AIR QUALITY ENGINEER JOB DESCRIPTION

Air quality permitting is a technical discipline with real legal exposure. A missed Title V renewal, a flawed Prevention of Significant Deterioration analysis, or an unresolved notice of violation can halt construction on a capital project worth tens of millions of dollars. The Air Quality Engineer is the practitioner who prevents that outcome, preparing permit applications, conducting dispersion modeling, and keeping client facilities in continuous compliance with state and federal regulators under the Clean Air Act. This role requires independent technical judgment across a diverse project portfolio. Clients span the petrochemical, manufacturing, and energy sectors, each governed by distinct NESHAP and NSR obligations.

As the Air Quality Engineer, you will prepare and defend permit applications under Title V, NSR, and PSD frameworks for industrial clients navigating federal and state Clean Air Act compliance, while also contributing to business development and proposal writing within an environmental consulting practice. You will work under the direction of senior engineers or a project manager, managing your own deliverables across multiple simultaneous client engagements in an office and field environment.

Career Impact: Consulting exposure across petrochemical, manufacturing, and energy clients accelerates regulatory knowledge faster than a single-industry in-house role, and EIT or PE licensure earned here becomes a marketable credential with lasting weight in the air quality field.

Business Impact: Industrial clients depend on timely, technically defensible permit packages to keep construction schedules and capital projects moving; the work this engineer produces directly determines whether a facility meets its regulatory milestones on time.

Growth Opportunity: The scope path is clear: strong technical delivery opens project management responsibility and, for those who develop client relationships, a role in business development and senior technical leadership within the consulting practice.

• Prepare permit applications for Title V operating permits, NSR, and PSD projects serving petrochemical, manufacturing, and energy sector clients.
• Conduct air dispersion modeling and meteorological data processing to support permit applications and impact assessments.
• Calculate air contaminant emissions for stationary and mobile sources, including greenhouse gas inventories and annual compliance reporting.
• Evaluate regulatory applicability under NESHAP, MACT, BACT, and LAER for new and modified emission sources.
• Review and assess compliance methodologies at client facilities, identifying gaps and recommending corrective approaches.
• Write technical reports presenting modeling methodology, results, and regulatory recommendations for client and agency audiences.
• Support site inspections, source testing scope development, and field monitoring as required by the project scope.
• Assist with proposal preparation, including scope development and cost estimation for new and existing client opportunities.

• Bachelor's degree in Chemical Engineering, Environmental Engineering, Environmental Science, or a related discipline, or equivalent work experience.
• Two or more years of air quality permitting and compliance experience, with demonstrated familiarity with Title V, NSR, or NESHAP programs.
• Working knowledge of federal Clean Air Act regulations, including Prevention of Significant Deterioration, new source review, and major source threshold determinations.
• Demonstrated ability to perform emissions calculations using established methodologies such as AP-42 emission factors and engineering-based estimation.
• Strong technical writing skills, with experience preparing regulatory documents, compliance reports, or permit applications.
• Ability to manage multiple project assignments concurrently while meeting client deadlines and budget constraints.
• Willingness to travel to client facilities for site visits, source testing, and field data collection as project needs require.
• Effective oral and written communication skills for direct client and regulatory agency interaction.

EIT certification or active pursuit of Professional Engineering licensure in the state(s) of primary practice

Demonstrated experience with air quality impact assessments under CEQA, NEPA, or state environmental review programs

Knowledge of greenhouse gas quantification methodologies, including Toxic Release Inventory reporting and National Pollutant Release Inventory submissions

Regional regulatory experience with state-specific programs, such as TCEQ air permitting requirements or Florida-specific NSR requirements

• Permit application acceptance rate, measuring how often submitted packages proceed without agency rejection, requiring a major revision.
• Number of active client projects managed concurrently, reflecting workload capacity and project coordination.
• Compliance report on-time delivery rate, tracking adherence to regulatory submission deadlines across the managed portfolio.
• Dispersion modeling accuracy rate, measured by the proportion of modeling analyses that pass agency technical review without resubmission.
• Client repeat engagement rate, indicating whether technical delivery generates follow-on project awards from existing clients.
• Typical tools: dispersion modeling software (commonly AERMOD or CALPUFF); emissions estimation platforms (commonly E&P Tanks or MOVES)

• Base Salary Range: $70,000 to $100,000 annually, depending on experience and location
• Bonus: Annual performance bonus, typically 5 to 10 percent of base salary
• Equity: Generally not offered at the individual contributor level in consulting
• Health Benefits: Medical, dental, and vision coverage; employer contributes the majority of the premium
• PTO: 15 to 20 days annually, plus federal holidays
• Common Perks: Professional licensure exam reimbursement, conference attendance support, mileage reimbursement for client travel
