To determine this, we found the volume available in the wet well at the worst case scenario (if the power was to go out and the liquid level was at the pump on float). The elevation from the pump on float to the rim of the wet well was 10.25' and using the diameter of the wet well (4 ft), we found the available volume was approximately 128 cubic feet, or just over 963 gallons. (the top of the wet well would be the first overflow point on the site and is lower than the building's finished flow elevation — see the attached utility profiles) To find the influent flow rate to the station, we calculated the average daily flow rate per resident from historical water consumption data from two similar Carillon facilities (one in Knightdale, the other in Fuquay). That hourly flow rate was multiplied by the total number of beds for the Durham facility (84 beds) and converted that daily fiowrate to an average gallons per minute, which was approximately 8.08 gal/min. Dividing the available storage volume by the by the maximum average influent rate provides —119 minutes. It is important to note that this timing does NOT account for water -use reduction procedures if the pump station power is lost. Narrative There are a couple of significant factors to consider for the reliability of this pump station: • This lift station serves a single building that is staffed 24 hours a days, 365 days a year. • The power feed wiring to the station is protected in a conduit to reduce the risk of accidental severing. • The station has alarms that alert staff there is a problem so they can curtail water using activities while service is called and on the way. • Carillon has a multiple generators used to power facilities in the event of a power outage. • Carillon has a contract with Stanley Environmental for a pump truck in the event of any difficulties/delay in generator deployment. Please review the above information and the attached drawings and don't hesitate to let me know if you have additional questions or need more information. We would appreciate anything you can do to expedite review on your end. Again, please let me know if there is anything I can do to help!

Below is her comment: Based on our general interpretation of 15A NCAC 02T.0305(h) with regards to the two power source requirement as well as the MDC requirements you outlined, I do not believe a single source via the incoming line (whether it is from the standard power or a generator) would suffice, especially because as you mentioned, if that one line gets cut either during a power outage or during a normal day, they have no way to power the pump station. They would need to have some method of hooking up the generator directly to the pump station in the event that the line to the pump station fails while the nursing home has power. I'm not sure that we would grant a variance far this unless they have significant storage in the wet well above the pump -on elevation — we've granted variances for simplex pump stations to be used with no backup power and 24-hours of storage above the pump -on for small flows, but I'm not sure how much flow this particular nursing home generates nor how large the wet well is in relation to the flow. We'd need to delve into the design information to determine if we could consider a variance — perhaps the engineer can provide the plans and brief calculations (digital is fine) showing the storage above the pump -on position so we can see what we would consider? Can you provide more specifics on the pump station, wet well storage capacity, talcs, narrative, etc? We'll review and let you know something.

Item VI11.6 notes a portable power source for the proposed pump station, however, the narrative states the entire facility is connected to an emergency power generator. Just to clarify, is the generator a portable power source, or, is it a permanent generator? Upon confirmation and with your permission, we'll make the revision on the application. Also we need item V of the application completed (downstream sewer permit number, receiving sewer size, system wide collection system permit number, owner name). Just to confirm, will duplex grinder pumps be installed in the pump station?

Please insert a condition into the permit as follows (please feel free to tweak the language if needed): "The pump station shall be provided with a manual transfer switch and portable generator quick -connection receptacle such that a portable generator could be obtained and connected to the pump station, should the conduit between the main building and the pump station fail to convey adequate power for the operation of the pump station, per Section 5.04(13)(3)(b) of the Minimum Design Criteria" Christyn L.

To determine this, we found the volume available in the wet well at the worst case scenario (if the power was to go out and the liquid level was at the pump on float). The elevation from the pump on float to the rim of the wet well was 10.25' and using the diameter of the wet well (4 ft), we found the available volume was approximately 128 cubic feet, or just over 963 gallons. (the top of the wet well would be the first overflow point on the site and is lower than the building's finished flow elevation — see the attached utility profiles) To find the influent flow rate to the station, we calculated the average daily flow rate per resident from historical water consumption data from two similar Carillon facilities (one in Knightdale, the other in Fuquay). That hourly flow rate was multiplied by the total number of beds for the Durham facility (84 beds) and converted that daily flowrate to an average gallons per minute, which was approximately 8.08 gal/min. Dividing the available storage volume by the by the maximum average influent rate provides —119 minutes. It is Important to note that this timing does NOT account for water -use reduction procedures if the pump station power Is lost Narrative There are a couple of significant factors to consider for the reliability of this pump station: • This lift station serves a single building that is staffed 24 hours a days, 365 days a year. • The power feed wiring to the station is protected in a conduit to reduce the risk of accidental severing. • The station has alarms that alert staff there is a problem so they can curtail water using activities while service is called and on the way. • Carillon has a multiple generators used to power facilities in the event of a power outage. • Carillon has a contract with Stanley Environmental for a pump truck in the event of any difficulties/delay in generator deployment. Please review the above information and the attached drawings and don't hesitate to let me know if you have additional questions or need more information. We would appreciate anything you can do to expedite review on your end. Again, please let me know if there is anything I can do to helpl Very Respectfully, Chris Christopher Petree, PE, DBIA Water Infrastructure — Sr. Project Manager TIMMONS GROUP I www.timmons.com 5410 Trinity Road, Suite 102 1 Raleigh, NC 27607 Office: 919.532.3234 1 Fax: 919.859.5563 chris.oetree0timmons.com Your Vision Achieved Through Ours Front: Cashion, Ted <ted.cashion@ncdenr.sov> Sent: Tuesday, April 30, 2019 8:08 AM To: Chris Petree <Chris.Petree@timmons.com>; bsteenson@carillonassistedliving.com Cc: Robinson, Jason <iason.t.robinson@ncdenr.eov>; Fertenbaugh, Christyn L<christyn.fertenbaugh@ncdenr.gov> Subject: RE: [External] RE: Carillon Durham fast track sewer extension application Chris, We discussed the backup power scenario in-house and with our permit coordinator. Below is her comment: Based on our general interpretation of 15A NCAC 02T.0305(h) with regards to the two powersource requirement as well as the MDC requirements you outlined, 1 do not believe a single source via the incoming line (whether it is from the standard power or a generator) would suffice, especially because as you mentioned, if that one line gets cut either during a power outage or during a normal day, they have no way to power the pump station. They would need to have some method of hooking up the generator directly to the pump station in the event that the line to the pump station fails while the nursing home has power. I'm not sure that we would grant a variance for this unless they have significant storage in the wet well above the pump - on elevation — we've granted varionces for simplex pump stations to be used with no backup power and 24-hours of storage above the pump -on for small flows, but I'm not sure how much flow this particular nursing home generates nor how large the wet well is in relation to the flow. We'd need to delve into the design information to determine if we could consider a variance — perhaps the engineer can provide the plans and brief calculations (digital is fine) showing the storage above the pump -on position so we con see what we would consider? Can you provide more specifics on the pump station, wet well storage capacity, calcs, narrative, etc? We'll review and let you know something.
