Current through Vol. 42, No. 4, November 1, 2024

Section 785:35-5-3 - Requirements for completion and plugging reports

(a)Completion and plugging reports. Completion and plugging reports shall be filed on electronic or hardcopy forms provided by the Board and shall be filed within sixty (60) days after completion or plugging.

(b)Groundwater wells, groundwater well test holes, fresh water observation wells, open-loop geothermal wells, and marginal quality groundwater wells. The operator shall file a completion or plugging report for each groundwater well, groundwater well test hole, fresh water observation well, open-loop geothermal well, or marginal quality groundwater well completed or plugged. The completion report must include the following information:

(1) Completion or plugging date;

(2) Latitude and longitude of the well or test hole;

(3) A lithologic description of each stratum encountered during excavation of the borehole from the land surface to the total depth of the well;

(4) A description of the finding location for the well;

(5) The well owner's name, address, and telephone number;

(6) The type of well construction;

(7) The intended use purpose of the well;

(8) Borehole specifications;

(9) Surface pipe and casing construction specifications;

(10) Screen specifications and screened interval;

(11) Surface seal and annular seal materials and interval;

(12) Completion type;

(13) Hydrologic data including the depth of static water level, depth at which groundwater was encountered during construction of the well, and the estimated yield of the well;

(14) Name of the pump installation contractor, if known and applicable;

(15) Pump horsepower and rated flow, if applicable;

(16) Depth of the bottom of the pump, if applicable;

(17) Water right permit number, if applicable;

(18) Variance request number, if applicable;

(19) Proximity to the nearest potential pollution source and the type of pollution source;

(20) Well disinfection procedure;

(21) The sampled total dissolved solids concentration of the groundwater produced by the well in parts per million (ppm); and

(22) Certification from the operator verifying the accuracy of the information on the report.

(c)Geotechnical borings, site assessment observation wells, and monitoring wells. The operator shall file a completion or plugging report for each geotechnical boring, site assessment observation well, and monitoring well completed or plugged, except as provide below. Reports for the completion or plugging of geotechnical borings, site assessment observation wells, and monitoring wells must be filed electronically. Information regarding multiple geotechnical borings, site assessment observation wells, or monitoring wells may be accumulated together in a single report if all the excavations are located in the same ten-acre tract, have substantially the same lithology encountered in the subsurface, and have substantially the same depth and construction. If more than one boring or well is included on a report, a site map shall be attached to the report which indicates the distance of each well or boring from permanent reference points such as streets, roads or section lines. A report need not be filed for a geotechnical boring 20 feet deep or less in which groundwater or contamination is not present. The completion report must include the following information:

(1) Completion date;

(2) Latitude and longitude of the well or test hole;

(3) A lithologic description of each stratum encountered during excavation of the borehole from the land surface to the total depth of the well;

(4) A description of the finding location for the boring or well;

(5) The owner's name, address, and telephone number;

(6) The type of boring or well construction;

(7) The intended use purpose of the boring or well;

(8) Borehole specifications;

(9) Surface pipe and casing construction specifications, if applicable;

(10) Screen specifications and screened interval, if applicable;

(11) Surface seal and annular seal materials and interval, if applicable;

(12) Hydrologic data including the depth of static water level and the depth at which groundwater was encountered during construction of the well;

(13) Variance request number, if applicable; and

(14) Certification from the operator verifying the accuracy of the information on the report.

(d)Closed-loopgeothermal (heat exchange) wells. The operator shall file a completion or plugging report for each closed-loop geothermal well completed or plugged.Information regarding multiple closed-loop geothermal wells may be accumulated together in a single report if all of the excavations are located in the same ten-acre tract, have substantially the same lithology encountered in the subsurface, and have substantially the same depth and construction. If more than one well is included on a report, a site map shall be attached to the report which indicates the distance of each well or boring from permanent reference points such as streets, roads or section lines. The completion report must include the following information:

(1) Completion date;

(2) Latitude and longitude of the well(s);

(3) A lithologic description of each stratum encountered during excavation of the borehole from the land surface to the total depth of the well(s);

(4) A description of the finding location for the well(s);

(5) The well owner's name, address, and telephone number;

(6) Borehole specifications;

(7) Surface pipe and casing construction specifications, if applicable;

(8) Heat exchange loop material specifications;

(9) Grout sealing materials and interval;

(10) Variance request number, if applicable;

(11) Proximity to the nearest potential pollution source and the type of pollution source; and

(12) Certification from the operator verifying the accuracy of the information on the report.

(e)Plugging reports. The plugging report for groundwater wells, groundwater well test holes, fresh water observation wells, marginal quality groundwater wells, geothermal wells, monitoring wells, site assessment observation wells, and geotechnical borings must contain the following information:

(1) Plugging date;

(2) Latitude and longitude of the well, test hole, or boring;

(3) A description of the finding location for the well;

(4) The well owner's name, address, and telephone number;

(5) The type of well construction;

(6) The former use purpose of the well;

(7) Casing removal or perforation interval;

(8) Backfill material and installation depth;

(9) Grout and sealing materials, methods, and installation depth;

(10) Well identification number, if known and applicable;

(11) Water right permit number, if applicable;

(12) Variance request number, if applicable;

(13) Proximity to the nearest potential pollution source and the type of pollution source; and

(14) Certification from the operator verifying the accuracy of the information on the report.
