10)         proposed pump test procedures;

 

11)         sampling procedures, if necessary under 35 Ill. Adm. Code 611.212, for wells that may be subject to surface water influences;

 

12)         the type, design capacity, head rating, and depth of pump setting;

 

13)         the column pipe diameter, length, material, and joint;

 

14)         the discharge pipe diameter, depth of cover, material, and valving;

 

15)         the casing vent diameter;

 

16)         the airline length;

 

17)         the location of the raw water sample tap;

 

18)         a description of how the top of the well casing is sealed;

 

19)         a description of access to the well site; and

 

20)         well hydraulics and aquifer property data.

 

c)         The following information must be submitted on plans for well construction permit applications:

 

1)         the well location with the following information:

 

A)        a 2,500-foot radius showing the location of potential routes, potential primary sources, and potential secondary sources of contamination;

 

B)        cleanup sites within 2,500 feet of the proposed well site with any of the following:

 

i)          No Further Remediation (NFR) letter;

 

ii)         Groundwater Management Zone (GMZ);

 

iii)        Environmental Land Use Covenant (ELUC); or

 

iv)        an ordinance that restricts the use of groundwater; and

 

C)        a 400-foot radius showing the location of the sources of pollution listed in 35 Ill. Adm. Code 604.150(a);

 

2)         a cross-section of the well showing finished grade, natural ground surface, vent, casing, column pipe, screen, well depth, pump depth, grout, gravel pack, and discharge piping;

 

3)         all discharge piping, including pressure gauge, meter, sample tap, check valve, shut-off valve, and vacuum/air release valve, if applicable;

 

4)         well house construction, if provided;

 

5)         the locations of all electrical junction boxes;

 

6)         the locations of all observation wells; and

 

7)         piping showing the ability to pump to waste.

 

d)         The following information must be submitted on plans for surface water intake construction permit applications:

 

1)         plan and profile views of the intake structure showing the location, elevation of intake ports, fish screens, valves, piping, and pumps, if applicable;

 

2)         for sites subject to flooding, the maximum flood level based upon the highest flood level specified in the best available information, such as the flood of record, the 100-year flood projection, or the 500-year flood projection;

 

3)         location of inspection manholes, if applicable; and

 

4)         location of chemical treatment, if applicable.
