Section 309.101  Preamble

a)         Permits may be required under either of two subparts – NPDES Permits, Subpart A, which regulate discharges into navigable waters as defined in the CWA, or Other Permits, Subpart B, which regulate certain structures and discharges therefrom that are not required to have an NPDES Permit.

b)         Unless the contrary is clearly indicated, all references to "Parts" or "Sections" are to Ill. Adm. Code, Title 35:  Environmental Protection. For example, "Part 309" is 35 Ill. Adm. Code 309, and "Section 309.101" is 35 Ill. Adm. Code 309.101.
