Over the years, several errors and calculation mistakes have been discovered and corrected. Eventually, the USEPA elected to stop supporting the software. However, due to lacking an alternative, users had little choice but to use the EPA software to estimate air emissions and state agencies had little choice but to accept these

CFR Environmental was retained by a major natural gas pipeline operator to provide regulatory guidance and eliminate the risk of a potential major incident associated with pipeline leaks. A 42-mile section of a major natural gas pipeline was temporarily out-of-service for routine maintenance. Upon completion of the maintenance activities, the pipeline operator began pressurizing the pipeline by introducing gas. Employees were stationed at each valve location over the length

CFR Environmental has created a software solution using AP-42 that calculates air emissions from the storage of bulk organic liquids. The CF
