Structurally, what seismic zones may the system be installed in?

Every microBLOX MBR system is designed to meet the following seismic criteria:
b. Seismic Importance Factor: 1.5
c. Occupancy Category: II
d. Mapped Spectral Response Accelerations: SS = 125.8%, Sd = 44.4%
e. Site Class: D
f. Spectral Response Coefficients: Sds = 83.9%, Sd1 = 46.1%
h. Component Anchorage Factors (Process Equipment): ap = 1.0, Rp = 2.5
