Emission Analyst

Primary purpose

Perform emissions compliance testing, analysis, documentation, and reporting for Tallgrass equipment in accordance with applicable state and federal regulations and air permits. Provide equipment performance evaluation, troubleshooting, modeling, and tuning necessary to achieve and sustain compliant operation. This role is assigned to the Air Compliance organization and partners closely with Field Operations, Maintenance, Engineering, and third-party vendors.

Essential duties and responsibilities

Emissions Compliance Testing, Documentation & Reporting

* Perform emissions testing and monitoring to support required engine/turbine testing programs using specialized instruments and software.

* Set up, operate, calibrate, and maintain equipment such as electronic manometers, exhaust gas analyzers, portable emissions analyzers, and other sampling/testing equipment.

* Record, validate, and document emissions levels for applicable criteria pollutants.

* Schedule, coordinate, track, and document required emissions testing to meet permit and regulatory deadlines.

* Coordinate with Field Operations and Air Compliance to set test dates/times within required timelines.

* Utilize tracking systems to monitor runtime and testing frequency for permit-required emission sources.

* Prepare, maintain, and distribute emissions monitoring reports and other regulatory-required records used to demonstrate compliance.

* Interpret air quality permit requirements for each assigned facility; maintain advanced knowledge of state and federal testing regulatory requirements and protocols (including NSPS Subparts IIII, JJJJ, KKKK; NESHAP Subparts ZZZZ and HH; EPA Reference Methods; and state air permitting requirements.

* Notify Air Compliance leadership in a timely manner of emissions exceedances or compliance risks; support internal/external reporting and regulatory interactions as directed.

* Assist with inspections and information requests from state/local/federal agencies as directed by Air Compliance.

Mechanical Performance & Diagnostics

* Perform routine performance evaluation and troubleshooting of engines, turbines, motors, compressors, pumps, and drivers to support compliant operation and valid emissions test results.

* Conduct exhaust analysis and reporting; provide technical recommendations to improve emissions performance and operational stability.

* Tune engines (including Caterpillar, Waukesha, and Superior where applicable) to achieve required emissions levels; document settings/results and required follow-up actions.

* Apply engine and compressor modeling to establish, validate, or correct performance and control system accuracy impacting emissions outcomes.

* Perform problem determination and resolution through troubleshooting, root cause analysis, and technical reporting, including recommended corrective actions (repairs, adjustments, component replacement, controls changes, operational changes, and/or re-testing).

* Use diagnostic/predictive tools as needed to support mechanical health evaluation and compliance outcomes (e.g., vibration testing/data analysis, ultrasonic leak detection and quantification, portable emissions testing and modeling).

* Communicate equipment mechanical health and compliance-impacting conditions to Field Operations, Air Compliance, and local/regional management.

Vendor Oversight, Commissioning Support & General Requirements

* Coordinate and oversee third-party emissions testing/analysis/reporting; review deliverables for completeness, quality, and alignment with permit/testing requirements.

* Coordinate needed adjustments, repairs, replacements, or re-testing of emissions sources or control equipment with Field Operations, Maintenance, and vendors.

* Support commissioning/start-up of new, modified, or replacement equipment to ensure proper setup, controls accuracy, and compliant operation.

* Perform internal facility assessments as needed to verify compliance with air permitting requirements.

* Perform all work in compliance with company standards, procedures, safety requirements, and applicable regulatory/tariff requirements.

* Maintain dependable attendance; work non-traditional hours…
