Lead Mitigation and Interior Cleaning, Ketchikan and Kotzebue, Alaska

Brice Engineering Services (BENG) performed lead mitigation and clean-up at two armories with Indoor Firing Ranges (IFR) in Ketchikan and Kotzebue, Alaska. Ketchikan is the most southeastern city in Alaska. The AKARNG maintains an armory in Ketchikan and the armory’s lower level was utilized as an IFR. The space was converted to general administrative space in 1990; additionally, the armory underwent a renovation. Many lockers and office furnishings had been exposed to dust from the renovations completed in 2015 and 2016. During the construction, lead dust was circulated through the armory. Lead has been detected in both the Ketchikan and Kotzebue armory buildings at concentrations above the 40 μg/ft2 threshold. Brice removed lead surface contamination to eliminate environmental health hazards and bring the former IFRs in the armories into compliance with the National Guard Pam 420-15 guidelines, and to allow for the IFR conversion process to continue. This was accomplished through the implementation of lead mitigation actions and housekeeping.
