(2)

The disposal area where domestic septage is to be applied shall meet the requirements in Section 4 of this administrative regulation.

(3)

The following documents shall accompany the application:

(a)

A plat or recording in the local county clerk's office, an original and current 7.5 minute U. S. Geological Survey Quadrangle topographical map with proposed site boundaries clearly marked, or dimensioned site plan showing:

1.

Number of acres and site boundaries;

2.

Structures and other facilities;

3.

Proposed disposal area;

4.

Setback distances for features on the site and adjacent to the site as listed in Section 4, Table 8, of this administrative regulation;

5.

North and prevailing wind direction; and

6.

Access roads and other features outside of the boundaries of the site that may have an impact on site approval.

(b)

Proposed operations plan including:

1.

Methods and equipment for application, treatment, recycling, or storage;

2.

Land usage and the nitrogen requirement for the crop or vegetation;

3.

Application rate;

4.

Monitoring program for vector and pathogen reduction;

5.

State and federal endangered species impact statement, if applicable; and

6.

Other information determined as necessary by the cabinet.

Section 3.

Site Evaluation Fee.

(1)

An evaluation fee shall be required for the cost of conducting a site evaluation by the local health department.

(2)

In accordance with KRS 211.355, the site evaluation fee shall be established by the local board of health having jurisdiction.

Section 4.

Site Approval Procedures.

(1)

A certified inspector shall evaluate each proposed site based on the factors listed in Tables 1 through 8 of this section. An official site evaluation form shall be completed classifying each factor using the following rating method:

(a)

An "A" rating means that the site is acceptable for that site factor.

(b)

An "M" rating means the site factor is acceptable with modification or restriction to the site or disposal method.

1.

M1 - Upslope surface water diversion required.

2.

M2 - Shallow placement of domestic septage shall maintain a minimum separation distance of eighteen (18) inches between the domestic septage and a water table or bedrock. Lined wetland cells, storage, or treatment facilities may be excluded from this requirement;

3.

M3 - Shallow placement of domestic septage shall be required to maintain a minimum separation distance of eighteen (18) inches between the domestic septage and a restrictive horizon.

4.

M4 - Acceptable if a curtain drain is installed to lower the water table to a level of eighteen (18) inches below the domestic septage application.

(c)

A "U" rating means the site factor is not acceptable. Reclamation site areas with "U" ratings may be acceptable for disposal sites if the disposal activity will not contaminate the groundwater or create a public health nuisance.
