John Lynch, P.E. Palisade Software Miami Users Conference October 25, 2007 Quantifying Financial Environmental Risk Using Probabilistic Cost Estimating www.johnwlynch.com
Environmental Probabilistic Cost • Drivers 15 minutes • Regulatory Reporting • Financial Planning • Liability Management • Techniques & Practices 15 minutes • Precision & Accuracy • Expert Panels • Resources • Case Studies 15 Minutes • California Munitions Plant • New Jersey River Sediments PRP • Manufactured Gas Plants 15 Site Portfolio • Discussion – Q&A 15 Minutes
Regulatory Reporting Drivers • Need to quantify environmental liability under uncertain conditions • “Not understanding the problem is not an excuse for not having an answer” • New accounting rule • FIN 47 … Financial Accounting Board Interpretation Notice • Asset Retirement Obligation
FIN 47 • Financial Disclosure of Environmental Liabilities • Old ….. Potential loss must be “probable” and can be “reasonably estimated” • New …. Use probabilistic tools • FASB Interpretation No.47 • Accounting for Conditional Retirement Obligations • The obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and (or) method of settlement.
Financial Planning • Estimates for accruing reserves • Tax and cash flow issues • Uncertainties • Need, scope, timing • Regulatory • Dissolution of entities • Trusts, corporations
Liability Management • Transfer Liability Obligation to Third Party • Need legal entity • Adequate funding • Reliable and credible estimate • Secure mechanism • Insurance • Trust • Reliable Remediation Contractor
Techniques & Practices • Uncertainties • Site …. How much, where, what • Soils, groundwater, sediment • Site characterization … risk vs. remedy • Poor use of site characterization data • Contaminants • Location, concentration, remedy impact • Regulatory status • Technologies … what to do? • Will it work • How much will it cost
Techniques & Practices (Con’t) • Regulatory • Federal (EPA), States (DEP, DEQ, etc.), Tribes, Fish & Wildlife, Third Parties • Superfund … Record of decision (RoD) • ARAR Applicable or Relevant and appropriate requirements? What are they? • Classification of Waste • RCRA, Listed wastes • Contaminated Media • Land ban on disposal
Precision vs. Accuracy • Cost Estimating Tools • Lots of detail • Require an engineering design • Not available for most projects • Unit cost • $/acre of cap • $/gallon of stripping
Technology Resources • Federal Remediation Technologies Roundtable • http://www.frtr.gov/ • Means Estimating Guide
Techniques • Lack of historical cost data • Inconsistency of remedy selection • Not much cost data • Insurers have loss/claims data • DoD, DoE have good technology cost data. • Regulatory uncertainty is most difficult • Evolving standards • Expert panels vs. data • Access to data and decision makers
Expert Panels • 3 to 5 senior technical & regulatory professionals • Mid-level support • Review documents • Identify alternatives • Low, medium, high • Use decision tress • Probabilities • Costs • Run model and “gut test” results
Case Study #1 • California Munitions Plant • Driver…. Insurer needed to establish reserve • WWII Era Munitions Plant • Large Site • Multiple Environmental Issues • Groundwater …. 3 public water supplies impacted • Perchlorate … environmental – public health standard not established • CA, EPA, DOD, USAF
Case Study 1 (Con’t) • Perchlorate Drinking Water Standard • CA and US EPA • Uncertainties • MCL – drinking water standard • 3 – 30 µg/l (ppb) • Extent of GW contamination • Plume footprint • Effectiveness and acceptability of treatment technology • RO, biological
Case Study #2 • River Sediment PRP • Trust holding liability • Estimate needed to dissolve trust and distribute assets to heirs • Credible estimate for regulatory and other RPs. • Billion dollar remedy • Uncertainties • Scope … sediment removal for navigation • Technologies … • Removed material management • Capping material • Dredging technology
Case Study #3 • SE Utility’s Manufactured Gas Plants (MGPs) • Utility has responsibility for environmental of 15 MGPs …. $75M to $150M. • Regulatory Agencies allowed recovery of environmental costs for a limited time • Utility wanted to use an finite risk environmental cost cap insurance policy to fund the cleanup • Needed an estimate of the cleanup costs • Uncertainties • Scope .. Soil, Groundwater, Sediments • Regulatory … Standards, Technology.
Additional Applications • DoD • BRAC. Cost Cap Insurance • EU Petroleum Company • US legacy holding • Las Vegas Developer • Former munitions plant. Cost Cap Policy • Texas refinery • Settle suit over cleanup liability
