Regional Board 2 - San Francisco Bay Region

Water Body Name:	Fitzgerald Marine Reserve at Moss Beach
Water Body ID:	CAC2022100020190104026259
Water Body Type:	Coastal & Bay Shoreline


DECISION ID	150931	Region 2
Fitzgerald Marine Reserve at Moss Beach

Pollutant:	Ammonia
Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	New Decision
Revision Status	Revised
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	Insufficient information is available to determine beneficial use support for this waterbody-pollutant combination with the statistical power and confidence required by the Listing Policy. Beneficial use support will be reassessed in a future cycle, if more data are available

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.

Fitzgerald Marine Reserve at Moss Beach

Pollutant:	Silver
Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	New Decision
Revision Status	Revised
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	Insufficient information is available to determine beneficial use support for this waterbody-pollutant combination with the statistical power and confidence required by the Listing Policy. Beneficial use support will be reassessed in a future cycle, if more data are available.

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.

DECISION ID	149885	Region 2
Fitzgerald Marine Reserve at Moss Beach

Pollutant:	Indicator Bacteria
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:	A Source Unknown
Expected Attainment Date:	2037
Implementation Action Other than TMDL:	The San Francisco Bay Regional Water Quality Control Board, at its May 11, 2016 hearing, adopted a Resolution to support the Water Quality Improvement Plan for bacteria in San Vicente Creek and Fitzgerald Marine Reserve. The Plan describes bacteria sources in the watershed, proposes high-priority implementation actions to reduce loading from horse waste, dog waste, human waste from onsite wastewater treatment systems, and stormwater runoff and identifies the regulatory mechanisms for the actions. The Plan also includes water quality monitoring to evaluate effectiveness of the corrective actions and assess attainment of standards.
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	This pollutant is being considered for placement on the CWA section 303(d) List under sections 2.2 and 3.3 of the Listing Policy. Under section 3.3 of the Policy, a minimum of one line of evidence is needed to assess listing status. Multiple lines of evidence are available in the administrative record to assess this pollutant. One hundred nineteen of two hundred eighty-six samples exceed the the enterococcus geometric mean objective. 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 on the 303(d) list being addressed by action other than TMDL. The San Francisco Bay Regional Water Quality Control Board, at its May 11, 2016 hearing, adopted a Resolution to support the Water Quality Improvement Plan for bacteria in San Vicente Creek and Fitzgerald Reserve. Therefore, there is justification for moving this impairment to the category of listings being addressed by an action other than a TMDL. 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. One hundred nineteen of two hundred eighty-six samples exceed the the enterococcus geometric mean objective. and this exceeds the allowable frequency listed in Table 3.2 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:	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.
