Irrigated Lands Regulatory Program Sediment and Erosion Control Plan Training

The Irrigated Lands Regulatory Program (ILRP) was initiated by the Central Valley Regional Water Quality Control Board (RWQCB) in 2003 to prevent agricultural runoff from impairing surface waters, and was later expanded in 2012 to cover discharges to both surface and ground waters.

State and Federal water quality regulations require that growers implement management practices to minimize impairments to surface and ground water quality. In addition to impairment of water quality, sediment and excessive erosion may also cause crop damage and loss, decreased property values, and impacts on sustainability.


Sufficient sediment and erosion control can:

  • Reduce agricultural inputs (water, fertilizer, energy, erosion expenses)
  • Reduce loss of valuable topsoil (contributes to soil fertility and water holding capacity)
  • Improve farm aesthetics
  • Minimize offsite movement of pesticides and fertilizers
  • Improve neighbor relations
  • Limit regulatory concerns such as fines and other enforcement actions and public relation issues

Since 2018, working with the Northern California Water Association, Blankinship & Associates has hosted an online training and certification course for ILRP Sediment and Erosion Control Plan (SECP) self-certification to educate farmers and agricultural landowners in the importance of sediment/erosion control and how to complete and certify their plan.
