EPA v. POLYNT COMPOSITES USA, INC - ACO

Case summary

Polynt owns and operates a facility in Sandusky, Ohio that conducts Miscellaneous Coating Manufacturing (MCM) operations including the manufacture of gel coats using styrene, methyl methacrylate, and other raw materials. At the Facility, Polynt operates mixers subject to the MCM NESHAP and Title V Permit conditions. Region 5 identified CAA violations through a March 20, 2023, inspection and an August 14, 2024, Section 114 information request. Polynt exceeded applicable Ohio SIP VOC limits, also found in the facility?s Title V Permit, and failed to demonstrate compliance with HAP limits. Polynt also violated MCM NESHAP requirements to set operating limits based on initial compliance conditions, conduct 5‑year performance tests, and meet recordkeeping, notification, and reporting duties. The ACO will require Polynt to: ? Reduce emissions of organic HAP by 75% considering both capture and control for process vessel vents via vent collection system modifications, lid replacements, and elimination of natural draft openings; ? Incorporate compliance measures into an operation maintenance plan; and ? Record and report the total source operating time. The compliance measures required by the proposed ACO are required by the Ohio SIP, MCM NESHAP, and Title V permit conditions.
