Frequently asked questions: Northern New Jersey
What does a Phase 1 ESA cost in Northern New Jersey?
New Jersey carries one of the largest state premiums in published cost guides, about 30% above the national baseline, putting a typical Northern New Jersey commercial parcel around $2,600 to $5,850.
Why does Northern New Jersey need heavier environmental due diligence?
The region's industrial corridor along the Turnpike and Newark Bay has one of the country's densest concentrations of historically regulated sites, which means more records for a consultant to review even before the site visit.
Does New Jersey's own state environmental program replace the Phase 1 ESA?
No. New Jersey runs its own site-remediation program through the state Department of Environmental Protection, but that's separate from the federal AAI process. A Phase 1 ESA to the ASTM E1527-21 standard is still what a buyer needs for CERCLA liability protection.
