Section 310.104  State Law

a)         35 Ill. Adm. Code 307 includes three types of prohibitions and

pretreatment standards:

1)         Prohibitions, including prohibitions adopted by USEPA at 40

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

CT of 35 Ill. Adm. Code 307); and

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.
