A non-attainment NSR permit may be required for major sources of pollutants in nonattainment areas which meet certain other criteria. Emissions increases must be offset and controls must be installed which meet the lowest acheivable emission rates. In addition, several federal permitting programs have been delegated to the states. To determine the requirements in your state, take a look at the Liaise Environmental Links page which contains a link to your state's environmental agency. Facilities that produce air emissions above a certain level may require a state permit.
Requirements vary by state and location within the state.
Liaise State Permitting-Related Services Liaise will evaluate air emissions generating processes and equipment, including control equipment to identify and quantify emissions. EPA and state-approved calculation methods will be documented. Area maps, process flow diagrams and process descriptions will be included as required. Liaise will prepare the permit application forms and information as required by the appropriate state agency. If you're considering doing a State Permit Application, Amendment, or Renewal for your facility, Liaise would be happy to provide you with a free proposal.
