Full Breakdown
Chapter 941, Storm Water Discharge Control, sets Toledo's construction-site erosion and sediment rules. 12(a) requires notice to the Division of Environmental Services three days before construction activities begin. 12(d)(2). 12(d)(3); once approved, the SWP3 stays valid for 18 months or until construction is complete. Subsection (h) requires applicants to assign qualified inspection personnel to self-inspect all BMPs at least once every seven calendar days and again within 24 hours of any storm event exceeding one-half inch of rain in 24 hours, checking disturbed areas, discharge points, and vehicle-tracking locations, and to keep inspection records for three years after final stabilization.
Subsection (i) sets repair timelines once an inspection finds a deficiency: general control practices must be fixed within three days, sediment-settling ponds within ten days, and any newly required control practice installed within ten days. Final stabilization is determined by the Division of Engineering Services, and the Director may issue stop-work orders for uncorrected violations.

Missing the three-day construction notice draws a civil penalty up to $100 under § 941.08(b). Violating an NPDES permit condition carries civil penalties up to $25,000 per day per violation; other chapter violations, including uncorrected BMP deficiencies, carry up to $2,500 per day under § 941.08(a). Violators are also liable for the City's cleanup and monitoring costs, and uncorrected conditions can be declared a public nuisance subject to summary abatement, with a stop-work order violation charged as a third-degree misdemeanor.
