Saint-Gobain Containers, the US's second biggest glass bottle manufacturing firm, has been fined $140,000 (£78,869) for breaking federal air regulations.
In 2005, the firm paid almost one million dollars in fines after breaching air pollution regulations, one of the conditions being that they allocate around seven million dollars to control emissions.
However, the company's branch in Madera, California, was found to be in violation of this, as well as monitoring methods and the keeping of records during a routine inspection by the Environmental Protection Agency (EPA)
Deborah Jordan, Air Division director for the EPA's Pacific southwest area commented: "After the EPA concludes an enforcement action, our responsibilities don't end. Inspectors routinely return to ensure that facilities are in compliance".
The firm's headquarters are located in Muncie, Indiana and it has fourteen plants located throughout the US.
