Closure Corner
Proven Pathways to Site Closure
At Elkhorn Environmental, we don’t just investigate contamination, we close sites.
Closure Corner highlights our track record of successfully navigating complex environmental sites to regulatory closure.
How We Get to Closure
A Closure-First Method
Closure is a sequence, not an accident. We run every site through the same disciplined path from day one.
01
Define the goal
Identify the closure standard and end use first, so every dollar of investigation points toward it.
02
Right-size the work
Scope investigation and cleanup to meet that standard, no more and no less, using risk-based reasoning.
03
Engage the regulator
Bring the overseeing agency in early to align on the path, before assumptions become disputes.
04
Document & close
Assemble the defensible record that earns a No Further Action determination and protects it long-term.
Closure Track Record
Representative Closures
A snapshot of the kinds of complex sites we have guided to regulatory sign-off.
Former Dry Cleaner
Retail Redevelopment, North Bay
Chlorinated-solvent impacts in soil and groundwater stood between a retail parcel and its sale. We scoped a focused investigation and risk-based closure strategy.
Closed - No Further Action achieved
Fueling Station
Underground Storage Tank Case
A long-open petroleum UST case carried ongoing monitoring costs. We demonstrated stable, attenuating conditions and built the case for low-threat closure.
Closed - Case closure granted
Industrial Parcel
Vapor Intrusion Evaluation
Vapor-intrusion concerns threatened a planned reuse. Targeted soil-vapor data and a defensible risk evaluation cleared the path for redevelopment.
Closed - Reuse approved
Representative examples shown for illustration. Specific project details available on request.
Our Approach
Our Closure Philosophy
We approach every site with closure in mind from the beginning, not as an afterthought.
What We Avoid
- Open-ended investigation with no end point
- Data collected without a decision attached
- Surprises that derail transactions or schedules
What We Deliver
- A clear, defensible path to closure
- Regulator alignment from the start
- A documented record that holds up over time
