Current through Rules and Regulations filed
				through June 27, 2024
(1) 40 CFR Part 280, Subpart F is hereby
				incorporated by reference.
(2)
				Corrective action plans (CAPs), Part A for reporting completed release response
				activities and for summarizing the proposed site investigation, including a
				schedule for submittal of a CAP - Part B, and Part B for reporting the results
				of the site investigation and for summarizing the proposed soil and groundwater
				corrective action objectives and the activities required to meet those
				objectives, shall be submitted to the Division on such forms as provided by the
				Environmental Protection Division, Georgia Department of Natural Resources. The
				plans must include certifications by the UST owner or operator, in the format
				specified, that the plans are factual and meet all the criteria and
				requirements of these Rules and other environmental laws and regulations of the
				State of Georgia. The plans must also be stamped or sealed by a
				Georgia-registered Professional Engineer or Professional Geologist. The
				Corrective Action Plan - Part A shall be submitted in lieu of the initial
				abatement report, the initial site characterization report, and the free
				product removal report, as referenced by
				40 CFR
				280.62(b),
				280.63(b), and
				280.64(d),
				respectively, and must be submitted to EPD within 60 days after release
				confirmation.
(3) A Corrective
				Action Plan - Part B must be submitted when one or more of the conditions
				listed in subparagraphs (a) through (e) below are encountered:
(a) Free product exceeds one-eighth inch
				(1/8") thickness or an alternate thickness, as required by EPD;
(b) Groundwater or surface water
				contamination exceeds federal and state in-stream water quality standards, as
				established by the Georgia Rules for Water Quality Control (Chapter 391-3-6, as
				amended);
(c) Groundwater
				contamination exceeds federal and state Maximum Contaminant Levels for Safe
				Drinking Water, and either;
(i) The plume is
				located in an area of average or higher groundwater pollution susceptibility,
				as defined by the Ground-Water Pollution Susceptibility Map of Georgia (Georgia
				Department of Natural Resources, Environmental Protection Division, Georgia
				Geologic Survey, 1992), within two (2) miles of a point of withdrawal for a
				public water system, as defined in the Georgia Rules for Safe Drinking Water
				(Chapter 391-3-5, as amended), and/or within one-half (1/2) mile of a point of
				withdrawal for a non-public water system; or
(ii) The plume is located in an area of lower
				groundwater pollution susceptibility within one (1) mile of a point of
				withdrawal for a public water system and/or within one-quarter (1/4) mile of a
				point of withdrawal for a non-public water system;
(d) Concentrations of volatile organic
				compounds and/or polynuclear aromatic hydrocarbons, as appropriate, in soil
				exceed:
(i) Threshold levels listed in Table
				A; or
(ii) Threshold levels listed
				in Table B; or
(iii) Alternate
				threshold levels, as approved by EPD.
