State Emission Inventory Annual Reporting 

Annual emission inventories (EIs) cover actual emissions from the previous calendar year for permitted emission sources.  Emission inventory reporting is often a requirement for a majority of permitted facilities, but requirements may vary based on the state you are operating in and the permit you are operating under.  States use emission inventories to determine annual fees due to them.  Every three (3) years, states are also required to report emissions to the US EPA.   

 Unsure if you have any requirements for your facilities or how to use the reporting portal your state use? Let us know!  At Altamira, we have experience in EI reporting for states across the country.  We will look at what equipment you operate, what permits you currently operate under, and which states you operate in.  From there, we will prepare calculations for each facility and enter into the state’s specific reporting portal and help with submittal.  Every step is reviewed internally and will be available for you to review and approve as well before anything is submitted.   

 Reporting deadlines vary by state (as summarized below), but most are at the end of the end of the first quarter.  If your state isn’t listed below or if you have additional questions, contact us to get answers to your questions.
