Section 26.04.07.15 - Sanitary Landfills - Rubble Landfills - Phase II

A. Phase II Report-Site Geology. The applicant shall prepare and submit to the Approving Authority ten copies of a Phase II report describing the soils, geology, and hydrology of the proposed site. This report shall be developed and signed by a geologist who possesses at least a bachelor's degree from an accredited college or university in the field of geology or a related field of earth science. The Phase II report shall include the following information in sufficient detail to permit a comprehensive review of the project:

(1) A topographic map which is an accurate depiction of the site at the time of the preparation of the Phase II Report using a contour interval which is practical for that site. The following items shall be shown on the map:

(a) Surface waters and natural drainage features;

(b) 100-year flood plain;

(c) Property lines;

(d) On-site buildings and structures;

(e) Forested and other vegetated areas; and

(f) The location of any buried or overhead power transmission lines, utility pipelines, or storage tanks on the property.

(2) A discussion of the geologic formations directly underlying and in close proximity to the site, the present and projected use of these formations as a ground water source, and the hydrogeologic relationship between the formations.

(3) A survey of all production wells within 1/2 mile of the site boundary. Each well shall be located on the current topographic map and a table shall be developed which specifies all the available pertinent information such as well depth, screen type, productivity, lithology penetrated, and water level.

(4) A minimum of three separate ground water contour maps superimposed on the current topographic map to represent the occurrence and direction of ground water flow beneath the site for a period of time not less than 12 months in duration. The three separate ground water contour maps shall be constructed for each distinct water-bearing formation occurring within 50 feet of the anticipated lowest elevation of the refuse cell floor using monthly ground water elevation data collected from piezometers on or near the site, from available historical sources of ground water information, or using a hydrologic simulation or predictive technique approved by the Department. One ground water contour map shall be constructed from a set of:

(a) Water elevations measured or predicted during the month that best represents:

(i) An elevated ground water condition,

(ii) A depressed ground water condition;

(b) The highest observed or predicted water elevations.

(5) Geologic cross sections in sufficient detail, orientation, and number to clearly identify subsurface conditions at the site.

(6) A bedrock contour map (except in the coastal plain outside the fall zone) to show the elevation of the bedrock surface beneath the site.

(7) An isopachous map to show the thickness of soil and other unconsolidated sediments above the elevation of ground water as determined in §A(4) of this regulation, or bedrock as determined in §A(6) of this regulation, whichever is higher.

(8) A discussion of the chemical quality of ground water in the aquifers beneath the site as determined in §A(2) of this regulation. The list of chemical parameters shall include:

(a) pH;

(b) Alkalinity;

(c) Hardness;

(d) Chloride;

(e) Specific conductance;

(f) Nitrate;

(g) Chemical oxygen demand;

(h) Arsenic;

(i) Barium;

(j) Cadmium;

(k) Chromium;

(l) Zinc;

(m) Lead;

(n) Mercury;

(o) Volatile priority pollutants;

(p) Other pollutants specified by the Department.

(9) A discussion of the potential for the vertical and horizontal movement of pollutants into the waters of the State.

(10) The results of a fracture trace or aerial photographic lineament analysis (except in the coastal plain) which identifies the relationship between these features and the local ground water hydrology.

(11) Test boring logs, well completion reports, piezometric measurements, chemical and physical soil/sediment analyses, and all accompanying geotechnical analyses. All laboratory and field methodologies and procedures shall be included.

(12) A preliminary conceptual design of the proposed rubble landfill based on the geotechnical information gathered in §A(1)-(11) of this regulation.

B. Phase II-Plan Review.

(1) Following receipt of the specified number of copies of the Phase II report, the Department shall distribute one copy to each of the following:

(a) Secretary, Department of Natural Resources;

(b) Director, Water Management Administration;

(c) Director, Maryland Geological Survey;

(d) U.S. Geological Survey;

(e) County Soil Conservation District;

(f) Chief executive officer or the governing body, or both, of the county or municipality in which the activity is proposed;

(g) Local health official; and

(h) Local operating agency responsible for solid waste management.

(2) A person receiving a copy of the Phase II report shall be requested to submit any comments to the Department within 30 days of receipt of the report.

(3) The Department shall set a date, time, and place for a joint plan review meeting with interested agencies and the applicant.

(4) When practicable, within 60 days following this meeting, the Approving Authority shall either deny the permit or determine if:

(a) Sufficient information is available to proceed to the Phase III report; or

(b) Revisions to the Phase II report are needed.

(5) If the Department is unable to complete the review within the established 60-day time schedule, the Department shall notify the applicant in writing within 30 days of receipt of the information and inform the applicant of the anticipated time required to complete the review.
