NJDEP Technical Requirements for Site Remediation

NJDEP Technical Requirements for Site Remediation

Site remediation involves identifying the source of contamination, determining the nature and extent of the contamination, and conducting the necessary cleanup work. It addresses a variety of problems that range from leaking underground oil tanks to widespread contamination. In most cases, the process involves removing the source of the contamination and decontaminating the soil and water to protect the health of humans and the environment.

Here is a summary of the technical requirements for site remediation issued by the New Jersey Department of Environmental Protection (NJDEP):

General Remediation Requirements

The general requirements for remediation include:

  • The person conducting the remediation must follow the NJDEP guidance. If there is any deviation from the guidance, a written rationale and justification for the change must be submitted.
  • All remediation work must be documented and included in the final report. The information provided must be site-specific, complete, accurate, and relevant.
  • Installations of borings and wells must be done according to the Well Construction and Maintenance, and Sealing of Abandoned Wells rules.
  • Remediation work in the Pinelands must be done in compliance with the provisions of the Pinelands Protection Act.


General Reporting Requirements

The general requirements for reporting include:

  • All required documents, spreadsheets, worksheets, and forms should be submitted to the NJDEP. The documents must be certified by a licensed site remediation professional.
  • A case inventory document worksheet (available on the department’s website) should be completed and submitted with each remedial phase work plan.
  • A quality assurance project plan should be prepared and submitted to the NJDEP with each remedial phase work plan.
  • A GIS-compatible site plan that shows the boundaries and location of the areas to be remediated should be submitted.


Immediate Environment Concern (IEC) Requirements

The requirements for immediate environmental concerns (IEC) include:

  • If any matter of immediate environmental concern (IEC) is identified, the person conducting the remediation must notify the case manager or call the department’s hotline number right away.
  • The impacts of IEC must be addressed within five days in the case of potable water IEC, and within 14 days in the case of vapor intrusion IEC. The form is available on the department’s website and must be completed and submitted within 14 days of the identification of IEC.
  • All IEC analytical results (with full laboratory data) must be submitted to the department within 14 days of the receipt of the data from the laboratory.
  • An engineered response action must be implemented within 60 days of the identification of an IEC. A report should also be submitted within 120 days of the IEC identification.
  • All sources of contamination contributing to the IEC must be identified within one year of identification.
  • Until a remedial action permit, as well as an NJDEP remedial action permit guidance, is received from the department, monitoring and maintenance reports detailing the oversight of contaminated properties and receptors must be submitted to the NJDEP annually.


Quality Assurance Requirements

The requirements for quality assurance include:

  • The laboratory or company involved in any laboratory or field activity must have all the applicable certifications, must be capable of performing the analysis and meeting the data quality objectives specified in the site. The lab or company must use analytical methods that have sufficiently accurate analytical sensitivity, perform sample matrix cleanup methods where necessary, and follow all quality assurance and quality control procedures specified in the site-specific Quality Assurance Project Plan (QAPP).
  • Free screening methods should not be used to verify a clean zone or identify contaminants. However, they may be used where 10 or more samples are required for initial characterization sampling.


Remedial Investigations Requirements

The requirements for remedial investigations include:

  • The person conducting the remediation must investigate when the concentration of any contaminant exceeds any remediation standard, such as the NJDEP soil remediation standard and/or the aquatic surface quality standard.
  • A remedial investigation work plan should be submitted to the NJDEP for approval.

The NJDEP guidance covers everything necessary to ensure site remediation is conducted in a manner that removes risks to the environment and the humans living in it.
