Construction Permit Process - State Rules
How Are Wetlands Activities Regulated by Your State? The Department of
Environmental Protection (DEP) regulates activities impacting wetlands
under the authority of the Dam Safety and Encroachments Act and Dam
Safety and Waterway Management Rules and Regulations (Title 25,
Pennsylvania Code, Chapter 105). The Army Corps of Engineers has issued a Pennsylvania State
Programmatic General Permit # 2 (PASPGP-2). This permit is a federal
Clean Water Act, Section 404 Permit that authorizes the discharge of
dredge and fill material into waters of the United States. In most
instances, PASPGP-2 can be issued by the DEP or a county conservation
district with approved Chapter 105 water obstruction and encroachment
permits. PASPGP-2 eliminates the need for dual and often redundant state
and federal reviews, processing and permit issuance procedures.
Permit applications for work in wetlands, rivers, streams and other
waters will be reviewed by DEP or the delegated county conservation
district. Those applications for projects that have potential
significant environmental impacts will be forwarded to the Corps for
review. Applications not forwarded to the Corps will be processed
entirely by DEP or the delegated county conservation districts.
Mitigation Measures. The Department requires an applicant to
institute wetland replacement measures. Wetlands must be replaced at a
minimum area, function, and value ratio of 1:1.
Wetlands. Wetlands are "areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions, including swamps, marshes, bogs and similar areas."
Wetland Regulatory Background Information
Other Wetland Resources
Wetland Categories. The regulations distinguish between exceptional value wetlands and other wetlands.
Regulated Wetland Activities. A permit is necessary for the construction, operation, maintenance, modification, enlargement or abandonment of a dam, water obstruction, or encroachment. Certain activities do not require a permit, unless the Department finds they have a significant effect upon the safety or protection of the environment.
Exempt Wetland Activities. Some activities exempted from the Act are dams not exceeding 3 feet in height, the maintenance of an artificial pond or reservoir, water obstructions in streams or floodways with a drainage area of 100 acres or less, aerial crossing of a nonnavigable stream or wetland by electric or telephone lines, a dam subject to the requirements of the Mine Safety and Health Administration, maintenance of field drainage systems, and restoration activities.
