Full Breakdown
Under Clark County Code Chapter 24.40, it's unlawful to discharge any non-stormwater into the county's storm sewer system without NDEP authorization and county manager approval, or to dump trash, construction debris, industrial waste, or sewage into it. Illicit connections to the system are also banned. The county manager can inspect premises, require monitoring equipment, and mandate Best Management Practices at construction sites and industrial facilities to meet the county's NPDES MS4 permit. This governs unincorporated Clark County within the Las Vegas Valley, not Las Vegas, Henderson, North Las Vegas, Boulder City, or Mesquite, which enforce their own codes, but it does reach the unincorporated Strip resort corridor in Paradise and Winchester.
Violations & Fines
Violations are a public nuisance per se, punishable by a misdemeanor citation (up to $1,000 fine and/or 6 months jail) plus civil penalties of up to $1,000 per day per violation, with each day a separate offense.
