Las Cruces is a regulated small MS4 under EPA's NPDES general permit NMR040000. Development and construction sites must control runoff, prevent illicit discharges into arroyos and the Rio Grande, and follow the city's Design Standards for drainage.
The City of Las Cruces operates a Municipal Separate Storm Sewer System regulated under EPA's small-MS4 general permit NMR040000, which requires illicit-discharge controls, public education, and post-construction stormwater management. Construction sites disturbing one acre or more must obtain coverage under the EPA Construction General Permit and prepare a Stormwater Pollution Prevention Plan (SWPPP). On-site drainage, retention, and conveyance to arroyos follow the Las Cruces Design Standards (Chapter 32). Because monsoon storms produce flash runoff across the desert, the city is a Class 7 CRS community and enforces dumping and illicit-discharge prohibitions into gutters, arroyos, and storm drains.
Illicit discharges to storm drains or arroyos and uncontrolled construction runoff trigger stop-work orders, city citations, and federal Clean Water Act enforcement with substantial civil penalties.
