Exemption Administration Manual—Part 2: Industrial, Commercial, and Public Service
Section 4.06 - RPTL Section 477: Industrial Waste Treatment Facilities
Year originally enacted:
This exemption applies to an improvement used as an industrial waste treatment facility constructed or improved after May 12, 1965 in order to comply with the Environmental Conservation Law. Industrial waste treatment facilities are partially exempt from taxation and special ad valorem levies. No exemption from special assessments is allowed. The amount of exemption is limited to the increase in value of the property attributable to the construction or improvement of the facility.
Property location requirements:
Property use requirements:
Improvements must be used for the treatment, neutralization, or stabilization of industrial waste from a point immediately preceding the treatment to the point of disposal, including the necessary pumping and transmitting facilities but excluding facilities installed for the primary purpose of salvaging materials which are usable in the manufacturing process or are marketable.
Certification by state or local government:
A certificate of compliance must be issued by the State Commissioner of Environmental Conservation pursuant to ECL §17-0705 and must accompany the required exemption application form (RP-477).
Where only a temporary certificate has been issued for a facility which is incomplete on the appropriate taxable status date, the exemption applies only to taxes levied for that particular taxable status date and a new application must be filed in the next succeeding year. Facilities which are exempt on the basis of a permanent certificate of compliance continue to be exempt from year to year unless the certificate is revoked by the State Department of Environmental Conservation.
Required construction start date or other time requirement:
Improvements must have been constructed after May 12, 1965.
