§ 408.250 - Applicability; description of the Pacific Coast hand-shucked oyster processing subcategory.
The provisions of this subpart are applicable to discharges resulting from existing Pacific Coast handshucked oyster processing facilities which process more than 454 kg (1000 lbs) of product per day on any day during a calendar year and all new sources.
§ 408.251 - Specialized definitions.
For the purpose 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 product shall mean the weight of the oyster meat after shucking.
§ 408.252 - Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best practicable control technology currently available.
Except as provided in §§ 125.30 through 125.32, any existing point source subject to this subpart shall achieve the following effluent limitations representing the degree of effluent reduction attainable by the application of the best practicable control technology currently available (BPT):
Effluent characteristic | Effluent limitations | Maximum for any 1 day | Average of daily values for 30 consecutive days shall not exceed— | Metric units (kilograms per 1,000 kg of product) | TSS | 47 | 38 | Oil and grease | 2.4 | 1.8 | pH | ( 1) | ( 1) | English units (pounds per 1,000 lb of product) | TSS | 47 | 38 | Oil and grease | 2.4 | 1.8 | pH | ( 1) | ( 1) |

§ 408.254 - Pretreatment standards for existing sources.
Any existing source subject to this subpart that introduces process wastewater pollutants into a publicly owned treatment works must comply with 40 CFR part 403. In addition, the following pretreatment standard establishes the quantity or quality of pollutants or pollutant properties controlled by this section which may be discharged to a publicly owned treatment works by a point source subject to the provisions of this subpart.
Pollutant or pollutant property | Pretreatment standard | BOD | No limitation. | TSS | Do. | pH | Do. | Oil and grease | Do. |

§ 408.255 - Standards of performance for new sources.
The following standards of performance establish the quantity or quality of pollutants or pollutant properties, controlled by this section, which may be discharged by a new source subject to the provisions of this subpart:
Effluent characteristic | Effluent limitations | Maximum for any 1 day | Average of daily values for 30 consecutive days shall not exceed— | Metric units (kilograms per 1,000 kg of product) | TSS | 45 | 36 | Oil and grease | 2.2 | 1.7 | pH | ( 1) | ( 1) | English units (pounds per 1,000 lb of product) | TSS | 45 | 36 | Oil and grease | 2.2 | 1.7 | pH | ( 1) | ( 1) |

§ 408.257 - Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best conventional pollutant control technology.
Except as provided in §§ 125.30 through 125.32, the following limitations establish the quantity or quality of pollutants or pollutant properties, controlled by this section, which may be discharged by a point source subject to the provisions of this subpart after application of the best conventional pollutant control technology:
Effluent characteristic | Effluent limitations | Maximum for any 1 day | Average of daily values for thirty consecutive days shall not exceed— | Metric units (kilograms per 1,000 kg of product) | TSS | 45 | 36 | Oil and grease | 2.2 | 1.7 | pH | ( 1) | ( 1) | English units (pounds per 1,000 lb of product) | TSS | 45 | 36 | Oil and grease | 2.2 | 1.7 | pH | ( 1) | ( 1) |
