25 Pa. Code § 95.2. Effluent standards for industrial wastes.

§ 95.2. Effluent standards for industrial wastes.

 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.
