Nikki has conducted over 80 environmental audits at industrial facilities. She is also an ISO 14001 Certified Lead Auditor. In this presentation, Nikki identifies the most common environmental gaps and trouble points she’s observed in the areas of waste, water, air and overall compliance.

TL;DR: Nikki Chavez’s 80+ audits reveal consistent gaps: waste handling/documentation errors, wastewater discharge violations, air emissions exceeding permit limits, and incomplete EHS management system documentation. These gaps cross industries and facility sizes, indicating systemic compliance blind spots that audits rapidly expose and that written corrective action plans can close.

What’s at Risk: Unaudited facilities accumulate compliance gaps silently until an EPA inspection triggers enforcement. Single audit findings can spawn multiple citations, fines, and operational restrictions. Facilities with documented audit histories and corrective action tracking typically negotiate lighter enforcement and demonstrate due diligence to insurance carriers and regulators.

Frequently Asked Questions

Q: What are the most common environmental compliance gaps found in audits?

Common environmental compliance issues include improper waste handling and documentation, wastewater discharge violations, air emissions exceeding permit limits, and incomplete environmental management system documentation. iSi Environmental’s data from over 80 environmental audits shows these gaps consistently across industrial facilities.

Q: What is a CHMM certification and why is it important for environmental audits?

CHMM stands for Certified Hazardous Materials Manager, a professional credential demonstrating expertise in hazardous waste management, environmental regulations, and compliance strategies. Auditors with CHMM certification provide authoritative assessments of facility environmental programs and help identify risk areas.

Q: What does an environmental audit cover?

Environmental audits assess compliance across four primary areas: waste management, water discharge, air emissions, and overall EPA compliance. iSi Environmental conducts comprehensive audits that evaluate whether facilities meet federal EPA regulations and state-specific environmental requirements.

Q: How often should facilities conduct environmental audits?

While no universal frequency mandate exists, most facilities benefit from environmental audits every 2-3 years to ensure ongoing EPA compliance and identify emerging regulatory changes. Industrial facilities in Chattanooga and the surrounding regions should consider annual audits if they operate under multiple EPA permits or have significant environmental risks.


Environmental audits start at $1,500 for records review and single-system assessment (waste, water, or air). Comprehensive facility audits covering waste, water, air, and management systems run $3,500–$8,000 depending on facility size and operational complexity.
