To Whom It May Concern:
Enclosed are three copies of the 2018 Annual Land Application Report Forms and Laboratory Analysis
Reports as required by Permit Number WQ0013276 issued to New England Fertilizer Company (NEFCO).
This permit provides for the distribution of heat -dried biosolids produced by NEFCO at the processing
facility located in Quincy, Norfolk County, Massachusetts.
In October 2016 two more NEFCO plants were added — in West Palm Beach, FL and Cumberland, MD.
None of these plants shipped to NC during 2018. Therefore a DMSDF Form, showing 0 tons shipped, is
included for each of them.
The attachments include analytical data of NEFCO's pellet biosolids during year 2018 for:
- Baseline metals, nutrients and nitrogen. The monthly composite samples were analyzed by
Waypoint Analytical, in Richmond, VA and Eurofins Spectrum Analytical, in Agawam, MA
- Fecal coliform. The monthly grab samples were analyzed by ESS Labs, in Cranston, RI
- TCLP. The annual composite sample was analyzed by Eurofins Spectrum Analytical, in Agawam,
MA
During 2018 NEFCO-Quincy, MA shipped 164.22 dry tons of Class A EQ biosolids to the state of North
Carolina. All the product was used for agricultural land -application, and was managed by 3 users - Jim
Stanaland, Will Stanaland and Wesley King.
Sincerely,
Michael V. Ryan

This signed Certificate of Analysis is our approved release of your analytical results. These results are
only representative of sample aliquots received at the laboratory. ESS Laboratory expects its clients to
follow all regulatory sampling guidelines. Beginning with this page, the entire report has been paginated.
This report should not be copied except in full without the approval of the laboratory. Samples will be
disposed of thirty days after the final report has been delivered. If you have any questions or concerns,
please feel free to call our Customer Service Department.

Laboratory Director
Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW -846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

RE: Biosolids Fecal Coli (N/A)
ESS Laboratory Work Order Number: 1802310
This signed Certificate of Analysis is our approved release of your analytical results. These results are
only representative of sample aliquots received at the laboratory. ESS Laboratory expects its clients to
follow all regulatory sampling guidelines. Beginning with this page, the entire report has been paginated.
This report should not be copied except in full without the approval of the laboratory. Samples will be
disposed of thirty days after the final report has been delivered. If you have any questions or concerns,
please feel free to call our Customer Service Department.

Laboratory Director
Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW -846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

Chloride - Chloridometer Method SM-4500CI-D
Analyte: Cl
QC Batch No: E63524
Due to limitations within the LIMS system, when analyzing sludge batches for chloride, the CCV associated with
verifying the calibration of the electrode does not evaluate correctly. It indicates 0% recovery. The actual
recovery for the CCV associated with this batch is %.
Nitrate + Nitrite Nitrogen Method SM-4500NO3F
Sample 59801
Analyte: NO3+NO2-N
QC Batch No: E63503
The MS/MSD recoveries are considered insignificant due to the level of analyte present in the parent sample
relative to the spike level . RPD is based on the MS/MSD results and should be evaluated as laboratory
duplicates.
Refer to LCS/LCSD.
Metals Analysis Method SW -6010C
Sample 59840 (EQ Biosolids)
Analyte: Al
QC Batch No: E63514/E63474

This signed Certificate of Analysis is our approved release of your analytical results. These results are
only representative of sample aliquots received at the laboratory. ESS Laboratory expects its clients to
follow all regulatory sampling guidelines. Beginning with this page, the entire report has been paginated.
This report should not be copied except in full without the approval of the laboratory. Samples will be
disposed of thirty days after the final report has been delivered. If you have any questions or concerns,
please feel free to call our Customer Service Department.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW -846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

Nitrate + Nitrite Nitrogen Method SM-4500NO3F
Sample 60536
Analyte: NO3+NO2-N
QC Batch No: E63874
RPD between MS/MSD results fails. MS/MSD recoveries both within QC limits. Since all other QC data passes,
results are acceptable.
QC Batch No: E63874
The MS/MSD recoveries are considered insignificant due to the level of analyte present in the parent sample
relative to the spike level . RPD is based on the MS/MSD results and should be evaluated as laboratory
duplicates.

This signed Certificate of Analysis is our approved release of your analytical results. These results are
only representative of sample aliquots received at the laboratory. ESS Laboratory expects its clients to
follow all regulatory sampling guidelines. Beginning with this page, the entire report has been paginated.
This report should not be copied except in full without the approval of the laboratory. Samples will be
disposed of thirty days after the final report has been delivered. If you have any questions or concerns,
please feel free to call our Customer Service Department.
Laurel Stoddard
Laboratory Director
Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW -846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

Dear Jordan Dimitrov:
Waypoint Analytical Virginia, Inc. received sample(s) on 6/8/2018 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. Sub -contracted testing is noted on the Sample Summary Table
if applicable.
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 May 2012) and NELAC unless otherwise indicated.
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,
�a f• c—r
Pauric McGroary

This signed Certificate of Analysis is our approved release of your analytical results. These results are
only representative of sample aliquots received at the laboratory. ESS Laboratory expects its clients to
follow all regulatory sampling guidelines. Beginning with this page, the entire report has been paginated.
This report should not be copied except in full without the approval of the laboratory. Samples will be
disposed of thirty days after the final report has been delivered. If you have any questions or concerns,
please feel free to call our Customer Service Department.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW -846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

Dear Jordan Dimitrov:
Waypoint Analytical Virginia, Inc. received sample(s) on 7/13/2018 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. Sub -contracted testing is noted on the Sample Summary Table
if applicable.
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 May 2012) and NELAC unless otherwise indicated.
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,
�a f• c—r
Pauric McGroary
Agronomist
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.

This signed Certificate of Analysis is our approved release of your analytical results. These results are
only representative of sample aliquots received at the laboratory. ESS Laboratory expects its clients to
follow all regulatory sampling guidelines. Beginning with this page, the entire report has been paginated.
This report should not be copied except in full without the approval of the laboratory. Samples will be
disposed of thirty days after the final report has been delivered. If you have any questions or concerns,
please feel free to call our Customer Service Department.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW -846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

accordance with the applicable analytical method. Sub -contracted testing is noted on the Sample Summary Table
if applicable.
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 May 2012) and NELAC unless otherwise indicated.
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,

This signed Certificate of Analysis is our approved release of your analytical results. These results are
only representative of sample aliquots received at the laboratory. ESS Laboratory expects its clients to
follow all regulatory sampling guidelines. Beginning with this page, the entire report has been paginated.
This report should not be copied except in full without the approval of the laboratory. Samples will be
disposed of thirty days after the final report has been delivered. If you have any questions or concerns,
please feel free to call our Customer Service Department.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW -846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

Dear Jordan Dimitrov:
Waypoint Analytical Virginia, Inc. received sample(s) on 9/7/2018 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. Sub -contracted testing is noted on the Sample Summary Table
if applicable.
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 May 2012) and NELAC unless otherwise indicated.
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,
�a f• c—r
Pauric McGroary
Agronomist
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.

This signed Certificate of Analysis is our approved release of your analytical results. These results are
only representative of sample aliquots received at the laboratory. ESS Laboratory expects its clients to
follow all regulatory sampling guidelines. Beginning with this page, the entire report has been paginated.
This report should not be copied except in full without the approval of the laboratory. Samples will be
disposed of thirty days after the final report has been delivered. If you have any questions or concerns,
please feel free to call our Customer Service Department.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW -846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
(J -Flag).
All non -detects and all results below the reporting limit are reported as "<" (less than) the reporting limit in this report.
The samples were received 1.3 degrees Celsius, please refer to the Chain of Custody for details specific to temperature upon receipt.
An infrared thermometer with a tolerance of +/- 1.0 degrees Celsius was used immediately upon receipt of the samples.
If a Matrix Spike (MS), Matrix Spike Duplicate (MSD) or Duplicate (DUP) was not requested on the Chain of Custody, method
criteria may have been fulfilled with a source sample not of this Sample Delivery Group. If method or program required
MS/MSD/Dup were not performed, sufficient sample was not provided to the laboratory.
Analyses for Total Hardness, pH, and Total Residual Chlorine fall under the state of Pennsylvania code Chapter 252.6 accreditation by
rule.

Notes and Definitions
cl TKN is reported as Organic Nitrogen in the Blank, LCS, DUP and MS.
D Data reported from a dilution
E This flag indicates the concentration for this analyte is an estimated value due to exceeding the calibration range or
interferences resulting in a biased final concentration.
GSI Sample dilution required for high concentration of target analytes to be within the instrument calibration range.
HT5 Sample was originally analyzed within the recommended method holding time; however, QC materials for the sample run
were out of control. As a result, the sample was immediately re -analyzed (outside the holding time).
009 This sample was analyzed outside the EPA recommended holding time per client request.
Q1 This parameter is not certified by MA for this matrix.
QM2 The RPD and/or percent recovery for this QC spike sample cannot be accurately calculated due to the high concentration
of analyte inherent in the sample.
QM4X The spike recovery was outside of QC acceptance limits for the MS, MSD and/or PS due to analyte concentration at 4
times or greater the spike concentration. The QC batch was accepted based on LCS and/or LCSD recoveries within the
acceptance limits.
QR6 The RPD exceeded the QC control limits; however precision is demonstrated with acceptable RPD values for MS/MSD.
R04 The Reporting Limits for this analysis are elevated due to sample foaming.
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
J Detected but below the Reporting Limit; therefore, result is an estimated concentration (CLP J -Flag).
pH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
HD Total Hardness is a calculation based on the reported values of Ca and Mg.

Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra -laboratory split sample which is used to document the precision of a method in a given sample matrix.
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte -free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank
is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample
RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

This is a summary of year 2018 results so far, and one monthly report. You can
see that our results are steady and what the values usually are. Also, it can be
seen which testing methods were used. You do not need to use exactly the same
testing methods. Any EPA or state environmental agency approved method, for
which your Lab is certified, is fine.

Dear Jordan Dimitrov:
Waypoint Analytical Virginia, Inc. received sample(s) on 6/8/2018 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. Sub -contracted testing is noted on the Sample Summary Table
if applicable.
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 May 2012) and NELAC unless otherwise indicated.
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,
�a f• c—r

RE: Biosolids Fecal Coli (N/A)
ESS Laboratory Work Order Number: 1809641
This signed Certificate of Analysis is our approved release of your analytical results. These results are
only representative of sample aliquots received at the laboratory. ESS Laboratory expects its clients to
follow all regulatory sampling guidelines. Beginning with this page, the entire report has been paginated.
This report should not be copied except in full without the approval of the laboratory. Samples will be
disposed of thirty days after the final report has been delivered. If you have any questions or concerns,
please feel free to call our Customer Service Department.
Laurel Stoddard
Laboratory Director
Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW -846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
(J -Flag).
All non -detects and all results below the reporting limit are reported as "<" (less than) the reporting limit in this report.
The samples were received 1.0 degrees Celsius, please refer to the Chain of Custody for details specific to temperature upon receipt.
An infrared thermometer with a tolerance of +/- 1.0 degrees Celsius was used immediately upon receipt of the samples.
If a Matrix Spike (MS), Matrix Spike Duplicate (MSD) or Duplicate (DUP) was not requested on the Chain of Custody, method
criteria may have been fulfilled with a source sample not of this Sample Delivery Group. If method or program required
MS/MSD/Dup were not performed, sufficient sample was not provided to the laboratory.
Analyses for Total Hardness, pH, and Total Residual Chlorine fall under the state of Pennsylvania code Chapter 252.6 accreditation by
rule.
See below for any non -conformances and issues relating to quality control samples and/or sample analysis/matrix.

Notes and Definitions
cl TKN is reported as Organic Nitrogen in the Blank, LCS, DUP and MS.
D Data reported from a dilution
GSI Sample dilution required for high concentration of target analytes to be within the instrument calibration range.
009 This sample was analyzed outside the EPA recommended holding time per client request.
QM2 The RPD and/or percent recovery for this QC spike sample cannot be accurately calculated due to the high concentration
of analyte inherent in the sample.
QM7 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable
LCS recovery.
QM8 The spike recovery exceeded the QC control limits for the MS and/or MSD. The batch was accepted based upon
acceptable PS and /or LCS recovery.
QM9 The spike recovery for this QC sample is outside the established control limits. The sample results for the QC batch were
accepted based on LCS/LCSD or SRM recoveries within the control limits.
QR6 The RPD exceeded the QC control limits; however precision is demonstrated with acceptable RPD values for MS/MSD.
R Quality Control is outside acceptance range; all affected samples have been re -analyzed.
R04 The Reporting Limits for this analysis are elevated due to sample foaming.
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
J Detected but below the Reporting Limit; therefore, result is an estimated concentration (CLP J -Flag).
pH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra -laboratory split sample which is used to document the precision of a method in a given sample matrix.
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte -free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank
is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample
RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

This signed Certificate of Analysis is our approved release of your analytical results. These results are
only representative of sample aliquots received at the laboratory. ESS Laboratory expects its clients to
follow all regulatory sampling guidelines. Beginning with this page, the entire report has been paginated.
This report should not be copied except in full without the approval of the laboratory. Samples will be
disposed of thirty days after the final report has been delivered. If you have any questions or concerns,
please feel free to call our Customer Service Department.

Laboratory Director
Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW -846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
(J -Flag).
All non -detects and all results below the reporting limit are reported as "<" (less than) the reporting limit in this report.
The samples were received 4.3 degrees Celsius, please refer to the Chain of Custody for details specific to temperature upon receipt.
An infrared thermometer with a tolerance of +/- 1.0 degrees Celsius was used immediately upon receipt of the samples.
If a Matrix Spike (MS), Matrix Spike Duplicate (MSD) or Duplicate (DUP) was not requested on the Chain of Custody, method
criteria may have been fulfilled with a source sample not of this Sample Delivery Group. If method or program required

Notes and Definitions
cl TKN is reported as Organic Nitrogen in the Blank, LCS, DUP and MS.
D Data reported from a dilution
GSI Sample dilution required for high concentration of target analytes to be within the instrument calibration range.
QM2 The RPD and/or percent recovery for this QC spike sample cannot be accurately calculated due to the high concentration
of analyte inherent in the sample.
QM7 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable
LCS recovery.
ROI The Reporting Limit has been raised to account for matrix interference.
R04 The Reporting Limits for this analysis are elevated due to sample foaming.
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
pH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra -laboratory split sample which is used to document the precision of a method in a given sample matrix.
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte -free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank
is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample
RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
(J -Flag).
All non -detects and all results below the reporting limit are reported as "<" (less than) the reporting limit in this report.
The samples were received 3.3 degrees Celsius, please refer to the Chain of Custody for details specific to temperature upon receipt.
An infrared thermometer with a tolerance of +/- 1.0 degrees Celsius was used immediately upon receipt of the samples.
If a Matrix Spike (MS), Matrix Spike Duplicate (MSD) or Duplicate (DUP) was not requested on the Chain of Custody, method
criteria may have been fulfilled with a source sample not of this Sample Delivery Group. If method or program required
MS/MSD/Dup were not performed, sufficient sample was not provided to the laboratory.
See below for any non -conformances and issues relating to quality control samples and/or sample analysis/matrix.

Notes and Definitions
cl TKN is reported as Organic Nitrogen in the Blank, LCS, DUP and MS.
m This parameter is outside laboratory ms/msd specified recovery limits.
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
pH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra -laboratory split sample which is used to document the precision of a method in a given sample matrix.
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte -free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank
is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample
RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW -846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
(J -Flag).
All non -detects and all results below the reporting limit are reported as "<" (less than) the reporting limit in this report.
The samples were received 0.6 degrees Celsius, please refer to the Chain of Custody for details specific to temperature upon receipt.
An infrared thermometer with a tolerance of +/- 1.0 degrees Celsius was used immediately upon receipt of the samples.
If a Matrix Spike (MS), Matrix Spike Duplicate (MSD) or Duplicate (DUP) was not requested on the Chain of Custody, method
criteria may have been fulfilled with a source sample not of this Sample Delivery Group. If method or program required
MS/MSD/Dup were not performed, sufficient sample was not provided to the laboratory.
All VOC soils samples submitted and analyzed in methanol will have a minimum dilution factor of 50. This is the minimum amount of
solvent allowed on the instrumentation without causing interference. Soils are run on a manual load instrument. 100ug of sample
(MEOH) is spiked into 5ml DI water along with the surrogate and added directly onto the instrument. Additional dilution factors may
be required to keep analyte concentration within instrument calibration range.
See below for any non -conformances and issues relating to quality control samples and/or sample analysis/matrix.
SW8461311/6010C
Laboratory Control Samples:
1815264 BS/BSD
Selenium percent recoveries (123/122) are outside individual acceptance criteria (85-115), but within overall method allowances.
All reported results of the following samples are considered to have a potentially high bias:
Class A EQ Biosolids
Spikes:
1815264-MS1 Source: SC51998-01
Analyte out of acceptance range in QC spike but no reportable concentration present in sample.
Selenium

Analyte out of acceptance range in QC spike but no reportable concentration present in sample.
Selenium
Duplicates:
1815264-DUP1 Source: SC51998-01
Analyses are not controlled on RPD values from sample concentrations that are less than 5 times the reporting level. The batch is
accepted based upon the difference between the sample and duplicate is less than or equal to the reporting limit.

Notes and Definitions
D Data reported from a dilution
GSI Sample dilution required for high concentration of target analytes to be within the instrument calibration range.
QC2 Analyte out of acceptance range in QC spike but no reportable concentration present in sample.
QM7 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable
LCS recovery.
QR8 Analyses are not controlled on RPD values from sample concentrations that are less than 5 times the reporting level. The
batch is accepted based upon the difference between the sample and duplicate is less than or equal to the reporting limit.
SDUP Duplicate analysis confirmed surrogate failure due to matrix effects.
SGC Surrogate recovery outside of control limits. The data was accepted based on valid recovery of the remaining surrogate.
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
[2C] Indicates concentration was reported from the secondary, confirmation column.
J Detected but below the Reporting Limit; therefore, result is an estimated concentration (CLP J -Flag).
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra -laboratory split sample which is used to document the precision of a method in a given sample matrix.
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte -free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank
is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample
RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

This signed Certificate of Analysis is our approved release of your analytical results. These results are
only representative of sample aliquots received at the laboratory. ESS Laboratory expects its clients to
follow all regulatory sampling guidelines. Beginning with this page, the entire report has been paginated.
This report should not be copied except in full without the approval of the laboratory. Samples will be
disposed of thirty days after the final report has been delivered. If you have any questions or concerns,
please feel free to call our Customer Service Department.

Laboratory Director
Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW -846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

there is no discharge to surface waters, nor any contravention of groundwater or surface water
standards. In the event the facilities fail to perform satisfactorily, including the creation of nuisance
conditions due to improper operation and maintenance, the Permittee shall immediately cease
distribution of residuals, contact the nearest regional office supervisor, and take any immediate
corrective actions (see http://portal.ncdenr.org/web/wqlaps). [G.S. 143-215.1]
WQ0013276 Version 4.0 Shell Version 150101 Page l of 12

9. Bulk residuals and other sources of Plant Available Nitrogen (PAN) shall not be applied in
exeeedance of agronomic rates. Appropriate agronomic rates shall be calculated using expected
nitrogen requirements based on the determined Realistic Yield Expectations (RYE) using any of the
following methods:
a. Division's pre -approved site specific historical data for specific crop or soil types by calculating
the mean of the best three yields of the last five consecutive crop harvests for each field.
b. North Carolina Historical Data for specific crop and soil types as provided by North Carolina
State University Department of Soil Science (http:Hnutrients.soil.ncsu.edu/yields/index.php).
A copy shall be kept on file and reprinted every five years in accordance with Condition IV.6.
c. If the RYE cannot be determined using methods (a) or (b) above, the Permittee may use the RYE
and appropriate nutrient application rates reported in any of the following documents:
i. Crop management plan as outlined by the local Cooperative Extension Office, the North

[15A NCAC 02T. 11081
8. Specific residuals Iand application area boundaries shall be clearly marked on each land application
site prior to and during a bulk residuals land application event. [15A NCAC 02C .0105(f), 02T
A 108(b)(2)]
9. Bulk residuals and other sources of Plant Available Nitrogen (PAN) shall not be applied in
exeeedance of agronomic rates. Appropriate agronomic rates shall be calculated using expected
nitrogen requirements based on the determined Realistic Yield Expectations (RYE) using any of the
following methods:
a. Division's pre -approved site specific historical data for specific crop or soil types by calculating
the mean of the best three yields of the last five consecutive crop harvests for each field.
b. North Carolina Historical Data for specific crop and soil types as provided by North Carolina
State University Department of Soil Science (http:Hnutrients.soil.ncsu.edu/yields/index.php).
A copy shall be kept on file and reprinted every five years in accordance with Condition IV.6.
c. If the RYE cannot be determined using methods (a) or (b) above, the Permittee may use the RYE
and appropriate nutrient application rates reported in any of the following documents:
i. Crop management plan as outlined by the local Cooperative Extension Office, the North
Carolina Department of Agriculture and Consumer Services, the Natural Resource
Conservation Service, or other agronomist.

10. The Permittee shall not distribute Econo-Grow that have a sodium adsorption ratio (SAR) of 10 or
higher without prior written Division approval. The Permittee may seek approval by demonstrating
that the entity accepting the residuals is: aware of the effects of a high SAR content; has agreed on
proper residual application rates; and has agreed to operational considerations to ensure that the high
SAR content will not adversely impact the receiving sites. Recommendations regarding sodium
application rate, soil amendments (e.g., gypsum, etc.) or a mechanism for maintaining site integrity
and conditions conducive to crop growth, can be obtained from the local Cooperative Extension
Office, the Department of Agriculture and Consumer Services, the Natural Resource Conservation
Service, a North Carolina Licensed Soil Scientist, or an agronomist. [15A NCAC 02T .0108(b)(1)]
11. If the land application sites are to be overseeded or doublecropped (e.g., bermuda grass in the summer
and rye grass in the winter with BOTH crops to receive residuals or corn and small grain both to
receive residuals), then the second crop shall receive an application of PAN at a rate of no greater
than 50 pounds per acre per year. This practice shall be allowed as long as the second crop is to be
harvested. If the second crop is to be planted for erosion control only and is to be tilled into the soil,
then no residuals shall be land applied to these sites because the PAN will essentially be returned to
the soil.
Prior to application of PAN to permitted sites at rates exceeding the agronomic rate, the Permittee
must submit and receive approval by the Division. [15A NCAC 02T .0108(b)(1)]
12. For land application sites, the compliance boundary is established at either 250 feet from the residual
land application area, or 50 feet within the property boundary, whichever is closest to the residual
land application area. An exceedance of groundwater standards at or beyond the compliance
boundary is subject to remediation action according to 15A NCAC 02L .0106(d)(2) as well as
enforcement actions in accordance with North Carolina General Statute 143-215.6A through 143-
215.6C. [ 15A NCAC 02L .0107(a)]
13. For land application sites, the review boundary shall be established midway between the compliance
boundary and the residual land application area. Any exceedance of groundwater standards at the
review boundary shall require action in accordance with. 15A NCAC 02L .0106. [15A NCAC 02L
.0108]
III. OPERATION AND MAINTENANCE REQUIREMENTS
The residuals management program shall be properly maintained and operated at all times. The
program shall be effectively maintained and operated as a non -discharge system to prevent any
contravention of surface water or groundwater standards. [ 15A NCAC 02T .1110]
2. The Permittee shall maintain an approved Operation and Maintenance Plan (O&M Plan)
Modifications to the O&M Plan shall be approved by the Division prior to utilization of the new plan.
The O&M Plan, at the minimum, shall include:

b. Maintenance schedules;
c. Inspection plan.;
d. Spill response plan;
e. Sampling and monitoring plan including the following information:
i. Names and/or titles of personnel responsible for conducting the sampling and monitoring;
ii. Detailed description of monitoring procedures including parameters to be monitored;
WQ0013276 Version 4.0 Shell Version 150101 Page 4 of 12

iii. Sampling frequency and procedures to assure that representative samples are being
collected. Fluctuation in temperature, flow, and other operating conditions can affect the
quality of the residuals gathered during a particular sampling event. The sampling plan shall
account for any foreseen fluctuations in residuals quality and indicate the most limiting times
for residuals to meet pathogen and vector attraction reduction requirements (e.g. facilities that
land apply multiple times per year but have an annual sampling frequency, may need to
sample during winter months when pathogen reduction is most likely to be negatively
affected by cold temperatures). [15A NCAC 02T .1100]
3. Bulk residuals shall not be land applied under the following conditions:
a. If the residuals are likely to adversely affect a threatened or endangered species listed under
section 4 of the Endangered Species Act or its designated critical habitat;
b. If the application causes prolonged nuisance conditions;
c. If the land fails to assimilate the bulk residuals or the application causes the contravention of
surface water or groundwater standards;
d. If the land is flooded, frozen or snow-covered, or is otherwise in a condition such that runoff of
the residuals would occur;
e. Within the 100 -year flood elevation, unless the bulk residuals are injected or incorporated within
a 24-hour period following a residuals land application event;
f. During a measurable precipitation event (i.e., greater than 0,01 inch per hour), or within 24 hours
following a rainfall event of 0.5 inches or greater in a 24-hour period;
g. If the slope is greater than 10% for surface applied liquid residuals, or if the slope is greater than
18% for injected or incorporated bulk liquid residuals;
h. If the soil pH is not maintained at 6.0 or greater, unless sufficient amounts of lime are applied to
achieve a final soil pH of at least 6.0, or if an agronomist provides information indicating that the
pH of the soil, residuals and lime mixture is suitable for the specified crop. Any approved
variations to the acceptable soil pH (6.0) will be noted in this permit;
i. If the land does not have an established vegetative cover unless the residuals are incorporated or
injected within a 24-hour period following a residuals land application event. Any field that is in
a USDA no -till program shall be exempted from meeting this vegetative cover requirement;
j. If the vertical separation between the seasonal high water table and the depth of residuals
application is less than one foot;
k. If the vertical separation of bedrock and the depth of residuals application is less than one foot;
1. Application exceeds agronomic rates.
[15A NCAC 02T. 11091
4. A Utilization Agreement between the Permittee and the entity agreeing to accept and distribute
Econo-Grow shall be in place prior to distribution of the bulk residuals. The agreement shall specify
the agreeing entity's responsibilities. The Permittee or his designee and the person responsible for
application of the residuals shall sign the Utilization Agreement, which shall be considered expired
concurrent with the permit expiration date, and shall be renewed during the permit renewal process.
[15A NCAC 02T .0108(b)(1), 02T 1104]
5. At a minimum, the Utilization Agreement shall stipulate the following:
WQ0013276 Version 4.0 Shell Version 150101 Page 5 of 12

allowed under the conditions of this agreement. Land application of Econo-Grow is considered
the beneficial reuse of a waste under 15A NCAC 02T .1100, and has been deemed permitted
under 15A NCAC 02T .1103(4) provided the conditions of this agreement are met. Any action
resulting in damages to surface water or groundwater, caused by failure to follow the conditions
of this agreement, is subject to Division enforcement action;
b. The person or entity accepting Econo-Grow shall to the best of their knowledge meet the
following application requirements:
i. List all prohibitions under Condition III.3 with a statement that bulk residuals shall not be
land applied under these conditions.
ii. Econo-Grow shall not be stockpiled for more than 14 days unless covered;

residuals are being applied.
[15A NCAC 02T .0108(b)(1), 02T 1104]
6. Econo-Grow shall be adequately stored to prevent untreated leachate runoff. The finished product
may be placed on a concrete pad, placed under shelter or physically covered until it is distributed to
the buyer. If an alternate storage site is used, approval must be obtained from the Division. [ISA
NCAC 02T .0108(b)(1)]
7. A label shall be affixed to the bag or other container in which residuals are sold or given away for
land application, or an information sheet shall be provided to the person who receives Class A
residuals. At a minimum, the label or information sheet shall contain the following:
a. The name and address of the person who prepared the residuals;
b. A statement that residual land application is prohibited except in accordance with the instructions
on the label or information sheet;
A statement identifying that this material shall be prevented from entering any public or private
water supply source (including wells) and any surface water (e.g., stream, lake, river, wetland,

8. The Permittee shall not distribute bulk residuals to any person or entity known to be applying
residuals contrary to the condition of the signed Utilization Agreement. [15A NCAC 02T .1103(a)]
9. This permit shall become voidable unless the agreements between the Permittee and the acceptor of
the residuals are in full force and effect. These agreements shall be considered expired concurrent
with the expiration date of the permit and shall be renewed prior to the initial distribution event of
that permit cycle event to that acceptor.
10. For fields receiving bulk residuals, the Permittee shall request of the landowner or lessee/operator a
statement detailing the volume of nutrient sources (waste residuals, manufactured fertilizers, manures,
or other animal waste products) other than the residuals to be applied by the Permittee, that have been
applied to the land, and a copy of the most recent Nutrient Management Plan (NMP), if available.
For the purpose of this permit condition, a Crop Management Plan (CMP), Waste Utilization Plan
(WUP) or Certified Nutrient Management Plan (CLAMP) shall also be considered a Nutrient
Management Plan
The NMPs must be provided only for those operations where a NMP (also CMP, WUP, or CNMP) is
required by the US Department of Agriculture — National Resources Conservation Service (MRCS) or
other State Agencies. The Permittee shall rely on the provided information to calculate appropriate
reductions in allowable nutrient loading rates. If the calculation shows that the agronomic rates
(including PAN) have already been met or exceeded on a field, no additional residuals shall be land
applied to that field.
11. Where the Permittee directly land applies bulk residuals to land, the Permittee shall supply the
landowner with documentation specifying that land application of the bulk residuals shall occur
consistent with this permit.
12. Where the Permittee distributes bulk residuals, the Permittee shall inform the receiver of the bulk
residuals of the Performance Standards and Operation and Maintenance Requirements specific to land
application of bulk residuals.
N. MONITORING AND REPORTING REQUIREMENTS
