Regulatory Relief: SIP Certified will report TNA for Ag Order 4.0 members

posted: September 14, 2023

SIP Certified has partnered with Preservation Inc. to save you time by reporting Total Nitrogen Applied (TNA) for Regional Water Quality Control Board Region 3 Ag Order 4.0.

Your responses in Chapter 14 will be used to calculate TNA. With the help of Preservation Inc., we will submit your data to the Water Board on your behalf.

Get Started

1. Add your AW, AGL(s), and APN(s) to your Ranch(es) in the SIP Certified database (tutorial) by Dec 5.

  • 100% of the vineyard on the AGL must be SIP Certified.
    • If you have a partially SIP Certified ALG and want to split it into two, contact
  • All acres in a single AGL must be winegrapes.

2. Complete Chapter 14 by Dec 5.

  • Please note, it is important that your answers are on time and complete in order to remain in this regulatory relief program.

3. Review, sign, and return the Agreement.


Q: Does this apply to me?

A: This only applies to vineyards in the Central Coast Region (Region 3 Water Quality Control Board).

Q: What region am I in?

A: Check the Water Board map to see what region your vineyard is in.

Q: Is this required?

A: You are not required to report through SIP; however, all Central Coast farms are now required to report TNA to the Water Board. This regulatory relief offered by SIP Certified will save you time and hassle of reporting to the Water Board yourself. We are offering this regulatory relief as a benefit to you for being SIP Certified!

When you add your AW, AGL, and APNs to your Ranch in the database, your answers for Chapter 14 Year-End Water and Nitrogen Use Reports will be used to calculate TNA. Your data will be sent to Preservation Inc., who will report to the Water Board on your behalf.

Q: In the SIP Certified database, can more than one Ranch have the same AGL?

A: Yes, if more than one of your Ranches in the database has the same AGL, you can put the same AGL into multiple Ranches.

Q: My Ranch in the database has more than one AGL, but the database only allows 1 AGL per Ranch. What should I do?

A: Your database Ranch will need to be split up into as many Ranches as you have AGLs.
For example, if your Ranch named “El Camino” covers three AGLs, you will need three El Camino Ranches: El Camino 1, El Camino 2, and El Camino 3.
