Section 310.104  State Law
a)         35 Ill. Adm. Code 307 includes three types of prohibitions and
pretreatment standards:

CFR 403.5 and more stringent prohibitions adopted by the Board (e.g., 35 Ill.
Adm. Code 307.1101);
2)         National pretreatment standards adopted by USEPA at 40 CFR 405
et seq., and incorporated by reference by the Board (e.g., Subparts F through

3)         More stringent concentration-based standards adopted by the
Board (e.g., 35 Ill. Adm. Code 307.1102 and 307.1103).
b)         For subcategories for which there are both categorical
pretreatment standards and concentration-based standards adopted by the Board
for a pollutant, the Control Authority must apply the standard that is more
stringent as applied to the particular discharge.
