Reason for Visit: Routine
Inspection Summary:
On December 1, 2021, Division of Water Resources staff Caitlin Caudle conducted a schedule compliance and permitting
inspection. Brent Collins of EMA Resources was present during the majority of the inspection. A review of records, permit
application, and application fields was completed. A separate review of residuals analysis was completed in office the
following the inspection. This review reflects compliance with the subject permit.
The address provided for this facility is for a Citgo, but the driveway for the facility is directly across from the Citgo. A more
accurate location for the facility is 35.8038044, -80.5598631.
The WWTP discharges to the South Yadkin River. Roughly, the flow path is pump station ❑ EQ basin ❑ aeration basin ❑
clarifiers ❑ digestor ❑ sludge basin.
The following observations were made:
• According to the permit application, a desired dry tonnage of 2,871 dry tons was requested due to cleaning out the
sludge storage basins for repairs. A permit modification was completed in July 2021 to increase the dry tonnage. Ms. Caudle
clarified that the increased dry tonnage is still needed. As of the date of inspection, both sludge storage basins had been
partially emptied to allow for assessment of repairs.
o The current storage capacity of the facility is the 150,000 gallon digestor and part of the 1.5 MG sludge
basin. The smaller sludge basin was also damaged.
o The normal operations dry tonnage is 315 dry tons/year.
• The permit application states that fecal and 38% volatile solids reduction are used for pathogen and vector reduction.
But the facility used 30-day bench scale test this calendar year. Mr. Collins is going to provide an updated Residuals Source
Certification Form to include 30-day bench scale as an option for vector reduction.
• The WSRO phone number listed in the O&M Plan is outdated, Mr. Collins is going to update the phone number and
provide an updated copy of the O&M Plan.
• TCLP is analyzed annually.
• Nutrients and metals samples are collected from the sludge basin. Multiple samples are collected, and a composite
sample is analyzed.
• Multiple fecal samples are collected on one day. This calendar year samples were collected on 4/26/2021, 6/10/2021,
7/6/2021, and 8/10/2021.
• The metals and nutrient analysis provided with the application was not the same as what was provided in the permit
application. Mr. Collins provided the correct analysis, and the results were consistent with what was provided in the
application.
• TCLP samples were collected on 4/26/2021. All parameters were below permit limits.
• Mr. Collins created updated site maps with updated acreage and buffers.
o DV-008, most of these fields appear to be grazed. A 25% reduction must be applied to grazed fields.
❑ 04 listed Bermuda grass on the LASC form, but the FSF listed fescue. Mr. Collins stated that fescue
was correct. Land clearing changed the acreage of this field. The pond is 100ft from the application area. Deborah
Spillman is no longer listed on the parcel that contains this field.
❑ 05 listed row crop as the crop grown, but a rotation of fescue and small grain is a more
accurate description of the crop. The FSF provided lists the PAN for rye grass as 167 Ib/ac. According to
NC State RYE database, 167 is the PAN rate for pearl millet hay for this soil series, another type of small
grain that can be cut for hay. A previous inspector stated that using the PAN rate of a similar cools
season grass was acceptable as there is not a PAN rate for rye grass in the NC State RYE database.
There is no concern for overapplication. A rock outcropping was located during the inspection. The
approximate location of the rock outcropping is shown on the attached map. Mr. Collins buffered out the
outcropping while Ms. Caudle was on site. Mr. Collins is going to provide an
updated site map with the rock outcropping shown.
❑ 06 listed row crop as the crop grown, but a rotation of fescue and small grain is a more
accurate description of the crop. The FSF provided lists the PAN for rye grass as 198 Ib/ac. According to
NC State RYE database, 198 is the PAN rate for pearl millet hay for this soil series. There is no concern for
over application.
❑ 07 lists PAN on the FSF as 198 Ib/ac. The correct PAN rate for fescue hay for the listed soil

series is 188 Ib/ac.
• 09 listed fescue as the crop grown, but a rotation of fescue and small grain is more accurate. The
crop listed on the FSF is teff, which Mr. Collins stated is a small grain similar to millet.
o DV-012
• The land owner agreement form is missing for these fields.
• Metals field loading and summary forms were only provided for fields 01 and 02. Mr. Collins
stated that they have only applied on these two fields since they were permitted in 2019. The other four
fields have not been applied on yet.
• Updated maps have provided more accurate measurements of acreage.
• A drive by of these fields show that no houses or other buildings have been constructed
near the property that would impact the application area. Greenhouses were on the property, which
may impact the application area. Greenhouses are marked on the attached field map.
o RO-001
• All necessary information was provided for this field. All information appears to be correct.
• This field was not reviewed as Patrick Mitchell reviewed this field in July 2021.
• A single 6,500 gallon pump truck, truck 606, was running at the time of inspection. Hauling had just started during my
inspection of the application field, hauling records were not reviewed. The truck did have the permit and the spill plan. The
project manager for this facility was not present, the technical specialist was there.
• Soil reports were provided via email on 12/1/2021. Only soil reports for DV-008 were provided as that was the only field
applied on last year.
• DV-008-05 and 06 were reviewed during the site visit. The ground cover in 05 was sparse and may need to be reseeded
There was some evidence that areas of 05 had been drilled. All buffers in 05 and 06 were appropriate, with additional areas
that are not on the application buffered out due to seasonal changes. A wetter area and a cow wallow were buffered out in
06. A sign was located at the access gate for the application area. A rain gauge was put on site while Ms. Caudle was
present.
