Alternative systems (as defined in the Waste Treatment Handbook - Individual Household Systems), except fill systems which are permissible under § 136-10 below, may be permitted by application to the New York State Department of Health or, if applicable, the New York State Department of Environmental Conservation.
A. 
Only sewage may be discharged into the individual sewage disposal system. Surface and subsurface water, including roof, cellar, foundation and storm drainage, shall be excluded from such systems and shall be disposed of so that they will in no way affect the system.
B. 
No component of a leaching facility shall be located under driveways, roads, parking areas or areas subject to heavy loading, unless the same has been approved by a New York State licensed engineer and specifically designed for placement under driveways, roads, parking areas or areas subject to heavy loading. The foregoing shall not be interpreted to apply to absorption fields, which shall not be built under driveways, parts of buildings or swimming pools or areas subject to heavy loading. Surface waters shall be diverted from the vicinity of the system.
[Amended 6-17-1991 by L.L. No. 10-1991]
C. 
With reference to the one-hundred-foot minimum setback distance required between water bodies and a leaching facility, in no case shall any disposal field, seepage pit or other leaching facility be located closer than 100 feet from the mean high-water mark of any lake, pond, river or permanent or intermittent stream.
D. 
Water wastes known as "graywater" and discharged from dishwashers, laundry machines, sinks, bathtubs and showers shall not be permitted to be discharged into a separate leaching facility not meeting the standards for sanitary sewage discharges.
E. 
All septic tanks must be installed below finished grade of this site within a fifty-foot radius of the installation. This section is intended to prevent the occurrence of mounding in the area of the tank.
[Added 5-5-1997 by L.L. No. 4-1997; amended 7-6-1998 by L.L. No. 4-1998]

[1]
Editor's Note: Appendix F is included at the end of this chapter.
B. 
No sewage disposal fill or mound system may be located within 200 feet of the shorelines of Lake George. For the repair or replacement of existing systems, the distance may be a minimum of 100 feet.
C. 
No leaching facility will be permitted within 200 feet of the mean high-water mark of a lake, pond, river or permanent or intermittent stream if the percolation rate is zero to three minutes per inch. A system may be allowed within 200 feet of the shoreline if corrective measures are taken to reduce the percolation rate to a minimum of seven to 10 minutes per inch, provided that all other requirements of this Part 1 are met.

In those cases where tests for high groundwater determination and soil percolation as provided for in Appendix F[1] indicate that the quality and depth of natural soil is inadequate for an installation, a fill system may be utilized, provided that the following specifications are met. Final approval of fill systems shall not be granted until the fill is in place and the system evaluated according to the administrative provisions of this Part 1.
[1]
Editor's Note: Appendix F is included at the end of this chapter.
B.

(4) 
The soil used for fill shall be well-graded loamy sand or well-graded loamy sandy gravels and should contain a minimum of 12% of silts or clays containing no organic debris or no solid object larger than three inches in diameter, and the fill shall be allowed to stabilize naturally for at least 60 days.
(5) 
Sufficient fill must be installed to ensure a minimum of two feet between any trench bottom and maximum high seasonal groundwater, impervious material or bedrock. This separation must be three feet within 1,000 feet of Lake George.
(6) 
Only absorption fields shall be used as the leaching facility in fill systems.
(7) 
A channel or diversion system shall be placed about the fill system in the up-slope direction and of sufficient length to divert surface and sheet water runoff around the fill system.
(8) 
The top of fill over the leaching facility shall be crowned or sloped to allow natural surface runoff and shall be seeded.
(9) 
Side slopes of fill shall be graded to a slope not steeper than one vertical on three horizontal.
