EPA 18cv3472 NDCA Tier 1 Agency and industry collaboration Refineries are highly variable and complex Site sampling and data collection Generic Sampling Plan Removal of PAHs and naphthenic acids Quality Assurance Project Plan (QAPP) Key takeaways and conclusion 2 ED_002061_00096619-00002 Collaboration through the years 1st refinery ELG meeting with EPA was May 26, 2016 Working together, we have: - Improved 308 survey clarity and quality - Strengthened agency's understanding of refining operations through presentations and site visits Need to resolve remaining issues with generic sampling plan and quality assurance project plan (QAPP) Sierra Club v. EPA 18cv3472 NDCA Tier 1 WHY do they vary? Age and evolution: retrofitting, process improvements Crude availability, slate Local and/or state fuel standards Market size and competition Product mix Regulations Transportation options HOW do they vary?
