OUR REVIEWAir Toxics Review◦ Review calculations and compare

Hazardous Air Pollutant (HAP) levels to heath-based values.

Ambient Modeling◦ Health-Based Values

PSD Increment Modeling◦ Meet the stringent Class I standards

within the park.

OUR REVIEWPublic Comment Period◦December 8, 2017 to January 26,

2018◦ 30-days required, extended

◦ Public Hearing ◦ January 17, 2018

Concurrent EPA review during Public Comment

OUR REVIEWConsulted with Federal Land Managers

◦ Monthly meetings with EPA, NPS, and FWS.

Best Available Control Technology (BACT)◦ Required for PSD projects.

◦ Takes $ into account, control is chosen on a cost per ton reduction ($/tpy reduced).

BACT-Like Control Technologies◦ The focus on emission reductions, not costs.

◦ As good or better controls than those required under BACT.
