Critical aquifer recharge area reports shall include the following site- and proposal-related information unless the administrator determines that any portion of the requirements is unnecessary given the scope and/or scale of the proposed development:
(1)
A site plan that shows:
(a)
Existing physical features of the site including buildings, fences, and other structures, roads, parking lots, utilities, water bodies, etc.
(b)
A detailed depiction of the proposed development including features such as utility location (well, septic, drainfield, etc.); parking and access location; the limits of grading and vegetation removal; and the location of any proposed building(s).
(c)
An identification of critical areas and buffers within 300 feet of the site and an estimate of the existing approximate acreages for each. Assessment of off-site critical areas shall be based on available information and shall not require access to off-site properties.
(2)
The following additional information:
(a)
Available information regarding geologic and hydrogeologic characteristics of the site, including the surface location of all critical aquifer recharge areas on-site and immediately adjacent to the site, the permeability of the unsaturated zone, and the presence of any confining layers.
(b)
Ground water depth, flow direction and gradient based on available information.
(c)
Currently available data on wells and springs within 1,320 feet of the project area.
(d)
Existing and available historic water quality data for the area to be affected by the proposed activity.
(e)
The effects of the proposed project on ground water quality and quantity, including:
(i)
Potential effects to stream flow, wetlands and/or other resources, and ecosystem processes.
(ii)
A predictive evaluation of ground water withdrawal effects on nearby wells and surface water features.
(iii)
A predictive evaluation of the transport of contaminants to ground waters in the event of a spill based on existing confining layers, the availability of centralized wastewater treatment, the nature of the chemicals and/or processes utilized in the proposed activity, and other features.
(f)
Proposed best management practices to preserve ground water quality and quantity, including how the proposal meets any local, state or federal guidance or standards.
(g)
A spill plan that identifies equipment and/or structures that could fail and result in an impact to ground water. Spill plans should include emergency response provisions as well as items that address regular inspection, and the repair and/or replacement of structures and equipment that could fail.
