IN HB1348

Commercial facilities, food establishments, and mobile food establishments discharging fats, oils, and grease (FOG) into sewer systems must install and operate properly sized grease control equipment designed or approved by a licensed professional engineer or architect, effective July 1, 2026.

Utilities and regulating authorities are prohibited from imposing blanket grease control mandates or requiring specific types, sizes, or locations of equipment if a regulated entity already has properly maintained equipment that prevents FOG discharges exceeding allowable concentrations.

Regulated entities must maintain records for 2 years documenting haul dates, FOG volumes removed, and grease hauler names; grease haulers must take timestamped before/after photographs and maintain disposal records matching volumes pumped.

Regulating authorities must review and respond to grease control equipment designs within 60 days, and cannot require equipment retrofits or replacements unless FOG discharge exceeds allowable levels at least twice within a 30-day period.

Wastewater treatment plants that accepted septage disposal on or after January 1, 2023 must continue accepting septage from within their unit or neighboring units, with disputes subject to Indiana Department of Environmental Management determination and administrative review.
