This permit shall become voidable if the soils fail to adequately assimilate the wastes and may be - rescinded unless the facilities are installed, maintained, and operated in a manner which will protect the assigned water quality standards of the surface waters and ground waters. The ponding of wastewater on the surface of the distribution field when the dosing cycle commences shall be considered as evidence of failure of the soils to adequately assimilate the wastewater. Additionally, such failure shall be interpreted as a violation of this permit condition. 4. The residuals generated from these treatment facilities must be disposed in accordance with General Statute 143-215.1 and in a manner approved by the Division. 5. Adequate measures shall be taken to divert stormwater from the high rate infiltration area and to prevent wastewater runoff. 6. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited. 7. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface or ground waters resulting from the operation of this facility. The following buffers shall be maintained: a) 400 feet between high rate infiltration unit and any habitable residence or place of public assembly under separate ownership or which is to be sold, b) 200 feet between high rate infiltration unit and any private or public water supply source and any streams classified as WS or B, c) 200 feet from mean high water between high rate infiltration unit and any "SA" or "SB" classified surface waters, d) 200 feet from normal high water between high rate infiltration unit and any other stream, canal, marsh, or coastal waters, e) 200 feet from normal high water between high rate infiltration unit and any Class I or Class 11 impounded reservoir used as a source of drinking water, f) 200 feet between high rate infiltration unit and any other lake or impoundment, g) 200 feet between high rate infiltration unit and any Drainage systems (ditches, drains, surface water diversions, etc.) and from any groundwater lowering and surface drainage ditches, h) 100 feet between high rate infiltration unit and property lines, i) 50 feet between treatment units and property lines, and j) 50 feet between high rate infiltration unit and other treatment units and public right of ways. Some of the buffers specified above may not have been included in previous permits for this waste treatment and disposal system. These buffers are not intended to prohibit or prevent modifications, which are required by the Division, to improve performance of the existing treatment facility. These buffers do, however, apply to modifications of the treatment and disposal facilities which are for the purpose of increasing the flow that is tributary to the facility. These buffers do apply to any expansion or modification of the high rate infiltration areas and apply in instances in which the sale of property would cause any of the buffers now complied with, for the treatment and disposal facilities, to be violated. The applicant is advised that any modifications to the existing facilities will require a permit modification. A usable green area shall be maintained for wastewater disposal. The green area shall have the capability of accommodating the average daily flow of the facility being served without exceeding the Ioading rates of the green area.
