Requirements for CM Plans
(1)
CM Plan Content. CM Plan detail must be commensurate with the size and complexity of the proposed mitigation. A CM Plan is not required for proposed CM by means of using credits from an approved bank, advance mitigation site, in-lieu fee mitigation or payment in-lieu mitigation. A CM plan for permittee responsible CM must include the sections listed below.(a)
CM plan overview, including:(A)
CM ecological goals and objectives;(B)
The CM concept in general terms including a description of how the plan, when implemented, will replace the functions and values of the impacted waters of this state;(C)

Plans for CM by means of restoration must include documentation sufficient to demonstrate that the site was formerly, but is not currently, a water of this state.(G)
Plans that involve enhancement must include identification of the cause(s) of degradation and how the plan will reverse it and sustain the reversal.(e)
A functions and values replacement assessment. The applicant must demonstrate whether the functions and values that will be lost by the project will be replaced by the functions and values predicted at the CM site. Predicted functions and values should be based on the reasonably envisioned future state of the CM site based on the CM design. A summary of the assessments must be placed in the body of the CM plan, and supporting data sheets or assessment model outputs must be placed in an appendix of the CM Plan. A replacement assessment is not required when CM is proposed to be fulfilled by purchase of legacy credits, in-lieu fee mitigation credits not associated with a Department-approved project, or payment in-lieu mitigation.(f)
CM drawings and specifications, including:(A)
Proposed construction schedule;(B)
Scaled site plan(s) showing CM project boundaries, existing and proposed boundaries of waters of this state, restoration, creation and enhancement areas, buffers, existing and proposed contours, cross-section locations, construction access location and staging areas;(C)
Scaled cross sections showing existing and proposed contours and proposed water depths;(D)
Plant list for each Cowardin and HGM wetland and tidal waters class at the CWM site and buffers at all CM sites (include scientific names and wetland indicator status);(E)
Schematic of any proposed water control structures;(F)
Identification of any water rights necessary to sustain the intended design and functions. When water rights are required, the applicant must provide documentation that the water right has been secured prior to issuance.(G)
For CM sites involving tidal waters, plan views and cross-sections must show relevant tidal elevations relative to mean lower low water (MLLW) using the nearest local tidal datum. The elevation of MLLW must be referenced to the North American Vertical Datum 1988 (NAVD88).(g)
Proposed CM performance standards. The applicant may propose to use applicable pre-defined performance standards as approved by the Department, or may provide CM site-specific performance standards that:(A)
Address the proposed ecological goals and objectives for the CM;(B)
Are objective and measurable; and(C)
Provide a timeline for achievement of each performance standard.(h)
A description of the proposed financial security instrument. The Department will determine the amount of security required. A final financial security instrument will be required prior to permit issuance unless otherwise approved by the Department.(i)
A monitoring plan including specific methods, timing, monitoring plot locations, and photo-documentation locations.(j)
A long-term maintenance plan describing:(A)
How the applicant anticipates providing for maintenance of the CM site beyond the monitoring period to ensure its sustainability (e.g., maintenance of any water control structures, weed management, prescribed burning, and vandalism repair);(B)
Expected long-term ownership of the CM site and the anticipated responsible party or parties for long-term maintenance; and(C)
How the maintenance activities are anticipated to be funded.(k)
