EPA Building Survey
Between January 2000 and September 2001, EPA and its contractor, Tetra-Tech, reviewed Boeing's and DOE's final status and verification surveys of 11 prior radiological facilities that had undergone D&D survey and release. EPA and Tetra-Tech also conducted radiological surveys of 8 of these facilities.
On January 9, 2003, EPA issued the final reports of its three year assessment of Boeing's remediation and survey process for releasing radiological buildings for unrestricted use.

- Building 4009, 4011, 4019, 4055, and 4100 document review
- Building 4012, 4023, 4028, 4029, and 4363 document review
- Building 4059 document review
EPA reached the following conclusions:
- "Previous DOE/Boeing surveys sampled in appropriate and representative locations"
- "Measurements made in previous surveys were accurate"
- "EPA concurs with the conclusions made by the Department of Energy (DOE) and Boeing Rocketdyne about the locations and levels of residual radioactivity"
- "Residual radioactivity does not exceed DOE and Nuclear Regulatory (NRC) established limits for unrestricted use."
EPA therefore confirmed that prior surveys had been conducted in a correct, appropriate and compliant manner.
