Kingman Range MRS

Kingman Range MRS | Site History

1951: Arizona Army National Guard (ARNG) acquired a lease from a private owner to conduct weapons training. Training included small arms (.22-caliber, .30-caliber and .45-caliber) and submachine gun practice, as well as mortar and 3.5-inch rocket target practice. The firing line was located along Eastern Street, with firing from west to east into targets with a natural bedrock escarpment backstop located 1,500 feet away.

1968: The range is no longer operational and residential development of the former firing range began.

2008: The site is identified as a Non-Department of Defense, Non-Operational Defense Site (NDNODS) and Munitions Response Site (MRS).

2011- 2012: Site Inspection (SI) field work completed and the SI report was approved by ADEQ.

2017: The Remedial Investigation (RI) Quality Assurance Project Plan (QAPP) is approved and field work begins.

2019 – 2020: Draft RI reviewed by ADEQ and ARNG provides a notice for supplemental RI field work. A new draft RI is submitted with the draft feasibility study (FS) for ADEQ review.

2021: ADEQ hosted a virtual public meeting to inform the public about the site progress and gather new information from current residents and landowners. The RI/FS report was finalized and a draft Proposed Plan (PP) was submitted for ADEQ review. ARNG is finalizing the PP and anticipate the public comment period to begin summer 2021.
