Wisconsin's NR 151 sets statewide performance standards for construction site and post-construction stormwater runoff. DNR administers WPDES permits, and local programs must meet or exceed state minimums.
Wis. Stat. section 281.33 and Wis. Admin. Code NR 151 establish runoff management standards applicable to construction sites disturbing one acre or more, municipal separate storm sewer systems (MS4s), and certain land uses. Post-construction sites must reduce total suspended solids by 80 percent for new development. Construction operators must obtain a WPDES general permit, install erosion controls, and submit stormwater management plans. Municipalities designated as MS4s must implement six minimum control measures, including public education, illicit discharge detection, and post-construction controls. Local rules may be stricter but must satisfy NR 151 baselines.
DNR may issue notices of violation, daily forfeitures up to $10,000 under Wis. Stat. 281.98, stop-work orders, and require remediation of unauthorized discharges.
