Emission Sources - Maximum Allowable Emission Rates

Permit Number 898

This table lists the maximum allowable emission rates and all sources of air contaminants on the applicant’s 

property covered by this permit. The emission rates shown are those derived from information submitted as 

part of the application for permit and are the maximum rates allowed for these facilities, sources, and related 

activities. Any proposed increase in emission rates may require an application for a modification of the 

facilities covered by this permit.

(4) Compliance with annual emission limits (tons per year) is based on a 12 month rolling period.

(5) Emission rate is an estimate and is enforceable through compliance with the applicable special condition(s) 

and permit application representations.

(6) The emission rates shown for Cr, Co, Ni, Si, Se, Ce, and Ti represent total combined emissions for both 

Furnace Nos. 1 and 2. The individual emissions rate from each stack can vary such that the sum of the 

emissions from the stacks of Melting Furnace Nos. 1 and 2 shall not exceed the total amount authorized.
