SC H4557

Adds Chapter 63 to Title 48 of the South Carolina Code to establish odor management regulations enforced by the Bureau of Air Quality of the Department of Environmental Services

Prohibits facilities from emitting "objectionable odors" beyond their property lines that are injurious to public health or unreasonably interfere with enjoyment of life or property use

Requires the Bureau to conduct site investigations when five or more verifiable odor complaints are submitted within 48 hours, including interviews, physical examinations, and testing with precision instruments

Mandates facility owners found in violation to submit an odor management plan within 90 days; failure to adequately reduce odors after plan revision can result in penalties up to $15,000 per day or permit revocation

Exempts on-farm agricultural operations, motor vehicles, municipal wastewater treatment plants, single-family dwellings, restaurants, refineries, and temporary activities from the regulations
