granted tier relief in April of 2020. The facility continues to have Zinc exceedances and the
most recent samples taken on May 14 had Nickel and Zinc benchmark exceedances. Since the

additional benchmark exceedances since then. The facility should still notify the division of any
benchmark exceedances.

Comment: All outfalls were observed during the inspection. Rip rap has been placed in areas where
erosion has occured. The SWPPP says that the facility was granted ROS for their outfalls. but I
do not see any evidence of this in Laserfiche. SWPPP says that outfall#2 represents outfalls
#1-6.
