US Army Corps of Engineers Reinstates Nationwide Permit #48 for Aquaculture Activities​

The Baltimore District, U.S. Army Corps of Engineers (Corps) has reinstated the suspended 2012 Nationwide Permit #48 (NWP #48) with revised regional conditions for new and existing commercial shellfish aquaculture activities in Maryland tidal waters. NWP #48 replaced the expired Regional General Permit-1 for commercial aquaculture activities, and is a required Federal permit issued in conjunction with State shellfish aquaculture leases for those who wish to farm shellfish in Maryland waters. The reinstated 2012 NWP #48 authorizes new and existing commercial shellfish aquaculture activities without acreage thresholds within Maryland waters pursuant to both Section 10 of the Rivers and Harbors Act of 1899 and Section 404 of the Clean Water Act. In addition, several changes were made to the District’s aquaculture permit review processes. The reinstated NWP#48 and revised regional conditions became effective in Maryland waters as of August 16, 2016. For more information and to review the full Special Public Notice regarding the reinstatement of the 2010 NWP #48, please visit Baltimore District Public Notice 16-47.

​US Army Corps of Engineers Maintenance Dredging

The Navigation Branch of the US Army Corps of Engineers Baltimore District posts information about all proposed maintenance dredging projects on their web page. Because dredging activities have the potential to impact nearby leaseholders by temporarily elevating localized sedimentation and/or limiting lease access with dredge support vessels, leaseholders should review project plans and determine if it may be necessary to take precautionary measures to protect product and equipment.

Current public notices are displayed in chronological order on the website. Click on the specific project link for a full viewing of the public notice documents and its associated drawings (if any) and on the project manager's name to send an email comment directly to the Project Manager. Comments made in reference to a public notice should include your name, address, and phone number as well as the public notice number or application number on all correspondence to the District. 

To access the Corp's maintenance dredging project public notices, please visit the Army Corps of Engineers Baltimore District's Navigation Branch website​.

Leaseholders who have an e-mail address on file with our Division will receive important information and announcements faster and in an eco-friendly way. Your email address remains confidential and will only be used for shellfish aquaculture related business. If you are an existing leaseholder and would like to sign-up, please send your name, lease number(s) and email address to or call 410-260-8648.

Department of Natural Resources Aquaculture Monthly Harvest Report Reminder

All leaseholders are reminded to check their records to make sure that monthly harvest reports are being submitted to the Department in a timely manner. Please recall that the terms of the Shellfish Aquaculture Harvester Permit (SAHP) require the primary Permittee/Leaseholder to submit a monthly harvest report to the Department even if you are not actively harvesting. Signed reports are due 10 days after the end of the month for which you are reporting. In order to keep your lease in active standing with the Department, please consult your records to ensure that you are in full compliance with our reporting requirements. Additional copies of the Harvest Report form may be printed from the "Fisheries Forms" page. If you are unsure if you are missing a report, please contact us to inquire about your status. Shellfish Aquaculture Harvester Permit renewal for 2019 may be delayed for those leases which still have missing 2018 reports at the end of this year.

Please promptly send any missing reports to:

Department of Natural Resources, Fishing and Boating Services
Shellfish Aquaculture Harvest Report
580 Taylor Avenue E-4
Annapolis, MD 21401

Or you may fax reports to: 410-260-8310 Attn: Aquaculture Harvest Report.
