In 2017, Regional Water Board staff developed a draft Resolution No. R1-2017-0027 (draft Resolution) and draft Water Quality Trading Framework for the Laguna de Santa Rosa Watershed (draft Framework). A public workshop on the draft Resolution and Framework was held during a regular meeting of the Regional Water Board on June 29, 2017. Audio recordings and other materials related to the workshop (including copies of the draft Resolution and Framework) are available on the Regional Water Board’s meeting agenda webpage here.

The draft Resolution and Framework 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 interested parties. Regional Water Board staff considered all comment letters received, prepared detailed written responses to those comments, and revised the draft Resolution and Framework accordingly. Staff’s responses to substantive comments are available alongside other materials related to the July 11, 2018 hearing on the proposed (i.e., revised) Resolution and Framework on the Regional Water Board’s meeting agenda webpage here.

The approved 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 approved Framework include, but are not limited to the following:
