THE CHALLENGE
Why Environmental Compliance Demands Expert Support
Non-Compliance Means Fines, Shutdowns, and Liability
EPA violations can mean $10,000+ daily fines. State agencies can shut down operations for failed tank tests. Unreported releases create massive liability exposure. You can't afford reactive compliance - you need proactive management from experts who know the regulations.
Regulations Vary Significantly Across States
California requirements differ from Oregon. Montana has different timelines than Washington. Multi-state operators face a patchwork of regulations with different testing frequencies, reporting requirements, and enforcement approaches. You need a partner who knows each state's specific requirements.
Contamination Problems Escalate Quickly and Expensively
A small release ignored becomes a million-dollar remediation project. What starts as a failed tank test can evolve into years of groundwater monitoring. Early detection and proper response prevents small problems from becoming major liabilities.
