The bill, known as General Assembly Committee Bill No. 575, aims to expand the bioscience enterprise corridor zone in Plainville, Connecticut. It proposes to amend subsection (b) of section 32-41s of the general statutes by repealing the existing language and substituting it with new provisions. The new language includes the designation of specific census tracts and blocks in Plainville, particularly identifying "fifty-three acres of property zoned Technology Park" as well as additional areas of raw land zoned Restricted Industrial. The bill also specifies that these areas will be eligible for the same benefits as businesses located in an enterprise zone, provided they meet certain conditions.

Key changes in the bill include the deletion of the previous designation of "fifty-three acres of property zoned Technology Park" and the block number "9000," which has been replaced with "2000." Additionally, the bill establishes that the areas in Plainville will be recognized as part of the bioscience corridor zone as of January 1, 2020. This expansion is intended to enhance the bioscience sector in the region and support eligible businesses within the newly defined zones.
