§415.340   Applicability; description of the chrome pigments production subcategory.

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.

§415.341   Specialized definitions.

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.

§415.342   Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best practicable control technology currently available (BPT).

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

Pollutant or pollutant propertyBPT effluent limitations
Maximum for any 1 dayAverage of daily values for 30 consecutive days
Kg/kkg (or pounds per 1,000 lb) of product
TSS9.13.8
Chromium (T)0.310.13
Lead (T)0.360.15
Zinc (T)0.310.13

1Within the range 6.0 to 9.0.

§415.343   Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best available technology economically achievable (BAT).

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.

§415.344   Pretreatment standards for existing sources (PSES).

(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 propertyPSES effluent limitations
Maximum for any 1 dayAverage of daily values for 30 consecutive days

Chromium (T)2.91.2
Lead (T)3.41.4
Zinc (T)2.91.2

In cases where POTWs find it necessary to impose mass limitations, the following equivalent mass limitations are provided as an alternate: The limitations for Chromium(T), Lead(T), and Zinc(T) are the same as specified in §415.342

§415.345   New source performance standards (NSPS).

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.

§415.346   Pretreatment standards for new sources (PSNS).

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.
