Thomason Chemical Co., Inc., Craigmont ID

EXECITIVE SUMMARY

Thomason Chemical is located at the corner of Front Ave. and Third St. Craigmont, ID. The property was acquired in 1968 and additions were made to the building in 1974 and during the 1980’s. The site consists of one main building with additions and a smaller shed directly adjacent to the main building. The main building was previously used for commercial use in manufacturing metal products. Currently the building is filled with tools and materials used in the prior business and the smaller shed is empty. The shop was closed in 1990 and building abandoned in 2008. Mr. L. Thomason met with Environmental Restoration and Waste Management (ERWM) and Water Resources, Nez Perce Tribe April 2013 to discuss how the property evolved and the industrial applications. Mr. Thomason’s concerns involving chemical and hydrocarbon contamination and unidentifiable surplus from the Hanford Nuclear site.

Water Resources conducted a site visit and identified areas of concern. A report was generated and forwarded to Mr. Lincoln suggesting a Phase II Environmental Site Assessment (ESA) was needed to address areas of environmental concerns. Keltic Engineering was retained by the site owner and performed the Phase II ESA and environmental sampling in June 2013. Keltic Engineering recommendations in their report dated July 2013 that base upon lab results there are no significant environmental impacts at this site.

SITE HISTORY

April 12, 2013 ERWM was contacted by Mr. L. Thomason and made aware of a potential radioactive object land he is a representative for at 3rd and Front in Craigmont.

April 15, 2013 ERWM and Water Resource meeting with Mr. L. Thomason regarding unidentifiable surplus from the Hanford Nuclear site as possible nuclear material

April 15, 2013 ERWM requested assistance for the Dept. of Energy for assistance with classification of object.

April 19, 2013 Region Response Team 2 and Department of Energy, Region VIII response teams were contacted for an immediate response.

April 22, 2013 Officials with the Idaho Bureau of Homeland Security said a regional response team deemed the level of radioactivity very low, and the material didn’t pose any immediate threat to life or safety. The material was removed and returned to Hanford. No background radiation was detected at the site and the response action was ended.

May 1, 2013 Water Resources conducted a site inspection and 6 site concerns were listed.

  • Former residential well water sampling
  • Resolution of the cyanide and nitric acid spills
  • Identifying, removal and disposal of the remaining chemicals
  • Disposal the waste oil(s)
  • Test for the residual of TCE
  • Soil samples around the site
