A Preliminary Assessment (PA) checks the history of a property to see if there may have been spills, leaks, or other risks in the past.

You may need one if you're buying, selling, leasing, or developing commercial property in NJ —especially if the property is in the NJDEP Site Remediation Program or connected to Green Acres or ISRA.

A PA helps you meet NJDEP rules. It shows whether the site is clean—or if more testing is needed before you move forward.

We look at old records, permits, maps, and past uses. Then we walk the property to check for signs of contamination.

No. A PA is about research and site inspection. If we find red flags, we may recommend a Site Investigation with testing next.

An AOC is a spot on the property that has an identified concern —like a tank, loading dock, or chemical storage area.

Most Preliminary Assessments take 3 to 6 weeks. We work fast to help you meet deadlines and avoid project delays.

No —a No Further Action letter is specifically for residential home heating oil tank releases that have been cleaned up.

If a PA leads to a Site Investigation and no additional work is needed, then a LSRP can issue a Remedial Action Outcome, if needed.

No. If a PA is being completed for environmental due diligence, a LSRP is not needed.

If you’re already in the NJDEP Site Remediation Program, it’s smart to have an LSRP lead the process and keep everything compliant.

We know NJDEP rules inside and out. Our team gives you clear answers, fast reports, and a solid plan if more steps are needed.
