Except as provided in 40 CFR 125.30 through 125.32, any existing point source subject to this subpart must achieve the following effluent limitations representing the degree of effluent reduction attainable by the application of the best conventional technology. (a) By-product cokemaking--iron and steel. Subpart A ------------------------------------------------------------------------ BCT effluent limitations ------------------------ Average of Pollutant or pollutant property daily Maximum values for for any 1 30 day consecutive days ------------------------------------------------------------------------ Kg/kkg (pounds per 1,000 lb) of product ------------------------ TSS............................................ 0.253 0.131 O&G............................................ 0.0327 0.0109 pH............................................. (\1\) (\1\) ------------------------------------------------------------------------ \1\ Within the range of 6.0 to 9.0. (1) Increased loadings, not to exceed 11 percent of the above limitations, are allowed for by-product coke plants which have wet desulfurization systems but only to the extent such systems generate an increased effluent volume. (2) Increased loadings, not to exceed 27 percent of the above limitations, are allowed for by-product coke plants which include indirect ammonia recovery systems but only to the extent that such systems generate an increased effluent volume. (b) By-product cokemaking--merchant.
