PreApplication/PreFiling Meetings

The Maryland Department of the Environment (MDE) believes that a PreApplication meeting is an excellent opportunity to find out what information is necessary to submit a complete application. Experience shows that the submission of a complete application results in an expeditious review of a project, while an incomplete application often results in processing delays.

Furthermore, if you are required or have been notified that your project requires that you request a Water Quality Certification (WQC) under Section 401 of the Clean Water Act (CWA) from MDE for any activity that may result in a discharge to waters of the United States, then in accordance with 40 C.F.R. § 121.4, at least 30 days prior to submitting a WQC request, you must request a Pre-Filing Meeting with MDE. While MDE is not obligated to grant the request, you may not file a request for a WQC from MDE until you have filed a Pre-Filing Meeting Request with MDE and 30 (thirty) days have passed. (See MDE’s WQC webpage for more information.)

Meeting with a project manager, who is familiar with your area and knowledgeable about the regulatory process, prior to submitting an application helps identify informational requirements and potential pitfalls in the application review process. A PreApplication or Pre-Filing meeting highlights review procedures and provides guidance on the information necessary to advance the project, including the need for detailed engineering studies, natural resource assessments, and mitigation requirements.

In addition, submitting the information requested in the PreApplication Meeting or Pre-Filing Meeting Request Form will help determine if your proposal is a major or minor project.  MDE will also be able to provide you with an estimate of the processing time and costs, including application, processing, and impact fees, if required.

To schedule a PreApplication/Pre-Filing meeting for proposed activities in tidal wetlands, nontidal wetlands, or a nontidal waterway, including the 100-year nontidal floodplain, please go to the link below and complete and submit the applicable PreApplication or Pre-Filing Meeting Request  form.  You will be contacted to set-up an appointment.

Coldwater Resources Mapping Tool, a Geographic Information Systems (GIS) based interactive map


    The Maryland Department of the Environment is providing applicants with access to the Maryland Department of Natural Resources (DNR) Coldwater Resources Mapping Tool* so that applicants can determine if their project may be proposed in an area that may have trout and/or other coldwater species and to advise your planning process.

    This mapping tool has several layers which users can turn on or off. By clicking on a watershed within the map, an applicant will be able to determine if their project is in a location with potential coldwater resources and will be provided contact information for local DNR biologists.

    Permit applicants are encouraged to consult the local DNR fisheries biologist for site specific information on coldwater fish and benthic macroinvertebrate species. To access the DNR’s Coldwater Resources Mapping Tool please visit the following link:

    *Maryland Department of Natural Resources has made every attempt to provide accurate and up to date information on this mapping tool. DNR cannot be held responsible for the misuse or misinterpretation of any information and offers no warranty guarantees or representations of any kind in connection to its accuracy or completeness. DNR accepts no liability for any loss, damage or inconvenience caused as a result of reliance on the GIS application. The use of this GIS application during the pre-screening process does not forego additional resource screening that will occur at later stages. Maryland Department of the Environment and Maryland Department of Natural Resources' Environmental Review Program will further review the project if a species of concern is encountered in the associated watershed.
