Benchmark Development Approach
1) Expanded from ambient air monitoring program need to address long-term as well as acute/subchronic exposures
- Tiered Approach
Tier I - action level Tier II - review Tier III - clearance
- Used existing regulations/guidance where applicable
Examples:
NAAQS for Pb (1.5 ug/m^) - action level for indoor air
HUD Pb Standard for floors (40 ug/ft^) - action level for interior dust
Otherwise developed risk-based screening levels
