Section 22a-209-7 - Solid waste disposal areas

Solid waste disposal areas shall comply with the following permit and operating requirements.

(a) Any person wishing to operate a solid waste disposal area must comply with the permit requirements of Section 22a-209-4 of these regulations.

(b) The information which the Commissioner requires in an application may vary according to the category of the disposal area. Such categories may include:

(1) existing solid waste disposal areas where future disposal will take place only in areas where solid waste has previously been disposed of and is still present,

(2) existing solid waste disposal areas where future disposal will take place in areas where no solid waste had previously been disposed of, or, if solid waste had previously been disposed of, it has been removed, and

(3) new solid waste disposal areas.

(c)Protection of ground and surface waters.

(1) Minimum separation from ground waters. A minimum of sixty (60) inches shall be maintained between the base of deposited solid wastes and the maximum high water table or bedrock unless the permittee can establish to the satisfaction of the Commissioner that some lesser separation will be adequate to insure that solid wastes do not contact ground water. This provision shall not apply to solid waste disposal areas subject to solid waste permits granted prior to the effective date of these regulations which expressly authorize a minimum separation from ground water or bedrock of less than sixty (60) inches, provided that the permittee establishes to the satisfaction of the Commissioner that the continuation of solid waste disposal in accordance with such existing permit will not result in contact of solid waste with ground water.

(2) Water quality.

(A) In addition to the requirement of 22a-209-7 (c) (1) above, and except as provided in 22a-209-7 (c) (2) (B) below, a new or existing solid waste disposal area shall not impair the quality of surface or ground water beyond the solid waste boundary to a degree that would degrade the quality of such waters beyond the water quality classification established by the Department in accordance with Section 22a-426 of the Connecticut General Statutes, The Connecticut Water Quality Standards and Criteria, as amended, or the standards for quality of public drinking water established by the State Department of Health Services and contained in Section 19-13-B102 of the Regulations of Connecticut State Agencies, as amended. In those cases where the existing water quality fails to meet the established standards, the disposal area shall not further degrade the water quality.

(B) Notwithstanding 22a-209-7 (c) (2) (A) above, the Commissioner may designate an alternate boundary, beyond the solid waste boundary, beyond which the site may not impair the quality of surface or ground waters in accordance with the standards noted in 22a-209-7 (c) (2) (A). The designation of an alternate boundary must not result in the degradation of the quality of water which may be needed or used for human consumption, and must be based on an analysis to include but not be limited to the following factors:

(i) the hydrogeological characteristics of the facility and the surrounding land,

(ii) the volume and physical and chemical characteristics of the leachate,

(iii) the quantity, quality and directions of flow of ground water,

(iv) the proximity and withdrawal rates of ground water users in the vicinity of the solid waste disposal area,

(v) the availability of alternate drinking water supplies,

(vi) the existing quality of ground water including other sources of contamination and their cumulative impacts on ground water,

(vii) public health, safety, and welfare effects, and

(viii) the zone of impact for the leachate plume.

(3) Grading. The solid waste disposal area shall be graded, and provided with drainage facilities if necessary, to minimize infiltration of rainfall or surface runoff onto the area, to prevent erosion or washing out of the area, and to prevent the collection of standing water on the area. The top surface area shall at all times be graded to a slope of at least four (4) percent unless otherwise authorized by the Commissioner, and the side slopes shall not exceed a grade of one (1) on three (3), one vertical on three horizontal, unless otherwise authorized by the Commissioner.

(4) Floodplains. Solid waste facilities in floodplains shall not restrict the flow of the base flood, reduce the temporary water storage capacity of the floodplain, or result in washout of solid waste, so as to pose a hazard to persons or property, wildlife, or land or water resources.

(5) Surface water. Solid waste shall not be deposited so as to come in contact with surface waters, and disposal operations shall be conducted so as to minimize impact on surface waters. The Commissioner shall determine the required separation distance between deposited solid wastes and surface water for each solid waste disposal area based on site conditions.

(6) Erosion control. Siltation or retention basins or other methods approved by the Commissioner for retarding runoff shall be used where necessary to avoid stream siltation or flooding problems due to excess runoff.

(7) Wells. A minimum distance of one thousand (1000) feet shall be maintained between deposited solid wastes and wells used for water supply purposes unless the owner or operator can establish to the satisfaction of the Commissioner that some lesser separation will be adequate to insure against pollution of the waters withdrawn from said wells.

(8) Monitoring.

(A) No new solid waste disposal area shall begin operations without the owner or operator first installing a ground water monitoring system constructed and located as specified in the approved facility plan. Further, no new disposal area shall begin operations prior to the owner or operator obtaining a sufficient number of surface and ground water samples, and analyses thereof, to establish baseline water quality information. Monitoring shall be performed in accordance with the schedule in the facility plan and/or permit to construct.

(B) Upon written notice to the owner or operator of an active solid waste disposal area or the owner of an inactive or closed solid waste disposal area that in the opinion of the Commissioner the area poses an actual or potential threat to the quality of the ground or surface waters of the state, the owner or operator shall investigate the extent and degree of surface and/or ground water contamination resulting from the disposal of solid wastes; submit construction and installation plans for a surface and/or ground water monitoring system to the Commissioner for approval; and, upon approval, install such monitoring system in conformance with such approved plans. The approved plans shall become part of the facility plan. Monitoring shall be performed in accordance with a schedule approved by the Commissioner.

(C) Ground or surface water samples shall be analyzed by a state-approved laboratory using methods approved by the Commissioner. Copies of analyses shall be forwarded to the Solid Waste Management Unit of the Department.

(d)Access.

(1) All-weather roads which provide access between public roads or highways and the solid waste disposal area are required and shall be maintained so as to be passable by all vehicles which utilize the area.

(2) Access to the solid waste disposal area shall be controlled to prevent unauthorized use. Control may be accomplished through use of appropriate fences, gates and signs.

(3) A sign shall be posted at the entrance to the facility which states, at a minimum, the name of the permittee and hours of use of the area, the authorized users, and required safety precautions.

(e)Fire protection.

(1) The owner or operator of an active solid waste disposal area, and the owner of an inactive or closed disposal area shall be responsible for firefighting activities. The owner or operator of a disposal area wherein smoldering, smoking or burning is occurring shall:

(A) immediately notify the Solid Waste Management Unit of the Department,

(B) if reasonably necessary, obtain firefighting assistance from the fire department(s) having jurisdiction in the area,

(C) insure that firefighting activities continue until all smoldering, smoking and burning has ceased, as proven by scientific methods acceptable to the Department, and

(D) close the facility until all smoldering, smoking and burning has ceased, if required by the Commissioner or local firefighting officials.

(2) The owner or operator of any solid waste disposal area shall not conduct disposal activities within the immediate vicinity of any smoldering, smoking, or burning. Precautions shall be taken to prevent disposal activities from interfering with firefighting activities.

(3) Any disruption of the grade or covered compacted surfaces shall be repaired and recovered upon completion of firefighting activities.

(f)Measuring procedures.

(1) Daily records for regional solid waste disposal areas shall be maintained in a manner acceptable to the Commissioner. Such records shall state measured weights or estimated tonnage of wastes received from each municipality using the site, total weights from other sources, and the tonnage of materials removed for resource recovery and the markets used. Such records shall be available for inspection by representatives of the Department at any reasonable time. Monthly summaries of these records shall be submitted to the Department no later than ten (10) days after the last day of each quarter of the calendar year.

(2) Updated topographic mapping of fill areas performed in compliance with the specifications in 22a-209-4 (b) (2) (A) (ii) and (iii) shall be submitted to the Commissioner annually, for regional solid waste disposal areas. The Commissioner may require the submittal of such information for other disposal areas as he or she deems necessary.
