Vapor Degreasing Process Uses Trichloroethylene (TCE) Replacement to Eliminate Hazardous Waste

Electro-Spec Inc. (Franklin, Indiana) had been using a trichloroethylene (TCE) solvent, one of these hazardous materials, in its Tiyoda vacuum vapor degreasing unit for years. When the solvent came up on the EPA list, environmental health and safety director Ben McKnight led a research project to find an alternative to this hazardous chemical. As members of an environmental stewardship program and members of a program sponsored by the Indiana Department of Environmental Management, Partners for Pollution Prevention, Electro-Spec needed to live up to its drive for environmental excellence, and therefore minimize or eliminate hazardous waste. The Production Machining magazine has a full article in the May 2019 issue detailing how good chemistry has helped this vapor degreasing process become greener.

Annual Compliance Certifications

In Indiana, regulated entities with Part 70 (Title 5) or federally enforceable state operating permits (FESOP) issued by IDEM’s Office of Air Quality (OAQ) are required to certify compliance through the submittal of Annual Compliance Certifications (ACC).

ACC submittal dates:

  • FESOP and Part 70 (Title 5) - for Clark, Elkhart, Floyd, Lake, Marion, Porter, St. Joseph, and Vanderburgh Counties, the ACC - due no later than April 15
  • FESOP and Part 70 (Title 5) - for all other counties - due no later than July 1

Much of the required information for the ACC comes from the permitted source’s quarterly deviation and compliance monitoring reports, permit conditions, inspection reports, and internal review practices. OAQ’s air inspectors are required to review all of the 1,100 plus certifications that are received or should have been received, and they must request resubmittals if errors are found within the reports.
