To Whom It May Concern:
Enclosed are three copies of the 2020 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 Class A EQ heat -dried biosolids produced by NEFCO at the
processing facility in Quincy, Norfolk County, Massachusetts.
In October 2016 two more NEFCO plants were added to the permit— in West Palm Beach, FL and
Cumberland, MD. None of these plants shipped to NC during 2020. Therefore, a DMSDF Report Form
showing 0 tons shipped is included for each of them.
The attachments include analytical data of NEFCO's Class A EQ pellet biosolids during year 2020 for:
Baseline metals, nutrients and nitrogen. The monthly composite samples were analyzed by
Suburban Testing Labs, in Reading, PA
Fecal coliform. The monthly grab samples were analyzed by ESS Labs, in Cranston, RI
• TCLP. The annual composite sample was analyzed by ESS Labs, in Cranston, RI
During 2020 NEFCO-Quincy, MA shipped 92.49 tons of Class A EQ biosolids to the state of North
Carolina. The product was managed by 2 users:
Caines Brothers, in Chadburn, NC. The shipments were in May 2020, 3 trucks, total of 68.3 tons.
The product was used for an agricultural land -application.
Fred Fenimore -Camp Chemical Company, in Roxboro, NC. The shipment was in December 2020,
1 truck, 24.19 tons. The product was used for a fertilizer blending.

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.

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.

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.

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

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.

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.

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.

This is a monthly composite sample of Class A EQ Biosolids, fertilizer grade, collected at NEFCO
Plant, Quincy, MA.
Below are the parameters we need tested for:
- Please use Solid Materials Matrix for the testing. I checked the "Solid" matrix for the sample.
Please, test Total Solids via SM 2540-G, making sure you are certified Lab by NJ DEP and PA DEP for
this method.

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.

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.
REVIEWED
Laurel Stoddard By ESS Laboratory at 4:46 pm, Oct 06, 2020
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.

ESS Laboratory Work Order Number: 20J1045
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.

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.

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

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.
