Michigan Concentrated Animal Feeding Operations (CAFOs) Pre-2023
收藏资源简介：
A CAFO is an animal feeding operation that is regulated under the National Pollutant Discharge Elimination System (NPDES) permitting program. The NPDES program regulates discharges from point sources to surface waters, and under the Clean Water Act, CAFOs are considered point sources of pollution. This data includes regulated CAFOs in Michigan and features information about each site including its designated name, permittee name, permit status, total animals housed, how much waste it produces, how much land is available and used for CAFO waste application. This contains regulated CAFOs prior to 2023. To view CAFOs from report year 2023, view this open data layer. New layers will be added to the open data portal on a yearly basis. This data is utilized in the Regulated CAFO web map (item details). Learn more about EGLE's CAFO program by visiting Michigan.gov/CAFO.

集中动物饲养场（Concentrated Animal Feeding Operation，以下简称CAFO）是受《国家污染物排放消除系统（National Pollutant Discharge Elimination System，NPDES）许可计划》监管的动物饲养作业单位。NPDES计划依据《清洁水法（Clean Water Act）》监管点源向地表水的排放行为，且CAFO被认定为污染点源。本数据集涵盖密歇根州境内2023年之前的受监管CAFO，包含各场地的多项信息，包括指定名称、被许可方名称、许可状态、饲养动物总数量、产生的废物量、可用于CAFO废物土地施用的土地面积及实际使用面积。若需查看2023年报告年度的CAFO数据，请访问此开放数据图层。开放数据门户将按年度新增数据图层。本数据集已应用于《受监管CAFO网络地图》（项目详情）。如需了解密歇根州环境、五大湖与能源部（EGLE）的CAFO项目详情，请访问Michigan.gov/CAFO。 字段说明如下： X：站点经度（Site Longitude） Y：站点纬度（Site Latitude） OBJECTID：连续编号 SiteName：许可场地指定名称（Permitted Site Designated Name） SiteTypes：许可场地的类型标识（Designation for the type of site being permitted） PermitNumber：场地许可编号 PermitCategory：场地许可类型，分为通用许可覆盖范围、个体许可，或无排放潜力认定三类 COCPermitType：覆盖证书（Certificate of Coverage）项下的许可具体类别 PermitStatus：许可状态，包括有效、延期或过期 IssueDateFirstPermit：场地首张CAFO许可的签发日期 IssueDateMostRecentPermit：场地最新CAFO许可的签发日期 EffectiveDateMostRecentPermit：基于最新签发许可的CAFO许可生效日期 ExpirationDateMostRecentPermit：基于最新签发许可的CAFO许可过期日期 ReportYear：数据发布的日历年度 AnimalType：场地饲养的主要动物类型，若无主导动物类型则标注为“混合” MatureDairyCattle：报告年度内场地饲养的成年乳牛最大数量 CattleAllExceptMatureDairyCattl：报告年度内场地饲养的除成年乳牛外的其他所有牛只最大数量 VealCalves：报告年度内场地饲养的肉用小牛最大数量 SwineOver55lbs：报告年度内场地饲养的平均体重超过55磅的生猪最大数量 SwineUnder55lbs：报告年度内场地饲养的平均体重低于55磅的生猪最大数量 ChickensAllExceptLayers：报告年度内场地饲养的除蛋鸡外的其他鸡只最大数量 ChickenLayers：报告年度内场地饲养的蛋鸡最大数量 Turkeys：报告年度内场地饲养的火鸡最大数量 Horses：报告年度内场地饲养的马最大数量 WasteTotalDryTons：报告年度内场地产生的固态CAFO废物总量，单位为吨 WasteTotalLiquidGal：报告年度内场地产生的液态CAFO废物总量，单位为加仑 WasteSolidTransportedTons：报告年度内场地转运至场外的固态CAFO废物量，单位为吨 WasteLiquidTransportedGal：报告年度内场地转运至场外的液态CAFO废物量，单位为加仑 TotAcresAvailableLandApp：场地综合养分管理计划中可用于土地施用的土地总面积 CAFOTotalAcresUsed：报告年度内场地用于土地施用的土地面积 PermitteeName：被许可的个人或实体名称 PermitteeAddress：被许可方的街道地址 PermitteeCity：被许可方所在城市 PermitteeState：被许可方所在州 PermitteeZipCode：被许可方邮政编码 SiteAddress：场地街道地址 SiteCity：场地所在城市 SiteZipCode：场地邮政编码 County：场地所在县 Latitude：场地纬度（Site Latitude） Longitude：场地经度（Site Longitude） EGLEDistrict：依据场地所在县划定，负责场地许可合规监管的EGLE分区办事处
