Syz, Chief, Hater Resource Planner Agency of Environiental Conservation State Office Bldg, flontpelier 05602 802-244-6951 Fee: no Hailing List: no State Narrative Language For: Antidegradation General Policy - The Board (Venont Hater Resources Board) shall establish water quality classifications in accordance with the statutory provisions of the Act in a Banner consistent with Sections 1-02 and 1-03 of these rules. To the greatest extent possible the classification of the waters shall identify existing uses, background conditions, and the degree of water quality to be obtained and iaintained. Existing water quality classifications shall be maintained unless the Board, after public hearing, finds that they are contrary to the public interest except as provided for in 10 VSA 1253(f). Those waters whose quality wets or exceeds the water quality criteria specified in sections 3-01, 3-03, 3-05 and 3-06 of these rules and which quality lakes an important contribution to the propagation or survival of any beneficial species of aquatic biota at any period in their life history within any of the 17 planning basins identified in Chapter 4 of these rules, constitute high quality waters which have significant ecologic- al value and therefore are eligible for reclassification to Class A in accordance with the provisions of 10 VSA 1253(c) and 1253(f). The aquatic biota shall be considered to have been significantly altered whenever a discharge or combination of discharges results in a change in the number and diversity of aquatic biota that exceeds the range of natural variation within the receiving waters where such a change results in a measurable alteration of the essential biological characteristics of the receiving waters. The natural variation of aquatic biota shall be detenined by saipling and statistical protocols established by the Secretary as provided for in section 2-01 (f) of these rules. Please refer to the 'EPA Hater Quality Criteria Sumaaries; A Compilation of State/Federal Criteria' for additional antidegradation language for Veriont. State Narrative Language For: Toxics The waters of the state shall be tanaged so as to prevent the discharge of radioactive or toxic wastes in concentrations, quantities or coibinations that may create a significant likelihood of an adverse impact on hutan health or acute or chronic toxicity to aquatic biota, fish or wildlife. Unless otherwise specified by these rules, the Secretary shall deteraine liiits for discharges containing radioactive or toxic wastes based on the results of biological toxicity assessments and the appropriate available scientific data, including but not lieited to: 1. The current edition of the EPA publications "Quality Criteria for Hater1 and the 1980 Ambient Hater Quality Criteria Documents ("Unite Books") 2. The Vernont State Health Regulation, Part 5, Chapter 3 'Radiological Health", effective as of 12/10/77 3. 10 CFR 50, Appendix I In establishing such limits the Secretary shall give consideration to the potential for bioaccumulation as well as any antagonistic or synergistic relationship that may exist between the wastes being discharged and the concentration of other wastes or constituents in the receiving waters. The discharge of radioactive wastes shall not exceed the lowest limits which are reasonably achievable. State Narrative Language For: Free From VT-1 ------- VERMONT Nutrients - No increase which would accelerate eutrophication or result in concentrations that may stimulate the growth of aquatic plants, fungi, or bacteria, in a manner which has an undue adverse effect on any beneficial values or uses. flquatic habitat - No change froi background conditions which would have an undue adverse effect on the composition of the aquatic biota, the physical or cheiical nature of the substrate or the species coiposition or propagation of fishes. Sludge deposits or solid refuse - None Settleable solids, floating solids, oil, grease, scut, or total susoended solids - None in such concentra- tions or coibinations which would have an undue adverse effect on any beneficial values or uses. State Narrative Language For: Low Flow Unregulated Haters - The applicable water quality criteria shall apply at all times except when the average daily flow is less than the seven day low flow, ten year return period (7810). This rule shall not be construed to allow less than the normal design operation of any wastewater treatment facility during periods of low stream flow or to otherwise waive the terts of any permit issued under the Act. Regulated Haters - The applicable water quality criteria shall apply at the agreed liniiui flow, or 7Q10, whichever is less. In the absence of such an agreement, the water quality criteria shall apply at the absolute low flow resulting from regulation, or 7Q10, whichever is less. State Narrative Language For: Mixing Zones (A) Designation - Mixing zones shall not be created in any Class A water. In all other waters, the Secretary may, in conjunction with the issuance of a permit, designate a specific portion of the receiving waters not exceeding 200 feet frot the point of discharge as a mixing zone for any waste which has been properly treated to comply with all applicable state and federal treatient requirements and effluent limitations. Hithin any nixing zone the Secretary may, in accordance with the terts of a pertit, waive the provisions of sections 1-03, 3-01, 3-03(B), and 3-04(B) provided that the quality of the waters downstream of the mixing zone conplies with all applicable provisions of these rules. (B) Mixing Zone Criteria - The Secretary shall insure that conditions within any mixing zone shalls 1. Not create a public health hazard, and 2. Not constitute a barrier to the passage or migration of fish or result in an undue adverse effect of fish, aquatic biota or wildlife, and 3. Not interfere with any existing use of the waters. VT-2 ------- VERMONT » Classifications: Class fl Haters with a very high level of Mater quality which is coipatible with the following beneficial values and uses: 1) Values - High quality waters which have significant ecological value and water quality of a unifonly excellent cha racter. 2) Uses - As a source of public water supply with disinfection when necessary and, when coipatible, for the enjoyient of water in its natural condition. Class B Caters with a high level of quality, which is coipatible with the following beneficial values and uses: 1) Values - Hater which is of a quality which consistently exhibits good aesthetic value and provides high quality habitat for aquatic biota, fish and wildlife. 2) Uses - Public water supply with filtration and disinfection; irrigation and other agricultural uses; swiuing, and recreation. . Class c Haters with a good level of quality which is compatible with the following ' beneficial vaules and uses: 1) Values - Habitat suitable for aquatic biota, fish and wildlife. 2) Uses - Recreational boating and any recreational or other water uses in which contact with the water is tiniial and where ingestion of the water is not probable; irrigation of crops not used for huian consuiption without-cooking; and coipatible industrial uses. Fish Habitat To provide for the protection and tanageient of fisheries, the waters of the Designation State are designated in Appendix A of the Venont Hater Quality Standards as being either a cold or wart water fish habitat. Hhere appropriate, such designations §ay be seasonal.
