  • 2005 – MoDNR, Missouri Department
  • f Health & Senior Services, and

Federal Agency for Toxic Substances and Disease Registry (ATSDR) examined residents’ exposure to possible petroleum contamination in residential soils in Golden Hills Subdivision and Vich/Woodlawn Spring

  • 2006 – ATSDR concluded that the areas

presented “no apparent public health

hazard”

What Is Creosote?

Greenfield Environmental Multistate Trust LLC Trustee of the Multistate Environmental Response Trust

  • Thick, oily liquid used to preserve wood
  • Primary contaminant of concern at Site
  • Major chemicals in creosote: polycyclic

aromatic hydrocarbons (PAHs), phenol, and creosols

slide-21
SLIDE 21
  • 2006–2011: Under MoDNR oversight, Tronox

continued to operate protective systems installed by Kerr-McGee

  • 2009: Tronox filed for bankruptcy
  • 2011–2015: With limited funds ($2M) and no

guarantee of future funds, Multistate Trust assumed status quo operation of existing systems:

  • Groundwater/creosote recovery and treatment
  • Maintenance of closed impoundments
  • Groundwater monitoring and reporting

slide-22
SLIDE 22
  • Additional data required to evaluate corrective

measure effectiveness of monitoring network

  • Current recovery system may need optimization to

fully control plume migration and remove creosote

  • Potential exposure risks for soil, groundwater and

surface water exposure are limited

  • Additional evaluations may be required for potential

vapor exposer risks, if any additional groundwater contamination is found

Multistate Trust Findings To Date

slide-23
SLIDE 23

How Do We Identify Potential Exposure Risk?

  • 1. Is contamination present at concentrations

above levels established to be protective of human health?

  • 2. Is contamination moving in the environment?
  • By wind or in the air
  • With surface water or groundwater
  • 3. Can people be exposed to the contamination?
  • Direct contact (touching with skin)
  • Ingestion (eating/drinking)
  • Inhalation (breathing)

slide-24
SLIDE 24

Greenfield Environmental Multistate Trust LLC Trustee of the Multistate Environmental Response Trust

Existing Data Has Not Identified Potential for Contact/Ingestion for Soil or GW

  • Off-Site Soils: Previous limited off-site soil tests

showed no impacts to off-site soils

  • On-Site Soils: Site fencing and closure prevents

human contact with on-site soils

  • On and Off-Site Groundwater typically 1 to 4 feet

below ground surface

  • Unlikely to be touched
  • No record of public or private drinking wells or
  • ther wells in area
slide-25
SLIDE 25

Greenfield Environmental Multistate Trust LLC Trustee of the Multistate Environmental Response Trust

Evaluation of Potential Inhalation Exposure Risks

  • Sampled subsurface utility

corridors recently and found no pathway for workers

  • Will be collecting additional

information on vapors/odors if additional groundwater contamination is found

  • Will report on findings after

sampling and analyses are complete

slide-26
SLIDE 26

Multistate Trust’s New Site Work

  • 2015–2016: With receipt of additional remedy

funds:

  • - Multistate Trust completed initial field

evaluation

  • - Multistate Trust prepared Supplemental

Investigation Plan (includes vapor and

  • ther new studies) for MoDNR review/approval
  • 2016: Multistate Trust’s initial evaluation resulted

in replacement of Pumping Center 1 Trunk Line

slide-27
SLIDE 27

Objectives of Multistate Trust’s 2016 Supplemental Investigation

  • Provide comprehensive, up-to-

date, independent understanding of Site conditions

  • Delineate location and potential

migration and impacts of groundwater plume

  • Obtain technical data to
  • Evaluate current exposure

potential

  • Inform additional remedial

action, if required

Next Steps: Planned Activities in 2016 and Beyond

Greenfield Environmental Multistate Trust LLC Trustee of the Multistate Environmental Response Trust

  • Additional soil and groundwater sampling to

update and confirm current understanding of Site conditions

Next Steps: Planned Activities in 2016 and Beyond

Greenfield Environmental Multistate Trust LLC Trustee of the Multistate Environmental Response Trust

  • Specifically, Multistate Trust will address

uncertainties associated with current understanding of Site (monitoring wells installed 15-30 years ago)

  • Multistate Trust will determine whether existing

systems are adequate or should be modified to ensure overall protectiveness of remedy.
