Full Breakdown
Henderson Municipal Code Chapter 13.04 prohibits any non-stormwater discharge into the city's MS4 storm drain system, including sewage, wash water, or pollutants like paint, oil, and yard waste. Construction sites disturbing an acre or more, and industrial facilities, must obtain NPDES permit coverage (Permit NVR100000 or NVR050000) and use best management practices before any discharge reaches the storm drain system. The public works director administers and enforces the chapter, with authority to inspect facilities, suspend MS4 access, and issue notices of violation.

Civil liability of $1,000-$10,000 per day per violation; criminal fine up to $1,000 per day and/or up to 6 months in the city detention center; city may recover attorney fees and remediation costs.
