San Diego Bay Shoreline, at Harbor Island (East Basin) |
||
Pollutant: | Copper |
Final Listing Decision: | Do Not Delist from 303(d) list (associated with a USEPA accepted Advanced Restoration Plan) |
Last Listing Cycle's Final Listing Decision: | Do Not Delist from 303(d) list (being addressed with action other than TMDL)(2024) |
Revision Status | Revised |
Sources: | A Source Unknown |
TMDL Name: | San Diego Bay Sediment Cleanup and Source Control Alternative Restoration Plan |
TMDL Project Code: | 1565 |
TMDL Priority: | Low |
Expected Attainment Date: | 2021 |
Impairment from Pollutant or Pollution: | Pollutant |
Regional Board Conclusion: | No new data. This decision was updated to correct a data entry error that associated the Final Listing Decision with a 4B restoration plan instead of correctly associating this impairment with an Advance Restoration Plan (ARP). Therefore, the previous conclusion remains unchanged, and is as follows: This pollutant is being considered for placement on the section 303(d) list under section 3.1 of the Listing Policy. Under section 3.1 a single line of evidence is necessary to assess listing status. One line of evidence is available in the administrative record to assess this pollutant. Three out of Three samples exceeded the California Toxics Rule Criteria for Copper. 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 section 303(d) list in the Water Quality Limited Segments category. 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. Three of 3 samples exceeded the 3.1 ppb dissolved CTR chronic saltwater criteria and this exceeds the allowable frequency listed in Table 3.1 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 not be removed from the section 303(d) list because applicable water quality standards for the pollutant are being exceeded. |
