For wetland Classes I, II, III and IV, the proposed activity must be compatible with the public health and welfare, be the only practible alternative that could accomplish the applicant's objectives and have no practicable alternative on a site that is not a freshwater wetland or adjacent area.
For wetland Classes I, II, and III, the proposed activity must minimize degradation to, or loss of, any part of the wetland or is adjacent area and must minimize any adverse impacts on the functions and benefits that the wetland provides.
For wetland Class IV, the proposed activity must make a reasonable effort to minimize degradation to, or loss of, any part of the wetland or its adjacent area.
Class I wetlands | Class II wetlands | Class III wetlands | Class IV Wetlands |
Class I wetlands provide the most critical of the State's wetland benefits, reduction of which is acceptable only in the most unusual circumstances. A permit shall be issued only if it is determined that the proposed activity satisfies a compelling economic or social need that clearly and substantially outweighs the loss of or detriment to the benefit(s) of the Class I wetland. | Class II wetlands provide important wetland benefits, the loss of which is acceptable only in very limited circumstances. A permit shall be issued only if it is determined that the proposed activity satisfies a pressing economic or social need that clearly outweighs the loss of or detriment to the benefit(s) of the Class II wetland. | Class III wetlands supply wetland benefits, the loss of which is acceptable only after the exercise of caution and discernment. A permit shall be issued only if it is determined that the proposed activity satisfies an economic or social need that outweighs the loss of or detriment to the benefit(s) of the Class III wetland. | Class IV wetlands provide some wildlife and open space benefits and may provide other benefits cited in the act. Therefore, wanton or uncontrolled degradation or loss of Class IV wetlands is unacceptable. A permit shall be issued for a proposed activity in a Class IV wetland only if it is determined that the activity would be the only practicable alternative which could accomplish the applicant's objectives. |
Those concerns include:
If a proposed activity is inconsistent with physical health, or with any related laws, regulations and government policies, this would weigh against issuing a permit under the act until such conditions were met that would make the proposed activity consistent with these provisions.
