City of Salinas
Monitoring and Reporting Program FY24/25
Scope and Budget
DESCRIPTION & PERMIT REQUIREMENT
The City of Salinas is required to perform a Monitoring and Reporting Program (MRP) as indicated in Section K and Attachment D of the NPDES permit. The current MRP was adopted in July 2017 and is in its seventh monitoring year. The City will continue with the current MRP program while an updated MRP is refined and approved by the Water Board in the City’s NPDES permit renewal. Resources under this scope will support the monitoring and reporting program under the current and approved MRP for fiscal year 24/25 (see Table 1 with a schedule of the required pollutant monitoring). Salinas’ monitoring program includes continuous hydrology measurements and water quality stormwater sample collection at three urban drainage outfalls to directly sample and better understand the stormwater volume and pollutant loads generated from the City and discharged to regulated receiving waters. Additionally, stormwater grab samples are collected from the Salinas Pump Station to characterize water quality discharged to the Salinas River. Water quality samples are collected at Gabilan and Natividad upstream of the Salinas MS4 boundary to determine water quality conditions associated with upstream drainages. The attached map illustrates all the designated monitoring sites under the M RP. All data collected will be managed, reviewed, synthesized, and summarized in annual report.
CONTRACT OBJECTIVES :
● Coordinate all stakeholders and consultants to effectively monitor stormwater to meet permit compliance including field sampling teams at urban outfalls, receiving waters, and analytical laboratories.
● Perform and collect stormwater samples at designated urban outfalls for a minimum of three rain events.
● Perform and collect stormwater samples at background receiving water sites and receiving water site at nine visits per year.
● Compile all analytical, hydrology, and water quality data and prepare data for the annual repor t
s
ubmitted to the Regional Board.
BUDGET : $225,000
