Section 1: Overview

Originator:Minnesota Pollution Control Agency

Title: Wastewater Facilities in Minnesota

Abstract: This dataset represents the locations, classifications, and physical characteristics of NPDES and SDS wastewater facilities regulated by the Minnesota Pollution Control Agency. The locations represent the treatment building and this data set does not contain locations of influent, effluent, ambient, or land application monitoring locations. Tribal permits are administered at the federal level and not represented here.

Purpose: The attributes and locations of wastewater facilities provide information and context to support decisions on water quality, emergency management, and maintaining environmental quality. These data are intended to inform environmental research and public inquiries. These data represent the treatment location which may or may not match the effluent discharge monitoring location.

Table Detail:
Field NameValid ValuesDefinitionDefinition Source
Internal feature numberESRI
The unique ID that defines an item. master_ai_id + '-' + subject_item_category_code + subject_item_id
Tempo database ID for the wastewater treatment site, agency_interest_id
subject_item_category_code. All locations in this data set represent facilities and are coded as treatment (TREA).
subject_item_id. A numeric database identifier for internal database tracking.
The name of the wastewater facility.
The current wastewater permit number. These numbers may change over time as facilities switch from Individual (MN00) to General (MNG) permits.
The internal record ID from the permits most recent issuance or termination.
A y/n flag indicating if a permit is currently effective. This is similar to the field "per status" because only the most recent (effective) permit is shown for active permits. Permits remain in effective status until terminated.
The date from the most recent permit issuance or reissuance.
The effective start date from the most recent permit issuance or reissuance. Typically the issued and effective start dates will be similar.
This date is a placeholder in the database and does not represent the end of the permit. Refer to the Permit Expiration date instead.
The date the permit expired. Permits remain in effective status past the expiration date unless terminated or withdrawn.
Similar to the effective flag, this indicates if the permit is active or terminated. (Active, Inactive)
The system ID of the permit issuance, reissuance, or termination activity. Activity type (GEN = general, IND = individual), activity year (the year the permit issuance, reissuance, or termination was first drafted), activity number (a sequence number)
The activity type code. (permit issuance, reissuance, or termination activity)
The permit activity type description.

Total facility design flow in millions of gallons per day. This is the average wet weather for municipal permits and max daily for industrial permits. Null values are reflected in permit text and not included in this file.
proposed total facility design flow. Permits indicating construction or expansion during the current cycle will show new proposed design flow.
The type of flow represented. Typically municipal facilities use average wet weather flow, industrials use max daily flow, and station based means the value is reflected in permit text.
indicates if the facility is an industrial or domestic WWTF
indicates private, local, state, or federal government ownership of the facility. Tribal permits are issued at the federal level by the Environmental Protection Agency (EPA) and not represented here.

NPDES = National Pollution Discharge Elimination System and represents facilities discharging to surface water. SDS = State Discharge System and are facilities disposing of treated waste without discharging to surface water.
EPA Major / Minor status. Municipal EPA Majors have design flows over 1 mgd and Industrial Major status as determined by the EPA.
