Effective Date of Rule: Thirty-one days after filing.

     Purpose: The purpose of this rule is to amend the compensation schedule mathematical formula multipliers in regulation so that the full range of compensation ($1 to $100 per gallon of oil spilled) required in state law can be calculated. This rule will amend WAC 173-183-830(3), 173-183-840(2), 173-183-850(2), and 173-183-860(2), by replacing current multipliers with new multipliers that are capable of achieving the full range of compensation required in state law. This rule will also change WAC 173-183-830(3), 173-183-840(2), 173-183-850(2), and 173-183-860(2) by replacing the $50 ceiling limit value with the new $100 ceiling limit required by RCW 90.48.366.

AMENDATORY SECTION(Amending Order 03-03, filed 5/12/03, effective 6/12/03)

WAC 173-183-830   Calculation of damages for spills into marine and estuarine waters, except the Columbia River estuary.   (1) The formula provided in subsection (2) of this section shall be used to determine damages liability for spills into marine and estuarine waters, except the estuarine waters of Columbia River. The value of the variables used in the formula shall be determined by:

     (a) The OSC as enumerated in WAC 173-183-810(1);

     (b) The mutually agreed upon independent expert, if applicable, as described in WAC 173-183-810(2); and

     (c) The RDA committee chair as enumerated in WAC 173-183-820 (1)(a).

     (2) In making the determination of percent-coverage of habitat types, the RDA committee chair may assume that the habitat-type visible at low tide extends out to the 20 meter depth contour.

     (3) Damages liability shall be calculated using the following formula:

Damages ($) =
		gallons spilled* ((0.1)) 0.208* [(OILAT*SVSAT,j) +
		(OILMI*SVSMI,j) + (OILPER*SVSPER,j)]
where:		gallons spilled = the number of gallons of oil spilled as determined by the procedures outlined in WAC 173-183-810;
		SVSi,j = spill vulnerability score (from WAC 173-183-400(3));
		OILAT = Acute Toxicity Score for Oil (from WAC 173-183-340);
		OILMI = Mechanical Injury Score for Oil (from WAC 173-183-340); and
		OILPER = Persistence Score for Oil (from WAC 173-183-340).
		i = acute toxicity, mechanical injury and persistence effect of oil
		j = the most sensitive season affected by the spill
		((0.1)) 0.208 = multiplier to adjust the damages calculated to the $((1-50)) 1-100 per gallon range.

     Formula results shall be rounded to the nearest 0.01 to determine damages liability as follows: Decimals less than 0.005 shall be rounded down, and decimals equal to or greater than 0.005 shall be rounded up.

     (c) The RDA committee chair as enumerated in WAC 173-183-820 (1)(b).

     (2) Damages liability shall be calculated using the following formula:

Damages ($) =
		gallons spilled* ((0.2)) 0.508*SVSj*(OILAT+OILMI+OILPER)
where:		gallons spilled = the number of gallons of oil spilled as determined by procedures outlined in WAC 173-183-810

		SVS = Spill vulnerability score [from WAC 173-183-600(3)];
		OILAT = Acute Toxicity Score for Oil [from WAC 173-183-340];
		OILMI = Mechanical Injury Score for Oil [from WAC 173-183-340]; and
