Waste Water and Sanitation · Merged into 566X1, effective May 1, 1975
One changing predecessor in the explicit two-shredout collapse into the report's stated present designation; printed shredout code preserved. Verified source wording: “Environmental Support Specialty (AFSC 566X1). In July 1971, the specialty was renamed Engineering Environmental Support and two shredouts were created: Water Supply and Treatment (563X0A) and Waste Water and Sanitation (563X0B). In May 1975, the shredouts were dropped and the specialty assumed its present title and designation.”
