Virginia Administrative Code › Title 12 - HEALTH › Agency 5 - DEPARTMENT OF HEALTH › Chapter 640 - ALTERNATIVE DISCHARGING SEWAGE TREATMENT REGULATIONS FOR INDIVIDUAL SINGLE FAMILY DWELLINGS › Part II - Procedures › Section 12VAC5-640-240 - Application for a construction permit

Current through Register Vol. 40, No. 24, July 15, 2024
A. After a satisfactory site for a
				  discharging system has been found and a General Permit has been obtained from
				  the Department of Environmental Quality, the applicant shall submit an
				  application, the appropriate fee, construction plans, specifications, design
				  criteria and calculations, and documentation that coverage under the General
				  Permit has been obtained. The documentation shall include the cover letter and
				  copy of the General Permit issued by the Department of Environmental Quality.
				  If the discharge is to a wetland, the construction submittal must include
				  documentation that a Virginia Water Protection Permit from the Department of
				  Environmental Quality or a permit under the U.S. Army Corps of Engineers has
				  been obtained as needed. The purpose of the construction submittal is to
				  demonstrate how the effluent limitations established by the SWCB and the
				  construction, location, and performance requirements of this chapter can be
				  met.
B. All plans for alternative
				  discharging systems shall bear a suitable title showing the name of the owner
				  and shall show the scale in feet, a graphical scale, the north point, date,
				  revision dates (when applicable), and the name of the licensed professional
				  engineer by or under whom prepared. The cover sheet and each plan sheet shall
				  bear the same general title identifying the overall sewage disposal project and
				  each shall be numbered. Appropriate subtitles shall be included on the
				  individual sheets.
The plans shall be clear and legible. Plans shall be drawn
					 to a scale that permits all necessary information to be plainly shown. The size
					 of the plans shall be no larger than 30 inches by 48 inches. Data used should
					 be indicated. The precise location of the proposed system shall be shown on the
					 plans. Detailed plans shall consist of plan views, elevations, sections, and
					 supplementary views that together with the specifications and general layouts
					 provide the working information for the contract and construction of the work,
					 including dimensions and relative elevations of structures, the location and
					 outline form of equipment and components to be installed, the location and size
					 of piping, water levels, ground elevations, and erosion control abatement
					 facilities.
C. Complete
				  technical specifications for the construction of the alternative discharging
				  system and all appurtenances shall accompany the plans. The specifications
				  accompanying construction drawings shall include, but not be limited to, all
				  construction information not shown on the drawings, necessary to provide the
				  installer with all detail of the design requirements as to the quality of
				  material workmanship and fabrication of the project; type, size, strength,
				  operating characteristics, and rating of equipment; allowable infiltration,
				  machinery, valves, piping, and jointing of pipe; electrical apparatus, wiring,
				  and meters; operating tools and construction materials; special filter
				  materials such as stone, sand, gravel, or slag; miscellaneous appurtenances;
				  chemicals when used; instructions for testing materials and equipment deemed
				  necessary to meet design standards; and operational testing for the complete
				  works and component units.
D. At a
				  minimum, the construction submittal must show the following:
1. Information gathered in the site review
				  evaluation;
2. For each system
				  component, the plan shall note the type of component and, where applicable, the
				  manufacturer, model number, approval, status in accordance with 12VAC5-640-432,
				  hydraulic capacity, and treatment capacity;
3. The specific location of the property
				  including the county tax map number (where available), a copy of the United
				  States Geological Survey 7.5 minute topographic map showing the discharge point
				  and downstream for one mile, and directions to the property;
4. The elevation of the house sewer line
				  where it exits the house and the elevation of the inlet and outlet ports or
				  tees on all treatment units. Where discharges are to dry ditches or
				  intermittent streams the site plan shall show the elevation of the discharge
				  point, the point 500' downgrade from the discharge point and points every 50
				  feet between the discharge point and 500' downstream. This requirement may be
				  met by drawing a flow diagram showing all elements listed in this
				  section;
5. The distance between
				  all elevation points required by
				  12VAC5-640-240 D 4 so that the
				  grade and setback distances can be established;
6. If a pump is proposed, specifications must
				  be provided that include the manufacturer, model number, and a pump curve with
				  a system curve overlain on the pump curve;
7. The location of the 100-year flood plain.
				  All portions of a discharging system, except for the discharge pipe and step
				  type post aeration, if required, shall be located above the 100-year flood
				  plain;
8. Compliance with
				  12VAC5-640-430 through
				  12VAC5-640-470; and
9. Other information as deemed appropriate by
				  the department to verify the design.
