Region 9 |
Mission Bay Shoreline, at Enchanted Cove |
||
| Pollutant: | Trash |
| 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: | 2029 |
| Implementation Action Other than TMDL: | 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 5/24/08, 5/23/09, and 5/22/10 for this water body. The total weight of trash (lbs) collected on these dates was 2,064.25. However, using the metric, Coastkeeper classified this water body as severe 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. |

| Data Used to Assess Water Quality: | The San Diego Coastkeeper conducts trash cleanups and uses a metric (pounds of trash collected per volunteer) to compare levels of trash across beaches and categorizes beaches as either low, medium, high or severe, based on this metric. Coastkeeper cleanups occurred on 5/24/08, 5/23/09, and 5/22/10 for this water body. The total weight of trash (lbs) collected on these dates was 2,064.25. However, using the metric, Coastkeeper classified this water body as severe for trash impairment. | ||||
