Region 1 |
Klamath River HU, Tule Lake and Lower Klamath Lake National Wildlife Refuge |
||
| Pollutant: | pH (high) |
| Final Listing Decision: | List on 303(d) list (being addressed by USEPA approved TMDL) |
| Last Listing Cycle's Final Listing Decision: | List on 303(d) list (TMDL required list)(2006) |
| Revision Status | Original |
| Sources: | Internal Nutrient Cycling (primarily lakes) | Nonpoint Source |
| TMDL Name: | Lower Lost River |
| TMDL Project Code: | 99 |
| Date TMDL Approved by USEPA: | 12/30/2008 |
| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Conclusion: | 303(d) listing decisions made prior to 2006 were not held in an assessment database. The Regional Boards will update this decision when new data and information become available and are assessed.
The "Lost River, California Total Maximum Daily Loads Nitrogen and Biochemical Oxygen Demand to Address Dissolved Oxygen and pH Impairments" was established by the USEPA on December 30, 2008. 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. |
| Regional Board Decision Recommendation: | No new data were assessed for 2008. The decision has not changed, expect to add the completion date for the Lost River TMDLs. |
| State Board Review of Regional Board Conclusion and Recommendation: | |
| State Board Decision Recommendation: | After review of this Regional Board decision, SWRCB staff recommend the decision be approved by the State Board. |
