Current through Register Vol. 40, No. 24, July 15, 2024
A.
				  This chapter is supplemental to 12VAC5-610 (Sewage Handling and Disposal
				  Regulations).
B. All procedures
				  pertaining to enforcement, minimum requirements for filing applications, and
				  processing of applications, including appeals and case decisions contained in
				  the Sewage Handling and Disposal Regulations shall apply to the permitting of
				  AOSSs under this chapter.
C. In any
				  case where there is a conflict between this chapter and the Sewage Handling and
				  Disposal Regulations, this chapter shall control.
D. This chapter supersedes Table 5.4 of the
				  Sewage Handling and Disposal Regulations for all AOSSs designed to disperse
				  TL-2 or TL-3 effluent. Table 5.4 of the Sewage Handling and Disposal
				  Regulations (12VAC5-610-950 ) shall govern the
				  design of any AOSS designed to disperse septic tank effluent to the soil
				  treatment area unless waived pursuant to
				  12VAC5-613-210.
E. All plans and specifications for AOSSs
				  shall be properly sealed by a professional engineer licensed in the
				  Commonwealth pursuant to Title 54.1 of the Code of Virginia unless such plans
				  are prepared pursuant to an exemption from the licensing requirements of Title
				  54.1 of the Code of Virginia. All AOSS designs prepared by a professional
				  engineer shall be reviewed by the department pursuant to § 32.1-163.6 of
				  the Code of Virginia unless otherwise designated in writing by the professional
				  engineer.
F. When AOSS designs are
				  prepared pursuant to an exemption from the licensing requirements of Title 54.1
				  of the Code of Virginia, the designer shall provide a certification statement
				  in a form approved by the division identifying the specific exemption under
				  which the plans and specifications were prepared and certifying that the
				  designer is authorized to prepare such plans pursuant to the
				  exemption.
G. Each application
				  under § 32.1-163.6 of the Code of Virginia shall include a site and soil
				  characterization report using the Field Book for Describing and Sampling Soils,
				  Version 2.0, National Soil Survey Center, Natural Resources Conservation
				  Service, U.S. Department of Agriculture, September 2002. The report may contain
				  such information that the designer deems appropriate; however, it must describe
				  the following minimum attributes of the site of the proposed soil treatment
				  area:
1. Depth to limiting features, seasonal
				  or perched water tables, pans, restrictions, or pervious or impervious
				  bedrock;
2. Slope of the project
				  area;
3. Ksat or percolation rate
				  at the proposed installation depth and at depths below the soil treatment area
				  to demonstrate compliance with this chapter. Ksat or percolation rate may be
				  estimated for small AOSSs. The Ksat or percolation rate must be measured using
				  an appropriate device for large AOSSs;
4. Landscape or landform; and
5. Project area along with those physical
				  features in the vicinity of the proposed AOSS normally associated with plans
				  for onsite sewage systems; such physical features include streams, bodies of
				  water, roads, utilities, wells and other drinking water sources, existing and
				  proposed structures, and property boundaries.
