Summary
Nevada Division of Environmental Protection administers federal NPDES stormwater permits statewide under NRS 445A.300, requiring construction sites over one acre and industrial facilities to obtain coverage and implement pollution prevention measures.
NRS 445A.465 Injection of fluids through well or discharge of pollutant without permit prohibited; regulations. 1. Except as authorized by a permit issued by the Department pursuant to the provisions of NRS 445A.300 to 445A.730, inclusive, and regulations adopted by the Commission, it is unlawful for any person to: (a) Discharge from any point source any pollutant into any waters of the State or any treatment works. (b) Inject fluids through a well into any waters of the State. (c) Discharge from a point source a pollutant or inject fluids through a well that could be carried into the waters of the State by any means.

Full Breakdown
Under NRS 445A.300 through 445A.730 and the Clean Water Act, the Nevada Division of Environmental Protection issues general and individual NPDES permits for stormwater discharges. Construction activities disturbing one or more acres must obtain a Construction General Permit, prepare a Stormwater Pollution Prevention Plan (SWPPP), install best management practices, and conduct routine inspections. Industrial facilities in regulated sectors need a Multi-Sector General Permit. Municipal Separate Storm Sewer Systems (MS4s) in Clark and Washoe counties operate under permits requiring local stormwater ordinances. Local stormwater rules must meet or exceed state and federal minimums and cannot waive permit requirements.
Violations & Penalties
Discharge without a permit can result in civil penalties up to $25,000 per day per violation under NRS 445A.700, plus federal Clean Water Act penalties.
