Current through Register Vol. 55, No. 13, March 29, 2025
Industrial wastes must meet the following effluent
standards:
(1) Wastes must have a pH
of not less than 6 and not greater than 9, except where:
(i) The wastes are discharged to an acid
stream, in which case the pH may be greater than 9.
(ii) The discharger affirmatively
demonstrates, in writing, to the Department that biological respiration in the
wastewater treatment system will cause the discharge to exceed the limits in
this paragraph and that exceeding these limits will not result in a violation
of applicable water quality standards or of the applicable treatment
requirements and effluent limitations to which a discharge is subject under the
Federal Act, in which case the Department may grant a variance, in writing,
from the limitation set forth in this paragraph.
(2) Oil-bearing wastewaters, except those
subject to paragraph (3), must comply with the following:
(i) At no time cause a film or sheen upon or
discoloration of the waters of this Commonwealth or adjoining
shoreline.
(ii) At no time contain
more than 15 milligrams of oil per liter as a daily average value nor more than
30 milligrams of oil per liter at any time, or whatever lesser amount the
Department may specify for a given discharge or type of discharge as being
necessary for the proper protection of the public interest or to meet any
requirements based upon the State Act or the Federal Act, as defined in §
92.1 (relating to definitions).
(3) Petroleum marketing terminals must:
(i) Be provided with facilities to remove oil
from waters, including stormwater runoff, before discharge into waters of this
Commonwealth. Compliance with this paragraph constitutes compliance with
paragraph (2)(i) except to the extent that the State Act or Federal Act or
regulations promulgated thereunder impose a more stringent
requirement.
(ii) Develop,
implement and keep up to date pollution incident prevention plans as described
in §
91.34 (relating to activities
utilizing pollutants).
(iii)
Design, maintain and utilize oil removal facilities that consist of an American
Petroleum Institute (A.P.I.) listed oil separator, unless the person operating
the facility can demonstrate to the Department that an alternate design is
equivalent or better in removing oil from water to maintain and protect the
waters of this Commonwealth, including all existing and designated uses
established under Chapter 93 (relating to water quality
standards).
(4) Waste may
not contain more than 7 milligrams per liter of dissolved iron.
(5) When surface waters are used in the
industrial plant, the quality of the effluent need not exceed the quality of
the raw water supply if the source or supply would normally drain to the point
of effluent discharge, unless otherwise required under the act or Federal Act
or regulations promulgated thereunder.
