• Site-specific performance and risk assessments (also called safety assessments) are used to inform and support management decisions and to demonstrate compliance with the performance objectives under CERCLA, RCRA, and NEPA, 10 CFR 61, DOE Order 435.1, and NDAA Section 3116:

� waste form development and implementation;

� tank closure activities;

� waste site closure activities;

� in-situ decontamination and decommissioning;

� soil and groundwater remediation; and

� management of disposal facilities

• To protect human health and the environment

Performance and Risk Assessments

inform and support management decisions associated

with regulatory compliance with CERCLA, RCRA, NEPA,

10 CFR 61, DOE Order 435.1 and NDAA Section 3116.

P&RA CoP History

• DOE EM sponsored the Performance Assessment Community of Practice (PA CoP) in 2009, to:

a) provide means to address consistency early and throughout PA process;

b) foster early and sustained communication among CERCLA, NEPA, RCRA, and DOE O 435.1 activities involving LLW, tank closure, and D&D;

c) provide a forum to share information regarding state of the art and specific models, data and approaches; and

d) serve as an enduring data and modeling resource to minimize duplication of

effort across DOE and train future generation of PA professionals

• In late 2013, the group was broadened as P&RA CoP to emphasize:

a) the need for an integrated regulatory framework when cleanup work at a given site is subject to overlapping environmental regulations (CERCLA, RCRA, NEPA, and DOE Order 435.1); and

b) the importance of risk assessments in non-DOE self-regulated cleanup activities
