EPA v. CONCRETE SUPPLY COMPANY, LLC - CHARLOTTE, NC

Case summary

JUNE 29, 2026 - CONSENT AGREEMENT On May 30, 2019, EPA, in conjunction with NCDEQ, performed an Industrial Stormwater Enforcement Inspection (CSWEI) at the Facility to evaluate Respondent?s compliance with the requirements of Section 301 of the CWA, 33 U.S.C. ? 1311; the regulations promulgated thereunder at 40 C.F.R. ? 122.26; and the 2017 NC Permit. During the CSWEI of the Facility, EPA?s inspectors observed: A. The SWPPP provided during the CSWEI had not been updated to reflect the current conditions of the Facility per Parts III.1 and III.8 of the 2017 NC Permit. Specifically, the site map did not accurately depict the location of industrial activity areas, nor did the SWPPP address the removal of the retention pond, addition of the diversion berm on the north side of the site, or the operation and maintenance requirements for the recently installed CO₂ treatment system. B. The feasibility study included in the SWPPP failed to evaluate the option of minimizing the exposure of materials and processes to rainfall or diverting stormwater away from areas of potential contamination as required by Part III.2.a of the 2017 NC Permit. On August 14, 2019, the EPA issued an Inspection Report to Respondent. On January 8, 2020, EPA issued the Notice of Violation and an Opportunity to Show Cause to Respondent, pursuant to Section 309(a) of the CWA, 33 U.S.C. ? 1319(a). On April 20, 2020, the EPA held, and Respondent participated in, a show cause meeting via teleconference. On June 11, 2020, Respondent filed Response to EPA Notice of Violation and an Opportunity to Show Cause-South Plant (?CSC Response?) as a supplement to evidence presented at the Show Cause meeting. Respondent expressly denied certain findings and conclusions in the Notice of Violation and Opportunity to Show Cause issued by EPA. As part of the CSC Response, Respondent provided EPA with a copy of a SWPPP dated April 15, 2012 as the most current version of the Facility?s SWPPP. Respondent consents to the payment of a civil penalty, which was calculated in accordance with the Act, in the amount of $43,000, which is to be paid within thirty (30) calendar days of the Effective Date of the CAFO.
