The Lower Minnesota River has a dissolved oxygen impairment. During low flows, excess phosphorus generates algal blooms. Eventually, the algae die off and decompose. The decomposition process creates a shortage of the dissolved oxygen needed to sustain aquatic life.
In response to this impairment, the Minnesota Pollution Control Agency (MPCA) developed the Lower Minnesota River Dissolved Oxygen Total Maximum Daily Load (TMDL). The TMDL required the development of the Minnesota River Basin General Phosphorus Permit – Phase I. The purpose of the permit is to reduce phosphorus discharged by point sources to the Minnesota River Basin. The permit was issued on December 1, 2005.
The permit required the 40 larger existing continuously discharging wastewater treatment facilities in the basin to apply for coverage and receive a 5-Month Mass Phosphorus Limit. The permit also requires that all new and expanding continuously discharging phosphorus dischargers (even if they are not a wastewater treatment facility) within the basin to apply for permit coverage. Facilities covered by the Permit are subject to a 5-Month Mass Phosphorus Limit. The phosphorus limit is necessary to ensure that there is no net increase of phosphorus discharged to the basin. Stabilization ponds are subject to a different set of requirements. See the permit for details regarding requirements.

Permits and additions
Minnesota River Basin General Phosphorus Permit – Phase I (modified Dec. 1, 2009). This is the original permit issued on December 1, 2005. Appendix B of the Permit contains a list of the original 40 Permittees.
- Additions to Appendix B of the Minnesota River Basin General Phosphorus Permit – Phase I. This is the list of permittees added to Appendix B of the permit since the date of permit issuance.
- Phosphorus Limit Conversion Sheet (Pounds to Kilograms) for Facilities Listed in Appendix B of the Minnesota River Basin General Phosphorus Permit Phase 1. This document lists each permittee's 5-Month Mass Phosphorus Limits converted from pounds to kilograms. The permit listed phosphorus limits in pounds, but should have listed the limits in kilograms. This conversion sheet is necessary since the permit requires reporting phosphorus discharges in kilograms.
Permit forms
Permit Application Form. Application for coverage under the Minnesota River Basin General Phosphorus Permit – Phase I. Facilities in the basin are not covered by the Permit until the application form is completed and submitted and the facility has received a Notification of Coverage from the MPCA.
- Legal Contract-to-Trade Forms for Transfers of Jordan Trading Units. Permittees (i.e., those listed in Appendix B of the permit) have the option of buying or selling phosphorus credits according to the terms of the permit. Permittees may trade facility to facility (one buyer and one seller) or trade through a Trade Association (multiple facilities trading with an aggregate limit). In order to implement a trade, the trading partners must fill-out, sign and submit the appropriate trade form. There are four trade types and thus four types of forms. The first form type is for facility to facility trades. The last three forms are used if a Trade Association is involved in the trade.
- Legal Contract to Trade Form A Transfer of Jordan Trading Units Between Individual Permittees. Use this form for all trades made between two individual Permittees. The form has the following three formats: PDF, Word, or online auto-fill. Each format has the same content. You may submit the form in whatever format that meets your needs. If both parties to the trade are already listed in Appendix B of the Basin Permit, we recommend that you use the auto-fill version because it automatically fills in much of the required information. If either of the facilities in the trade is not currently listed in Appendix B of the Permit, the auto-fill version of the trade form will not work for that trade. In that case, use either the Word or the PDF version of the form and manually enter and calculate required information.
- Example of filled-out “Transfers Between Individual Permittees” trade form.
- Trade Association—Internal Trading. Used only for internal trades made within a Trade Association by its members.
- Example of filled-out Trade Association-Internal Trading form.
- Trade Association—Between Trade Association and an Individual Permittee. For trades made between a Trade Association and a single Permittee that is not in a Trade Association.
- Example of filled-out Trade Association-Between Trade Association and an Individual Permittee form.
- Trade Association—Trade Association to Trade Association. Used only for trades made between two Trade Associations.
- Example of filled-out Trade Association-Trade Association to Trade Association form.
- Exclusion Application Form - Exclusions from Phosphorus Limit, PIP and Annual Compliance Report. For Permittees which are requesting an exclusion from their 5-Month Mass Phosphorus Limit, Pre-season Implementation Plan (PIP) and Annual Compliance Report requirements (Requirements).
- Pre-season Implementation Plan (PIP). Facilities which are listed in Appendix B of the Minnesota River Basin General Phosphorus Permit are required to submit a PIP unless they have obtained an exclusion from their 5-Month Mass Phosphorus Limit.
- Example of filled-out PIP form.
- Annual Compliance Report Forms (ACR). Facilities which are listed in Appendix B of the Minnesota River Basin General Phosphorus Permit are required to submit an ACR unless they have received an exclusion from their 5-Month Mass Phosphorus Limit. ACR Form A is used for Permittees which are not in a Trade Association. ACR Form B is used for Permittees which are a member of a Trade Association.
- Annual Compliance Report – Form A For Permittees not in a Trade Association. The form has the following three formats: pdf, Word, or online auto-fill. Each format has the same content. You may submit the form in whatever format that meets your needs. We recommend that you use the auto-fill version of the form because it automatically fills in much of the information required by the form.
- Annual Compliance Report Form B - for facilities with membership in a Trade Association
