Agricultural Order Requirements and Documents

Taken directly from Central Coast Regional Water Board website: Irrigated Land Regulatory Program Homepage

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. Please review the highlights of these two requirements below.

We will provide additional information soon, such as an updated compliance calendar, information about workshop opportunities, and more.

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 are 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).

For more information about groundwater monitoring requirements, please see any of the Monitoring and Reporting Program documents below, Part 2 A and B. Groundwater monitoring guidance documents, including a list of qualified laboratories, will be available soon on this webpage in the Grower Workshops and Resources section.

The Total Nitrogen Applied reporting requirement is now expanded to include all ranches that grow any crop with a high potential of loading nitrogen to groundwater. These “high risk” crops include the following: beet, broccoli, cabbage, cauliflower, celery, Chinese cabbage (Napa), collard, endive, kale, leek, lettuce (leaf and head), mustard, onion (dry and green), spinach, strawberry, pepper (fruiting), and parsley. If any of these crops are grown on your ranch, then a Total Nitrogen Applied report is required for all crops grown on the ranch.

The first Total Nitrogen Applied report for Ag Order 3.0 is due on March 1, 2018. You will need to report the Total Nitrogen Applied to all crops harvested on the ranch during the 2017 calendar year. Make sure to track all nitrogen applied from fertilizers, compost, and other materials to each crop; track the total volume of irrigation water applied to the ranch; sample your irrigation water for nitrate; and sample your soil for nitrogen, so you can accurately report on March 1, 2018.

For more information on Total Nitrogen Applied reporting, please see the Monitoring and Reporting Program for Tier 2 or Tier 3 ranches below, Part 2C. Total Nitrogen Applied reporting instructions and forms are available on this webpage in the Grower Workshops and Resources section.
