NVG201000 was developed to authorize a range of DeMinimis water discharges under one permit; it establishes Notice of Intent (NOI) requirements, water quality limitations, prohibitions and management practices for five (5) separate discharge categories. Discharges from the following activities are considered DeMinimis when they are consistent with provisions included in this permit.

Discharge Category 1— Public Water System Emergency discharges - Permitted Public Water System Emergency discharges are situations which pose an immediate risk to health, life, property or environment.

Discharge Category 2 — Water supply systems discharges - Permitted discharges include discharges related to construction, maintenance, and testing (quantity, duration and capacity) of water supply systems (including the pipes, tanks, and reservoirs) such as:

  • Disinfection and flushing activities;
  • Discharges resulting from pressure releases, or overflows;
  • Discharge from wells and storage reservoirs

Discharge Category 3 — Well testing & maintenance / aquifer testing / water quality testing - Permitted water discharges include discharges of water associated with:

  • Drilling of new water or geothermal wells;
  • Rehabilitation or maintenance of water or geothermal wells, piezometers, and boreholes;
  • Water supply quantity or quality evaluations;
  • Well/aquifer test pumping and/or purging;
  • Discharges from any borehole not fully developed.

Discharge Category 4 — Subsurface water discharges - Permitted water discharges include:

  • Groundwater from foundation, footer drain, basement, underground structure or other dewatering, provided the discharge is not contaminated with pollutants, chemicals or co-mingled with other wastewaters;
  • Water from intercepted or pumped groundwater.

Discharge Category 5 — Utility vault water discharges - Permitted water discharges include:

  • Groundwater or surface water collected in vaults;
  • Water from subterranean seepage;
  • Snow melt, stormwater, or water present as a result of inclement weather.
  • If you are proposing a discharge in any of the activities described above, you may do so under general permit NVG201000 coverage. The Nevada DeMinimis permitting program was designed for electronic NOI submissions. Anyone seeking coverage under general NPDES permit NVG201000 shall apply electronically - unless a waiver is requested and granted in writing by the Division.

    Qualifying dischargers shall not begin to discharge until the Division has received and approved the original complete and signed NOI, applicable fees, and associated acceptable results of the water quality samples taken in accordance with Section A of the permit. Existing dischargers who are covered under a current NDEP permit may continue to discharge until valid permit expires. Discharges who are not granted coverage under this general NPDES permit because the nature, quality and quantity of the proposed discharge, may apply for an individual NPDES permit.
