In order to qualify for the exemption the machinery and equipment must represent an addition to the assessment or grand list of the municipality in which the exemption is claimed and be directly attributable to and installed concurrently with the acquisition, construction, renovation or expansion established at the time the eligibility certificate is issued. Machinery and equipment existing in a manufacturing facility which has been acquired will also qualify for the exemption. Exempt machinery and equipment and the person responsible for paying taxes due with respect to the machinery and equipment will be stated in the eligibility certificate. Machinery and equipment installed in a manufacturing facility after an eligibility certificate is issued will also qualify for exemption from personal property taxation, but the exemption will not extend beyond the date the exemption of the manufacturing facility expires and will not apply unless the machinery and equipment is listed on the applicable replacement eligibility certificate together with the appropriate taxpayer. Any machinery and equipment installed in a building which has not been acquired, constructed, substantially renovated or expanded is not exempt from taxation under the program.
