(Statutory authority: Public Health Law, §§ 1271, 1276)

[Filed 4/28/72. Effective 5/1/72.]

§213.1 Applicability

This Part shall apply to all ferrous jobbing foundry cupolas and ferrous jobbing foundry open hearths in operation on or prior to the effective date of this Part and to subsequent modifications but not to production foundries or any new foundries.

§213.2 Definitions

(a) Foundry cupola. A stack-type furnace used for melting of metals, consisting of, but not limited to, furnace proper, tuyeres, fans or blowers, tapping spout, charging equipment, gas cleaning devices and other auxiliaries.

(b) Foundry open hearth. A furnace in which the melting and refining of metal is accomplished by the application of heat to a saucer type or shallow hearth in an enclosed chamber. Such furnace consists of, but is not limited to, the furnace proper, checkers, flues and stack and may include a waste heat boiler, and oxygen lance and other auxiliaries pertinent to the process.

(c) Jobbing foundry. Any foundry where operations run intermittently for just long enough at one time to pour the molds that are ready on the foundry floor, job by job.

(d) Melt time. The time in which the metal is melting and available at the spout or tap hole, excluding any time the equipment is idle, preheating or preparing for shut down.

(e) Production foundry. Any foundry where operations will run continuously to pour a succession of molds that are constantly being prepared to receive the continuous flow of iron, or any foundry where the process weight will exceed 50,000 lb/hr, or any operation where melt times are in excess of four hours per 24-hour period.

§213.3 Prohibition

(a) After January 1, 1971, no person shall cause, permit or allow the emission of air contaminants, which will exceed the limits specified in table 1*, from any ferrous jobbing foundry cupola or ferrous jobbing foundry open hearth in operation on or prior to the effective date of this Part, this prohibition to be applicable, also, to modifications made after the effective date of this Part, to such a cupola or open hearth.

(b) The commissioner may modify the limits specified in table 1 [Appendix 4, infra], if in view of the properties of the emissions, isolated conditions, stack height and other factors, it can be clearly demonstrated that discharge of the contaminant or contaminants will not result in measurable or observable effects on receptors, nor add to an existing or predictable atmosphere burden of such contaminant or contaminants so that adverse effects would reasonably be expected therefrom.

(c) The provisions of this section shall not be construed to allow or permit any person to emit air contaminants in quantities which alone or in combination with other sources would contravene any established air quality standards. In such cases the commissioner may specify the degree of treatment required.

* Operations exceeding the permissible emission rate will be considered acceptable if the owner, operator or person responsible for the operation can show that under actual working conditions a collecting efficiency of 80% is achieved.
