(c) Except as provided in § 403.7, any new source subject to this subpart and producing titanium dioxide by the simultaneous beneficiation-chlorination (chloride-ilmenite) process which introduces pollutants into a publicly owned treatment works must comply with 40 CFR part 403 and achieve the following pretreatment standards for new sources (PSNS): Subpart V—Titanium Dioxide-Chloride-Ilmenite Process In cases where POTWs find it necessary to impose mass limitations, the following equivalent mass limitations are provided as an alternate: The limitations for Iron (T), Chromium (T), and Nickel (T) are the same as specified in § 415.225(c).
