IV. ADDITIONAL REGIONAL STAFF REVIEW ITEMS
On April 17, 2020, WSRO staff made a site visit to the subject facility for review associated with an application for permit renewal.
Mr. Larry Chilton, ORC and Mr. Russell Welch, Backup ORC accompanied staff on the entire site visit. Mr. Mike Walker, Board
Chairman was present for portions of the WWTP discussions only. There are a number of items which require action and some
items of concern which also require attention. Below is a summary of these items followed by recommendations.
FORM: WQROSSR 04-14 Page 2 of 4
DocuSign Envelope ID: E3D39lB3-8D1B-4F86-8536-050AA8B7AC89
A. The WWTP has two independent treatment trains present: a 30,000 GPD domestic wastewater treatment system and a 60,000
GPD industrial wastewater treatment system (see attached system diagram). Each of these flows independently from each other
into the 588,000-gal effluent storage pond. The items listed below for each treatment train require attention.
Domestic Wastewater Treatment train:
• The domestic wastewater treatment facilities are rusting badly and are in need of maintenance and/or repair.
• According to their Engineer, the current disinfection system was designed for <30,000 GPD and is inadequate for any
greater flow (see attached correspondence). The most recent system plans dated 2006 supports this limit and only shows
the domestic wastewater treatment train connected to disinfection (see attached system diagram).
Industrial Wastewater Treatment train:
• The industrial influent lines reportedly only serve the onsite buildings that were previously used by Lucks Bean Cannery
(i.e. no offsite industrial users were tied into these lines). The cannery is no longer present and the buildings are now used
for mixed uses.
• The industrial wastewater treatment facilities are particularly in bad condition with some units nearly rusted through. These
units are currently not in use and would most likely require major repairs or replacements before being returned to use.
• The preliminary screening system and the DAF units included in the Permit system description are no longer in operation
and it is unknown if these units are operational or even remain connected to the system. These units would likely require
major repair/replacement before being returned to use.
• During the site visit, representatives indicated that there are no industrial waste producers currently present in the onsite
buildings which feed the industrial influent sewer lines. Reportedly there are several businesses now present in the onsite
buildings and several proposed new businesses are planning to move in (including a small brewery). These businesses
reportedly only utilize the domestic wastewater lines only. However, industrial collection lines from these onsite buildings
are still present and connected to the system. These lines have the potential to now carry mixed domestic and industrial
wastes.
According to the attached system diagram, the "industrial non -treated" influent line bypasses the entire WWTP and does
not receive any treatment. This diagram also shows that the "industrial treated" influent line receives treatment but does
not receive any disinfection.
B. The sludge from both treatment trains previously had bypass lines installed from each of the clarifiers, where sludge bypassed
the sludge storage pit and was wasted directly into the 588,000-gal effluent storage pond. The facility is reportedly in the
process of modifying this where sludge will be collected in the sludge pit and subsequently removed from the system.
C. The 2,005,265-gal effluent storage lagoon is reportedly not connected to the system yet. The lagoon has been certified in terms
of construction of the structure itself and a survey was completed confirming the size. However, there has been no confirmation
nor as -built plans produced for connection to the system.
D. Onsite representatives indicated that Lagoon #1 (i.e. the proposed 1,009,563 gallon lagoon) cannot be installed due to the
presence of wetlands resulting in inadequate space.
E. The current Permit Attachment B only list the 40-acre spray field. Therefore, when NDAR data is submitted, it reports the
hourly and annual loading based upon loading to all 40 acres for each irrigation event. However, the spray field has a total of
16 "irrigation lanes" or subzones present. According to representatives, each irrigation event consists of loading either two,
three, or four irrigation subzones; not the entire 40 acres. Operating at —60 PSI for proper spray patterns.
The frequency of use for each individual subzone and the combination of use is at the discretion of the operators. This is leading
to inaccurate reporting for both hydraulic loading and agronomic loading. For example, many NDAR forms consistently report
an hourly loading rate of 0.02 inches/hour and an annual loading rate of 5 to 8 inches/year. Using the NDMR effluent data, the
PAN loading ranges from 25 — 40 lbs. of PAN/acre/year. These values are based upon evenly loading all 40 acres. These values
would likely be reported 4 to 8 times higher based on the acreage utilized for each subzone and how many subzones are being
utilized in any given irrigation event
F. Groundwater sampling results in the two downgradient wells continue to show TDS near or above the 2L limits. In addition,
Chloride levels have been elevated as well. These parameters may be relict of the previous cannery operations, which included
high salt contents. Recommend that this continue to be studied and that the adjacent surface water feature be monitored
periodically by the WSRO for potential impacts.
FORM: WQROSSR 04-14 Page 3 of 4
DocuSign Envelope ID: E3D39lB3-8D1B-4F86-8536-050AA8B7AC89
G. Groundwater sampling results in the two downgradient wells also show Nitrate levels have increased in some sample events,
just below the 2L limit. This could be related to higher nutrient concentrations in effluent resulting from sludge bypassing into
the effluent storage pond. Removal of sludge from the system should improve this.
Another potential contribution is the inaccurate loading of fields as described in item E. above. For example, assuming even
loading over 40 acres = 25 — 40 lbs. PAN/ac./yr, this is well below agronomic limits... However, more accurate loading would
be 4 to 8 times higher based on acres utilized. This would result in annual loading that is potentially over the agronomic limit
of 151 lbs PAN/ac.yr. for portions of the field.
Based on the items described above, the following recommendations are made:
1. Request that two PPI's be generated for the renewed Permit Attachment A. PPI-01 with a max daily flow of 30,000 GPD
(sanitary sewer influent), and PPI-02 with a max daily flow of 80,000 GPD (combined onsite influent of domestic or mixed
domestic -industrial waste). However, use of PPI-02 should be prohibited until the actions listed below are completed. This
could be included in the renewed Permit as a schedule condition.
(1) The 2,005,265-gal effluent storage lagoon is connected and placed into use to provide adequate wet weather
storage,
(2) Modifications to the disinfection system (currently design for <30,000 GPD) are made to accommodate and
disinfect 80,000 GPD,
(3) That all existing industrial influent lines be connected to the treatment facilities (including disinfection) to ensure
the new mixed uses within the onsite buildings are adequately treated, and
(4) That necessary repairs be made to the industrial treatment train and it be returned to use for treating mixed wastes
that are generated into the old industrial lines from onsite buildings. It should be again be noted that there is potential
for wastewater to be generated into these existing lines. Washdown floor drains and sewer connections are still present
in these buildings, and the influent lines are still connected to the system.
2. Request that an updated set of plans for the wastewater treatment facilities be provided. These updated plans should be clearly
labeled, show flow directions within the treatment facilities, show all existing modifications, and show any proposed
modifications (e.g. current work on the sludge storage pit lines, proposed expansion of the disinfection system, replumbing the
old industrial influent lines, adding bar screens to both treatment trains, etc.). Any proposed modifications should be listed
in the renewed Permit with timelines as schedule conditions for completion.
3. There was some discussion during the site visit that the design Engineer may propose a new package treatment plant to
accommodate flows greater than 30,000 GPD, and remove one or both of the old treatment trains. Request that if this proposal
is to be considered with this permitting action, those plans and specifications be submitted. This would be considered a major
modification and require a permitting fee be collected.
4. Request that an update irrigation system site map be submitted that shows the 16 subzones in the spray field along with their
associated acreages. The renewed Permit Attachment B should list all 16 subzones which make up the 40-acre spray field and
future NDAR data should be accurately reported based upon subzones utilized during each irrigation event.
5. Request that a schedule condition be included for a sludge survey of the 588,000 gal effluent storage pond be completed within
the next permit cycle. This is due to sludge currently being wasted into the effluent storage pond.
6. Request that Lagoon #1 described in the description as "construction of', be removed from the permit along with its associated
language and conditions. Due to it not being installed and the onsite representatives indicating that it will not be installed due
to unavailable space.

Re: Wastewater Treatment Facility WQ0002648
Seagrove -Utah Metropolitan Water District, Randolph County, North Carolina
Review of Treatment Capacity
Dear Mike:
Per our previous discussions, LKC Engineering has reviewed the existing treatment process for the above
referenced system. Our review was completed to address the comments for submittal to NCDEQ in
support of your current permit. We reviewed the treatment capacity of each package treatment system
in use at the facility and the treatment capability of the process.
The central focus of the review was to complete an analysis of the package treatment units (30,000 GPD
unit 1 and 60,000 GPD unit 2) working in tandem to treat the domestic waste stream from the water
district customers. We completed this by executing a mathematical model representation of the
existing treatment process to calculate its theoretical capacity. To simulate the seasonal variance of the
plant, the model was executed at the maximum and minimum temperatures that are expected at 45
and 82 degree with a corresponding air temp of 35- and 90-degrees F all while flowing at 90,000 gpd. A
summary report of the plant simulation is attached along with a composite sample of the influent taken
3-12-2019
To further summarize, the 2 package units are capable of treating a domestic wastewater flow of 90,000
gpd (60,000 gpd and 30,000 gpd) to 02T standards for land application. Where the system falls short is
1) that the chlorine contactor appears to have been designed for the 30,000 gpd train and cannot
disinfect the 90,000 gpd flow on anything but the hottest time of year. And 2) it is dangerous to
equipment and reliability to operate a WWTP without adequate screening.
In summary, our review does show that the system meets the capacity of 90,000 gpd. However, it is our
recommendation that you should install proper influent screening, and add volume to the current
chlorine contact chamber. Our recommendation is to install a bar screen at the influent box or at an
upstream manhole , and expand the contact chamber to a minimum 4200 gallons or explore installing
UV disinfection. Our office can assist in providing design and permitting assistance for this work. Since
we have the model calculations of your plant completed we could attack permitting calculations in short
order.
