Problems/Comments

The Former Joseph Guy Community Center was located in Kwethluk, Alaska. The site is a rural Alaskan village located approximately 12 miles East of Bethel. An Environmental Protection Agency (EPA) Targeted Brownfield Assessment (TBA) was completed in 2009/2010. The focus of the TBA was the former 5,000-square-foot Joseph Guy Community Center, which was incinerated during a fire in April 2006. A site visit was conducted on October 15, 2009 and the field work occurred on June 9, 2010. A total of 28 soil samples were collected and submitted to a laboratory for analyses. Surface soil samples inside the burned community center contained several metals that exceeded regulatory levels. Those metals included antimony, arsenic, chromium, cobalt, copper, and nickel. Two surface soil samples collected outside the burned community center contained concentrations of n-nitroso-di-n-propylamine and bis(2-ethylhexyl)phthalate above regulatory criteria. Deeper subsurface soil samples did not indicate any contamination, therefore indicating that the compounds had not migrated vertically. One surface soil sample collected near the distribution line of the former aboveground storage tank (AST) exceeded regulatory criteria for diesel range organics (DRO).

7/14/2011 Update or Other Action Communication with DEC RA and then Dave Bartos with EPA led to the conclusion that this is a relatively straight forward issue from a federal hazardous waste perspective. He did not see any reasonable basis to presume that the building debris would designate as a listed hazardous waste. If the entire remains of the burned-out building are disposed of as a single waste stream, it would be unlikely for the demolition debris to exhibit a hazardous characteristic. Formally, whomever is doing the building demolition and disposal is responsible for making hazardous waste designation, but thinks this is reasonable guidance for making the determinations. There may be environmental issues that need to be addressed, but it sounds like they are contaminated sites issues, not RCRA hazardous waste management issues.

9/1/2013 Final Cleanup Report Reviewed Final ERM 'Brownfield Cleanup Action, Joseph Guy Community Center' report reviewed and approved. Report dated June 2013. All metals contaminated material were removed, passed TCLP and SPLP sampling and were deposited in supersacks at the Kwethluk dump. Residual arsenic concentrations are similar to background arsenic, both of which exceed direct contact cleanup levels. Residual isolated areas of arsenic, chromium and copper exceed MTGW cleanup levels and may be attributed to treated timbers used to construct the building that were burned. Samples of the metals-bearing soils did not fail leaching tests, and direct contact cleanup levels were deemed appropriate for site. John Carnahan

Requirements

Description Details
Advance approval required to transport soil or groundwater off-site. Installation of wells on the property with the intent of extracting groundwater for any purpose requires DEC approval.
Advance approval required to transport soil or groundwater off-site. Any proposal to transport soil off-site requires DEC approval in accordance with 18 AAC 78.600(h). A “site” [as defined by 18 AAC 75.990 (115)] means an area that is contaminated, including areas contaminated by the migration of hazardous substances from a source area, regardless of property ownership. Movement or use of contaminated material in a manner that results in a violation of 18 AAC 70 water quality standards is prohibited.
Periodic Review Any future change in land use may impact the exposure assumptions cited in this document. If land use and/or ownership changes, these management conditions may not be protective and DEC may require additional remediation and revised conditions. Therefore the Organized Village of Kwethluk shall report to DEC every five years to document land use, or report as soon as the Organized Village of Kwethluk becomes aware of any change in land ownership and/or use, if earlier. The report can be sent to the local DEC office or electronically to DEC.ICUnit@alaska.gov.
