Approval and Promulgation of Implementation Plans; Indiana

The EPA is approving nine negative declarations submitted by the State of Indiana on November 8, 1999, and January 10, 2000. Each of these negative declarations concerns sources located in Lake and Porter Counties, which are classified as a severe nonattainment area for the pollutant ozone. Each of the negative declarations indicates that the State has searched its emissions source inventory and permit files for Lake and Porter Counties and determined there are no sources with a potential to emit 25 tons per year or more of volatile organic compounds (VOC) in the following source categories: aerospace coating operations, industrial clean up solvents, industrial wastewater processes, offset lithographic operations, business plastics, automotive plastics, and synthetic organic chemical manufacturing industries (SOCMI) batch processes, reactors and distillation units.
