A.
GENERAL
1. The Subsurface
				Wastewater Disposal System Application (HHE-200 Form) and all other required
				forms must be completed on forms developed by the Department for permits to
				install disposal systems. The application must be complete and include, but is
				not limited to, the following minimum information as outlined in the following
				sections. Except for soils and system design information, the owner/applicant
				or authorized agent is responsible for accuracy of the information provided in
				the application:
2. Page one of the
				HHE-200 form:
a. Property Location,
				Owner/Applicant Information;
b.
				Permit Information;
c. Design
				Details including the projected design flow of wastewater and method of
				calculation; and the geodetic latitude and longitude of the disposal field
				center, expressed as degrees, minutes, and seconds to an accuracy of ±
				30 feet and referenced to in the NAD 83 datum; and
d. The Site Evaluator
				Statement.
3. Page two of
				the HHE-200 form:
a. The Site Plan must be
				drawn at a scale that clearly depicts the following site features that directly
				affect the system design and compliance with this rule, and if practical,
				within the following distances within at least a 100-foot radius around systems
				with design flows less than 1,000 gallons per day, 200-foot radius around
				systems with design flows between 1,000 and 2,000 gallons per day, and at least
				a 300-foot radius around engineered systems (systems with design flows of 2,000
				gallons per day or more) and depict the following:
i. Property boundaries: The boundaries of the
				lot as indicated by the property owner;
ii. Existing manmade features: Locations of
				existing and proposed structures, roadways, water wells and disposal fields on
				the same lot and on abutting or neighboring lots to show compliance with the
				applicable setbacks;
iii. Water
				bodies: Location of all surface water bodies, natural and artificial, and all
				springs;
iv. Wetlands: The
				boundaries of any potential wetland area;
v. Locations of all observation
				holes;
vi. The location of the
				proposed system and existing disposal system if present including, but not
				limited to, disposal fields, septic tank, pump/dosing tanks and grease
				interceptors and connecting piping (a supplemental site plan may be included
				should additional space be required);
vii. Surface water diversions: Location of
				existing and proposed surface water diversions;
viii. Site location map;
ix. North arrow; and
x. Graphic Scale: Each design on this page
				must include a graphic scale.
b. Soil Profile Description and Soil
				Condition Logs, pursuant to Section
				5:
i.
				Soil profile and condition, limiting factor and depth to limiting
				factor;
ii. Ground Slope: Magnitude
				and direction of the maximum ground slope at the observation
				hole.
4. Page
				three of the HHE-200 form:
a. The Subsurface
				Wastewater Disposal Plan must be drawn at a scale that clearly depicts the
				following:
i. The location and type of the
				proposed system including, but not limited to, disposal fields, pump/dosing
				tanks, distribution pipes, connecting piping, fill material extensions with
				their shoulders and limits, septic tanks, grease interceptors and curtain
				drains;
ii. Elevations: The
				original ground elevation at the highest point along the uphill edge of each
				disposal field, and the original ground elevation of the four corners of each
				disposal field, all referenced to the elevation reference point. The number of
				ground surface elevation measurements taken within and around a disposal field
				must be sufficient to adequately determine the required elevation of the
				disposal field and the extent of the fill material extension;
iii. Elevation Reference Point: The location
				and description of a system elevation reference point (ERP) set at elevation
				zero and located outside the fill extension areas (preferably within 100 feet
				of the field). When feasible, the ERP must be established at an easily located,
				reasonably-expected-to-be-permanent feature, (for example, a fire hydrant, a
				surveying monument, a structure, etc.) When such a feature is not available,
				the site evaluator shall set their own reasonably-expected-to-be-permanent
				feature for the ERP, (for example, using a grade stake with rebar in a flagged
				tree), which must be shown on the design or in specific notes as "no alteration
				or termination without site evaluator's approval". The distance in inches of
				the ERP above ground level at the ERP location must also be indicated.
				Elevations must be given in inches above or below the ERP except for large
				systems, those greater than 1,000 GPD, which may use a reference point set to
				the datum for the entire project and may use elevations in feet and decimal
				(tenths of feet).
iv. System ties:
				three measurements from two or more known horizontal reference points or two
				measurements from one horizontal reference point with compass bearings for each
				horizontal measurement, to a minimum of two proposed disposal field corners.
				System ties must be located outside the fill extension areas and preferably
				within 100 feet of the disposal field(s). When feasible, the system ties must
				be established at an easily located, reasonably-expected-to-be-permanent
				feature, (for example, a fire hydrant, a surveying monument, or a structure).
				When such a feature is not available, the site evaluator must set their own
				reasonably-expected-to-be-permanent feature for tie points, (for example, using
				a grade stake with rebar or setting a nail in a flagged tree), which must be
				shown on the design or in specific notes as "no alteration or termination
				without site evaluator's approval". Alternatively, system tie details may be
				shown on page 2;
v. Staked Corners:
				All four corners of the disposal field must be staked by the site evaluator
				and/or engineer. Wooden stakes or wire flags are recommended to use as
				stakes;
vi. Cross-section line: a
				line running across the proposed disposal field (perpendicular to the long axis
				of the field) which identifies the location of the cross-section diagram for
				the disposal field;
vii. The limits
				of the fill extension must be shown for each corner of the disposal area with
				dimensions shown; and
viii. Scale:
				Each design must include a graphic scale.
b. Backfill Requirements: Depths of fill
				material required at each corner of each disposal field.
c. Construction Elevations: The elevation of
				the bottom of each disposal field, the top of the distribution pipes or
				proprietary disposal devices within each disposal field and finish grade
				elevation.
d. Disposal Field
				Cross-Section: Cross-section diagrams must be drawn for each proposed disposal
				field at a scale that clearly depicts the following features:
i. Original ground surface with notes for
				site preparation including scarification and transitional horizon;
ii. Height and width of disposal field stone
				or proprietary devices with dimensions;
iii. Pipes and on-center spacing with
				dimensions;
iv. Depths of fill
				material required;
v. Fill crown
				slope and shoulders with dimensions;
vi. Limits of all fill extensions with
				dimensions:
5.
				Proprietary Products: The site evaluator shall clearly indicate on the HHE-200
				form or on an attachment to same, his or her relationship with a company or
				concern that sells or distributes proprietary devices.
6. Applicable Laws, Ordinances, and
				Regulations: The completed HHE-200 Form must conform to all provisions of
				applicable laws, ordinances, and regulations, including those administered by
				public water systems.
7. The LPI
				may authorize changes to the location(s) of treatment tanks, lift stations,
				building sewers, distribution boxes, drop boxes, and force mains provided that
				applicable minimum setback distances are maintained. Such alterations must be
				documented by the LPI.
