northport removal action
Northport Removal Action
  • In 2004, EPA initiated a removal at the Le Roi smelter
  • 29 properties had soil removed
  • 94 properties had exposure reduction measures
  • 65 properties had no action
two different soil sampling plans
Two Different Soil Sampling Plans
  • Upland soils
    • Teck is lead, EPA approves sampling plan
    • Human health and ecological
    • Broader scope
  • Residential
    • EPA is lead
    • Specific to properties in sampling area that have residences
    • Human heath focused
goal of upland soils study
Goal of Upland Soils Study
  • Determine where there may be harmful levels of metals in soil from smelter impacts and define the outer limit of concentrations which could cause problems to people or the environment.
  • Collect data to evaluate human health and ecological risks associated with contaminants in uplands soil
schedule for upland soils
Schedule for Upland Soils
  • Teck to submitted Draft Sampling Plan to EPA in September 2013
  • EPA (and Participating Parties) are currently reviewing Sampling Plan and will submit comments in December
  • Goal is to finalize Sampling Plan by spring 2014 and start sampling summer 2014. Sampling may extend into 2015.
residential soil sampling
Residential Soil Sampling
  • Ecology report gave enough data for EPA to prioritize a Residential Soil Sampling program
  • EPA is drafting the sampling plan
residential soil sampling schedule
Residential Soil Sampling Schedule
  • Fall 2013- contact land owners, develop general sampling plan
    • Informal notice letting landowners know they are in the area of interest for sampling (to be sent in next couple weeks)
    • Formal Access Agreement will be sent requesting permission to sample property (December)
  • Winter to Spring 2014- finalize general sampling plan
