This Subpart applies to all new, modified and existing infectious waste incineration facilities whose total permitted charging rate is less than 50 tons per day. Except for municipal waste incineration facilities existing as of the effective date of this Subpart [30 days after December 1, 1988], these requirements shall be effective and shall apply to all infectious waste incineration facilities for which a certificate to operate has been issued 90 days after such operating requirements have been formally promulgated pursuant to the State Administrative Procedure Act; provided, however, that where infectious waste incineration facilities are owned by health care facilities licensed pursuant to article 28 of the Public Health Law and in operation by permit of the department on or before September 1, 1987, then such standards shall become effective as to such facilities on January 1, 1992. Any new or modified infectious waste incineration facility whose total permitted charging rate is 50 tons per day or more or which accepts offsite municipal solid waste from a non-generator of infectious waste must also meet the requirements of Subpart 219-2 of this Part.
