Risk Characterization
Target risk range - Carcinogenic
- EPA Guidance (OSWER Directive 9355.0-30)
- Where cumulative carcinogenic site risk to an individual based on reasonable maximum exposure for both current and future land use is less than 10-4 , action is generally not warranted.
- Action may be taken at less than 10-4 based on site-specific concerns, but all records of decisions for remedial actions taken at sites posing risks within 10-4 to 10-6 must explain why remedial action is warranted.
- TNRCC Guidance target risk = 10-5
- BP RBDP Guidance target risk = 10-6 for residential land use, 10-5 for commercial land use and 10-4 for industrial land use.
