My facility has a wastewater evaporator. Do I need to show compliance with Env-A 1400?
Yes. You will need to make sure that the emissions from the evaporator are in compliance with Env-A 1400. However, it is important to remember that compliance with Env-A 1400 only applies to RTAPs that can be emitted into the outdoor air. RTAPs that are not volatile (including most metals) and are retained in the wastewater are not emitted, and will therefore be in compliance with Env-A 1400. On the other hand, any volatile RTAPs (e.g., solvents) in the wastewater can be emitted by an evaporator into the outdoor air. As a result, compliance with Env?A 1400 for these RTAPs must be demonstrated, and appropriate documentation of compliance must be retained on site. All wastewater evaporators, regardless of their compliance status with the NH Air Toxics Control Program, must determine their need for a Limited Permit under the Hazardous Waste rules.
