All uses, except those identified in section 26-84 and those subject to further restriction by any underlying zoning district, are allowed. The following are additional requirements for specific uses:

(1)

All new aboveground chemical or petroleum storage tanks, having a minimum volume of 660 gallons, shall have secondary containment for 110 percent of the volume of such tanks or 110 percent of the volume of the largest tank in a cluster of tanks, and shall otherwise meet the requirements of US EPA rules for oil pollution prevention, 40 CFR 112.1. Such tanks used for agricultural purposes are exempt, provided they comply with all federal requirements.

(2)

All single-family dwellings, multifamily dwellings, mobile home parks, or other uses located within a groundwater recharge area and not served by both public water and sewer systems shall be required to have 150 percent of the minimum lot or space size calculated based on application of the state department of human resources manual for On-Site Sewage Management Systems (DHR Manual) Tables MT-1 and MT-2 (included as part of this article in appendix 1). The minimums set forth in Tables MT-1 and MT-2 may be increased further based on consideration of other factors (set forth in sections A-F) of the DHR Manual. Said minimum lot size shall not be in any case less than the minimum lot size specified by any underlying zoning district. The regulations specifying the largest minimum lot size shall apply.

(3)

All lots shall have a minimum width of 150 feet, or as specified in any underlying zoning district if stricter (larger), in the area where an approved on-site sewage management system is to be located.

(4)

No construction may proceed on a building or mobile home to be served by a septic tank or other on-site sewage management system unless the county health department first approves the proposed on-site sewage management system installation as meeting the requirements of the Georgia Department of Human Resources Manual for On-Site Sewage Management Systems and the provisions of this article.

(5)

All new wastewater treatment basins shall have an impermeable liner except for the construction of mining settling basins.

(6)

All new agricultural waste impoundment sites shall be lined. As a minimum, the liner shall be constructed of compact clay having a thickness of one foot and a vertical hydraulic conductivity of less than 5 × 10 ^-7 cm/sec or other criteria established by the US Natural Resources Conservation Service.
