Pine Creek (Lassen County) |

| Pollutant: | Sedimentation/Siltation |
| Final Listing Decision: | Delist from 303(d) list (TMDL required list) |
| Last Listing Cycle's Final Listing Decision: | Delist from 303(d) list (TMDL required list)(2010) |
| Revision Status | Original |
| Reason for Delisting: | Applicable WQS attained; reason for recovery unspecified |
| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Staff Conclusion: | Regional Board Conclusion:
This pollutant was considered for removal from 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: Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification in favor of removing this water segment-pollutant combination from the section 303(d) list in the Water Quality Limited Segments category. This conclusion is based on the staff findings that the original Sedimentation/Siltation listing basis is faulty due to the fact that the real problem was fish passage issues, which is not a pollutant. Additionally the fish passage issue has been addressed through a CRMP. |
| Regional Board Staff Decision Recommendation: | No new data were assessed for this assessment cycle. The conclusion reached in the previous cycle remains in same. The Regional Board will update this decision when new data and information become available in a future assessment cycle. |

| Data Used to Assess Water Quality: | Pine Creek was listed due to lack of access to spawning habitat for Eagle Lake Trout (ELT). The "sedimentation/siltation" designation was apparently an artifact of an old 303(d) listing database, which provided a "picklist" of pollutants to select from. Since "lack of fish passage" was not an available option in the picklist, sedimentation/siltation was selected as the descriptor.
A Coordinated Resource Management Planning (CRMP) Group was formed in 1987, and as of 1997, over forty restoration projects to address habitat degradation and fish passage issues were completed (see Macdonald, 2000). In 1999, to address the lack of access to ELT spawning habitat, Caltrans agreed to replace the existing culverts on Highway 44 with ones that provide fish passage. The project also helped restore Pine Creek in its original channel. In 2000, a report summarizing current conditions and proposing delisting of Pine Creek was completed and accepted by USEPA as a TMDL-funded work product. The delisting was not acted on in 2000 due to a request by the CRMP to leave it on the list to secure funding. Regional Board staff recommends that Pine Creek be delisted as outlined in the 2000 delisting report. |
