| Pollutant: | Metals |
| Final Listing Decision: | List on 303(d) list (being addressed by action other than TMDL) |
| Last Listing Cycle's Final Listing Decision: | List on 303(d) list (being addressed by action other than TMDL)(2016) |
| Revision Status | Original |
| Sources: | A Source Unknown |
| Expected Attainment Date: | 2019 |
| Implementation Action Other than TMDL: | An alternative enforceable program, which is the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), is in place that will address metals and other acid mine drainage associated with the exceedance of water quality standards for this water segment. In May 2000, the USEPA placed the Leviathan mine on the CERCLA National Priorities List (NPL), thus making Leviathan mine a Superfund site. The cleanup process at Leviathan mine is required to meet all environmental requirements, or ARARs (applicable or relevant and appropriate requirements) during its operation. The Leviathan mine is in the Remedial Investigation/Feasibility Study stage of the CERCLA process. A Record of Decision is expected in 2010. |
| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Conclusion: | Regional Board Conclusion:
This pollutant was considered for placement on the section 303(d) list in a previous assessment cycle. No new information was reviewed for this current assessment cycle. Therefore, the previous conclusion remains unchanged, and is as follows: This water segment is being considered for listing under section 2.2 of the Listing Policy. Under this section of the Policy, a minimum of one line of evidence is needed to assess listing status. An alternative enforceable program Comprehensive Environmental Response, Compensation, and Liability Act is in place that will address metals and other acid mine drainage associated with the exceedances of water quality standards for this water segment. Based on the readily available information, the weight of evidence indicates that there is sufficient justification in favor of placing this water segment-pollutant combination in the Water Quality Limited Segments Being Addressed portion of the section 303(d) list. |
