Use this app to get snapshot of tank emissions
This company’s Tank Emissions app is available for iOS devices (including the iPhone and iPad). It allows users to estimate whether their systems are within permit limits, or if it is time for a qualified engineer to evaluate the tank and related system. Based on data from the U.S. Environmental Protection Agency’s AP 42 air pollutant emissions standard, the app simplifies a very complex set of calculations in order to give the user a rough estimate of the tank emissions. The results are not intended to be used officially; rather they provide guidance to help the user plan a path forward, says the company. — Halker Consulting, Englewood, Colo.
