The following criteria shall apply in significant recharge areas established by this division:

(a)

New agricultural waste impoundment sites. New agricultural waste impoundment sites exceeding 50 acre-feet shall be lined. As a minimum, the liner shall be constructed of compacted clay having a thickness of one-foot and a vertical hydraulic conductivity of less than 5 x 10-7 centimeters/second or other criteria established by the U.S. Soil Conservation Service.

(b)

Minimum lot size. New homes or lot divisions for homes or other uses and served by septic tank/drain field systems shall be on lots having a minimum lot size of at least one hundred ten percent of the minimum size identified on table MT-1 of the Georgia Department of Human Resources' Manual for On-Site Sewage Management Systems (hereinafter "DHR Table MT-1"); provided, however, that any lot of record existing on the date of initial adoption of significant groundwater recharge area regulations by Jackson County shall be exempt from the minimum lot size established by this paragraph. No construction may proceed on a home to be served by a septic tank unless the Jackson County Environmental Health Department first approves the proposed septic tank installation as meeting the requirements of the Georgia Department of Human Resources' Manual for On-Site Sewage Management Systems.

(c)

Hazardous material handling and hazardous waste. New facilities permitted or to be permitted to treat, store, or dispose of hazardous waste shall perform such operations on an impermeable pad having a spill and leak collection system.

Above-ground storage tanks. New above-ground 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. (Note: These figures are consistent with 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.

(e)
