A. For Ag, Hg, Pb, and IR, assign a rank to each station from 1 to 26 with rank of 1 going to the station with the highest metal or IR concentration. B. In case of ties (two or more observations having exactly the same value), assign an average rank following Conover (1971). C. To avoid weighting the metals more heavily than the IR, average the ranks for the three metals to obtain a mean metal rank. D. Based on mean metal rank, rerank stations to get composite metal rank. E. Average composite metal rank and IR rank to get mean metal -IR rank. F. Based on mean metal -IR ranks, rerank stations from 1 to 26 to get overall rank. G. Use overall rank for station selection. II. Procedures for station selection from urban bays aim to select the "hottest" stations based on the chemical data. A. Based on the overall ranks from above, select the top ten stations, i.e., those with ranks 1 -10. (This was later reduced to eight). B. In selecting stations from the urban bays, do not pass over any station because of sediment type or other character- istics. C. After station selection, determine the number of stations for all four bays falling within each class of sediment type: clayey -mud, silty -mud, sandy -silt, silty -sand, and (Table A -18). III. Procedures for station selection for the baseline bays aim to select the "cleanest" stations with the constraint that the distribution of sediment types for the baseline bays be similar to that for the urban bays. A. Determine number of stations required for each sediment type from distribution found for urban bays. B. Target is five (this was later reduced to four) stations per baseline bay, but allow some variation in number taken per bay in order to achieve desired sediment type distribution. C. Using overall ranks as determined under I. above, start selection at the "cleanest" station, i.e., start with the station ranked 20 and work upward. D. In working upward from rank 20, pass over those stations where: 1. The station's sediment type is not required, e.g., sand is a type not among those selected from the urban bays. 2. The station has a sediment type for which the quota is already filled, e.g., if all the required silty muds have been selected, pass over the remaining silty muds in favor of a different sediment type. E. After choosing five stations from each baseline bay, determine the resulting distribution of sediment types and compare it with urban bays. F. If the number of stations with a given sediment type is less than the required, reapportion number selected from each baseline bay. A.10 TABLE A -9.

Footnotes and other Details a (1) Sediment bioassays were conducted according to the general method of Swartz et al. (1985). Amphipod repsonses were measured following, a 10 -day exposure to sediments at 15T, under continuous illumination (10 -70 ft -c) and aeration. The salinity of the overlying water was 28.0 0 /oo. (2) During the assay of Elliott Bay and Dabob Bay sediments (Assays 6 & 7) aeration was interrupted for about 24 hours as a result of a power failure. Dissolved oxygen concentrations measured in representative test beakers at the end of the power failure ranged from 5.3 -6.4 mg /liter. This temporary interruption of the air supply did not appear to have adversely attected the outcome of the assays. (3) Sediments tested, during Assays 1, 2, 3, 4, and 5 were placed in a 4 -liter glass beaker and mixed with a plastic spoon before being added to the test beakers. Sediments tested during Assays 6, 7, and 8 were added to the test beakers after being mixed directly in the sample jars with an electric stirrer. The stirrer was equipped with a stainless steel shaft and n propeller. J b Insufficient free water to snake a salinity determination. c Amphipod survival in Assay No. 7 control sediment was unacceptably low in three of the five control replicates tested. Because similar excessive toxicity was not observed in any of the other samples tested, the unidentified contaminant appeared to have been primarily restricted to control replicates 1, 2, and 3. Consequently, the results of Assay No. 7 were not considered to be totally invalid, although retesting of the samples would be desirable.
