The DHEC 3559 form, known as the Notice of Intent (NOI) for the NPDES General Permit for Discharges Associated with Nonmetallic Mineral Mining Facilities, serves a critical role in the regulatory framework for mining operations in South Carolina. This form is essential for operators planning to discharge wastewater from nonmetallic mineral mining activities, including borrow pits. By submitting this form, operators formally notify the South Carolina Department of Health and Environmental Control (DHEC) of their intent to obtain coverage under the National Pollutant Discharge Elimination System (NPDES) permit. Key components of the DHEC 3559 include detailed site and operator information, descriptions of the materials to be mined, and specifics about the types of discharges expected from the site. Operators must also provide geographic coordinates, site maps, and any existing permit numbers to ensure compliance with environmental regulations. An annual operating fee of $100 is required, emphasizing the financial commitment associated with maintaining permit coverage. Ultimately, the DHEC 3559 form is not just a bureaucratic requirement; it is a vital tool for ensuring that mining operations are conducted responsibly, with due consideration for environmental protection and public health.
