of soil to be used as back fill (Soil Group I sandy fill), subsection 1.02 Placement Fill which details methods for soil placement, and other necessary considerations including site preparation and final landscaping. J2. NCDEQ Comment: On page TS-4, Subpart 1.09 Equipment states that the Contractor may use any type of earth-moving, compaction, and watering equipment. Additional considerations are required for earthwork and preparation activities in the proposed disposal area to preserve soil structure. Please revise this section to adequately reflect separate requirements for earthwork activities within the proposed disposal area. M&C Response: Section 02300 – Earthwork subpart 1.09 Equipment on page TS-5 of the Technical Specifications has been revised to state that the Contractor may use any type of earth-moving, compaction and watering equipment that will minimize detrimental impacts to the irrigation area. J3. NCDEQ Comment: Page TS-9 discusses fertilizer application in advance of seeding, but the specifications do not appear to distinguish between the drip irrigation areas and the landscape areas of the property. The proposed fertilizer is 8-8-8 which will result in further phosphorus loading to the proposed disposal area and is not suitable for a site where phosphorus removal is the limiting design criteria. Please revise this section to adequately reflect separate requirements for seeding and turfing the drip irrigation areas. The Non-Discharge Branch also requests that the proposed seed mixtures for the irrigation area cover crop be described therein. M&C Response: The subsection on fertilizer in Section 02320 – Seeding and Turfing has been removed. The proposed seed mixtures for the irrigation area cover crop is described in Section 12000 – Construction of the Drip Irrigation Mound subsection 1.03.B Final Landscaping of Fill System on page TS-29 of the Technical Specifications. J4. NCDEQ Comment: TS-18 describes the high-head effluent pumps, but a few parameters were not included. Please include the proposed pump operating point. M&C Response: Section D.11 on page TS-18 of the technical specifications has been revised to include the proposed pump operating point of 30 gpm and 55 ft total dynamic head. J5. NCDEQ Comment: The specifications for the disinfection system list only that it is to be accomplished by ultraviolet disinfection. Please provide details including the number of banks, the number of lamps per bank, and the maximum disinfection capacity. Please also include product sheets of the selected system or a list of acceptable manufacturers. M&C Response: Language has been added to Section 11000 – Treatment Units subsection F – Disinfection. There are a total of two UV banks and two UV bulbs, one UV bank per AX20 pod, and one UV bulb per bank. The unit’s maximum disinfection capacity is also further explained in this section. The Orenco® AXUV Disinfection Unit product sheet is attached. K1. NCDEQ Comment: Several calculations were not included in the submittal. Pursuant to 15A NCAC 02T .0504(c)(3), the engineering calculations should include hydraulic and pollutant loading for each treatment unit, treatment unit sizing criteria, hydraulic profile of the treatment system, total dynamic head, and system curve analysis for each pump, buoyancy calculations, and irrigation design. Please revise the calculations to include the hydraulic and pollutant loading for each treatment unit, treatment unit sizing criteria, the hydraulic profile of the treatment system, and the system curve analysis depicting the pump curve and operating point. M&C Response: The engineering calculations now include the hydraulic and pollutant loading for each treatment unit, the treatment unit sizing criteria, and the system curve analysis depicting the pump curve and operating point. The treatment system hydraulic profile is located on sheet C104. For the treatment sizing criteria, the Advantex representative commented, “The reality is that we don't have a great way to model effluent performance on such a small flow with so much textile on it. As you can see, the flow only technically requires 10 sq ft of textile to meet the effluent requirements detailed on the sheet. This design has 40sq ft of textile on it. I would expect BOD5 to be <2mg/l, NH3 <2mg/l, TN of around a 60-70% reduction over the influent TKN.” The representative also provided a summary of median effluent values from an internal sample set as well. This includes residential of all varieties, 2 bedrooms to 12 bedroom oceanfront, community systems and commercial, totaling 515 sample sites. The results are summarized in the table below. INF TKN Effl cBOD Eff TSS Eff NH3 Eff TKN Eff NN Total Eff N Eff % Nit Red Eff Fecal Effl Turbidity Median=55.4 2.0 2.5 1.6 3.5 16.9 21.7 56%10.0 3.6 L1. NCDEQ Comment: It appears that Plan Sheet C101 is meant to serve as the Site Map for this permit application. This sheet was missing several of the features required under 15A NCAC 02T .0504(d). Please include the monitoring well (i.e., MW-1) and label the disposal zones (i.e., Zone 1 and Zone 2) so that the Site map corresponds with the information provided in the application form. Please revise as needed. M&C Response: Plan Sheet C101 has been incorporated into the sheet set as the Site Map and all features required under 15A NCAC 02T .0504(d) are included. The monitoring well is displayed and disposal zones 1 and 2 are labeled. Sheet C102, originally sheet C101 - Proposed Site Plan is included to provide a closer view of the irrigation and project site. M1. NCDEQ Comment: A Power Reliability Plan was not included in the submittal. On the application checklist, the checkbox for “Has sufficient storage capacity that no potential for overflow exists” is checked. A storage calculation was not provided within the submittal package, and further information is needed for approval from the Director. Please provide additional information within the Power Reliability Plan document that meets the requirements of 15A NCAC 02T .0505(l). M&C Response: Information on the Power Reliability Plan has been provided in the General Process Description, Operation and Maintenance Plan, Residuals Management Plan, and Power Reliability Plan attached. An automatically activated standby power source will not be provided because there will be enough effluent storage available as determined by the following storage calculation. 1500 𝑔𝑎𝑙𝑙𝑜𝑛𝑠 260 𝑔𝑝𝑑=5.77 𝑑𝑎𝑦𝑠 𝑜𝑓 𝑠𝑡𝑜𝑟𝑎𝑔𝑒 The storage tank has the capacity for 1,500 gallons. At 260 gpd, this would provide 5.77 days of storage. Additionally, there will be a hook-up for a portable back-up generator that can be obtained during instances in which a generator will be needed. N1. NCDEQ Comment: Pursuant to 15A NCAC 02T .0507(a)(4), the Operation & Maintenance (O&M) Plan shall include spill control provisions, including (but not limited to): response to upsets and bypasses, including control, containment, and remediation; and contact information for plant personnel, emergency responders, and regulatory agencies. M&C Response: An Operation & Management Plan is included in the attached document titled General Process Description, Operation and Maintenance Plan, Residuals Management Plan, and Power Reliability Plan. N2. NCDEQ Comment: The Drip Irrigation System O&M Manual states "See the following pages for specific maintenance tasks and troubleshooting guidelines". However, no additional pages were provided. Please review and revise. M&C Response: Additional pages have been provided and are attached. N3. NCDEQ Comment: The ultraviolet (UV) disinfection system did not appear to be included within the provided product manuals. Please provide the appropriate Operation & Maintenance information for the proposed UV disinfection system. M&C Response: The appropriate Operation & Maintenance information for the proposed UV disinfection system is attached. O1. NCDEQ Comment: A Residuals Management Plan was not included in the submittal. Pursuant to 15A NCAC 02T.0504(j) and .0508, submit a Residuals Management Plan that includes, at minimum: a. A detailed explanation of how generated residuals (including trash, sediment and grit) will be collected, handled, processed, stored, treated, and disposed. b.

BENTON • Assistant Secretary for Public Health Division of Public Health To: North Carolina Environmental Health Specialists From: Jon Fowlkes, On -Site Water Protection Branch Head Subject: Updated Design Flow Reductions for Dollar General Date: May 24, 2021 Based on additional data sets provided for Dollar General Stores, the following adjusted design daily flows may be used: Up to 8,000 square feet of retail sales floor— 200 gpd Retail sales floor from 8,001 square feet to 10,000 square feet — 240 gpd Retail sales floor from 10,001 square feet to 12,000 square feet — 260 gpd The adjusted design daily flows can only be used with the following conditions: 1. Tanks must be sized on the un-reduced design flow (120 gpd/1,000 square feet of retail space area). 2. Use of low -flow fixtures such as spring -loaded or automatically activated faucets with flow rates of one gallon per minute or less, low -flow urinals which use 0.5 gallons per flush or less, and low -flow toilets which use 1.28 gallons per flush or less. Cut sheets of the fixtures must be provided. 3. A floor plan of the building must be provided, identifying the retail sales floor square footage. 4. If a pump system is used, a Branch -approved flow equalization control panel must be used. The flow equalization control panel limits the amount of effluent discharged to the dispersal field to be no more than the maximum adjusted design daily flow. When the lag float is triggered, only one timed dose is delivered. Non -flow equalization control panels are programmed to discharge all effluent in the pump tank to the dispersal field when the lag float is triggered. S. The tenants are prohibited from disposing into the wastewater system any chemical cleaners or any other compound which may be harmful to the bacteria in the wastewater system, including but not limited to quaternary ammonia compounds. 6. The tenants are prohibited from disposing of any food waste (solid or liquid) into the system. 7. The improvement permit, authorization to construct, and operation permit issued must specify a Dollar General store. In the case of multiple stores, the Dollar General store must be specifically identified. Any change to a facility designated as a Dollar General store would require a re-evaluation of the design flow and the system design, and revised permits would have to be issued. 8. We recommend the installation of a water meter for the Dollar General store.

AFFIRMATIVE ACTION EMPLOYER _'4 ARM Geothermal, Environmental, & Wel I Drilling 8 September 2022 NC Division of Water Resources Attn: Lauren Raup-Plummer 1617 Mail Service Center Raleigh, NC 27699 Re: Family Dollar, Montague RD (ARM Project 220216) Pender County, North Carolina -Additional Information Ms. Raup-Plummer, This report presents the results of additional soil and site testing for the above referenced property in accordance with guidance from NCDEQ August 12, 2022. Specifically, this report addendum is in reference to Section E of that letter. El Saturated hydraulic conductivity (Ksat) values were only provided for depths of 22 to 40 inches and 66 to 84 inches. The Murville Muck series, as described in the "Soil Survey of Pender County, North Carolina", includes a mucky fine sand in the A horizon. The provided engineering design indicates that the existing soils are to remain in situ, and hydraulic conductivities were not provided for the full soil profile. Indications of a shallow groundwater table were noticed throughout the Soil Evaluation and it is unclear whether the values depicted in Table i are representative of the most restrictive soil horizon at the site. Please provide additional information regarding the saturated hydraulic conductivity in the upper 22 inches of the soil profile. Response: The Saturated Hydraulic Conductivity (Ksat) of the A horizon at each previous soil boring profile was tested. The tested depths were noted to be in saturated and unsaturated conditions. The saturated hydraulic conductivity of the unsaturated portion was measured with a compact constant head permeameter from Ksat, INC. Tests and result calculations were conducted in accordance with the User Manual from Ksat, INC. The saturated hydraulic conductivity tests for the saturated portion were conducted using the slug test method. Slug tests were performed utilizing a monitoring well that was constructed utilizing a two-inch PVC screen encased in a four -inch boring. The screen was encased in a gravel pack. The tested layer was isolated using a bentonite grout above the gravel packed screen. Test data was input into AquiferTest version 3.5 from Waterloo Hydrogeologic, INC. The results were analyzed utilizing the Bouwer and Rice method. A test specific data sheet was prepared for each location and is provided in Appendix A. The saturated hydraulic conductivity within the A horizon was noted to range between 0.03 inches per hour and 4.19 inches per hour with a geometric mean of 0.42 inches per hour at a depth of approximately 6 - 14 inches. Results are summarized in Table 1 below. Table 1. Area I Hydraulic Conductivity Results (A Horizon) Location Conductivity (In/Hr) Test / Depth MW 1 -Test 1 4.19 CCHP / 6" MW 2 - Test 1 0.59 CCHP / 8" MW2-Test 2 0.31 Slug /13" MW 2 - Test 3 0.65 Slug / 13" MW 3 - Test 1 0.03 Slug / 14" MW 3 - Test 2 0.39 Slug / 14" Geometric Mean 0.42 Based on this most recent testing, the A horizon appears to be the most limiting. In order to keep with the previous design, the proposed wastewater irrigation field shown shall be modified by removal of the A horizon down to approximately 12 - 14" below the existing soil surface. Once removed, C33 or 2S concrete sand is to be incorporated into the Bh horizon to a depth of 4-6 inches and is to be backfilled to existing grade. Additional C33 or 2S concrete sand fill shall be placed to a depth of approximately 24 inches above existing soil surface. The addition of this fill material is needed to provide positive drainage as well as prevent ponding of surface water and/or wastewater The area will be backfilled with a coarse -grained sand with a C-33 or 2S concrete sand back to existing grade. This sand material will have a saturated conductivity equal to or greater than the Bh horizons. E2. Within the Soil Evaluation, a maximum daily design flow of 200 gallons per day (GPD) is provided based on the preliminary water balance data with a note that the maximum daily design flow may be limited by nutrient loading rather than hydraulic loading. The loading rated analysis section indicates that phosphorus removal is the limiting design criteria and provides a maximum loading rate of 420 GPD - this is reflected in the Daily Design Flow calculation in Appendix B. The engineering design for this application uses a daily design flow of 260 GPD. It is unclear what the basis is for the 200 GPD recommend in the Soil Evaluation, and whether the proposed engineering design daily flow of 260 GPD is attainable for the current site conditions. Please address the inconsistencies between the daily design flow requirements and provide additional information as needed. Response The discrepancy between daily design flow values comes from guidance from the NC Onsite Water Protection Branch detailing reduced daily design flow values for Family Dollar Stores based on square footage. According to this guidance, the 200 GPD value applies to stores with a retail square footage up to 8,000 square feet. We were unaware that the intended retail square footage was to be greater than 8,000 square feet. It is understood that the daily design flow will be 260 GPD. A copy of this guidance is provided. Based on the realistic yield expectation for the Murville series. The daily design flow of 260 GPD was noted to be well below the 420 GPD, needed to be nutrient limiting and thus does not appear to be nutrient limiting. �" Should you have any questions or concerns p s8` do,L'notesita (910)270-2919.

Trees and permanent structures not located within the work area shall be removed only as directed. B. PROTECTION OF PRIVATE PROPERTY: The Contractor shall provide protection for privately owned trees and shrubs bordering the work area and shall take full responsibility for any damage that does occur. 1.04 CLEARING AND GRUBBING Clearing and grubbing shall be performed in areas indicated and where required for construction. It shall include the complete removal and disposal of all brush, weed, timber, stumps, rubbish, and all other obstructions. All such material shall be removed to a depth of at least one foot below finished grade. In clearing and grubbing areas where excavation is done, all timber, roots, or stumps removed that are exposed by said excavation shall be removed to a depth of two feet below the excavated surface. Clearing and grubbing operations shall be completed sufficiently in advance of grading operations as may be necessary to prevent any of the debris from the clearing and grubbing operations from interfering with the excavation, embankment, or other operations. The work shall be performed in a manner that will cause a minimum of soil erosion. The Contractor shall perform such erosion control work, temporary or permanent, as may be necessary in order to satisfactorily minimize erosion resulting from clearing and grubbing operations. 1.05 DISPOSAL OF CLEARED AND GRUBBED MATERIAL All refuse from the clearing and grubbing operation shall be disposed of either by burning or removal to a dump area that is approved by the Owner. The Contractor shall obtain a burning Family Dollar WWTF - Currie TS-2 Technical Specifications permit from the fire chief having jurisdiction before any burning is started. Burning, if approved, shall be done in such manner that it does not create hazards such as damage to existing structures, trees and vegetation, interference with traffic and construction in progress, or create nuisance to adjacent property owners. When the construction site is outside the city limits and burning is required, proper permits shall be obtained from the town, county or state officials. All disposals by burning shall be kept under constant supervision until all fires have been extinguished and all burning shall comply with all state and local laws relative to the building of fires. Family Dollar WWTF - Currie TS-3 Technical Specifications SECTION 02300 – EARTHWORK 1.01 GENERAL The work in this Section covers the furnishing of all labor, equipment and materials required to complete all excavation, backfilling, sheeting and shoring, dewatering, compacting, and disposal of excavated material to complete the work as indicated on the drawings and specified herein, and as directed by the Engineer.

Subsurface investigation, boring plan and logs are included in the Contract Specifications for information purposes only. 1.02 CHARACTER OF EXCAVATED MATERIAL Since soils vary widely within the project area the Contractor shall be responsible to satisfy himself as to the nature of material that will be encountered during the course of the project. The submission of a Proposal shall be conclusive evidence that the Contractor has investigated the site and is satisfied as to the conditions to be encountered, as to the character, quality, and quantities of work to be performed and materials to be furnished, and as to the requirements of the Contract Documents. All excavation shall be unclassified regardless of the material encountered. 1.03 EXISTING UTILITIES Existing underground utilities and structures that are indicated on the drawings shall be located by the Contractor before any earthwork operations are begun in order to avoid conflicts and costly repairs of any utility. If utilities are to remain in place, adequate means of protection shall be provided during earthwork operations. Where unforeseen or incorrectly located utilities are encountered during excavation, the Engineer or his representative must be informed immediately for conflict resolution. Where it is impossible to avoid conflict with existing utilities, the new construction shall be performed in a manner that will cause the least amount of interruption to the existing facility. The Contractor shall cooperate with the Owner, and public and private utility companies in keeping their respective services and facilities in operation. 1.04 PROTECTION OF PERSONS AND PROPERTY The Contractor shall barricade open excavations occurring as part of this work and post with warnings. Protect structures, utilities, sidewalks, pavements and other facilities from damage caused by settlement, lateral movement, undermining, washout and other hazards created by earthwork operations. Any settlement in backfill, fill, or in structures built over the backfill or fill, which may occur within the one year warranty period in the General Conditions will be considered to be caused by improper compaction methods and shall be corrected at the Contractor's sole expense. Also, any structures damaged by settlement shall be restored to their original condition by the Contractor at his sole expense. Family Dollar WWTF - Currie TS-4 Technical Specifications 1.05 DEWATERING Pumping equipment shall be provided and employed to prevent water and subsurface or groundwater from accumulating or flowing into excavations and from flooding the project site and surrounding area. Do not allow water to accumulate in excavations. Remove water to prevent the softening of foundation bottoms, undercutting footings, and soil changes detrimental to stability of subgrades and foundations. Provide and maintain pumps, sumps, suction and discharge lines, and other dewatering system components necessary to convey water away from the excavations. The disposal of conveyed water shall be diverted in such a manner that the natural drainage of the area shall not be disturbed. All gutters, drains, sewers, storm drains and culverts shall be kept clean from surface drainage. The cost(s) of providing dewatering system(s) are to be incidental to the construction of the storage basin improvements and shall be included in the lump sum bid. Dewatering operations shall be in accordance with the Sedimentation Pollution Control Act. 1.06 SOIL EROSION The Contractor shall be responsible for prevention of soil erosion during construction to the maximum extent possible to comply with all applicable North Carolina soil erosion laws and regulations. The Engineer may limit the surface area or erodible earth material exposed by clearing and grubbing, excavation or borrow and fill operations; and to require immediate installation of temporary pollution control measures to prevent contamination of adjacent streams or other watercourses, lakes, or ponds. The Engineer’s authority to order such work will be used for situations not foreseen by the plans and specifications. In case of repeated failures on the part of the Contractor to control erosion/pollution, right is reserved by the Engineer to employ outside assistance to provide the necessary corrective measures. Such incurred costs, plus related engineering costs, will be charged to the Contractor and appropriate deductions made from the Contractor’s progress payments. The erosion control features installed by the Contractor will be acceptably maintained by the Contractor during the time that construction work is being done. Pollutants such as fuels, lubricants, bitumens, raw sewage and other harmful materials will not be discharged into or near rivers, streams, and impoundments or into natural or man-made channels leading thereto. All such materials shall be disposed of in accordance with applicable regulations. 1.07 SHEETING, SHORING, AND BRACING The Contractor shall provide sheeting and bracing where necessary to prevent movement of the walls of excavation and/or to comply with regulations of the North Carolina Department of Labor and the Occupational Safety and Health (OSHA) Act of 1970. Failure to adequately sheet and brace the walls of excavations shall be at the Contractor’s risk and the Contractor shall be responsible for any damages to persons, pipelines, equipment, structures, or adjacent property caused by movement of the walls. When sheeting is used, additional width of trench shall be permitted to accommodate the thickness of the sheeting and to obtain the minimum sidewall clearance. Sheeting and Bracing are considered incidental to the construction of the drainage improvements. The costs shall be included in the lump sum Contract Amount for the Contract items requiring the sheeting and bracing for installation. Family Dollar WWTF - Currie TS-5 Technical Specifications 1.08 STRIPPING All vegetation such as brush, heavy sods, heavy growth of grass, decayed vegetable matter, rubbish and any other unsuitable material within the proposed construction site shall be stripped or otherwise removed prior to the placement of fill material. 1.09 EQUIPMENT The Contractor may use any type of earth-moving, compaction and watering equipment that will minimize detrimental impacts to the irrigation area, provided the equipment is in satisfactory condition and is of such capacity that the construction schedule can be maintained as planned by the Contractor and as approved by the Engineer in accordance with the total calendar days or working days scheduled for construction. The Contractor shall furnish, operate and maintain such equipment as is necessary to control uniform density, layers, section and smoothness of grade. 1.10 PREPARATION AND PROTECTION OF THE TOP OF THE SUBGRADE After all drains, structures, ducts and other underground appurtenances have been completed, the subgrade shall be compacted to the depth specified. Any irregularities or depressions that develop under rolling shall be corrected by loosening the material at these places and adding, removing, or replacing material until the surface is smooth and uniform. Any portion of the area which is not accessible to a roller shall be compacted to the required density by approved mechanical tampers. The material shall be sprinkled with water during rolling or tamping as directed by the Engineer. All soft and yielding material that will not readily compact when rolled or tamped shall be removed as directed by the Engineer and replace with suitable material at the Contractor’s expense. After grading operations are complete, all loose stones larger than 2” in their greatest dimension shall be removed from the surface of all proposed graded areas and disposed of as directed by the Engineer. At all times, the subgrade shall be kept in such condition that it will drain readily and effectively. In handling materials, tools and equipment, the Contractor shall protect the subgrade from damage and shall take other precautions as needed. In no case will vehicles be allowed to travel in a single track. If ruts are formed, the subgrade shall be reshaped and rolled. Storage or stockpiling of materials on top of the subgrade will not be permitted. Until the subgrade has been checked and approved, no subbase, base, surface course or pavement shall be laid thereon. 1.11 TOPSOILING It is the intent of these specifications that all graded areas be constructed to the lines and grades as shown on the plans and within the tolerances specified herein. It is also the intent of these specifications that all graded areas be established with a satisfactory turf as set forth in Section 3 – SEEDING AND TURFING. The Contractor may at his discretion utilize topsoil retained from the grading operations to provide a proper seedbed for the turfing operations. In embankment areas, the Contractor may, at his discretion, utilize topsoil to complete the top 4-inchs of the embankment outside of the earthen liner area. Regardless of whether or not topsoil is utilized by the Contractor, he shall be required to establish a satisfactory turf as specified in these documents. Family Dollar WWTF - Currie TS-6 Technical Specifications 1.12 UNSUITABLE EXCAVATED MATERIAL UNDER STRUCTURES AND YARD PIPING If material found at the specified depths of excavation below the elevation is not suitable to provide adequate foundation of the structure or pipe, a further depth shall be excavated and filled with suitable material only if authorized by the Engineer. If the excavation for the structure is below the grade as noted on the plans through Contractor error or by improper drainage or dewatering softens the subgrade and addition excavation is required, this removal and replacement of material will not be measured for payment. Family Dollar WWTF - Currie TS-7 Technical Specifications SECTION 02320 – SEEDING AND TURFING 1.01 SCOPE This section shall include the furnishing of all labor, materials, equipment and incidental items to seed and establish a turf on all areas disturbed by the pipe laying operations or any other earth disturbing operations. All materials shall be of the best commercial quality available for the purposes specified. Work consists of soil preparation, liming, fertilizing and seedbed preparation, grass seeding, and mulching, complete, for all areas within limits of grading in accord with specifications and applicable drawings. 1.02 GRADING Rough grading shall be done as soon as all excavation required in the area has been backfilled. The necessary earthwork shall be accomplished to bring the existing ground to the desired finish elevations as shown on the Contract Drawings or otherwise directed. Fine grading shall consist of shaping the final contours for drainage and removing all large rock, clumps of earth and waste construction material. It shall also include thorough loosening of the soil to a depth of 6-inches by plowing, discing, harrowing or other approved methods until the area is acceptable as suitable for subsequent seeding operations. 1.03 TOPSOIL Areas specifically noted on the Contract Drawings shall receive a layer of topsoil of the thickness noted and as specified herein. After the subgrade has been fine graded to the satisfaction of the Engineer, topsoil shall be spread over the area to a uniform depth and density. The soil shall be uniformly compacted by a light roller to a depth not less than 4-inches, unless other depths are shown on the Plans. When finished, the surface shall conform to the finished grade shown or required and shall have a smooth pulverized surface at the time of seeding. Any irregularities shall be corrected before the seed is placed. Any settlement or displacement of the topsoil shall be restored to the established lines and grades at the Contractor’s own expense. Topsoil removed from the excavations, which is approved by the Engineer for use, shall be placed in the locations and to the depth shown, specified or directed. In the event the topsoil removed during excavation is unsatisfactory or is inadequate to cover the requested areas, the Contractor shall furnish the required quantity of satisfactory topsoil from approved sources off the site. Topsoil furnished from areas off the site shall be a friable clay loam free from stones, roots, sticks, and other foreign substances. Such topsoil shall pass a ¼-inch screen. Topsoil shall not be delivered or placed in a frozen or muddy condition. 1.04 LIME The quality of lime and all operations in connection with furnishing this material shall comply with the requirements of the North Carolina Department of Agriculture. During the handling and storing, the lime shall be cared for in such a manner that it will be protected against hardening and caking. Any hardened or caked lime shall be pulverized to its original condition before being used. No lime or seed shall be applied when the wind is strong or when the soil is extremely wet or otherwise unworkable. No rolling shall be done if precipitation after seeding should make the operation detrimental to the seedbed. Family Dollar WWTF - Currie TS-8 Technical Specifications Liming shall be done immediately after grading has reached the final “smoothing” stage, even though actual seeding may not be done until several months later. Lime shall be used at 2 tons per acre and shall be spread evenly by means of approved mechanical spreaders or distributors. When lime is distributed by commercial liming dealers, sales slips showing the tonnage delivered shall be filed with the Engineer and shall show the full tonnage required for the acres treated. Lime shall be incorporated in the top 2 to 3 inches of soil by harrowing, disking, or other approved means. Lime shall be agriculture grade ground dolomitic limestone. It shall contain not less than 85 percent of the calcium and magnesium carbonates and shall be of such fineness that at least 90 percent will pass a Number 10 sieve and at least 50 percent will pass a Number 100 sieve. 1.06 SEEDING The quality of seed and all operations in connection with the furnishing of this material shall comply with the requirements of the North Carolina Seed Law and regulations adopted by the North Carolina Department of Agriculture. Seed shall have been approved by the North Carolina Department of Agriculture or any agency approved by the Engineer before being sown, and no seed will be accepted with a date of test more than eight months prior to the date of sowing. Such testing, however, will not relieve the Contractor from responsibility of furnishing and sowing seed that meets these specifications at the time of sowing. When a low percentage of germination causes the quality of the seed to fall below the minimum pure live seed specified, the Contractor may elect, subject to the approval of the Engineer, to increase the rate of application sufficiently to obtain the minimum pure live seed content specified, provided that such an increase in the rate of application does not cause the quantity of noxious weed seed per acre or square yard, as the case may be, to exceed the quantity that would be allowable at the regular rate of application. During handling and storing, the seed shall be cared for in such a manner that it will be protected from damage by heat, moisture, rodents, or other causes. Immediately following preparation of the seedbed, the seed shall be uniformly applied by a mechanical spreader. The seed shall be raked lightly into the surface and rolled with a light hand lawn roller weighing not more than 100 pounds per foot of width. Seeded areas shall be sprinkled with a fine spray in such a manner as not to wash out the seed. Seeding shall be done on a “calm” day and only with the approval of the Engineer or his representative. The Contractor shall water as necessary and keep all seeded areas in good condition, and re-seed if and when necessary, until a smooth and uniform grassed area is established over the entire area seeded and shall maintain these areas in an approved condition until final acceptance of the Contract. On slopes, the Contractor shall provide against washouts by an approved method. Any washouts which occur shall be re-graded and re-seeded until a grass area is established. 1.07 MULCHING Straw mulch shall be threshed plant residue of oats, wheat, rye, free from matured seed of obnoxious weeds or other species that would grow and be detrimental to the specified grass. It shall be spread uniformly at a rate of two (2) tons per acre in a continuous blanket over the areas specified not later than two (2) days after seeding. Thickness of the covering shall be adequate to hold the soil but sufficiently loose and open to favor the development of the grass. Mulch shall be held in place by applying a sufficient amount of asphalt or other approved binding material to assure that the mulch is properly held in place. The rate and method of application of binding material shall meet the approval of the Engineer or his representative. Where binding Family Dollar WWTF - Currie TS-9 Technical Specifications material is not applied directly with the mulch, it shall be applied immediately following the mulch application. An extra application may be necessary in the bottom of drainage swales to prevent erosion. 1.08 MAINTENANCE Begin maintenance immediately after each portion of grass is planted and continue for eight (8) weeks after all grass planting is completed. The Contractor shall be responsible for maintenance, protection, repairing and resulting reseeding and refertilization at the end of the eight (8) week grass maintenance period. No direct payment will be made for any maintenance.

Tests have been performed both in test centers and in the field. These include testing performed by outside companies or agencies (third-party); contract testing performed by Orenco distributors (second-party); and Orenco’s own testing (first- party). More than 1000 data points have been collected. This performance summary documents the performance of AdvanTex Treatment Systems relative to nutrient reduction . . . specifically, reductions in Total Nitrogen (TN), Ammonia (NH3), and Total Phosphorous (TP). The results show that AdvanTex systems easily meet advanced treatment standards for nitrogen and total phosphorous. About System Configurations As shown in the illustrations on the right, AdvanTex systems can be configured in several ways depending on the degree of total nitrogen reduction required. In Mode 1, filtrate from the AdvanTex pod is recirculated to the secondary chamber of the septic tank. In Mode 3, the filtrate is recirculated to the primary chamber, where the environment favors further denitrification. In Combo mode, the filtrate is recirculated to both chambers, in controlled proportions. In Virginia, North Carolina, and Rhode Island, some of the systems tested in Mode 1 in- corporated two tanks: a primary tank and a recirculation tank. In the primary tank, sludge and scum are separated from liquid effluent, which then flows into a separate recircula- tion tank, into which the AdvanTex filtrate is recirculated. About the Results The table below summarizes effluent testing results for Total Nitrogen, Ammonia, and Total Phosphorous, both from test center programs and field testing programs. The pages that follow provide more specific results of these testing programs. For ease of compari- son, we have also included information about the circumstances of each test.

Tests have been performed both in test centers and in the field. These include testing performed by outside companies or agencies (third-par- ty); contract testing performed by Orenco distributors (second-party); and Orenco’s own testing (first-party). This performance summary documents the performance of AdvanTex Treatment Systems relative to reduction of BOD5, TSS, and Fecal Coliform. The results show that AdvanTex systems easily meet advanced treatment standards for these parameters. About System Configurations As shown in the illustrations on the right, AdvanTex systems can be configured in different ways, depending on the degree of total nitrogen required. In Mode 1 (top left illus), filtrate from the AdvanTex pod is recirculated to the secondary chamber of the septic tank. In Mode 3 (top right illus), filtrate is recirculated to the primary chamber, where the environment favors further nitrogen reduction. See AdvanTex Performance Summary — Nutrient Reduction for TN, NH3, and TP results (AHO-ATX-PERF-TN-1). In the Combo Mode (center illus), filtrate from the AdvanTex pod is recirculated to both chambers. There is also a Mode 1 configuration (bottom illus) that uses a prima- ry tank and a recirculation tank. In the primary tank, sludge and scum are separated from liquid effluent, which then flows into a separate recirculation tank, into which the AdvanTex filtrate is recirculated.

It requires installation inside a pump or gravity discharge basin or in a separate tank following an AdvanTex Treatment System. AXUV units can be also be mounted in the AX20-RT Treatment System. General Treated effluent flows by gravity through the contact chamber and around the UV lamp where it is disinfected in a 360-degree contact zone. The unit uses no chemicals and has no moving parts. It requires annual cleaning and lamp replacement. In side-by-side NSF® testing, the AXUV reduced bacteria by 99.999% (5 logs), meeting or exceeding the performance of other residential UV disinfection units. For protection, the power ballast and lamp current sensor for the AXUV disinfection unit are housed in either an Orenco MVP™ digital control panel or a VeriComm™ remote telemetry control panel. These panels prevent discharge of non-disinfected effluent due to lamp failure or control panel failure. The current sensor monitors lamp function and, in the event of lamp failure, the discharge pump is automatically dis- abled. With MVP-equipped systems, an audible and visible alarm is activated. With VeriComm-equipped systems, an e-mail alert is sent to the Service Provider. Features/Specifications • UL-recognized for US and Canada • Bacteria reduced by 99.999% (5 logs) • Flow path designed for maximum contact time between effluent and lamp • Teflon sleeve to protect lamp and minimize buildup and service intervals • Quick-disconnect fitting for easy inspection and unit cleaning • Power ballast and lamp current sensor housed in a control panel (not a tank or riser) to minimize corrosion and failure due to envi- ronmental exposure • Components designed to work together with AdvanTex Treatment Systems — no piecemeal disinfection assemblies and wiring Standard Model AXUV-125/31 Product Code Diagram 31125AXUV Power cord length: Blank = 25 ft (7.62 m) 50 = 50 ft (15.2 m) --/ AdvanTex™ UV disinfection unit Lamp length: 31 = 31 in.

For large systems or systems with a BOD > 30 mg/l automation of maintenance is essential. Inspection and maintenance should be performed every six months. ROUTINE AND PREVENTATIVE MAINTENANCE o Clean the filter cartridge. This may be done with a pressure hose. Vortex screen filter cartridge should be cleaned from the outside inwards, while the discs in the disc filter cartridge should be separated and then cleaned. If bacteria buildup is a problem, we advise first trying lye, and if the problem persists, soak the filter cartridge in a chlorine bath - a mixture of 50% bleach and 50% water. o Open the field flush valve and flush the field for 3-5 minutes by activating the pump in “manual” position. Close the flush valve. On automatic solenoid valves the manual bleed lever should always be in the closed position and the dial on top should be free spinning. This allows it to open when pulsed electrically. Clockwise rotation closes valve. o With the pump in the “manual” position, check the pressure in the drip field by using a pressure gauge on the Schrader valve located on the air vents and by reading the pressure gauge located in the Wasteflow Headworks box. The pressure should be the same as shown on the initial installation records. On systems with manual flush valves, close the field flush valve completely and then open the valve slightly until there is a 1-2 psi drop or design pressure is reached. This will allow the field to drain after each dose to prevent the manifold lines from freezing. o Remove the lids on the vacuum breaker and check for proper operation. If water is seen leaking from the top of the vacuum breaker, remove the cap of the vacuum breaker and press down on the ball to allow any debris to be flushed out. Be careful not to come in contact with the effluent. o Turn off the pump and reset the controller for auto mode. o Periodically remove and clean the air vents, field flush and filter flush valves. o Visually check and report the condition of the drip field, including any noticeable wetness. o Treatment and distribution tanks are to be inspected routinely and maintained when necessary in accordance with their approvals. o Record the elapsed time meter, pump counter, override counter, high-level alarm and power failures. This information can be obtained from the controller. 26 GEOFLOW Inc. 800-828-3388/415-927-6000 www.geoflow.com A drip dispersal system has been installed on your property for the subsurface dispersal of the effluent from your home. The drip dispersal system consists of a series of ½” diameter drip tubing installed at a shallow depth of 6-10” below the ground surface. It is designed to effectively disperse the treated effluent in the ground with a combination of soil absorption and plant uptake. Your drip dispersal system will function for many years with only minimal maintenance being required, provided the following recommendations are followed: o Establish landscaping (preferably a grass cover) immediately. This will stabilize the soil and allow for the grass to take up the water. o Do not discharge sump pumps, footing drains or other sources of clear water to the system, except for the effluent discharge from your treatment system. o Maintain all plumbing fixtures to prevent excess water from entering the dispersal system. o Do not drive cars, trucks or other heavy equipment over the drip dispersal field. This can damage the drip components or the soil and cause the system to malfunction. Lawn mowers, rubber wheeled garden tractors and light equipment can be driven over the drip field. o Do not drive tent stakes, golf putting holes, croquet hoops etc., into the dispersal field o Contact your service company if your high water alarm should sound. The pump chamber is sized to allow additional storage after the high water alarm sounds but you should refrain from excessive water usage (i.e., laundry) until the system has been checked. o After a temporary shut down due to a vacation or other reason, the treatment plant ahead of the drip field filter initially may not function effectively, resulting in the filter blocking. Refer to maintenance guidelines above to clean the filter. Contact your service company if you notice any areas of excessive wetness in the field. In most cases, this is usually caused by a loose fitting or a nicked dripline and can be easily repaired. Note: There may be some initial wetness over the dripline following the system’s installation. This should cease once the ground has settled and a grass cover is established HOME OWNERS GUIDE FOR CARE AND MAINTENANCE OF GEOFLOW DRIP DISPERSAL FIELD GEOFLOW Inc. 800-828-3388/415-927-6000 www.geoflow.com 27 SITE INSPECTION LIST: Contractor Site Address _____________________________________________________ Date _____________________________________________________ Site observations 1 Is dripfield located at the lowest point in the site where all waters may pond? 2 Is there any water coming in from neighbors?

During other times the water level in the pump chamber is at a normal level Possible cause: Peak water usage (frequently laundry day) is causing a temporary high water condition to occur. Remedy: Set timer to activate the pump more frequently. Be sure to not exceed the total design flow. To avoid this, reduce the duration of each dose. Remedy: Provide a larger pump tank to accommodate the peak flow periods. Symptom: High water alarm activates during or shortly after periods of heavy rainfall. Possible cause: Infiltration of ground/surface water into system. Remedy: Identify sources of infiltration, such as tank seams, pipe connections, risers, etc. Repair as required. Symptom: High water alarm activates intermittently, including times when it is not raining or when laundry is not being done. Possible cause: A toilet or other plumbing fixture may be leaking sporadically but not continuously. Check water meter readings for 1-2 weeks to determine if water usage is unusually high for the number of occupants and their lifestyle. Also determine if water usage is within design range. Remedy: Identify and repair fixture. Symptom: High water alarm activates continuously on a new installation (less than 3 months of operation). Inspection of the filter indicates it is plugged with a gray colored growth. Water usage is normal. Possible cause: Slow start-up of treatment plant resulting in the presence of nutrient in the effluent sufficient to cause a biological growth on the filter. This is typical of lightly loaded treatment plants that receive a high percentage of gray water (i.e., from showers and laundry), Remedy: Remove and clean filter cartridge in a bleach solution. Add a gallon of household bleach to pump tank to oxidize organics. Contact treatment plant manufacturer for advice on speeding up the treatment process possibly by “seeding” the plant with fresh activated sludge from another treatment plant. Symptom: Water surfaces continuously at one or more isolated spots, each one foot or more in diameter. Possible cause: Damaged drip line or a loose connection is allowing water be discharged under pressure and therefore at a much greater volume than intended. Remedy: Dig up drip line. Activate pump and locate leak. Repair as required. Possible cause: If water is at base of slope, can be caused by low-head drainage. Remedy: Install check valves and airvents in the manifolds to redistribute water in the system after pump is turned off. This is not advised for freezing climates where manifold drainage is required. Symptom: A portion of the drip field closest to the feed manifold is saturated while the rest of the field is dry. TROUBLE SHOOTING GUIDE: GEOFLOW Inc. 800-828-3388/415-927-6000 www.geoflow.com 29 Possible cause: Insufficient pump pressure. A pressure check at the return manifold indicates pressure of less than 10 psi. Remedy: Check filter and pump intake to insure they are not plugged. If they are, clean as require. Remedy: Leaks in the system may be resulting in loss of pressure. Check for water leaks in connections and fittings or wet spots in the field. Also check air vents to insure they are closing properly. Repair as necessary. Remedy: Pump is worn or improperly sized. Pressure at feed manifold is less than 15 psi. Verify pressure requirements of system and provide a new or larger pump. As an alternate approach, the drip field may need to be divided into two or more zones. Possible cause: The duration of each dose is of insufficient length to allow the drip field to become pressurized before the pump shuts off (or runs for only a brief time before turning off). Remedy: Increase the pump run time and decrease the frequency of doses. Always calculate (or observe during field operation) how long the system takes to fully pressurize and add this time to the design dosing duration. Symptom: High water alarm begins to activate continuously after a long period (1-2 years) of normal operation. Inspection of the filter indicates it is plugged with a heavy accumulation of sludge. Possible cause: A buildup of solids in the pump tank due to carryover from the treatment plant. Remedy: Replace the filter cartridge with a clean cartridge. Check the pump tank and if an accumulation of solids is noted, pump the solids out of the pump tank. Also, check the operation of the treatment plant to insure it is operating properly. Symptom: Water surfaces at several spots in drip field during dosing periods. Installation is recent, less than 6 months of usage and the soil is a moderate to heavy clay. Possibly, the installation was completed using a non-vibratory plow. Possible cause: Smearing of the soil may have occurred during installation of drip line. Also, the “cut” resulting from the installation allows an easy path for the water to surface during dosing. Remedy: In most cases the sod will compact naturally around the drip line and the surfacing will diminish and ultimately cease. To help, reduce the duration of each dose and increase the number of doses/day. Also, it will help to seed the area to encourage the development of a good root zone. Symptom: Entire area of drip field is wet, soft and spongy. It appears to be totally saturated with water. Situation occurs during dry season when there is little rainfall. Possible cause: Water being discharged to drip field exceeds design. Excess water may be a result of infiltration, plumbing leaks or excessive water usage. Remedy: Check water meter, elapsed time meter, pump counter, override counter or high level alarm counter to determine if water usage is in excess of design. Check for leaks or infiltration. Repair leaks as required. Reduce water usage by installing water saving fixture. Remedy: If water usage cannot be reduced, enlarge drip field as required. Possible cause: Area of drip field was inadequately sized and is too small. Remedy: Provide additional soil analysis to verify sizing and enlarge as required. 30 GEOFLOW Inc. 800-828-3388/415-927-6000 www.geoflow.com Valve Troubleshooting Symptom: Valve will not open manually Check water supply and any possible master or gate valves to insure they are open. Check that the valve is installed with the arrow pointing in the downstream direction Check that the flow control is fully open, counterclockwise. Turn off the water supply. Remove the solenoid and check for debris blocking the exhaust port. Turn off the water supply. Remove the cover. Inspect the diaphragm for damage and replace if necessary. Symptom: Valve will not open electrically Check voltage at controller for 24 VAC station. Check voltage across the solenoid lead wires for minimum 21 VAC. Make sure handle on top of valve is free spinning. Not all the way open or all the way closed. If the valve still does not operate, electrically replace the solenoid. Symptom: Valve will not close Insure the manual bleed lever is in the closed position. Check for leaks around the flow control, solenoid or between valve cover and body. Turn off the water supply. Remove the solenoid and check for debris or damage to the exhaust port. Turn off the water supply. Remove valve cover and inspect for debris under diaphragm or debris in diaphragm ports. Symptom: Slow leak Check for dirt or gravel embedded in the diaphragm seat. Check actuator and exhaust fitting for proper seating.

With the dripline hidden about six inches below ground, effluent is distributed slowly and uniformly, reducing ponding, even in difficult soils and hilly terrain. WASTEFLOW is built to last. It is guaranteed to be trouble- free from root intrusion with built-in nano-ROOTGUARD® protection, and the dripline wall is protected from organic growth with the Geoshield lining. WASTEFLOW provides uniform distribution. The emitters have a Coefficient of variation of less than .05. Different flow rates, dripline diameters and emitter spacings can be special ordered. Use 600 series compression adapters or lockslip fittings to connect the dripline to PVC pipe. nano-ROOTGUARD® Protection WASTEFLOW dripline features patented nano-ROOTGUARD technology to prevent roots from clogging the emission points. The pre-emergent, Treflan®, is bound into WASTEFLOW emitters when they are molded to divert roots from growing into the emitter outlet. The system is guaranteed against root intrusion for 15 years. AnTi BAcTeRiAl Protection Geoshield® is incorporated into the inner lining and emitters of WASTEFLOW dripline to prevent bacteria from growing on the walls of the tubing and emitters. It eliminates the need to scour the tubing. It is a tin based formula that defeats the energy system of microbial cells. This means smaller pumps or larger zones can be used with WASTEFLOW dripline than unprotected dripline. Pc vs. clASSic Geoflow, Inc. offers WASTEFLOW dripline in both pressure compensating (WASTEFLOW PC) and non-compensating (WASTEFLOW Classic) models. We recommend that WASTEFLOW PC be used when the advantages are of substantial economic value. a) Very long runs. b) Steep slopes. Systems should be designed for the dripline lateral to follow the contour. If this is possible, the extra cost of pressure regulators required for WASTEFLOW Classic would likely be less than the incremental cost of WASTEFLOW PC. c) Rolling terrain. If the difference in height from trough to peak exceeds six feet then WASTEFLOW PC should be used. Vacuum relief valves must be placed at the top of each rise. WASTEFLOW PC and WASTEFLOW Classic can be interchanged to meet filter and zone flow requirements.

It is installed between the pump and the field to filter out fine particles from entering the treatment field, and to flush fine particles that may collect in the dripfield. recommended for maximum flow rate of 30gallons per minute and 600 gallons per day. Process During a dosing cycle, the wastewater exits the pump cham- ber and enters the inlet fitting of the Sporty Headworks. It passes through the filter before exiting the box and going to the dripfield zone that is open. Both the field flush valve and zone flush valves are closed at this time. The water enters back into the Headworks through the return line, goes past the point to measure pressure and stops at the field flush valve. During a field flush cycle, water enters the Headworks as above, the filter flush valve remains closed, but the field flush valve opens to allow water to circulate through the dripfield and return back into the return fitting of the headworks, past the pressure gage and through the field flush valve at an in- creased velocity than during normal dosing. The water passes through the field flush valve and down the flush line in the headworks to exit the headworks for return to the pump tank or pretreatment tank. When filter flushing, the filter valve opens and the field flush valve is closed. While water passes through the filter to the field, part of the water is directed to the base of the filter, pushing solids down the screen, out of the filter, through the open filter flush valve, into the flush line in the ultra head- works to exit the headworks for return to the pump tank or pretreatment tank.

The true union provides easy access for inline installation and servicing. The true union ball check is designed for quick positive sealing with minimum turbulence, low restriction, and efficient fluid transfer. It can be installed vertically or horizontally. System pressure will unseat the ball, allowing flow. Backflow or head pressure of 30” or 1 to 2 psi will seat the ball and stop back fl ow. Each check valve ships with female thread and socket adapters. This valve is manufactured 100% from thermolastic materials, making is less suseptable to corrosion.

Tel 415-927-6000 / 800-828-3388 Fax 415-927-0120 www.geoflow.com INSTALLATION, OPERATION & MAINTENANCE Systems should always be depressurized and drained prior to installing or maintaining your True Union Ball Check Valves. Temperature effect on piping systems should always be considered when the systems are initially designed. Piping systems must be designed and supported to prevent excess mechanical loading on valve equipment due to system misalignment, weight, shock, vibration, and the effects of thermal expansion and contraction. Because PVC and CPVC plastic products become brittle below 40ºF, Geoflow recommends caution in their installation and use below this temperature. Due to differential thermal expansion rates between metal and plastic, transmittal of pipe vibration, and pipe loading forces DIRECT INSTALLATION OF METAL PIPE INTO PLASTIC CONNECTIONS IS NOT RECOMMENDED. Wherever installation of plastic valves into metal piping systems is necessary, it is recommended that at least 10 pipe diameter in length of plastic pipe be installed upstream and downstream of the plastic valve to compensate for the factors mentioned above. SOCKET CONNECTION: Socket end connections are manufactured to ASTM D2467 (PVC) and F-439 (CPVC). Solvent cementing of socket end connections to pipe should be performed per ASTM specifications D2855-87. Cut pipe square. Chamfer and deburr pipe. Surfaces must be cleaned and free of moisture, oil, dirt and other foreign material. Remove Union-nuts and end connectors from valve body. Slide Union-nuts, with threads facing valve, onto pipe to which the end connector is to be cemented. Apply primer to inside socket surface of end connector. Never allow primer or cement to contact valve ball or end connector o-ring sealing surfaces, as leaking may result. Use a scrubbing motion. Repeat applications may be necessary to soften the surface of the socket. Next, liberally apply primer to the male end of the pipe to the length of the socket depth. Again apply to the socket, and without delay apply cement to the pipe while the surface is still wet with primer. Next apply cement lightly, but uniformly to the inside of the socket. Apply a second coat of cement to the pipe, and assemble end connector to the pipe, rotating the end connector 1/4 turn in one direction as it is slipped to full depth on to the pipe. The end connector should be held in position for approx. 30 seconds to allow the connection to “set”. After assembly wipe off excess cement. Follow cement manufacturers guidelines for proper “cure-time”, based on the pipe size that you are joining. THREADED CONNECTION: Threaded end connections are manufactured to ASTM specifications D2464. F437 and ANSI B1.20.1. Due to the variable quality and tolerances of plastic male threaded nipples, Colonial no longer recommends the use of PTFE (Teflon®) tape. We recommend using the following thread sealant: IPS WELD-ON All Seal™. To provide a leak proof joint, the pipe should be threaded into the end connection “hand tight”. A strap wrench may be used to tighten the joint an additional 1/2 turn past hand tight. Tightening beyond this point may induce excessive stress that could cause failure. • • • • • • Air Vent / Vacuum Relief Valve Product Sheets-2011 AirVentVacuumRelief(ir) 11E05.indd Air Vent / Vacuum Relief Valve Geoflow, Inc. Tel 415-927-6000 / 800-828-3388 Fax 415-927-0120 www.geoflow.com Description Air release occurs when air escape the system at startup and vacuum relief allows air to enter during shutdown. The air vent vacuum breakers are installed at the highest points in the drip field to keep soil from being sucked into the emitters due to back siphoning and back pressure. This is an absolute necessity with underground drip systems. They are also used for proper drainage of the supply and return manifolds. Use one on the high point of the supply manifold and one on the high point of the return manifold and any high points of the system. Features Geoflow’s new kinetic air vacuum breakers have a twist off cap that is easy to take apart for cleaning. No need to remove the valve to maintain it.

Tel 415-927-6000 / 800-828-3388 Fax 415-927-0120 www.geoflow.com Description Air release occurs when air escape the system at startup and vacuum relief allows air to enter during shutdown. The air vent vacuum breakers are installed at the highest points in the drip field to keep soil from being sucked into the emitters due to back siphoning and back pressure. This is an absolute necessity with underground drip systems. They are also used for proper drainage of the supply and return manifolds. Use one on the high point of the supply manifold and one on the high point of the return manifold and any high points of the system. Features Geoflow’s new kinetic air vacuum breakers have a twist off cap that is easy to take apart for cleaning. The large clear passageway allows lots of air to flow in and out easily. The elbow cap design is ideal for directing wastewater spray, directing spray downward. With the ball removed, these airvents can easily be used as a flush port. Specification The Air Vacuum Breaker shall provide instant and continuous vacuum relief and non-continuous air relief. Both the body and the ball shall be made of molded plastic. The ball shall be removable for easy cleaning. The air vacuum breaker shall be part number APVBK75L or APVBK100L as supplied by Geoflow, Inc.

Maximum Voltage loss with a valve with a three way Solenoid is 4.8 Volts 3-Way Control Line pressure applied to the control chamber of the valve creates a hydraulic force that moves the valve to the closed position and provides drip tight sealing. Discharging pres- sure from the control chamber to the atmosphere causes the line pressure under the plug to open the valve. 2-Way Internal Control Line pressure enters the control chamber through the in- ternal restriction. The closed solenoid causes pressure to accumulate in the control chamber, thereby shutting the valve. Opening the Solenoid releases more flow from the control chamber than the restriction can allow in. This causes pressure in the control chamber to drop, allowing the valve to open. On/Off Modes [1] Cover Ring The cover ring fastens valve cover to body, stiffening and strengthening the valve body, enabling simple maintenance. A cover ring key is available. [2] Pilot Adaptor The pilot adaptor allows us to connect the mini-pilot valve or the Galit hydraulic relay to the valve body.
