Emerging Contaminants - The New Frontier - Paul Yaroschak Deputy Director for Emerging Contaminants Office of the Secretary of Defense
What is an Emerging Contaminant? • Chemicals & materials with: • Perceived or real threat to human health or environment • Either no peer reviewed human health standard or an evolving standard • May have: • Insufficient human health data/science • New detection limits • New exposure pathways
U.S & International Interest • U.S. National Geographic Magazine - Oct 06 • U.S. ES&T Magazine - Dec 06 • USGS Survey of 139 streams in 30 states • ECs found in 80% of streams • U.S. Executive Order 13423 (January 24, 2007) • DoD Chemical Management Plan • European Union – REACH • Registration, Evaluation, Authorization & Restriction of Chemicals
Our VisionImagine if the largest industrial complex in the nation could… • Predict which chemicals we use, or might use, have evolving science that may change the regulatory status and pose health or environmental risks. • Develop a consensus evaluation of types & magnitudes of the risks in using/releasing such chemicals. • Develop risk management options and invest in high-payback actions. • Achieve and measure risk reduction.
EC “Scan-Watch-Action” Process Over -the- horizon Review literature, periodicals, regulatory communications, etc. Monitor events; Conduct Phase I qualitative impact assessment Conduct Phase II quantitative impact assessment with risk management options RM Options to Governance Council

Likelihood of Toxicity Value/ Regulatory Change • Probability that Greenhouse Gas emission initiatives will restrict use/availability of SF6 • Probability the OSHA will revise the permissible exposure limit (PEL) for SF6 2-3 yrs 5-10 yrs
- Turning Options to Actions -Risk Management Examples • $114M in Perchlorate RDT&E • Drinking water treatment…southern California • Cleanup technologies • Sources & analytical procedures…isotopic analysis • Material substitution…simulators, flares, rocket fuel • $2M in RDX toxicity studies • Cancer studies completed & reviewed by EPA • Non-cancer studies to be completed end of 2007 • Small Business Innovative Research solicitation for naphthalene dosimeter • Two proposals accepted
EC Action List • Perchlorate • Royal Demolition eXplosive (RDX) • Cyclotrimethylenetrinitramine • Trichloroethylene (TCE) • Hexavalent Chromium • Naphthalene • Perfluorooctanoic acid (PFOA) • Beryllium } Elevated from Watch List 9-06 } Elevated from Watch List 9-07 Notes: - Some risk management actions underway including research on toxicity, substitutes, & treatment.
Tungsten Tetrachloroethylene (PCE) Dioxin 1,4-dioxane Nanomaterials Perfluorooctyl sulfonate (PFOS) Di-nitrotoluenes (DNT) Lead (Added 3-07) Nickel (Added 3-07) Cerium (Added 7-07) Cobalt (Added 7-07) EC Watch List • Cadmium (Added 12-07) • Manganese (Added 12-07) • Sulfur Hexafluoride (SF6) (Added 12-07) • Phase I Impact assessments completed
Accomplished • Established & refined the scan-watch-action process for ECs • EC News • Established a FY-08-13 DoD funding line for ECs • Completed 20 Phase I Impact Assessments • Established EC web sites for DoD & public • Perchlorate sampling data • EC info portal • Designated “material champions” for ECs on the action list • Completed two briefings to EC Governance Council – all recommendations approved
DoD Tungsten Work Group • Coordinating DoD efforts on: • Embedded fragments studies of tungsten-metal alloys (penetrator munitions)…W-Ni-Co is highly carcinogenic • Sodium tungstate toxicity studies (tungsten bullets)…rodent dosing studies underway • Tungstate fate & transport studies (tungsten bullets)…tungsten is both soluble and mobile • Operational Risk Assessment of tungsten use…risks associated with continued use…sponsored by Joint Ordnance Commanders Group • Completed tungsten fact sheet for public • Completed Q&A bank & key messages for public affairs use
Nanomaterials Work Group • WG formed with EC and DDR&E co-chairs • Charged with • Coordinating ESOH technical, policy, and legal information on engineered nanomaterials • Developing well-reasoned, evidence-based, consistent and coordinated DoD positions, messages, and actions on these issues. • Supports DoD nexus with the OSTP/CEQ/OMB Nanomaterials Policy Coordination Group • Developed Fact Sheet on Nanomaterials as an EC • Drafted interim guidance on responsibilities to evaluate and manage potential risks from nanomaterials • Awaiting NPCG agreement on definition of nanomaterials • Drafting DoD Nanomaterials Q&A package • To ensure consistent messages • To assist PAO’s response to inquiries
Projects of Interest to NMCPHC • EC Risk to Ranges analysis • Database Query procedures for DoD EC Use • Benchmarking Government & Industry Chemical Rating Systems - Phase I • Phase I Impact Assessments for W/Ni/Co alloys, SF6, lead, cadmium • Phase II Impact Assessments & risk management options for RDX, TCE, Be, PFOA, naphthalene, & hexavalent chromium • Toxicity & Human Health Criteria for Chemicals in Development/Acquisition
Summary • EC management requires new thinking • Proactive vice reactive…a paradigm shift • Make targeted investments before regulatory action • Base decisions on life cycle costs • Efficient process established for identifying & assessing ECs & developing risk management options • Leverages existing DoD assets/resources • Potential large payback • Protects people, mission and assets
Or get overtaken by it………….. Stay Ahead of ECs with “Scan-Watch-Action”
ECOS-DoD-EPA Work Group Products • Issue: How do states define ECs? What are ECs of concern? - Product: State EC Survey • How can states & federal agencies send a consistent risk message to the public? - Product: Risk communication paper • What values should be used if no IRIS value? - Product: Provisional toxicity values paper • What conditions, requirements, authorities influence the decision to expend funds on EC response when threat to human health is not clear? - Product: Action triggers paper Done Done Done Underway
REACH Implications for the Defense Industry • Regulated materials may become more difficult to obtain and more costly • Likely unexpected supply chain disruptions • DoD suppliers may not fully realize what chemicals are in their parts/articles from sub-suppliers; cross-contamination issues • Small suppliers may not be able to comply cost-competitively • May need to increase research/substitutes analysis during systems development • REACH calls for “the progressive substitution of the most dangerous chemicals when suitable alternatives have been identified” • Unknown effects on interoperability (e.g., NATO) and re-supply of U.S. forces in Europe • Unknown implications for foreign military sales
