with a tractor powered Houle pump to achieve a well -mixed and consistent
material that is suitable for land application. It is going to be spread at
agronomic rates that are determined using the Realistic Yield Expectations (RYE)
as outlined in the permit, the amount of other nutrient sources the landowner
and operator has applied, and the residuals nutrient and metal sample that is
current for that monitoring period. It is going to be spread with a liquid
applicator that will use pressure to spread the material in such a way as to
achieve a consistent spread pattern. The material is going to be land applied on
fields that have a crop growing on them that are going to either be grazed or cut
for animal feed. Application rates will be reduced by 25% on fields that are
primarily used for grazing in accordance with USDA-NRCS 590. Grazed fields will
be determined by the farmers and EMA project managers.
4. Maintenance Schedule

a. EMA Resources Inc. will follow the maintenance schedule as recommended by
the EMA Resources Operations Manager (Mike Collins) for the equipment
necessary to complete the job.

personnel where to get the straw, lime, and other items necessary to
complete the clean-up operation. le. local farmers, farm supply centers,
nurseries.
iv. Initial Clean-up: Employ front-end loaders, vacuum equipment, sludge
application vehicles, and/or local septic tank service to remove as much
of the spilled material as possible. Straw and/or sand should be scattered
in the spill area to soak up the remaining material. The straw and sand
soaked material will be collected and removed to a disposal area
approved by representatives of the state regulatory agency.
v. Final Clean-up: Employ rotary brush sweeper if needed and apply lime
to the spill area upon the approval of the clean-up efforts by the state
regulatory representative. If the event occurs on private property, the
clean-up will be completed to the satisfactory of the property owner and

state regulatory representatives. The ultimate goal will be restore the
spill area to its original condition if possible.
vi. Notification: As soon as possible after the spill occurs, the EMA
Resources Project Manager or designee will notify the Davidson Water

shall be called to report all incidences [phone].
7. Inspection Plan
a. Inspection for the land application of residuals will conducted on a minimum of
a weekly basis at the land application site during land application activities. The
inspection frequency is based on the time frame that it is going to take to
complete the project and the amount of dry tons to be land applied from this
facility. The inspections will consist of inspecting a current field that is being
applied as well as inspecting random fields that have been completed.
Inspections will be conducted by Jeff Thompson - Project Manager, and Boger
Hartsell - Project Manager. These inspections will consist of the following:
i. Verifying the application rates for each field that plan on receiving
material.
ii. Checking the calculated loads to ensure the correct amount of residuals
are being land applied.
iii. Ensure that all manned equipment has a copy of the permit and the
operation and maintenance plan.
iv. Ensure that the field has been flagged properly and that all buffers are
being adhered to.
v. Ensure proper signage has been posted
vi. Verify that the proper number of samples of the residuals have been
taken and that it meets the criteria for land application.

6. Any release that requires immediate reporting outside normal
business hours shall be called in by EMA Resources staff to DENR
at [phone]. This number is to be called in the event of a
release to surface waters or imminent failure of a storage system
when the event occurs outside of normal business hours.
8. Sampling and Monitoring Plan
a. Sampling for this project consists of sampling the residuals prior to land
application occurring in order to ensure that the residuals are suitable for land
application.
b. The samples will be collected from the storage lagoon that holds the residuals
c. Boger Hartsell, Brent Collins, or other designee will be responsible for sample
collection for nutrient and metal, and TCLP.
d. Nutrient, metal and TCLP sample aliquots will be collected randomly and consist
of at least 7 individual aliquots mixed together in order to get the composite
sample for these parameters.
e. The residuals will be sampled once per permit cycle for TCLP including the RClls.
f. Metal and nutrient parameters will be collected and analyzed based on the

Dear Brent Collins:
Waypoint Analytical, LLC. received sample(s) on 1/10/2020 for the analyses presented in the following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method. Where the laboratory was not responsible for the sampling
stage (refer to the chain of custody) results apply to the sample as received.
The analytical data has been validated using standard quality control measures performed as required by the
analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters (NELAP and non-NELAP) were performed in accordance with guidelines established by the USEPA
(including 40 CFR 136 Method Update Rule August 2017) and NELAC unless otherwise indicated. Any
parameter for which the laboratory is not officially NELAP accredited is indicated by a '—' symbol. These are not
included in the scope because NELAP accreditation is either not available or has not been applied for. Additional
certifications may be held/are available for parameters, where NELAP accreditation is not required or applicable.
A full list of certifications is available upon request.
Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time.
Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as -
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to
the samples included in this report.
Please do not hesitate to contact me or client services if you have any questions or need additional information.
Sincerely,
Danyale Love
Project Manager
Laboratory's liability in any claim relating to analyses performed shall be limited to, at laboratory's option, repeating the
analysis in question at laboratory's expense, or the refund of the charges paid for performance of said analysis.

Dear Brent Collins:
Waypoint Analytical, LLC. received sample(s) on 10/23/2020 for the analyses presented in the following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method. Where the laboratory was not responsible for the sampling
stage (refer to the chain of custody) results apply to the sample as received.
The analytical data has been validated using standard quality control measures performed as required by the
analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters (NELAP and non-NELAP) were performed in accordance with guidelines established by the USEPA
(including 40 CFR 136 Method Update Rule August 2017) and NELAC unless otherwise indicated. Any
parameter for which the laboratory is not officially NELAP accredited is indicated by a '—'symbol. These are not
included in the scope because NELAP accreditation is either not available or has not been applied for. Additional
certifications may be held/are available for parameters, where NELAP accreditation is not required or applicable.
A full list of certifications is available upon request.
Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time.
Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as -
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to
the samples included in this report.
Please do not hesitate to contact me or client services if you have any questions or need additional information.
Sincerely,
Danyale Love
Project Manager
Laboratory's liability in any claim relating to analyses performed shall be limited to, at laboratory's option, repeating the
analysis in question at laboratory's expense, or the refund of the charges paid for performance of said analysis.
Ijp,

CASE NARRATIVE
ONE LAB. NATIONWIDE. *
All MDL (LOD) and RDL (LOQ) values reported for environmental samples have been corrected for the FP
dilution factor used in the analysis. All Method and Batch Quality Control are within established criteria except where addressed in this case narrative, a non-conformance form or properly qualified within the F
sample results. By my digital signature below, I affirm to the best of my knowledge, all
problems/anomalies observed by the laboratory as having the potential to affect the quality of the data have been identified by the laboratory, and no information or data have been knowingly withheld that F
would affect the quality of the data.
