Current through Register Vol. 48, No. 9, September 27, 2024

1. The Department may gather and/or require the submission of hydrologic and geologic information on the aquifer or aquifers in and adjacent to a designated capacity use area for the purpose of evaluating and managing the groundwater resource.

2. Required information may include, but not be limited to, the following:

a. Surface and/or subsurface geologic mapping;

b. Areas of groundwater recharge and amount of recharge;

c. Drilled well cuttings and/or drilled well cores;

d. Geophysical logs;

e. Pumping test to establish hydraulic characteristics of an aquifer(s);

f. Static and pumping water levels of wells;

g. Groundwater availability and flow;

h. Water quality analyses;

i. Amount of groundwater withdrawal from the aquifer(s); and

j. Drill test, monitor or observation wells.

3. All persons who are required to obtain a Groundwater Withdrawal Permit under this regulation shall furnish the Department such additional geologic and hydrologic information and well construction data as the Department requires which may include, but not be limited to, the following:

a. Collection of drill cuttings at ten foot intervals and/or at lithological changes of the stratigraphy, showing depth, in feet, below ground surface, at which the cuttings were collected;

b. Geophysical logs, where the Department finds additional information on the geology, hydrology or well construction is required;

c. Data on all water bearing zones encountered;

d. Drill stem or packer tests;

e. Pumping test data;

f. Water quality analyses; and

g. Completed DHEC Water Well Record or other approved reporting form.

4. Any person drilling a test or exploration well for the purpose of obtaining geologic and/or hydrologic information on water or mineral resources in a designated capacity use area shall apply for a permit to construct in accordance with Section E from the Department to drill such well and shall submit to the Department the information identified in this Section; provided that no person shall be required to disclose any secret formula, process or methods used in any manufacturing operation or any confidential information concerning business activities carried on by him or under his supervision; provided, however, if the information is necessary for the Department to make a determination on a permit application or modification, the Department may deny such permit on the grounds that the applicant failed to provide the necessary information. In addition to the information required under Section E the following information shall be submitted on forms provided by or approved by the Department prior to the drilling of a test, exploration, or observation well:

a. Name and address of applicant who shall be the owner and his applicable agent, professional engineer, or professional geologist, as appropriate;

b. Intended purpose of the well(s);

c. Name and address of owner(s) of property on which the proposed test, exploration, or observation well(s) is to be located;

d. Proposed location(s) of all test, exploration, or observation well(s), identified by number, for which the permit is requested, marked on the best available map;

e. Proposed depth(s) of all test, exploration, or observation well(s), the diameter(s), and proposed method of drilling and construction;

f. Type of casing, screen, and other materials to be used in construction of the well(s);

g. Type of borehole logs, including geophysical logs, to be run on the well(s); and

h. Proposed method of abandonment.

5. Upon completion of the test, exploration, or observation well(s) the following information shall be submitted to the Department:

a. A completed SCDHEC Water Well Record or other approved form;

b. As-built construction diagram of the completed well, showing hole sizes and depths, casing sizes, and screen (if applicable), grout location, and construction materials;

c. Elevation data;

d. Aquifer test or pumping test data;

e. Driller's log, geologist's or engineer's log;

f. Geophysical logs; and

g. Method of abandonment (if applicable).

6. All test, exploratory, and observation well(s) drilled and not developed for groundwater withdrawal shall be filled, plugged, and sealed in accordance with Section N.

7. Wells without pumps which are declared not to be abandoned shall be fitted with a secure cap when they are not being used as observation wells or for other purposes.
