ABSTRACT A net environmental benefits analysis (NEBA) approach offers a powerful set of tools for rigorously evaluating and comparing the natural resource benefits of alternative mitigation, restoration, enhancement, and preservation actions for compensating for natural resource damages, site remediation and pipeline-siting projects, for example. Combining the results of the NEBA with an assessment of the costs of the alternative measures shows which alternative(s) achieve a net environmental benefit at least cost. NEBA uses environmental or monetary metrics to measure the change in the value of ecological services from the site under alternative actions compared to the baseline condition. This presentation describes a NEBA application to a pipeline-siting project. The approach is equivalent to evaluating compensatory restoration as part of a natural resource damage assessment (NRDA) under the Oil Pollution Act of 1990 (OPA 90). For example, under NRDA, a habitat equivalency analysis (HEA) model almost always is used in a two-sided NEBA, which sums the negative environmental benefits—interim losses—that result from the oil spill injury on the debit side and compares to the sum of the positive environmental benefits due to the compensatory restoration actions on the credit side. Most reports prepared as part of NRDAs are confidential. However, the NEBA used in the present pipeline-siting example is equivalent to how it has been applied in NRDA applications including two oil spills involving pipelines, the Colonial Pipeline Sugarland Run NRDA and the Colonial/Texaco Pipeline San Jacinto River Oil Spill. The present pipeline-siting example uses NEBA to determine the quantity of quality-adjusted acres of forested wetland that are needed to offset a loss in forested wetland acreage because of the construction and operation of the proposed pipeline.

ABSTRACT Natural Resource Damage Assessment (NRDA) under the Oil Pollution Act of 1990 (OPA) is a process used to determine the amount of compensation due to the public for natural resource injuries arising from oil spills. Two models, Resource Equivalency Analysis (REA) and Habitat Equivalency Analysis (HEA), are used in essentially all OPA NRDAs to compute compensatory restoration requirements. REA is applied when members of wildlife populations are injured: usually mortality or a loss of reproduction among a species of bird, turtle, marine mammal, or fish. HEA is used when habitats are injured: usually oiling of beaches, wetlands, or sediments. The models are often implemented in a cooperative setting with input from both the Responsible Party and the Trustees. In this setting the models provide a structure for organizing negotiations and identifying the types of agreements that need to be reached before restoration can be identified and “right sized.” The models also have a technical basis in economic theory that is fully justified, but only in particular, limited circumstances. This technical basis is the only means of assuring the Trustees, RPs, and stakeholders that the NRDA process has identified an appropriate level of compensation. When the circumstances of a spill do not approximate those in which HEA and REA are defensible, creative solutions are needed to adjust the models to the circumstances of the case if they are to provide a convincing basis for scaling restoration and reaching resolution. This paper identifies the circumstances under which REA and HEA are fully defensible as well as 35 years of evolving adjustments designed to make them “work” when applied to real-world cases they do not quite fit. We also look to the future and how climate change may alter restoration scaling.

Natural Resource Damage Assessment

ABSTRACT The Damage Assessment Regulations Team (DART), under the Office of General Counsel of the National Oceanic and Atmospheric Administration (NOAA), has centered its efforts on developing natural resource damage assessment regulations for oil pollution in navigable waters. These procedures will likely lower the costs associated with damage assessments, encourage joint cooperative assessments and simplify most assessments. The DART team of NOAA is developing new regulations for the assessment of damages due to injuries related to oil spills under the Oil Pollution Act of 1990. These regulations will involve coordination, restoration, and economic valuation. Various methods are currently being developed to assess damages for injuries to natural resources. The proposed means include: compensation tables for spills under 50,000 gallons, Type A model, expedited damage assessment (EDA) procedures, and comprehensive procedures. They are being developed to provide trustees with a choice for assessing natural resource damages for each oil spill.

ABSTRACT For petroleum fingerprinting in support of natural resource damage assessments (NRDA) and other regulatory and litigation-driven scientific studies, the state of the art now focuses on polycyclic aromatic hydrocarbons (PAH) and saturated biomarker analyses, coupled with ratio and/or principal component analysis techniques, for advanced chemical fingerprinting (ACF) and allocation of petroleum mixtures to multiple sources. This strategy is being applied to oil spills, in-ground petroleum releases, and coal tar-petroleum source differentiation scenarios. The National Oceanic and Atmospheric Administration's (NOAA) draft injury guidance on NRDA recommends the application of ACF to oil spill assessments under the Oil Pollution Act of 1990.

Compensatory Restoration

ABSTRACT Some oil spills cause losses of ecological services in coastal wetlands, other shoreline environments, intertidal ecosystems, and upland environments. In the United States, habitat equivalency analysis (HEA) is being used frequently in natural resource damage assessments for such oil spills to determine the scale of compensatory-restoration projects needed to offset the ecological service losses. The cost of the scaled compensatory-restoration project(s) that offset the ecological service losses is the measure of natural resource damages for the lost ecological services. Our paper describes the HEA process and provides an example of its application. Then we examine several challenges that arise in some HEA applications, including the role of leasing versus purchasing compensatory habitat, increasing values of compensatory habitat over time due to decreasing availability, accounting for service gains from compensatory habitat in the distant future when the present value of those services is essentially zero, and addressing uncertainties in estimating HEA inputs (such as the magnitude of annual service losses and gains). The final section of our paper provides our conclusions with respect to these challenges.

The Cost

ABSTRACT The new Oil Pollution Act of 1990 defines natural resource damages from oil spills as the sum of the cost to restore foregone natural resource services, the diminution of value of natural resource services prior to restoration, and damage assessment costs. Natural resource damages are usually determined once removal activities (containment, protection, and cleanup) are completed. Nevertheless, removal activities affect the magnitude of all three natural resource damage components. Consequently, to minimize the total cost of oil spills, decisions on removal activities should consider the linkages between removal activities and natural resource damages. Successful containment results in minimal natural resource damages, because oil generally does far less damage to natural resources in open water than on shore. If oil cannot be contained, the potential natural resource damages from oil coming ashore in certain areas can help determine priorities for protection activities. In particular, oil may harm natural resource services much more in some areas than in others. Furthermore, some natural resource services are more costly to restore and assess than others. Finally, some cleanup activities do more harm than good to natural resource services. If the effects of cleanup activities on natural resource damages are ignored, “excessive” cleanup activities are likely.

The Relationship

ABSTRACT The natural resource damage assessment (NRDA) process under the Oil Pollution Act regulations is restoration-focused. In order to proceed with a NRDA after Preassessment Phase activities are completed, the natural resource trustees must determine that feasible restoration actions are available to address the potential injuries resulting from the discharge of oil. If this determination is made, the trustees can move forward and conduct injury assessment and injury quantification as part of the Restoration Planning Phase. The availability of appropriate restoration alternatives for natural resources can have a profound effect on the nature of both injury assessment and injury quantification that is necessary for a particular oil spill. This paper examines that relationship, using some examples from settled oil spill NRDA cases to illustrate how the availability of appropriate and cost-effective restoration alternatives can reduce the overall cost of a NRDA and the length of time necessary to reach an appropriate settlement. The type of restoration and the degree to which it is scaleable can also influence both cost and time to reach settlement. It also discusses some of the factors that are important in determining to what degree restoration opportunities influence the injury assessment and quantification process for oil spills, including geographic location, previous experience with similar spills, and the degree of cooperation that exists between the trustees and the responsible party.

AbstractMicrobiomes of freshwater basins intended for human use remain poorly studied, with very little known about the microbial response to in situ oil spills. Lake Pertusillo is an artificial freshwater reservoir in Basilicata, Italy, and serves as the primary source of drinking water for more than one and a half million people in the region. Notably, it is located in close proximity to one of the largest oil extraction plants in Europe. The lake suffered a major oil spill in 2017, where approximately 400 tons of crude oil spilled into the lake; importantly, the pollution event provided a rare opportunity to study how the lacustrine microbiome responds to petroleum hydrocarbon contamination. Water samples were collected from Lake Pertusillo 10 months prior to and 3 months after the accident. The presence of hydrocarbons was verified and the taxonomic and functional aspects of the lake microbiome were assessed. The analysis revealed specialized successional patterns of lake microbial communities that were potentially capable of degrading complex, recalcitrant hydrocarbons, including aromatic, chloroaromatic, nitroaromatic, and sulfur containing aromatic hydrocarbons. Our findings indicated that changes in the freshwater microbial community were associated with the oil pollution event, where microbial patterns identified in the lacustrine microbiome 3 months after the oil spill were representative of its hydrocarbonoclastic potential and may serve as effective proxies for lacustrine oil pollution.

We have analyzed the two- and three-ring aromatic hydrocarbons from the Wild Harbor oil spill in September 1969 and the Winsor Cove oil spill in October 1974, in intertidal marsh sediments, using glass capillary gas-chromatographic and mass-fragmentographic analyses. Naphthalenes with 0–3 alkyl substitutions and phenanthrenes with 0–2 substitutions decreased in concentration with time in surface sediments. The more substituted aromatics decreased relatively less and in some cases actually increased in absolute concentration. The changes in composition of the aromatic fraction have potential consequences for the ecosystem and provide insight into geochemical processes of oil weathering.

AbstractNatural resource trustee agencies must determine how much, and what type of environmental restoration will compensate for injuries to natural resources that result from releases of hazardous substances or oil spills. To fulfill this need, trustees, and other natural resource damage assessment (NRDA) practitioners have relied on a variety of approaches, including habitat equivalency analysis (HEA) and resource equivalency analysis (REA). The purpose of this paper is to introduce the Habitat-Based Resource Equivalency Method (HaBREM), which integrates REA’s reproducible injury metrics and population modeling with HEA’s comprehensive habitat approach to restoration. HaBREM is intended to evaluate injury and restoration using organisms that use the habitat to represent ecological habitat functions. This paper seeks to expand and refine the use of organism-based metrics (biomass-based REA), providing an opportunity to integrate sublethal injuries to multiple species, as well as the potential to include error rates for injury and restoration parameters. Applied by NRDA practitioners in the appropriate context, this methodology can establish the relationship between benefits of compensatory restoration projects and injuries to plant or animal species within an affected habitat. HaBREM may be most effective where there are appropriate data supporting the linkage between habitat and species gains (particularly regionally specific habitat information), as well as species-specific monitoring data and predictions on the growth, density, productivity (i.e., rate of generation of biomass or individuals), and age distributions of indicator species.
