The software has been very helpful in gathering data from our plants to determine if we are meeting EPA requirements or not. It also helps us understand what changes need be made to increase efficiency of operations. I would like there to be more customization options available so that it can help with other processes as well. However, this is only an issue when you have multiple sites using CEMS. We use CEMS at two different locations (one large one and one smaller) to gather data about emissions during production. This allows us to ensure compliance is met by each site.
