This subpart applies to discharges to waters of the United States and introduction of pollutants into publicly owned treatment works resulting from the production of chrome pigments.
For the purposes of this subpart:
(a) Except as provided below, the general definitions, abbreviations and methods of analysis set forth in part 401 of this chapter shall apply to this subpart.
(b) The term chrome pigments means chrome yellow, chrome orange, molybdate chrome orange, anhydrous and hydrous chromium oxide, chrome green, and zinc yellow.
(c) The term product means chrome pigments.
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 practicable control technology currently available (BPT):
Subpart AH—Chrome Pigments

| Maximum for any 1 day
| Average of daily values for 30 consecutive days

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 available technology economically achievable (BAT): The limitations for Chromium(T), Lead(T), and Zinc(T) are the same as specified in § 415.342.
(a) Existing sources which annually introduce less than 210,000 cubic meters per year (55 million gallons per year) of chrome pigments process wastewater into a publicly owned treatment works are subject only to the standards specified in 40 CFR part 403.
(b) Except as provided in 40 CFR 403.7 and 403.13 and paragraph (a) of this section, any existing source subject to this subpart which introduces pollutants into a publicly owned treatment works must comply with 40 CFR part 403 and achieve the following pretreatment standards for existing sources (PSES):
Subpart AH—Chrome Pigments
| Pollutant or pollutant property
| PSES effluent limitations
|
|---|
| Maximum for any 1 day
| Average of daily values for 30 consecutive days
|
|---|
| Milligrams per liter (mg/l)
|
| Chromium (T) | 2.9 | 1.2
|
| Lead (T) | 3.4 | 1.4
|
| Zinc (T) | 2.9 | 1.2 |
Any new source subject to this subpart must achieve the following new source performance standards (NSPS): The limitations are the same as specified in § 415.342.
Except as provided in 40 CFR 403.7, any new source subject to this subpart 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): The limitations are the same as specified in § 415.344.
