Air Quality Consultant –India GDC (Gurgaon)

Role summary

Support North America permitting and regulatory reporting programs via desktop-based workflows for industrial, energy, pharmaceutical, technology, and chemical sector clients, producing regulator-ready calculations, documentation, and submissions under the US Clean Air Act and state programs with mentoring and QA/QC from senior reviewers.

Core responsibilities

Permitting support

• Draft permit application content for Title V operating permits, state construction permits, and minor/major NSR/PSD, including process/equipment descriptions, emissions calculations, monitoring and recordkeeping plans, and applicability matrices referencing NSPS and NESHAP/MACT where relevant, ensuring state-specific forms and attachments are complete and aligned with guidance such as NJDEP requirements where applicable.
• Coordinate inputs for dispersion modeling with senior modelers, prepare input data packages (stack parameters, release types), and maintain crosswalks linking model assumptions to application narratives and response-to-comment drafts for reviewer use, ensuring NA regulatory scope.
• Conduct desktop control-technology research from public determinations and vendor literature to support preliminary BACT/LAER writeups for junior and senior reviewer refinement, keeping citations and change logs up to date per team SOPs.

Regulatory reporting

• Build traceable emissions inventories and reporting workpapers using client activity data, approved emission factors, and calculation templates, producing state annual emission statements, AERR inputs, Title V compliance/periodic reports, MACT/NESHAP periodic reports, and deviation logs as required for NA programs, with clear QA/QC checks and version control.
• Support EPCRA Tier II and TRI Form R/NA preparation by performing chemical thresholding, de minimis and mixture evaluations, SDS data extraction, and unit/stoichiometry conversions with senior oversight, documenting assumptions and data lineage clearly for audit readiness as emphasized by the SME JD.
• Reconcile permit, criteria/HAP, and GHG datasets to ensure consistency across submissions and client internal records, preparing evidence folders suitable for agency or client audits within NA jurisdictions, and flagging inconsistencies early for senior review and resolution.

Quality and delivery

• Execute structured QA/QC using checklist-based reviews, cell protection, traceability notes, and exception flags in standardized Excel templates; maintain issue and action logs to track corrections and regulator comments, reflecting the SME’s discipline on data integrity and auditability.
• Maintain document control with consistent filenames, versioning, hyperlinks to source evidence, and regulator-ready PDF packages with bookmarks and indices, supporting efficient review cycles with clients, regulators, and subcontractors per SME practice.
• Coordinate with client technical contacts, NA regulators when requested by senior staff, and subcontractors for data validation or specialized analyses; schedule and document communications and follow-ups to maintain submission timelines

Collaboration and learning

• Participate in internal trainings on Title V, NSR/PSD, MACT/NESHAP, EPCRA Tier II/TRI, and state annual emissions statements; apply learning to improve calculations and templates, in line with SME guidance about the practice scale and expectations.
• Share lessons learned and template improvements with peers, contribute to frequently asked questions and SOP updates, and support onboarding for CL1/CL2 colleagues.

Qualifications

Education

• Bachelor’s degree in Chemical, Environmental, or Mechanical Engineering, Environmental Science, or Chemistry, with coursework or exposure in air regulations, mass balance, or environmental data analysis.

Experience

• CL2: 3–6 years handling NA permitting documentation and inventory/reporting tasks across multiple states; demonstrated experience in building regulator-ready workpapers and supporting client or internal audits in North America.
• Experience in the preparation of emissions inventories and a good understanding of handing stack emissions data 
• Experience setting up models in at least one of the following: Aermod, Calpuff or ADMS
• Experience of post-processing
• Demonstratable excel and report writing skills 

Skills

• Emissions estimation, factor selection, and activity data QA in Excel, with strong attention to traceability and unit conversions per NA program needs.
• Working knowledge of Title V, NSR/PSD basics, NSPS/NESHAP applicability concepts, AERR inputs, and state annual emission statements.​
• EPCRA Tier II/TRI fundamentals: chemical thresholding, mixtures, de minimis, SDS interpretation, and calculation documentation.
• Clear written communication for technical narratives and regulator-ready submissions, responsive coordination with clients, regulators, and subcontractors in a remote delivery model supporting.

Tools

• Advanced Excel with data validation, named ranges, protection, and change logs; exposure to Power BI dashboards for portfolio tracking preferred; familiarity with environmental compliance platforms like Cority or ACTS is beneficial.
