Environmental Specialist, Air Quality

About the role

Crusoe is seeking an Environmental Specialist, Air Quality to join our growing Health, Safety, and Environment (HSE) team.

Responsibilities

• Air Permitting Support: Assist senior staff in advancing air permit applications across multiple simultaneous campaigns, including New Source Review (NSR), Prevention of Significant Deterioration (PSD), and minor/synthetic minor permit applications with the TCEQ and other state agencies. Support Permit by Rule (PBR) registrations and Standard Permit authorizations, respond to Notices of Deficiency (NODs), and track permit status and milestone schedules.
• Air Compliance: Support ongoing compliance obligations under Title V operating permits, NSPS, and NESHAP standards. Monitor compliance schedules for operational limitations, testing requirements, and reporting deadlines; assist with periodic compliance certifications, deviation reports, and annual emissions inventory submittals; and support stack testing coordination and NSPS Subpart IIII, KKKK, KKKKa and NESHAP Subpart ZZZZ applicability determinations.
• Emissions Calculations & Inventory: Perform and QC emissions calculations in support of permit applications and annual state reporting. Calculate potential-to-emit (PTE) and actual emissions using EPA AP-42 emission factors, CEMS data, and vendor-supplied performance data.
• Regulatory Research & Agency Interaction: Stay current on federal and state air quality regulations relevant to Crusoe's operating fleet. Support drafting of routine regulatory agency correspondence and support preparation for TCEQ inspections and audits, including records compilation and site readiness.
• Documentation & Compliance Tracking: Maintain highly organized and audit-ready compliance documentation. Support management of compliance calendars, permit condition trackers, and testing/reporting logs; support development and maintenance of standardized recordkeeping templates and SOPs as the program scales; and support EHS information system implementation.
• Process analysis & Optimization: Map and evaluate existing environmental processes to identify automation opportunities, bottlenecks, and data gaps; recommend AI-assisted improvements that reduce manual burden while maintaining regulatory defensibility.
• Cross-Functional Collaboration: Partner with Field Operations to communicate permit conditions, operational limits, and monitoring requirements to site personnel. Work closely with project development and construction teams to identify air permitting needs early in the site lifecycle, and develop environmental training materials related to air compliance.

• Education: Bachelor's degree in Environmental Science, Environmental Engineering, Atmospheric Science, or a related scientific/technical field is preferred (equivalent field experience is also welcome).
• Experience: 1–5 years of dedicated air quality compliance or permitting experience.
• Knowledge: Foundational to working knowledge of NSR/minor permitting, Title V operating permits, and/or PBR and Standard Permit mechanisms. Familiarity with TCEQ permitting processes is highly preferred.
• Regulations: Working familiarity with NSPS and NESHAP applicability for stationary engines or combustion sources (specifically Subparts IIII, KKKK, and ZZZZ), with the ability to interpret 40 CFR requirements with guidance.
• Calculations: Working familiarity with emissions calculations (AP-42 factors, vendor performance data, CEMS) and calculations of potential-to-emit (PTE), pollutant-specific GWPs, and general unit conversions.
• Communication & Technical Writing: Excellent written communication skills, with the ability to draft technical summaries, permit narrative sections, and agency correspondence with senior review.
• Computer & Systems Skills: Advanced proficiency in Microsoft Excel for emissions calculations and data management. Comfort with or willingness to master TCEQ STEERS/DART, EPA CEDRI, and EHS compliance tracking tools.
• Travel: Willingness and ability to travel 25–35% for site visits, inspections, and agency meetings as required.
