Lake Ave. Duluth MN 55802 kristofor.parson@state.mn.us 20220504 ArcGIS Metadata 1.0 withheld Impaired Streams Wholly Within Reservations, Minnesota, 2022 2022-05-04 Minnesota Pollution Control Agency Minnesota Pollution Control Agency This is a set of the impaired streams as determined by MPCA's surface water quality assessment process, submitted for the 2022 reporting cycle to the US Environmental Protection Agency (EPA). Streams declared impaired prior to 2022 are also included in this dataset unless they have been delisted or corrected. Note that for the purpose of submitting the impaired waters list to EPA, waterbodies partially or wholly within Indian reservation boundaries are published in separate datasets. The MPCA still considers these waters impaired and has an interest in restoring them. The MPCA respectfully requests that the waters partially or wholly within Indian reservations be symbolized differently on map products so that viewers can differentiate them from waters not intersecting Indian reservations. These streams are a subset and enhancement of the 1:24,000 scale National Hydrography Dataset (NHD). In cases where the NHD does not include a stream reach that MPCA has assessed, a feature is added by MPCA. Since the impaired streams are a small subset of the NHD, only that subset is included in the dataset. This dataset includes impaired streams which have not yet had a TMDL plan approved by the US EPA, those that have a US EPA approved TMDL plan as well as those waters that do not need a TMDL plan.

Detailed information regarding the impaired waterbodies is available in spreadsheet form here: http://www.pca.state.mn.us/index.php/view-document.html?gid=20225 These data reflect the state of the MPCA's surface water assessment database as of the dataset publication date. 2022-05-04 State of Minnesota These data have been audited to ensure every waterbody included in the 2022 list of impaired waters has a corresponding feature within this spatial dataset. Date of test: 3/29/2022 These data contain a feature for every waterbody in the proposed impaired waters dataset. High-resolution NHD is the primary dataset from which these features are drawn. If no feature exists in the NHD, the MN DNR division of waters lakes database is the source. The processes used to create and maintain high-resolution NHD data can be requested from MPCA. Because NHD data can be downloaded using several user-defined areas, the process descriptions can vary for each download. The NHDMetadata table contains a list of all the process descriptions that apply to a particular download, and those descriptions can be associated with the impaired waters polygons by MPCA staff upon request.

AUID: Assessment Unit ID. This AUID constitutes a unique identifer for each stream reach in the dataset. CAT: EPA Consolidation Assessment and Listing Methodology [CALM] category, which integrates the 305(b) Report with the 303(d) TMDL List. The five categories in CALM are as follows: Category 1: all designated uses are meeting water quality standards Category 2: some uses are meeting water quality standards and there are insufficient data to assess other uses Category 3: there are insufficient data to assess any uses Category 4: at least one use is impaired, but a TMDL is not required. Category 5: at least one use is impaired and a TMDL is required. These become the List of impaired waters. A reach can only be placed into one Category. For example, if a reach is impaired for one pollutant but the other uses are being met, and a TMDL is required, that reach would be placed into Category 5. Furthermore, if the reach is impaired for more than one pollutant, the reach must stay in Category 5 until ALL pollutants have EPA-approved TMDL plans. For 'bookkeeping' purposes Category 4 can be sub-divided, and has the following five sub-categories: 4A: Impaired, but a TMDL study has been approved by EPA 4B: Impaired, but a TMDL study is not required because water quality standards are expected to be met in the near future 4C: Impaired, but a TMDL study is not required because the impairment is not caused by a pollutant 4D: An assessment unit is impaired or threatened but doesn't require a TMDL because the impairment is due to natural conditions with only insignificant anthropogenic influence. To be considered 'insignificant', the elimination of the anthropogenic influence would not lead to the attainment of water quality standards and it would not be included in formal pollution reduction goal-setting activities. A reach-specific water quality standard based on local natural conditions has yet to be determined. Upon determination, the assessment unit will be considered non-impaired for the natural conditions and re-categorized to an appropriate category. 4E: Impaired or threatened but existing data indicates a TMDL is not required because impairment is solely a result of natural sources; a final determination of Category 4D will be made in the next assessment cycle pending confirmation from additional information (i.e. water quality or land use).
