MaineDMR Public Health - 2019 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 2019. Data projection is NAD 1983 UTM Zone 19N.海洋资源部（Department of Marine Resources，简称DMR）公共卫生分局会基于海岸沿线调查以及沿海水域粪大肠菌群监测的结果，对贝类养殖区的捕捞适宜性进行分级。在海岸沿线调查过程中，该部门工作人员会记录缅因州沿岸各类污水污染源的分布情况。基于上述调查信息，所有贝类养殖区将按照国家贝类卫生计划（National Shellfish Sanitation Program，简称NSSP）制定的标准划分为五类：核准区（Approved）、条件核准区（Conditionally Approved）、限制区（Restricted）、条件限制区（Conditionally Restricted）以及禁止区（Prohibited）。该计划作为联邦与州级合作项目，为所有参与跨州贝类捕捞与销售的州制定相关规范要求。如需了解更多贝类养殖滩涂分级的相关信息，请访问：https://www.maine.gov/dmr/shellfish-sanitation-management/programs/growingareas/index.html。本数据集涵盖了截至2019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。
