§ 13.12.270. Water wells—Classes of permits.

There shall be five types of water well permits, namely Class IA, Class IB, Class II, well reconstruction and well destruction.

A.

Class IA permits shall be obtained for the installation of a water well where such well location conforms with the minimum distances set forth in Section 13.12.340, and where the director deems no conditions exist which may result in a pollution or contamination of the ground water.

B.

Class IB permits shall be obtained for the installation of a new or replacement water well when such well is or will be the sole source of water supply and the well location is closer than the minimum distances set forth in Section 13.12.340, or where the director deems conditions exist which may result in contamination or pollution of the ground water unless special construction features are included in the well construction. A Class IB well permit shall not be issued unless there exists on a parcel an existing constraint which prohibits the construction of a Class IA well. At a minimum, special construction features shall include the following:

1.

An annular seal having a minimum thickness of three inches.

2.

An annular seal having a minimum depth of fifty feet or into the first impervious layer, whichever is greater.

3.

The sealing material to be placed in the annular space by means of a tremie pipe, so as to fill the annular space from the bottom.

4.

The well log must be made available to the director prior to sealing the annular space.

5.

Different and/or additional standards from subsections (1) through (4) above may be imposed by the director if the proposed well is to be located in close proximity to a potential source of contamination. Such standards will be conditioned on the construction permit.

In no case shall a Class IB well permit be issued when the distance to any part of a sewage disposal system is less than fifty feet.

C.

Class II permits may be issued for replacement wells serving existing residential structures if it is determined by the director that special circumstances exist whereby the criteria for a Class IB permit cannot be met due to existing constraints on the property. Special construction requirements as determined by the director will be imposed.

D.

Reconstruction permits shall be obtained for any well reconstruction work.

E.

Destruction permits shall be obtained for any well destruction work.
