Tank Closure & Decommissioning
Why choose us

What sets our tank closure & decommissioning apart.

  • 01

    Closure done right the first time

    An incomplete closure is an active liability. We follow NYSDEC, Suffolk County SCDHS, Nassau County NCDH, Westchester WCDOH, and Virginia DEQ closure protocols precisely — soil sampling endpoints, closure reports, and deregistration filings all on file.

  • 02

    Real estate transactions cleaned up

    Tanks discovered during a Phase I ESA can hold up a closing for months. We move quickly to assess, scope, and close out tank issues so transactions stay on schedule.

  • 03

    Heating oil tanks too

    Residential and commercial heating oil tanks — both UST and AST — are a common source of compliance surprises. We close them properly, sample the soil, and document the work for buyers, sellers, and lenders.

Our process

How we work.

  1. STEP 01

    Closure assessment

    We review tank construction, age, contents, regulatory status, and surrounding site conditions to determine whether tank removal or in-place closure is appropriate.

  2. STEP 02

    Regulatory notification

    We notify the appropriate authority (NYSDEC, county health department, VA DEQ) before closure begins, ensuring the work is observed and documented as required.

  3. STEP 03

    Closure execution & sampling

    We coordinate the field work — tank cleaning, removal or in-place fill, soil sampling at required endpoints — and document everything for the closure report.

  4. STEP 04

    Closure report & deregistration

    We deliver a complete closure report to the regulatory authority, file deregistration with NYSDEC PBS or equivalent, and provide you the close-out documentation that buyers, lenders, and insurers will want to see.

Common questions

About tank closure & decommissioning.

Do I have to remove the tank or can I close it in place?

It depends on tank type, location, contents, and the regulatory authority. USTs in NY are typically removed; some heating-oil USTs can be closed in place if removal is impractical. We assess and recommend the appropriate closure method for your specific situation.

What does a closure report include?

Site description, tank construction and history, closure method, soil sample results against applicable cleanup standards, photographic documentation, and any release reporting if contamination is found. The report is filed with the regulatory authority and becomes part of your permanent property file.

What if soil samples come back contaminated?

If we discover a release during closure, we report it to the regulatory authority within the required timeframe and develop a corrective action plan. In Virginia, eligible heating oil releases can be reimbursed through the Virginia Petroleum Storage Tank Fund (VPSTF). We'll guide you through the process.
