multiplied by the following factors to calculate the maximum for any one
day and maximum average of daily values for thirty consecutive days.

(3) See the comprehensive example in subpart D, Sec.
419.42(b)(3).
(c) The provisions of Sec. 419.12(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. Once-through cooling water may be discharged with a total
organic carbon concentration not to exceed 5 mg/l.
(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 practicable control technology currently available 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 and 110 mg/l total organic
carbon (TOC) 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 or 110 mg/l TOC 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:

\1\ In any case in which the applicant can demonstrate that the chloride
ion concentration in the effluent exceeds 1,000 mg/l (1,000 ppm), the
permitting authority may substitute TOC as a parameter in lieu of COD.
A TOC effluent limitation shall be based on effluent data from the
particular refinery which correlates TOC to BOD5. If in the judgment
of the permitting authority, adequate correlation data are not
available, the effluent limitations for TOC shall be established at a
ratio of 2.2 to 1 to the applicable effluent limitations for BOD5.
\2\ Within the range of 6.0 to 9.0.
