R. O. Marsten, Process Survey / Environmental Impact Analysis Forms for the King City Mine (December 1972)

Set of handwritten Process Survey - Environmental Impact Analysis forms for the King City mine, dated 12/72 and completed by R. O. Marsten. The forms list storage tanks, noise sources, air emission streams (asbestos fugitive dust, ore screening dust, haul-road dust, diesel and gasoline exhaust) and solid residues (trash, overburden). Entries on the air emission pages give water sprays as dust control and respirators worn on windy days. A handwritten note says all samples show fewer than 5 particles/ml of 5 microns or greater.
