Current through Register Vol. 40, No. 24, July 15, 2024
A. An elevated
					 sand mound is a soil absorption system that incorporates low pressure
					 distribution and sand filtration to produce treated sewage prior to absorption
					 in the natural underlying soil. The elevated sand mound utilizes less gross
					 soil area than most other soil absorption systems. Elevated sand mounds differ
					 from pads in that elevated sand mounds are always an aboveground system, may
					 receive septic tank effluent, and always require pressure distribution, and the
					 infiltrative surface follows the natural ground surface and contour of the
					 site.
B. Mound systems receiving
					 septic tank effluent shall be designed and constructed in accordance with the
					 Wisconsin Mound Soil Absorption System Siting, Design and Construction Manual
					 prepared by the Small Scale Waste Management Project, School of Natural
					 Resources, College of Agricultural and Life Sciences, University of
					 Wisconsin-Madison dated January 2000. Drip dispersal or low pressure
					 distribution shall be used.
C. The
					 manual referred to in subsection B of this section shall be used for the
					 designated construction of elevated sand mounds. The following criteria are
					 required for all elevated sand mound systems in addition to the requirements
					 found in the manual.
1. The proposed mound
					 site shall be fenced, roped, or otherwise secured, and marked, to prevent
					 damage by vehicular traffic. Activities on the mound site shall be severely
					 limited in order to protect it to the greatest extent possible.
2. The mound must be constructed during dry
					 weather and soil conditions.
3.
					 Wooded sites shall not be used unless it is shown by the applicant that the
					 wooded site is the only site available, and if the applicant can demonstrate
					 that the site can be properly prepared. If a wooded site is used, trees shall
					 be removed by cutting them off at ground level, leaving the stumps in place.
					 The cut trees shall be removed using methods that do not require driving
					 equipment over the mound site and that do not result in the removal of any soil
					 from the site. Larger basal areas may be required on wooded sites.
4. When the depth to a restriction,
					 shrink-swell soils, or a water table is less than 24 inches, pretreatment
					 sufficient to produce TL-2 effluent or TL-3 effluent may be used to reduce
					 these distances. in accordance with
					 12VAC5-613-80.
5. The minimum absorption area for single
					 family residential dwellings shall be 400 square feet.

Current through Register Vol. 40, No. 24, July 15, 2024
A. Sand-on-sand is
					 a process of modifying a soil absorption system site using fill material which
					 is similar in texture to the original, naturally occurring material. Filling is
					 accomplished in a manner which allows for adequate treatment and disposal of
					 effluent, protection from frost and traffic damage, and does not promote the
					 creation of restrictive horizons. Sand-on-sand systems are considered Type II
					 systems and are used to overcome limitations encountered with certain high
					 water table soils. A detailed description of the siting criteria used for
					 sand-on-sand systems is found in
					 12VAC5-610-597.
B. Site preparation. All surface vegetation
					 and organic matter, including but not limited to grass, shrubs, trees, leaf
					 litter, branches, limbs, and tree stumps shall be removed. Special
					 consideration shall be given to site preparation to avoid soil compaction and
					 other damage which may create discontinuities and restrictive horizons when the
					 fill material is placed on the site.
C. Fill material. Fill material may be added
					 to such a site and used for residential onsite wastewater disposal for flows up
					 to 1,000 G.P.D. on sites meeting the criteria established in
					 12VAC5-610-597 provided that:
1. The fill material used is the same texture
					 as the underlying material;
2. The
					 coarse fragment content of the fill material is neither greater than 10% by
					 volume nor noncarbonaceous and inorganic material greater than two mm in
					 size;
3. The fill material is
					 placed in such a manner as to prevent the formation of any restrictive
					 horizons;
4. The fill material
					 covers an area 10 feet greater in all horizontal dimensions than the soil
					 absorption system;
5. The sides of
					 the filled area are sloped at not greater than 1:10 (rise:run);
6. The fill material provides at least six
					 inches of cover over all portions of the system; and
7. The fill material is stabilized to prevent
					 surface erosion.

Current through Register Vol. 40, No. 24, July 15, 2024
A. Privies are
					 divided into two categories, those that function as disposal facilities and
					 those that function merely as holding facilities with ultimate disposal of the
					 contents at another facility via pump and haul.
B. Disposal privies.
1. Pit privy.
a. Description. A pit privy consists of a
					 lined earthen pit with a suitable rodent and insect proof structure and pit
					 vent stack. The structure shall be provided with self-closing lid or lids on
					 the seat riser. The pit privy is located exterior to a dwelling.
b. Location. Required separation distances
					 from various structures and topographic features are the same as for subsurface
					 soil absorption systems and may be found in Table 4.2. The bottom of the pit
					 privy shall be at least two feet above the seasonal water table and any rock.
					 Location of pit privies shall also comply with
					 12VAC5-610-593 1 through 6 and
					 10.
c. Utilization. The Uniform
					 Statewide Building Code of Virginia normally prohibits the installation of pit
					 privies at new homes. In case of hardship, unsuitable soil conditions or
					 temporary recreational use, a privy can sometimes be constructed after
					 obtaining the approval of the building official with the approval of the
					 department. A sewage disposal system meeting the requirements of
					 12VAC5-610-250 A and B shall be
					 provided to treat other sewage (wastewater) generated from activities such as
					 laundering, bathing, handwashing, and cooking. Pit privies utilized at existing
					 dwellings should be abandoned within one year of the availability of sanitary
					 sewers. Proper abandonment consists of removing the structure and covering the
					 pit with at least two feet of soil. Pit privies are an acceptable means of
					 sewage disposal at isolated areas such as primitive camping areas, public boat
					 launching areas, recreation areas, state parks and wilderness areas where
					 pressurized water systems are not provided.

Buffer Zones

Current through Register Vol. 40, No. 24, July 15, 2024
A. All
					 anaerobic lagoons shall provide the minimum buffer zone as shown below unless
					 they qualify for reduced requirements as provided in (B) below. Buffer zones
					 are areas of controlled or limited use. Within buffer zones residential uses or
					 high density, human activities or activities involving food preparation are
					 prohibited. The extent of the buffer zone perimeter is measured from the
					 perimeter of the lagoon.
Lagoon Size:
Buffer Zone Requirement:
40,000 per day and less
500 feet
Less than 500,00 gallons per day and greater than
								40,000 gallons per day
750 feet
B. The Department shall consider reduction of
					 up to one half of the above listed buffer zone requirements based on
					 topography, prevailing wind directions, provision of covered units or the
					 inclusion of an effective wind break in the overall anaerobic lagoon design.
1. The prevailing wind direction should be
					 determined by on-site data. Local weather station records may be utilized if
					 they are demonstrated to be applicable. Attention should be paid to both
					 moderate and high speed winds since the high velocity winds often have a
					 prevailing direction different from the prevailing direction of moderate
					 winds.
2. A windbreak should be
					 located on both sides of the anaerobic lagoon normal to a line projected
					 through the plant and area which is to be protected as close to the plant as
					 practical. An effective windbreak is comprised of manmade or natural barriers
					 which extend from the ground surface to minimum height of 16 feet. A cultivated
					 tree windbreak may be developed by planting at least four rows of fast growing
					 evergreens (pine family preferred) planted on staggered 10 feet centers. Rows
					 should be spaced no greater than 16 feet apart. The variety of tree used should
					 be readily adaptable to the soil and climate at the plant site.
