Senior Air Pollution Auditor

Most weeks involve leading emissions audits, mentoring junior auditors, and engaging with environmental and operations leadership. You'll often own complex Title V or NSR/PSD permit compliance reviews, lead emission inventory and CEMS data audits, support agency inspections or enforcement defense, and contribute to environmental management system improvements. The work requires familiarity with EPA regulations, state-level requirements, and industry-specific emission factors.

What's harder than people expect is the regulatory complexity — Clean Air Act regulation involves federal rules, state implementation plans, and industry-specific MACT or NSPS standards that all interlock. Variance is significant between corporate environmental audit (deep familiarity with one industry), public accounting environmental practice or specialized consulting (multi-client work), and regulatory agency work (EPA, state environmental agencies). Professional Engineer or Certified Environmental Auditor credentials shape advancement.

People who tend to thrive here are technically rigorous, comfortable with environmental regulation, and credible to both operations and regulator audiences. If you want generalist financial audit, the niche focus can constrain. If you find satisfaction in owning the integrity of environmental compliance in regulated industries, the work tends to be increasingly in demand and a strong path into senior environmental leadership or specialized consulting.
