These Regulations place significant operation, maintenance and reporting requirements on those entities that own or operate a wastewater collection system with average daily flows of less than 200,000 gallons per day. These regulations are applicable to your facility. This letter is provided as guidance to assist you in complying with the new reporting and operations and maintenance (O&M) requirements and to advise you that you are subject to system review, inspections and possible enforcement, if the system is not in compliance with the regulation. For your convenience and easy reference, a highlight of these requirements and the following guidance are offered (see enclosed). You may find the regulations using the following web site: http://h2o.enr.state.nc.us/peres/Collection%2OSystems/CollectionSystemsHome.htmi The Asheville Regional Office will be increasing the level of oversight, compliance activities and enforcement relating to collections systems, therefore, we wanted to be sure you are aware of the requirements for these systems.

Project no: 91098 Dear Ms. Thornburg: This letter is in response to your comments for Mr. Aaron Hamlin's non -discharge permit application dated June 17, 1999. All comments have been addressed in the plans, specifications, details, and/or this letter. General: 1. Enclosed is one (1) complete set of the revised engineering drawings and technical specifications as you requested 2. The subject permit is to be issued to Aaron Hamlin The subject lots will remain in Mr. Hamlin's possession and will be rented or leased to third parties. Therefore, an operational agreement will not be included as part of this application package. 3. Revised pump station calculations are enclosed and have been signed and sealed by the North Carolina licensed design engineer, David D. Smith, P.E. Wastewater Flows: 1. Aaron Hamlin is the owner of the Wedgefield Acres Mobile Home Park Wastewater Treatment Plant (NPDES Permit No. NC0062634). Pumping Station Design: 1. A portable engine driven generator will be provided as an alternative power source. 2. The pump specification details provided on Sheet C2 have been amended to provide an audible. high-water alarm in addition to the alarm light specified 3. In this specific pump station design we concur with the Division's suggestion concerning the provision that a high water alarm float be placed at the same elevation level as the lag pump on float As such, the drawings have been revised to reflect this amendment. 4. The proposed pump station will be located outside the 100-year flood limit. As you requested, floatation calculations for the proposed pump station are included in the attached information. 5. As shown in the revised pump station calculations, the system-head/pump curve indicates that each pump operating condition is 25.5 gpm at 16 ft. TDH. The drawings and technical specifications are consistent with the calculations. Telephone: (828)254- 448 Fax: (828) 255-0140 6. The proposed um stationsi has been amended to allow for two 2 c c es r hour. Pr Po pump gn () Y per 7. Stainless steel hardware will not be required within the pumping station wet -well and the pump specification details on Sheet C2 have not been revised 8. A gravel road will be provided as access to the proposed pump station as shown on Sheet Cl. Force Main Design: 1. The force main pipe material required will be Schedule 40 PVC. The technical specification has been included. 2. In accordance with our specifications and design drawings, a minimum of three feet of cover will be maintained along the entire length of proposed gravity sewer and forcemain. 3. The drawings have been revised to reflect the change in slope and pipe length you have requested 4. Standard engineering practice dictates that gravity sewers be designed for a maximum of one-half full flow. However, as you requested, the segment of proposed pipe with the maximum slope (Sta. 15+11 to 15+21, slope 49.00) at the peak flow ever (0.0167 cfs), the pipe will flow at a depth of 0.2730 inch and a velocity of 5.235 fps. Therefore, additional measures for protection of the pipe from high velocities arel not be required 5. The total gravity sewer length is 1,047 LF. A corrected Page 2 of 8 is included 6. No water supply wells are located within minimum separation requirements detailed in Regulation 15A NCAC 2H.0219 (I)(2)(G). However, a note has been added to Sheet Cl regarding these minimum separation requirements. I trust the enclosed information is sufficient for completion of your review. However, if you have any questions, please call.

Additional information is required before we can continue our review. Please address the following items no later than July 16, 1999: General: 1) Please submit a complete set of the revised engineering drawings and technical specifications, in addition to the two copies already submitted for review, to the Division of Water Quality (hereinafter Division). 2) Please clarify whether the permit is to be issued to "Aaron Hamlin," as requested in the submitted application form, or to the "Wedgefield Place Mobile Home Association (hereinafter Association)," as provided for by the submitted operational agreement. Note the following: ♦ An operational agreement is only required if the lots (i.e., mobile homes) to be served by the subject wastewater collection system are to be sold. If ownership of these lots is to be retained by Aaron Hamlin and rented/leased to third parties, an operational agreement is not required at all. ♦ If Aaron Hamlin is to be the Permittee with the intention of transferring ownership of the subject wastewater collection system to the Association at a -later date, a different form of the operational agreement is required. A copy of this form of the operational agreement is included with this letter. P.O. Box 29535, Raleigh, North Carolina 27626-0535 Telephone 919-733-5083 FAX 919-715-6048 An Equal Opportunity Affirmative Action Employer 50% recycled/ 10% post -consumer paper General (continued): ♦ If the Association is to be the Permittee, the Division requires copies of the corporation certificate, as awarded by the State of North Carolina under the Non -Profit Corporation Act, as .well as the bylaws for review. 3) The calculations packet submitted with this application package was not signed/sealed by a North Carolina -licensed professional engineer, as required by the instructions on the submitted application form (i.e., see Required Item c. on Page 6 of 8). Wastewater Flows: 1) Please provide the name of the owner of the Wedgefield Acres Mobile Home Park Wastewater Treatment Plant (NPDES Permit No. NC0062634). Note that, if the names of the owner of this facility and the entity to whom this permit is to be issued differ, Required Item e., as listed on Page 6 of 8 of the application form, should be submitted. If this is the case, please provide a flow acceptance letter that contains, at a minimum, the following information: ♦ The name and permit number of the treatment facility to receive the generated wastewater; ♦ The volume of wastewater to be accepted in gallons per day, and ♦ The name of the project that is to generate the accepted wastewater (i.e., this name should be the same as listed in Section I. 4. on Page 1 of 8 of the submitted application form). Pumniniz Station Design: 1) The Division understands that relief is being requested with respect to the pumping station power reliability requirements, as allowed for by Regulation 15A NCAC 2H .0219 (h) (3) (D). Note that some additional information is required before a variance recommendation may be given. Please review the aforementioned rule, and ensure that the system design complies with all three criteria listed therein. In addition, the Division recommends that a three-year history of power reliability for the Wedgefield Place Mobile Home Park, as certified by the local power supplier, be submitted as additional evidence that enough storage time is provided in the wet well of the proposed pumping station as currently designed. Finally, in light of the recent enforcement guidelines affecting collection system and sanitary sewer overflows, please revisit the design approach to this issue. 2) The pump specification details provided on Sheet C2 of the drawings shows that an alarm light is to be installed on the proposed pumping station control panel. Note that, per Regulation 15A NCAC 2H .0219 (h) (5), all pumping stations are required to have audible high-water alarms as well. Please amend the -drawings and/or specifications accordingly. Pumping Station Design (continued): 3) The Division suggests placing the high water alarm float at the same elevation level or below the lag pump on float in the, pumping station wet well. This setting will indicate a failure of the lead pump while the lag. pump is still available. Please consider amending the proposed pumping station design to provide this additional guarantee against failure. 4) Please submit flotation calculations for the proposed pumping station. Clarify whether or not the Class C stream near to the proposed pumping station site has the potential to flood this facility in the event of the 100-year flood. 5) Note that there appears to be a discrepancy with respect to the desired operating conditions for the grinder pump to be installed in the proposed pumping station. Specifically, both the pump specification details on Sheet C2 of the drawings and Sections 13000/13100 of the specifications state that the selected pump is to pump at 25.5 gallons per minute at a total dynamic head of 17 feet. The calculations and the submitted pump curve indicate that the design point is to be only 15.7 feet of total dynamic head at 25.5 gallons per minute. Please amend the design documents and supporting data for consistency. 6) According to the Division's verification calculations, less than two cycles per hour will occur with the current float settings. Please amend the proposed pumping station design so that it complies with Regulation 15A NCAC 211.0219 (h) (2). 7) Note that the Division recommends all corrosion -resistant hardware (i.e., lift -out chain, guide rail system, float bracket, intermediate supports) within pumping station -wet wells to ensure the long-term integrity of the system. Please consider amending the pump specification details on Sheet C2 of the drawings to require all stainless steel hardware. 8) Regulation 15A NCAC 2H-.0219-(h) (8) requires that all-weather access shall be provided to all pumping station sites. The proposed pumping station site plan, as currently designed, does not appear to comply with this rule. Please amend the drawings accordingly. Force Main Design: 1) From review of Section 02660 of the specifications, it appears that Standard Dimensional Ratio (SDR) 35 polyvinyl chloride (PVC) pipe is intended for use throughout the entire subject wastewater collection system. It is the Division's understanding that SDR 35 is not a pressure pipe; therefore, please amend this section of the specifications to include a material specification for the force main. Gravity Sewer Design: 1) Regulation 15A NCAC 2H .0219 (i) (2) (D) requires that the infiltration/exfiltration rate of sewers shall not exceed 100 gallons per day per inch of pipe diameter per mile of pipe installed. Section 02660 of the specifications provides for visual and deflection testing of the gravity sewer following its installation, but does not specify a leakage test. Please amend the specifications accordingly. 2) Regulation 15A NCAC 211.0219 (i) (2) (H) requires that all sewer systems be installed with three feet of cover. If this minimum standard cannot be met, ferrous material pipe shall be specified. Please address the minimum cover issue between STA 16+00 and STA 16+21, which currently appear to and/or may be in violation of the aforementioned rule. 3) - Note that there appears to be a typographical error on Sheet C1 of the drawings. Specifically, the distance between the proposed pumping station and Clean -Out No. 1 is called out as 100 linear feet at a slope of 2.34 percent. Using the relevant station locations and invert elevations, the Division calculated the distance between these two locations as 102 linear feet at 2.29 percent grade. Please correct the drawings accordingly, keeping in mind that the maximum allowable separation between clean -outs is 100 feet. 4) Note that the Division requires that all gravity sewers should be designed and constructed based on the assumption that the pipeline is flowing full. Using this assumption to calculate sewer line velocities, some of the gravity sewer, as currently designed, is subject to excessive velocities (i.e., greater than 15 feet per second). Please explain what measures will be taken to ensure protection of these sewer segments from erosion. 5) Section IV. 3. on Page 2 of 8 of the submitted application form lists the total gravity sewer length as being 1,114 feet. The Division calculated that the gravity sewer was approximately 1,047 feet in length. Please provide a corrected Page 2 of 8 accordingly. 6) Please clarify if there are water wells and/or water lines near the subject wastewater collection sewer that may need to be verified for compliance with the minimum separation requirements detailed in Regulation 15A NCAC 2H .0219 (i) (2) (G). If the water wells and/or water lines have not yet been installed, the Division suggests placing a general note regarding the required minimum separations on the drawings to ensure that the subsequent placing of the items occurs correctly. Please reference the subject permit application number when providing the requested information. All revised information, including letters, calculations, revised drawing sheets, and revised pages of the specifications, should be signed, sealed, and submitted in triplicate to my attention at the address above. Please note that failure to provide this additional information on or before the above requested date can result in your application being returned as incomplete. 0 If you have any questions regarding this request, please call me at (919) 733-5083, extension 353.
