Section 336.2013. Reference test method 5D.

Rule 1013. Reference test method 5D, testing of steel  manufacturing sources, reads as follows:

(a)        General description. Emission testing procedures shall follow the methodology specified in R 336.2004(1)(c) and (d) and  R   336.2012, unless otherwise provided in this rule.

(b)    Coke battery pushing emission control equipment outlet test procedure for scrubbers. Outlet emission tests for any scrubber emission control equipment controlling coke battery emissions shall be conducted as follows:

(ii)   Each sampling point shall be sampled for 1  cycle  operation,   which is defined as beginning when the coke guide and snorkels are engaged and continuing until the quench car leaves the hood.

(iii)    For a shed, the sampling period shall begin with the first movement of coke and shall end when the car enters the quench tower.

(iv)   Integrated gas samples shall be taken over the entire test period. The samples shall be analyzed for carbon monoxide, carbon  dioxide,  oxygen, and nitrogen by means of an Orsat analyzer. The sampling and sample analysis shall be performed in accordance with R  336.2004(1)(c).   The average  values from the 3 samples shall  be used in determining the  dry molecular   weight  of the exhaust gas. If a complete test  is not performed during the day, at least 1 sample shall be taken.

(v)   Based on design and previous data, saturated  conditions  shall  be assumed. The moisture content shall be calculated as per R 336.2004(1)(d), based on stack conditions during the preliminary and sampling traverses.
