Existing incinerators which are not multiple chamber incinerators may be altered, modified or rebuilt as may be necessary to meet this requirement. The department may approve any other alteration or modification to an existing incinerator if such is found to be equally effective for the purpose of air pollution control as a modification or alteration which would result in a multiple chamber incinerator.
All new incinerators shall be multiple chamber incinerators, provided that the department shall approve any other kind of incinerator if it can be shown in advance of construction or installation that such other kind of incinerator is equally effective for purposes of air pollution control as an approved multiple chamber incinerator.
