On October 7, 2021 the final loads of asbestos containing waste material were shipped from the NFPI site for disposal and USEPA, its contractors, and all of the equipment that was used left the site by the end of the week. This completes the USEPA's clean up at the site.

In summary, the USEPA removed asbestos containing materials from the former kiln building, from piles of building debris, and from the soil surface of the 103 acre NFPI site. The USEPA removed over 4000 cubic yards of asbestos wastes and properly sealed them before transport from NFPI to a permitted off-site disposal facility in Joseph City, Arizona.  In addition, the 10-bay kiln building was also demolished as part of the cleanup.

During clean up work hours USEPA placed air monitoring units inside and outside the work areas to ensure that asbestos did not spread. If a monitor had detected dust (as an indicator of possible asbestos) above a specified safe level, then work would have been stopped and dust control measures re-evaluated. However, at no time during the clean up was dust detected above that safe level.

In the future, the Navajo Nation EPA will continue assessment and cleanup activities at the site to address remaining asbestos and other types of contamination within soils and groundwater at the site.
