The proposed bill H. 4557 aims to establish a comprehensive framework for odor management in South Carolina by adding Chapter 63 to Title 48 of the South Carolina Code of Laws. It defines key terms related to odor complaints and outlines a process for investigating verifiable complaints. The Bureau of Air Quality is tasked with conducting investigations when five or more complaints are received within a 48-hour period. If an odor is deemed objectionable, the facility owner must develop and submit an odor management plan within 90 days, with the possibility of a 90-day extension for good cause. The bill also stipulates that penalties may be imposed for non-compliance, including fines of up to $15,000 per day or modifications to the facility's operating permit.

Certain exemptions are included in the bill, which specifies that it does not apply to on-farm animal and agricultural operations, motor vehicles, municipal wastewater treatment plants, single-family dwellings, and other specified activities. Additionally, the Bureau of Air Quality is authorized to promulgate regulations to implement the chapter, including establishing odor standards and procedures for addressing complaints. The bill is currently under consideration in the House Committee on Agriculture, Natural Resources, and Environmental Affairs.
