Revision of New York's Water Quality Standards Regulations
DEC is conducting its federally-mandated "triennial review" of the State's water quality standards, in which States are required to review their water quality standards every three years. DEC is in the pre-public proposal phase of this rule, and staff is considering a wide range of revisions/additions to water quality standards regulations, as outlined in the table below.
DEC will be completing a draft proposal over the next several months. Following that, we will conduct an assessment of the regulatory impact of the proposed changes. Once that is completed, and the proposal has undergone full internal review, it will be released for public comment. A public hearing to accept comments will be held, as will (contingent upon sufficient resources) a number of public information meetings around the State. Notification of the formal public process will be made via both the New York State Register and the Environmental Notice Bulletin.

(All regulatory citations below refer to Parts of 6 NYCRR)
|Add or revise definitions that support the water quality standards regulations.||700.1|
|Revise and expand language regarding the issuance of mixing zones for the discharge of treated wastewater (move some existing language from 700.2 to 702.16 and revise/expand).||700.2 and 702.16|

|Revise 701.13 to require that all or some Class I marine waters have water quality suitable for primary contact recreation (swimming) in order to meet the federal Clean Water Act (CWA) "swimmable" goal (currently met in many areas .||701.13|
|Change (as for Class I) to 701.14 for some Class SD marine waters; also require water quality for SD waters suitable for secondary contact recreation .||701.14|
|Clarify regulations (701.15 - 701.18) regarding the classification of fresh vs. saline groundwaters. Clarify/revise regulations (702.16) regarding groundwater effluent limitations for substances with guidance values.||701.15 - 701.18|
|Revise/update procedures for deriving water quality standards for human health and aquatic life, including for Health (Water Source) standards (702.2.4.and 5), Health (Fish Consumption (702.8), and Aquatic Life (702.9 and Part 706).||702.2, 702.4, 702.5, 702.8, 702.9, and 706|
|Review and as necessary, revise or add narrative standards in 703.2.||703.2|
|For Class I marine waters, revise Dissolved Oxygen (D.O.) standard to be the same as the existing D.O. standard for Classes SA, SB, and SC.||703.3|
|Add/Revise Pathogen Indicators for Recreational Waters to reflect 2012 EPA Recreational Water Quality Criteria.||703.4|
|Add/revise Standards for Class SA marine shellfishing waters (to be consistent with existing DEC regulations for the harvesting of shellfish, as set forth by the DEC's Division of Fish, Wildlife and Marine Resources).||703.4, relates to 6 NYCRR Part 47|
|Add/revise water quality standards for toxic substances to protect human health, aquatic life, and wildlife.||703.5 Table 1|
|Added provisions which are intended to address the overall consistency between standards and the assessment of water quality as provided for in the State's assessment methodology, including factors such as natural conditions/variability (a specific example is seasonally low D.O. in naturally stratified lakes including but not limited to Onondaga Lake).||703.1|
 US EPA has indicated all waters should support fishable/swimmable goals.
