Document, Report, or Work plan Review - other |
Interim report submitted by Shannon & Wilson (S&W) with this date describing the fall 2011 soil treatment activities for the stockpile generated during contaminated soil removal from beneath the Huslia Elementary School. The contaminated soil was initially stored in containers near the school - S&W estimates there was less than 2 cubic yards. S&W submitted a workplan in August 2011 proposing landfarming, which was approved on 8/9/11 by DEC PPR staff. In August and September, S&W constructed a lined 24x40 feet landfarm with 1-foot berms at the old landfill site in Huslia. The contaminated soil was spread 3 inches thick, sampled, and fertilized. The soil was covered in October for the winter. The report indicates S&W plans to hire a local resident to uncover the soil in the spring and will return next fall to sample and fertilize if necessary. |

Shannon & Wilson submitted stockpile sampling report dated 8/1/13 for the landfarm at the old landfill site. Samples were collected from the contaminated soil and from beneath the liner. DRO remained in the contaminated soil up to 17,700 mg/kg. Due to the remaining DRO contamination, the contaminated soil was placed in super sacks and sent to OIT in Fairbanks for thermal remediation. No contaminants were found above DEC cleanup levels from the two samples collected beneath the liner. |

A Site Characterization Report, dated 6/27/14, was submitted by Nortech. Site characterization confirmed that 2-3 cubic yards of contaminated soil remained beneath the building next to the foundation where it could not be removed. The residual contamination included BTEX and DRO above soil cleanup levels.
To reduce the potential for vapors from the residual soil contamination, a soil vapor extraction system was installed in the excavation in March 2011. A vapor barrier was installed over the crawlspace soil. A fan was also installed to ventilate the crawlspace. In April Nortech worked with YKSD staff to ventilate the boiler room where the spill occurred to exhaust vapors from this room to the outside rather than push them into the school. Air samples collected in March and April indicated that benzene and naphthalene slightly exceeded the residential indoor air target level in the school; however, only benzene exceeded in the crawlspace. Vapors are expected to continue to reduce as the building is further ventilated. |

Document, Report, or Work plan Review - other |
ADEC staff reviewed the "2018 Summary Report, Huslia Soil Assessment" submitted by Shannon & Wilson, December 3, 2018. Some contaminated soils were identified and excavated in 2017 during a construction project next to the elementary school. In 2018, the elementary school building was relocated to a location west of the existing high school, and 260 cubic yards of contaminated soil was removed and taken to a landfarm on property owned by the City of Huslia. during this work an abandoned underground tank was also found and removed. ADEC responded in a letter with comments about additional borings to characterize the horizontal and vertical extent of contamination left on school grounds. |

Meeting or Teleconference Held |
ADEC staff met with the Yukon Koyukuk School District Capitol Projects Manager to discuss funding sources, last year's construction activities, and current understanding of risk to contaminated sites. Both the state and the school district plan to pursue additional funding, and work with consultant to develop a work plan for site characterization. |

Update or Other Action |
Updated exposure tracking model and problem statement to reflect data from Shannon & Wilson's 2018 site characterization report. Appears that UST was an additional source given depth of contaminated soil. UST was abandoned in place as part of 2010 removal action by OASIS due to the presence of utility lines. |

Meeting or Teleconference Held |
Met with new IGAP coordinator for Village of Huslia to discuss status of contaminated sites and introduce the Contaminated Sites Program's role. Went over cost recovery, the need for additional site characterization, restrictions on excavation within contaminated sites, and possible sources of funding. Informed her that we would be sending a request for additional site investigation to the City documenting what remains to be done at each site and providing a paper trail of our conversation. The village has been dealing with significant erosion and issues backhauling lead acid batteries, which has been driving most of their grant funding requests. |
