In addition, near-shore areas (shallow waters up to approximately 200 feet from shore) may appear as approved on the map because of inadequate resolution. If no health risk is apparent, the area remains open to shellfish harvesting. Relay can occur only outside of oyster season and when water temperatures are above 50ºF. Harvesters are notified of conditional closings daily by an announcement broadcast by the Maryland Natural Resources Police made at 5, 6, and 7 a.m. on VHF radio band 14, by calling toll free 1-800-541-1210, or by visiting this web site for the daily advisory on conditionally approved shellfish areas. Detailed information regarding wet storage can be found in the current edition of the. Harvest-limited shellfish waters for selected estuaries, 1971-1985 Chart showing how the Chesapeake Bay is limited in the amount of shellfish compared to other east coast bay. Through both sustainable commercial production and restoration activities, the initiative aims to get more shellfish back in the water. State responsibilities include adopting laws and regulations for the sanitary control of shellfish and the shellfish industry, formulating comprehensive shellfish harvesting area surveys and adopting control measures to ensure that shellfish are grown, harvested and processed in a safe and sanitary manner. The NSSP Guide is incorporated by reference in COMAR 10.15.07.01. All of the waters lying within the confines of any marina are restricted for the harvesting or storing of shellfish. With ongoing research programs spanning from the estuarine waters of the Chesapeake Bay to the open waters of the world’s oceans, Horn Point is a national leader in applying environmental research and discovery to solve society’s most pressing environmental problems. Yesterday’s water sampling of the Potomac River in Southern Maryland confirmed that the bloom of Dinophysis acuminata, a potentially harmful algae, continues. These areas are included in the descriptions that follow and are noted as "Closed Safety Zone/ prohibited". Through the efforts of this extensive program, Maryland has enjoyed an excellent reputation as a source of safe and wholesome shellfish products to seafood lovers throughout the nation and the world. Wet storage in natural bodies of water or flow through systems on land shall not treat the water used for wet storage. A diverse range of resident and migratory finfish and shellfish species inhabit tidal portions of the Chesapeake Bay and its tributaries, coastal bays, and coastal waters. State responsibilities include adopting laws and regulations for the sanitary control of shellfish and the shellfish industry, formulating comprehensive shellfish harvesting area surveys and adopting control measures to ensure that shellfish are grown, harvested and processed in a safe and sanitary manner. The applicant must allow MDE, MDH or DNR access to the site for field review if necessary. Maryland is a member of the Interstate Shellfish Sanitation Conference (ISSC), a voluntary, cooperative association of states, the shellfish industry, U.S. Food and Drug Administration (FDA), National Oceanic and Atmospheric Administration (NOAA), and Environmental Protection Agency (EPA). This effort has three parts: 1) identifying and eliminating pollution sources, 2) collecting water samples for bacteriological examination; and 3) examining shellstock samples for bacteriological contamination and chemical toxicants. FDA is also responsible for the audit of each state shellfish control program to determine conformity with the NSSP standards and guidelines. To protect this valuable resource and safeguard public health, the state conducts several important regulatory programs to ensure harvests of clean, wholesome shellfish. When the conditions causing the water quality to be of lesser quality can be predicted, a management plan can be established which will allow harvesting when the water quality meets the criteria for the approved classification. Maryland participates in the National Shellfish Sanitation Program (NSSP) to protect public health and to assure oysters and clams are harvested from areas that are safe. The following information must be included on the application: Wet Storage in Land-based Re-circulating Systems, For more information concerning shellfish harvesting, contact MDE's Water and Science Administration(WSA) at (410) 537-3818 or the Natural Resources Police at (410) 260-8880. FDA reviews methods for shellfish sanitation inlcuding for classification and management of shellfish areas proposed by the ISSC, and incorporates those methods consistent with standard health practice into the National Shellfish Sanitation Program (NSSP) Model Ordinance. 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.

Also, all waters lying adjacent to marina facilities located in shellfish waters of the State and capable of accommodating ten (10) or more vessels are restricted for the harvesting or storing of shellfish between May 1st and September 30th of each year. MDH conducts inspections of the wet storage site for proper product handling, lot identification, tagging, and shipping (trace back) records at least two times a year. The Resource Investigation of the pollution of tidal waters of Maryland and Virginia : with special reference to shellfish-bearing areas, by Hugh S. Cumming ; prepared by direction of the Surgeon General Investigation of the pollution of tidal waters of Maryland and Virginia : with special reference to shellfish-bearing areas, by Any changes to the plan must be approved by MDH prior to making the change. Conditionally approved means that oysters and clams can be directly harvested except for the three days following a rainfall of an inch or greater in twenty-four hours. The basic concept of the National Shellfish Sanitation Program (NSSP) is to control the safety of shellfish by preventing the harvest of shellstock from polluted harvest areas. The basic concept of the National Shellfish Sanitation Program (NSSP) is to control the safety of shellfish by preventing the harvest of shellstock from polluted harvest areas. All other times, they can be harvested. Prohibited means that the harvest of shellstock for any purpose is not permitted. These factors may include sources of potential and actual pollution (failing septic systems, animal wastes from agricultural properties, wastewater treatment plants, industrial waste, surface-runoff from polluted areas), bacterial quality of the water and shellfish, hydrographic characteristics of shellfish growing areas, and general land-use patterns. Flow through systems may only use waters from approved or conditionally approved growing areas and are not authorized to treat the water from the growing area. holding conditioning, or increasing salt content) and any species-specific physiological factors that may affect design criteria. A plan and details for monitoring the sanitary quality of the process water. Harvest areas regulated under these management plans are placed in the conditionally approved classification. With the exception of certain species of water fleas (order Cladocera), Branchiopods are found in any relatively shallow continental waters such as freshwater and brackish lakes, and bays. Maryland is a member of the Interstate Shellfish Sanitation Conference (ISSC), a voluntary, cooperative association of states, the shellfish industry, U.S. Food and Drug Administration (FDA), National Oceanic and Atmospheric Administration (NOAA), and Environmental Protection Agency (EPA). This determination was based on an investigation and extensive data analysis done in 1987.

Many of these species sustain valuable commercial and recreational fisheries. The certified dealer and the location is listed in the Interstate Certified Shellfish Shippers List (ICSSL) as “WS” by MDH, and a “WS” designation is added to their Food Processing Plant license number. Prior to construction or remodeling of a re-circulating system, a wet storage application must be submitted to MDE. When all three Departments are satisfied that the NSSP requirements are met the proposed wet storage activity can be authorized, a Wet Storage Authorization is issued by MDE. The results of this study will also be useful for management of shellfish aquaculture, a growing industry in Maryland waters. Request for relay of oysters or clams from restricted waters to approved waters must be made in writing to MDE in advance of possible relay dates.
