Overview of US Programs to Address Contaminated
Sites

• RCRA a program for existing sites
• Lists facilities but does not rank them
• Set goals to prioritize resources
• Industry funded cleanups
• Federal oversight of State-led cleanups.
• Superfund a program for abandoned sites
• Ranks sites to qualify access to funding
• Government funded cleanup, but with provision for
  cost-recovery
• Federal Facilities Agreement tool.

Overview of RCRA Program

• RCRA is a program to manage solid and hazardous
  waste.
• Key hazardous waste components of the program
• Defines a hazardous waste
• Issues operating permits
• Hazardous waste generators
• Treatment, storage, or disposal facilities
• Tracks the generation of hazardous waste
  (manifests)
• RCRA has a four-phase Corrective Action (CA)
  Program
• RCRA Facility Assessment
• RCRA Facility Investigation
• Corrective Measures Study (CMS), and
• Corrective Measures Implementation (CMI)

Corrective Action Program

• When is corrective action (CA) required?
• When applying for a permit,
• Upon discovering a release, or
• Upon discovering other SWMU or releases.
• How many facilities are subject to cleanup under
  RCRA?
• Currently about 6,900 facilities
• About 3,746 have CA underway or will need to.
• Facility owner/operators (including federal,
  state, and local Gov) are responsible for
  implementing corrective actions

Prioritizing Resources RCRA

• No ranking To prioritize resources, EPA
  established specific short-term goals for the
  1,968 highest-priority facilities on the current
  RCRA Cleanup Baseline.
• Other steps Create solid waste management units
  (SWMUs) to facilitate management

Overview of Superfund Program

• Why Superfund?
• Provides for national emergency response
• Provides government witht the resources to
  remediate abandoned sites or those that have a
  recalcitrant PRP
• Makes responsible parties pay via a financial
  recovery mechansim
• Established a strong incentive to prevent
  chemical releases because of liability clause
• A site must be listed in order to qualify for
  use of Superfund funding
• Superfund sets priorities for use of the fund
  based on ranking using criteria in the hazard
  ranking system.

8
Prioritizing Resources Superfund

• The HRS score for a site is determined by
  evaluating four pathways of potential human
  exposure
• Ground water migration (drinking water)
• Surface water migration (drinking water, human
  food chain, and environmental)
• Soil exposure (resident population and nearby
  population) and
• Air migration (population, sensitive
  environments).
• Any site scoring 28.5 or above is eligible for
  the National Priorities LIst.

9
Recommendations for Setting Priorities

• Prioritize remedial programs based on
• Sites with a known responsible party
  (owner/operator)
• Abandoned sites
• Create other sub-lists as necessary to create a
  manageable work-load (ranking not always
  necessary to set priorities).
• Prioritize based on a known release and a pathway
  that poses the greatest threat of exposure.
• Facilitate management based on chemicals
  associated with industry-sectors.
• Promote early risk reduction and site
  stabilization at all contaminated sites.
• Facilitate public involvement it will take
  longer, but will be provide long-term benefits
