DEEP: 2013 Proposed Water Quality Standards Regulations

2013 Proposed Connecticut Water Quality Standards Regulations
The Water Quality Standards set the overall policy for management of surface water and ground water quality in accordance with the state and federal clean water programs.  They designate use goals, define allowable discharges, and identify measures necessary to maintain the chemical, physical, and biological integrity of Connecticut’s waters, provide for the protection and propagation of fish, shellfish, and wildlife, for recreation in and on the water, and to protect public and private drinking water supplies.

The established Water Quality Standards go through a public review process in accordance with state statute and federal law.  The most recent revision of the Standards was finalized February 25, 2011.

These regulations are being proposed by the Commissioner of the Department of Energy and Environmental Protection under the authority of section 22a-426 of the Connecticut General Statutes (CGS).  This section of the CGS was recently amended to require the promulgation of the state’s Water Quality Standards as regulations.  The proposed regulations codify the existing Standards into a regulatory format in fulfillment of the statute’s requirements.

Note: There are no substantive changes to the existing standards proposed as part of this rulemaking exercise. Substantive changes to the Water Quality Standards Regulations may be made as part of the formal triennial review process anticipated to begin in the Fall of 2013. The Department intends to solicit public comments on future changes to the Connecticut Water Quality Standards Regulations after completion of the proposed conversion to regulations. 

The proposed regulations will be known as the Connecticut Water Quality Standards Regulations.

The proposed regulations include, but are not limited to, provisions regarding: (1) short title and description; (2) purpose, goals and applicability; (3) definitions; (4) surface waters; (5) biological condition gradient model; (6) lake trophic categories; 7) ground waters; 8) antidegradation standards and antidegradation implementation policies; and 9) environmental criteria.
