This calculator is provided by OEMS (Occupational Exposure Management Systems) for general informational and educational purposes only. It is not professional environmental, engineering, or legal advice, and it does not replace an evaluation by a qualified environmental professional or a determination by the regulatory agency that has jurisdiction over your facility.
Results depend entirely on the information you enter and on the assumptions built into the tool. They may be incomplete, inaccurate, or not applicable to your facility. Emission factors, emission rates, and thresholds change over time. You are responsible for verifying all results against applicable federal, state, and local regulations (including EPA rules under the Clean Air Act, Clean Water Act, RCRA, and EPCRA), the conditions of your permits, current manufacturer and emission factor data, and your organization’s requirements before relying on them. State and local requirements may be more stringent than the federal rules used here.
Do not use this tool as the sole basis for permit applications, emissions inventories, regulatory reports or certifications, applicability or generator category determinations, containment design, or demonstrating compliance with permit or regulatory limits.
OEMS makes no warranties, express or implied, about the accuracy, completeness, or fitness for a particular purpose of this tool or its results. To the fullest extent permitted by law, OEMS is not liable for any loss, injury, damage, fine, or penalty arising from use of, or reliance on, this tool.
