Section 1: Overview

Originator:Minnesota Pollution Control Agency

Title: Wastewater Facility Discharge Locations in Minnesota

Abstract: This dataset represents the locations, classifications, and physical characteristics of NPDES and SDS wastewater facility discharge locations regulated by the Minnesota Pollution Control Agency. Tribal permits are administered at the federal level and not represented here.

Purpose: The attributes of wastewater facility discharge locations 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.

Field NameValid ValuesDefinitionDefinition Source
OBJECTID
-
Internal feature numberESRI
Shape
-
Feature geometryESRI
ITEM_ID
-
The unique ID that defines an item. master_ai_id + '-' + subject_item_category_code + subject_item_id
AI_ID
-
Tempo database ID for the wastewater treatment site, agency_interest_id
AI_NAME
-
The name of the wastewater facility.
AI_PROGRAM
-
MPCA programs that work with this outfall's facility.
AI_PRG_CODE
-
A list of MPCA program codes that work with this outfall's facility.
SI_DESIGNATION
-
The outfall's name. e.g. SD 001
DESCRIPTION
-
A description of the outfall.
SI_TYPE
-
subject_item_type_code. All locations in this data set represent surface discharge points and are coded as surface discharge (SURD).
SI_CAT
-
subject_item_category_code. All locations in this data set represent surface discharge points and are coded as monitoring (MONI).
SI_ID
-
subject_item_id. A numeric database identifier for internal database tracking.
SI_CAT_DESC
-
subject_item_category_desc. All locations in this data set represent surface discharge points and are called "Monitoring".
SI_TYPE_DESC
-
subject_item_type_desc. All locations in this data set represent surface discharge points and are called "Surface Discharge".
permit_number
-
The current wastewater permit number. These numbers may change over time as facilities switch from Individual (MN00) to General (MNG) permits.
per_status
-
Indicates if the permit is active or terminated. (Active, Inactive)
ACTIVITY_ID_PERMIT
-
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)
INT_DOC_ID_PERMIT
-
The internal record ID from the permits most recent issuance or termination.
per_doc_effective
-
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.
per_issued
-
The date from the most recent permit issuance or reissuance.
per_eff_start
-
The effective start date from the most recent permit issuance or reissuance. Typically the issued and effective start dates will be similar.
per_end_date
-
This date is a placeholder in the database and does not represent the end of the permit. Refer to the Permit Expiration date instead.
per_expiration
-
The date the permit expired. Permits remain in effective status past the expiration date unless terminated or withdrawn.
act_type_code
-
The activity type code. (permit issuance, reissuance, or termination activity)
act_type
-
The permit activity type description.
ind_vs_dom
-
indicates if the facility is an industrial or domestic WWTF
ownership
-
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
-
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_NPDES_CLASS
-
EPA Major / Minor status. Municipal EPA Majors have design flows over 1 mgd and Industrial Major status as determined by the EPA.
fac_design_flow
-
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.
flow_type_desc
-
The outfall's flow type. ( Intermittent or Continuous )
avg_anual_daily_flow_rate
-
Industrial outfalls: The authorized flow rate in million gallons/day for normal facility operations. Similar to avg daily flow rate.
avg_daily_flow_rate
-
Industrial outfalls: The authorized flow rate in million gallons/day for normal facility operations. Similar to avg annual daily flow rate.
avg_dry_weather_flow_rate
-
Municipal outfalls: Daily average flow in million gallons/day when the ground water is at or near normal and a runoff condition is not occurring.
avg_wet_weather_flow_rate
-
Municipal outfalls: The daily average flow in million gallons/day for the wettest 30 consecutive days for mechanical plants or for the wettest 180 consecutive days for controlled discharge pond systems. The 180 consecutive days for pond systems should be based on either the storage period from approximately November 15 through May 15 or the storage period from approximately May 15 through November 15.
max_daily_flow_rate
-
Industrial outfalls: The maximum authorized flow in million gallons/day.
which_months_code
-
Months the facility is required to monitor flow. Most frequently used for municipal and industrial pond discharges with seasonal discharge requirements.
