<br />fencing where natural barriers are not present. The use of temporary water facilities for the livestock and
<br />guard animals and/or shepherd, as well as other temporary infrastructure (e.g., tanks, corrals, wildlife-safe
<br />fences), may be required with the use of prescribed herbivory as a treatment method. The CalVTP PEIR
<br />determined that prescribed herbivory poses a less than significant impact to water quality because it
<br />involves minimal soil disturbance, is carefully managed, and is subject to protective measures under SPRs.
<br />Because the proposed prescribed herbivory treatments align with those evaluated in the PEIR, potential
<br />impacts to water quality are considered within the scope of the CalVTP and have been fully addressed.
<br />SPRs applicable to this treatment are AD-3, BIO-1, BIO-4, BIO-5, GEO-1, GEO-3, GEO -4, GEO-7, HYD -1, HYD -
<br />2, HYD-3, HYD-4, HYD-6, and HAZ-1. All applicable SPRs listed, except SPRs BIO-4, GEO-3, and HYD-3, are
<br />described in Impact HYD-1 and Impact HYD-2. SPR BIO-4 requires that treatment design avoid loss of
<br />riparian habitat function. SPR GEO-3 requires stabilization of soil disturbed during prescribed herbivory
<br />treatments, and HYD-3 requires various water quality protections for prescribed herbivory treatments.
<br />These SPRs avoid and minimize the risk of substantial water quality degradation by implementation of
<br />prescribed herbivory treatment, making the impact less than significant.
<br />The inclusion of approximately 93 acres of land that is outside the CalVTP treatable landscape in the
<br />proposed treatment area constitutes a change to the geographic extent presented in the PEIR. As
<br />mentioned in Impact HYD-1, a few segments of the project treatment areas that are located outside the
<br />CalVTP treatable landscape are in close proximity to waterbodies entirely or partially outside the treatable
<br />landscape boundary. However, within the boundary of the project area, the surface water conditions are
<br />essentially the same within and outside the treatable landscape; therefore, the water quality impact from
<br />prescribed herbivory treatments is also the same, as described above. This determination is consistent
<br />with the PEIR and would not constitute a substantially more severe significant impact than what was
<br />covered in the PEIR.

<br />Project treatments could include targeted herbicide application to kill, or prevent regrowth of, invasive
<br />plants and noxious weeds. No aerial spraying of herbicides would occur. Herbicides would be applied in
<br />adherence with all USEPA, CalEPA, and California DPR guidelines. Even so, the use of herbicides has the
<br />potential to violate water quality standard regulations or degrade water quality. The CalVTP PEIR found
<br />that the use of herbicides has a less-than-significant impact on water quality because herbicide application
<br />is tightly regulated, applied in accordance with label instructions and legal requirements, and subject to
<br />SPRs that include buffer zones, timing restrictions, and site-specific planning to prevent contamination of
<br />water bodies. Because the proposed herbicide treatments are consistent with those evaluated in the PEIR,
<br />potential impacts to water quality are considered within the scope of the CalVTP and have been fully
<br />addressed through regulatory safeguards and SPRs. The SPRs applicable to this treatment are AD-3, BIO-
<br />1, BIO-4, GEO-1, HAZ-1, HAZ-5, HAZ-6, HAZ-7, HYD-1, HYD-4, and HYD-5. All applicable SPRs listed, except
