Title 25—ENVIRONMENTAL PROTECTION DEPARTMENT OF ENVIRONMENTAL PROTECTION [ 25 PA. CODE CH. 16 ] Water Quality Toxics Management Strategy—State-ment of Policy [43 Pa.B. 4103]
[Saturday, July 20, 2013]The Department of Environmental Protection (Department) is amending Chapter 16 (relating to water quality toxics management strategy—statement of policy). These amendments complement the triennial review and revision of Chapter 93 (relating to water quality standards). See 43 Pa.B. 4080 (July 20, 2013) for the final-form rulemaking.
A. Effective Date
This final statement of policy will be effective on July 20, 2013.

C. Background and Summary
The Commonwealth's water quality standards in Chapters 16 and 93 and Chapter 92a (relating to National Pollutant Discharge Elimination System permitting, monitoring and compliance) implement sections 5 and 402 of The Clean Streams Law (35 P. S. §§ 691.5 and 691.402) and section 303 of the Federal Clean Water Act (33 U.S.C.A. § 1313). Water quality standards consist of the uses of the surface waters of the Commonwealth, the specific numeric and narrative criteria necessary to achieve and maintain those uses, and an antidegradation policy. Chapter 16 is a water quality policy for regulating toxic pollutants. It sets forth the guidelines for development of criteria for toxic substances and lists site-specific water quality criteria and analytical methods and detection limits for toxic substances. Chapter 16 is directly referenced as a supporting policy document in the Department's toxic substances regulations in §§ 93.8a and 93.8c (relating to toxic substances; and human health and aquatic life criteria for toxic substances).
The amendments update Chapter 16 to be consistent with the amendments to Chapter 93, as related to the Commonwealth's triennial review of water quality standards. The amendments also update and correct approved analytical methods in Tables 2A and 2B (relating to approved EPA and DEP accredited analytical methods and detection limits: inorganics; and approved EPA and DEP accredited analytical methods and detection limits: organics). The titles of these tables are also corrected to reflect that several analytical methods listed are Department accredited. This statement of policy may affect persons who discharge wastewater into surface waters of the Commonwealth or otherwise conduct activities which may impact these waters.
The Department discussed the triennial review with the Water Resources Advisory Committee (WRAC) five times in 2011, at the April, June, July October and December meetings. On January 11 2012, WRAC voted to have the Department present the rulemaking package to the Environmental Quality Board (EQB). The Agricultural Advisory Board declined the need for their consideration on the triennial review of water quality standards that was scheduled for their regular October 19, 2011, meeting.
The amendments were shared with the EQB as a companion to the triennial review of water quality standards rulemaking, although the EQB is not required to act on the revisions to the Department's statement of policy for toxic substances. The proposed statement of policy was published at 42 Pa.B. 4187 (July 7, 2012) with a 45-day public comment period that ended August 21, 2012. The Department held a public meeting and hearing for the purpose of accepting comments on the proposed statement of policy on August 8, 2012, in Conference Room 105, Rachel Carson State Office Building, 400 Market Street, Harrisburg, PA. The Department did not receive comments pertaining to the proposed statement of policy.
The draft final statement of policy was discussed with and approved by WRAC at its November 28, 2012, meeting. Comments received on the Chapter 93 rulemaking resulted in related changes to this final statement of policy. The changes to the proposed statement of policy are summarized in Section D.
D. Summary of the Change to the Proposed Amendment
Appendix A. Table 1A. Site-specific water quality criteria for toxic substances
1,4-Dioxane—Based on comments to the proposed amendments to Chapter 93 received by the EQB, the proposed Statewide criterion for 1,4-dioxane was withdrawn from this final statement of policy, but retained as a site-specific criterion (3 µg/L) in Table 1A.
A copy of the final amendments is available from the Division of Water Quality Standards at the address provided in Section B.

Acting Secretary(Editor's Note: Title 25 of the Pennsylvania Code is amended by amending a statement of policy in Chapter 16, Appendix A, Tables 1A, 2A and 2B to read as set forth in Annex A, with ellipses referring to the existing text of the tables.)
(Editor's Note: For a final-form rulemaking relating to this statement of policy, see 43 Pa.B. 4080 (July 20, 2013).
Fiscal Note: Fiscal Note 7-514 remains valid for the final adoption of the subject regulations.
Annex A TITLE 25. ENVIRONMENTAL PROTECTION PART I. DEPARTMENT OF ENVIRONMENTAL PROTECTION Subpart A. PRELIMINARY PROVISIONS ARTICLE II. STATEMENTS OF POLICY CHAPTER 16. WATER QUALITY TOXICS MANAGEMENT STRATEGY—STATEMENT OF POLICY APPENDIX A TABLE 1A
SITE-SPECIFIC WATER QUALITY CRITERIA FOR TOXIC SUBSTANCESThe following table contains water quality criteria that were developed based on a need for a site-specific water quality criterion, and according to the guidelines for criteria development, as contained in this chapter. The sources the Department of Environmental Protection (Department) uses to obtain relevant risk assessment values for these criteria include, but are not limited to, United States Environmental Protection Agency agency-wide supported data systems such as Integrated Risk Information System (IRIS) and ECOTOX; the Great Lakes' Tier II aquatic life criteria guidelines; and other Nationally developed criteria as reviewed and approved by the Department for Statewide use. A criterion placed in this table will remain a site-specific criterion as originally developed and be incorporated into the appropriate portion of §§ 93.9a—93.9z that relates to ''exceptions to specific criteria'' unless, during rulemaking, it is determined that the same criteria has general Statewide applicability.
