Many Twin Ports businesses are required to comply with federal and State regulations pertaining to dust control emissions. Some common emission points are at the loading or unloading of cargo from ships and trains. Companies such as CN depend on TPT to monitor and report their emissions in order to keep them in compliance of their permit. Occasionally, we may find our client is not in compliance. If this happens, TPT remediates ensuring our clients return to their required EPA or MPCA permitting requirements.
