Let's Get Real About MACT
Ask any environmental compliance engineer what their biggest worry is and they will likely mention something involving MACT (maximum achievable control technology) standards. As MACT standards come to cover more and more industries, many facilities have found achieving compliance to be a significant challenge. Frequently they find that under investment in air pollution control over a number of years substantially complicates their compliance. Some have held out for political change that they assumed would lead to a revocation of these standards. Although the MACT program is firmly established by law and not subject to any executive directives or revision like some other standards, they've built programs of minimal compliance assuming that MACT would be reversed. It hasn't. It's exceedingly unlikely that it will.
