date see monitoring report in renewal request letter. Thus, the subset of Level B harassment take remaining from that
authorized under the 2020 IHA will be sufficient to cover the remaining 2021
restoration work at the Minhoto-Hester Restoration Area.
Detailed Description of the Activity As discussed earlier, this is a Renewal to complete the subset of the activity not completed under the initial IHA 85 FR
14640; March 13, 2020. Due to construction delays attributed to severe weather in the winter of 2020 which limited the ability for heavy equipment to access and mobilize onsite in addition to smaller construction crew sizes than anticipated, only 118 days of work occurred between August 2020
and April 2021 of the 180 days anticipated and authorized for this project. The completed work to date includes the majority of earthwork at Minhoto-Hester Restoration Area in subareas M4ab, and M5. As of the submission of their Renewal request, 62
days of work remains at the MinhotoHester Restoration Area which will occur between the time the Renewal is issued and September 2021. The applicant requests authorization for the work remaining as of June 1, 2021
which includes placement of additional

fill in subareas M5 and M6 see Table 1 to raise the subsided marsh plain;
excavation of tidal channels in all subareas; and rerouting tidal flow from the existing tidal channel adjacent to Yampah Marsh to the new tidal channel that bisects subareas M4b and M5. All of the remaining work is consistent with work described in the initial IHA. Table 1 same as Table 1 from application and initial proposed presents the acreages and extents of proposed fill within each marsh subarea, as well as the volume of fill required for each marsh subarea to be restored. The upland borrow area, onsite, would be used as the fill source.
The project would rely primarily on natural vegetation recruitment in the restored marsh areas.
This Renewal request is identical to that of the 2020 IHA, in that it is comprised of a subset of the work that was covered in the initial IHA. The location, timing, and nature of the activities, including the types of equipment planned for use, are identical

to those described in the previous notices. The proposed Renewal would be effective until May 31, 2022 and does not authorize activities related to restoration work in the Seal Bend Restoration Area as a subsequent IHA
application will be submitted by CDFW
for such activities at a later date.
The mitigation and monitoring will be identical to that of the 2020 IHA. A
detailed description of the restoration activities for which take is proposed may be found in the notices of the proposed 84 FR 72308; December 31, 2019 and the final IHAs 85 FR 14640;
