How South Carolina takes it
South Carolina files through E-Plan, which imports the Tier2 Submit file we build. The state requires E-Plan and takes no other method. Print and sign the E-Plan report and its confirmation email, and keep them at the site for at least five years.
The file we build is the one this state works from.
The filing is due 1 March each year and covers the calendar year before it. South Carolina is finished with you once you file — no copies, no e-mails, nothing else. Your local committee and fire department are separate: South Carolina says to ask them directly.
Before you send it — what else South Carolina asks for
South Carolina charges nothing at the state level, but the fee may not be zero for you — the state tells facilities to ask their county LEPC and local fire department about fees and about what those two want on top. That is the same pattern as Utah, where the county collects separately.
Does South Carolina set its own limits?
South Carolina's own agency says it uses the federal thresholds, and we read that page rather than assuming it. We have not gone behind it to the state code, so we say that too.
South Carolina applies the federal thresholds unchanged. The SERC requires E-Plan for the filing, and reports go to the SERC, the local emergency planning committee and the fire department by March 1.
The words we read
South Carolina Emergency Management Division, “EPCRA Requirements” and “Specific Requirements and Reporting in SC”: facilities storing “any substance for which a material safety data sheet (MSDS) is required by OSHA and in quantities exceeding the Threshold Planning Quantity (specified for Extremely Hazardous Substance or 10,000 pounds for all other substances)” must report to the state, the LEPC and the fire department. Checked against the South Carolina Code of Laws Title 48 chapter index: there is no “Hazardous Chemicals Right to Know” chapter — the 1991–92 bill of that name is not in the code — so South Carolina adds no statutory threshold of its own.

Where we read this
- South Carolina Department of Environmental Services, “Tier II” (des.sc.gov/programs/bureau-air-quality/tier-ii), read 2026-09-06: “South Carolina requires the use of E-Plan to satisfy the state’s Tier II reporting requirements”; reports are due March 1; “The state doesn’t charge Tier II reporting fees. Facilities should contact their County LEPC and local fire department for fees and specific reporting requirements for Tier II reporting.”SCEMD, “Specific Requirements and Reporting in South Carolina”, read 2026-09-08: “Facilities can enter information directly into E-Plan or import the Tier II Submit files (zip files or .t2s files) into the system.” It warns that “The E-Plan’s online Tier2 Reporting System will not allow facilities to submit their Tier II data until the Submission Validation Report indicate all required fields are correct and the Upload Data to E-Plan has been pressed,” and says South Carolina “strongly encourage[s] the use of E-Plan” rather than requiring it. That document still names SCDHEC throughout and never mentions the Department of Environmental Services, so it predates the 2024 reorganisation.E-Plan, User’s Guide, read 2026-09-07: “You can use the Import Tier2 function to import an existing Tier2 Submit export file (ZIP), Tier2 submission file (T2S), or CAMEO export file (ZIP) into your E-Plan account,” and its FAQ has a page for exactly that. So the file we build goes across instead of being retyped; you still complete the fields South Carolina adds and pass E-Plan’s validation before submitting.South Carolina DES, Tier II page (des.sc.gov/programs/bureau-air-quality/tier-ii), read 2026-10-12 through the Internet Archive snapshot dated 2026-01-13 because the live page refuses our requests with HTTP 403: “We require the use of E-Plan to satisfy the state’s Tier II reporting requirements… We no longer accept other reporting methods.” and “The facility should print the email and sign the Tier II report (PDF) from E-Plan and file them at the site for a minimum of five years.”Checked 2026-09-08
