| TMDL Name: | Ballona Creek Trash |
| TMDL Project Code: | 608 |
| Date TMDL Approved by USEPA: | 01/01/2019 |
| Impairment from Pollutant or Pollution: | Pollutant |
| Regional Board Conclusion: | Region 4 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle.
This pollutant is being considered for listing under section 2.2 of the Listing Policy. Under this section of the Policy, a minimum of one line of evidence is needed to assess listing status. The Ballona Creek Trash TMDL was approved by the RWQCB in 2001 and subsequently approved by USEPA. 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. |
