Water Quality Trading Framework for the Laguna de Santa Rosa Watershed

In 2017, Regional Water Board staff developed a draft Water Quality Trading Framework for the Laguna de Santa Rosa Watershed (draft Framework), and a draft Regional Water Board Resolution No. R1-2017-0027 (draft Resolution), which approves the draft Framework. The draft Framework is intended to replace the existing Santa Rosa Nutrient Offset Program and to be available to both the City of Santa Rosa and the Town of Windsor as an approved method for complying with “no net loading” effluent limitations for total phosphorus in each of their NPDES permits. The draft Framework and Resolution are available at the following links:

A public workshop on the draft Framework and Resolution was held during a regular meeting of the Regional Water Board on June 29, 2017. Audio recordings and supporting documents from the workshop are available here.

The draft Framework and Resolution were open for public review and written comment between June 14, 2017 and July 21, 2017. A total of 11 unique comment letters were received from the following parties. Copies of each comment letter are linked to each party’s name:

Regional Water Board staff have considered all comment letters received, and are currently developing written responses to substantive comments, as well as revisions to the draft Framework and Resolution based on those comments. A public hearing has been scheduled during a regular meeting of the Regional Water Board on July 11, 2018. At the hearing, the Regional Water Board will consider whether to affirm, reject, or modify the proposed (i.e., revised) Water Quality Trading Framework for the Laguna de Santa Rosa (proposed Framework) and proposed Resolution No. R1-2018-0025 (proposed Resolution). Staff’s responses to substantive comments and the proposed Framework and Resolution will be made publicly available at least ten (10) days prior to the hearing. The public hearing notice is available at the following link:

The proposed Framework is a revised, expanded, and improved version of the Santa Rosa Nutrient Offset Program. Its provisions are based on USEPA policy, guidance from national experts, local stakeholder recommendations, and on public comments received on the draft Framework. References used by staff to develop the proposed Framework include, but are not limited to the following:
