Water Body Type:	River & Stream


DECISION ID	18526	Region 3
Salinas Reclamation Canal

Pollutant:	Nitrogen, Nitrate
Final Listing Decision:	Delist from 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Delist from 303(d) list (TMDL required list)(2010)
Revision Status	Original
Reason for Delisting:	Flaws in original listing
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	Region 3 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle.

Regional Board Decision Recommendation:	No new data were assessed for 2012. The decision has not changed.

State Board Staff 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 be removed from the section 303(d) list because the water body was erroneously designated to support the MUN beneficial use, the water quality objective therefore does not apply and applicable water quality standards for the pollutant are not exceeded.

Data Used to Assess Water Quality:

The Salinas Reclamation Canal is currently listed on the 303(d) list as impaired for nitrate. Regional Board staff proposed delisting this water body for nitrate. The Salinas Reclamation Canal is located in the lower Salinas River watershed. It was placed on the 303(d) list in 2002. The Salinas Reclamation Canal was listed as impaired for nitrate because data indicated that the nitrate water quality objective protecting the MUN beneficial use was being exceeded. The nitrate water quality objective protecting the MUN beneficial use is 10 mg/L-N. The Salinas Reclamation Canal was erroneously listed as impaired for nitrate because it was assumed that this water body is designated to support the MUN beneficial use. However, the Salinas Reclamation Canal is not designated to support the MUN beneficial use, and the nitrate water quality objective therefore does not apply.CCAMP and CCoWS datasets.

SWAMP Data:

Non-SWAMP

Water Quality Objective/Criterion:

From the delisting report: "Applicable water quality objectives: the 303(d) listing is for nitrate, which is protected by the nitrate water quality objective protecting the MUN beneficial use. Since the water body is not designated to support the MUN beneficial use, the nitrate water quality objective does not apply."

QAPP Information:

There are two sources of data: 1) Data compiled by Central Coast Watershed Studies (CCoWS), and 2) CCAMP of the Regional Water Quality Control Board Central Coast Region.
The data compilation by CCoWS does not have a formal QAQP. This portion of the data set represents 62% of the entire dataset.
The CCAMP QAQP is shown in the document titled: QAQP for Salinas Reclamation Canal Delist. This portion of the dataset represents 38% of the entire dataset.

Data Used to Assess Water Quality:

Central Coast Regional Board Staff assessed Don Westin Toxicity study (R3_Weston) data for Salinas Reclamation Canal to determine beneficial use support and results are as follows: 5 of 5 samples exceed the criterion for Toxicity, Hyalella azteca Survival (%) 10 days. Toxicity is defined by SWAMP (2004) as follows: Significant toxicity in the survival endpoint when compared to the negative control based on a statistical test with alpha of less than 5%, and less than the evaluation threshold (both criteria are met).

Data Reference:

Final Data File used for assessment: Don Weston Salinas Toxicity Data

SWAMP Data:

Non-SWAMP

Water Quality Objective/Criterion:

All waters shall be maintained free of toxic substances in concentrations which are toxic to, or which produce detrimental physiological responses in, human, plant, animal, or aquatic life. Compliance with this objective will be determined by use of indicator organisms, analyses of species diversity, population density, growth anomalies, toxicity bioassays of appropriate duration, or other appropriate methods as specified by the Regional Board (Water Quality Control Plan, Central Coast Basin, Chapter III, Section II.A.2 Objectives for all Inland Surface Waters, Enclosed Bays and Estuaries).

Objective/Criterion Reference:

Water Quality Control Plan (Basin Plan) - Central Coast Region (Region 3)

Evaluation Guideline:
