LSRP Meaning & Requirements: The NJ Property Owner's Guide

What is an LSRP?

A Licensed Site Remediation Professional (LSRP) is a NJDEP-licensed environmental professional authorized under the Site Remediation Reform Act (SRRA) of 2009 to independently oversee the investigation and cleanup of contaminated sites in New Jersey. Before SRRA, every deliverable required case-by-case NJDEP review; the LSRP program transferred that authority — and professional liability — to licensed individuals so cases move faster.

When you're required to hire an LSRP

You are required to retain an LSRP any time a New Jersey property falls under the Site Remediation Program — the same regulatory track Envicon's NJ LSRP practice runs sites through. The most common triggers we see:

The SRRA process, milestone by milestone

SRRA imposes mandatory regulatory milestones. Miss them and the case can be pulled into NJDEP Direct Oversight — which typically doubles remediation cost and timeline. Here's the path an LSRP walks you through:

What an LSRP can do that a regular consultant cannot

• Issue Response Action Outcomes (RAOs) — case closure without waiting on NJDEP review.
• Sign remediation deliverables submitted to NJDEP under professional license and legal liability.
• Exercise professional judgment under N.J.A.C. 7:26E to select investigation and remedial approaches that fit the site.
• Interact with NJDEP directly on your behalf, including negotiating remedial action permits and institutional controls.

LSRP vs Phase I ESA — which do I need?

A Phase I ESA is a pre-transaction due-diligence screening under ASTM E1527-21 and can be performed by any qualified environmental professional. It answers "is there a recognized environmental condition here?" — see our Phase I / Phase II ESA services and the Phase I brownfield checklist for the scoping steps we follow.

An LSRP is required after contamination is confirmed and NJ remediation regulations are triggered. Envicon handles both in-house through our NJ LSRP services team — so if a Phase I turns up a REC that requires reporting, we hand off internally without you shopping for a second firm. For transaction-driven work, our brownfield remediation and UST closure practices cover the two most common LSRP-triggering scenarios.

How to choose an LSRP

• Active NJDEP license in good standing
• Experience with your specific case type (ISRA, UST, brownfield, Spill Act)
• In-house field, drilling, and lab-coordination capability
• Track record of RAOs issued in the last 24 months
• Transparent milestone-based fee structure, not open-ended hourly
