CHAPTER I-ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
PART 419-PETROLEUM REFINING POINT SOURCE CATEGORY--Table of Contents
Subpart C-Petrochemical Subcategory
Sec. 419.34 Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best conventional pollutant
control technology (BCT).
(a) 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 conventional
pollutant control technology (BCT):
------------------------------------------------------------------------
BCT effluent limitations
--------------------------
Average of
daily values
Pollutant or pollutant property Maximum for for 30
any 1 day consecutive
days shall
not exceed
------------------------------------------------------------------------
Metric units (kilograms
per 1,000 m3 of
feedstock)
--------------
BOD5......................................... 34.6 18.4
TSS.......................................... 23.4 14.8
Oil and grease............................... 11.1 5.9

------------------------------------------------------------------------
\1\ Within the range of 6.0 to 9.0.
(b) The limits set forth in paragraph (a) of this section are to be
multiplied by the following factors to calculate the maximum for any one
day and maximum average of daily values for thirty consecutive days.
(1) Size factor.
------------------------------------------------------------------------
1,000 bbl of feedstock per stream day Size factor
------------------------------------------------------------------------
Less than 24.9............................................. 0.73
25.0 to 49.9............................................... 0.76
50.0 to 74.9............................................... 0.83

------------------------------------------------------------------------
(3) See the comprehensive example in subpart D, Sec.
419.42(b)(3).
(c) The provisions of Sec. 419.14(c) apply to discharges
of process wastewater pollutants attributable to ballast water by a
point source subject to the provisions of this subpart.
(d) The quantity and quality of pollutants or pollutant properties
controlled by this paragraph, attributable to once-through cooling
water, are excluded from the discharge allowed by paragraph (b) of this
section.
(e) Effluent limitations for contaminated runoff. The following
effluent limitations constitute the quantity and quality of pollutants
or pollutant properties controlled by this paragraph and attributable to
contaminated runoff which may be discharged after the application of the
best conventional pollutant control technology by a point source subject
to this subpart.
(1) If wastewater consists solely of contaminated runoff and is not
commingled or treated with process wastewater, it may be discharged if
it does not exceed 15 mg/l oil and grease based upon an analysis of any
single grab or composite sample.
(2) If contaminated runoff is commingled or treated with process
wastewater, or if wastewater consisting solely of contaminated runoff
which exceeds 15 mg/l oil and grease is not commingled or treated with
any other type of wastewater, the quantity of pollutants discharged
shall not exceed the quantity determined by multiplying the flow of
contaminated runoff as determined by the permit writer times the
concentrations listed in the following table:
