(III)        porosity;

(F)           remolded sample of cover soils that provide:

(d)           A conceptual design plan presenting special engineering features or considerations which must be included or maintained in site construction, operation, maintenance and closure.

(e)           Local government approvals:

(i)            If the site is located within an incorporated city or town, or within the extra-territorial jurisdiction of an incorporated city or town, the approval of the governing board of the city or town shall be required.  Otherwise, the approval of the Board of Commissioners of the county in which the site is located shall be required.  Approval may be in the form of either a resolution or a vote on a motion.  A copy of the resolution, or the minutes of the meeting where the vote was taken, shall be forwarded to the Division.

(ii)           A letter from the unit of government having zoning jurisdiction over the site which states that the proposal meets all of the requirements of the local zoning ordinance, or that the site is not zoned.

(f)            A discussion of compliance with siting standards in Rule .0503(1) of this Subchapter.

(g)           A report indicating the following:

(i)            population and area to be served;

(ii)           type, quantity and source of waste;

(iii)          the equipment that will be used for operating the site;

(iv)          a proposed groundwater monitoring plan including well location and schematics showing proposed screened interval, depth and construction; and

(v)           a more detailed geologic report may be required depending on specifics of the site.  This report may be based on physical evidence, initially, or due to information obtained from the site plan application.

(h)           Any other information pertinent to the suitability of the proposed site.

(2)           The following information shall be required for reviewing a construction plan application for a proposed sanitary landfill:

(a)           A map showing existing features to include:

(i)            existing topography of the site on a scale of at least 1 inch equals 200 feet with five foot contours;
