EPA Cracks Down on Sulfuric Acid Producers: Cleaner Air for All
It is not often lately that I can applaud the actions of the Environmental Protection Agency. But today, it was announced that another agreement was reached between the EPA and three major manufacturers of sulfuric acid. The three companies — Chemtrade Logistics, Chemtrade Refinery Services, and Marsulex — will pay civil penalties for pollution emitted that violated the Clean Air Act in addition to the combined $12 million in new pollution controls that the companies will install to curtail harmful emissions of sulfur dioxide.
Remember sulfuric acid…it makes acid rain. We don’t hear as much about acid rain anymore, do we? A lot of that has to do with the Clean Air Act. And certain industries are better than others at cleaning up after themselves, but the acid production industry has not been held all that accountable until recently.
“The companies are expected to reduce harmful air pollution by an estimated 3,000 tons per year, which is well over half of their annual emissions,” said Granta Y. Nakayama, assistant administrator for EPA’s Office of Enforcement and Compliance Assurance. “Today’s settlement will improve air quality for millions of people.”
“This settlement is the product of our sustained effort to bring all sulfuric acid manufacturers into compliance with the Clean Air Act,” said Michael Guzman, Principal Deputy Assistant Attorney General for the Justice Department’s Environmental and Natural Resources Division. “We are pleased that the cooperative effort among us, our state counterparts, the Northern Arapaho Tribe, and the defendants resulted in this victory for the environment.”
Between January 2010 and January 2013, at its four production facilities in Beaumont , Texas ; Shreveport , La. ; Tulsa , Okla. ; and Riverton , Wyo. , Chemtrade will upgrade existing pollution control equipment called scrubbers to meet new, lower emission limits for sulfur dioxide. At its facility in Oregon , Ohio , Marsulex will improve chemical processing equipment, which will reduce sulfur dioxide emissions by no later than July 2011. Finally, Marsulex will install a new scrubber at Chemtrade’s sulfuric acid plant in Cairo , Ohio , to meet lower sulfur dioxide limits by July 2011. — EPA
Sulfuric acid production burns sulfur (or sulphur, if you prefer) to produce sulfur dioxide (SO2). SO2 readily combined with water to produce H2SO4, otherwise known as sulfuric acid. Concentrated sulfuric acid is used in many industries like fertilizers, steelmaking, ore refining, petroleum refining, and it’s even used in making nylon and detergents.
Making sulfuric acid is simple enough...
Reductions in sulfuric acid emissions will come from new scrubbers and lower allowance limits. The new short-term limits that the companies have agreed to finally follow are from 1.7 pounds to 2.5 pounds of SO2 per ton of product, according to the EPA.
The civil penalty comes from modifications made at Chemtrade and Marsulex that increased emissions, and since neither company bothered to gain proper permits to do so or the required scrubbers to limit those emissions, they effectively violated the Clean Air Act. The fines will go to the Federal government ($460,000) and the rest will go to the four states where the six manufacturing plants are located.
Good job, EPA, doing your, um, job?
