Louisville Metro Air Pollution Control District (APCD) industrial construction permits are applications for a permit to build/install, modify, or replace equipment that emits or controls the emission of air pollutants.Permits ensure that emissions meet the needs of Louisville/Jefferson County to achieve and maintain federal air quality standards. Any piece of equipment or project that emits or controls air pollutants requires a permit prior to installation and operation unless it is specifically exempted from the APCD’s permit requirements. Companies apply for and receive a permit before purchasing new equipment to know exactly what the permit conditions and other requirements will be before construction, installation, and operation begin. Industrial construction permits are issued after a project demonstrates that compliance is achievable.Industrial construction permits include multiple types of emission based permits: Title V Permit, Federally Enforceable District-Origin Operating Permit (FEDOOP), and Minor Source permit, plus registrations (Registered Sources). FEDOOP permits are further divided into STAR-applicable and STAR-exempt. A source may also be identified as exempt from APCD permitting. Minor Source permits and Registered sources do not have construction permits.Title VTitle V refers to a section of the Clean Air Act (CAA) that addresses the largest sources of air pollution. Title V permits combine all the applicable federal, state, and local air requirements at a Title V facility into one permit.The Title V permit application process is detailed and complex and may require professional assistance. An opportunity for public comment and an opportunity for a public hearing are required. There is also a requirement that EPA and affected states are provided an opportunity to review proposed permits. EPA has the authority to object to permit issuance.Title V construction permits are issued for a period of 1 year. A complete Title V operating permit application must be submitted to the APCD prior to the end of the construction permit term. For an existing facility, this is a revision application to incorporate the changes from the construction permit into the operating permit.FEDOOPFEDOOPs, as described in APCD Regulation 2.17, are issued to major sources willing to accept federally enforceable emissions limitations below those that require a Title V permit. FEDOOPs are what the US EPA refers to as synthetic minor permits. FEDOOP sources that emit more than certain amounts of specific toxic air pollutants are subject to APCD’s Strategic Toxic Air Reductions (STAR) Program.FEDOOP construction permits are issued for a period of 1 year. A complete FEDOOP (operating permit) application must be submitted to the APCD between prior to the end of the construction permit term. For an existing facility, this is a revision application to incorporate the changes from the construction permit into the operating permit.Data Dictionary:Here is information about each column.
