Frequently Asked Questions
Q: What is ISO 14001 certification and why is it important for environmental management?
ISO 14001 is an international environmental management system standard that helps organizations identify and control their environmental impacts. ISO 14001 lead auditors evaluate facilities’ environmental management systems against the standard and help organizations implement continual improvement programs to reduce environmental risk and ensure regulatory compliance.
Q: What does an air permitting compliance audit involve?
An air permitting compliance audit examines whether a facility’s air emissions sources meet EPA and state air quality permit requirements. Auditors review permit conditions, emission monitoring data, control equipment maintenance, and operational procedures to ensure compliance with air quality regulations and identify opportunities for emission reductions.
Q: What is the difference between a safety compliance audit and an environmental compliance audit?
A safety compliance audit evaluates workplace hazards and OSHA regulatory compliance, while an environmental compliance audit assesses environmental management systems and EPA/state regulatory requirements for air, water, waste, and energy conservation. Many facilities like those in Kansas require both types of audits to address comprehensive EHS compliance.
Q: What qualifications should an EHS consultant have?
A qualified EHS consultant should hold industry certifications such as CSP (Certified Safety Professional) for safety matters and ISO 14001 Lead Auditor or CHMM (Certified Hazardous Materials Manager) credentials for environmental compliance. Advanced degrees in relevant fields like engineering or environmental science strengthen credentials for complex air, water, and waste management issues.
💰 Cost of air permitting mistakes: Missed construction permits on equipment changes: $10K–$100K+ in fines per day of non-compliance plus mandatory shutdown. Curtis’s expertise prevents those errors before they happen.
