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.
