State Washington Regulations Chapter 173-183 WAC Preassessment screening and oil spill compensation schedule regulations Last Update: 5/12/03 -------------------------------------------------------------------------------- 173-183-010 Purpose. The purpose of this rule is to establish procedures for convening a resource damage assessment (RDA) committee, preassessment screening of resource damages resulting from oil spills to determine which damage assessment methods to use, and determining damages in cases where the compensation schedule is selected as the damage assessment methodology to apply. The RDA committee, utilizing the preassessment screening process, shall determine whether a detailed resource damage assessment studies should be conducted or whether the compensation schedule authorized under RCW 90.48.366 and 90.48.367 will be used to assess damages for each oil spill into state waters.

(1) If the RDA committee, after considering the factors enumerated in WAC 173-183-240(3), determines that the damages to be investigated are quantifiable at a reasonable cost and that proposed assessment studies are clearly linked to quantification of the damages incurred, then the RDA committee may authorize damage assessment studies. (2) If the RDA committee authorizes damage assessment studies under RCW 90.48.367(3), the RDA committee chair shall promptly notify the potentially liable party of this decision. (3) The state trustee agency(ies) responsible for the potentially injured resource and habitat shall conduct the damage assessment studies and pursue all appropriate remedies with the responsible party. The RDA committee shall consider the proposed damage assessment studies and the effects of any proposed remedies in a timely manner, consistent with WAC 173-183-240(3). (4) As new information becomes available, the committee may reevaluate the scope of damage assessment studies using the factors listed in WAC 173-183-240(3), and may reduce or expand the scope of damage assessment studies as appropriate. (5) The department may negotiate with a potentially liable party to perform restoration and enhancement projects or studies which may substitute for all or part of the damages determined through the damage assessment studies. [Statutory Authority: Chapter 90.48 RCW. 92-10-005 (Order 91-13), § 173-183-250, filed 4/23/92, effective 5/24/92.] -------------------------------------------------------------------------------- 173-183-260 Restoration and enhancement projects proposed by the PLP. (1) The potentially liable party (PLP) may propose restoration or enhancement projects or studies during the preassessment screening phase to substitute for some or all of: (a) The damages calculated from the compensation schedule authorized under RCW 90.48.366 and 90.48.367; or (b) The claims from damage assessment studies authorized under RCW 90.48.142 and 90.48.367. (2) To be considered as part of the preassessment screening decision process specified in WAC 173-183-240, PLP proposals must be submitted to the RDA committee chair within ten days of PLP notification by the RDA committee. (3) The RDA committee may accept the PLP proposal in lieu of some or all of: (a) The damages calculated from the compensation schedule authorized under RCW 90.48.366 and 90.48.367; or (b) The claims from damage assessment studies authorized under RCW 90.48.142 and 90.48.367. (4) For the RDA committee to find a proposal sufficient to adequately compensate the people of the state for public resource damages, the PLP proposal must at least contain the following elements: (a) An investigation of all potentially injured public resources to determine if they have been exposed to the spilled oil; (b) Follow-up investigations on all public resources documented to be exposed to determine if exposure has resulted in injury; (c) Follow-up investigations on all public resources documented to be injured by the spill to quantify the injury; (d) Quantification of damages for all public resources where injury has been quantified; and (e) Restoration/enhancement projects to compensate for public resource injuries to the extent technically feasible; and, for damages that cannot be compensated by technically feasible restoration or enhancement projects, implementation of projects/studies to compensate for these losses. Public resource restoration and enhancement projects and studies shall be prioritized as follows: (i) On-site, in-kind; (ii) Off-site, in-kind; (iii) On-site, out-of-kind; and (iv) Off-site, out-of-kind.

[Statutory Authority: Chapter 90.48 RCW. 92-10-005 (Order 91-13), § 173-183-260, filed 4/23/92, effective 5/24/92.] -------------------------------------------------------------------------------- 173-183-270 Participation. To efficiently implement WAC 173-183-250 the RDA committee may develop public resource damage assessment agreements to facilitate cooperation between state and federal agencies and Indian tribes. [Statutory Authority: Chapter 90.48 RCW. 92-10-005 (Order 91-13), § 173-183-270, filed 4/23/92, effective 5/24/92.] -------------------------------------------------------------------------------- 173-183-300 Purpose. The purpose of this section is to establish a compensation schedule that will provide a simple methodology for assessing damages to public resources from oil spills into fresh, marine, and estuarine waters of the state. The intent is to provide an alternate methodology to the extensive and expensive natural resource damage assessments presently being conducted following oil spills. This section provides the procedures for: (1) Establishing the relative vulnerability of public resources to oil spills by taking into consideration the relative toxicity of the oil spilled and the sensitivity of public resources present in the receiving environment; and (2) Determining adequate monetary compensation for injury to public resources resulting from an oil spill. [Statutory Authority: Chapter 90.48 RCW. 92-10-005 (Order 91-13), § 173-183-300, filed 4/23/92, effective 5/24/92.] -------------------------------------------------------------------------------- 173-183-310 Authority. This regulation implements the establishment of a resource damage compensation schedule consistent with the provisions of RCW 90.48.366 for the discharge of oil in violation of chapter 90.48 or 90.56 RCW which requires the department to establish the compensation schedule in consultation with the departments of fisheries, wildlife, and natural resources, and the parks and recreation commission, and with the assistance of a scientific advisory board. [Statutory Authority: Chapter 90.48 RCW. 92-10-005 (Order 91-13), § 173-183-310, filed 4/23/92, effective 5/24/92.] -------------------------------------------------------------------------------- 173-183-320 Compensation schedule. (1) The compensation schedule determines adequate compensation for unquantifiable damages or for damages not quantifiable at a reasonable cost for persons liable under RCW 90.48.142. (2) Adequate compensation as determined from the compensation schedule is derived from preexisting information of resource vulnerability to a class of oil spilled in a particular subregion of the state during a particular season, plus any additional information collected at the reconnaissance stage of the spill response. (3) Under RCW 90.48.366, the amount of compensation assessed under this schedule shall be no less than one dollar per gallon of oil spilled and no greater than fifty dollars per gallon of oil spilled. [Statutory Authority: Chapter 90.48 RCW. 92-10-005 (Order 91-13), § 173-183-320, filed 4/23/92, effective 5/24/92.] -------------------------------------------------------------------------------- 173-183-330 Resource damage assessment using the compensation schedule. The compensation schedule includes: (1) A relative ranking for each of the classes of oil defined in this chapter as determined by their known chemical, physical, and mechanical properties, and other factors that may affect the severity and persistence of the spill on the receiving environment; (2) A relative vulnerability ranking of receiving environments which takes into account location of the spill, habitat and public resource sensitivity to oil, seasonal distribution of public resources, areas of recreational use and aesthetic importance, the proximity of the spill to important habitats for birds, aquatic mammals, fish, or to species listed as threatened or endangered under state or federal law, and other areas of special ecological or recreational importance as determined by the department; (3) A quantitative method for determining public resource damages resulting from an oil spill, based on the oil effects and vulnerability rankings designed to compensate the people of this state for those damages that cannot be quantified at a reasonable cost that result from oil spills; and (4) A method for adjusting damages calculated under the compensation schedule based on actions taken by the potentially liable party that: (a) Demonstrate a recognition and affirmative acceptance of responsibility for the spill, such as the immediate removal of oil and the amount of oil removed from the environment; or (b) Enhance or impede the detection of the spill, the determination of the quantity of oil spilled, or the extent of damage, including the unauthorized removal of evidence such as injured fish or wildlife. [Statutory Authority: Chapter 90.48 RCW. 92-10-005 (Order 91-13), § 173-183-330, filed 4/23/92, effective 5/24/92.] -------------------------------------------------------------------------------- 173-183-340 Oil class ranking. (1) The purpose of this section is to provide a relative ranking of the severity of effects caused by a spilled oil. The ranking is based on the known chemical, physical, and mechanical properties of oils in the six classes identified in this section, as well as other properties affecting propensity to cause acute toxicity and mechanical injury, and to persist in the environment. For purposes of the compensation schedule, relative rankings of the severity of effects caused by a spilled oil are provided for the following classes of oils: (a) Prudhoe Bay crude oil; (b) Bunker C; (c) No. 2 fuel oil; (d) Gasoline; (e) Kerosene; and (f) Kerosene-type jet fuel. (2) The relative ranking scores for the oil classes range from 1 to 5, where 1 represents the least harmful effect and 5 represents the most harmful effect. For purposes of RCW 90.48.366 and 90.48.367, the acute toxicity, mechanical injury, and persistence relative ranking scores for the oils described by the classes enumerated in subsection (1) of this section shall be as follows: Table 1. Acute Toxicity, Mechanical Injury and Persistence Relative Ranking Scores for Classified Oils (OIL). Oil Class Acute Toxicity Mechanical Injury Persistence Prudhoe Bay Crude Oil 0.9 3.6 5 Bunker C 2.3 5.0 5 No. 2 Fuel Oil 2.3 3.2 2 Gasoline 5.0 1.0 1 Kerosene 1.4 2.4 1 Kerosene-type Jet Fuel 1.4 2.4 1 (3) In cases where the spilled oil is not described by any of the oil classes listed in subsection (1) of this section, or is a mixture of oils, the department shall determine the acute toxicity, mechanical injury, and persistence scores as follows: (a) By assigning the acute toxicity, mechanical injury, and persistence scores assigned to the oil class best describing the spilled oil from subsection (2) of this section; or (b) By using the following guidance to determine the acute toxicity, mechanical injury, and persistence relative ranking scores: (i) Acute toxicity relative ranking score. An acute toxicity raw score is determined by summing the weighted averages of the 1-, 2-, and 3-ringed aromatic compounds comprising the spilled oil and dividing this sum by 107, where aromatic compound composition is determined by percent-weight, and weighting is determined by aqueous solubility of the aromatic compounds, as described by the following formula: Acute Toxicity Raw Score = [(SOL1*PCT-WT1)(SOL2*PCT-WT2)(SOL3*PCT-WT3)]/107 where SOLi = solubility in seawater of i-ring aromatic hydrocarbons, and PCT-WTi = percent weight of i-ring aromatic hydrocarbons in the spilled oil, i = 1, 2, and 3. The final acute toxicity relative ranking score is determined by rounding the acute toxicity raw score to the nearest 0.1 using standard rounding procedures where decimals less than 0.05 are rounded down and decimals equal to or greater than 0.05 are rounded up. (ii) Mechanical injury relative ranking score. A mechanical injury raw score is determined by subtracting 0.688 from the specific gravity of the spilled oil and dividing this result by 0.062 as follows: Mechanical Injury Score = (SP - 0.688)/0.062 where SP = specific gravity of the spilled oil. The final mechanical injury ranking score is determined by rounding the mechanical injury raw score to the nearest 0.1 using standard rounding procedures where decimals less than 0.05 are rounded down and decimals equal to or greater than 0.05 are rounded up. (iii) Persistence relative ranking score. A persistence relative ranking score is determined from empirical data describing the length of time the spilled oil is known to, or is likely to, persist in a variety of habitat types. Scoring is assigned on a 1 to 5 scale as follows: SCORE ANTICIPATED PERSISTENCE 5 5 - 10 years or more 4 2 - 5 years 3 1 - 2 years 2 1 month to 1 year 1 days to weeks. (4) In cases where the spilled oil is comprised of two or more types of oil, damages shall be calculated under the schedule for each oil type and then summed to calculate total damages liability.

(1) The purpose of this section is to describe the method of ranking vulnerability of marine and estuarine environments, excluding the Columbia River estuary environment to oil spills for the purposes of assessing damages using the compensation schedule. (2) Marine and estuarine waters of the state excluding the Columbia River estuary are divided into sixteen regions and one hundred thirty-one subregions for purposes of RCW 90.48.366, as designated on the maps attached as Appendix 5 of this chapter. (3) A spill vulnerability score (SVS) shall be calculated at the time of a spill for the most sensitive subregion and season impacted by the spill. The SVS rates the vulnerability of public resources to spilled oil based on the propensity of the oil to cause acute toxicity and mechanical injury, and to persist in the environment. SVS is determined by summing the vulnerability scores for marine birds, marine mammals, fishery species, recreational use and habitats for the subregion(s) and most sensitive season impacted by the spill. The formula to be used to calculate SVS for each of the three oil effects, acute toxicity, mechanical injury, and persistence, is as follows: Spill vulnerability score (SVS)ij= HVSi BVSj MVSj MFVSj SFVSj SAVSj RVSj where HVSi = habitat vulnerability to oil's propensity to cause i BVS = marine bird vulnerability score (WAC 173-183-420(3)); MVS = marine mammal vulnerability score (WAC 173-183-460(3)); MFVS = marine fisheries vulnerability score (WAC 173-183-430(3)); SFVS = shellfish vulnerability score (WAC 173-183-440(3)); SAVS = salmon vulnerability score (WAC 173-183-450(5)); RVS = recreation vulnerability score (WAC 173-183-470(3)); i = acute toxicity (AT), mechanical injury (MI), or persistence (Per); and j = the most sensitive season affected by the spill: Spring, summer, fall, or winter [Statutory Authority: Chapter 90.48 RCW. 92-10-005 (Order 91-13), § 173-183-400, filed 4/23/92, effective 5/24/92.] -------------------------------------------------------------------------------- 173-183-410 Marine and estuarine habitat vulnerability. (1) The purpose of this section is to provide a marine and estuarine habitat vulnerability ranking. The marine and estuarine habitats present in the state are: (a) Classified into thirty-seven types based on substrate type, energy regime and depth of occurrence; and (b) Relatively ranked and scored for vulnerability to oil spills on a 1 to 5 scale, where a habitat vulnerability score (hv) of 5 represents the greatest vulnerability and an hv of 1 represents the least vulnerability. (2) Marine and estuarine habitat vulnerability scores (hv) are based on the following: (a) Presence of living public resources at risk, where living public resources include only those not otherwise incorporated into the compensation schedule in the marine fish, shellfish, salmon, marine mammal or marine bird vulnerability rankings of WAC 173-183-420 through 173-183-460; and (b) Predicted sensitivity to the acute toxicity, mechanical injury and persistence effects of oil based on energy regime of the habitat and propensity to entrain oil. (3) For purposes of RCW 90.48.366, marine and estuarine habitats of the state are classified into the following thirty-seven habitat types: (a) Marine intertidal habitats. (i) Exposed and semiexposed rocky shores. Bedrock and boulder habitats exposed to the full range of wave energies of the Pacific (i.e., on the outer coast), or to extensive wave fetch along the Strait of Juan de Fuca. Rocky areas on the coast partly protected behind sea stacks or islands also fall into this category. (ii) Sand-scoured rocky shores. Rocky headlands or sea stacks directly adjacent to high energy sandy beaches such that there is much suspended sand in the water, which scours the rock. Unique plants and animals are found here. (iii) Protected rocky shores. Bedrock and boulder habitats lacking oceanic swell and extensive wave fetch; e.g., inside waters of the San Juan Islands, headlands in bays off the Strait of Juan de Fuca or well protected behind islands on the outer coast. (iv) Semiexposed cobble and mixed-coarse beaches. Beaches exposed to moderate wave action composed of cobble overlying sand, or to somewhat less wave action, with a mix of cobble, gravel, and sand where no one component occupies more than seventy percent of the surface. Algae may grow on larger cobbles, and animals live both on the surface and in the sediment. Species vary dramatically with degree of wave exposure and composition of the sediment. Found inside the San Juan Islands, outside of Whidbey Island, at semiprotected sites along the Strait, and behind island and sea stacks on the coast. (v) Semiexposed gravel beaches. Unstable beaches, containing some sand in more protected areas. Many sites along the Strait of Juan de Fuca. (vi) Exposed sandy beaches. Pure marine sands found in moderate to high-energy areas, e.g., on the outer coast and along the Strait of Juan de Fuca. Mouths of bays with some wave action also fall into this category. (vii) Semiprotected mixed-fine beaches. Mixed sand and silt habitats, found in bays and inlets with some wave action so they are not dominated by the finer sediments (muds). Patches of gravel may be present high on the shore. (viii) Protected mud flats. Areas of little to no wave energy, where fine sediments settle and accumulate organic matter. Found in calm bays and inlets with little freshwater influx (i.e., not estuaries). (b) Marine subtidal. (i) Shallow subtidal rock and boulders. Areas less than 15 m depth with some currents so that sediments do not totally cover bedrock. Kelp beds are found in these habitats, which are widespread in the state. (ii) Deep subtidal rock and boulders. Areas deeper than 15 m and thus lacking in significant algal cover, but still with enough currents to keep the substrate exposed. Common in the San Juans and the Strait. (iii) Deep subtidal cobble and mixed-coarse areas. "Scoured" areas in channels or passes with high currents, composed entirely of cobbles or with gravel and sand mixed in. (iv) Shallow subtidal mixed-coarse to mixed-fine areas (low energy). Areas ranging from cobbles lying over a matrix of sand and gravel to mixed sand and silt, in waters less than 15 m. Bays and inlets commonly have this range of substrate types. Plants and animals exist both on the cobbles and in the sediment. (v) Shallow subtidal gravel or mixed-fine areas (high energy). Areas just offshore of sand or gravel beaches, where swells or wave action keep fine sediments from accumulating. Substrates range from pure gravel to gravel mixed with sand and shells. Common in the Strait. (vi) Deep subtidal sand. Areas deeper than 15 m in the Strait or on the coast where swells keep the substratum fairly coarse. (vii) Deep subtidal mixed-fine areas. Areas of sand, shells, and pebbles with some currents removing finer particles. (viii) Deep subtidal muddy areas. Areas with no swell and few currents, where fine silts settle out and accumulate organic matter. (ix) Open water. Areas deeper than 20 m. (c) Estuarine intertidal. (i) Open rocky shores. Rocky intertidal areas (including hardpan and riprap) in areas exposed to moderate waves or currents, e.g., on headlands in Puget Sound. (ii) Open mixed-coarse beaches. One of the most common beach types in Puget Sound, composed of a mix of cobble, gravel, and sand in areas with some wave action that keeps finer silts suspended. Sparse salt marsh vegetation may occur at the tops of these beaches, especially in quieter areas. (iii) Open gravel beaches. Areas of gravel or pebbles, often overlying sand, in areas of moderate wave action. (iv) Open sandy beaches. Common habitats of gently sloping beaches but moderate wave action. May have gravel on the upper shore. Found in Puget Sound and in some areas of other estuaries, including Grays Harbor. (v) Sandy low marshes. Found on spits, berms, and deltas where sand collects. Areas of different salinities are dominated by different marsh plant communities. Widespread (although disturbed) throughout the Puget Trough. (vi) Mixed-fine beaches and low marshes. Found in backwaters or deltas away from large channels, where the substrate is mixed sand and mud, sometimes with patches of gravel or peat. Substrate is stable and organic-rich. Marsh communities vary with salinity. (vii) Saline lagoons. Areas where water-borne sediments are deposited into a spit closing off an embayment, which is flushed regularly or irregularly. Salinities vary with evaporation and runoff but are generally high. (viii) Low-salinity lagoons. Lagoons that are nearly separated from tidal/salt influence by a berm, and where there is a source of freshwater. Substrate is usually soft silt. This habitat is rare in the state. (ix) Mud flats. Areas lacking in gravel or significant amounts of sand due to limited wave action, usually found in the heads of bays and inlets. Includes undisturbed channels and sloughs which drain slowly through a tidal cycle, and which may contain some sand. (x) High salt marshes. Areas above normal high water but salt influenced, with organic/peat substrata. Salinities vary, and plant communities with them. (xi) Transition zone wetland. Areas transitional between salt marshes and uplands, where salt water only rarely inundates. Substrata are peat or fine silts. (d) Estuarine subtidal. (i) Shallow subtidal rock and boulders. Areas less than 15 m deep with moderate currents or wave action that remove silt. Kelp beds develop here. (ii) Deep subtidal rock and boulders. Areas in narrow channels or around headlands where currents remove sediment that otherwise would settle in these deeper areas. These habitats are essentially marine, since freshwater tends to stay layered in shallow water. (iii) Shallow subtidal cobble and mixed-coarse areas. Mixed cobble, gravel, and sand remain in shallow areas fairly open to wave action or currents. (iv) Deep subtidal cobble and mixed-coarse areas. Tidal currents running through deep channels in Puget Sound keep fine silts from settling and create areas of mixed cobbles, sand, and gravel. (v) Shallow subtidal sandy or mixed-fine areas. High-current areas with little debris and some gravel, or less current-swept with more debris. Both are common outside of enclosed bays in Puget Sound. (vi) Deep subtidal sandy or mixed-fine areas. Current-swept areas below 15 m. Organic debris and gravel tend to accumulate deeper (below 30 m), leading to different assemblages there. (vii) Shallow subtidal muddy bays. Common habitats in open to partly enclosed bays in Puget Sound, where limited water movement allows fine sediments to accumulate. Organic enrichment is high, especially in more enclosed bays. (viii) Deep subtidal muddy bays. Habitats in the heads and centers of inlets in Puget Sound where there is little motion and the substrate is soft mud and sand. Assemblages vary with depth and amount of organic debris accumulated. (ix) Open water. Areas deeper than twenty meters. (4) For purposes of RCW 90.48.366, marine and estuarine habitat vulnerability scores (hv) for each of the habitat types classified in subsection (3) of this section shall be as follows: TABLE 2.

The habitat vulnerability for a particular habitat type and oil effect (hv) shall be multiplied by a factor of 1.5 for habitat types with seagrass or kelp present. The RDA committee shall be responsible for determining whether seagrass or kelp are present in a habitat type, and the portion of a habitat type containing seagrass or kelp. (6) In general, several of the habitat types classified in this section may be affected by a particular spill. The habitat vulnerability score for a particular spill and oil effect (HVSi) is composite of the habitat vulnerability scores for each of the habitat types affected by the spill which takes into consideration the percent coverage of each habitat type in the area of spill impact. (7) The habitat vulnerability score for a particular spill and oil effect (HVS) shall be determined as follows: (a) For spills of 1,000 gallons or more. Sum the weighted habitat vulnerability scores for each habitat type exposed to the spill as described by the formula provided in (c) of this subsection, where weighting is defined by percent coverage of each habitat type within the area of spill exposure. (b) For spills of less than 1,000 gallons. Sum the weighted habitat vulnerability scores for each habitat type present in the subregion(s) exposed to the spill as described by the formula provided in (c) of this subsection, where weighting is defined by percent coverage of each habitat type present in the subregion(s) exposed to the spill. (c) The formula to calculate the raw habitat vulnerability score for a particular spill and oil effect (HVSi) is as follows: HVSi = |nj=1 (hvij x PCj) where PCj = Percent-coverage of habitat-type j expressed as a decimal; hvij = habitat vulnerability for a particular habitat type & oil effect; j = habitat type; i = acute toxicity (AT), mechanical injury (MI) and persistence (PER); and n = number of habitats to be considered as determined under (a) and (b) of this subsection. (d) The final HVSAT, HVSMI, and HVSPER scores are found by rounding the raw scores calculated from the formula in (c) of this subsection to the nearest 0.01 as follows: Decimals less than 0.005 shall be rounded down and decimals equal to or greater than 0.005 shall be rounded up.

(1) Each of the marine and estuarine subregions of state waters established in WAC 173-183-400(2) is relatively ranked and scored for marine bird vulnerability to oil spills on a 1 to 5 scale for each season, where a score of 5 represents the greatest vulnerability and a score of 1 represents the least vulnerability. (2) The marine bird vulnerability ranking relatively ranks the vulnerability of seabirds, shorebirds, and waterfowl present in a subregion during a particular season to oil spills, where vulnerability is based on population status, abundance, roosting habits, escape behavior, flocking behavior, feeding specialization, population size, reproductive capacity, breeding dispersion, winter dispersion, seasonal exposure to waters where oil spills could occur, and significance of Washington population to total population. (3) Marine bird seasonal vulnerability scores for each of the marine and estuarine subregions defined in WAC 173-183-400 are based on existing information and determinations made by the marine bird subcommittee of the scientific advisory board. For purposes of RCW 90.48.366, marine bird seasonal vulnerability scores (BVS) for each of the subregions defined in WAC 173-183-400 shall be as follows: Table 4.

(4) From the information enumerated in subsection (2) of this section, the RDA committee shall determine the species/year class vulnerability score for a spill (SAVSi) by summing the weighted species/year class vulnerability scores for each of the salmon vulnerability habitats classified in Table 8 of subsection (2) of this section, where weighting is defined as percent-coverage of the salmon vulnerability habitats as determined in subsection (3) of this section, as follows: SAVSi = (savs1* PCT-COV1) (savs2* PCT-COV2) ... (savsn* PCT-COVn) where SAVSi = salmon vulnerability score for a species/year class; savsj = species/year class habitat vulnerability score for the season of greatest spill impact from subsection (2) of this section; PCT-COVj = percent-coverage of habitat j from subsection (2) of this section; i = Chinook, subyearling (Cs); Chinook, yearling (Cy); Coho (C); Pink (P); Chum (Ch); and Sockeye (So); and n = the number of salmon vulnerabililty habitats used to calculate SAVS as determined in subsection (3) of this section. (5) The raw salmon vulnerability score for a spill (SAVSs) shall be calculated as follows: (a) In years when pink salmon are present in state waters. The chinook salmon spill vulnerability scores for subyearlings (SAVSCs) and yearlings (SAVSCy) as determined in subsection (4) of this section shall be averaged, then added to the spill vulnerability scores for coho (SAVSC), pink (SAVSP), chum (SAVSCh) and sockeye (SAVSSo) salmon as determined in subsection (4) of this section. The sum of these scores shall then be divided by 5, as described by the following formula: SAVSs = [(SAVSCs SAVSCy)/2 SAVSC SAVSP SAVSCh SAVSSo]/5 where SAVSs = salmon vulnerability score for a spill; SAVSCs = chinook, subyearling vulnerability score from subsection (4) of this section; SAVSCy = chinook (yearling) vulnerability score from subsection (4) of this section; SAVSC = coho salmon vulnerability score from subsection (4) of this section; SAVSP = pink salmon vulnerability score from subsection (4) of this section; SAVSC = chum salmon vulnerability score from subsection (4) of this section; SAVSSo = sockeye salmon vulnerability score from subsection (4) of this section; (b) In years when pink salmon are not present in state waters. The chinook salmon spill vulnerability scores for subyearlings (SAVSCs) and yearlings (SAVSCy) as determined in subsection (4) of this section shall be averaged, then added to the spill vulnerability scores for coho (SAVSC), chum (SAVSCh) and sockeye (SAVSSo) salmon as determined in subsection (4) of this section. The sum of these scores shall then be divided by 4, as described by the following formula: SAVSs = [(SAVSCs SAVSCy)/2 SAVSC SAVSCh SAVSSo]/4 where SAVSs = salmon vulnerability score for a spill; SAVSCs = chinook, subyearling vulnerability score from subsection (4) of this section; SAVSCy = chinook (yearling) vulnerability score from subsection (4) of this section; SAVSC = coho salmon vulnerability score from subsection (4) of this section; SAVSP = pink salmon vulnerability score from subsection (4) of this section; SAVSC = chum salmon vulnerability score from subsection (4) of this section; SAVSSo = sockeye salmon vulnerability score from subsection (4) of this section; (6) If spilled oil enters a river mouth, SAVSi from subsection (4) of this section shall be assigned a score of 5 for each species/year class in peak occurrence in a river mouth during the period of time the spilled oil enters and remains in the river mouth. Scores of 5 determined for species/year classes under this subsection shall supersede SAVSi scores calculated under subsection (4) of this section. The RDA committee shall make determinations of whether oil enters a river mouth and whether species/year classes are in peak occurrence when spilled oil is present in a river mouth. (7) The final SAVSs score is found by rounding the raw SAVSs score calculated in subsection (5) of this section to the nearest 0.01 as follows: Decimals less than 0.005 shall be rounded down and decimals equal to or greater than 0.005 shall be rounded up. (8) The final salmon vulnerability score for a spill shall be multiplied by 1.5 when any number of individuals of state or federal threatened or endangered salmon races and/or runs are exposed to spilled oil.

(1) The purpose of this section is to describe the method of ranking vulnerability of the Columbia River estuary environment to oil spills for purposes of assessing damages using the compensation schedule. (2) The Columbia River estuary has been distinguished from other estuarine waters of the state because it resides within the jurisdiction of two states, Washington and Oregon. (3) For purposes of RCW 90.48.366, estuarine waters of the Columbia River are divided into one kilometer square cells. Bird, fish, mammal, invertebrate, habitat, and human use resource sensitivity have been evaluated for each cell by season. Seasonal resource sensitivities are ranked for each cell on a 1 to 5 scale where 5 represents the greatest sensitivity and 1 represents the least sensitivity as designated on the maps attached as Appendix 6 of this chapter. (4) A vulnerability score (VS) shall be calculated at the time of a spill for each cell and for the most sensitive season impacted by the spill. The VS rates the vulnerability of public resources to the spilled oil. (a) VS for a particular cell is determined by summing the sensitivity scores assigned to each cell for bird, fish, mammal, invertebrate, habitat, and human use resources as follows: VSij = BSSij FSSij MSSij ISSij HSSij HUSij where VSij = spill vulnerability score for a particular call and season BSS = bird sensitivity score (from Appendix 6 of this chapter) FSS = fish sensitivity score (from Appendix 6 of this chapter) MSS = mammal sensitivity score (from Appendix 6 of this chapter) ISS = invertebrate sensitivity score (from Appendix 6 of this chapter) HSS = habitat sensitivity score (from Appendix 6 of this chapter) HUS = human use sensitivity score (from Appendix 6 of this chapter) i = the cell under consideration j = the most sensitive season impacted; fall, winter, spring, or summer (b) The raw vulnerability score for a spill (SVS) is determined by calculating the average of the vulnerability scores for the cells exposed to the spill as follows: SVSj = (VS1 VS2 ... VSx)/x where VSi = vulnerability score for cell i (from subsection (4)(a) of this section), x = number of cells exposed to the spill, and (5) The final SVS score is found by rounding the raw SVS score calculated from the formula in subsection (4) of this section to the nearest 0.01 as follows: Decimals less than 0.005 shall be rounded down and decimals equal to or greater than 0.005 shall be rounded up. [Statutory Authority: Chapter 90.48 RCW. 92-10-005 (Order 91-13), § 173-183-500, filed 4/23/92, effective 5/24/92.] -------------------------------------------------------------------------------- 173-183-600 Vulnerability of freshwater stream, river, and lake environments to oil spills. (1) The purpose of this section is to describe the method of ranking the vulnerability of state freshwater stream, river, and lake environments, and portions thereof, to oil spills for purposes of applying the compensation schedule. (2) Vulnerability of freshwater stream, river, and lake environments to oil spills is based on water type classifications and a habitat index. (3) For each oil spill into a freshwater stream, river, or lake, a spill vulnerability score (SVS) is calculated. The SVS rates the vulnerability of public resources to spilled oil based on the spilled oil's propensity to cause acute toxicity, mechanical injury, and to persist in the environment. SVS is determined by multiplying the freshwater vulnerability score, which is based on the water type classification, by the habitat index score as described by the following formula: Raw Spill Vulnerability Score (SVS)= FVS* HI. where FVS = Freshwater vulnerability score (from WAC 173-183-610), and HI = Habitat index (from WAC 173-183-620). (4) The final SVS score is found by rounding the raw SVS score calculated from the formula in subsection (3) of this section to the nearest 0.01 as follows: Decimals less than 0.005 shall be rounded down and decimals equal to or greater than 0.005 shall be rounded up.

(1) For purposes of this chapter, freshwater streams, rivers, lakes, and portions thereof, are classified into 5 water types based on the identification system set forth in WAC 222-16-030 which is incorporated by reference. (a) "Type 1 Water" means all waters, within their ordinary high-water mark, as inventoried as "shorelines of the state" under chapter 90.58 RCW. (b) "Type 2 Water" shall mean segments of natural waters which are not classified as Type 1 Water and have a high use and are important from a water quality standpoint for: (i) Domestic water supplies; (ii) Public recreation; (iii) Fish spawning, rearing, or migration or wildlife uses; or (iv) Are highly significant to protect water quality. (c) "Type 3 Water" shall mean segments of natural waters which are not classified as Type 1 or 2 Water and have a moderate to slight use and are moderately important from a water quality standpoint for: (i) Domestic water supplies; (ii) Public recreation; (iii) Fish spawning, rearing, or migration or wildlife uses; or (iv) Are highly significant to protect water quality. (d) "Type 4 Water" shall mean segments of natural waters which are not classified as Type 1, 2, or 3. Their significance lies in their influence of water quality downstream in Type 1, 2, or 3 Waters. These may be perennial or intermittent. (e) "Type 5 Water" means all other waters, in natural water courses, including streams with or without a well-defined channel, areas of perennial or intermittent seepage, ponds, and natural sinks. Drainage ways having short periods of runoff are considered to be Type 5 Waters. (3) The vulnerability of freshwater environments is based on the stream typing system established in WAC 222-16-030 incorporated by reference. The rating of biological and recreational resources ranges from 1 to 5 where 5 represents the most sensitive category and 1 represents the least sensitive category as follows: TABLE 11. Freshwater Vulnerability Score (FVS). FVS QUALIFICATION 5 "Type 1 waters" 4 "Type 2 waters" 3 "Type 3 waters" 2 "Type 4 waters" 1 "Type 5 waters" [Statutory Authority: Chapter 90.48 RCW. 92-10-005 (Order 91-13), § 173-183-610, filed 4/23/92, effective 5/24/92.] -------------------------------------------------------------------------------- 173-183-620 Habitat index. (1) Most state freshwaters vary to some degree from the natural condition as increased activities within individual watersheds have decreased stream, river, and/or lake habitat quality. In order to account for that degradation prior to assessing damages using the compensation schedule, a habitat index (HI) is calculated to represent existing stream conditions prior to the oil spill. (2) For each stream, river, or lake impacted by an oil spill where the preassessment screening committee determines that the compensation schedule shall be used, a habitat index (HI) shall be calculated following an oil spill using the following methodology. The HI measures the amount of stream degradation from natural conditions and shall be calculated using the following formula: Habitat Index (HI) = [(P123456)÷Np] x f1 x f2 x f3 where: P1 = barriers to natural fish movement P2 = urbanization P3 = condition of riparian vegetation P4 = condition of floodplain P5 = land use of watershed P6 = flow alteration Np = number of P parameters used to calculate HI f1 = channel modifications f2 = impoundment f3 = water quality (3) The RDA committee shall determine which of the habitat quality parameters described in subsection (2) of this section are applicable to the particular spill under consideration. If a parameter is not applicable to the spill under consideration, the parameter shall not be included in the formula provided in subsection (2) of this section. (4) Habitat quality parameters (P). (a) Barriers to natural fish movement (P1). Barriers, to some degree, limit the free passage of fish upstream thus limiting the ability of streams to recover. The scoring of this parameter is based on the influence of barriers in the natural dispersal of fish populations as follows: Table 12. Scoring of Barriers to Natural Fish Movement (P1). RATING QUALIFICATION 10 No manmade obstructions to free upstream passage of fish 8 No dams or other structures causing a vertical drop of more than 1 foot during low flow 5 No dams or other structures causing a vertical drop of more than 3 foot during low flow 3 No dams or other structures causing a vertical drop of more than 10 foot during low flow 0 One to several dams or other structures each causing a drop of more than 10 feet during low flow (b) Urbanization (P2). Urban development has historically had negative habitat effects on freshwater ecosystems. The percent of urban development in a watershed directly influences siltation, riparian abuse, and water quality deterioration. The scoring of this parameter is based on the percent of urbanization in the stream watershed. Table 13. Scoring of Urbanization (P2). RATING QUALIFICATION 10 Less than 5 percent of the watershed in urban development 8 Five to 10 percent of the watershed in urban development 5 Ten to 40 percent of the watershed in urban development 3 Forty to 70 percent of the watershed in urban development 0 Seventy to 100 percent of the watershed in urban development (c) Condition of riparian vegetation (P3). Riparian vegetation is important to seventy percent of the animal and bird species in Washington for some part of their life cycle. It also exerts thermal regulatory and thermal controls for the aquatic system. The scoring of this parameter is based on the percent of banks that are protected by effective riparian vegetation. Table 14. Scoring of Condition of Riparian Vegetation (P3). RATING QUALIFICATION 10 Ninety to 100 percent of the banks are protected by appropriate perennial vegetation 8 Sixty to 90 percent of the banks are protected by appropriate perennial vegetation 5 Forty to 60 percent of the banks are protected by appropriate perennial vegetation 3 Ten to 40 percent of the banks are protected by appropriate perennial vegetation 0 Zero to 10 percent of the banks are protected by appropriate perennial vegetation (d) Condition of the floodplain (P4). The condition of the floodplain forecasts the amount of sedimentation and erosion in the watershed and as such is a primary predictor of stream degradation. The rating of this parameter is as follows: Table 15. Scoring of the Condition of the Floodplain (P4). RATING QUALIFICATION 10 Little or no evidence of active or recent erosion of the floodplain during floods 5 All segments show evidence of occasional erosion of the floodplain. Stream channel essentially intact 0 Floodplain severely eroded and degraded, stream channel poorly defined with much lateral erosion and much reduced flow capacity (e) Land use of the watershed (P5). Land use practices exert a great deal of influence on the quality of the aquatic habitat. The rating of this parameter is as follows: Table 16. Scoring of Land Use of the Watershed (P5). RATING QUALIFICATION 10 More than 80 percent of the watershed protected by timber, improved pasture, terraces, or other conservation practices 8 Sixty to 80 percent of the watershed protected by timber, improved pasture, terraces, or other conservation practices 5 Forty to 60 percent of the watershed protected by timber, improved pasture, terraces, or other conservation practices 3 Twenty to 40 percent of the watershed protected by timber, improved pasture, terraces, or other conservation practices 1 Zero to 20 percent of the watershed protected by timber, improved pasture, terraces, or other conservation practices (f) Flow alteration (P6). Alteration of the natural flow regime can frequently alter habitat conditions that are necessary for certain behavioral and ecological needs of species. The rating of this parameter is as follows: Table 17. Scoring for Flow Alteration (P6). RATING QUALIFICATION 10 Less than 1 percent of the watershed controlled by impoundments and/or less than 50 percent of the watershed controlled by farm ponds 8 One to 30 percent of the watershed controlled by impoundments and/or less than 50 percent of the watershed controlled by farm ponds 5 Thirty to 60 percent of the watershed controlled by impoundments and/or less than 50 percent of the watershed controlled by farm ponds 3 Sixty to 95 percent of the watershed controlled by impoundments and/or less than 50 percent of the watershed controlled by farm ponds 0 Ninety-five to 100 percent of the watershed controlled by impoundments and/or less than 50 percent of the watershed controlled by farm ponds (5) Habitat alteration functions (F). Each habitat alteration function has the power to reduce the habitat quality rating, dependent on the type and extent of alteration. Functions are expressed on a scale of 0 to 1.0.

(1) The purpose of this section is to describe the method of ranking the vulnerability of freshwater wetland environments to oil spills for purposes of assessing damages by applying the compensation schedule. (2) Vulnerability of freshwater wetland environments to oil spills is based on a wetlands classification which rates the vulnerability of a wetland to spilled oil. Wetland environments are classified into five categories which represent the sensitivity of habitat, plants, animals, and recreational use to oil spills. For purposes of this chapter, the wetlands vulnerability score shall be equal to the spill vulnerability score as follows: Spill Vulnerability Score (SVS) = WVS where WVS = wetlands vulnerability score (from WAC 173-183-710).
