MaineDMR Public Health - 2020 NSSP Classifications

The Maine Department of Marine Resources (DMR) Bureau of Public Health classifies shellfish growing areas for harvest suitability based on the results of a shoreline survey and fecal coliform bacteria monitoring in coastal waters. During a shoreline survey, DMR staff document the presence of wastewater pollution sources along Maine's coast. Based on this information, each growing area is classified as either Approved, Conditionally Approved, Restricted, Conditionally Restricted or Prohibited using standards set by the National Shellfish Sanitation Program (NSSP), a federal/state cooperative program that sets the requirements for all states involved in interstate shellfish harvest and sale. For more information about the classification of shellfish flats, visit https://www.maine.gov/dmr/shellfish-sanitation-management/programs/growingareas/index.html. This dataset contains the classification for all shellfish growing areas in Maine through 2020. Data projection is NAD 1983 UTM Zone 19N.缅因州海洋资源部（Maine Department of Marine Resources，DMR）公共卫生局依据海岸线调查结果与沿海水域粪大肠菌群监测数据，对贝类养殖区的收获适宜性进行分级评定。在开展海岸线调查期间，DMR工作人员会记录缅因州沿海沿岸的废水污染源分布情况。基于上述调查信息，参照由联邦与州合作组建的全国贝类卫生计划（National Shellfish Sanitation Program，NSSP）制定的分级标准，各养殖区将被划分为核准级、有条件核准级、限制级、有条件限制级以及禁止级五类。该计划为所有涉及跨州贝类捕捞与销售的州制定了相关从业要求。如需了解更多贝类养殖区划分级的相关信息，请访问https://www.maine.gov/dmr/shellfish-sanitation-management/programs/growingareas/index.html。本数据集收录了截至2020年缅因州全部贝类养殖区的分级信息。该数据集采用NAD 1983 UTM 19N坐标系进行投影。
