§ 63.11147 What are the standards and compliance requirements for existing sources not using batch copper converters?

(a) Emissions limits and work practice standards. (1) You must not discharge to the atmosphere through any combination of stacks or other vents captured process exhaust gases from the copper concentrate dryers, smelting vessels, converting vessels, matte drying and grinding plants, secondary gas systems, and anode refining department that contain particulate matter less than 10 microns in aerodynamic diameter (PM₁₀) in excess of 89.5 pounds per hour (lb/hr) on a 24-hour average basis.

(2) You must operate a capture system that collects the gases and fumes released during the transfer of molten materials from smelting vessels and converting vessels and conveys the collected gas stream to a control device.

(3) You must operate one or more capture systems that collect the gases and fumes released from each vessel used to refine blister copper, remelt anode copper, or remelt anode scrap and convey each collected gas stream to a control device. One control device may be used for multiple collected gas streams.

(b) Compliance requirements. For purposes of determining compliance with the emissions limit in paragraph (a)(1) of this section, you must comply with the requirements in paragraphs (b)(1) through (7) of this section.

(1) You must calibrate, maintain and operate a system to continuously measure emissions of particulate matter (PM) from the smelter's main stack.

(2) All PM collected by the smelter main stack continuous PM sampling system is reported as PM₁₀ unless you demonstrate to the satisfaction of the permitting authority that, due to an infrequent event, the measured PM contains a large fraction of particles greater than 10 microns in diameter.
