Current through Register 2024 Notice Reg. No. 38, September 20, 2024

The following watershed issues shall be addressed in an SYP:

(a) Assessment Area. The minimum assessment area shall be no less than a Planning Watershed. The assessment area may include multiple watersheds within a Management Unit, and areas outside the ownership may be included.

(b) Impacts Analysis and Mitigation. The Assessment shall include an analysis of potentially significant adverse impacts, including Cumulative Impacts, of the planned operations and other Projects, on water quality, fisheries and aquatic wildlife.

(c) The SYP shall contain a description of the individual Planning Watersheds in sufficient detail to allow a review of the analysis of impacts.

(1) For all Planning Watersheds in the ownership within a forest District descriptions shall include as appropriate:
(A) Estimate of the stand structure type acreage and percent composition of the watershed by decade.

(B) General maps and descriptions of Unstable Areas and Unstable Soils known to the Plan submitter to be actively or potentially discharging sediment, as well as those mapped by public agencies.

(2) For the initial ten year period, for all Planning Watersheds in which harvesting will take place, descriptions shall include as appropriate:
(A) Map of existing roads and approximate location and miles of proposed new, Reconstructed and Abandoned Roads.

(B) Estimate of the SYP submitter's ownership acres of forest types to be harvested by silvicultural method and Yarding method, and the location of submitter's approved and submitted THPs and presently projected future Timber Operations.

(C) A general description of areas known to be sensitive to ground disturbance and present sources of erosion.

(d) The SYP shall also discuss and include Feasible measures planned to mitigate or avoid significant adverse impacts. Where significant impacts are identified and Feasible mitigation is not available, a THP relying upon a SYP shall address these remaining impacts. The SYP submitter shall utilize any one or a combination of methods to assess adverse watershed impacts including but not limited to:

(1) Board Technical Rule Addendum #2 (14 CCR § 912.9, 932.9, 952.9).

(2) The use of a Cumulative Watershed Effects Analysis, including the Equivalent Roaded Area (ERA) method, for screening Planning Watersheds to determine whether watershed-specific thresholds of concern have been exceeded when appropriate.

(3) Other methods proposed in the SYP and approved by the Director.

(e) Multiple Ownerships. In areas with multiple ownerships, landowners may cooperate to establish a management unit and develop a watershed assessment.
