Many municipal and industrial wastewater discharge permits include extremely low final limits for metals such as copper, silver, or zinc. Meeting very low permit limits for metals such as copper and zinc can be difficult at best, and extremely expensive or not feasible at worst. At BTSolutions, we understand that obtaining approval for increased permitted final effluent metal limits can be a daunting task. We start with an evaluation of your monitoring data and determining the best EPA-approved procedure that will secure approval for an increased metal limit. Once we have evaluated your monitoring data, we utilize EPA-approved procedures such as the Water-Effect Ratio, the Biotic Ligand Model, the Recalculation Method, and Translator Calculation to provide all data needed to justify an increased metal limit. These procedures are designed to provide accurate and reliable data that regulatory agencies can use to make decisions about metal limits. Industrial and municipal wastewater facilities can expect to see an increase in permitted final effluent metal limits. The amount of increase varies significantly by site but increases of 2-6 times are not unusual.
