| Compound | 4-day Average (CCC)1 | 1-hr Average (CMC)2 | Extent of Applicability |
|---|---|---|---|
| Copper | 6.9 | 10.8 | Marine and Estuarine Waters Contiguous to SF Bay, South of Dumbarton Bridge |
| Nickel | 11.9 | 62.4* | Marine and Estuarine Waters Contiguous to SF Bay, South of Dumbarton Bridge |
*Handbook of WQS, 2nd ed. 1994 in Section 3.7.6 states that the CMC = Final AcuteValue/2; 62.4 is the Final Acute Value (resident species database)/2; so the site-specific CMC is lower than the California Toxics Rule value because we are using the resident species database instead of the National Species Database.
