MaineDMR Public Health - 2018 NSSP Classifications

The 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 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 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 2018. Data projection is NAD 1983 UTM Zone 19N.海洋资源部（Department of Marine Resources, DMR）公共卫生分局依据海岸线调查结果与沿海水域粪大肠菌群监测数据，对贝类养殖区的采收适宜性开展分级工作。在海岸线调查过程中，DMR工作人员会记录缅因州沿岸存在的各类污水污染源。基于此类调查与监测信息，所有贝类养殖区将依照美国国家贝类卫生计划（National Shellfish Sanitation Program, NSSP）制定的标准划分为五类：获准类（Approved）、有条件获准类（Conditionally Approved）、限制类（Restricted）、有条件限制类（Conditionally Restricted）以及禁止类（Prohibited）。该计划是一项联邦与州政府合作项目，为所有参与跨州贝类采收与销售的州制定相关合规要求。如需了解更多贝类养殖区分级的相关信息，请访问：https://www.maine.gov/dmr/shellfish-sanitation-management/programs/growingareas/index.html。本数据集收录了截至2018年缅因州全部贝类养殖区的分级信息。数据投影采用NAD 1983 UTM Zone 19N坐标系。
