Permits help the MPCA protect the environment. A permit sets detailed goals for specific activities, including:

  • Preventing, controlling, or cleaning up pollution
  • Limiting releases of pollutants
  • Directing construction or operation of a facility
  • Controlling storage, collection, transport, and processing of waste

The MPCA's water monitoring data are critical to writing reasonable and accurate permits. Our permit writers have to know the condition of water that will receive a facility's discharges to set appropriate limits in that facility's permit.
