The bill H. 4003 aims to amend the South Carolina Code of Laws regarding the Greater Greenville Sanitation District by significantly altering its authority and operations. It eliminates the district's ability to contract for sanitation services with third parties outside its geographic boundaries and restricts the commission to providing services only to single-family residential customers within the district. Additionally, the bill removes the commission's authority to charge property tax millage, allowing it to charge only a sanitation fee set by the county council. The commission is also required to retire all general obligation bonds and can only issue revenue bonds moving forward.

Furthermore, the bill stipulates that existing contracts will be exempt from these changes but cannot be renewed or extended beyond their current termination dates. The amendments are set to take effect on January 1, 2026, following approval by the Governor. This legislative change aims to streamline the operations of the Greater Greenville Sanitation District and ensure that its services are focused solely on residents within its boundaries.
