Placeholder area

Some approaches to nutrient TMDL development can be found in the following reports:

  • The Chorro Creek Nutrient TMDL report set a sodium concentration limit of 50 mg/L and total dissolved solids concentration of 500 mg/L in order to help achieve the water quality objective for nutrient concentations
  • The Pajaro River and Llagas Creek report sets the maximum concentration for nitrate within the water body at 10mg/L in order to protect beneficial uses. The report does not include seasonality because it the TMDL is equal to the water quality objectives of the region.
  • The San Diego Creek and Newport Bay Report set the nitrate TMDL according to different seasons. They allow 13 lbs./day of inorganic nitrogen for reach 2,224 lbs./day from October 1 to March 31 total nitrogen and 175 lbs./day from April 1 to September 30.

source analysis

Examples of approaches to monitoring found in similar regional TMDL reports

  • Pajaro/Llagas Creek Nutrient TMDL: Follow-up monitoring data on Nitrate will be provided by the Monitoring and Reporting Program in the Ag waiver. Water Board staff will review data every three years. Additional monitoring will assess causes of excessive algae and low dissolved oxygen conditions that lead to impairment of water bodies.
  • San Luis Obispo Creek Nutrient TMDL :The City of San Luis Obispo required to monitor effluent from the Water Reclamation Facility (WRF)in accordance with the NPDES permit. Cropland monitoring is consistent with the Ag Waiver. Regional Water Board Staff will review the results every three years.
  • Santa Clara River Nutrient TMDL: dry and wet weather discharges will be monitored from agricultural, urban and open space sources to determine if best management practices are effective at reducing nutrient loading, Publicly Owned Treatment Works (POTW) monitoring is outlined in Plans submitted by permitees in Los Angeles and Ventura Counties.
