ILRP - Ag Order 4.0

In November 2018, the Central Coast Regional Water Quality Control Board released five Options Tables describing their vision for the next iteration of the Irrigated Lands Regulatory Program for Central Coast Agriculture (known widely as Ag Order 4.0).  The Options Tables focused on numeric standards and prohibitions that would largely be unattainabile throughout the cycle of Ag Order 4.0 and make compliance montoring and reporting vastly more expensive and difficult for all farms.

In February 2020, Regional Water Board staff released their proposed program for Irrigated Lands in the Central Coast Region (the draft Ag Order 4.0).  There was a public comment period, extended twice, to accommodate timing of COVID-19 shelter-in-place orders.

Working throughout the 2019 & 2020 years, six Ag associations came together to develop an agricutlural proposal to the staff's harsh regulatory program proposal.  These associations are: Monterey County Farm Bureau, Grower-Shipper Assocation of Central California, California Farm Bureau Federation, Grower-Shipper Association of San Luis Obispo & Santa Barbra Counties, Western Growers, and Western Plant Health Association (known collectively as the Ag Partners).

Monterey County Farm Bureau and Grower-Shipper Association of Central Califonria formed a Technical Advisory Committee in 2018 to specifically address the regulatory challenges of developing a workable, implementable Ag Order.  Additionally, imput was received from other agricultural organizations that are not signatories to the Ag Partners submission.

The Ag Partners proposal was submitted to the Regional Water Board during the comment period that ended in June 2020.  The proposal was then presented, via ZOOM, to the Regional Water Board members and staff at a public workshop held on September 10th and 11th.  Further hearings are scheduled for September 23rd and 24th.

Ag Order 4.0 is expected to be adopted in January, 2021.

Monterey County Farm Bureau supports the use of General Discharge Requirements (WDR) for this next iteration of the Ag Order (rather than another conditional waiver that is limited to five years).  This allows for more regualtory flexibility and certainty, as noted in the narrative document.

MCFB, along with our Ag  organization partners, will continue to monitor Ag Order 4.0 as it is fully considered during 2020 Regional Water Board meetings.  MCFB has committed significant funding to the Ag Partners submission including expert reports on agronomy, economics, and legal issues.
