IMPLEMENTATION PLAN DECEMBER 2018

SEAWALL LONG-TERM MAINTENANCE PROJECT APPENDIX B

Appendix B - Page | 1

INTRODUCTION

This plan specifies measures the Service will implement to mitigate impacts from maintenance and repair of the failing seawall at Mid-way Atoll National Wildlife Refuge (NWR). Multiple federal agen-cies and departments have regulatory jurisdiction over the seawall repairs. This plan provides a single, unified list of all environmental protection measures recommended, required, and approved by all agencies with jurisdiction, as identified in the following table.

SOURCES OF ENVIRONMENTAL MEASURES

The measures listed in this plan have been developed based on the analysis in the EA and on consultations with the jurisdictional agen-cies. Many of the measures are based environmental review and per-mitting for repairs the Service completed in 2014 (FWS and FAA

2013). The 2014 armor rock revetment was typical of the types of repairs that the Service would continue as part of its seawall repair and maintenance program. Measures identified during this process and 2016 - 2018 consultations have been incorporated as fully as possible, but additional measures may need to be added as consul-tations progress.

All project staff should be familiar with the protocols and Best man-agement practices (BMPs) summarized in this Implementation Plan.

Project staff should be notified as additional measures are identified or recommended through consultation.

MEASURES ORGANIZED BY IMPLEMENTATION STEPS

Environmental protection measures have been organized into the seven overall implementation steps identified during the EA prepa-ration for the seawall maintenance program:

1. Design

2. Construction Material Acquisition

3. Shipping

4. Staging

5. Pre-Construction

6. Construction

7. Post-Construction

This plan lists (in table format) the specific environmental measures to be implemented during each step. The Service will use these ta-bles as a checklist for each repair action conducted over the 10-year planning period, as established in the USACE permit.

Appendix B - Page | 2

The tables organize “Measures” for each stage of the project. Each

Measure is identified with an “ID” for future reference. The

“source” field refers to the originating document for each measure by abbreviated form. They are as follows:

PLANNING PROCESS

The Service will conduct repairs as sections of the seawall fails over the ten-year planning period (2016-2026). Because specific loca-tions and extent of repairs needed along the approximately 1-mile long seawall are unknown, the Service established an implementa-tion process that begins when a new failed section of seawall is dis-covered. This process includes four main phases:

1. Assess the situation, where the Service will determine the extent of needed repairs and whether any “significant new circum-stance or information” requires additional environmental re-view, revised permits, or environmental measures.

2. Design, where the Service will determine appropriate designs for repair and notify jurisdictional agencies.

3. Implement, where the Service will fund and issue contracts for construction. This phase contains the construction steps and as-sociated environmental measures contained in this plan.

4. Learn/Improve where the Service will identify any “lesson learned” and revise this Implementation Plan, as needed.

The chart on the following page illustrates the seawall repair imple-mentation process and indicates the steps that include the environ-mental measures identified in this plan. As shown on the chart, the

Service will document each of the four main phases in a NEPA ad-ministrative record it will maintain for its actions related to the sea-wall maintenance and repairs.

DESIGNED ENVIRONMENTAL MEASURES

Avoidance is the first and preferred step to mitigate environmental impacts (per Council of Environmental Quality (CEQ) regulations, 40 CFR 1508.20).

For the seawall maintenance program, the Service will avoid im-pacts on the marine environment by minimizing the project footprint and by conducting all work from land, rather than from barges and vessels. Table 1 provides the specific environmental measures that will be included in each repair design.

CONSTRUCTION MATERIAL AND INVASIVE SPECIES

Due to the critical need to prevent the introduction of invasive spe-cies, rock used to repair the seawall needs to be clean. The Service will specify the requirements listed in Table 2 as part of contracts issued for all seawall repairs.

Protocols prevent reintroduction of invasive species such as Verbesina encelioides, or golden crownbeard

Appendix B - Page | 6

SHIPPING AND INVASIVE SPECIES

Shipping issues relate primarily to invasive species, which is a major concern at Midway Atoll and throughout the larger Pa-pahānaumokuākea Marine National Monument. The Management

Monument permit required for the seawall maintenance program in-cludes several requirements for ensuring ships do not transport in-vasive species into the monument.

Table 3 lists these measures as well as similar measures identified by the USACE of Engineers as part of its Nationwide Permit issued for the 2014 repair.

Rock used for repairs would be barged to the Refuge, likely from existing sources in Hawaii or Alaska.

A silt curtain will be deployed prior to placing fill in the water and during removal of sheet pile to contain turbidity and siltation. The

Service will consult with the design-engineering consultant to de-termine the correct silt curtain for the project location and needs.

The silt curtain would be installed during periods of low wave ac-tion using a Refuge boat located at Sand Island. The silt curtain would be removed during severe weather events to reduce the risk of damage. Refer to measure C-8 and C-27 for additional measures regarding silt curtain management.

POST-CONSTRUCTION

Post-construction follow-up is an important element of the overall environmental measures strategy for the seawall maintenance pro-gram, which includes post-construction reviews to support learning and continual improvement. Through this work, the Service will gain valuable lessons learned and be able to implement changes as needed to ensure that environmental measures goals are met.

Post-construction, provide information on the species, size and the to-tal amount of any corals impacted from the salvage operations. Offset this resource loss, including the loss of EFH bottom habitat. If the overall unavoidable loss is minimal, NMFS would support environ-mental measures offset involving removal of long-standing uncolo-nized debris in areas adjacent to the project fill footprint to future dam-age to the corals and marine resources in the area. Other compensatory environmental measures alternatives may also be appropriate.

Information on the species, size and the total amount of any corals im-pacted from the repairs would be provided to NMFS within 30 days of the completion of repairs. Post-construction marine biological sur-veys would be conducted to determine the actual project-related im-pact and the need for compensatory Environmental Measures. Lost ecological function associated with any project impact must be miti-gated through mutually agreed conditions.
