Pollutant: | Indicator Bacteria |
Final Listing Decision: | List on 303(d) list (being addressed by USEPA approved TMDL) |
Last Listing Cycle's Final Listing Decision: | Do Not List on 303(d) list (TMDL required list)(2012) |
Revision Status | Revised |
Sources: | Source Unknown |
TMDL Name: | Bacteria Impaired Waters I (creeks and beach shorelines) |
TMDL Project Code: | 169 |
Date TMDL Approved by USEPA: | 06/22/2011 |
Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | This pollutant is being considered for placement on the CWA section 303(d) List under section 3.2 of the Listing Policy. Under section 3.2 a single line of evidence is necessary to assess listing status.
Fourteen lines of evidence are available in the administrative record to assess this pollutant. With the latest data, 29 of 146 geomean samples exceed the water quality objective for total coliform for the protection of SHELL beneficial use. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification in favor of placing this water segment-pollutant combination on the CWA section 303(d) List. This conclusion is based on the staff findings that: 1. The data used satisfies the data quality requirements of section 6.1.4 of the Policy. 2. The data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 3. With the latest data, 29 of 146 geomean samples exceed the water quality objective for total coliform for the protection of SHELL beneficial use and this exceeds the allowable frequency listed in Table 3.2 of the Listing Policy. 4. Pursuant to section 3.11 of the Listing Policy, no additional data and information are available indicating that standards are not met. |
Regional Board Decision Recommendation: | After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be placed on the section 303(d) list because applicable water quality standards are exceeded and a pollutant contributes to or causes the problem. |
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. |

Analyzing only storm water bacteria data is important because the majority of beach monitoring data covers the months of April through October. The data may not capture the full impacts of seasonal storm events and high bacteria levels due to storm water runoff because much of the wet season for Southern California occurs in November through March. |

DECISION ID |
49383 |
Region 9 |
Pacific Ocean Shoreline, San Diego HU, at Stub Jetty, south of the San Diego River outlet, near Cape May Avenue |
||
Pollutant: | Trash |
Final Listing Decision: | List on 303(d) list (being addressed by action other than TMDL) |
Last Listing Cycle's Final Listing Decision: | New Decision |
Revision Status | Revised |
Sources: | Source Unknown |
Expected Attainment Date: | 2025 |
Implementation Action Other than TMDL: | The new trash control objectives apply. The trash found at this site, during cleanups that occurred on 11/22/08 and 11/28/09, are considered exceedances. The objectives are implemented as a conditional prohibition of discharge. Trash control amendments are the regulatory actions to be taken.
Collected effort of public, agencies, organizations, and permittees. Methods include street sweeping, education programs on littering, installation of trash-catching devices on storm drains |
Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | This pollutant is being considered for placement on the CWA section 303(d) List under section 3.7 of the Listing Policy. Under this section when all other listing factors do not result in the listing of a water segment but information indicates non-attainment of standards, a water segment shall be evaluated to determine whether the weight of evidence demonstrates that water quality standard is not attained. If the weight of evidence indicates non-attainment, the water segment shall be placed on the CWA section 303(d) List.
Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification for placing this water segment-pollutant combination from the CWA section 303(d) List. This conclusion is based on the staff findings that: 1. The data used satisfies the data quality requirements of section 6.1.4 of the Policy. 2. The following information indicates that the water quality standard is not being attained: Coastkeeper cleanups occurred on 11/22/08 and 11/28/09 for this water body. The total weight of trash (lbs) collected on these dates was 748.25. Using the metric, Coastkeeper classified this water body as medium for trash impairment. However, any trash found is an exceedance and needs to be addressed by an action other than a TMDL. 3. This process is scientifically defensible and reproducible. |
Regional Board Decision Recommendation: | After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be placed on the section 303(d) list because applicable water quality standards are exceeded and a pollutant contributes to or causes the problem. |
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. |
