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 expiring Regional General Permit-1 for commercial aquaculture activities. The reinstated NWP#48 is effective in Maryland waters as of August 16, 2016, until it expires March 18, 2017. The Corps will issue a public notice when the Nationwide Permits are re-issued. Please visit the Baltimore District Aquaculture Page for more information about the changes to the Corps' permitting process under the NWP#48


US Army Corps of Engineers maintenance dredging schedule for Federal FY17

The Department of Natural Resources Aquaculture Division would like to inform leaseholders of the US Army Corps of Engineers Baltimore District maintenance dredging schedule for Federal FY17 (Oct 1, 2016 - Sept 30, 2017). 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 is necessary to take precautionary measures to protect product and equipment. Areas scheduled for maintenance dredging in Maryland waters in FY17 include the Wicomico River (Wicomico County); Twitch Cove and Big Thorofare on Smith Island (Somerset County); the Inlet at Ocean City; and various Federal channels into Baltimore Harbor. There is also a Small Navigation Project involving channel realignment and jetty and stone sill installation proposed for Rhodes Point, Smith Island.

For additional information and copies of the Corp's maintenance dredging project public notices, please visit the Army Corps of Engineers Baltimore District's Navigation Branch website​. Notices for all sites may not yet be posted.

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 2018 may be delayed for those leases which still have missing 2017 reports at the end of this year.
