How to apply for a permit in Pennsylvania

For work in Pennsylvania, use the Pennsylvania Department of Environmental Protection and U.S. Army Corps of Engineers Joint Application. You may also write or call the office below for an application. It is important that you provide complete information in the application, as requested. 

Pennsylvania Department of Environmental Protection
Bureau of Dams, Waterways and Wetlands
Rachel Carson State Office Building
Market Street
Harrisburg, Pennsylvania 17105
(717) 787-6827

The Process: After the state or Corps office receives the application, it will be assigned an identification number. Then within 15 days of receipt of all the required information, a determination will be made regarding the type of permit required. Depending on the type of permit process, a public notice will be issued with a 15-day to 30-day comment period, if necessary. The proposal is reviewed by the Corps, general public, special interest groups, and state, local and other related federal agencies. After the comment period, the Corps reviews all comments, and may consult other federal agencies. The Corps may ask you for additional information and conduct a public hearing, if needed. For individual permits, when all considerations are satisfied, the District Engineer makes a decision to either issue or deny the permit application. You will than receive a permit or written explanation of the reason for denial. For State Programmatic General Permits, this federal permit is usually issued along with the State's authorization.

Permits Types and Processes

The U.S. Army Corps of Engineers, Baltimore District authorizes work in waters of the United States under four types of permits: State Programmatic General Permits, Nationwide Permits, Letters of Permission, and Individual Permits.

Regional General Permits
In the Baltimore District, we use two types of Regional General Permits: State Programmatic General Permits (PA & MD only) or Nationwide Permits that are reserved for only the most minor impacts to waters of the United States regulated by the Corps. For projects with the potential for substantial environmental impacts, we use either Letters of Permission or Individual Permits.

The level of review increases substantially from Regional General Permit review to Individual Permit Review. Within the Baltimore District, project managers will try to work with applicants to make sure that any impacts to waters or wetlands are avoided to the most practicable extent to best preserve our aquatic resources and to help enable applicants to qualify for the most expeditious review.

State Programmatic General Permits

Pennsylvania State Programmatic General Permit-6 (PASPGP-6)

PASPGP-6 (click to access full permit) Authorizes work in waters of the United States within portions of the state of Pennsylvania for activities that would cause no more than minimal adverse environmental effects, individually and cumulatively, subject to the permit’s specific terms and conditions.  This programmatic general permit operates in conjunction with Pennsylvania’s Department of the Environment’s (PADEP) state regulatory program that protects the aquatic environment in a manner equivalent to the Department of the Army regulatory program. PASPGP-6 became effective July 1, 2021 and will expire June 30, 2026. 

View the June 25, 2021 public notice regarding the issuance of PASPGP-6. 

Pennsylvania State Programmatic General Permit-5 (PASPGP-5)

PASPGP-5 (click to access full permit) authorizes work in waters of the United States within portions of the state of Pennsylvania for activities that would cause no more than minimal adverse environmental effects, individually and cumulatively, subject to the permit’s specific terms and conditions. This programmatic general permit operates in conjunction with Pennsylvania’s Department of the Environment’s (PADEP) state regulatory program that protects the aquatic environment in a manner equivalent to the Department of the Army regulatory program. PASPGP-5 became effective July 1, 2016, was revised in July 2018, and will expire June 30, 2021.  

View the May 2, 2016 public notice regarding the issuance of PASPGP-5. View the July 30, 2018 public notice regarding the modification of PASPGP-5.  

Nationwide Permits

Nationwide Permits (NWPs) are general permits issued on a nationwide basis to authorize minor activities with minimal evaluation time. NWPs have been established to reduce the regulatory reporting burden for specific activities that have no more than minimal impacts to the aquatic environment.  Most NWPs have been suspended in Maryland and the Baltimore and Philadelphia District’s area of responsibility within Pennsylvania since the State Programmatic General Permits provide comparable Department of the Army authorization.

On January 13, 2021, the U.S. Army Corps of Engineers (Corps) published a final rule in the Federal Register (86 FR 2744) announcing the reissuance of 12 existing nationwide permits (NWPs) and four new NWPs, as well as the reissuance of NWP general conditions and definitions with some modifications. These 16 NWPs will go into effect on March 15, 2021, and will expire on March 14, 2026:

  • NWP 12 – Oil or Natural Gas Pipeline Activities
  • NWP 21 – Surface Coal Mining Activities
  • NWP 29 – Residential Developments
  • NWP 39 – Commercial and Institutional Developments
  • NWP 40 – Agricultural Activities
  • NWP 42 – Recreational Facilities
  • NWP 43 – Stormwater Management Facilities
  • NWP 44 – Mining Activities
  • NWP 48 – Commercial Shellfish Mariculture Activities
  • NWP 50 – Underground Coal Mining Activities
  • NWP 51 – Land-Based Renewable Energy Generation Facilities
  • NWP 52 – Water-Based Renewable Energy Generation Pilot Projects
  • NWP 55 – Seaweed Mariculture Activities
  • NWP 56 – Finfish Mariculture Activities
  • NWP 57 – Electric Utility Line and Telecommunications Activities
  • NWP 58 – Utility Line Activities for Water and Other Substances

‚ÄčThe 12 existing NWPs published in the January 13, 2021 final rule replace the 2017 versions of these NWPs. The 2017 versions of NWPs 12, 21, 29, 39, 40, 42, 43, 44, 48, 50, 51, and 52 expire on March 14, 2021.

On March 5, 2021, the Baltimore District issued Special Public Notice 21-08, announcing the final suspensions and regional conditions for these 16 2021 NWPs in the State of Maryland, the Commonwealth of Pennsylvania, and the District of Columbia.  The Norfolk District regional conditions are applicable for the military installations in Commonwealth of Virginia within the Baltimore District’s area of responsibility (i.e., Fort Belvoir, Fort Myer, and the Pentagon) and can be found at:  https://www.nao.usace.army.mil/Missions/Regulatory/.  The suspensions and regional conditions for these 16 2021 NWPs are documented below:

The 40 remaining 2017 NWPs continue to be in effect under the January 6, 2017 final rule, the district regional conditions, and the Water Quality Certifications, and Coastal Zone Management Act consistency concurrences made for that rule. The regional conditions for the 40 existing 2017 NWPs were previously announced in Special Public Notice #17-14 and are applicable to the State of Maryland, the Commonwealth of Pennsylvania within the Baltimore and Philadelphia District’s regulatory geographic boundaries, the District of Columbia, and certain military installations of northern Virginia (i.e., Fort Belvoir, Fort Myer, and the Pentagon).  The suspensions and regional conditions for the 2017 NWPs are documented below:

Letter of Permission

A Letter of Permission (LOP), as described in 33 CFR 325.2(e)(1), is a type of standard permit issued through an abbreviated processing procedure that includes coordination with federal and state resource agencies and a public interest evaluation, but without the publishing of an individual public notice. LOP will not be used to authorize the transportation of dredged material for the purpose of placing it in ocean waters. 

For projects subject to Section 10 of the Rivers and Harbors Act of 1899, LOPs may be used when the District Engineer has concluded that the proposed work would be: 1) minor; 2) would not have significant individual or cumulative impacts on environmental values; and 3) should encounter no appreciable opposition. 

For projects subject to section 404 of the Clean Water Act, LOPs may be used after the District Engineer: 1) consults with federal and state fish and wildlife agencies, the Regional Administrator, Environmental Protection Agency, the state water quality certifying agency and, if appropriate, the state Coastal Zone Management Agency, to develop a list of categories of activities proposed for authorization under LOP procedures; 2) issues a public notice advertising the proposed list and LOP procedures, requesting comments and offering an opportunity for public hearing; and 3) the 401 certification has been issued or waived and, if appropriate, CZM consistency concurrence obtained or presumed either on a generic or individual basis.

Individual Permits

Individual permits (IPs - also known as a standard permits - SPs) are generally reserved for projects with potential for substantial environmental impacts. An IP requires a full public interest review, including public notices and coordination with involved agencies, interested parties and the general public.

 Appeals

The Corps of Engineers has an administrative appeal process whereby applicants and landowners may appeal denied permits, issued permits that contain requirements that are unacceptable to the applicant, or approved jurisdictional determinations. Although these decisions are made by Corps District offices, requests for appeals of such decisions are appealed to the Corps Division offices. Requests for appeal must be furnished to the Division office within 60 days of the date of the appealable decision. A site visit or an appeal conference or meeting may be conducted during the appeal process. A decision on the merits of the appeal based on the administrative record is normally made in 90 days. The Division will either uphold the District decision or send the case back to the District, with direction to make a new decision.

Procedures for appealing Corps permitting decisions are found at 33 CFR Part 331.
