Groundwater Monitoring - Ag Order

The Central Coast Water Board approved a new Agricultural Order on March 8, 2017. This is a three-year Agricultural Order which must be replaced by March 7, 2020. The new Agricultural Order is the third Agricultural Order adopted in the central coast region, so is referred to as Ag Order 3.0.

Ag Order 3.0 requires groundwater monitoring in 2017 and also expands the Total Nitrogen Applied reporting requirement (Tier 2 & 3, for operators growing high risk crops - not grapes). Please review the highlights of these two requirements below.

GROUNDWATER MONITORING

Groundwater well monitoring is required in 2017. Growers must sample:

  1. primary irrigation well located on each ranch, and
  2. all domestic wells located on the assessor parcel numbers where the ranch is located.

Two rounds of sampling from all required wells were due in 2017.

The first sample from each required well must be drawn from March-June 2017 and the second sample from September-December 2017. Groundwater samples must be collected by a qualified third party, such as a consultant, technician or person conducting cooperative monitoring on behalf of the grower.

As in Ag Order 2.0, laboratory analysis must be conducted by a State certified laboratory that can coordinate with the grower to submit the sampling results electronically using the Water Board’s GeoTracker electronic deliverable format (known as EDF).

If these samples were not completed and reported, growers would have recieved Notice of Violation (NOV) letters.
