Current through Register No. 50, December 12, 2024

Section Env-Dw 305.28 - Final Report: Contents

The applicant shall provide the following pursuant to Env-Dw 305.26(c)(2):

(a) A description of the pumping test, including:

(1) All of the data collected;

(2) A description of how each pumping test requirement in the approved preliminary report was met;

(3) A graph developed using the following methodology:

a. Water level data shall be plotted as a semi-logarithmic plot of drawdown versus elapsed time, expressed in minutes elapsed since pumping began, presented on the logarithmic axis; and

b. A straight line shall be:

1. Drawn through the data on the semi-logarithmic plot with a slope based on the data points from the end of the pumping period; and

2. Used to extrapolate the drawdown for a time of 180 days, or 259,200 minutes, which shall be the theoretical 180-day drawdown; and

(4) If an alternate pumping test method was approved in the preliminary report, all data and analyses as approved in the preliminary report and the justification for the alternative method required by Env-Dw 305.14(a)(2);

(b) A description of the water quality sampling program, with specific note of any deviations from the program as approved in the preliminary reports, and copies of all laboratory results;

(c) A description of the method used to refine the wellhead protection area;

(d) Updated contamination source and water use inventories;

(e) A description of the contamination risk control program with supporting evaluations and documentation;

(f) A description of the wellhead protection program, including:

(1) The name, title, mailing address, daytime telephone number, and email address, if any, of the person who is or will be responsible for implementing the wellhead protection program; and

(2) A copy of or reference to the education materials;

(g) A copy of the well completion report prepared in accordance with We 800;

(h) A proposed permitted production volume and a description of the means by which it was established in accordance with Env-Dw 305.20;

(i) An estimate of the effect pumping the permitted production volume from the well will have on:

(1) Water levels in private and public wells within 1,000 feet of the production well;

(2) Water levels in nearby surface waters and wetlands;

(3) Existing groundwater contamination plumes; and

(4) Saltwater intrusion into the freshwater aquifer;

(j) A vulnerability assessment of potential impacts to the well from natural hazards, if necessary based on:

(1) The site's location relative to surrounding topographic and hydrologic features that pose a reasonable threat to the facility's structural integrity or functionality, or both; or

(2) The well location's history of impacts by natural hazards; and

(k) Documentation of legal control of the sanitary protective area.
