(3)           engineering calculations including hydraulic and pollutant loading for each treatment unit, treatment unit sizing criteria, hydraulic profile of the treatment system, total dynamic head and system curve analysis for each pump, buoyancy calculations, and irrigation/infiltration design.

(d)  Site plans.  If required by G.S. 89C, a professional land surveyor shall provide location information on boundaries and physical features not under the purview of other licensed professions.  Site plans or maps shall be provided to the Division by the applicant depicting the location, orientation and relationship of facility components including:

[Note:  The North Carolina Board of Examiners for Engineers and Surveyors has determined, via letter dated December 1, 2005, that locating boundaries and physical features, not under the purview of other licensed professions, on maps pursuant to this Paragraph constitutes practicing surveying under G.S. 89C.]

(1)           a scaled map of the site, with topographic contour intervals not exceeding 10 feet or 25 percent of total site relief and showing all facility-related structures and fences within the treatment, storage and disposal areas, and soil mapping units shown on all disposal sites;

(2)           the location of all wells (including usage and construction details if available), streams (ephemeral, intermittent, and perennial), springs, lakes, ponds, and other surface drainage features within 500 feet of all waste treatment, storage, and disposal site(s) and delineation of the review and compliance boundaries;

(3)           setbacks as required by Rule .0706 of this Section; and

(4)           site property boundaries within 500 feet of all waste treatment, storage, and disposal site(s).

(e)  A hydrogeologic description prepared by a Licensed Geologist, Licensed Soil Scientist, or Professional Engineer if required by Chapters 89E, 89F, or 89C respectively of the subsurface to a depth of 20 feet or bedrock, whichever is less, shall be provided to the Division for systems treating industrial waste and any system with a design flow of over 25,000 gallons per day.  A greater depth of investigation is required if the respective depth is used in predictive calculations.  This evaluation shall be based on borings for which the numbers, locations, and depths are sufficient to define the components of the hydrogeologic evaluation.  In addition to borings, other techniques may be used to investigate the subsurface conditions at the site.  These techniques may include geophysical well logs, surface geophysical surveys, and tracer studies.  This evaluation shall be presented in a report that includes the following components:

[Note:  The North Carolina Board for Licensing of Geologists, via letter dated April 6, 2006, North Carolina Board for Licensing of Soil Scientists, via letter dated December 1, 2005, and North Carolina Board of Examiners for Engineers and Surveyors, via letter dated December 1, 2005, have determined that preparation of hydrogeologic description documents pursuant to this Paragraph constitutes practicing geology under G.S. 89E, soil science under G.S. 89F, or engineering under G.S. 89C.]

(2)           a description, based on field observations of the site, of the site topographic setting, streams, springs and other groundwater discharge features, drainage features, existing and abandoned wells, rock outcrops, and other features that may affect the movement of the contaminant plume and treated wastewater;

(f)  Property Ownership Documentation shall be provided to the Division consisting of:
