| Regional Board Conclusion: | This pollutant is being considered for placement on the CWA section 303(d) List under section 2.2 and 4.5 of the Listing Policy. Under section 4.5 a single line of evidence are necessary to assess listing status. 4 lines of evidence are available in the administrative record to assess this pollutant. 0 of 8 sample exceeded the guideline for chlordane in fish tissue. 8 of 8 sample exceeded the guideline for chlordane in fish tissue. 0 of 8 sample exceeded the guideline for chlordane in fish tissue. 0 of 0 sample exceeded the guideline for chlordane in fish tissue. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against removing this water segment-pollutant combination from the CWA section 303(d) List. There is sufficient justification to place it in the Being Addressed portion of the CWA 303(d) List because a TMDL has been completed and approved by RWQCB and USEPA, and is expected to result in attainment of the standard. 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. 8 of 8 samples exceeded the guideline and this exceeds the allowable frequency listed in Table 4.1 of the Listing Policy. 4. The Los Angeles Area Lakes TMDL for Nitrogen, Phosphorus, Mercury, Trash, Organochlorine Pesticides and PCBs was approved by USEPA on 3/26/2012 5. Pursuant to SECTION 4.11 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. |

| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Conclusion: | This pollutant is being considered for removal from the CWA section 303(d) List under section 4.5 and 4.11 of the Listing Policy. Under section 4.5 a single line of evidence is necessary to assess listing status. Under section 4.11 when all other delisting factors do not result in the delisting of a water segment but information indicates attainment of standards, a water segment shall be evaluated to determine whether the weight of evidence demonstrates that water quality standard is attained. If the weight of evidence indicates attainment, the water segment shall be removed from the CWA section 303(d) List. Twelve lines of evidence are available in the administrative record to assess the pollutant. LOE 719 is replaced with LOE 307642. LOE 307642 is a reassessment of the same data following the statewide mercury objectives adopted in 2017. LOE 94991 is replaced with LOE 307591. LOE 307591 is a reassessment of the same data following the statewide mercury objectives adopted in 2017. COMM beneficial use: Fish used in the COMM assessment are limited to lengths that are within Calif. Dept. of Fish and Wildlife legal size limits applicable to this waterbody. LOE 307642: 2 of 2 samples exceed the mercury objective and consist of 12 trophic level 4 fish (CDFW legal size limit). LOE 307591: 1 of 1 samples exceed the mercury objective and consist of 11 trophic level 4 fish (CDFW legal size limit). LOE 244807: 1 of 1 samples exceed the mercury objective and consist of 5 trophic level 4 fish (CDFW legal size limit). LOE 244829: 0 of 1 samples exceed the mercury objective and consist of 10 trophic level 4 fish (CDFW legal size limit). LOE 244949: 1 of 1 samples exceed the mercury objective and consist of 10 trophic level 4 fish (CDFW legal size limit). WILD beneficial use: LOE 244810: 0 of 1 samples exceed the mercury objective and consist of 29 trophic level 3 and 4 fish. LOE 307661: 2 of 2 samples exceed the mercury objective and consist of 12 trophic level 4 fish (CDFW legal size limit). LOE 307691: 1 of 1 samples exceed the mercury objective and consist of 11 trophic level 4 fish (CDFW legal size limit). LOE 244861: 1 of 1 samples exceed the mercury objective and consist of 5 trophic level 4 fish (CDFW legal size limit). LOE 244837: 0 of 1 samples exceed the mercury objective and consist of 10 trophic level 4 fish (CDFW legal size limit). LOE 244980: 1 of 1 samples exceed the mercury objective and consist of 10 trophic level 4 fish (CDFW legal size limit). Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against removing 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 data used satisfies the data quantity requirements of section 6.1.5 of the Policy. 3. CDFW legal size limit fish fillet tissue samples were compared with the sport fish objective and 5 of 6 samples exceed for WILD beneficial use and 5 of 6 samples exceed for the COMM beneficial use. The samples consist of trophic level 4 fish and are from a minimum of 2 annual averages and this exceeds the allowable frequency listed in Table 4.1 of the Listing Policy. 4. Pursuant to section 4.11 of the Listing Policy, no additional data and information are available indicating that standards are met. |
| Regional Board Decision Recommendation: | Decision written by SWRCB staff. |
| State Board Review of Regional Board Conclusion and Recommendation: | |
| State Board Decision Recommendation: | After review of the available data and information, SWRCB 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. |

| Final Listing Decision: | Do Not Delist from 303(d) list (being addressed with USEPA approved TMDL) |
| Last Listing Cycle's Final Listing Decision: | Do Not Delist from 303(d) list (TMDL required list)(2018) |
| Revision Status | Revised |
| Sources: | A Source Unknown |
| TMDL Name: | Echo Lake, PeckRd Lake DDT/PCBs/Chlordane (19) |
| TMDL Project Code: | 367 |
| Date TMDL Approved by USEPA: | 03/26/2012 |
| 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 2.2 and 4.5 of the Listing Policy. Under section 4.5 a single line of evidence are necessary to assess listing status. 4 lines of evidence are available in the administrative record to assess this pollutant. 0 of 2 sample exceeded the guideline for PCBs in fish tissue. 2 of 2 samples exceeded the guideline for PCBs in fish tissue. 0 of 2 sample exceeded the guideline for PCBs in fish tissue. 0 of 0 sample exceeded the guideline for PCBs in fish tissue. Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification against removing this water segment-pollutant combination from the CWA section 303(d) List. There is sufficient justification to place it in the Being Addressed portion of the CWA 303(d) List because a TMDL has been completed and approved by RWQCB and USEPA, and is expected to result in attainment of the standard. 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. 2 of 2 samples exceeded the guideline for PCBs in fish tissue nd this exceeds the allowable frequency listed in Table 4.1 of the Listing Policy. 4. The Los Angeles Area Lakes TMDL for Nitrogen, Phosphorus, Mercury, Trash, Organochlorine Pesticides and PCBs was approved by USEPA on 3/26/2012 5. Pursuant to SECTION 4.11 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. |

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. 0 of 8, 0 of 8 and 0 of 8 sample exceeded the GUIDELINE and this sample size is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. A minimum of 16 samples is needed to determine if a beneficial use is fully supported using table 3.1. 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 placed on the section 303(d) list. The readily available data and information is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. |

| Revision Status | Revised |
| 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 3.5 of the Listing Policy. Under section 3.5 a single line of evidence are necessary to assess listing status. 3 lines of evidence are available in the administrative record to assess this pollutant. 0 of 8 sample exceeded the GUIDELINE. 0 of 7 sample exceeded the GUIDELINE. 0 of 8 sample exceeded the GUIDELINE. Based on the readily available data and information, the weight of evidence indicates that there is insufficient justification for 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. 0 of 8, 0 of 0 and8 of 8 sample exceeded the GUIDELINE and this sample size is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. A minimum of 16 samples is needed to determine if a beneficial use is fully supported using table 3.1. 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 placed on the section 303(d) list. The readily available data and information is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. |

| Revision Status | Revised |
| 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 3.5 of the Listing Policy. Under section 3.5 a single line of evidence are necessary to assess listing status.
1 line of evidence is available in the administrative record to assess this pollutant. 0 of 0 sample exceeded the GUIDELINE. Based on the readily available data and information, the weight of evidence indicates that there is insufficient justification for 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. 0 of 0 sample exceeded the GUIDELINE and this sample size is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. A minimum of 16 samples is needed to determine if a beneficial use is fully supported using table 3.1. 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 placed on the section 303(d) list. The readily available data and information is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. |
| 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. |

| Regional Board Decision Recommendation: | After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list. The readily available data and information is insufficient to determine, with the power and confidence of the Listing Policy, the applicable beneficial use support rating. |
| State Board Review of Regional Board Conclusion and Recommendation: | |
| State Board Decision Recommendation: | After review of the available data and information, SWRCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list because it cannot be determined if applicable water quality standards are not being exceeded. |

| Data Used to Assess Water Quality: | Water Board staff assessed San Gabriel River Regional Monitoring Program data for Puddingstone Reservoir to determine beneficial use support and the results are as follows 1 of the 1 samples exceeded the water quality threshold for Toxaphene. Data were collected for 8 fish species (1 composite(s) of Common Carp each composed of 4 fish per composite, 1 composite(s) of Redear Sunfish each composed of 14 fish per composite, 1 composite(s) of Redear Sunfish each composed of 5 fish per composite, 1 composite(s) of Redear Sunfish each composed of 3 fish per composite, 1 composite(s) of Largemouth Bass each composed of 16 fish per composite, 1 composite(s) of Largemouth Bass each composed of 5 fish per composite, 1 composite(s) of Black Crappie each composed of 15 fish per composite, 1 composite(s) of Black Crappie each composed of 5 fish per composite). Of these species, 1 species (Largemouth Bass) exceeded the evaluation guideline. Although a total of 8 samples were collected 7 of these samples were not included in the assessment because the laboratory data reporting limit(s) was above the objective and therefore the results could not be quantified with the level of certainty required by the Listing Policy Section 6.1.5.5. | ||||

| Evaluation Guideline: | The modified OEHHA Fish Contaminant Goal for toxaphene in fish tissue is 4.3 ppb. This screening level assumes an average body weight of 70 kg and a consumption rate of 32 g/day for a 30 year exposure over a 70-year lifetime. This constituent is a carcinogen therefore the risk level is set to one in a million. A cooking reduction factor of 1 is applied for skin-off fillets. (Klasing, S., and R. Brodberg, 2008) | ||||
