As such, these documents are available for inspection and examination by any person upon request (NC General Statute 132-6). Instructions: Prepare one form for each individually monitored unit. Please type or print legibly. Attach a notification table with values that attain or exceed NC 2L groundwater standards or NC 2B surface water standards. The notification must include a preliminary analysis of the cause and significance of each value. (e.g. naturally occurring, off-site source, pre-existing condition, etc.). Attach a notification table of any groundwater or surface water values that equal or exceed the reporting limits. Attach a notification table of any methane gas values that attain or exceed explosive gas levels. This includes any structures on or nearby the facility (NCAC 13B .1629 (4)(a)(i). Send the original signed and sealed form, any tables, and Electronic Data Deliverable to: Compliance Unit, NCDENR-DWM, Solid Waste Section, 1646 Mail Service Center, Raleigh, NC 27699-1646. Solid Waste Monitoring Data Submittal Information Name of entity submitting data (laboratory, consultant, facility owner): Contact for questions about data formatting. Include data preparer's name, telephone number and E-mail address: Name: Phone: E-mail: Facility name: Facility Address: Facility Permit # NC Landfill Rule: (.0500 or .1600) Actual sampling dates (e.g., October 20-24, 2006) Environmental Status: (Check all that apply) Initial/Background Monitoring Detection Monitoring Assessment Monitoring Corrective Action Type of data submitted: (Check all that apply) Groundwater monitoring data from monitoring wells Methane gas monitoring data Groundwater monitoring data from private water supply wells Corrective action data (specify) Leachate monitoring data Other(specify) Surface water monitoring data Notification attached? No. No groundwater or surface water standards were exceeded. Yes, a notification of values exceeding a groundwater or surface water standard is attached. It includes a list of groundwater and surface water monitoring points, dates, analytical values, NC 2L groundwater standard, NC 2B surface water standard or NC Solid Waste GWPS and preliminary analysis of the cause and significance of any concentration. Yes, a notification of values exceeding an explosive methane gas limit is attached. It includes the methane monitoring points, dates, sample values and explosive methane gas limits. Certification To the best of my knowledge, the information reported and statements made on this data submittal and attachments are true and correct. Furthermore, I have attached complete notification of any sampling values meeting or exceeding groundwater standards or explosive gas levels, and a preliminary analysis of the cause and significance of concentrations exceeding groundwater standards. I am aware that there are significant penalties for making any false statement, representation, or certification including the possibility of a fine and imprisonment.

Boylan Avenue Raleigh, NC, 27603 Ref: Analytical Testing Lab Report Number: 23-263-0002 Client Project Description: North Carolina Landfills - Northampton F Site: 66-01 Dear Seth C. Rickerts: Waypoint Analytical, LLC (Charlotte) received sample(s) on 9/19/2023 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. 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 were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) 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.

The centrifuged aqueous sample was decanted back into the original sample bottle,off of the condensed solids remaining in the centrifuge bottle.Original sample bottle was rinsed as normal and centrifuge bottle was rinsed with 4mL of 1%Amm-MeOH.Centrifuge bottle rinsate was added to the elution.Samples concentrated to <5mL. Surrogate recovery for the following sample was outside the upper control limit:YI18004-002. This sample did not contain any target analytes;therefore,re-extraction and/or re-analysis was not performed. The following samples were diluted due to the nature of the sample matrix:YI18004-004, YI18004-005,YI18004-007,YI18004-010.The LOQ has been elevated to reflect the dilution.

For sample YI18004-002 sample matrix prevented full volume from being extracted,precluding method mandated bottle rinse.Elution solvent was aliquoted directly into the reservoir,rinsing the inside.Surrogate recovery may be adversely affected.
