Vertellus is the owner and operator of a specialty chemical manufacturing facility in Indianapolis, Indiana, which produces pyridine, pyridine derivatives, niacinamide (vitamin B-3), vinyl pyridine, picolines, picoline derivatives, and other specialty chemicals. These chemicals are used in industrial, pharmaceutical and agricultural applications. This settlement resolves the company's failure to comply with Section 112 of the CAA, the National Emission Standards for Organic Hazardous Air Pollutants for Equipment Leaks, at 40 C.F.R. Part 63, Subpart H, and the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Pharmaceutical Production, at 40 C.F.R. Part 63, Subpart GGG (known as the ?Pharma MACT?), as specified in the complaint filed with the consent decree in this matter. Vertellus has agreed to pay a civil penalty of $425,000 and perform a supplemental environmental project (SEP) for its violations of the CAA. Pursuant to the SEP, Vertellus will upgrade or, as necessary, replace 29 single seal pumps in organic hazardous air pollutant (HAP) service with a dual mechanical seal system, at an estimated cost of approximately $706,000. The decree includes an enhanced leak detection and repair (LDAR) program that Vertellus will implement at its Indianapolis facility to improve its compliance with LDAR requirements and to reduce HAP emissions at the facility. Vertellus has also installed a new incinerator, to comply with the requirements of the Pharma MACT.
