Important Information for 2018 Crop year

Upcoming Requirements for agriculture within the Coalition boundaries

1.  Farm Evaluation Plan Surveys for Growers in High Vulnerable Areas - No Farm Evaluation plans will need to be turned in for the 2018 crop year. 

2.  Nitrogen Management Plans - Must be completed on the farm site by June 15, 2019.  Those farming in High Vulnerable areas for groundwater leaching of nitrates must have their plans certifiedHigh Vulnerable Areas Map.  (this is a large file and may take time to download)

3. Nitrogen Management Summary Reports for High Vulnerable areas need to be completed and returned to the coalition by April 1, 2019.

Sediment Discharges

Over the past year several violations have been issued by the Regional Water Quality Control Board for growers in delta area of Contra Costa County, Stanislaus County and up in Northern California for excessive sediment discharge of irrigation runoff into waterways. The Regional Board is actively enforcing water quality standards for sediment discharges.

The regional board has issued a letter for all the growers in the area that drains in and around Brentwood and the Discovery Bay.  Click here to see the letter

Here is a UC Extension pamphlet that contains some good information on sediment control.  It discusses pesticides movement in sediment and management practices to prevent sediment from leaving the field.  UC Publication

Here is another publication on sediment pond design published by CURES. Sediment Pond Design

Best Management Practices Links - This page has links to many different sites that provide information on how to address many water quality issues and which practices farmers and ranchers can employ to improve water quality. 

Pesticide Exceedances 

Despite getting Regional Board approval to remove specific pesticides from seven different waterways, samples collected by the Coalition continue to have detections of pesticides.   In 2017 there was three detections of a herbicide above water quality standards (diuron). 

The diruon detections in 2017 occurred in 3 subwatersheds that are already in a management plan for Diuron.   These subwatersheds include Terminous Tract, Temple Creek and Bacon Island.   The Coalition has conducted multiple years of outreach within all the subwatersheds and members within these subwatersheds have documented various management practices such as retention ponds/holding basins, center grass rows, reducing the amount of irrigation runoff and reducing use of the pesticide of concern.

Prohibited Discharge Pesticides

Many within the agricultural community might not realize there are certain pesticides that the Regional Water Quality Control Board have listed as Prohibited Discharge Pesticides.  Some of these pesticides are commonly used without use restrictions.  These products include Carbofuron (Furdan), Malathion, Molinate (Ordram), Methyl parathion (Parathion),and Thiobencarb (Bolero). 

It is important for the agriculture community to prevent any runoff from their property that might contain any of these products.  Anytime the coalitions detects any one of these pesticides it must report to the regional board and take steps to find out the source of the pesticide.  The coalitions will then hold grower meeting to inform growers of proper management practices that need to be implemented to prevent further runoff of these targeted pesticides.
