Tank Closure & Removal Assessment

Independent Pre-Closure Assessment Under EPA 40 CFR §280.71

USTEX provides independent pre-closure tank assessment and site characterization under EPA 40 CFR §280.71 and Wisconsin ATCP 93. Our conflict-free model means closure findings are objective — we have no financial interest in the remediation that may follow.
