An LSRP is an environmental professional licensed by the New Jersey Department of Environmental Protection (NJDEP) to oversee site investigations and cleanups. The LSRP is responsible for ensuring compliance with NJDEP regulations and issues the final Response Action Outcome (RAO) letter when remediation is complete.

You are required to hire an LSRP if you own or are responsible for a commercial or industrial property in New Jersey that has confirmed or suspected contamination. Common triggers include:

• Leaks from commercial underground storage tanks

• Contaminated soil, groundwater, or vapor intrusion

• NJDEP directive or case number assignment

You do not need an LSRP for:

• Residential heating oil tanks used for onsite heating

• Environmental due diligence (Phase I, Phase II, or Preliminary Assessments)

An LSRP:

1. Conducts a Preliminary Assessment and Site Investigation.

2. Designs and oversees the Remedial Investigation (soil, groundwater, vapor testing).

3. Prepares a Remedial Action Workplan and manages cleanup activities.

4. Submits all findings and progress reports directly to the NJDEP.

5. Issues a Response Action Outcome (RAO) when the case is closed.

Oak Environmental’s LSRPs ensure every report is lender-ready, attorney-defensible, and fully NJDEP-compliant.

Sometimes, yes. Many real estate transactions proceed if a formal remediation plan is in place under an LSRP’s oversight. However, buyers and lenders typically require documentation proving active NJDEP compliance. Oak Environmental provides clear status reports to support deals and prevent last-minute surprises.

Timelines vary based on contamination severity:

• Simple cases: a few months, if limited soil removal is required.

• Complex cases: one to several years, if groundwater or vapor intrusion is involved.

Oak Environmental provides a clear project roadmap and timeline, so clients know what to expect.

Failing to comply with NJDEP requirements can result in:

• Significant fines and penalties

• Environmental liens placed on the property

• Inability to sell, refinance, or redevelop the property

Hiring an LSRP ensures compliance, protects property value, and avoids long-term liability.

Costs depend on property size, site history, and the extent of contamination. While some projects may only involve investigation, others require years of monitoring and remediation. Oak Environmental provides transparent proposals upfront, so clients understand costs before work begins.

An RAO is the final compliance document issued by an LSRP confirming that a site meets all NJDEP remediation requirements. It replaces the old NJDEP “No Further Action (NFA) letter” and serves as the official clearance for property transactions, refinancing, or redevelopment.

• Deliver defensible, lender-accepted reports
