Where special hazards are involved the distance required shall be increased, as may be directed by the health officer or the administrative authority.
4
Plus two feet for each additional foot of depth in excess of one foot below the bottom of the drain line. (See also section 1-6
5
See Section 720.0 of the California Plumbing Code.

Tables K-4 and K-5 on page 463 are hereby superseded and replaced by the following:
RATED ABSORPTION CAPACITIES OF TYPICAL SOILS
The rated absorption capacities of soils in Kings County are as shown on Figure B. The required square feet of leaching area for each disposal system shall be based on the rated absorption capacity unless percolation tests acceptable to the administrative authority are conducted on the site of the disposal unit and where such tests are made, the leaching area shall be based on the test information in accordance with the "Manual of Septic Tank Practice" by the U.S. Health Service, PB 218 226, Table 1 located on page 6.

Type of Soil

| C | 90 |
The minimum disposal area shall conform with the following:
* Areas that are within the minimum distances which are necessary to protect water quality shall not be used for waste disposal. The following areas are also considered unsuitable for the location of disposal systems or expansion area:
a.
Areas within any easement which is dedicated for surface or subsurface improvement.
b.
Paved areas.
c.
Areas not owned or controlled by property owners unless said area is dedicated for waste disposal purposes.
d.
Areas occupied or to be occupied by structures. Soil depth below the bottom of the leaching trench shall not be less than five feet, nor less than ten feet below a seepage pit.
In critical water areas, as indicated on Figure B, engineered plans are required. Their design shall be governed by "Guidelines For Waste Disposal From Land Developments," California Regional Water Quality Control Board, "Manual of Septic Tank Practice" by U.S. Dept. of Health, Education, and Welfare, and the "Uniform Plumbing Code," 1994 Edition.
