Task 4 – Remedial Action Permit Scope of Work Either Task 4A or Task 4B will be completed, depending on the outcome of the groundwater sampling conducted under Task 2. Task 4A – Termination of Groundwater Remedial Action Permit If the results of the groundwater sampling event (Task 2) indicate that benzene is below the applicable GWQS for a second consecutive sampling event, then the remedial action objectives have been achieved. Matrix will prepare the termination of the groundwater RAP. This task will include a detailed review of the existing permit and compliance documentation, evaluation of the groundwater data trends, and confirmation that all permit obligations have been satisfied. Since there was a change in Site Ownership and responsible party has occurred, a RAP Modification Request will be prepared and submitted to the NJDEP. Once the Township has been added to the Groundwater RAP, a complete RAP Termination request package will be prepared, including the NJDEP termination form, supporting data tables, figures and justification summary. The termination request will be submitted through the NJDEP portal/email. Task 4B – Biennial Certification of Groundwater Remedial Action Permit If the results of the groundwater sampling event (Task 2) indicate that benzene is above the applicable GWQS, then continued monitoring is required. Matrix will prepare a biennial certification of the groundwater RAP in accordance with NJDEP requirements. Prior to preparing the biennial certification, a RAP modification request will be prepared and submitted to the NJDEP as the property ownership and responsible party has changed and is now the Township. Once the RAP modification is approved by the NJDEP and the Township is added to the Groundwater RAP, Matrix will review and evaluation of all monitoring data collected since the previous certification, preparation of updated data tables and figures, and completion of the NJDEP Biennial Certification form. The certification package will include a narrative summary of remedial progress, discussion of contaminant trends, and confirmation of ongoing compliance with permit conditions. The completed package will be submitted through NJDEP portal/email. Task 5 – Well Decommissioning If NJDEP approves termination of the groundwater RAP (Task 4A), all ten (10) monitoring wells associated with the Site will be properly decommissioned

NJDEP portal/email. Task 5 – Well Decommissioning If NJDEP approves termination of the groundwater RAP (Task 4A), all ten (10) monitoring wells associated with the Site will be properly decommissioned in accordance with NJDEP Well Construction and Maintenance; Sealing of Abandoned Wells regulations (N.J.A.C. 7:9D). This task will include the oversight of a well driller preparing and submitting the required Well Decommissioning Permit applications to NJDEP, coordination with a licensed New Jersey well driller, and oversight of the completion of well abandonment activities following approved methods to prevent vertical migration of groundwater. Task 6 – Issuance of Remedial Action Outcomes Upon NJDEP’s approval of the Groundwater RAP Termination (Task 4A) and completion of all well decommissioning activities (Task 5), the LSRP will prepare and issue the final unrestricted use Area of Concern (AOCs) Remedial Action Outcomes (RAOs). This task will include preparation of the RAO document(s), supporting figures, and summaries of remedial actions completed at the site in accordance with N.J.A.C. 7:26C-6.2. The RAOs will certify that all remedial actions have been conducted in compliance with NJDEP Technical Requirements for Site Remediation (N.J.A.C. 7:26E) and that the site now meets the applicable remediation standards for unrestricted use. The completed RAO package s will be submitted through NJDEP Online, and copies will be provided to the client for their permanent records, signifying full regulatory closure of the Site. Task 7 – LSRP Oversight and Project Management The LSRP of record will oversee the activities outlined above. This task includes costs for Matrix to communicate with the NJDEP and client through in person meetings or conference calls.
