The Situation

When a 6,000-gallon underground storage tank beneath a commercial office property in Indiana began releasing heating oil, the signs were hard to ignore. Oil pooled at the main entrance. Strong petroleum vapors spread through the building, affecting employees and visitors. The tank — a heating oil UST that had been in place for years — was located beneath an intricate network of concrete and limestone infrastructure, making access difficult and urgency unavoidable.

With the building still actively occupied, the property owner faced overlapping concerns: potential soil and groundwater contamination, imminent regulatory scrutiny from Indiana environmental authorities, and the threat of escalating environmental liability. Every day without a response was a day the situation could worsen.

What the property owner needed was a team capable of commercial UST remediation in Indiana — one that could respond immediately, handle every phase of the work, and carry the project through to formal regulatory closure. That’s what Aegis Environmental was built to deliver.

The Results

The outcome was unambiguous.

The state issued a formal No Further Action (NFA) determination — the regulatory equivalent of a clean bill of health for the property. That determination confirmed:

• • • The source of contamination was fully removed
    • All analytical results came back below regulatory screening levels
    • No ongoing environmental risk was identified at the site
    • All materials were disposed of at properly permitted facilities

An NFA determination doesn’t happen by accident. It is the result of thorough site assessment, targeted remediation, rigorous documentation, and effective regulatory communication — every element of which Aegis managed from start to finish.

What This Meant for the Client

For the property owner, the NFA determination wasn’t just a technical milestone. It was a business outcome.

• • • Environmental liability eliminated. The contamination that threatened to become an open-ended legal and financial exposure was fully addressed and officially closed.
    • Extended regulatory oversight avoided. Many contaminated sites remain under state monitoring programs for years — sometimes decades. By achieving thorough cleanup and an NFA determination, this property owner was not enrolled in any ongoing oversight program.
    • Property value and usability preserved. A commercial property with unresolved environmental issues is a difficult asset to manage, lease, sell, or refinance. With closure in hand, the property’s value and operational viability were protected.
    • Efficient resolution. From discovery to closure, the project was managed with focus and precision — delivering the best achievable result without unnecessary delay or scope.
